Abstract

A wound management system can comprise a surgically acceptable adhesive disposed over a wound and a surgically acceptable film repositionably disposed over the surgically acceptable adhesive, and methods of managing a wound involving the same.

Claims (42)

1. A wound management system, comprising

a surgically acceptable cyanoacrylate skin adhesive disposed over and in direct contact with a wound; and

a surgically acceptable film disposed over the surgically acceptable skin adhesive, wherein the surgically acceptable film is in contact with and repositionably binds to a cured surgically acceptable skin adhesive when the surgically acceptable skin adhesive is in direct contact with the wound, and wherein both the surgically acceptable cyanoacrylate skin adhesive and the surgically acceptable film cover the wound.

2. The wound management system of claim 1 , wherein the surgically acceptable skin adhesive comprises at least one of butylcyanoacrylate and octylcyanoacrylate.

3. The wound management system of claim 2 , wherein the surgically acceptable adhesive comprises octylcyanoacrylate.

4. The wound management system of claim 1 , wherein the surgically acceptable film comprises a first side and a second side, the first side having a pressure sensitive adhesive disposed thereon.

5. The wound management system of claim 1 , wherein the surgically acceptable film comprises a silicone sheet.

6. The wound management system of claim 1 , wherein the surgically acceptable film comprises a silicone adhesive.

7. The wound management system of claim 1 , wherein the surgically acceptable film is formed by disposing a curable gel or curable liquid over the surgically acceptable skin adhesive and curing the curable gel or curable liquid into a film.

8. The wound management system of claim 1 , wherein the surgically acceptable film is permeable to at least one of air, moisture, blood, and wound exudate.

9. The wound management system of claim 1 , wherein the surgically acceptable film is semi-permeable to at least one of air, moisture, blood, and wound exudate.

10. The wound management system of claim 1 , wherein the surgically acceptable film is impermeable to at least one of air, moisture, blood, and wound exudate.

11. The wound management system of claim 1 , wherein the surgically acceptable film is transparent or translucent.

12. The wound management system of claim 1 , wherein the surgically acceptable film is opaque.

13. The wound management system of claim 1 , wherein the surgically acceptable film is adapted to change from transparent or translucent to opaque.

14. The wound management system of claim 1 , wherein the surgically acceptable film is in the form of a surgically acceptable tape, dressing or bandage.

15. The wound management system of claim 1 , wherein the surgically acceptable adhesive is an atraumatic adhesive.

16. The wound management system of claim 1 , wherein the surgically acceptable film comprises one or more of silicone, paper, cellulose, microporous material, polyamide, polyacrylate, polyester, copolyester, and fabric.

17. The wound management system of claim 16 , wherein the surgically acceptable film comprises silicone.

18. The wound management system of claim 17 , wherein the surgically acceptable film has a first surface comprising silicone and a second surface comprising one or more of paper, cellulose, microporous material, polyamide, polyacrylate, polyester, copolyester, and fabric.

19. The wound management system of claim 1 , wherein the surgically acceptable film is perforated.

20. The wound management system of claim 1 , wherein the surgically acceptable film is not perforated.

21. The wound management system of claim 1 , further comprising an absorbent dressing disposed over the surgically acceptable film.

22. The wound management system of claim 1 , further comprising at least one topically administrable active agent.

23. The wound management system of claim 22 , wherein the topically administrable active agent comprises one or more of antimicrobials, moisturizers, vitamins, skin nutrients, beneficial oils, and scar reducing agents.

24. The wound management system of claim 1 , wherein the surgically acceptable film comprises one or more markings delineating one or more pre-determined shapes on the film.

25. A method of managing a wound, comprising

applying a surgically acceptable cyanoacrylate skin adhesive directly to a wound; and

then applying a repositionable surgically acceptable film over the surgically acceptable skin adhesive wherein the surgically acceptable film is contacted with and bonds to the surgically acceptable skin adhesive, and wherein both the surgically acceptable cyanoacrylate skin adhesive and the surgically acceptable film cover the wound.

26. The method of claim 25 , further comprising curing the surgically acceptable skin adhesive, wherein the cured skin adhesive does not impede the repositionability of the surgically acceptable film.

27. The method of claim 25 , wherein the surgically acceptable skin adhesive comprises one or more of butylcyanoacrylate and octylcyanoacrylate.

28. The method of claim 25 , wherein the surgically acceptable skin adhesive comprises octylcyanoacrylate.

29. The method of claim 25 , wherein the repositionable surgically acceptable film is applied before the surgically acceptable skin adhesive is completely cured.

30. The method of claim 25 , wherein the repositionable surgically acceptable film is applied after the surgically acceptable skin adhesive is completely cured.

31. The method of claim 25 , wherein the repositionable surgically acceptable film is a surgically acceptable tape, dressing, or bandage.

32. The method of claim 25 , wherein the surgically acceptable film is applied as a transparent or translucent film, and becomes opaque over time.

33. The method of claim 25 , further comprising applying an absorbent dressing over the repositionable surgically acceptable film.

34. The method of claim 25 , further comprising applying a topically acceptable active agent to the wound.

35. The method of claim 34 , wherein the topically acceptable active agent includes one or more of anti-microbials, moisturizers, vitamins, skin nutrients, beneficial oils, and scar reducing agents.

36. The method of claim 25 , wherein the surgically acceptable skin adhesive is applied from a sponge-tipped applicator, a high-density foam applicator, a flocked-tipped applicator, or a silicone-tipped applicator.

37. The method of claim 36 , wherein the applicator is a blister-sealed applicator.

38. The method of claim 25 , further comprising repositioning the repositionable surgically acceptable film after applying the repositionable surgically acceptable film.
