J0207-1-2 Study of centrifugal blood pump test equipment for extracorporeal circulation

Abstract

The characteristics of the blood pump for the extra-corporeal circulation is affected by the resistance of the blood circuit as well as fluctuating in biological circulation. In this study, an extra-corporeal circulation simulator has been developed. This extra-corporeal circulation system can automatically simulate the fluctuating blood pressure and vascular resistance, successively. Moreover, it can change the rotational speed periodically. The steady and unsteady characteristics of this simulator are examined.
