Research on Testing System for Mechanical Parameters of Centrifugal Blood Bump for Extracorporeal Circulation Based on LabVIEW

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8 L/min,灌注压50 kPa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。

Abstract:

In the research and manufacturing process of the centrifugal blood pump,the flow and pressure as the two important performance 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.
