A B S T R A C T Wound Dressing An absorbent, non-adherent wound dressing-suitable for use in deep and cavernous wounds is described. The dressing comprises an absorbent material in the form of individual pieces of a conformable, resilient, absorbent hydrophilic foam retained within a porous bag formed from a perforated polymeric film. In a preferred form the foam is a hydrophilic polyurethane foam and the perforated polymeric film is a contoured net of a thermoplastic elastomeric polymer. A non-woven fabric may be additionally present between the perforated polymeric film and the pieces of foam. The dressings can absorb large volumes of wound exudate without adhering to the wound.
