A blood pressure self-stabilizing device belonging to the technical field of medical equipment comprises a blood inlet tube, a check valve, an air tube, an artificial heart, a blood outlet tube, a heart film, a rotary plate, a control body, moving bodies, springs and a connecting tube; the artificial heart is divided into an air cavity and a blood cavity by the heart film; a first spring is arranged between the left wall side of a first moving body and the left wall side of the control body; a second spring is arranged between the lower wall side of a second moving body and the lower wall side of the control body; one end of the connecting tube is communicated with a front-end blood inlet tube and the other end is communicated with a volume cavity at the left side of the first moving body. When the pressure of the front-end blood inlet tube is higher, the rotary plate rotates clockwise and the blood entering the blood cavity is reduced; when the pressure of the front-end blood inlet tube is lower, the rotary plate rotates anticlockwise and the blood entering the blood cavity is increased. The blood pressure self-stabilizing device is rational in design, simple in structure and applicable to an 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 equipment, in particular to a blood pressure self-stabilizing 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 be...
