A Review on Mock Circulatory Systems for in vitro Hemodynamic Performance Evaluation of Ventricular Assist Devices / 医用生物力学

ABSTRACT

Mock circulatory system (MCS) is an experimental platform for simulating hemodynamic performance of human circulatory system, and has been widely used in in-vitro hemodynamic performance evaluation of passive devices such as ventricular assist devices (VADs), artificial valves, as well as hemodynamic responses of mock circulation loop. MCSs are capable of simulating various physiological conditions, including health, exercise, and heart failure, by adjusting drive element of heart simulator and lumped-parameter element of vasculature components. Since 1 960 s, the research and development target of MSCs has evolved from meeting the basic performance evaluation requirement of VADs and mechanical valve to mimicking local hemodynamic characteristics in vital organs. This review summarizes the design principles, system construction of MCSs as well as its research progress and future prospects.
