摘　　要：本义在阐述体外循环原理及临床意义的基础上,简单介绍了体外循环用血泵的原理、特点以及关键技术评价指标,重点分析了离心血泵的发展历史,及二代、三代离心血泵磁力驱动的工作原理和特点。第二代血泵采用圆盘形磁力耦合器驱动方式,其永磁体采用组合拉推式结构。第三代血泵是在第二代血泵的基础上增加了磁悬浮系统。最后展望了体外循环用离心血泵的发展趋势。This paper describes the principle and clinical significance of extracorporeal circulation, briefly introduces the principles and characteristics of the blood pump for extracorporeal circulation, and the key technical evaluation indexes of the blood pump. The paper focuses on the development history of centrifugal blood pump, the working principle and features of the second-generation, the third-generation magnetic drive blood pump. The second-generation blood pump uses disc-shaped magnetic coupler whose permanent magnet adopts the structure of push-pull combination. The third-generation blood pump based on the second one is added the suspension system, including electromagnetic levitation and permanent magnetic levitation at present. Finally this paper prospects for the development trend of the centrifugal blood pump for extracorporeal circulation.
