Abstract:
Blood pumping equipment for extracorporeal circulation and ventricular assistance having:a reservoir for receiving venous blood from a patient; a pump coupled under the reservoir, said pump including a body having an internal chamber wherein a pumping means for impelling blood is arranged, a first inlet providing a passage for communicating the reservoir with the internal chamber, a first outlet; a heat exchanger for thermal conditioning of blood; a nozzle for connecting the first outlet with the heat exchanger; an oxygenator arranged downstream of the heat exchanger; said blood pumping equipment comprising: a first valve provided for in the first inlet, said first valve having a closed position for preventing blood from passing from the internal chamber to the reservoir and an open position for allowing blood to pass from the reservoir to the internal chamber; a second valve provided between the nozzle and the heat exchanger; said blood pumping equipment being connected to a computerized console for controlling operating alternatives according to any of a doctor's criterion, a plurality of measured physiological parameters of a patient and combinations thereof, for permitting independent control of pulse rate and blood flow per pulse to generate a pulsating physiological flow by the pumping means acting in combination with the first valve: the first valve being in the open position for enabling the pumping means to suck and the first valve being in the closed position for enabling the pumping means to impel.
