Abstract
A pulsating medical (surgical) operating table cushion comprising an air sac array having two groups of pneumatically expandable and contractible air cells respectively communicating with one another in each of the groups. An air pump supplies air under pressure to the cells in each group through a separate conduit pipe for each respective group. Solenoid valves direct the air flow from the air pump either into the first conduit or the second conduit based upon an air supply controller. A timer provided in the air supply control circuitry changes the sequence of the air control valves after a predetermined period of time passes.
