Abstract

A wound therapy device comprising a head and a surgical drape. The head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to and from the aperture. The device may provide medicated fluid to the wound evenly while withdrawing wound exudates.

Claims (24)

1. A wound therapy device for applying fluids to and removing fluids from a wound area, comprising:

a fluid source;

a head comprised of a plurality of channels for facilitating flow of fluids to and from an opening of the head, wherein the opening is adapted for connection to a tube;

wherein the tube is adapted to deliver fluids from the fluid source to the wound, and adapted to remove fluids from the wound; and

wherein the channels are defined by a plurality of projections from the head, such that the projections are adapted to be in contact with the wound surface.

2. The wound therapy device of claim 1 , further comprising a surgical drape having an aperture coincident said opening, said surgical drape extending over a region, and overlapping beyond the perimeter of the head, and wherein the surgical drape comprises a flexible adhesive coated film adhered to the region of the head and a release-coated backing extending over the head and adhered to the overlapping portion of the surgical drape.

3. The wound therapy device of claim 2 , further comprising a source of suction connected to the tube adapted to remove fluids from the wound.

4. The wound therapy device of claim 3 , wherein said source of suction is a pump.

5. The wound therapy device of claim 4 , wherein the pump is adapted to deliver fluids from the fluid source to the wound.

6. The wound therapy device of claim 5 , wherein the fluid source contains medicated fluids.

7. A wound therapy device, comprising:

a fluid source;

a head having a first face;

a second face opposite the first face;

an opening through the first face and through the second face; and

a plurality of flow channels in fluid communication with the fluid source for facilitating flow of fluids to the opening.

8. The wound therapy device of claim 7 further comprising a surgical drape having an aperture coincident the opening, the surgical drape extending over a region of the first face, and overlapping beyond the perimeter of the first face.

9. The wound therapy device of claim 8 wherein the surgical drape comprises a flexible adhesive coated film adhered to the region of the first face and a release-coated backing extending over the second face and adhered to the overlapping portion of the surgical drape.

10. The wound therapy device of claim 9 further comprising a foam interposed between the second face and a wound.

11. The wound therapy device of claim 7 further comprising a source of suction in communication with said opening.

12. The wound therapy device of claim 11 wherein said source of suction is a pump.

13. The wound therapy device of claim 12 , wherein the pump is adapted to deliver fluids from the fluid source to the wound.

14. The wound therapy device of claim 13 , wherein the fluid source contains medicated fluids.

15. The wound therapy device of claim 7 wherein said flow channels are defined by a plurality of projections from said second face.
