Abstract

The invention discloses a cardiac intervention type left ventricular electromagnetic assisting device which mainly comprises an in-vitro control device and a blood pump. The in-vitro control device isisolated from the blood pump by a skin layer and is connected with the blood pump by electromagnetic fields; the in-vitro control device is a box with a rectangular cross section, a power regulationknob, a current regulation knob, a power switch, an electromagnetic auxiliary switch and a liquid crystal display are sequentially arranged on the front surface of the outer side of the box from leftto right, and a charge hole is formed in the front surface of the outer side of the box. The cardiac intervention type left ventricular electromagnetic assisting device has the advantages that electromagnetic induction type control technologies are utilized, accordingly, wire holes do not need to be drilled under the skin of patients, infection can be prevented, and the cardiac intervention type left ventricular electromagnetic assisting device is easy to operate and can be continuously controlled and regulated for a long term; the cardiac intervention type left ventricular electromagnetic assisting device with the novel magnetic suspension axial flow type blood pump is high in control precision, magnetic field gravitation on an artificial heart can be balanced, the balance of magnetic field force on the artificial heart can be kept, the service life of the artificial heart can be prolonged, and the cardiac intervention type left ventricular electromagnetic assisting device can be clinically widely applied.

Description

technical field [0001] The invention belongs to the technical field of cardiac assisting medical devices, and in particular relates to a cardiac interventional left ventricular electromagnetic assisting device. Background technique [0002] Artificial blood pumps are small pumps with variable speed and variable capacity used to completely replace the work of the heart. According to the working principle of blood pumps, the types of blood pumps are divided into volumetric type and vane type; according to different auxiliary methods, they are divided into total artificial heart, Ventricular assist device; according to different driving methods, it is divided into pneumatic, electric and magnetic drive; according to the implantation position, it is divided into extracorporeal type and implantable type. [0003] Compared with volumetric blood pumps, vane blood pumps can overcome the problem of large size and inconvenient implantation, mainly including centrifugal pumps and axial...
