Abstract
The invention discloses an artificial heart system provided with a blood pressure regulation mechanism in the field of biomedical engineering. The artificial heart system comprises a blood inlet tube, a one-way valve, an air tube, an artificial heart, a blood outlet tube, blood inlet branch tubes, blood outlet branch tubes, a heart film, a volume cavity, a movable body and an elastic component, wherein the heart film divides the artificial heart into a gas cavity and a blood cavity; outlets of the blood inlet branch tubes are communicated with the right side of the blood cavity; inlets of the blood outlet branch tubes are communicated with the left side of the blood cavity; the movable body is mounted in the volume cavity and is in sealing contact with an inner wall surface of the volume cavity; and a right wall surface of the movable body is connected with a right wall surface of the volume cavity through the elastic component. When the pressure of the blood inlet tube is higher, the movable body moves rightwards, and blood entering the blood cavity is reduced; and when the pressure of the blood inlet tube is lower, the movable body moves leftwards, and the blood entering the blood cavity is increased. The artificial heart system is reasonable in design and simple in structure, and is suitable for a patient relatively sensitive to blood pressure.
