ABSTRACT:
A pulsatile pump for extracorporeal circulation in cardiosurgery is disclosed, which is constituted by a housing chamber inside which a length of an elastic hose is inserted, which chamber is fitted with two squeeze valves, one of which is for suction (i.e. mitral valve) and the other of which is for delivery (i.e. aortic valve), and with an electropneumatically actuated plate which, in the systolic step partially compresses the hose by carrying out a rototranslational movement of the plate and, in the diastolic step moves away from the hose, with an analogous opposite movement of the plate, allowing the hose to relax. A microprocessor-control system makes it possible for the pump to operate, both in manual mode and in automatic mode, also in syntony with the patient's ECG.
