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.

Claims

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.
