Description

Artificial intelligent heart magnetic suspension host pump and application method thereof Technical Field The invention relates to the technical field of medical appliances, in particular to an artificial intelligent heart magnetic suspension host pump and a use method thereof. Background Heart failure refers to heart failure caused by dysfunction of systolic function and/or diastolic function of heart, venous blood quantity cannot be fully discharged out of heart, venous system blood is accumulated, arterial system blood is not filled enough, and heart circulatory disturbance syndrome is caused, an artificial heart for assisting treatment of heart failure patients in the prior art can be divided into a blood pump and a power pump, wherein the blood pump takes a motor or magnetic suspension as power to drive an impeller in the pump to rotate, and blood pumped from a ventricle of heart failure is pumped into a main artery through an artificial blood vessel; the power pump is used for completely and synchronously inflating and deflating the functional units wrapped around the heart and the cardiac cycle by a host machine in vitro or in vivo to compensate the power of contraction and relaxation for the failed heart, so as to achieve the aim of improving or completely recovering the heart function. The prior art has the defects that the blood pump needs to be in direct contact with blood, complications and secondary damage are easy to cause, the effect of improving heart failure and recovering heart functions is limited at the same time, the power source of the host of the overseas existing power pump (a myocardial pump of the university of Harvard and a pericardium pump of the university of Munich) has loud sound during working and running, the host is large in volume and inconvenient to fully implant in a body, and is inconvenient to carry, and meanwhile, the existing power pump is used for an air pump and an air pump at the same time, so that the effects of high-pressure air inflation and low-pressure air suction are formed, the number of pumps is large, the structural volume is increased, and the shape of the heart is deformed when the high pressure and the low pressure are unbalanced, so that the structural shape of the heart is influenced. Disclosure of Invention The invention overcomes the defects of the prior art, provides an artificial intelligent heart magnetic suspension host pump and a use method thereof, and aims to solve the problems that a power pump in the prior art is large in mechanical structure and difficult to install in a body, and optimize the power pump structure so that the power pump can be matched with an intelligent heart for use.
