Problems solved by technology

Once the heart function deteriorates, the self-beating ability decreases so that the ventricular contractility cannot overcome the aortic pressure formed by the axial flow pump auxiliary system, the ventricle stops bleeding, and the arterial blood pressure is completely expressed as non-pulsating pressure, and life is difficult to maintain
In addition, when the axial flow pump system runs at high speed and high flow rate, it is more destructive to the formed components of blood, which is not suitable for physiological needs, and it is difficult to maintain long-term use
[0008] None of the currently used cardiac assist devices have the ability to effectively work synchronously with the heartbeat; they do not have the ability to fully simulate the physiological pressure sequence in the ventricular chamber to assist the heart; they do not have the ability to be implanted into the ventricle to assist in repairing the shape of the heart and repairing the perforation of the interventricular septum; Not capable of correcting arrhythmias

Abstract

The invention relates to a heart impulse assisting device which comprises a heart ventricle capacity regulating device used for regulating the heart ventricle capacity, a synchronizer used for acquiring a heart ventricle contracting signal, and a control device used for receiving the heart ventricle contracting signal acquired by the synchronizer, wherein a sensor of the synchronizer is connectedto the heart; the synchronizer is internally provided with an automatic defibrillation device and a synchronization treatment device, a defibrillation electrode of the automatic defibrillation deviceis connected to the heart, and a pacing electrode of the synchronization treatment device is planted into the heart. The heart ventricle capacity regulating device of the heart impulse assisting device has small volume, thus the heart impulse assisting device can be planted inside the heart, can fully simulate the heart ventricle pressure capacity change rule and the heart synchronous impulse works, and can be used for assisting the heart impulse acting to treat the cardiac failure, form the heart ventricle and repair the perforation of ventricular septum.

Description

technical field [0001] The invention relates to a medical device, in particular to a heart beat assisting system. Background technique [0002] Heart failure is a syndrome caused by various heart diseases leading to insufficiency of the heart. The reason is that the decrease in myocardial contractility leads to cardiac stroke volume unable to meet the body's metabolic needs, and blood stasis in the heart increases the intracardiac pressure and expands the cardiac cavity during diastole, which further reduces myocardial contractility and aggravates cardiac insufficiency. As a result, the blood return of the systemic circulation and pulmonary circulation is blocked, and the congestion of the systemic and pulmonary circulation leads to dysfunction of the body's circulation and metabolic disorders of the body. When heart failure occurs, the systolic and blood-expelling capacity of the heart decreases, causing blood to remain in the heart, increasing the diastolic pressure of th...
