First Claim
Patent Images
1. A suction head for applying suction to a wound area, said suction head comprising:
- a first face having a substantially planar flange and a connector, said connector being adapted to connect to a suction tube;
a second face having a plurality of projections;
an aperture from said second face, through said flange and to said connector on said first face; and
wherein said projections define a plurality of channels, said channels being adapted to facilitate flow of fluids from about said second face toward said aperture.

Abstract
A surgical drape and suction head combination for attaching the suction head to a wound area. 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.

11. A wound therapy combination, said combination comprising:
-
a suction head having a first face, a second face opposite said first face and an opening between said first face and said second face, said opening being adapted for connection to a suction tube;
a surgical drape having an aperture coincident said opening, said surgical drape extending over a region, and overlapping beyond the perimeter, of said first face; and
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.

12. A method for securing a substantially planar, flanged suction head to a wound site, said method comprising the steps of:
-
providing a surgical drape, said surgical drape comprising;
a flexible adhesive-coated plastic film, said adhesive-coated plastic film having a cross sectional area greater than that of the flanged suction head;
a first releasable protective layer, said first protective layer being of substantially the same cross section as the flanged suction head and being adapted to cover the central portion of the adhesive coating of said adhesive-coated plastic film; and
a second releasable protective layer, said second protective layer having a cross sectional area substantially the difference of said adhesive-coated plastic film and said first protective layer and being adapted to cover the non-central portions of the adhesive coating of said adhesive-coated plastic film;
releasing said first protective layer from said adhesive-coated plastic film;
adhering said surgical drape to the substantially planar, flanged suction head;
releasing said second protective layer from said adhesive-coated plastic film; and
applying the substantially planar, flanged suction head to the wound site. - View Dependent Claims (13, 14, 15)

16. A method for securing a suction device to a wound site, said method comprising the steps of:
-
applying a layer of open-celled polymer foam to the wound site;
applying a suction head to the wound site, said suction head comprising a first face, a second face and an opening between said first face and said second face; and
hermetically sealing said suction head and said foam within a region about the wound site with a surgical drape, said surgical drape comprising a flexible adhesive-coated plastic film and a plastic strengthening layer, said strengthening layer being thicker and less flexible than said adhesive-coated plastic film and being applied to the side of said adhesive-coated plastic film opposite the adhesive coating. - View Dependent Claims (17, 18, 19, 20)
