Abstract

The invention discloses an artificial heart power pump. The artificial heart power pump comprises a blood cavity, a fluid cavity and a pulsating fluid pumping device, wherein the fluid cavity is provided with a left fluid cavity body and a right fluid cavity body; the left fluid cavity body and a left blood cavity body are separated through a left diaphragm; the right fluid cavity body and a rightblood cavity body are separated through a right diaphragm; the pulsating fluid pumping device is provided with a one-way rotating motor and two centrifugal cavities; the motor is provided with a rotating shaft and two flywheels; both the centrifugal cavities are provided with impellers capable of moving in a reciprocating mode in the axial direction; and as the impellers in the two centrifugal cavities move in the axial direction and then make contact with the flywheels alternately, a fluid flows alternately between the left fluid cavity body and the right fluid cavity body. The fluid of thepulsating fluid pumping device pushes the diaphragm to deform, so the volume of the blood cavity is periodically changed, and finally, circulating blood pumping is achieved. Blood does not need to bein contact with other parts, so the risk of blood pollution is avoided; and compared with axial flow type and centrifugal type artificial heart pumps, damage of moving parts to blood components is avoided in the invention.

Description

technical field [0001] The invention belongs to the field of medical equipment for replacing human organs, belongs to the category of artificial heart, and in particular relates to an artificial heart power pump. Background technique [0002] The heart is the power organ of the human blood circulation system. Its main function is to drive blood flow, provide sufficient blood to tissues and organs, and maintain normal metabolism and functions of the human body. The artificial heart is an advanced artificial organ that replaces the damaged heart in terms of anatomy and physiology. Its main function is to rebuild the artificial blood circulation system that adapts to the needs of human tissues and organs and physiological changes. The artificial heart can be divided into temporary, that is, an auxiliary artificial heart that partially replaces the function of the heart; long-term, that is, a total artificial heart that replaces the entire heart. [0003] Total artificial heart...
