Abstract

A conformable wound dressing system is provided. The system includes a wound dressing and a dressing support layer. The wound dressing comprises a backing with two major surfaces, first and second lateral edges, an adhesive disposed on one major surface and the dressing support layer removably mounted on the other major surface. The dressing support layer comprises juxtaposed first and second sections that define a gap between them. Each section comprises a medial portion and at least four spokes extending therefrom toward a lateral edge. The at least four spokes comprise two outer spokes and at least two spaced-apart inner spokes. At least two of the at least four spokes of each section extend beyond the lateral edge to form peripheral support layer tabs.

Claims

1. A wound dressing system, comprising:

a wound dressing having a first end a second end opposite the first end, and a longitudinal axis extending from the first end to the second end;

the wound dressing comprising;

an elastic film backing, the backing comprising a first major surface, a second major surface opposite the first major surface, and a perimeter that includes first and second lateral edges, the lateral edges extending from the first end to the second end;

an adhesive disposed on the first major surface; and

a dressing support layer comprising juxtaposed first and second sections removably mounted on the second major surface of the backing, wherein the juxtaposed first and second sections define a gap between the sections, wherein the gap extends substantially from the first end to the second end;

wherein each section comprises a medial portion extending from about the first end to about the second end, and at least four spokes extending therefrom toward a lateral edge, wherein the at least four spokes comprise a first outer spoke extending substantially to the perimeter at the first end, a second outer spoke extending substantially to perimeter at the second end, and at least two spaced-apart inner spokes disposed therebetween;

wherein at least two of the at least four spokes of each section extend beyond the lateral edge to form peripheral support layer tabs;

wherein the dressing support layer defines a plurality of covered portions and uncovered portions of the backing.

2. The wound dressing of claim 1, wherein the first and second lateral edges extend substantially parallel to the longitudinal axis.

3. The wound dressing system of claim 1, wherein the plurality of uncovered portions including at least two uncovered portions along the first lateral edge and at least two uncovered portions along the second lateral edge.

4. The wound dressing of claim 1, wherein at least one outer spoke of at least one section of the dressing support layer extends along a portion of the first lateral edge or the second lateral edge.

5. The wound dressing system of claim 1, wherein at least one of the inner spokes of the first section extends toward the first lateral edge substantially opposite one of the inner spokes of the second section.

6. The wound dressing system of claim 1, wherein the first outer spoke of at least one of the sections extends along a portion of the perimeter of the backing at the first end and/or at the second end.

7. The wound dressing system of claim 1, wherein the first outer spoke extends along at least 20 percent of the perimeter at the first end and/or the second outer spoke extends along at least 20 percent of the perimeter at the second end.

8. The wound dressing system of claim 1, wherein the outer spoke of the first section, at the first end of the dressing, comprises a peripheral support layer tab;

wherein each of the other spokes of the first section, in order from the first end to the second end, alternate between a spoke not having a peripheral support layer tab and a spoke having a peripheral support layer tab.

9. The wound dressing system of claim 1, wherein each section of the dressing support layer comprises three inner spokes.

10. The wound dressing system of claim 1, wherein at least one of the inner spokes of each section extends substantially along a line that is perpendicular to the longitudinal axis.

11. The wound dressing system of claim 1, wherein a plurality of inner spokes of each section extend along lines that are each substantially perpendicular to the longitudinal axis.

12. The wound dressing system of claim 5, wherein at least one of the inner spokes of the first section and a corresponding inner spoke opposite thereof in the second section each comprises a visible indicium.

13. The wound dressing system of claim 1, wherein the plurality of uncovered portions includes an uncovered portion along the perimeter at first end or at the second end.

14. The wound dressing of claim 1, wherein the plurality of uncovered portions includes an uncovered portion that forms a part of the gap.

15. The wound dressing system of claim 1, wherein the dressing support layer comprises a bridge member overlapping the backing and spaced apart from the medial portion, the bridge member connecting a first spoke to a second spoke adjacent the first spoke;

wherein the first spoke, the second spoke, the medial portion, and the bridge member define an uncovered portion of the backing.

16. The wound dressing system of claim 12:

wherein the dressing support layer comprises a first inner spoke of the first section and a second inner spoke of the second section;

wherein both the first inner spoke and second inner spoke comprise lines of indicia;

wherein the first inner spoke extends away from the longitudinal axis opposite the second inner spoke;

wherein cutting the system along a line defined by the lines of indicia creates two smaller wound dressing systems of approximately equal size.

17. The wound dressing system of claim 1, further comprising a bond-block zone on the second major surface of the backing, wherein the support layer is not bonded to the second major surface of the backing in the bond-block zone.

18. The wound dressing system of claim 1, wherein the gap forms a line of symmetry for dressing support layer.
