Abstract: A topical hyperbaric therapy device is provided for treating skin disorders and for administering pressurized therapeutic gas (e.g., hyperbaric oxygen) to an afflicted region of a patient's skin. In particular, the topical hyperbaric therapy device of the present invention comprises an inflatable and generally toroidal-shaped tube having a top portion, a bottom portion, and an open interior portion. In addition, a pliable pad member is sealably joined to the bottom portion of the tube. In use, the pliable pad member and the open interior portion of the tube define an enclosed chamber when the tube is inflated and top portion of the tube is sealably constrained against the patient's skin. The topical hyperbaric therapy device also includes an inlet port for supplying pressurized therapeutic gas to the enclosed chamber, and an outlet port for venting pressurized therapeutic gas from the enclosed chamber once the pressure therein becomes greater than a predetermined level.
