人工心瓣脉动流试验中,主动脉根部压力、流量波形重建的实验研究

Reconstruction of the Pressure and Flow Waves at Elastic Aortic Root in In-vitro Pulsatile Flow Testing of Artificial Heart Valves: Experimental Study

本文针对目前国内外在人工心瓣体外脉动流试验中,难以直接、准确地检测模拟主动脉根部压力、流量波形的状况,对可能导致的测试结果非客观、可比性问题进行了脉动流实验研究,并依据前文所建立的理论方法,对在现有人工心瓣体外脉动流检测装置上重建可消除测点后移误差的主动脉根部压力、流量波形,进行了流体力学实验模拟研究。

In order to solve the problem in the artificial heart valve in-vitro pulsatile flow testing, that the pressure and flow waves at the resilient aortic root can not be measured directly and accurately > we made an experimental study on the basis of the numerical method which we had presented in the ref[2]of this paper.
