Abstract

Adhesive plaster dressing, to hold together the edges of a gaping wound comprises strips (5) of non-stretch material with openings (4) between the adhesive sections (6) to allow blood, fluid and air to pass through. The openings (4) are covered by a replaceable dressing pad (1-3).

Description

The invention relates to a band aid for the seamless adaptation of gaping wound edges with a Strips of non-stretch material outside towards the area of the wound or the wound edges set at least two sides with skin-friendly Adhesive equipped surface parts, the front the adaption is covered with a removable protective film are.

For cuts or lacerations, but also for others Injuries with gaping wound edges are common a seamless wound closure for cosmetic reasons preferable, or is the adaptation of the wound edges by means of elaborate seams not desirable.

In such cases, there are ready-to-use wound dressings end stripes or special so-called clip patch application. After fixing a bracket plasters, however, can still cause blood and exudate occurs. This is a pollution of the order and impairment of the adhesive behavior of the patch possible. There is also infection danger of bacteria and viruses entering the Wound. It is missing in the first phase of blood clotting and wound healing an effective germ barrier to the outside world, which entails the risk of infection of the wound counteracts.

From US-PS 5,158,555 is a protective association for open Known wounds from one at both ends itself equipped with adhesive strips. This is in Area of the wound with comparatively large, so-called macro perforations for sufficient  Ventilation of the wound trained. On its top the association owns in the area of this coarse-pored per foration a removable cover sheet with fine-pored per foration. This may require ventilation of the wound be reduced wisely. On the wound facing The bandage has a gauze in the area of the wound layer, a comparatively thick layer of liquid absorbent material as well as a dehesive equipped protective layer against the wound. With regard to a seamless adaptation of gaping wounds edges is not disclosed in the known document. Furthermore, the capacity to absorb blood and / or Exudate secretions of the wound comparatively be small. Because, moreover, the absorber material on the side of the dressing facing the wound is ordered, this material, after dealing with Body fluid has soaked up, not removed separately become. The entire association must be changed become what is detrimental to interrupting healing process can lead.

The invention has for its object a bracket plasters for the seamless adaptation of gaping wounds to specify margins of the type mentioned at the beginning, which based on the aforementioned prior art avoids associated disadvantages and difficulties and is able to in the first few hours after the patch Supply in large quantities of blood and Record exudate and thereby additionally good wound healing conditions in connection with a Germ barrier, thermal insulation and upholstery create visible touches and pressure, and which offers the possibility of that on the wound attached suction pads on the opposite side of the patch if necessary, remove without loosening the bandage or to switch and thus an uninterrupted healing to promote the process.  

The solution to the problem is achieved with one Brackets of the ge in the preamble of claim 1 named type with the invention in that the bracket plaster strips in the area between those with glue equipped surface parts with for body fluids such as blood and / or exudate secretions as well as for Air permeable breakthroughs is formed to the outside with a wound that can be arranged over it pillows are coverable.

With great advantage is the on the outside of the The intended arrangement of the wound pad has been achieved, that its absorption corresponding to its absorbency Leaking body fluid problem start watching and the wound pad if necessary from Association can be detached and / or renewed without the dressing itself must be removed from the wound. The removal or partial removal of the wound pad it also opens up the possibility of getting the wound through the breakthroughs with one effect if necessary to treat substances such as penicillin or an antibiotic deln.

One embodiment provides that the wound pad is a is independent plaster, the suction pad with a self-adhesive film section as carrier material with a pressure sensitive adhesive coating for separate fixation on the plaster that can be glued to the wound edges strip is formed, and its film section the suction pad protrudes on both sides.

Further expedient configurations are corresponding provided the subclaims.

The invention is illustrated in schematic drawings represents, from the drawings further advantageous Details of the invention can be found. Show it

Figure 1 is a longitudinal section through the staple in the state before use.

FIG. 2 also shows the plaster according to FIG. 1 in longitudinal section with the wound pad adhered to its outside;

Fig. 3 is a perspective view of the plaster during the application of the wound pad.

The patch clamp shown in Fig. 1 comprises a strip 5 made of non-stretchable material, which has outside the area of a wound to be closed on opposite sides of at least two equipped with skin-friendly adhesive surface parts 6. In the state that is still unused, these are releasably covered with a protective film 8 before the adaptation. According to the invention, the strip 5 has , as can be seen from FIG. 3, in the area between the surface parts 6 equipped with adhesive for body fluids such as blood and / or exudate secretions and for openings 4 permeable to air. After adaptation of the staple plaster to a wound, as shown in FIGS . 2 and 3, these are covered on the outside with a wound pad 1 , 2 , 3 which can be arranged above them. According to a preferred embodiment, the wound cushion 1 , 2 , 3 is an independent plaster, the suction pad 1 of which is formed with a self-adhesive film section 2 as a carrier material with a pressure-sensitive adhesive coating 3 for separate fixing on the plaster strip 5 which can be glued to the wound edges, and its film section 2 the suction pad 1 protrudes on both sides.

As the summary of FIGS. 1 to 3 shows, the suction pad 1 has dimensions at least covering the openings 4 . It consists of highly absorbent material and preferably of known wound pad materials and particularly preferably has an antibacterial or antimicrobial finish.

The arrangement of the wound pad 1 , 2 , 3 after adaptation of the plaster on the skin of a patient, it allows the suction pad 1 to be made comparatively thick and thereby to give it a comparatively large liquid absorption capacity.

An expedient embodiment of the staple plaster provides that the self-adhesive film section 2 of the wound pad 1 , 2 , 3 consists of a preferably transparent, water-vapor and air-permeable film material. The same properties are of course also provided for the pressure-sensitive adhesive coating 3 of the film section 2 .

An embodiment of the plaster also provides that it on the side facing the wound in the area between the areas equipped with adhesive 6 share a counteracting adhesive with the wound lamination with a adhesive or adhesive film 7 , which with the Breaks 4 of the staple strip 5 has congruent openings. Both the staple plaster strip 5 and the adhesive film 7 in the wound area can have punched-out openings 4 of different geometry.

Breakthroughs 4 of elongated holes are preferably provided here, which strip 5 extend in the longitudinal direction of the staple band, as shown in FIG. 3. But also a window in any other geometric shape is possible, for example in the form of a macro perforation, for example in the manner of a honeycomb pattern. However, it should be noted that in spite of the punched-out sections of the Klammerpflasterstrei fen 5 must have a sufficiently large power transmission capacity and the possibility of a problem-free visual inspection and drainage of wound fluid. Furthermore, the plaster strip 5 must be equipped outside of the wound area with an adhesive 6 which is on the one hand skin-friendly and on the other hand has a relatively high shear strength. Various synthetic rubber and polyacrylate adhesives are available for this purpose and are known to the person skilled in the art. Clinging plaster strips 5 and wound pads 1 , 2 , 3 can be assembled as a wound care product as a ready-to-use clamp plaster in the configuration shown in FIG. 1. Preferably, the plaster strip 5 and the wound pad 1 , 2 , 3 are applied in succession, a copy on separate cover papers or cover sheets 8 being necessary. As a result of the separate design of the wound pad 1 , 2 , 3 , in the present case, according to the position in FIG. 1, the unused back of the cover paper or the cover sheet 8 of the plaster strip 5 can be used as cover sheet for the wound pad 1 , 2 , 3 . For use, the plaster strip 5 is then pulled off the cover sheet 8 and applied to the skin of a patient while joining the wound edges, and only then is the wound pad 1 , 2 , 3 removed from the protective sheet 8 still adhering to it and in accordance with the illustration in Fig. 3 glued to the staple strips. The latter arrangement corresponds to the sectional view in FIG. 2, but then the protective film 8 is removed and the staple plaster is fixed on the wound.

As already stated, the actual staple plaster strip 5 for transmitting the stapling forces of the wound closure is made of non-stretchable material. Known fabrics and foils are suitable for this, although a material-reinforcing lamination will be necessary in some cases.

The staple plaster strip 5 is expediently produced from an endless strip in a rectangular shape. For particularly difficult applications, however, other plasters such as oval or circular plasters are also advantageously possible.

The staple bandage according to the invention is straightforward, useful for injuries with gaping wound edges suitable and enables for seamless wound closure sucking up in the first phase of blood clotting of blood and exudate secretions and additionally results optimal wound healing conditions such as germ barrier, thermal Isolation and padding from accidental contact. In this respect, the invention ideally fulfills the above named task.
