Abstract

A wound therapy combination comprising a suction head and a surgical drape. The suction 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 the aperture.

Claims

1. A wound therapy device for applying suction to a wound area, comprising:

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

wherein said channels are defined by a plurality of projections from said suction head, such that said projections are adapted to be in contact with a 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 said suction head, and wherein said surgical drape comprises a flexible adhesive coated film adhered to said region of said suction head and a release-coated backing extending over said suction head and adhered to the overlapping portion of said surgical drape.

3. The wound therapy device of claim 2, further comprising a source of suction.

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

5. A wound therapy device, comprising:

a suction head having a first face;

a second face opposite said first face;

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

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

6. The wound therapy device of claim 5 further comprising a surgical drape having an aperture coincident said opening, said surgical drape extending over a region of said first face, and overlapping beyond the perimeter of said first face.

7. The wound therapy device of claim 6 wherein said surgical drape comprises a flexible adhesive coated film adhered to said region of said first face and a release-coated backing extending over said second face and adhered to the overlapping portion of said surgical drape.

8. The wound therapy device of claim 7 further comprising a foam interposed between said second face and a wound.

9. The wound therapy device of claim 5 further comprising a source of suction in communication with said opening.

10. The wound therapy device of claim 9 wherein said source of suction is a pump.

11. The wound therapy device of claim 5 wherein said flow channels are defined by a plurality of projections from said second face.
