The belt appliance includes one or more inflatable cell structures integrally formed with the belt body as an extrusion. The inflatable structures are divided into air cell pockets by means of die cutting and heat sealing operations, and the pockets are fluidically connected to an air source by an air duct which is also integrally formed with the belt body and the inflatable cells. The pockets have different configurations and vary in size, and the extrusion is fabricated from a plastic vinyl material which exhibits a low coefficient of stretchability. The inflated configuration of the cell structure is also memorized into the material whereby substantially the same inflated configuration is always obtained. Precisely defined and located contact areas, developing predetermined amounts of counterpressure, are thus present within the appliance for application to the body portions for therapeutic purposes. | |
