Abstract
In recent years, blood pumps are used as alternative therapy of heart transplant, however, the characteristics is affected by the biological circulation dynamic state. In this study, a load testing machine for blood pumps have been developed with the aim of clarifying the blood pump evaluation criteria. This simulator has capability to reproduce biological circulation of a cardiac pulsation, blood pressure fluctuation and blockage of blood vessel. The water solution of glycerol is used as working fluid in order to simulate human blood in this paper, and evaluation and examination of a simulator are performed from the centrifugal blood pump response.
