Other AbstractThe invention discloses an external-valve pulsating type blood pump, which is mainly applied to a left ventricular assist device and such occasions as extracorporeal circulation assistance, extracorporeal membrane oxygenation and the like in a cardiac surgery. According to the blood pump, valves are opened and closed in a mode of being externally clamped, so that blood circulates in a closed loop. The blood pump is composed of the two external valves, a pulsating type blood pump body, a connecting pipeline and the like. By virtue of the mode of the external valves, the blood pump can prevent the valves from getting contact with the blood, so that a series of problems caused by contact between the mechanical valves and the blood can be avoided, and thrombosis and blood injury can be relieved; meanwhile, the blood pump can be repaired and replaced conveniently; and the blood pump achieves considerable improvement on the application of existing pulsating type blood pumps.
