Abstract

This invention relates to a facial mask comprising an covering layer having a first and second surface being cut into a mask shape and having a fluid absorbent adhesive on its first surface. In one embodiment, the covering layer is an occlusive layer. The mask may further include an adjunct moisture absorbing layer between the adhesive layer and the first surface of the covering layer. In another embodiment, the mask further comprises a compressibility layer between the adhesive layer and the first surface of the covering layer. The mask may also include a moldable fluid absorbing layer on the surface of the fluid absorbing adhesive opposite the covering layer. The masks of the present invention promote healing of skin wounds, especially the skin wounds form cosmetic procedures such as laser reconstruction.

Claims

1. A facial mask for wound management comprising a conformable covering layer having a first and second surface and being cut into a mask shape;

and a fluid absorbent adhesive layer having a first surface and a second surface wherein the first surface of the covering layer overlies the second surface of the adhesive layer.

2. The mask of claim 1 wherein the covering layer comprises an occlusive layer.

3. The mask of claim 2 wherein the covering layer has a moisture vapor transmission rate in the range of about 100 to about 2000 g/m²/24 hours.

4. The mask of claim 2 wherein the covering layer has a moisture vapor transmission rate of at least 4000 g/m²/24 hours.

5. The mask of claim 1 wherein the covering layer comprises fabric.

6. The mask of claim 1 wherein the covering layer comprises a polymeric film.

7. The mask of claim 6 wherein the polymeric film is transparent.

8. The mask of claim 1 wherein the covering layer comprises plastic foam.

9. The mask of claim 1 wherein the fluid absorbing adhesive layer comprises at least one adhesive and at least one water soluble and/or water swellable polymer.

10. The mask of claim 9 wherein the adhesive comprises an acrylic based pressure sensitive adhesive, a rubber-based pressure sensitive adhesive, a silicone pressure sensitive adhesive or a combination of two or more thereof.

11. The mask of claim 9 wherein the adhesive comprises at least one medical grade adhesive.

12. The mask of claim 9 wherein the fluid absorbent adhesive comprises sodium carboxymethyl cellulose, dextran, starch-acrylonitirle graft copolymer or a combination of two or more thereof.

13. The mask of claim 9 wherein the fluid absorbent adhesive comprises alginic acid, sodium alginate, calcium alginate, cellulose-derived material, starch or a modified starch, a copolymer of a starch or a cellulosic material, a water soluble hydrocolloid, synthetic resin, mannan, seaweed, plant mucilage or a combination of two or more thereof.

14. The mask of claim 9 wherein the fluid absorbent adhesive comprises pectin, gelatin, starches, guar gum, locust bean gum, gum arabic, collagen, karaya gum, alginic acid and its sodium and calcium salts, sodium carboxymethyl cellulose, polyvinyl alcohol, polyvinyl pyrrolidone, high molecular weight polyethylene glycols and polypropylene glycols or a combination of two or more thereof.

15. The mask of claim 1 wherein the adhesive layer further comprises at least one moisturizing agent.

16. The mask of claim 1 wherein the adhesive layer comprises a thermoplastic polymer and a compatible liquid rubber.

17. The mask of claim 16 wherein the adhesive further comprises one or more low molecular weight polyolefins.

18. The mask of claim 16 wherein the liquid rubber comprises a liquid isoprene polymer, a liquid isoprene-styrene copolymer, a liquid isoprene-butadiene copolymer or combinations of two or more thereof.

19. The mask of claim 1 further comprising an adjunct moisture absorbing layer between the adhesive layer and the first surface of the covering layer.

20. The mask of claim 19 wherein the moisture absorbing layer comprises a hydrocolloid.

21. The mask of claim 19 wherein the moisture absorbing layer comprises a moisture absorbing material capable of absorbing at least 250% by weight saline solution based on the weight of the absorbent material.

22. The mask of claim 19 wherein the moisture absorbing layer comprises a foam.

23. The mask of claim 1 further comprising a compressibility layer between the second surface of the adhesive layer and the first surface of the covering layer.

24. The mask of claim 23 further comprising a fluid absorbing moldable layer on the first surface of the fluid absorbing adhesive layer.

25. The mask of claim 1 further comprising a moldable fluid absorbing layer on the second surface of the fluid absorbing adhesive layer.

26. The mask of claim 1 wherein the adhesive layer comprises at least one thermoplastic elastomer;

at least one liquid rubber;

at least one polyisobutylene; and

at least one oil.
