Abstract

The embodiment of the present invention discloses a magnetodynamic ventricular assist system, comprising: a magnetic induction device and a magnetic power device, the magnetic induction device is composed of a plurality of biocompatible magnetic induction sheets; the magnetic induction sheet is provided with a plurality of ventricular motion sensors and hemodynamic sensors; the magnetodynamic device is composed of a wearable coil, a power supply and a controller; the controller is used to adjust the wearable coil in real time according to the ventricular motion parameters and the hemodynamic parameters The internal current parameters generate a corresponding magnetic force; the magnetic induction sheet generates a driving force to assist the left ventricle and / or right ventricle to beat according to the magnetic force. The magnetodynamic ventricular assist system described in the present invention can achieve indirect contact with blood through an external magnetic induction device and a magnetodynamic device, avoiding the risks of wire winding, infection, bleeding, thrombosis, etc., and improving the end result. Survival and quality of life in patients with end-stage heart failure.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical care and health, and in particular to a magnetodynamic ventricular assist system. Background technique [0002] In recent years, with the rapid development of economy and society, people's living standards have been continuously improved, and cardiovascular system diseases have been increasing. Heart failure is a clinical manifestation of a series of pathophysiological changes caused by abnormal cardiac structure or function leading to impaired ventricular systolic or diastolic ability. syndrome. When heart failure occurs, the systolic ability of the heart to beat blood decreases, the compliance of the ventricles during diastole decreases, the active filling decreases significantly, the rate of change of systolic and diastolic volumes decreases, a large amount of blood remains in the heart, the pressure of the ventricles during diastole increases and the deformation of the cardiac cham...
