人工辅助心脏是除心脏移植外唯一有效的终末期心脏衰竭治疗方法,是高端医疗器械生产领域的代表.本文介绍一种基于磁液双悬浮技术的第三代人工辅助心脏系统构成并对各分系统工作原理进行说明,最后利用本文研究的人工辅助心脏系统完成了体外溶血实验以及动物实验并取得了较好的效果.

This paper presents a new maglev and hydrodynamic suspended centrifugal blood pump, the basic structure and working principle of the product are introduced. The simulation analysis of the internal flow field of the blood pump based on Ansys CFX is carried out. Also the simulation results are verified by means of experiments, then the theoretical basis for the design and improvement of magnetic liquid suspension centrifugal blood pump is put forward. At present, the product has achieved great progress.

Magnetic fluid suspension centrifugal blood pump is the core component of the third generation assisted heart system.The performance of the blood pump is a very important parameter of the assisted heart system.In this paper,we study the performance of a new kind of magnetic fluid suspension centrifugal blood pump by designing an experimental system and evaluating this blood pump,providing the experimental data for the research of the magnetic fluid suspension centrifugal blood pump.
