Artificial heart system provided with blood pressure regulation mechanism

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.

Description

technical field [0001] The invention relates to an artificial heart system in the field of biomedical engineering, in particular to an artificial heart system with a blood pressure regulating mechanism. Background technique [0002] The artificial heart is to partially or completely replace the pumping function of the heart with biomechanical means to maintain blood circulation throughout the body. Divided by function, it includes ventricular assist blood pump and total artificial heart. Artificial heart transplantation is a means of treating heart failure and an effective alternative to heart transplantation. A total artificial heart is a device used to replace the lower two chambers of the heart. These two replaced chambers are called "ventricles". This device may be used if a patient has advanced heart failure where both ventricles are no longer functioning. Heart failure is the inability of the heart to pump enough blood to meet the body's needs because it is damaged...

Problems solved by technology

[0003] After searching the existing technical literature, it was found that Chinese Patent No. 99126700.1, patent name: gas-electric integrated blood pump, gas-electric integrated artificial heart, this patent technology provides a solution for simplifying the blood pump and miniaturizing the artificial heart, but it Cannot effectively adjust the bleeding pressure of the artificial heart out of the blood vessel, which will easily cause the patient's blood pressure to fluctuate greatly
