Abstract

The invention discloses an implantable left ventricular assisting system which comprises an in-vivo module and an in-vitro module. No transmission lines exist between the in-vivo module and the in-vitro module. The in-vitro module comprises a strong current power supply unit, a power supply end power converting unit, a resonant transformation unit, a primary side coil of a loosely coupled transformer, a power supply end weak current power supply unit, a power supply end controller, a switch tube drive unit, an optical coupler isolating unit, a current sampling unit, a power supply end signal conditioning unit, a protecting unit, a battery state display module and a demodulator for receiving battery state information. The in-vivo module comprises an auxiliary side coil of the loosely coupled transformer, a receiving end resonant transformation unit, a receiving end power conversion unit, a receiving end controller, a battery charging management module, a battery, a modulator and a blood pump. The implantable left ventricular assisting system is simple and compact in structure, small in size and lightweight, and subcutaneous wire holes of a patient can be avoided.

Description

technical field [0001] The invention belongs to a medical device, in particular to an implantable left ventricular assist system. Background technique [0002] Left Ventricular Assist Devices System (LVADS for short) is mainly used to treat patients with congestive heart failure such as coronary atherosclerotic heart disease, hypertensive heart disease, and cardiomyopathy. LVADS is a device that draws blood from the patient's left ventricle and pumps it into the aorta under pressure. The device consists of three parts: pump main body, control system and power supply system. Its purpose is to partially or completely replace the function of the heart to maintain blood circulation; one is to reduce the load on the heart, increase the coronary flow, and restore the function of the failed heart in a state of low metabolism and unloading; the other is to ensure the vital organs of the whole body. Perfusion, prevention and treatment of multiple organ failure, to ensure the effect...
