Claims21
A device for supplying oxygen to a patient for treatment of a wound or condition comprising:
- a wound dressing adapted for receipt over a wound or injury treatable with oxygen;
- a portable oxygen generating device remote from said wound dressing for supplying oxygen to the skin wound, said device comprising an anode, a cathode, a power source and a phosphoric acid treated ion conducting membrane for electrochemically producing oxygen;
- a conduit fluidly connecting said oxygen generating device with said wound dressing.
A device for supplying oxygen to a patient for treatment of a wound or condition comprising:
- a wound dressing adapted for receipt over a wound or injury treatable with oxygen;
- and
- a portable oxygen generating device for supplying oxygen to the wound, said device comprising an anode, a cathode, a power source and a phosphoric acid treated ion conducting membrane for electrochemically producing oxygen.
A method for treating wounds or conditions using an electrochemical cell, comprising the steps of:
- bringing ambient air into contact with a porous cathode mounted in a housing;
- reducing oxygen present in the air to neutral species at the cathode;
- diffusing the neutral species through a ion conducting membrane to a phosphoric acid treated porous anode mounted in the housing;
- oxidizing the neutral species to oxygen at the anode;
- and
- administering a supply of oxygen from the anode to a dressing and an underlying wound or injury.
