Problems solved by technology

[0005] The technical problem solved by the present invention is to overcome the disadvantage that the blood pump of the existing magnetically driven ventricular assist device hinders the return of blood to the heart and easily leads to myocardial infarction, and provides an artificial heart with extracardiac auxiliary circulation that can ensure the return of blood

Embodiment Construction

[0031] figure 1 It is a schematic diagram of the structure of the extracardiac assisted circulation type artificial heart used in the human body according to the first embodiment of the present invention, figure 2 for figure 1 The driving schematic diagram of the extracardiac assisted circulation artificial heart in . Such as figure 1 and figure 2 As shown, the extracardiac assisted circulation artificial heart of the present invention includes a driver 11 located outside the human body, an artificial blood vessel 13 that can be connected between the ventricle 321 and the arterial vessel 33 and communicates with the ventricle 321 and the arterial vessel 33, and an installation The blood pump 12 in the artificial blood vessel 13. The artificial blood vessel 13 is made of biocompatible materials, and can be connected with the ventricle 321 and the arterial vessel 33 through surgery. The blood pump 12 is an axial flow pump with a pump casing (not shown in the figure) and a...

Abstract

The invention discloses an exocardial assisted-circulation artificial heart. The exocardial assisted-circulation artificial heart comprises a driver outside a body, an artificial blood vessel connected between a heart chamber and an artery blood vessel and communicated with the heart chamber and the artery blood vessel, and a blood pump installed into the artificial blood vessel. An impeller of the blood pump is provided with a pump magnet as a permanent magnet. The driver can produce a magnetic field alternating an N pole and S pole in the direction of the pump magnet in order to drive the pump magnet to rotate the impeller of the blood pump. The technical scheme provided by the invention helps to solve the problem that a conventional blood pump for magnetically driving an auxiliary device of the heart chamber may prevent blood from flowing back to the heart and therefore the possibility of myocardial infarction is avoided; and the auxiliary recirculation-type artificial heart which may ensure blood backflow is provided.

Description

technical field [0001] The invention relates to the field of artificial heart. Specifically, it is an artificial heart of an extracardiac auxiliary circulation type. Background technique [0002] Heart disease is a major killer of modern people's health. Not only the heart of the elderly is prone to problems due to aging, but more and more young people will also suffer from heart disease in a fast-paced, high-stress life. Among them, heart failure or heart weakness caused by other heart diseases can be treated by implanting artificial pumps. Artificial pumps are usually implanted in the aorta or pulmonary artery to provide pressure to the blood in the aorta or pulmonary artery so that blood flows to the lungs or the whole body. Because there is an artificial pump to provide pressure for the blood, the ventricle can reduce the amount of compression or not compress, which greatly reduces the burden on the heart. After a period of decompression, the systolic function of the ...
