The invention discloses an artificial heart with a one-way valve, and belongs to the technical field of medical instruments. The artificial heart with the one-way valve comprises a blood inlet pipe, the one-way valve, an air tube, an artificial heart body, a blood outlet pipe, a heart membrane, a rotary plate, a control cavity, movable plates, a movable body, springs and adjusting pipes. One end of the first adjusting pipe is communicated with the front-end blood inlet pipe, and the other end of the first adjusting pipe is communicated with a cavity between the first movable plate and the second movable plate; and one end of the second adjusting pipe is communicated with the blood outlet pipe, the other end of the second adjusting pipe is provided with three outlets, and the three outlets are respectively communicated with a cavity at the right side of the first movable plate, a cavity at the left side of the second movable plate and a cavity under the movable body. When the pressure of the front-end blood inlet pipe is high, the rotary plate rotates anticlockwise, and the amount of blood entering the blood cavity is reduced; when the pressure of the front-end blood inlet pipe is low, the rotary plate rotates clockwise, and the amount of blood entering the blood cavity is increased. The artificial heart with the one-way valve is reasonable in design and simple in structure, and is suitable for an artificial heart system for a patient who is sensitive to the blood pressure.
Description
technical field [0001] The invention relates to an artificial heart system in the technical field of medical instruments, in particular to an artificial heart with a blood pressure regulating mechanism and a one-way valve. 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 b...
