Abstract: A cellular patient support for therapeutic air beds according to the present invention for comprises an air cell container forming a plurality of air cell receptacles disposed in side-by-side relation. A plurality of low air loss air cells are removably positioned within respect ones of the air cell receptacles. An elongate air supply manifold extends along the length of the air cell container and is connected in air supplying relation with each of the air cells. Each of the connectors for the air cells is provided with a pressure control orifice which controls the respective pressure of the air cells and the air supply manifold in relation to the air delivery pressure of the air supply manifold. The air cells are removable from the air cell container and thus the container structure is capable of being efficiently cleaned to enhance the therapeutic aspect of the air bed system.

Abstract: A convalescent chair for hospital and nursing home patients and the like including a chair structure forming a back rest, arm rests and shoulder and head support for patients. A seat support structure is pivotally connected to the forward portion of the chair structure and is elevated by a motorized jack from a substantially horizontal position to an inclined position to assist in raising a patient from the seated position to the standing position. A plurality of air sacs and a therapy pad are supported by the seat support structure and are supplied filtered and cooled air to provide sufficient air flow for inflation of the air sacs and for effective discharge of air from the upper portion of the air sacs. An air distribution conduit extending from a blower to an air supply manifold in assembly with the seat support structure forms a heat exchanger portion so that air being drawn through an internal chamber of the chair by an exhaust fan imparts cooling to air flowing through the air distribution conduit.

Abstract: Fluidized hospital bed is provided incorporating a segmented, adjustable patient support structure having a plurality of flexible air impervious air bags releasably secured thereto. An air supply is provided for maintaining controllable inflation of selected groups of the air bags with air pressure therein being selectively and automatically adjustable for patient comfort and for emergency patient care. Each of the air bags has a single air inlet in communication with the air supply and multiple air vent holes along the upper side portions thereof or ventilation, patient heating or cooling and removal of moisture. Convex upper surface portions of the air bags facilitate support of the patient without wrapping of air bag material about the patient. The fluidized hospital bed system is powered electrically with both AC and DC current, enabling battery overide in the event of failure of the AC power supply.
