含动脉分支的体循环模拟实验系统

Pulsatile Flow Simulator of Systemic Circulatory System Including Arterial Branches

本文首先建立了含分支动脉的血液体循环集中参数模型，在计算机仿真研究的基础上，设计、研制出含主要动脉分支的体循环模拟实验系统；系统由微机实施控制、数据采集与处理。实验结果表明它既可较好地模拟左心室、主动脉弓附近的血流动力学特性，同时又可较好地模拟左锁骨下动脉、挠动脉处的血流压力脉搏波基本特征。

A lumped parameter computer model of human systsmic circulatory system including arterial branches is proposed firstly. Then based upon the computer simulation and system analysis, an in-vitro pulsatile flow simulator is developed. The computer system and software are also used for on-line controlling data acquisition and processing. Results show that it can simulate the hydraudynamic Performances very well both at the model ventricle, aortic root and at the radial artery, simutuneously.
