Abstract

Apparatuses, methods, and systems disclosed within relate to a wound dressing, suitable for use in negative pressure wound therapy, which may include a body of porous material, the body of porous material including a plurality of cuts which provide regions of flexibility within the body. Methods of manufacturing and methods of use of such wound dressings may also be disclosed herein. In addition, the wound dressing can include a retaining mechanism removably coupled to the material and configured to retain the material in the expanded conformation.

First claim

What is claimed is:

1. A wound dressing, comprising:
an absorbent layer, comprising:
a first dimension and a second dimension, the second dimension perpendicular to the first dimension,
a plurality of first apertures, each first aperture comprising a first slit extending parallel to the first dimension, and a plurality of second slits extending parallel to the second dimension, the second slits intersecting with the first slit, and
a second aperture, the second aperture comprising a third slit extending parallel to the second dimension, and a plurality of fourth slits extending parallel to the first dimension, the third slit intersecting with the fourth slits.

2. The wound dressing of claim 1 , wherein the absorbent layer comprises fibers.

3. The wound dressing of claim 1 , wherein the absorbent layer comprises a plurality of second apertures.

4. The wound dressing of claim 1 , wherein the absorbent layer comprises a plurality of first apertures and a plurality of second apertures.

5. The wound dressing of claim 4 wherein the first apertures and the second apertures are arranged in a row with alternating first apertures and second apertures.

6. The wound dressing of claim 1 , wherein the absorbent layer further comprises a third aperture comprising a fifth slit.

7. The wound dressing of claim 6 , wherein the absorbent layer comprises a plurality of third apertures.

8. A wound pad comprising fibers, the wound pad provided with a plurality of first discrete groups of incisions and a plurality of second discrete groups of incisions, each first group of incisions completely separated from each second group of incisions and extending from an upper surface to a bottom surface of the wound pad, wherein each one of the first and the second discrete groups of incisions comprise a first incision intersecting with a second incision, the first incision extending at an angle from the second incision to a first end point, the second incision extending to a second end point, the first end point spaced from the second end point, wherein a portion of each first discrete group of incisions extends in a first direction across a plane extending in a perpendicular direction from the surface of the wound pad and in a machine direction of the wound pad, and a portion of each second discrete group of incisions extends in a second direction across the plane.

9. The wound pad of claim 8 , wherein the first discrete group of incisions comprises a first common starting point and the second discrete group of incisions comprises a second common starting point.

10. The wound pad of claim 9 , wherein the first common starting point is provided on a first side of the plane and wherein the second common starting point is provided on a second side of the plane.

11. The wound pad of claim 8 , wherein a first group of incisions has the same shape as a second group of incisions.

12. The wound pad of claim 8 , wherein a first group of incisions has the same orientation as a second group of incisions.

13. The wound pad of claim 8 , wherein the wound pad comprises a plurality of a second group of incisions.

14. The wound pad of claim 13 , wherein a first and a second group of incisions are arranged in a row.

15. The wound pad of claim 14 , wherein a first group of incisions alternate with a second group of incisions.

16. The wound pad of claim 13 , wherein each second group of incisions is completely separated from one another.

17. The wound pad of claim 13 , wherein each second group of incisions further comprises a third incision.

18. The wound pad of claim 8 , further comprising an adhesive.

19. The wound pad of claim 8 , wherein each first group of incisions is completely separated from one another.

20. The wound pad of claim 8 , wherein each first group of incisions further comprises a third incision.
