摘要：Airtight sacks are installed in parallel array to support a patient on a bed. Ablower supplies air to the sacks through a function control valve system and a multi-taphigh flow pressure selector. The pressure selector defines discrete zones of air pressurebetween its inlet and its exhaust to atmosphere. An adjustable tap communicating witheach sack may be selectively placed in communication with any of the pressure zones toindependently establish the pressure maintained in each sack. The sacks connect to theline from the pressure tape at a check valve connector. The function control valve systempermits, in addition to normal operation, rapid inflation of the sacks, rapid pump-down ofthe sacks, and closing of the sacks to retain air pressure for transportation. A detectorand indicator of the patient's depth of deflection is provided for at least one sack.
