Abstract

The invention discloses a magnetic dive axial-flow heart assistant pump, composed of stator, rotor, and DC voltage-stabilized power supply. The stator comprises stator winding and stator casing and the rotor composed of tube high-energy level magnet and propelling equipment. The propelling equipment integrated composed of internal sleeve, central shaft and two impeller blades to develop a spiral sealed blood propelling channel; the rotor is placed in the subulate shaft sleeve of stator cantilever. The stator winding generates magnetic field to drive the rotor to put the blades in motion, makes the blood one-way flow and assists or completely replaces the heart to pump blood. The stator winding is connected with the power supply.

Description

Technical field

[0001] The invention relates to a heart assist pump. Background technique

[0002] During nearly half a century of research on cardiac assist devices, their materials, structures, manufacturing processes, functions, and service life have been continuously improved and developed. Different driving methods such as pneumatic, electric, and electro-hydraulic have appeared. The blood flow is also closer to the physiological heart. Heart assist devices are an important means of maintaining life for critically ill patients. It is divided into three ways: final replacement, waiting for transplantation, reducing heart load, and promoting functional recovery.

[0003] With the continuous development of medical science, more and more patients are suffering from acute heart failure, unable to leave the cardiopulmonary bypass machine after heart surgery, and waiting for heart transplantation. They are in urgent need of cardiac assistance for short-term transition or long-term ...
