Abstract
An auxiliary artificial heart pump drive device for driving an auxiliary artificial heart pump includes first and second pump control parts which are arranged in duplexed configuration. Each pump control part controls the auxiliary artificial heart pump by outputting a drive signal to the auxiliary artificial heart pump. Each pump control part has a means which, when a failure is detected in the pump control part, electrically cuts off a path through which the drive signal is outputted to the auxiliary artificial heart pump. According to the present invention, it is possible to provide an auxiliary artificial heart pump drive device and an auxiliary artificial heart system which exhibit high availability even when a serious failure occurs by any chance without duplexing a pump device.
