A dressing for moist wounds has a body layer 1 of resiliently compressible, moisture-absorbent polyurethane foam, a wound contacting layer 3 of moisture permeable material and an outer barrier layer 2 of gas permeable material which has at least 2 reduced moisture permeability relative to the body layer. The wound contacting layer may comprise a collapsed or compressed polyurethane foam and the barrier layer may be a high density, closed cell polyurethane foam. At least one layer may be impregnated with an antiseptic and a hydrogel may be applied to the wound contacting surface. The dressing may additionally have an active carbon layer and retaining layer therefor, may have cross-cuts for use as a tracheostomy and cannula dressing and may have an adhesive covered perimeter (Fig. 12). <IMAGE> |
