Oxygen producing bandage and method

A method for treating skin wounds using an electrochemical cell, comprising the steps of:

• bringing ambient air into contact with a gas permeable cathode;
• reducing oxygen present in the air to negatively charged ions or neutral species at the cathode;
• diffusing the negatively charged ions or neutral species through an electrolyte to a gas permeable anode;
• oxidizing the negatively charged ions or neutral species to oxygen at the anode;
• and
• modulating a supply of oxygen to a skin wound.

A method for treating skin wounds, comprising the steps of:

• placing an oxygen generating wound dressing patch over a skin wound, a power source supplying energy to the patch;
• bringing air into contact with a cathode incorporated in the wound dressing patch;
• reducing oxygen present in the air to negative ions or neutral species at the cathode;
• diffusing the negative ions and/or neutral species through an electrolyte to an anode, the electrolyte and anode incorporated in the wound dressing patch;
• converting the negative ions and/or neutral species to dioxygen at the anode;
• and
• passing the dioxygen out the anode to the skin wound.

A method for treating skin wounds, comprising the steps of:

• placing an oxygen generating wound dressing patch over a skin wound;
• generating oxygen within the wound dressing-patch;
• and
• supplying oxygen to the skin wound.

A device for supplying oxygen to a skin wound, comprising:

• a dressing adapted for receipt over a skin wound treatable with oxygen;
• and
• an oxygen generating device incorporated within the dressing for supplying oxygen to the skin wound electrochemically including:
• 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 of oxygen for supply to the skin wound.
