Left-ventricle assisting device and application method

Abstract

The invention discloses a left-ventricle assisting device and an application method. The left-ventricle assisting device comprises a left-ventricle skeleton and air sacs, wherein the left-ventricle skeleton comprises a primary skeleton and a plurality of secondary skeletons; the multiple air sacs are arranged on the outer side face of the primary skeleton in the axial direction of the primary skeleton, and are arranged between the primary skeleton and the secondary skeletons; the air sacs fit an inner membrane of the left ventricle; the primary skeleton is communicated to the secondary skeletons; the secondary skeletons are communicated to the air sacs; a sensor is arranged at the end, fitting the inner membrane of the left ventricle, of each secondary skeleton; a gas power system comprises a flexible pipe, a pneumatic device and an electric circuit, one end of the flexible pipe is arranged in the primary skeleton, and the other end of the flexible pipe is arranged at an outlet of thepneumatic device; the pneumatic device comprises a shell, a micro motor, a valve and a pushing rod. According to the left-ventricle assisting device and the application method, the ventricular wall ofthe left ventricle is protected and prevented from being fractured, inverse motion of ventricular aneurysm of the left ventricle is prevented, and the device assists the left ventricle in achieving accurate pace-making, and meanwhile assists blood in stroking out of the left ventricle.

Description

technical field [0001] The invention relates to the technical field of cardiovascular medical devices, in particular to the technical field of a left ventricular assist device. Background technique [0002] At present, most of the left ventricular assist devices used in clinic are to introduce the blood flow of the left atrium or left ventricle into the auxiliary pump body, and then drive the blood flow into the aorta through the pump body, completely replacing the left heart pumping function. This requires not only complex surgery, but also complex and expensive instruments. In clinical work, the patients who most need left ventricular assist device treatment are mostly patients with cardiac insufficiency after severe large-area myocardial infarction; the existing left ventricular assist device not only requires general anesthesia, but also the operation cost is expensive; greater pain. SUMMARY OF THE INVENTION [0003] In view of the above deficiencies, the purpose of ...
