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 sacral region of a patient, comprising:

a base layer comprising a first surface, a second surface, an interior region and an outer perimeter; and

a sacral sealing region comprising a non-planar configuration having a generally tapered shape from the outer perimeter toward the interior region of the base layer and from the second surface of the base layer to a peak region projecting from the second surface; and

an adhesive layer located on the sacral sealing region and the second surface of the base layer and substantially along the outer perimeter of the base layer.

2. The device of claim 1, wherein the sacral sealing region further comprises a cavity.

3. The device of claim 2, wherein the sacral sealing region further comprises a foam located in the cavity.

4. The device of claim 2, wherein the sacral sealing region further comprises an access valve in communication with the cavity, the access valve being located on the first surface of the sacral sealing region.

5. The device of claim 1, wherein the sacral sealing region is integrally formed with the base layer.

6. The device of claim 1, wherein the sacral sealing region further comprises a sacral sealing structure that is attached to the base layer.

7. The device of claim 6, wherein the sacral sealing structure is attached at the point of manufacture.

8. The device of claim 6, wherein the sacral sealing structure is attached at the point of use.

9. The device of claim 1, wherein the sacral sealing region comprises a distalmost surface that has a non-parallel orientation with respect to the base layer.

10-25. -25. (canceled)

26. A device to treat a sacral region of a patient, comprising:

a dressing comprising a first layer, a second layer disposed over the first layer, an interior region, and an outer perimeter;

a sacral sealing region comprising a non-planar configuration having a generally tapered shape from the outer perimeter toward the interior region of the dressing and from a surface of the dressing to a peak region projecting from the surface of the dressing; and

an adhesive layer located on the sacral sealing region and the first layer of the dressing and substantially along the outer perimeter of the dressing, wherein when the adhesive layer is configured to couple the dressing and the sacral sealing region to a wound location, the second layer is configured to be removed from the first layer without decoupling the dressing and the sacral sealing region from the wound location.

27. The device of claim 26, wherein when the second layer is removed from the first layer, an opening is exposed that is configured to provide direct access to a wound at the wound location.

28. The device of claim 26, wherein the sacral sealing region further comprises a cavity, and wherein the sacral sealing region further comprises a foam located in the cavity.

29. The device of claim 28, wherein the sacral sealing region further comprises an access valve in communication with the cavity, the access valve being located on a surface of the sacral sealing region.

30. The device of claim 26, wherein the sacral sealing region is integrally formed with the dressing.

31. The device of claim 26, wherein the sacral sealing region further comprises a sacral sealing structure that is attached to the dressing.

32. The device of claim 26, wherein the sacral sealing region comprises a distalmost surface that has a non-parallel orientation with respect to a base layer.

33. The device of claim 26, wherein the second layer is coupled to a reduced pressure source and is configured to provide fluid communication between a wound at the wound location and the reduced pressure source.

34. The device of claim 26, wherein the dressing is coupled to a reduced pressure source and is configured to provide fluid communication between the wound location and the reduced pressure source to provide reduced pressure at the wound location, and wherein the second layer is configured to be removed from the first layer while reduced pressure is maintained at the wound location.
