用于心肺脑复苏(CPCR)的离心血泵的优化设计

Design and Optimization of a Centrifugal Pump for CPCR

提出了心肺脑复苏（Cardiopulmonarycerebralresuscitation，CPCR）机中重要部件──离心血泵的要求，对现有不同血系进行比较与分析，提出初步的优化方案，给出了心肺复苏用泵的优化结构，并在此基础上对自行设计研制的泵的性能进行了测试，初步实验结果表明该泵的性能良好，其水力学性能满足心肺脑复苏机的需要。

Requirements for an optimal centrifugal pump, the vital component in the equipment for cardiopulmonary cerebral resuscitation (CPCR), have been presented. The per formance of the Sarns centrifugal pump (Sarns, Inc. /3M, Ann arbor, MI, U. S. A) was tested. The preliminarily optimized model for CPCR was designed according to the requirements of CPCR and to the comparison and analysis of several c1inically available centrifugal pumps. The preliminary tests using the centrifugal pump made in our laboratory(Type CPCR-I) have confirmed the design and the optimization.
