The paper provides the results of an experimental study of domestic artificial EMIKS disk cardiac valves during simulated pulsing flow. The operation valves was examined in the aortic position by photochromic visualization. The patterns of flow velocities beyond the valves during the whole operating cycle were obtained. The models of EMIKS valves at opening angles of 65 degrees and 80 degrees and the model with acoustic clearance in the design of a disk movement stopper were exploded. The findings may be useful for cardiac valves designers in evaluating the impact of designing features of a valve on its hydrodynamic characteristics.
本文提供了国产人工EMIKS盘式心脏瓣膜在模拟脉动流期间的实验研究结果。通过光致变色可视化技术在主动脉位置对运行中的瓣膜进行了检查。获得了整个运行周期内瓣膜下游的流速模式。对开度为65度和80度的EMIKS瓣膜模型以及盘式运动限位器设计中具有声学间隙的模型进行了剖析。这些研究结果可能对心脏瓣膜设计者评估瓣膜设计特征对其流体动力学特性的影响有用。
