ABSTRACT
In order to study the cardiovascular hemodynamic characteristics and evaluate the artificial heart, especially the compression cardiac assist devices, we put forward a simulating device which is made of pump, valve, tubes and controller, and can be used to imitate cardiovascular system. Moreover, in this essay, we put forth an algorithm to draw pressure-volume loop with the parameters measured, including liquid pressure, volume and air pressure. The changes in the frequency and duty of control signal and in the angle of proportional valve can symbolize cardiovascular system in different heart rates, with different systole period, and at different level, respectively. The result of simulating device experiment proved to be coincident with physiology.
