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

摘要

A reduced pressure treatment system includes a reduced pressure source and a reduced pressure dressing. The dressing includes an interface layer adapted to be positioned at a tissue site and 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. A diverter layer is positioned adjacent the absorbent layer, and the diverter layer includes a plurality of apertures in fluid communication with the absorbent layer to distribute a reduced pressure to the absorbent layer. A cover is positioned over the diverter layer to maintain the reduced pressure at the tissue site.

1. A system for treating a tissue site, comprising:
a reduced pressure source; a dressing adapted to be in fluid communication with the reduced pressure source to distribute reduced pressure to the tissue site, the reduced pressure source positioned external to the dressing, the 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; anda diverter layer adapted to be positioned in fluid communication between the absorbent layer and the reduced pressure source to direct the liquid radially outward from the center region of the absorbent layer to 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.
