Absorbent dressing and method

摘要

A system that may be adapted to distribute reduced pressure to a tissue site may include a dressing and a sealing member. The dressing may include a manifold layer, a storage layer, and a plurality of retainers. The manifold layer may be adapted to be positioned proximate the tissue site, and the storage layer may be positioned proximate the manifold layer. The plurality of retainers may be disposed in the storage layer. Each of the retainers may define a fluid communication channel through the storage layer. The retainers may be adapted to substantially preclude deformation of the storage layer into the fluid communication channels. The sealing member may be adapted to cover the dressing and to provide a fluid seal between the sealing member and the tissue site.

1. A system for treating a tissue site, comprising:
a dressing adapted to distribute reduced pressure from a reduced-pressure source to the tissue site, comprising:
a manifold layer adapted to be positioned proximate the tissue site,a first storage layer positioned proximate the manifold layer,a plurality of first fluid communication channels disposed through the first storage layer,a first retainer disposed in each of the first fluid communication channels, wherein the first retainers are adapted to substantially preclude deformation of the first storage layer into the first fluid communication channels,a second storage layer positioned in fluid communication with the first storage layer,a plurality of second fluid communication channels disposed through the second storage layer,a second retainer disposed in each of the second fluid communication channels, wherein the second retainers are adapted to substantially preclude deformation of the second storage layer into the second fluid communication channels,wherein the second fluid communication channels are laterally offset from the first fluid communication channels; anda sealing member adapted to cover the dressing and to provide a fluid seal between the sealing material and the tissue site.
