Abstract
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.
