The study of various impeller design for centrifugal blood pump using computer method
A centrifugal blood pump is a meaningful device for heart failure patients. However, the centrifugal blood pump causes side effects to blood for long term used; thrombosis and hemolysis, both factors relate to shear stress, therefore, the pump must be well-designed in order to decrease shear stress. Three types of impellers were designed; backward, forward and straight impeller. Each designed impellers and original impeller were compared together to determine the appropriate impeller for the blood pump.
