Description

Method and device for electrical induction of fibrillation

technical field

The invention belongs to the field of animal experiments, and in particular relates to an electrical inducement method and device.

Background technique

In the process of animal experiments in medical clinics, it is often necessary to make experimental animal subjects generate abnormal heart rhythms to simulate diseased heart rhythm conditions to verify the safety and effectiveness of medical devices or drugs. Among them, the most common is to make experimental animals produce ventricular fibrillation rhythm; for example, when animal experiments are performed on defibrillator, AED and other defibrillation equipment, animals must produce defibrillable rhythm (usually ventricular fibrillation rhythm), defibrillation Only when defibrillation equipment such as instrument and AED have experimental treatment objects can the equipment be triggered to perform defibrillation operations. Therefore, in this kind of animal experiment, to induce fibrillation in experimental animals, that is, to induce ventricular fibrillation, is the key operation for animal experiment preparation.

There are many ways to induce tremors, for example, drug-induced tremors, asphyxia-induced tremors, and electrical tremors. Among them, drug-induced fibrillation and suffocation-induced fibrillation will cause damage to the myocardium and other tissues of animals, forming interference factors in the animal experiment process; for example, in the animal experiment process of defibrillation equipment, it is necessary to slice the animal myocardium after defibrillation treatment. The test results will be an important factor in the analysis of the safety of defibrillation equipment, and the effects of drug-induced defibrillation and asphyxia-induced defibrillation on myocardial tissue may interfere with this analysis.
