Definitions
- This invention relates primarily to the fields of wound treatment and surgery, and more particularly, to improvements in the formation of a basin which can be used to collect liquid used in wound irrigation.
- the present invention can also be used in other fields, including non-medical applications.
- Absorbent pads are routinely used in clinics and in homes. Such pads essentially comprise a combination of an absorbent material and a fluid barrier. A mesh is typically provided over the absorbent material to retain the absorbent material against the fluid barrier, which serves as a backing for the pad.
- the present invention provides a pliable pad which can be shaped into a trough or basin (either before use or in situ) for containing excess liquid.
- the pliable pad of the present invention can prevent liquid from spilling from the trough or basin which is formed (e.g., onto the floor or onto medical personnel).
- the pliable pad of the present invention can also be used in non-medical applications such as the containment of liquid leaking from a plumbing fixture or from-a machine. This can be especially useful in situations in which a simple pan or bucket cannot be deployed because of limited access, or when such devices would provide inadequate containment of a leak or spray.
- the pliable pad can be used to overcome the problems associated with the use of simple pans or buckets by introducing the pliable pad in one configuration (e.g., flat or partially folded) and by then shaping the pliable pad, in place, to address the problems associated with limited access.
- the pliable pad can be shaped to surround the leak, to limit or even eliminate any spray that might otherwise escape.
- the pliable pad of the present invention is comprised of an absorbent material arranged adjacent to a formable material.
- the absorbent material and/or the formable material can further include a barrier to liquid, or a separate liquid barrier layer can be provided.
- the formable material is preferably chosen so that it can be shaped manually, and so that the desired shape will be retained indefinitely if left undisturbed.
- the formable material can then be manipulated by hand, or by machine, to form a wall or a series of walls, so that the pliable pad can form a fluid-collecting basin.
- the pliable pad can be made formable by mating the absorbent material with a sheet formed of a metal or a metal foil, or by embedding an elongated bendable member (e.g., a wire, rod or tube) within the absorbent material or within a sheet (or sheets) resting upon the absorbent material or to which the absorbent material is attached.
- the resulting structure will then provide an absorbent material located within a basin which is defined by the walls created by manipulating the formable material. Any liquid that is not absorbed by the absorbent-material will nevertheless be retained within the basin, providing added assurances that the fluids in question are effectively collected by the resulting structure.
- the formable material can be pre-formed to facilitate subsequent manipulation by the user into a basin-like shape. Corners and/or edges of the formable material can be attached, by being creased, mechanically fastened or bonded together, for example, using an adhesive or by welding, to further facilitate manipulation by the user. Edges of the formable material can also be folded to permit expansion of the structure to various sizes by the user.
- the formable material can be folded or rolled to create a package size which is desirable for shipping and storage.
- the absorbent material can be combined with the formable material at any point during manufacture of the pliable pad, or prior to or during subsequent shaping of the formable material by the user. This can occur when the formable material is in a generally planar configuration, when the formable material is in the process of being formed into a desired configuration, or after the formable material has been shaped into its final configuration by the user.
- the formable material, or the liquid barrier can be provided with an extension formed of a liquid-impervious material which can be folded over the pliable pad.
- the liquid-impervious material can then be draped over the wound to permit convenient irrigation of the wound while protecting the user from contact with hazardous liquid or spray.
- the liquid-impervious material is preferably, but not necessarily, transparent to further facilitate the procedure to be performed.
- a draining conduit or port can also be provided, if desired, to conduct excess liquid to a separate or external receptacle.
- a portion of the formable material can itself be shaped to create a draining conduit.
- the pliable pad of the present invention can further include one or more tabs attached to the pliable pad, one purpose of which is to provide a means for securing the pliable pad to the patient (or to a desired structure).
- the tabs can either be tied to each other, or fastened together by other means.
- the tabs can assist in supporting the walls which have been formed in their desired position, and can also provide a means for sealing the pliable pad against a patient (or to a desired structure) so that the likelihood of a leakage of liquid is reduced.
- the pliable pad of the present invention will generally include a layer (or section) formed of an absorbent material, which can include a permeable material that allows fluid to pass to the absorbent material without allowing the absorbent material to be released.
- the layer (or section) of absorbent material and the formable material can be joined together by an adhesive, by heat sealing, or by other means.
- the layer (or section) of absorbent material can be mechanically attached to the formable material (e.g., by bending over edges of the formable material to capture the layer (or section) of absorbent material) without the use of an adhesive.
- Another alternative is to simply locate the layer (or section) of absorbent material adjacent to the formable material, without being bonded to the formable material.
- Yet another alternative is to sandwich the formable material between a pair of sheets, with at least one of the sheets comprising a liquid barrier, if needed.
- the sheets can be heat welded to each other, or attached with an adhesive, to encase the formable material between the pair of sheets.
- the present invention is also directed to various uses for the pliable pad.
- the primary use for the pliable pad is in irrigating wounds. To this end, the head or a limb of a patient is placed on a pliable pad which is manipulated to form a basin to contain the appendage. The desired irrigation step is then performed. During such irrigation, liquid is capable of being absorbed by the absorbent material, and any liquid that is not absorbed by the absorbent material is collected in the basin defined by the pliable pad.
- the pliable pad of the present invention also has uses in fields other than medicine.
- the pliable pad can be used to collect water leaking from plumbing fixtures, such as sinks, or to collect liquids that drain or leak from machinery. Any of a variety of uses are possible.

- FIG. 1 shows a basic embodiment of the pliable pad of the present invention.
- pliable pad refers to the entire composite structure described below.
- the pliable pad 1 generally includes a center section 2 which is combined with a backing layer 3 .
- the center section 2 is comprised of an absorbent material, which can be formed of a superabsorbent polymer, an absorbent fabric, a pulp material, cotton or the like, or any other material capable of absorbing liquids.
- the backing layer 3 preferably forms a liquid barrier, and can be formed of one or a plurality of layers formed of selected liquid-retaining materials (which may be the same or different from one another).
- Preferred liquid-retaining materials can include any of a variety of plastic sheet materials or plastic coatings, with particularly preferred materials for developing the liquid barrier including plastic films formed of vinyl, polyethylene, polypropylene or some other equivalent plastic.
- a “formable material” which, as used in this specification, will refer to any material which is capable of assuming a desired shape and of retaining the desired shape which has been assumed.
- Preferred examples of such formable materials include thin sheets of aluminum or aluminum foil, metal wires, rods or bands, or other structurally equivalent materials.
- the formable material can be provided in a smooth condition, or can be crinkled or dimpled to increase its strength, as desired. Any of a variety of structurally formable materials can be used, provided the selected material is bendable and can retain its shape after being formed into a particular configuration.
- the selected formable material can be implemented as a single layer, as plural layers, or as a composite which includes the formable material.
- a preferred, composite formable material for use in accordance with the present invention is comprised of two layers of foil separated by a plastic film or coating between the foil layers to reduce the likelihood of leaks through any holes which might come to be formed in the foil layers.
- the formable material is preferably capable of bending in virtually any direction, for formation into an unlimited variety of shapes.
- the area of the backing layer 3 is greater than that of the center section 2 .
- the center section 2 is preferably comprised of the absorbent material and the backing layer 3 is preferably comprised of the formable material.
- the pliable pad 1 of the present invention is not limited to such an arrangement.
- the center section 2 can include the formable material together with the absorbent material. In such cases, when the pad is formed into a basin, the absorbent material will cover the walls of the basin, as well as the bottom.
- FIG. 2 shows a cross-section of the pliable pad 1 shown in FIG. 1.
- the illustrated cross-section again includes both the center section 2 and the backing layer 3 of FIG. 1.
- the center section 2 includes a layer 4 formed of the absorbent material, which is surrounded with and enclosed by an outer layer 5 (including top 6 , bottom 7 and side 8 portions), encasing the layer of absorbent material 4 .
- the primary purpose of the outer layer 5 is to allow fluid to pass through, to the absorbent material, while preventing particles or fibers of the absorbent material from being released into an open wound.
- a secondary purpose of the outer layer 5 is to provide a means for reliably locating the layer of absorbent material 4 relative to the backing layer 3 , by securing the layer 4 to the layer 3 when deemed appropriate.
- the outer layer 5 may not provide sufficient protection against the release of dust particles from the absorbent material.
- the absorbent material can be formed of a material such as absorbent gauze or superabsorbent fibers, which tend not to release particles.
- the outer layer 5 can be omitted in such cases, or retained, as preferred.
- the outer layer 5 will typically be formed of a mesh, non-woven, or equivalent material capable of allowing fluid to pass through the outer layer 5 and to the layer of absorbent material 4 contained by the outer layer 5 .
- the outer layer 5 will preferably completely encase the layer of absorbent material 4 , and either can simply rest on the layer of absorbent material 4 or can be attached to the layer of absorbent material 4 using, for example, an adhesive, heat welds, or another equivalent fastening means.
- the bottom 7 of the outer layer 5 can be omitted and the sides 8 of the outer layer 5 can be attached to the backing layer 3 .
- the outer layer 5 can be comprised either entirely of one material, such as a mesh, or can be constructed from a combination of mesh-like and liquid-impervious materials.
- a particularly preferred embodiment uses a mesh material for the sides 8 and a liquid-impervious material for the top 6 , with the bottom 7 either being omitted, made of a liquid-impervious material or made of a mesh material.
- the liquid-impervious material positioned along the top 6 of the outer layer 5 serves to keep a body part being treated from resting in a direct fluid path with the absorbent material. Fluid is then allowed to flow over the facing defined by the top 6 of the outer layer 5 , and through the mesh forming the sides 8 of the outer layer 5 to the layer of absorbent material 4 , in this way limiting the amount of fluid that the appendage contacts directly.
- the outer layer 5 can be implemented either as a single layer, with the liquid-impervious material provided along the top 6 joined at its edges to the mesh layer along one or more of the sides 8 of the outer layer 5 , or as plural sections or multiple layers of material.
- the mesh material can encase the entire layer of absorbent material 4 , with sections of liquid-impervious material forming a second layer on top of or beneath the mesh material along the top 6 and/or the bottom 7 of the outer layer 5 , so that only the sides 8 (and possibly the bottom 7 ) allow fluid to reach the layer of absorbent material 4 .
- the outer layer 5 can be eliminated if preferred. It is also possible to provide only a top portion 6 which is formed of the liquid-impervious material, and to omit the bottom 7 and the sides 8 of the outer layer 5 , if desired for a particular application.
- FIGS. 3A to 3 D show cross-sectional views of several alternative configurations for a formable backing layer 3 for the pliable pad 1 shown in FIG. 1.
- a liquid barrier layer 9 and a layer of formable material 10 jointly comprise the formable backing layer 3 .
- the formable material alone generally will not provide a sufficient liquid barrier, and the use of an additional liquid barrier layer 9 is generally preferred in such cases.
- the liquid barrier layer 9 is typically comprised of a plastic sheet, film or coating, and can be deployed above and/or below the layer of formable material 10 , as is shown in FIGS. 3B and 3A, respectively.
- FIGS. 3B and 3A show cross-sectional views of several alternative configurations for a formable backing layer 3 for the pliable pad 1 shown in FIG. 1.
- a liquid barrier layer 9 and a layer of formable material 10 jointly comprise the formable backing layer 3 .
- the formable material alone generally will not provide a sufficient liquid barrier, and the use of an additional liquid barrier layer 9 is generally preferred in such
- the liquid barrier layer 9 can be deployed as a single layer, or in multiple layers if preferred.
- FIG. 3C illustrates an embodiment which employs two layers 9 , 9 ′ formed of a liquid barrier material.
- the liquid barrier layers 9 , 9 ′ are used to contain the layer of formable material 10 .
- a liquid barrier layer 9 can also be positioned between multiple layers 10 , 10 ′ of the formable material, as is shown in FIG. 3D (which illustrates one of potentially multiple internal liquid barrier layers). Combinations of the foregoing structural configurations can also be developed, if desired.
- FIG. 4A shows an alternative embodiment for the pliable pad ( 1 ′) which is similar to the pliable pad 1 of FIG. 1, except for the thickness and the surface area of the layer of absorbent material 4 ′.
- the thickened layer of absorbent material 4 ′ shown in FIG. 4A is primarily used to support an appendage above the liquid level (i.e., above any contaminated fluid which has collected in the basin) during irrigation.
- Providing a relatively thick layer of absorbent material 4 ′ also serves to concentrate the absorbent material where most of the liquid will tend to gather.
- the thickness of the layer of absorbent material 4 in the embodiment of FIGS. 1 and 2 can be in the range of from about 1 ⁇ 8 to about 1 ⁇ 4 inches, while the thickness of the layer of absorbent material 4 ′ in the embodiment of FIG. 4A can be in the range of from about 1 to about 2 inches.
- Such thicknesses are presently considered preferred. However, other thicknesses can freely be used if preferred for a given application.
- the thickness selected for the layer of absorbent material can be developed either with a single layer of material, or in multiple layers, as preferred. Multiple layer thicknesses can be developed using plural, discrete layers of absorbent material, or by folding a layer of absorbent material into multiple layers to form a pillow shaped structure.

- FIG. 5A shows an alternative embodiment for the pliable pad ( 15 ) having an elongate bendable member 16 (e.g., a wire, rod or tube) which is combined with the layer of absorbent material 4 to serve as a formable material.
- the layer of absorbent material 4 is made formable by the stiffening effect of the member 16 which is mated with the layer of absorbent material 4 . Since the layer of absorbent material 4 is not normally also a liquid barrier, the layer of absorbent material can also be combined with one or more separate layers formed of a liquid barrier material, if desired.

- the formable backing layer 18 preferably includes a liquid barrier layer 20 , which can be positioned above (as shown by the dotted outline in FIG. 6) and/or below the formable backing layer 18 , as desired for a particular application.
- the cutout portion 19 is generally square or rectangular in shape and is located near the center of the pliable pad.
- the cutout portion is preferably located at or near the center of the pliable pad because in this region, the strength of the formable material is less critical, primarily because the center portion will normally remain flat, even after the formable material has been shaped to form a basin.
- Other configurations for the cutout region are equally possible. For example, more than one cutout portion can be provided, and the shape of the cutout portion or portions provided can be varied considerably.

- the port 26 receives fluid collected within the basin formed by the folded pliable pad 25 , for conducting the received fluid from the basin to a suitable receptacle, such as the bucket 28 .
- Use of the flanged connection shown in FIG. 9 is preferred so that the drainage port 26 (and any hose it receives) is reliably sealed against the pliable pad 25 to prevent leakage.
- Multiple drainage ports can also be used, if desired, to provide the pliable pad with plural drains (e.g., along the side or at the bottom of the pad).

The configuration shown in FIG. 11 is useful for conserving material, and as a result, reducing the costs of fabrication. It is also possible to form tabs which extend from plural positions on the pliable pad (e.g., from opposing peripheral edges of the formable backing layer), if desired.
- the tabs 34 can simply be tied together to secure the pliable pad 33 against the limb of a patient.
- one or more of the tabs 34 can be provided with an adhesive strip 36 for facilitating connection of the tabs 34 to one another.
- Any of a variety of fasteners can be used to achieve a similar result, such as a hook-and-loop arrangement or some other mechanical fastener, so that the tabs 34 can be conveniently secured to each other.
- FIG. 12 illustrates the use of tabs 34 having the adhesive strips 36 of FIG. 11 to secure a limb 37 within a defined basin 38 .
- the primary purpose of the tabs 34 is to secure the pliable pad 33 against the patient and create a seal to further prevent the leakage of liquid, and to secure the limb 37 of the patient to the pliable pad 33 .

- FIG. 18 shows an alternative embodiment for the pliable pad ( 46 ) having a pair of barrier layers 47 , 47 ′ which are heat-welded to the formable material (implemented as the member 16 ′ of FIG. 5B).
- the pair of barrier layers 47 , 47 ′ surround the formable member 16 ′, which is shown in phantom because it will then be sandwiched between the pair of barrier layers 47 , 47 ′.
- the undulating formable material serves to develop serrated edges 48 which, for convenience of illustration, are shown only on two sides. In practice, such serrations can be established on any or all of the sides of the formable material.
- the barrier layers 47 , 47 ′ are heat-welded to each other along the lines 49 , which can be continued around the periphery of the formable material, if desired.
- the welding lines 49 pass through the serrations 48 so that, by heat-welding the barrier layers 47 , 47 ′ to each other, the formable member 16 ′ becomes encased within the melted barrier layer material.
- the formable member 16 ′ is firmly anchored within and between the pair of barrier layers 47 , 47 ′. This eliminates the need to glue such elements together.
- a similar result can be achieved for formable materials in sheet form by providing the sheet which serves as the formable material with a series of small holes for alignment with the welding lines 49 .
- the pliable pad of the present invention will generally be flat, or substantially so, either initially or after having been removed and unfolded (or unrolled) from its packaging, or some other storage arrangement.

- a key advantage of this configuration is that the pliable pad can be deployed in a first configuration (e.g., substantially flat or partially folded), to overcome obstacles such as the pipes 73 which would otherwise interfere with the installation of a conventional basin, and then assume a second configuration which is best suited to capture leaking fluid (e.g., a basin formed by desired shaping of the pliable pad, or by shaping the pliable pad to surround the leak).
- the pliable pad of the present invention similarly can be used to accommodate fluids associated with machinery (e.g., coolants, lubricants, and the like).
Abstract
Description
- This invention relates primarily to the fields of wound treatment and surgery, and more particularly, to improvements in the formation of a basin which can be used to collect liquid used in wound irrigation. The present invention can also be used in other fields, including non-medical applications.
- Absorbent pads are routinely used in clinics and in homes. Such pads essentially comprise a combination of an absorbent material and a fluid barrier. A mesh is typically provided over the absorbent material to retain the absorbent material against the fluid barrier, which serves as a backing for the pad.
- For use in irrigating a wound, known absorbent pads have generally been found to be insufficient because unabsorbed, contaminated liquid frequently spills from the periphery of the pad. The spilled liquid constitutes a safety hazard and a health hazard, and frequently requires corrective action.
- To overcome these and other problems associate with known absorbent pads, the present invention provides a pliable pad which can be shaped into a trough or basin (either before use or in situ) for containing excess liquid. In this way, the pliable pad of the present invention can prevent liquid from spilling from the trough or basin which is formed (e.g., onto the floor or onto medical personnel).
- The pliable pad of the present invention can also be used in non-medical applications such as the containment of liquid leaking from a plumbing fixture or from-a machine. This can be especially useful in situations in which a simple pan or bucket cannot be deployed because of limited access, or when such devices would provide inadequate containment of a leak or spray. In such cases, the pliable pad can be used to overcome the problems associated with the use of simple pans or buckets by introducing the pliable pad in one configuration (e.g., flat or partially folded) and by then shaping the pliable pad, in place, to address the problems associated with limited access. In addition, the pliable pad can be shaped to surround the leak, to limit or even eliminate any spray that might otherwise escape.
- In its most basic configuration, the pliable pad of the present invention is comprised of an absorbent material arranged adjacent to a formable material. The absorbent material and/or the formable material can further include a barrier to liquid, or a separate liquid barrier layer can be provided.
- The formable material is preferably chosen so that it can be shaped manually, and so that the desired shape will be retained indefinitely if left undisturbed. The formable material can then be manipulated by hand, or by machine, to form a wall or a series of walls, so that the pliable pad can form a fluid-collecting basin. As examples, the pliable pad can be made formable by mating the absorbent material with a sheet formed of a metal or a metal foil, or by embedding an elongated bendable member (e.g., a wire, rod or tube) within the absorbent material or within a sheet (or sheets) resting upon the absorbent material or to which the absorbent material is attached.
- The resulting structure will then provide an absorbent material located within a basin which is defined by the walls created by manipulating the formable material. Any liquid that is not absorbed by the absorbent-material will nevertheless be retained within the basin, providing added assurances that the fluids in question are effectively collected by the resulting structure.
- The formable material can be pre-formed to facilitate subsequent manipulation by the user into a basin-like shape. Corners and/or edges of the formable material can be attached, by being creased, mechanically fastened or bonded together, for example, using an adhesive or by welding, to further facilitate manipulation by the user. Edges of the formable material can also be folded to permit expansion of the structure to various sizes by the user.
- The formable material, either combined with the absorbent material or prior to being combined with the absorbent material, can be folded or rolled to create a package size which is desirable for shipping and storage. The absorbent material can be combined with the formable material at any point during manufacture of the pliable pad, or prior to or during subsequent shaping of the formable material by the user. This can occur when the formable material is in a generally planar configuration, when the formable material is in the process of being formed into a desired configuration, or after the formable material has been shaped into its final configuration by the user.
- The formable material, or the liquid barrier, can be provided with an extension formed of a liquid-impervious material which can be folded over the pliable pad. The liquid-impervious material can then be draped over the wound to permit convenient irrigation of the wound while protecting the user from contact with hazardous liquid or spray. The liquid-impervious material is preferably, but not necessarily, transparent to further facilitate the procedure to be performed.
- A draining conduit or port can also be provided, if desired, to conduct excess liquid to a separate or external receptacle. Alternatively, a portion of the formable material can itself be shaped to create a draining conduit.
- The pliable pad of the present invention can further include one or more tabs attached to the pliable pad, one purpose of which is to provide a means for securing the pliable pad to the patient (or to a desired structure). The tabs can either be tied to each other, or fastened together by other means. The tabs can assist in supporting the walls which have been formed in their desired position, and can also provide a means for sealing the pliable pad against a patient (or to a desired structure) so that the likelihood of a leakage of liquid is reduced.
- The pliable pad of the present invention will generally include a layer (or section) formed of an absorbent material, which can include a permeable material that allows fluid to pass to the absorbent material without allowing the absorbent material to be released. The layer (or section) of absorbent material and the formable material can be joined together by an adhesive, by heat sealing, or by other means. Alternatively, the layer (or section) of absorbent material can be mechanically attached to the formable material (e.g., by bending over edges of the formable material to capture the layer (or section) of absorbent material) without the use of an adhesive. Another alternative is to simply locate the layer (or section) of absorbent material adjacent to the formable material, without being bonded to the formable material. Yet another alternative is to sandwich the formable material between a pair of sheets, with at least one of the sheets comprising a liquid barrier, if needed. The sheets can be heat welded to each other, or attached with an adhesive, to encase the formable material between the pair of sheets.
- The present invention is also directed to various uses for the pliable pad. The primary use for the pliable pad is in irrigating wounds. To this end, the head or a limb of a patient is placed on a pliable pad which is manipulated to form a basin to contain the appendage. The desired irrigation step is then performed. During such irrigation, liquid is capable of being absorbed by the absorbent material, and any liquid that is not absorbed by the absorbent material is collected in the basin defined by the pliable pad.
- The pliable pad of the present invention also has uses in fields other than medicine. For example, the pliable pad can be used to collect water leaking from plumbing fixtures, such as sinks, or to collect liquids that drain or leak from machinery. Any of a variety of uses are possible.

- FIG. 1 shows a basic embodiment of the pliable pad of the present invention. As used in this specification, the term “pliable pad” refers to the entire composite structure described below.
- The
pliable pad 1 generally includes acenter section 2 which is combined with abacking layer 3. Thecenter section 2 is comprised of an absorbent material, which can be formed of a superabsorbent polymer, an absorbent fabric, a pulp material, cotton or the like, or any other material capable of absorbing liquids. Thebacking layer 3 preferably forms a liquid barrier, and can be formed of one or a plurality of layers formed of selected liquid-retaining materials (which may be the same or different from one another). Preferred liquid-retaining materials can include any of a variety of plastic sheet materials or plastic coatings, with particularly preferred materials for developing the liquid barrier including plastic films formed of vinyl, polyethylene, polypropylene or some other equivalent plastic. - Either the
center section 2 or thebacking layer 3, or both, includes a “formable material” which, as used in this specification, will refer to any material which is capable of assuming a desired shape and of retaining the desired shape which has been assumed. Preferred examples of such formable materials include thin sheets of aluminum or aluminum foil, metal wires, rods or bands, or other structurally equivalent materials. The formable material can be provided in a smooth condition, or can be crinkled or dimpled to increase its strength, as desired. Any of a variety of structurally formable materials can be used, provided the selected material is bendable and can retain its shape after being formed into a particular configuration. - The selected formable material can be implemented as a single layer, as plural layers, or as a composite which includes the formable material. A preferred, composite formable material for use in accordance with the present invention is comprised of two layers of foil separated by a plastic film or coating between the foil layers to reduce the likelihood of leaks through any holes which might come to be formed in the foil layers. The formable material is preferably capable of bending in virtually any direction, for formation into an unlimited variety of shapes.
- In the embodiment shown in FIG. 1, the area of the
backing layer 3 is greater than that of thecenter section 2. For such a configuration, thecenter section 2 is preferably comprised of the absorbent material and thebacking layer 3 is preferably comprised of the formable material. However, thepliable pad 1 of the present invention is not limited to such an arrangement. For example, in configurations where thecenter section 2 is substantially coextensive with thebacking layer 3, thecenter section 2 can include the formable material together with the absorbent material. In such cases, when the pad is formed into a basin, the absorbent material will cover the walls of the basin, as well as the bottom. - FIG. 2 shows a cross-section of the
pliable pad 1 shown in FIG. 1. The illustrated cross-section again includes both thecenter section 2 and thebacking layer 3 of FIG. 1. Thecenter section 2 includes alayer 4 formed of the absorbent material, which is surrounded with and enclosed by an outer layer 5 (including top 6,bottom 7 andside 8 portions), encasing the layer ofabsorbent material 4. The primary purpose of theouter layer 5 is to allow fluid to pass through, to the absorbent material, while preventing particles or fibers of the absorbent material from being released into an open wound. A secondary purpose of theouter layer 5 is to provide a means for reliably locating the layer ofabsorbent material 4 relative to thebacking layer 3, by securing thelayer 4 to thelayer 3 when deemed appropriate. - For some applications, such as in an operating room, the
outer layer 5 may not provide sufficient protection against the release of dust particles from the absorbent material. In such cases, the absorbent material can be formed of a material such as absorbent gauze or superabsorbent fibers, which tend not to release particles. Theouter layer 5 can be omitted in such cases, or retained, as preferred. - The
outer layer 5 will typically be formed of a mesh, non-woven, or equivalent material capable of allowing fluid to pass through theouter layer 5 and to the layer ofabsorbent material 4 contained by theouter layer 5. Theouter layer 5 will preferably completely encase the layer ofabsorbent material 4, and either can simply rest on the layer ofabsorbent material 4 or can be attached to the layer ofabsorbent material 4 using, for example, an adhesive, heat welds, or another equivalent fastening means. Alternatively, thebottom 7 of theouter layer 5 can be omitted and thesides 8 of theouter layer 5 can be attached to thebacking layer 3. - The
outer layer 5 can be comprised either entirely of one material, such as a mesh, or can be constructed from a combination of mesh-like and liquid-impervious materials. A particularly preferred embodiment uses a mesh material for thesides 8 and a liquid-impervious material for the top 6, with the bottom 7 either being omitted, made of a liquid-impervious material or made of a mesh material. In this arrangement, the liquid-impervious material positioned along thetop 6 of theouter layer 5 serves to keep a body part being treated from resting in a direct fluid path with the absorbent material. Fluid is then allowed to flow over the facing defined by thetop 6 of theouter layer 5, and through the mesh forming thesides 8 of theouter layer 5 to the layer ofabsorbent material 4, in this way limiting the amount of fluid that the appendage contacts directly. - In cases where the
outer layer 5 is constructed from a combination of mesh-like and liquid-impervious materials, theouter layer 5 can be implemented either as a single layer, with the liquid-impervious material provided along the top 6 joined at its edges to the mesh layer along one or more of thesides 8 of theouter layer 5, or as plural sections or multiple layers of material. For example, the mesh material can encase the entire layer ofabsorbent material 4, with sections of liquid-impervious material forming a second layer on top of or beneath the mesh material along the top 6 and/or thebottom 7 of theouter layer 5, so that only the sides 8 (and possibly the bottom 7) allow fluid to reach the layer ofabsorbent material 4. Alternatively, and as mentioned previously, theouter layer 5 can be eliminated if preferred. It is also possible to provide only atop portion 6 which is formed of the liquid-impervious material, and to omit thebottom 7 and thesides 8 of theouter layer 5, if desired for a particular application. - FIGS. 3A to3D show cross-sectional views of several alternative configurations for a
formable backing layer 3 for thepliable pad 1 shown in FIG. 1. In FIG. 3A, aliquid barrier layer 9 and a layer offormable material 10 jointly comprise theformable backing layer 3. In this configuration, the formable material alone generally will not provide a sufficient liquid barrier, and the use of an additionalliquid barrier layer 9 is generally preferred in such cases. Theliquid barrier layer 9 is typically comprised of a plastic sheet, film or coating, and can be deployed above and/or below the layer offormable material 10, as is shown in FIGS. 3B and 3A, respectively. The arrangement of FIG. 3B would be suitable, for example, in cases where the formable material is implemented as a wire mesh (e.g., using a soft “chicken wire”), which will tend to retain its shape, but which will not serve as a liquid barrier. Theliquid barrier layer 9 can be deployed as a single layer, or in multiple layers if preferred. - FIG. 3C illustrates an embodiment which employs two
layers liquid barrier layers formable material 10. Aliquid barrier layer 9 can also be positioned betweenmultiple layers - FIG. 4A shows an alternative embodiment for the pliable pad (1′) which is similar to the
pliable pad 1 of FIG. 1, except for the thickness and the surface area of the layer ofabsorbent material 4′. The thickened layer ofabsorbent material 4′ shown in FIG. 4A is primarily used to support an appendage above the liquid level (i.e., above any contaminated fluid which has collected in the basin) during irrigation. Providing a relatively thick layer ofabsorbent material 4′ also serves to concentrate the absorbent material where most of the liquid will tend to gather. - As examples, the thickness of the layer of
absorbent material 4 in the embodiment of FIGS. 1 and 2 can be in the range of from about ⅛ to about ¼ inches, while the thickness of the layer ofabsorbent material 4′ in the embodiment of FIG. 4A can be in the range of from about 1 to about 2 inches. This results in a layer of absorbent material for the embodiment shown in FIG. 4A which can be on the order of as much as 16 times the thickness of the layer of absorbent material for the embodiment shown in FIG. 1. Such thicknesses are presently considered preferred. However, other thicknesses can freely be used if preferred for a given application. - The thickness selected for the layer of absorbent material can be developed either with a single layer of material, or in multiple layers, as preferred. Multiple layer thicknesses can be developed using plural, discrete layers of absorbent material, or by folding a layer of absorbent material into multiple layers to form a pillow shaped structure.
- FIGS. 4B to4D show alternative embodiments for the pliable pad, each having a
support 11 which can be used to lift an appendage or other object, primarily for purposes of raising the appendage or the other object above the predominant fluid collecting surfaces of the pliable pad. In FIG. 4B, thesupport 11 is located on top of the center section 2 (which is formed of the layer of absorbent material 4) of thepliable pad 1. In FIG. 4C, thesupport 11 is placed directly on top of thebacking layer 3 of thepliable pad 12, and a pair ofmembers 13 formed of the absorbent material are positioned on opposite sides of thesupport 11. Equivalent arrangements, includingplural supports 11 and/orplural members 13 formed of the absorbent material placed at various locations on thebacking layer 3, are also possible. - A support can also be positioned beneath the layer of absorbent material so that the absorbent material extends beyond the sides of the support, as well as over the top surface of the support. As a further alternative, the support can be positioned beneath the backing layer. For example, FIG. 4D shows an alternative embodiment for the pliable pad (14) which has a
support 11 positioned between twolayers 9 formed of a liquid barrier material, which combine to develop thebacking layer 3 for thepliable pad 14, combined with a pair ofmembers 13 formed of the absorbent material. Again, other arrangements including thesupport 11, either as part of or beneath thebacking layer 3, can also be developed. - FIG. 5A shows an alternative embodiment for the pliable pad (15) having an elongate bendable member 16 (e.g., a wire, rod or tube) which is combined with the layer of
absorbent material 4 to serve as a formable material. In this embodiment, the layer ofabsorbent material 4 is made formable by the stiffening effect of themember 16 which is mated with the layer ofabsorbent material 4. Since the layer ofabsorbent material 4 is not normally also a liquid barrier, the layer of absorbent material can also be combined with one or more separate layers formed of a liquid barrier material, if desired. - In FIG. 5A, the
member 16 is formed in a serpentine pattern. FIG. 5B shows an alternative embodiment similar to that of FIG. 5A, except that themember 16′ is configured in an undulating pattern, near the periphery of thepliable pad 15′. As in the embodiment of FIG. 5A, thepliable pad 15′ is made formable by thebendable member 16′. - FIG. 6 shows an alternative embodiment for the pliable pad (17) which includes a
formable backing layer 18 comprised of a formable material having acutout portion 19, the primary purpose of which is to reduce the cost of manufacture. For convenience of illustration, the layer of absorbent material which would ordinarily be combined with theformable backing layer 18 has not been shown in FIG. 6. Theformable backing layer 18 preferably includes aliquid barrier layer 20, which can be positioned above (as shown by the dotted outline in FIG. 6) and/or below theformable backing layer 18, as desired for a particular application. - In the embodiment shown in FIG. 6, the
cutout portion 19 is generally square or rectangular in shape and is located near the center of the pliable pad. The cutout portion is preferably located at or near the center of the pliable pad because in this region, the strength of the formable material is less critical, primarily because the center portion will normally remain flat, even after the formable material has been shaped to form a basin. Other configurations for the cutout region are equally possible. For example, more than one cutout portion can be provided, and the shape of the cutout portion or portions provided can be varied considerably. Complex patterns can also be developed, if desired for a particular application, such as the combination of a plurality of cutout regions to form a “checkerboard” pattern having squares of material alternating with gaps formed of the plural cutout regions. - FIG. 7 shows an alternative embodiment for the pliable pad (21) which includes a
spray barrier 22 protruding from aside edge 23 of the pad, in this case extending from aside edge 23 of thebacking layer 3. Thespray barrier 22 is preferably comprised of a clear sheet of plastic material, but can also be formed of a translucent or opaque material which is substantially impervious to liquids. Thespray barrier 22 can either be provided as an extension of one of theliquid barrier layers formable material - The
spray barrier 22 is used to provide a sheet which can be folded over the patient to form a cover for protecting the user of the pliable pad when spraying fluids within a formed basin. For example, FIG. 8 illustrates use of thepliable pad 21 with a hand-heldspray gun 24 which is manipulated underneath thespray barrier 22. Thespray barrier 22 prevents liquid issuing from thespray gun 24 from coming into contact with the user. - FIG. 9 shows an alternative embodiment for the pliable pad (25), which in this case has already been formed into a basin, and which further includes a
drainage port 26. Ahose 27 is optionally provided for connection to thedrainage port 26, which in this case is implemented as a flange for receiving thehose 27. Theport 26 receives fluid collected within the basin formed by the foldedpliable pad 25, for conducting the received fluid from the basin to a suitable receptacle, such as thebucket 28. Use of the flanged connection shown in FIG. 9 is preferred so that the drainage port 26 (and any hose it receives) is reliably sealed against thepliable pad 25 to prevent leakage. Multiple drainage ports can also be used, if desired, to provide the pliable pad with plural drains (e.g., along the side or at the bottom of the pad). - FIG. 10 shows portions (i.e., the corner29) of an alternative embodiment for the pliable pad (30) having a layer of
formable material 31 which is comprised of paper or stiff cardboard. The paper or stiff cardboard material can then be scored, at 32, so that the resulting backing layer can be more easily shaped (e.g., to form the box-like configuration shown). - FIG. 11 shows an alternative embodiment for the pliable pad (33) which includes a pair of
tabs 34 which are formed as extensions of aformable backing layer 35. Such tabs can similarly extend from other portions of the pliable pad, if desired. Thetabs 34 are preferably comprised of a plastic material, and can be manufactured to develop any of a variety of different configurations. The configuration shown in FIG. 11 is useful for conserving material, and as a result, reducing the costs of fabrication. It is also possible to form tabs which extend from plural positions on the pliable pad (e.g., from opposing peripheral edges of the formable backing layer), if desired. - In use, the
tabs 34 can simply be tied together to secure thepliable pad 33 against the limb of a patient. As an alternative, one or more of thetabs 34 can be provided with anadhesive strip 36 for facilitating connection of thetabs 34 to one another. Any of a variety of fasteners can be used to achieve a similar result, such as a hook-and-loop arrangement or some other mechanical fastener, so that thetabs 34 can be conveniently secured to each other. FIG. 12 illustrates the use oftabs 34 having theadhesive strips 36 of FIG. 11 to secure alimb 37 within a definedbasin 38. The primary purpose of thetabs 34 is to secure thepliable pad 33 against the patient and create a seal to further prevent the leakage of liquid, and to secure thelimb 37 of the patient to thepliable pad 33. - FIG. 13 shows an alternative embodiment for the pliable pad (39) which again includes a layer of
formable material 40, a layer ofabsorbent material 41 and a liquid barrier layer 42 (which is optionally provided). In this embodiment, the formable material is a metal foil and the liquid barrier (if used) is a plastic film. The layer ofabsorbent material 41 is attached to the plastic film forming theliquid barrier layer 42. Theedges 43 of the foil which develops the layer offormable material 40 are folded around the corresponding edges of the plastic film which develops theliquid barrier layer 42, if used, or are folded to directly engage the layer ofabsorbent material 41. Folding the foil layer in this manner eliminates the need to glue or otherwise attach thefoil layer 40 to the layer ofabsorbent material 41, or to theliquid barrier layer 42, if used. - FIGS.14 to 17 illustrate the various stages of an assembly procedure which can be used to eliminate the need to affix a layer of
formable material 40 to other portions of the pliable pad, in this case, a layer ofabsorbent material 41. In FIG. 14, the layer of absorbent material 41 (with or without a netting, or some other outer layer) is positioned over a backing layer which includes the layer offormable material 40. Thelayers formable material 40 have been bent over the layer ofabsorbent material 41. Following this, thesides 45 of the layer offormable material 40 are bent over, as shown in FIG. 16. The completed (folded) product is shown in FIG. 17. For added strength, the ends and sides of the sheet offormable material 40 can be bent over several times. In any event, the resulting arrangement operates to capture the layer ofabsorbent material 41 within a frame formed of bent aluminum or aluminum foil, eliminating the need for an adhesive to keep the assembly in place. - FIG. 18 shows an alternative embodiment for the pliable pad (46) having a pair of barrier layers 47, 47′ which are heat-welded to the formable material (implemented as the
member 16′ of FIG. 5B). In this configuration, the pair of barrier layers 47, 47′ surround theformable member 16′, which is shown in phantom because it will then be sandwiched between the pair of barrier layers 47, 47′. The undulating formable material serves to developserrated edges 48 which, for convenience of illustration, are shown only on two sides. In practice, such serrations can be established on any or all of the sides of the formable material. The barrier layers 47, 47′ are heat-welded to each other along thelines 49, which can be continued around the periphery of the formable material, if desired. The welding lines 49 pass through theserrations 48 so that, by heat-welding the barrier layers 47, 47′ to each other, theformable member 16′ becomes encased within the melted barrier layer material. As a result, theformable member 16′ is firmly anchored within and between the pair of barrier layers 47, 47′. This eliminates the need to glue such elements together. A similar result can be achieved for formable materials in sheet form by providing the sheet which serves as the formable material with a series of small holes for alignment with the welding lines 49. - Prior to use, the pliable pad of the present invention will generally be flat, or substantially so, either initially or after having been removed and unfolded (or unrolled) from its packaging, or some other storage arrangement. The pliable pad can also be generally pillow shaped, either as packaged, for convenience of storage, or resulting from shaping performed by the user. Deployment of the pliable pad will vary, responsive to the desired use for the pliable pad.
- FIG. 19 illustrates the initial formation of a typical pliable pad, which is being shaped by the
hands 50 of a user to form abasin 51. FIG. 20 shows the shapedbasin 51, after having been formed. - FIG. 21 shows an alternative embodiment for the pliable pad (52) having
seams 53 which are preferably positioned at each of thecorners 54 of thepliable pad 52, and which are fixed to facilitate deployment of thepliable pad 52 from a generally flat configuration into a basin-like structure. Theseams 53 can be developed by folding (e.g., crimping or creasing) portions of the layer offormable material 55, or by fixing portions of the layer offormable material 55 together using suitable means (e.g., using mechanical fasteners or by bonding, for example, using an adhesive or by welding). - FIG. 22 shows deployment of the
pliable pad 52 shown in FIG. 21. As the center section of thepliable pad 52 is opened, for example, by engaging thepanels 56 of thepliable pad 52, the regions including theseams 53 will automatically develop the corners of abasin 57, serving to support the wall-like structures of thebasin 57 as the user pulls back on thesides 56, opening the center section which will form thebasin 57, and creating end-walls 58 for the resultingbasin 57. - FIG. 23 shows an alternative embodiment for the pliable pad (59) which, in addition to the
seams 53 of thepliable pad 52, includespre-folded gussets 60 formed along opposing lateral edges 61. Thegussets 60 permit further expansion of the resulting structure to permit adjustment of the size of the basin which is formed. - FIG. 24 shows deployment of the
pliable pad 59 shown in FIG. 23. As the user pulls back on thesides 56, theseams 53 will automatically develop the corners of abasin 57′, serving to open the center section which will form thebasin 57′ and creating the end-walls 58′ for the resultingbasin 57′. As is further illustrated in FIG. 25,expandable walls 62 are developed in the layer of formable material by thepre-folded gussets 60, allowing the user to increase the height of the walls forming thebasin 57′ by pulling on thesides 56, and expanding the folds forming thegussets 60. Thegussets 60 can be formed with single or multiple folds, as desired. - FIG. 26 illustrates use of the pliable pad of the present invention to develop a typical configuration useful for irrigating a
forearm 63. To this end, theforearm 63 is placed on the pliable pad, which can either be pre-formed to develop thebasin 64 for accommodating theforearm 63, or which can initially be deployed flat (or substantially flat) and then formed around theforearm 63. In either case, the resultingbasin 64 which is defined by the pliable pad is made ready to receive water, or some other irrigation fluid. FIG. 27 illustrates a similar configuration for use in irrigating aleg 65. FIG. 28 shows use of the pliable pad for irrigating a patient's head 66 (e.g., to treat an eye or other head wound). - FIG. 29 again shows use of the pliable pad of the present invention, following its formation into a
basin 67, to surround the patient'shead 66. In this case, portions of the pliable pad have been formed into adrainage channel 68 for directing liquid into a desiredreceptacle 69. This embodiment provides an alternative to the embodiment shown in FIG. 9, which uses the additional structures of ahose 27 andflange 26 which are not originally part of the pliable pad, to achieve a similar result. In the embodiment of FIG. 29, a portion of the pliable pad itself develops the drain, eliminating the need to provide additional structures for such purposes. - The pliable pad of the present invention can also used to perform a variety of non-medical applications. As an example, FIG. 30 shows use of the pliable pad to develop a fluid-receiving
receptacle 70 which can be positioned under asink 71. The formedreceptacle 70 includes a layer ofabsorbent material 72 which serves to soak up liquid that may leak from thepipes 73. Thebasin 74 which is defined by the formable material associated with thereceptacle 70 serves to contain received liquid, for subsequent collection and removal. A key advantage of this configuration is that the pliable pad can be deployed in a first configuration (e.g., substantially flat or partially folded), to overcome obstacles such as thepipes 73 which would otherwise interfere with the installation of a conventional basin, and then assume a second configuration which is best suited to capture leaking fluid (e.g., a basin formed by desired shaping of the pliable pad, or by shaping the pliable pad to surround the leak). The pliable pad of the present invention similarly can be used to accommodate fluids associated with machinery (e.g., coolants, lubricants, and the like). - It will therefore be understood that various changes in the details, materials and arrangement of parts which have been herein described and illustrated in order to explain the nature of this invention may be made by those skilled in the art within the principle and scope of the invention as expressed in the following claims.
