Abstract
A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.
Claims17
A wound therapy device, comprising:
- a moisture vapor permeable cover layer configured to cover a wound area and an area of body surface adjacent the wound area at least partially enclosing the wound area;
- a protective layer positioned beneath the cover layer and overlying a transmission layer, the protective layer configured to provide stiffness to the wound therapy device and protect the cover layer from the transmission layer, wherein the protective layer is larger than the transmission layer, the transmission layer configured to overlie the wound area and the area of body surface adjacent the wound area at least partially enclosing the wound area, the transmission layer comprising fibers;
- and
- a wound contact layer comprising a silicone adhesive and positioned beneath the transmission layer and the protective layer, the wound contact layer configured to overlie the wound area and the area of body surface adjacent the wound area at least partially enclosing the wound area,
- wherein a portion of an upper outer layer of the transmission layer comprises a first filament count and a portion of a lower outer layer of the transmission layer comprises a second filament count, wherein the first filament count is greater than the second filament count,
- wherein the upper outer layer configured to wick more fluid than the lower outer layer, and
- wherein the upper outer layer of the transmission layer is separated from the lower outer layer by a plurality of fiber spacer elements extending perpendicularly between the upper outer layer and the lower outer layer.
