Electrode sheet of cardiac defibrillator

Abstract

The invention provides an electric shock / electrode sheet applied to electrocardiogram signal acquisition or a cardiac defibrillator. The electric shock / electrode sheet comprises a release sheet, an inner layer of foam, a conductive adhesive, a lead, a conductive layer and an outer layer of foam; and the electric shock / electrode sheet is characterized in that the conductive layer comprises a base layer which is made from a water-based graphene-silver-silver chloride composition. Major components in the conductive layer are such proportioned by weight that the ratio of graphene to silver to silver chloride is at (50-80%) to (14-35%) to (6-15%). The electrode not only can implement cardiac defibrillation, so as to meet patients with cardiac arrest, but also can conduct cardiac electrocardiogram signal monitoring, so as to meet special demands of doctors in monitoring heartbeats of the patients with the cardiac arrest. The electrode, which integrates functions of cardiac defibrillation andelectrocardiogram monitoring, not only can facilitate the doctors in consultation and examination so as to rescue patients' lives, but also can improve working efficiency of medical personnel, so that situations about patients' hearts can be observed in real time just through one screen.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an electrode sheet of 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 increase in the incidence of cardiovascular disease in my country, the incidence of sudden cardiac death has also increased significan...

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 HeartSaveAED-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
