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 with reduced pressure therapy, comprising:

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

a fold-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 fold-sealing region and the second surface of the base layer and substantially along the outer perimeter of the base layer;

wherein the second surface of the base layer is configured to be removed from the first surface of the base layer to expose an opening configured to provide direct access to a wound; and

wherein the fold-sealing region comprises a distal most surface at the peak region that has a non-parallel orientation with respect to the base layer.

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

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

4. The device of claim 2, wherein the fold-sealing region further comprises a port in communication with the cavity, the port being located on the first surface.

5. The device of claim 1, wherein the fold-sealing region is integral with the base layer.

6. The device of claim 1, wherein the fold-sealing region further comprises a sacral sealing structure configured to be attached to the base layer.

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

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

9. A device to treat a sacral region of a patient with reduced pressure therapy, comprising:

a dressing comprising a first layer, a second layer disposed over the first layer, an interior region, and an outer perimeter, wherein the dressing is configured to be coupled to a reduced pressure source to provide fluid communication between a wound location and the reduced pressure source to provide reduced pressure at the wound location;

a fold-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 fold-sealing region and the first layer of the dressing and substantially along the outer perimeter of the dressing;

wherein the adhesive layer is configured to couple the dressing and the fold-sealing region to the wound location, and wherein the second layer of the dressing is configured to be removed from the first layer of the dressing without decoupling the dressing and the fold-sealing region from the wound location and to expose an opening configured to provide direct access to a wound at the wound location; and

wherein the fold-sealing region comprises a distal most surface at the peak region that has a non-parallel orientation with respect to the surface of the dressing.

10. The device of claim 9, wherein the fold-sealing region further comprises a cavity, and wherein the fold-sealing region further comprises a foam located in the cavity.

11. The device of claim 10, wherein the fold-sealing region further comprises a port in communication with the cavity, the port being located on a surface of the fold-sealing region.

12. The device of claim 9, wherein the fold-sealing region is integral with the dressing.

13. The device of claim 9, wherein the fold-sealing region further comprises a sacral sealing structure configured to be attached to the dressing.

14. The device of claim 9, wherein the second layer is coupled to the reduced pressure source and is configured to provide fluid communication between a wound at the wound location and the reduced pressure source.

15. The device of claim 9, wherein the second layer is configured to be removed from the first layer while reduced pressure is maintained at the wound location.
