Abstract: An artificial heart system combined with electrostatic pumps and pressure mechanical valves is designed in this paper. The feasibility of open-heart surgery is studied by using external electrostatic pumps and unidirectional minimum pressure mechanical valves to replace mitral valve, tricuspid valve, aortic valve and pulmonary valve. The working principles of electrostatic pump and mechanical valve is introduced. The connection scheme of pumps, valves with organs of human body is provided. The calculation of related parameters of pumps and valves in the condition of blood pressure extremes is completed. The system is characterized by numerical consistency with changes of blood pressures in the corresponding organs of the heart and has a good application prospect.
Key words: electrostatic pump; unidirectional minimum pressure mechanical valve; artificial heart system; blood pressure; extracorporeal circulation; heart surgery
