Radial pulsation simulator with blood circulatory method of left atrium and left ventricle and method for simulating radial pulsation based on pressure feedback

摘要

TECHNICAL FIELD The present invention relates to an ultrasound pulsating flow generating device, an artificial pulse wave reproducing system having the pulsating flow generating device, and a reproducing method. The present invention relates to an apparatus for generating a pulsatile flow by simulating the left ventricle of a heart in a system for reproducing an artificial pulsation wave, the apparatus comprising: an inflow end into which a circulating fluid flows into an internal space; A left ventricular cylinder having a discharging end through which the fluid is discharged; A left ventricular linear driving unit for linearly reciprocatingly driving the piston; An inflow check valve having a specific opening pressure for functioning as a left atrive ventricular valve provided at an inlet end of the left ventricular cylinder; And a discharge check valve having an initial flow resistance and having a specific discharge pressure so as to function as an aortic valve provided on one side of the discharge end of the left ventricle cylinder, wherein the discharge check valve is spaced apart from the inner space of the left ventricle cylinder and the outer surface of the left ventricular piston Precision pulsating flow generating device.
