Qyon Newsom BY 1! MM Patented Oct. 19, 1954 uulrso QFFICE 1 Claim.

This invention relates to haemostats, or packs as used for the treatment of bleeding from the nose, and it has reference more particularly to improvements in such devices that employ inflatable rubber bags which are designed for insertion into the nasal cavities.

It is the principal object of the present invention to provide a haemosta-t of the inflatable bag type that is exceedingly simple in construction; that is relatively inexpensive; that be applied with safety by an inexperienced person and which will efiectively and satisfactorily accomplish its intended purpose.

It is also an object of this invention to provide a device for treatment of hemostasis wherein the inflatable rubber bag is adapted to be inserted into the nasal passage, or cavity, and is equipped with an inflating tube of a semi-soft rubber, extended within the bag to substantially its full length, and which can be safely employed for the insertion of the bag to proper position before it is inflated.

It is also an important object of this invention to provide a simple and effective device for treating nose bleed, that is of such inexpensive construction that it is practical and economical to discard it after its first use instead of cleaning and sterilizing it for subsequent use. More pa:- ticularly, the present device is designed use as a first aid instrument and is not oi that category designated as surgical instruments.

Yet another object of the present invention is to provide a haemostat that comprises only three parts, namely, the inflatable rubber beg, the bag filling and inserting tube and an inflating bulb connected with the latter; all parts being assemled as an integral unit that can be easily sterilized, and then kept in a sterile container for its one use; after which it is discarded.

Still further objects and advantages of the invention. reside in the details of construction of the parts embodied therein; in the relationshi of parts as assembled, and in the mode of use of the device as will hereinafter be fully described.

In accomplishing the above mentioned and other objects of the invention, I have provided the improved details of construction, the pre ierred forms of which are illustrated in the sccornpanying drawings, whereinl is a side view of the haemostat of the present invention.

Fig. 2 is a somewhat enlarged longitudinal section of the inflatable bag portion of the device,

showing the extent to which the inflating tube extends thereinto.

Fig. 3 is a view illustrating application and use of the device.

With the understanding that the present device is intended to be so made as to permit it to be safely applied for use by inexperienced persons, and also to be suiiiciently inexpensive that it becomes economical and practical to discard it after being once used, I have constructed the present device entirely of rubber.

It will be explained here that there are devices for the present purpose of various kinds, and makes new on the market and in use that employ inflatable bags, equipped with various forms of expensive and complicated inflating means. Most of the present day devices are of the surgical instrument class and are not designed as first aid equipment and are too expensive to be economically disposed of after their first use. No prior device,'-to my knowledge, employs a semi-rigid inflating tube that is so related to the bag that it can be employed as a means for the inserting of the bag into the nasal passage with safety, either by an inexperienced or an experienced person.

Referring more in detail to the drawings- In ig. 'l, l have shown the device of this invention in its present preferred construction. It comprises an elongated, inflatable rubber bag it into which an inflating tube ii of relatively mall diameter is extended. As well shown in ig. 2, the tube 52 extends substantially the full ength of the bag, and the neck or mouth of the bag is. vulcanized to the tube or otherwise sealed thereto in an air tight connection, as indicated at it. The bag is of thin, soft rubber, similar to that of the well known toy balloon.

The inflating tube It extends a few inches outside the bag it: and is equipped at end with a compressible rubber bulb i5 with a single air inlet hole is on one side. The bulb is resilient and expands to full position as shown in Fig. 1 upon release of compressing pressure thereon. To inflate the bag it, it is only required that air be forced thereinto by squeezing the bulb. While collapsing pressure is being applied to the bulb, the hole It is covered by the hand or a finger, then while holding the bulb compresse the filling tube is pinched tightly closed to re air in the bag while the bulb is permitted to expand and fill with air. Then the compressing of the bulb is repeated. A suitable spring clip ll, of metal or other suitable material, may be applied to the tube it as seen in Fig. 3 to retain lized at time of manufacture and kept in a sterile container until time of use.

For treatment of nose bleed, the device is used. in the manner illustrated in Fig. 3. The bag It! is put in place in the nasal passage by use of the tube 12 which is soft and flexible but having suflicient rigidity to enable it to be pushed endwise into the nostril, and to advance the collapsed bag with it to place of use. When the bag is in place, it is then inflated as previously explained by means of bulb I to pack the cavity for the intended purpose; air being retained in the inflated bag merely by the pinching together of the tube by hand or by means of the clip I! as applied thereto in Fig. 1.

When there is no further need for it, the device is deflated and drawn out of the nasal cavity. It can economically be discarded rather than cleansed and sterilized for a second use.

While the size of parts is of no particular significance it Will be here explained that for its present intended use the bag [9 should be about 2 inches long. The inflating tube is about ,4 in diameter and is blunt at its inner end and extends outwardly about three inches beyond the sealed connection with the bag. The bulb is relatively small, to enable the device to be easily held and used.

To summarize the advantages of the present device it can be said that it can be easily and readily applied by skilled or unskilled persons alike; it readily conforms to the cavity in which it is enclosed regardless of the shape of that cavity; it is entirely satisfactory and effective for its intended uses and mode of application; it is comparatively inexpensive as it comprises no expensive or complicated parts; easily sterilized for use and retained for use in a sterile container; its inexpensiveness make it economically practical to dispose of it after once being used, thus to eliminate the usual requirement of cleansing and sterilizing for subsequent use; it is a single, one piece, one material device, characterized by use of an inflating tube that can be effectively and safely used as a means for inserting the collapsible bag in the cavity to be packed.

Having thus described my invention, what I claim as new therein and desire to: secure by Letters Patent is:

A device of the character described comprising an elongate, collapsible and inflatable bag of elastic, air tight material, a flexible tube open at both ends and having one end extended into the bag through its opening in an air sealed joint and continuing lengthwise of the bag to substantially its full length but short of the outer end of the bag, a hand compressible air bulb applied to the other end of the tube and operable for effecting forced injection of air therefrom through the tube and into the bag for its inflation; an air hole in the bulb to permit intake and discharge of air therefrom; said tube being of relatively small diameter and of such rigidity that it is operable as a means for projecting the deflated bag into the nasal cavity and a part of the tube between the bulb and bag exposed as a finger gripping portion for the projecting of the bag and tube into the nasal cavity and to which a clip means is applied to retain inflating air in the bag.
