ABSTRACT:
A portable chamber for enclosing a portion of the body for treatment with oxygen or other gas at pressures slightly above atmospheric and the control circuits for operating the chamber are disclosed. In its basic configuration, the chamber of the invention is designed to enclose a portion of the body, such as a leg or arm, but can be enlarged to enclose the entire body, except the head of the patient. In its basic design, the chamber of this invention is constructed in two parts that mate to form the chamber. When mated, one end of the chamber is closed and the other end is open to receive the part of the body being treated. The open end contains a sleeve that encircles the body part being treated to form an air tight seal. A gasket arrangement is provided to seal the two parts when mated. The control circuits or elements are fluidic elements. These fluidic elements are housed in a control box and coupled to the chamber by means of appropriate couplers mounted on the closed end of the chamber. A humidifier is also attached to the closed end of the chamber on the outside of the chamber.
