Abstract

PURPOSE:To automatically perform air feed operation in succession to water feed operation, by mounting a control means for driving a water feed means to feed water and subsequently driving an air feed means automatically for a predetermined time. CONSTITUTION:In a water feed operation, since a flow control valve 38 is held to a closed state and a normally closed flow control valve 26 is closed, the pressures in both of a connection pipe 24 and a liquid feed tank 22 rise by the open air stream supplied from an air feed pump 30 and water or a physiological saline solution flows in water feed pipes 20, 6 to be supplied in the body cavity. In air feed operation, a flow control valve 26 is held to a closed state and the flow control valve is also held to a closed state and an open air stream is supplied in the body cavity from the air feed pump 30 through air feed pipes 18, 6. The feed of air started after water is fed is performed for a definite time, because a trigger detection circuit 102 is actuated at the falling of the water feed signal continuously supplied from a time width generating circuit 100 and a time width generating circuit 108 continuously supplies an air feed signal to valve driving circuits 90, 92 for a predetermined time after the feed of water.
