Energy supply system and method for fully-implantable-type blood pump

Abstract

The invention discloses an energy supply system and method for a fully-implantable-type blood pump. The system comprises an extracorporeal portion and an intracorporal portion. The extracorporeal portion comprises an external power source module, a driver, a power transmission coil, a voltage and current detection module, a controller, a wireless receiving module and a displaying module. The external power source module, the driver and the power transmission coil are sequentially connected. The voltage and current detection module detects the voltage and current of the power transmission coil and transmits the current and voltage to the controller. The controller is connected with the driver. The wireless receiving module is connected with the displaying module. The whole system is simple in structure and convenient to use. According to the energy supply method, energy transmission is achieved through magnetic resonance of the coil, the defects of a traditional blood pump energy supply system are effectively overcome, the infection caused when a wire penetrates through the skin is avoided, the system energy supply is more stable, the battery charging time is greatly shortened, the power transmission coil is directly sucked to the skin of the human body through a suction cup, and the power transmission coil does not need to be completely matched with an intracorporal power receiving coil in position.

Description

technical field [0001] The invention relates to an energy supply system and method for a fully implantable blood pump. Background technique [0002] The heart is an important organ of the human body, and heart disease is one of the major diseases that endanger human health. At present, there are more and more patients who need heart transplantation in the world, but heart donors are scarce all over the world, so many patients have lost their chances of survival. To solve this problem, the application of artificial heart (blood pump) was born. Artificial heart refers to a heart assist device that can partially or completely replace the function of the natural heart and maintain normal human blood circulation. It can help the failing heart to complete the circulation function, reduce the burden on the heart of patients with heart failure, and improve the clinical symptoms of patients. At the same time, reduce the patient's myocardial oxygen consumption, improve the myocardia...
