Abstract:
1. An apparatus for applying negative pressure to a superficial wound in a mammal, said apparatus comprising: a flexible porous pad, said porous pad comprising an open, intercommunicating cellular foam; a connector for introduction of the negative pressure to said porous pad, said connector comprising a disc-like member having a lower face in contact with said porous pad and a spout opposite said lower face for connection to an end of a suction tube; a surgical drape for forming a substantially air-tight seal over said porous pad, said connector and the wound site; and a multi-lumen suction tube, having a center lumen and a plurality of outer lumens, for connecting said porous pad through said connector, to a negative pressure source; wherein said multi-lumen tube is adapted to allow fluid to be drawn from the wound via the center lumen while simultaneously allowing pressure at the wound site to be monitored via at least one of the plurality of outer lumens.
