Dressing and method for applying reduced pressure to and collecting and storing fluid from a tissue site

摘要

A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.

1. A system for treating a tissue site, comprising:
a dressing, comprising:
an absorbent layer adapted to be positioned at the tissue site to absorb liquid from the tissue site, the absorbent layer having a perimeter region and a center region;a pump adapted to be in fluid communication with the absorbent layer to provide reduced pressure to the absorbent layer; anda diverter layer adapted to be positioned in fluid communication between the absorbent layer and the pump to draw the liquid away from the center region of the absorbent layer towards the perimeter region of the absorbent layer; and a cover adapted to be positioned over the dressing to provide a fluid seal relative to the tissue site.
