摘要:
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. Oxygen can also be depleted from that same area by reversing the polarity of the power source allowing the supply of oxygen to the wound to be modulated, thereby controlling the rate of healing.
