A sterile wound cover designed to be used in conjunction with a wound therapy oxygenator to actively promote continuous diffusion of oxygen (CDO) in a wound bed to heal various types of wounds (e.g., arterial, venous, diabetic or pressure ulcers, skin grafts, burns, and/or postoperative or traumatic wounds). It is made of synthetic polymer materials and consists of an absorbent open-cell foam layer, an oxygen (O2) distribution foam layer, an occlusive layer to create an O2 rich environment, and integrated O2 tubing/connector. It may have an adhesive border and may be cut to conform to the wound. O2 delivery extension tubing may be included. This is a single-use device.
