Abstract

A wound treatment device includes a seal of variable size for attaching the device to various locations on a patient for treatment of wounds or lesions. The seal has a plurality of weakened areas which allow portions of the seal to be removed for increasing the size of the seal opening to accommodate wounds or lesions of different size.

Claims

1. A wound treatment device, comprising:

an enclosure defining an interior region having an opening in communication with the interior region;

a seal affixed to the enclosure surrounding the opening having a plurality of weakened regions of increasing size, whereby a portion of the seal can be separated from another portion of the seal along the weakened regions;

a fluid inlet in communication with the interior region; and

a fluid outlet in communication with the interior region.

2. The device of claim 1, wherein the plurality of weakened regions comprise perforations in the enclosure and the seal.

3. The device of claim 1, wherein the plurality of weakened regions comprise a plurality of tear lines.

4. The device of claim 3, wherein the tear lines include strings to be pulled.

5. The device of claim 1, wherein the seal includes a closed cell foam.

6. The device of claim 1, wherein the enclosure is formed of a first sheet and a second sheet attached to each other at their respective edges.

7. The device of claim 1, wherein an outer edge of the seal is affixed to the enclosure adjacent an inner edge of the enclosure opening.

8. The device of claim 1, wherein the weakened regions include portions of the enclosure.

9. The device of claim 1, wherein the weakened regions form concentric rings of increasing size.

10. A wound treatment device, comprising:

an enclosure having an opening; and

a seal coupled to the enclosure surrounding the opening, the seal having portions surrounding the opening constructed to be separated from adjacent portions of the seal.

11. The device of claim 10, wherein the seal and the enclosure have a plurality of corresponding weakened regions.

12. The device of claim 11, wherein the weakened regions comprise concentric rings of increasing size.

13. The device of claim 11, wherein the weakened regions comprise tear lines.

14. A wound treatment device, comprising:

an enclosure having a first opening; and

a seal having a variable size second opening disposed on the enclosure surrounding the first opening, wherein the seal is adapted to be releasably attached to a patient'"'"'s skin.

15. The device of claim 14, wherein an outer edge of the seal is attached adjacent an inner edge of the first opening.

16. The device of claim 14, wherein the variable size second opening comprises a plurality of concentric regions of the seal separated by a first plurality of weakened regions.

17. The device of claim 16, wherein the enclosure includes a second plurality of weakened regions aligned with, the first plurality of weakened regions.

18. A wound treatment device, comprising:

an enclosure defining an interior region; and

a seal overlying the enclosure, wherein the seal and the enclosure have a plurality of corresponding weakened regions of increasing size, whereby a portion of the seal and the enclosure can be separated from another portion of the seal and the enclosure along the weakened regions to form an opening.

19. The device of claim 18, further comprising a fluid inlet in communication with the interior region and a fluid outlet in communication with the interior region

20. The device of claim 18, wherein a portion of the enclosure can be separated from another portion of the enclosure along the weakened regions when corresponding weakened regions of the seal are removed.

21. The device of claim 18, wherein the weakened regions comprise by tear lines.

22. The device of claim 21, wherein the tear lines are perforations formed in the enclosure and the seal.

23. A method of sizing a wound treatment device comprising:

providing an enclosure having a first opening in communication with an interior of the enclosure;

providing a variable size seal coupled to the enclosure surrounding the opening; and

removing a portion of the seal to form a second opening larger than the first opening in communication with the interior.

24. The method of claim 23, further comprising providing weakened regions of increasing size on the enclosure and the seal

25. The method of claim 24, wherein removing the portion of the seal removes a corresponding portion of the enclosure along the weakened regions.

26. The method of claim 24, wherein forming the weakened regions includes perforating the enclosure in concentric rings of increasing size

27. The method of claim 23, wherein providing the variable size seal includes forming weakened regions of increasing size on the seal.

28. The method of claim 27, wherein forming the weakened regions includes perforating the seal in concentric rings of increasing size.

29. A method of sizing a wound treatment device comprising:

providing an enclosure having an interior;

providing a variable size seal coupled to the enclosure; and

removing a portion of the seal to form a first opening in communication with the interior.

30. The method of claim 29, wherein removing the portion of the seal removes a corresponding portion of the enclosure.

31. The method of claim 30, further comprising forming weakened regions of increasing size on the enclosure.

32. The method of claim 31, wherein forming the weakened regions includes perforating the enclosure in concentric rings of increasing size

33. The method of claim 29, wherein providing the variable size seal includes forming weakened regions of increasing size on the seal.

34. The method of claim 33, wherein forming the weakened regions includes perforating the seal in concentric rings of increasing size.

35. A method of making a wound treatment device comprising:

providing an enclosure having an opening in communication with an interior of the enclosure;

providing a seal coupled to the enclosure adjacent the opening; and

weakening aligned concentric portions of the seal and the enclosure.

36. The method of claim 35, wherein the step of weakening includes perforating the seal and enclosure at concentric portions of the seal and enclosure to form tear lines.

37. The method of claim 35, wherein the step of weakening the enclosure includes attaching a string at the tear lines.
