Abstract:
A portable, self-contained device is described for the topical application of oxygen and the removal of wound exudates to promote the healing of skin wounds. The device includes a wound dressing that incorporates at least one electrochemical cell for generating oxygen. The device can regulate the supply of oxygen to the wound at various concentrations, pressures and dosages and is used to produce a high concentration of oxygen at the wound site. By reversing the polarity of the power source a reduced pressure can be created in a reservoir attached to our device. The reduced pressure in the reservoir draws naturally flowing exudates away from the wound. Alternately, two reverse polarity cells are used to alternately supply oxygen and draw away exudates.
Abstract:
An apparatus (10) for removing oxygen from an enclosed environment (E) includes an electrolyzer (60) operable to remove oxygen from the environment and a zinc-air battery (20) for powering the electrolyzer and removing oxygen from the environment.
Abstract:
A device for delivering oxygen to a wound or injury includes a bandage, which includes a base defining an opening, a cover, and a locking mechanism for releasably securing the cover to the base. An oxygen source is in fluid communication with the cover, whereby oxygen is delivered to the opening in the base.
Abstract:
A device is disclosed for the application of oxygen to promote wound healing and tissue repair. The device includes a portable oxygen generating device for delivering oxygen to the wound site. The oxygen generating device generates high purity oxygen through electrochemical means and includes a cathode, an anode, and a phosphoric acid treated ion conducting membrane. The oxygen generating device may be driven by a power source which supplies current to the anode and cathode. Oxygen in the ambient air is reduced to water and/or peroxide in neutral or ionic forms. One or more of these species diffuse through the ion conducting membrane and is oxidized at the other electrode to produce high purity oxygen.
