The invention discloses a flow adjusting type blood pressure stabilizing system belonging to the technical field of medical instruments. The system comprises blood inlet tubes, a one-way valve, an air tube, an artificial heart, a blood outlet tube, a heart thin film, a rotary board, a control chamber, movable plates, a movable body, springs and adjusting tubes. One end of the first adjusting tube is communicated with the front-end blood inlet tube, and the other end of the first adjusting tube is communicated with the chamber between the first movable plate and the second movable plate. One end of the second adjusting tube is communicated with the blood outlet tube, and the other end of the second adjusting tube is provided with two outlets respectively communicated with the chamber on the right side of the first movable plate and the chamber on the left side of the second movable plate. When the pressure of the front-end blood inlet tube is relatively high, the rotary board rotates counterclockwise, and the blood entering a blood chamber is decreased. When the pressure of the front-end blood inlet tube is relatively low, the rotary board rotates clockwise, and the blood entering the blood chamber is increased. The flow adjusting type blood pressure stabilizing system is reasonable in design, simple in structure, and suitable for an artificial heart system for 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 flow-regulating blood pressure stabilizing 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...
