Patent ID: 7988680

Claim:
A method for treating an open wound having a wound surface, the method comprising: providing a generally non-porous flexible member having a plurality of holes opening through a wound contactable surface, a port defining a single passageway adapted to selectively communicate with a vacuum source and a source of liquid, a plurality of passageways providing direct communication through the flexible member between each of the plurality of holes and the single passageway of the port, and a stand-off having interconnected portions coupled to the wound facing surface and configured to provide a space between the wound facing surface and a wound surface, placing the member into contact with the wound, connecting the single passageway of the port to the source of liquid and dispersing the liquid to the wound through the single passageway of the port, the plurality of passageways of the member, and each of the holes to irrigate the wound, connecting the single passageway of the port to the vacuum source to provide suction at each of the plurality of holes to draw the liquid away from the wound through each of the holes, and operating a switch valve to selectively communicate either liquid or suction through the single passageway of the flexible member to the wound.
