Description

protection time

Technical area

The invention relates to a protective tent for protecting the environment from bacteria when treating highly infectious wounds, consisting of a splash-proof tarpaulin with at least one transparent area for visually controlling the treatment curtain and having two openings for engaging the hands of a treating person.

State of the art

In medical applications, especially when cleaning wounds, transparent tarpaulins are used to protect the environment, the patient, and the treating person from the bacteria of the wounds. In wound cleaning, the wounds are rinsed with a jet of a solution of a suitable device and collected the spray water with compresses as well as possible. Such protective tents mentioned above are already in use.

The body part to be treated is placed under a tarpaulin for this purpose, which is usually suspended centrally on a corresponding device in order to create a desired space in the form of a protective tent.

The treating person puts on a protective suit and protective gloves and finally reaches into the two openings of the tarpaulin to perform the treatment. The disadvantage of this method is on the one hand the awkward cladding of the person treating, on the other hand, the lack of protection, as the - O __

Bacteria naturally can get into the environment through the two hand openings. In addition, the bacteria on the gloves and on the protective clothing are brought into the environment after the end of the treatment, for example on control knobs of treatment devices, as soon as the hands are removed from the openings.

Today veterinary gloves are sometimes used in such tents, which are inserted loosely into the hand openings. A disadvantage of this solution is the hatching out of the veterinary gloves, which is not very easy. In addition, bacteria can also reach the outside world through the hand openings.

A protective tent from GB1436104 provides a series of pointed projections that can be pierced by instruments as needed, as well as extensions configured as gloves for the intervention of a treating person.

The US 4335712 also has openings for instruments or extensions for or with gloves on.

GB1604033 and US 4950222 disclose protective tents that protect the patient from bacteria by a permanent overpressure under the tent, but not the environment of the patient's bacteria. The first font provides gloves for the treating person and openings for insertion of instruments, the second font only openings for intervention. Presentation of the invention

Object of the present invention is to provide a shelter tent of the kind mentioned, on the one hand ensures maximum possible hygiene, on the other hand is comfortable for the person to be treated at work.

The object is solved by the characteristics of the independent patent claim.

The idea on which the invention is based is that a watertight, robust, flexible sleeve is attached tightly at the edge of each opening, the size and shape of which allow an entire hand to be comfortably and quickly inserted up to its end without spreading the fingers. and can be executed.

Ways to carry out the invention

Fig. 1 shows a photograph of a protective tent 1 according to the prior art in the application. The body part of a patient with a wound 5 to be treated is to be seen under a tarpaulin 6, which represents the protective tent. In this case, the body part is a leg. The tarpaulin 6 has a transparent area 7, through which a treating person has a clear view of the area of the patient to be treated. The tarpaulin also has two openings 8, through which the treating person can intervene with their hands 9. Gloves are worn for protection against the bacteria. With a treatment instrument 13, which is guided below the tarpaulin in the interior of the protective tent 1, the treatment can take place. In this case, the wound is cleaned with a high pressure water jet. The lower edge of the protective tent is placed under a flowing layer on which the body part lies in order to close the lower access of the protective tent as well as possible. Fig. 2 shows a protective tent 1 according to the prior art, suspended on a dedicated erection device 2 in order to achieve a tent effect.

The protective tent essentially comprises a tarpaulin 6 which, for example, is made into a tent shape with seams 3. Variants for this are also possible. The protective tent 1 has a lower access 4. For treatment, the body part to be treated is brought into the protective tent 1 through this access 4. The tarpaulin has a transparent area 7 through which the treating person can visually control the treatment. In addition, two openings 8 are attached to the tarpaulin 6, through which the treating person receives access to the treatment site with one hand. Beforehand, gloves are put on. In addition, protective clothing is necessary.

Fig. 3 shows the same device of the protective tent 1 according to the prior art, wherein in the two openings 8 hands of a treating person with veterinary gloves 10 are introduced. Such gloves 10 are cumbersome to put on and take off. They may be separate from or attached to the shelter.

In both devices according to FIGS. 2 and 3, there is still a risk of infection due to released germs from the wound. In addition, during a treatment every now and then a controller of a device must be operated, which is a withdrawal of the Hansschuh resp. Veterinary gloves 10 required. This is cumbersome on the one hand, on the other hand, this also increases the risk that bacteria enter the environment.

Fig. 4 shows the same arrangement as Figs. 2 and 3, but in this inventive protective tent 1 at the edge 11 of each opening 8 for the hands a waterproof, robust, flexible

Case 12 tightly attached. The size and shape of this case 12 allows an entire hand to be easily and quickly inserted and deployed without spreading the fingers to their end.

An inserted hand can now be spread in the end area. This is necessary to grab and hold the necessary utensils for a treatment. Other fine motor movements need not be made for such treatment.

By the dense attachment of the shell 12 ensures that no germs can pass from the interior of the protective tent 1 in the environment. The shape and size of the casings 12 ensure that the person treating them has their hands free within a very short time for other operations, be it for operating a device, for procuring further aids or for other actions.

The case must be so strong that it can not easily be damaged by fingernails or edgy devices, but so flexible that handling through this case will not cause any problems.

The overall length of the sheath 12 should preferably be about mid-forearm to fingertips of an adult, the width about that of a splayed hand.

A minimum width of the sheath 12 to the end portion 19 is 16 cm when treating persons with small hands. Otherwise, minimum widths of 20 cm are preferable. The shells should not be too wide, so as not to have too much disturbing material around the hands. Maximum widths of 25-30 cm should preferably not be exceeded. In a preferred embodiment, the tarpaulin 6 is provided on its inside with a saufähigen flow 16 except in the transparent area. This absorbs spilling liquid that bounces off wounds when cleaning. The flow prevents the liquid from dripping down the tarpaulin 6 and at most can escape from the protective tent 1. In addition, it prevents sticking of the tarpaulin 6 with itself, with the hand area or with a treatment instrument and gives the tarpaulin 6 a certain rigidity, as a result of which the size of the interior of the protective tent 1 is better ensured.

The surface of the fleece is so large that a saturation of the absorption capacity is not achieved, even during long treatments, and the adhesion through surface wetting can have an effect over the entire treatment time. This adhesion acts as a driving force, which binds the water-bound germs to the fibers of the fleece. The small droplets, charged with germs, are quickly absorbed by the fleece and caught. As the amount of water in the fleece increases, the water-permeated surface is widened and the adhesion effect accelerated. As a result, the view through the transparent area 7 remains well ensured. The degree of water saturation of the fleece is not reached even in long treatments in which up to 500 ml of water are consumed.

6 shows an alternative embodiment of a protective tent 1 according to the invention. In this arrangement, each casing 12 has two regions 15 which are slightly separated by a recess 14 and which are suitable for separating the thumb and the other fingers of one hand into the two regions 15 to lead. This has the advantage that the handling is again somewhat easier, but without having to insert each finger individually into a member of a glove 10. The indentation 14 should preferably correspond approximately to the shape of a hand between thumb and forefinger in the spread state. Sheaths 12 formed in this way allow a perfect working with a treatment instrument. The handling is completely sufficient for the treatment of wounds.

Fig. 5 shows various embodiments of casings 12 in their end regions 19. Fig. 5a shows the simplest and cheapest form of an inventive shell 12. This shell 12 terminates in a straight line. In Fig. 5b, the shell 12 also terminates in a straight line, but this is not perpendicular to the longitudinal direction of the shell 12 is mounted in contrast to that in Fig. 5a but obliquely thereto. These sheaths 12 should be attached to the openings 8 so that one person's thumbs can be conveniently brought into the obtuse angle, the other fingers of the hand at the acute angle of the end portion. It has been shown that this variant is also cost-effective for the production, compared to the version in Fig. 5a but much more convenient for gripping objects.

Fig. 5c shows a rounded end portion 19 of the shell 12. Since this shape corresponds approximately to the outline of a spread hand, can be in this case 12 also work well. It has been shown that it is advantageous if at least some of the fingers in the end portion 19 of the shell 12 are at various points when the hand is spread. Because of the friction on the fingertips, in this position the sheath 12 slides less under the fingers when something has to be picked up by the sheath with one hand. This variant is also relatively inexpensive to manufacture. 5 d, e and f show the same end regions 19 of the casings 12 as in FIGS. 5 a, b and c, wherein a constriction or indentation 14 has been created between the outermost ends of the end region 19, for example by means of an adhesive. This results in two by slightly separate areas 15, which are adapted to lead the thumb and the other fingers of a hand in the two areas 15 separately. This has the advantage that the handling is facilitated once again, but without having to insert each finger individually into a link of a glove 10. The indentation 14 should preferably correspond approximately to the shape of a hand between the thumb and forefinger in the spread state. Sheaths 12 formed in this way allow a perfect working with a treatment instrument. The handling is completely sufficient for the treatment of wounds.

This indentation 14 can be mounted centrally or laterally to allow the thumb correspondingly less space than the remaining fingers of one hand.

5g and 5h show two further examples of end regions 19 with indentations 14, these indentations 14 being created directly by the contour of the shell 12 and not by a constriction attached later.

All variants with indentations 14 offer particularly gripping sheaths, because the area of the hand between thumb and index finger can rest against these indentations 14 and thus enables a good guidance of the sheath.

Fig. 6 shows further inventive embodiments of the invention. In a preferred embodiment, the protective tent 1 can have a device 22 for sealing the lower edge of the tarpaulin 6 in the region of the access 4 to a base. This device 22 may in particular be an adhesive or Velcro device. A Velcro device is particularly suitable for attachment to a pad of flow, whereas a self-adhesive strip adhere well, especially on smooth substrates such as plastic surfaces or films.

Preferably, the protective tent 1 has at least one further opening 17, wherein at the edge 11 of this opening 17, a waterproof, robust, flexible sheath 18 is tightly mounted. A treatment instrument 13, for example a handpiece of a high-pressure water jet device, can be introduced into this casing 18. As a result, the treatment instrument 13 does not have to be guided through the lower access 4 into the interior of the protective tent, which in turn better seals the interior.

In a treatment, the end portion 19 of the shell 18, which is not attached to the tarpaulin 6, can be opened at will. By a water jet of the handpiece of a high-pressure water jet device, for example, a required hole can be generated in order to carry out the treatment can. Or, an opening 20 of the sheath in the end region 19 may be generated by cutting or already existing, as shown in FIG. 6. In any case, a device 21 is used to tightly and tightly attach the end portion 19 around the treatment instrument 13 (not shown). This device 21 may in particular comprise an adhesive or Velcro fastener 25 and / or an Elastic.

FIG. 7 shows a further preferred embodiment of the protective tent 1 according to the invention. In this embodiment, the protective tent 1 has two further openings 23, to which also sheaths 12, the same as at the first two openings 8, are tightly mounted for engagement of hands 9 of another person. These openings are preferably tions 23 on the other side of the protective tent 1 with respect to the first two openings 8 mounted to allow the participation of the other person. A second transparent area 24 in the tarpaulin 6 allows the second person to visually inspect the treatment. The two transparent areas can be connected to each other.

Of course, further openings can be provided with covers, optionally for the participation of other persons and / or for the access of other instruments or auxiliary materials.

The protective tent 1 is preferably radiation-resistant to gamma radiation in order to be sterilized. A sterile protective tent 1 according to the invention can also be used in particular in an operating room.

In particular, all the features mentioned here can be combined after being loaded.

The protective tent 1 according to the invention ensures the creation of a dense environment in which medical treatments, in particular the cleaning of wounds, can be carried out, with no bacteria escaping from this environment. In addition, it allows quick and clean access from one or more treating persons as well as devices to the treatment site. The hands can always be removed from the treatment site within a very short time during a treatment and continue to work again at the treatment site in just as short a time, without having to put gloves on and off.

Since the protective tent according to the invention is contaminated after the treatment, it is a disposable product and must be disposed of after use. LIST OF REFERENCE NUMBERS
