Abstract: An air support system suitable as a hospital bed comprises a plurality of contiguous, inflatable cells 2. A blower 25 supplies inflation air to the cells. The blower 25 is driven by an electric motor 26 and solenoid valves 29, 50 operate automatically, in the event of electrical power failure, to seal-off inflation air present in the cells. Three-position spool valves 72-74 each operate to direct the flow of cell inflation air through a selected one of three alternative paths.

Abstract: Medical patients, such as those having burns or bed sores, are supported fully or in part by this fluid system, which is available in many embodiments. All embodiments are directed to reducing local bearing pressure on body tissue. Multiple flexible elements or cells of differing embodiments are filled with a pressurized fluid, usually air. These multiple flexible cells are generally supported on a fully adjustable hospital bed frame.When all the cells are inflated by internal fluid pressure, upper portions of the cells contact one another to form an overall seal which substantially prevents the escape of any fluid under equal or lower pressure, which may be thereafter introduced into the spaces between the lower portions of the cells. By using selective fluid pressurization and supply systems, automatic valving action occurs whereby the patient's body weight is beneficially distributed and supported on fluid, substantially reducing the values of supporting pressures.
