Patent ID: 7790946

Claim:
A wound dressing apparatus for use in subatmospheric pressure therapy, which comprises: an outer member dimensioned for positioning relative to a wound bed to substantially enclose the wound bed, the outer member defining an internal reservoir; a port associated with the outer member and in communication with the reservoir for applying subatmospheric pressure to the reservoir to facilitate treatment of the wound bed and removal of fluid therefrom; an inner member at least partially positionable within the wound bed and confined within the outer member; a layer of an adhesive agent disposed on the outer member to facilitate attachment thereof relative to the wound bed; and a release member mounted to the layer of the adhesive agent in at least partial superimposed relation with the outer member, the release member defining a plurality of concentric release sections extending from a central release section substantially encompassing a centermost segment of the outer member, each release section being selectively separable to expose a predetermined area of the layer of the adhesive agent.
