Defibrillation system

Abstract

The invention discloses a defibrillation system. The defibrillation system includes a defibrillation device, an in-vitro monitoring module and a cloud end monitoring device, wherein the defibrillationdevice is an implanted defibrillation device; the defibrillation device is in communication with the in-vitro monitoring module; the cloud end monitoring device is in communication with the in-vitromonitoring module; the defibrillation device includes a control unit, a battery unit, a defibrillation circuit, a pacemaker circuit and a sensing circuit. The sensing circuit includes a sensing electrode, a high voltage protection circuit, a gain adjustable amplification circuit, a band pass filter circuit, a rectification circuit, a peak value detection circuit, a voltage sharing circuit, a comparator circuit and an output pulse in communicational connection in sequence. The rectification circuit is also connected with the comparator circuit. The defibrillation system provided by the invention is more stable and reliable in working.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more particularly to a cardiac defibrillation system. Background technique [0002] In 1899, Prevost and Batelli conducted a study of cardiac electrophysiology in dogs and found that low-energy shocks could induce ventricular fibrillation, while higher-energy shocks reversed ventricular fibrillation and restored a normal rhythm. From this, two physiologists first proposed the concept of electrical defibrillation. [0003] In 1933, Hooker, Kouwenhoven and others used 60Hz alternating current for the first time to successfully defibrillate experimental dogs. [0004] In 1947, German cardiac surgeon Beck successfully performed intrathoracic electrical defibrillation for a 14-year-old boy who suffered from ventricular fibrillation during thoracotomy, thus pioneering human electrical defibrillation therapy. [0005] In 1956, the German Zoll physician first used alternating current for ex...

AI Technical Summary

Problems solved by technology

Early defibrillators used alternating current, which caused great damage to the myocardium and limited the scope of use of the defibrillator
