  • Pump driving unit for driving a pump used for supporting or substitution of cardiac function
    Patent number: 7244224
    Abstract: In a small sized pump driving unit, a fluid pump is used for driving the pump for supporting of substituting of cardiac function. The fluid pump can generate pressure fluctuations that can generate pulsation of the pump for supporting or substituting of cardiac function and produces sufficient performance to drive the pump unit.
    Type: Grant

  • Device for driving blood pumps
    Patent number: 6709383
    Abstract: A blood pump driving device which is capable of making a blood pump 10 free from an unbalance between loads when sucking and discharging, respectively and which makes it possible to eliminate a sensor positioned close to a patient, is made up of an oil reservoir 30 including therein a gas chamber 33 and a liquid chamber 32, an oil pump 20 for pumping out a liquid stored in the liquid chamber 32 of the oil reservoir 30 to the blood pump 10, and a pressure accumulating chamber 34 storing therein a gas pressure of the gas chamber 33 of the oil reservoir 30 by being brought into fluid communication with the gas chamber 33 of the oil reservoir 30.
