Abstract:
1. An auxiliary artificial heart pump drive device for driving an auxiliary artificial heart pump, the pump drive device comprising: a pump drive processing circuit; first and second pump control parts arranged in duplexed configuration, each pump control part configured for controlling the auxiliary artificial heart pump by outputting a drive signal to the auxiliary artificial heart pump, wherein when a normal state is detected by the detection circuit of the first pump control part, the switch circuit and the power source switch of the first pump control part are set in a conductive state by the pump drive processing circuit and the switch circuit and the power source switch of the second pump control part are set in a cut-off state by the pump drive processing circuit, and when the failure state is detected by the detection circuit of the first pump control part, the switch circuit and the power source switch of the first pump control part are set in the cut-off state by the pump drive processing circuit and the switch circuit and the power source switch of the second pump control part are set in the conductive state by the pump drive processing circuit.
