Embodiment

[0017] Such as Figure 1 to Figure 6 As shown, the present invention includes a front-end blood vessel 1, a one-way valve 2, a rear-end blood vessel 3, an artificial heart 4, a trachea 5, a heart membrane 6, a blood vessel 9, a control cavity 10, a stretch rod 11, a rotating rod 12, Rotary shaft 13, regulating tube 14, rotating plate 15, first moving plate 16, second moving plate 17, first spring 18, second spring 19, moving body 20, third spring 21, the inlet and outlet of check valve 2 The openings are respectively connected with the bleeding port of the front end blood vessel 1 and the blood inlet port of the rear end blood vessel 3. The heart membrane 6 is arranged in the artificial heart 4, and the heart membrane 6 divides the artificial heart 4 into gas chamber 7 and blood chamber 8. Partly, the trachea 5 communicates with the gas chamber 7, the bleeding port of the blood vessel 3 at the rear end, and the blood inlet port of the blood vessel 9 communicate with the blood ...

Abstract

The invention relates to the technical field of medical instruments and provides a blood flow blocking and releasing device comprising blood inlet tubes, a check valve, an air tube, an artificial heart, a blood outlet tube, a heart film, a rotating plate, a control cavity, moving plates, a moving body, a spring and an adjusting tube. The heart film divides the artificial heart into an air cavity and a blood cavity; the moving plates and the moving body are disposed in the control cavity; the lower end faces of the moving plates are matched with the upper end face of the moving body; one end of the adjusting tube is communicated with a front end blood inlet tube and the other end of the adjusting tube is communicated with a cavity between the first moving plate and the second moving plate. When the pressure of the front end blood inlet tube is relatively high, the rotating plate rotates anticlockwise and blood entering the blood cavity reduces; when the pressure of the front end blood inlet tube is relatively low, the rotating plate rotates clockwise and blood entering the blood cavity increases. The blood flow blocking and releasing device is reasonable in design and simple in structure and is suitable for an artificial heart system for patients sensitive to blood pressure.

Description

technical field [0001] The invention relates to an artificial heart system in the technical field of medical equipment, in particular to a blood flow blocking device 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 ...
