Embodiment
[0014] Such as figure 1 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 cardiac membrane 6, a blood vessel 9, a rotating shaft 10, a rotating plate 11, a telescopic rod 12, a control body 13, the first moving body 14, the second moving body 15, the first spring 16, the second spring 17, the connecting pipe 18, the inlet and outlet of the one-way valve 2 are respectively connected with the outlet of the blood vessel 1 at the front end and the rear end. The blood inlets of the blood vessels 3 are connected, the heart membrane 6 is arranged in the artificial heart 4, the heart membrane 6 divides the artificial heart 4 into two parts, the gas cavity 7 and the blood cavity 8, the trachea 5 communicates with the gas cavity 7, and the rear end enters the The bleeding port of the blood vessel 3 and the blood inlet port of the outlet blood vessel 9 are all connected with the blood c...

The invention provides a heat film separating type artificial heart, and belongs to the technical field of medical apparatuses and instruments. The heat film separating type artificial heart comprises a blood feeding tube, an one-way valve, an air tube, an artificial heart body, a blood discharging tube, a heart film, a rotating plate, a control body, a moving body, springs and a connecting tube; an air cavity, a blood cavity and a rotating shaft are embedded on the upper wall surface of the vessel through the heart film; the first spring is arranged between the left wall surface of the first moving body and the left wall surface of the control body; the second spring is arranged between the lower wall surface of the second moving body and the lower wall surface of the control body; one end of the connecting tube communicates with the blood feeding tube at the front end and while the other end of the connecting tube communicates with a storing cavity in the left side of the first moving body; when the blood feeding tube at the front end is at relatively high pressure, the rotating plate clockwise rotates, and the blood entering the blood cavity is reduced; when the blood feeding tube at the front end is at relatively low pressure, the rotating plate anticlockwise rotates, and more blood enter the blood cavity. The heat film separating type artificial heart is reasonable in design, simple in structure, and suitable for artificial heart system of a patient sensitive to blood pressure.
Description
technical field [0001] The invention relates to an artificial heart system in the technical field of medical devices, in particular to a heart membrane split type artificial heart 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 ...
