ABSTRACT:
A self-propelled wheelchair type artificial heart driving apparatus for giving freedom of movement to those patients who require an auxiliary artificial heart. Various safety devices are provided to avoid danger due to erroneous running of the wheelchair at the time when the patients board on or alight from the wheelchair and after alighting therefrom. For the purpose of enlarging a sphere of movement of the patients and preventing possible dangers, a motor-operated tube taking-up mechanism is provided and the wheelchair is permitted to run only when the tubes are in the orderly housed condition. A pressure compensating solenoid valve is provided in parallel to a pressure adjusting solenoid valve and a tank is dispensed with so as to make reduction in size of the artificial heart driving apparatus.
