Bandage or plaster for the topical application of oxygen to promote the healing of skin wounds

摘要

A device for modulating a supply of oxygen for topical treatment of skin wounds comprises a wound dressing patch adapted for receipt over a skin wound treatable with oxygen and an oxygen regulating device incorporated within the wound dressing patch form modulating a supply of oxygen to skin wound. The oxygen regulating device can generates oxygen electrochemically and includes a cathode for reducing oxygen in a feed gas to negative ions and/or neutral species; an electrolyte for diffusing the negative ions and/or neutral species therethrough; and an anode communicating with the electrolyte for oxidizing the negative ions and/or neutral species to produce a high concentration oxygen for supply to the skin wound.
