A shock/electrode pad for ECG signal acquisition or cardiac defibrillator

Abstract

The invention provides an electric shock / electrode slice for ectrocardiosignal acquisition or a heart defibrillator. The electric shock / electrode slice comprises a release sheet, internal-layer foam, a conductive resin, a lead wire, a conductive layer and external-layer foam, and is characterized in that the conductive layer comprises a base layer prepared by use of a water-base graphene-silver-silver chloride compound. The weight ratio of major components in the conductive layer is: graphene: silver: silver chloride=(50%-80%):(14%-35%):(6% -15%). According to the invention, the electric shock / electrode slice, as a heart electric defibrillation electrode, satisfies the application requirement of a cardiac arrest patient, and at the same time, as an electrode for monitoring heart electrocardiogram signals, can also satisfy the special need of a doctor for monitoring the heartbeat of the cardiac arrest patient. A heart electric defibrillation function and an electrocardiogram monitoring function are combined into one, diagnosis examination of the doctor is facilitated, the life of the patient is rescued, the work efficiency of medical care personnel is also improved, and the heart condition of the patient can be checked in real time simply through one screen.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to the improvement of an electric shock sheet for cardiac defibrillation, in particular to an electric shock / electrode sheet for collecting electrocardiographic signals or a cardiac defibrillator. Background technique [0002] Sudden cardiac death refers to natural death from cardiac causes that occurs within 1 hour after the onset of acute symptoms and is characterized by sudden loss of consciousness. Sudden death was defined by the International Society of Cardiology, the American Heart Association in 1979, and the World Health Organization in 1970 as: accidental death that occurs immediately or within 24 hours after the onset of acute symptoms. At present, most scholars tend to limit the time of sudden death within 1 hour of onset. It has three characteristics: ① sudden death; ② unexpected death; ③ natural death or non-violent death. [0003] In recent years, with the inc...

Problems solved by technology

[0009] It is technically difficult to display the electrocardiogram image on the AED cardiac defibrillator. In this way, the doctor needs to add an electrocardiogram machine for monitoring. If the electrocardiogram machine feedback is slow or there is a problem, the result may cause the patient to not receive timely treatment. At present, these two devices are independent and have nothing to do with each other, and misdiagnosis accidents are also very easy to occur.

[0010] For the portable AED cardiac defibrillator, the two functions cannot be combined. The main problem is the collection of electric shock film and the processing of the electrocardiograph by the machine software.

[0011] Although from 2011 to 2012, the HeartSave AED-M Enhanced Type of AED automatic defibrillator in Germany has superimposed the two functions on its machine, but the whole machine and electric shock pads are expensive and not easy to popularize
