Patent ID: 8372050

Claim:
A reduced pressure dressing for applying reduced pressure treatment to a tissue site, the reduced pressure dressing comprising: an interface layer adapted to be positioned at the tissue site; an absorbent layer in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site, the absorbent layer having a perimeter region and a center region; a pump in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site; a diverter layer between the absorbent layer and the pump, the diverter layer including a plurality of apertures to transmit the reduced pressure from the pump to the absorbent layer, the apertures positioned on the diverter layer substantially within the perimeter region of the absorbent layer and away from the center region of the absorbent layer; a cover positioned over the pump, the diverter layer, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site; and a liquid-air separator positioned between the diverter layer and the pump to inhibit liquid from entering the pump.
