Abstract

Reduced pressure wound therapy is performed on a sacral region of a patient using an adhesive dressing comprising a flexible planar layer and a non-planar fold-sealing region configured to seal to the intergluteal cleft of a patient. The fold-sealing region is located on an outer edge of the adhesive dressing and comprises a tapered configuration.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1. A device to treat a region of a patient having a skin fold, comprising:
a multi-lobular base layer comprising a first surface, a second surface, an interior region, and an outer perimeter, wherein each lobular region of the base layer comprises a curve that converges at a central axis of the base layer;
wherein the base layer further comprises a branched conduit system; and
an adhesive conduit located on the base layer, wherein the adhesive conduit encloses an area of the base layer.

2. The device of claim 1 , further comprising an adhesive port in fluid connection with the adhesive conduit.

3. The device of claim 1 , further comprising an oblong tubing attached to the base layer, wherein the oblong tubing is embedded in a soft material support or in a gel-filled support.

4. The device of claim 1 , wherein the multi-lobular base layer has at least four lobular regions.

5. The device of claim 1 , wherein the multi-lobular base layer has at least two lobular regions.

6. The device of claim 1 , wherein the multi-lobular base layer is asymmetric across any axis.

7. The device of claim 1 , wherein the multi-lobular base layer is symmetric across at least one axis.

8. The device of claim 1 , further comprising a fold-sealing region located about the central axis of the base layer.

9. The device of claim 3 , wherein the oblong tubing is orthogonal to the central axis of the base layer.

10. The device of claim 3 , wherein the oblong tubing is configured to resist occlusion.

11. The device of claim 3 , wherein the oblong tubing is directly attached only to the first or second surface of the base layer.

12. The device of claim 3 , wherein the oblong tubing is embedded between the first and second surface of the base layer.

13. The device of claim 3 , wherein the oblong tubing is directly attached to both the first and second surface of the base layer.

14. A method of treating a wound having a skin fold, comprising:
providing a device comprising a multi-lobular base layer comprising a first surface, a second surface, an interior region, and an outer perimeter, wherein each lobular region of the base layer comprises a curve that converges at a central axis of the base layer; and an adhesive conduit located on the base layer, wherein the adhesive conduit encloses an area of the base layer;
placing the device along the skin fold of the wound such that the central axis of the device is aligned with the skin fold; and
adhering the device to the wound such that a substantially airtight seal is formed between the wound and the device.

15. The method of claim 14 , further comprising an adhesive port in fluid connection with the adhesive conduit.

16. The method of claim 14 , further comprising:
providing oblong tubing; and
placing the oblong tubing in an orthogonal direction to the central axis of the base layer.

17. The method of claim 14 , wherein the multi-lobe base layer has at least two lobular regions, further comprising placing a first of the at least two lobular regions on a first side of the skin fold, and a second of the at least two lobular regions on a second side of the skin fold.

18. The method of claim 14 , wherein the device further comprises a fold-sealing region located about the central axis of the base layer, further comprising aligning the fold-sealing region with the skin fold.

19. The method of claim 14 , further comprising providing oblong tubing, wherein the oblong tubing is directly attached only to the first or second surface of the base layer.

20. The method of claim 14 , further comprising providing oblong tubing, wherein the oblong tubing is directly attached to both to the first and second surface of the base layer.
