Abstract

Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus includes one or more wound dressings configured to be used to treat surgical wounds including post-breast surgery wounds. In some embodiments, a single negative pressure source can be used with one or more wound dressing to treat one or more wounds.

Claims (16)

1. A negative pressure wound therapy apparatus, comprising:

a wound dressing comprising a triangular shape, the wound dressing having three sides and three corners, the wound dressing comprising:

a wound contact layer configured to be positioned in contact with a wound, the wound contact layer comprising a first wound facing side and an opposite second side;

an adhesive layer on the first side of the wound contact layer;

an absorbent layer and/or transmission layer positioned over the wound contact layer; and

a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer and/or transmission layer, wherein the cover layer comprises an aperture;

wherein the absorbent layer and/or transmission layer comprise a triangular shape;

wherein the cover layer, the wound contact layer, and the adhesive layer comprise a triangular shape, wherein the cover layer is larger than the absorbent layer and/or the transmission layer to provide a perimeter that extends beyond an edge of the absorbent layer and/or transmission layer, wherein the cover layer and wound contact layer are sealed at the perimeter enclosing the absorbent layer and/or the transmission layer; and

wherein the adhesive layer, the wound contact layer, the absorbent layer and/or transmission layer, and the cover layer are configured to be applied to the wound as an integrated unit and wherein the adhesive layer is configured to adhere the triangular shaped wound dressing to the skin around the wound; and

a fluidic connector positioned over the aperture in the cover layer.

2. The apparatus of claim 1 , wherein the three sides of the wound dressing have a constant curvature along their length.

3. The apparatus of claim 2 , wherein the fluidic connector is positioned adjacent to the edge of one of the three sides of the wound dressing.

4. The apparatus of claim 1 , wherein the fluidic connector is configured to communicate negative pressure to the wound dressing.

5. The apparatus of claim 1 , further comprising a Y-connector configured to provide fluid communication between the wound dressing and fluidic connector and a second wound dressing and second fluidic connector and a negative pressure source.

6. The apparatus of claim 1 , wherein the dressing is sized and configured to cover one or more post-surgical breast wounds, wherein at least one of the sides of the triangular shaped dressing is configured to be aligned parallel to an incision on a lower portion of the breast and a corner of the triangular shaped wound dressing is configured to be positioned over an incision around an areola of a patient.

7. The apparatus of claim 1 , wherein the wound contact layer, absorbent layer and/or transmission layer, and cover layer are configured to extend over skin surrounding the wound.
