摘　　要：在离心血泵的研制过程中,流量与灌注压作为血泵的两个重要性能指标,是关键的检测参数;而扭矩是离心血泵驱动能力的重要体现,因此,对扭矩的测试也至关重要;针对离心血泵流量8L/min,灌注压50kPa的设计要求,设计了基于虚拟仪器技术的离心式血泵压力、流量和扭矩的测试系统,为实现离心式血泵的测试、分析和优化提供重要的试验方法;结果表明:该测试系统能够满足对离心血泵流量、压力和扭矩等机械参数进行测试的要求。In the research and manufacturing process of the centrifugal blood pump, the flow and pressure as the two important perform- ance indicators, are the key testing parameters; and the torque is capable of driving for the centrifugal blood bump, therefore, the torque testing is also crucial. This paper designs a testing system for the flow. pressure and torque of the centrifugal blood bump based on virtual instrument technology, and provides a important test method for blood bump＇s testing and analysis. The result shows that： the test system can satisfy the testing requirements for measurement parameters.
