A cardiac interventional left ventricular electromagnetic assisting device

Abstract

The invention discloses a cardiac interventional left ventricular electromagnetic assisting device, which mainly includes: an external control device and a blood pump, the external control device and the blood pump are separated through the skin layer, and the external control device and the blood pump are connected through an electromagnetic field The in vitro control device is a box with a rectangular cross section, and the outer front of the box is sequentially provided with a power adjustment knob, a current adjustment knob, a power switch, an electromagnetic auxiliary switch, a liquid crystal display, a charging holes; the present invention uses electromagnetic induction control technology, does not need to drill wire holes under the patient's skin, prevents infection, is easy to operate, and can be controlled and adjusted continuously for a long time; adopts a new type of magnetic levitation axial flow blood pump, which has high control precision and makes the artificial heart The gravity balance of the magnetic field can maintain the balance of the magnetic field force on the artificial heart and improve the life of the artificial heart, which can be widely used clinically.

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...

AI Technical Summary

Problems solved by technology

[0005] However, the control of the current magnetic levitation blood pump is completed by connecting the implantable wire to the external control device, which requires opening holes in the body, which is easy to cause infection, and the control process is completed by simple current control, and the accuracy of flow rate control is low.
