Oxygen Generation Apparatus and Method

Abstract

An oxygen generator for an oxygen-generation apparatus has a proton-conducting membrane (60), a cathode (50) contacting a first side, or cathodic side, of the membrane, an anode (70) contacting a second side, or anodic side, of the membrane, and a source of water for supply to the membrane. In use, an electrolysis voltage applied between the cathode and the anode causes electrolysis of the water to generate oxygen gas at the anode. Atmospheric oxygen, i.e. oxygen in the air, is substantially prevented from coming into contact with the cathode. For an acidic proton-conducting membrane this substantially prevents the formation of hydrogen peroxide at the cathode.

Description

[0001]The invention relates to an oxygen generation apparatus and a method of generating oxygen. In particular, it is concerned with the generation of oxygen for use in the treatment of wounds and sores. However, it will be clear to those skilled in the art that the invention also has many other applications requiring oxygen or hydrogen generation. However, it will be clear to those skilled in the art that the invention also has many other applications requiring oxygen or hydrogen generation.[0002]There is evidence in the literature that the supply of oxygen to a wound site can promote the healing of the wound. This applies to both humans and animals. Topical oxygen therapy, as it is known, encourages the growth of fresh skin tissue to close and heal wounds. It is believed that oxygen dissolves in tissue fluids and improves the oxygen content of the intercellular fluids.[0003]Various methods have been described for the supply of oxygen to wounds. In some instances, the affected limb...

AI Technical Summary

Benefits of technology

[0002]There is evidence in the literature that the supply of oxygen to a wound site can promote the healing of the wound. This applies to both humans and animals. Topical oxygen therapy, as it is known, encourages the growth of fresh skin tissue to close and heal wounds. It is believed that oxygen dissolves in tissue fluids and improves the oxygen content of the intercellular fluids.

[0032]Advantageously, an oxygen generator embodying the invention may be designed for use in any orientation. This may enhance portability of the oxygen generator.

Problems solved by technology

This approach is impractical for many patients as it restricts the mobility of the patient and necessitates the use of control valves to control the flow of oxygen.

Furthermore, when healthy skin is exposed to gasses containing high concentrations of oxygen, it is possible that vasoconstriction and tissue destruction may occur.

The presence of hydrogen peroxide is not welcomed by physicians as it can kill healthy cells.
