Abstract:
Objective The research of impeller blood pump has been the key point in cardiac surgery and biomedical engineering fields in recent years. To investigate hydrodynamies of self researched and developed mini axial flow pump, parameters of pump were tested on a homemade mimic vitro platform. Methods Hydrodynamics tests were performed in vitro mimic circulation, water and 30% glycerin in water as respeetive circulatory mediator to simulate blood. Results Flow rates can reach 6. 19L/min and 5.08L/min respectively in water and 30% glycerin, when rotation speed was 13000rpm and pressure was 100mmHg. Conclusion Axial flow blood pump has good hydrodynamics to substitute for left ventricle, whieh can meet the demand of assisted circulation in congestive heart failure patients.
