心脏辅助与替代装置中的血泵

背景：心脏替代型血泵得到迅速地发展,不仅在结构上具有便携辅助式或体内植入式,性能上也通过了几代的改进而具有良好的生理相容性。目的：介绍心脏可视化手术中人工心肺机用血泵,心脏终末治疗时机械替代用的各种辅助血泵和全人工心脏,并展望人工心脏未来发展的趋势。方法：应用计算机检索维普数据库、IEEE Xplore数据库、Springer Link数据库及谷歌学术进行检索并参考相关书籍,以＂血泵＂、＂人工心脏＂为关键词,选择内容相关的文献。结果与结论：共纳入43篇文献。血泵为实现心脏直视手术及心脏的终末治疗提供了可能性,有非常高的临床价值。但血泵从结构设计和控制方面都有待提高,其中做到血泵用材料与人体具有良好的生理相容性及生理参数的控制系统是目前血泵发展的关键问题。

Blood pump in heart assistant and replacement devices

BACKGROUND： The blood pumps for heart replacement have rapidly developed. They are not only structurally classified as portable auxiliary type or implantable type, but also have good physical compatibility in performance after generations of improvement. OBJECTIVE： To introduce the blood pump of a heart-lung machine used in heart visualization operation, various assist blood pumps for mechanical replacement during heart terminal treatment, and the total artificial heart. And to look forward the development trend of artificial hearts in future. METHODS： The VIP database, IEEE Xplore Database, Springer Link Database, Google Scholar and related books were retrieved for articles by computer. The key words were ＂blood pump, artificial heart＂. RESULTS AND CONCLUSION： A total of 43 articles were included. Blood pump offers possibility for the realization of the heart visualization surgery and has a very high clinical value. But the structure design and control system are need to be improved, while good biocompatibility materials for manufacture and control system of physiological parameters remain the key points for the development of blood pump.
