摘要： A device is described for promotion of human or animal wound healing by controlling oxygen concentration in the environment around the wound. It is light weight, portable, convenient and comfortably worn by the patient. It can operate continuously or intermittently and can patient-controllable or automatic. Its comfort, portability and effectiveness insure that it will be readily used by patients to enhance recovery from skin trauma. The device is a generally flat unit which includes components for electrochemical production of an ionic species at one electrode, transported of the ionic species across an ion permeable membrane, and reaction of the ionic species at a second electrode to be converted to a molecule which results in a net change of concentration of oxygen adjacent to the wound. Medication may also be applied to the wound within the enclosure. The electrical system can powered by an easily replaceable battery. The patient contact portion of the device unit in normally discarded after a single use, and the electrical and membrane components, contained in their own housing, are reused. A method of enhancing wound healing by controlling the concentration of oxygen in the vicinity of a wound using the device is also described.
