Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of artificial heart auxiliary device.
Background technique
Heart failure (heart failure) abbreviation heart failure, refers to the contractile function and (or) diastolic function due to heart
Obstacle occurs, heart cannot be sufficiently discharged in venous return, lead to venous system sludging, arterial system hemoperfusion
Deficiency shows as pulmonary venous pleonaemia, vena cave extravasated blood so as to cause cardiac cycle obstacle syndrome in such obstacle disease cluster.The heart
Force failure is not an independent disease, but the terminal stage of heart disease development.Wherein most of heart failure
All it is to be started with left heart failure, that is, first appears as pulmonary circulatory stasis.Heart failure medications treatment two annual survival rates about 80%, 5 years
Survival rate only 50% or so.The treatment of heart failure must be sought to break through, and could save a large amount of frequency dead person group.
It is effective especially to merge cardiogenic shock person to Low cardiac output heart failure for intra-aortic balloon counterpulsation at present, but due to setting
It is standby heavy, it cannot carry, be not suitable for, be inconvenient to be used for a long time.External artificial heart research all concentrates on imitating heart knot mostly
On structure, and to replace and cut off heart of patient, and due to energy supply deficiency, although also there is artificial heart applying clinical,
Patient's mortality risk is big, and the service life is very short, is not that patient receives, and promotes finally because service life is short, complication is more
It is difficult.Since donor lacks, operation wound is big for heart transplant, and at high cost, immunological rejection is high, is often difficult to be widely implemented.
Summary of the invention
To solve the above-mentioned problems, it the task of the present invention is a kind of artificial heart auxiliary device is provided, can actively promote
Heart contraction or diastole make heart restore normal blood-pumping function, improve symptoms of heart failure, and using when do not need excision heart,
