Patent ID: 8372049

Claim:
A reduced pressure treatment system comprising: a reduced pressure source; and a dressing comprising: an interface layer adapted to be positioned at a 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 diverter layer formed from a substantially liquid-impermeable material and positioned between the absorbent layer and the reduced pressure source, the diverter layer including a plurality of apertures in fluid communication with the absorbent layer to distribute a reduced pressure 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 diverter layer to maintain the reduced pressure at the tissue site; and wherein a surface area of the diverter layer is greater than a surface area of the cover; and wherein the reduced pressure source is located external to the dressing and fluidly coupled to the dressing.
