PURPOSE: To provide one continuous rotary blood pump with good efficiency for common use to exhibit functions of both right and left system of the heart.
CONSTITUTION: When an electronic control device 4 controls switch valves 2a, 3a to be opened and valves 2b and 3b to be closed, blood from the right atrium of the heart is sucked and discharged by a pump 1 through the valve 2a and subsequently supplied to the lung artery through the valve 3a. At this time, the valves 2b, 3b are closed, so that the left atrium and the main artery are intercepted. On the contrary, the electronic control device 4 controls the valves 2b, 3b to be opened and the valves 2a, 3a to be closed, blood from the left atrium is sucked and discharged by the pump 1 through the valve 2b and subsequently supplied to the main artery through the valve 3b. At this time, the valves 2a, 3a are closed, so that the right atrium and the lung artery are intercepted. By repeating the above operation, the right heart function and the left heart function are alternately exhibited.
