Abstract

A cyclically inflatable, passive motion device which includes an air pump and air reservoir to provide a supply of pressurized air without transients. The air is directed by a selector valve to one of a plurality of paths each of which has a check valve which releases at a different pressure. A four-way solenoid valve directs the pressurized air to an inflatable support. The support may have any one of a number of shapes to move different parts of the body. One embodiment used for the neck includes two saddle-like, inflatable cushion members having legs which define a yoke-like opening that fits around the user's neck. A foam rubber envelope fits over the cushion, and they all fit inside of a cover. A second embodiment of the support includes an inflatable cushion having separate compartments which are alternately inflated and deflated. The compartmentalized cushion fits in a resilient cover and may be used with a heating pad. Other cushions are designed to support and move the knee and fingers.
