Abstract

A conformable wound dressing system that includes a backing and a dressing support layer. The backing has a first major surface, a second major surface opposite the first major surface, a perimeter that includes first and second lateral edges extending from a first end to a second end, and a longitudinal axis extending form the first end to the second end. An adhesive is on the first major surface and a dressing support layer is on the second major surface. The dressing support layer has a first section and second section where the first section is disconnected and spaced apart from the second section to define a gap extending from the first end of the backing to the second end of the backing.

First claim

The invention claimed is:

1. A wound dressing system, comprising:
an elastic film backing, the backing comprising a first major surface, a second major surface opposite the first major surface, a perimeter that includes first and second lateral edges extending from a first end to a second end, a longitudinal axis extending from the first end to the second end;
an adhesive on the first major surface of the backing; and
a dressing support layer on the second major surface of the backing comprising juxtaposed first and second sections,
the first section having a medial portion extending from the first end to the second end and four spokes extending perpendicularly from the medial portion towards the first and second lateral edges;
the second section having a medial portion extending from the first end to the second end and four spokes extending perpendicularly from the medial portion towards the first and second lateral edges,
wherein the first section is disconnected and spaced apart from the second section to define a gap between the first and second sections that extends from the first end of the backing to the second end of the basking backing; and
wherein the four spokes of the first section comprise a first outer spoke extending substantially to and along the perimeter at the first end, a second outer spoke extending substantially to and along the perimeter at the second end, and two spaced-apart inner spokes disposed therebetween; and
wherein the four spokes of the second section comprise a first outer spoke extending substantially to and along the perimeter at the first end, a second outer spoke extending substantially to and along the perimeter at the second end, and two spaced-apart inner spokes disposed therebetween.

2. The wound dressing system of claim 1 , wherein at least one of the four spokes of the first section comprises an area of weakness extending along a path.

3. The wound dressing system of claim 2 , wherein the area of weakness is one of a perforation, slit, plurality of perforations, plurality of slits, or fold line.

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

5. The wound dressing system of claim 1 , wherein at least one of the four spokes of the first section comprises a visible indicia extending along a path.

6. The wound dressing system of claim 1 , wherein each of the two spaced-apart inner spokes of the first section and each of the two spaced-apart inner spokes of the second section comprises an area of weakness extending along a path.

7. The wound dressing system of claim 1 , wherein the dressing support layer is removably secured to the second major surface of the backing.
