Abstract: A portable topical oxygen therapy system includes a miniature gas cylinder containing compressed oxygen, a miniature regulator or having an inlet and an outlet and a wound dressing having an interior configured to cover or enclose an exterior portion of a patient's body. The inlet of the regulator is connected to the gas cylinder. The interior of the wound dressing is connected to the outlet of the regulator. The portable topical oxygen therapy system is sized and configured to be wearable by the patient without interfering with normal ambulation.

Abstract: A portable, self-contained device is described for the topical application of oxygen and the removal of wound exudates to promote the healing of skin wounds. The device includes a wound dressing that incorporates at least one electrochemical cell for generating oxygen. The device can regulate the supply of oxygen to the wound at various concentrations, pressures and dosages and is used to produce a high concentration of oxygen at the wound site. By reversing the polarity of the power source a reduced pressure can be created in a reservoir attached to our device. The reduced pressure in the reservoir draws naturally flowing exudates away from the wound. Alternately, two reverse polarity cells are used to alternately supply oxygen and draw away exudates.

Abstract: A portable, self-contained device is described for the topical application of oxygen to promote the healing of skin wounds. The device is comprised of a wound dressing that incorporates an electrochemical, chemical, or thermal means of generating high purity oxygen. The device can regulate the supply of oxygen to an area above the wound at various concentrations, pressures and dosages. The device is driven by a built in or accessory power source. Ambient air is brought into contact with a gas permeable cathode. Oxygen present in the air is reduced at the cathode to negative ions (i.e. peroxide, superoxide or hydroxyl ions) and/or their unprotonated and protonated neutral species. One or more of these species diffuse through an electrolyte and are then oxidized at a gas permeable anode to produce a high concentration of oxygen directly above the wound.

Abstract: An electrochemical device for concentrating oxygen is provided. The electrochemical device comprises a cathode for reducing oxygen to peroxide. An anode is provided for oxidizing the peroxide to form oxygen according to a two electron process. A solid polymer electrolyte diffuses the peroxide from the cathode to the anode.
