Abstract
An apparatus capable of automatically exchanging helium gas filling a balloon pump inserted in the aorta of a patient. The apparatus comprises a pressure generator producing positive pressure and negative pressure, an electronic control unit, an electrocardiograph, and a helium supply and discharge device. The positive and negative pressures produced by the pressure generator are alternately supplied to the balloon pump. The timer measures the time for which the pressure generator operates. The electronic control unit operates in response to the output signal from the timer and exchanges the helium gas with new helium gas whenever the the pressure generator operates the balloon pump for about 2 hours.
