- 摘要：
PROBLEM TO BE SOLVED: To maintain the diastole augmentation function so as to increase blood flow to the coronary artery by generating pulsatile flow in synchronization with the systole and diastole of a patients own pulse during auxiliary circulation therapy administered to a patient under cardiac dysfunction, and also to improve the therapeutic effect of intending to restore cardiac function without applying after-loading to the heart.
SOLUTION: Pulsatile flow generation control device Y incorporated in a pulsation-type auxiliary circulation system X as an apparatus system having an electromagnetic valve 7 in blood supply lines (4, 6, 8) on the delivery side of artificial lung 5 and a control means 11 for performing control-output relating to the opening and closing operation of the electromagnetic valve 7. The control means 11 has at least a delay circuit and is such that the electromagnetic valve 7 is actuated to close and is maintained closed for a predetermined time interval based on delay detection and is actuated to open based on delay cancellation so that blood flow is periodically interrupted.
