Abstract

Claims (32)

1 . A device comprising:

a reactive gas generator designed for generating reactive gases; and

a patch designed for local treatment of wounds, delimited toward an outside, wherein the patch includes at least one inlet port configured for introducing the reactive gases,

wherein a covering device of the patch is selected from the group consisting of an occlusive film, a distribution film, and combinations thereof,

wherein an open cell foam blended with activated charcoal encircles a fastening edge of the patch and a treatment area to thereby reduce a concentration of the reactive gases outside of the treatment area, and

wherein the treatment area is enclosed by the fastening edge, wherein the open cell foam does not cover the treatment area.

2 . The device of claim 1 , wherein the patch comprises at least one outlet port configured for removing the reactive gases from the treatment area.

3 . The device of claim 2 , wherein the open cell foam blended with activated charcoal is arranged in the treatment area, which covers the outlet port.

4 . The device of claim 1 , wherein the fastening edge of the covering device is fastenable to skin.

5 . The device of claim 4 , wherein the fastening edge comprises an adhesive layer embodied as an adhesive film, and wherein the adhesive layer forms an outer boundary surface of the covering device that faces away from the treatment area.

6 . A treatment kit for fabricating the device of claim 1 , the treatment kit comprising:

the patch and the open cell foam blended with activated charcoal.

7 . The device of claim 1 , wherein the covering device is a covering film, and wherein the covering film is the occlusive film.

8 . The device of claim 7 , wherein the at least one inlet port is connected to an adapter, which is mounted gas-tight onto the occlusive film.

9 . The device of claim 7 , wherein the covering device further comprises a foam, a superabsorber, a fleece, or combinations thereof.

10 . The device of claim 2 , wherein the reactive gases are introducible in the treatment area via the inlet port using a tubular film.

11 . The device of claim 5 , wherein the adhesive layer comprises a gas-permeable material.

12 . The device of claim 1 , wherein the concentration of the reactive gases is regulated by a cell density, a cell size and an effective surface of the open cell foam blended with activated charcoal.

13 . A device comprising:

a reactive gas generator designed for generating reactive gases; and

a patch designed for local treatment of wounds, delimited toward an outside, wherein the patch includes at least one inlet port configured for introducing the reactive gases,

wherein a covering device of the patch is selected from the group consisting of an occlusive film, a distribution film, and combinations thereof,

wherein an open cell foam blended with activated charcoal encircles a fastening edge of the patch and a treatment area, and

wherein the treatment area is enclosed by the fastening edge, wherein the open cell foam does not cover the treatment area.

14 . The device of claim 13 , wherein a concentration of the reactive gases is regulated by a cell density, a cell size and an effective surface of the open cell foam blended with activated charcoal.

15 . A device comprising:

a reactive gas generator designed for generating reactive gases; and

a patch designed for local treatment of wounds, delimited toward an outside, wherein the patch includes at least one inlet port configured for introducing the reactive gases,

wherein a covering device of the patch is selected from the group consisting of an occlusive film, a distribution film, and combinations thereof,

wherein an open cell foam blended with activated charcoal encircles a fastening edge of the patch and a treatment area,

wherein the open cell foam is frame-shaped, and

wherein an inner area of the frame is free of the open cell foam.
