ABSTRACT:
A closed loop feedback-controlled air supply system for air support convalescent beds having groups of air sacs for supporting various body sections of a patient. The air supply system may be self-contained with its own air supply compressor or it may utilize any other source of compressed air. The air supply is coupled with a distributor manifold from which extends a plurality of air supply lines extending to selected groups of air sacs. Servo valves controlling each of the air supply lines are automatically positioned and controlled by signals from a microprocessor, the microprocessor receiving pressure feedback monitoring signals from pressure transducers associated with each of the groups of air sacs. Between the air supply and the manifold may be provided a master control valve which may be a servo valve also activated and controlled by the microprocessor responsive to feedback signals. Where the air supply is provided by a variable speed compressor, the compressor may also be responsive to control signals from the microprocessor.
