Conductive gel tablet for defibrillator

Abstract

The invention provides a conductive gel tablet for a defibrillator. Conductive particles are dispersed in aqueous solution of crylic acid according to a scale for preparing the water-absorbing conductive gel tablet, and the conductive gel tablet used for the defibrillator is prepared after aggregating polyaniline. An interactive network structure is formed due to interconnection between the conductive particle in a PAA network and a polyaniline chain, so that a conductive channel is formed, and the conductivity of the prepared conductive gel tablet is 9.3*10<-3>S.cm<-1>.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a conductive gel sheet for a defibrillator. Background technique [0002] Ventricular fibrillation is the most common fatal arrhythmia causing cardiac arrest. About 80% of patients with cardiac arrest are caused by ventricular fibrillation; the most effective treatment for ventricular fibrillation is electrical defibrillation; the probability of successful defibrillation varies with The lapse of time decreases, or every minute defibrillation is delayed, the success rate will drop by 7% to 10%; ventricular fibrillation may turn into cardiac arrest within a few minutes. Therefore, early and rapid defibrillation is the most critical link in the chain of survival. [0003] The method of passing a strong pulse current through the heart to eliminate arrhythmia and restore it to sinus rhythm is called electric shock defibrillation or electric cardioversion. Both pacing and defibrillatio...

Problems solved by technology

[0004] Since there is a thin layer of sebum on the surface of the human skin, which is a poor conductor of bioelectricity, it is necessary to apply a conductive medium to eliminate the sebum, so that the electrode block is in close contact with the body surface to effectively conduct current. The defibrillation electrode plate uses a conductive medium Generally, it is conductive paste or saline gauze, but this method is likely to generate an arc between the skin and the electrode plate, burn the skin, and bring great pain to the patient

In addition, due to the uneven application of the conductive paste, there is a difference in charge density on the contact surface of the electrode plate, which reduces the working efficiency of the electrode plate, and after the coated conductive paste or salt water contacts the electrode plate, it is easy to cause the surface of the electrode plate to Corrosion reduces the service life of equipment
