Abstract

An absorbent dressing for absorbing exudate from a wound is disclosed. The absorbent dressing contains a plurality of dried absorbent hydrogel particles sealed within a porous container. The porous container is non-adherent to the wound, and the hydrogel particles remained sealed within the container after absorbing the wound exudate. In a preferred embodiment, the particles are dried polyacrylonitrile hydrogel particles, and the porous container is in the form of a sachet bag made from nylon, cotton, polyester, polypropylene and the like.
