摘　　要：制定系统、全面地评价连续流动式左心辅助泵的体外评价体系,研制用于轴流血泵体外测试的试验台,制定试验方法,使之稳定可靠地评价轴流血泵的设计与加工是否满足性能要求,指导动物实验与临床应用。根据连续流动式左心辅助泵的设计、制造和临床要求制定体外评价内容,按照评价内容设计制作适合于轴流式左心辅助泵结构特点的流体性能试验台、耐压试验台、寿命试验台和溶血试验台。实验分析结果显示,所制定的体外评价体系的评价内容全面,能比较完备地评价连续流动式左心辅助泵,并具有较高的精度与可靠性。This study is aimed to establish a system of systematically evaluating the continuous flow left ventricular assist device （ LVAD ） in vitro. The test platform was designed and manufactured for axial blood pump. And the test protocols were established. The in vitro evaluation were made according to the need of continuous flow LVAD design, manufacture and clinical requirement. The platform consisted of the testing on hydrodynamic characteristic, pressure-proof, life and hemolysis characteristic of axial left ventricular assist pump. The accuracy and reliability of the testing were confirmed through experiments. It was showed that the evaluation system was comprehensive and reliable in evaluating the continuous flow LVAD.
