Description

electrotremor device

Technical field

The invention belongs to the field of animal experiments, and specifically relates to an electric tremor-inducing device.

Background technique

In the process of animal experiments in clinical medicine, it is often necessary to cause experimental animal subjects to produce abnormal heart rhythms to simulate diseased heart rhythm conditions and verify the safety and effectiveness of medical devices or drugs. The most common one is to cause experimental animals to produce ventricular fibrillation rhythm; for example, when conducting animal experiments on defibrillation equipment such as defibrillators and AEDs, it is necessary to make the animals produce a defibrillable heart rhythm (usually a ventricular fibrillation rhythm). Defibrillators, AEDs and other defibrillation equipment only have experimental treatment subjects and can trigger the equipment to perform defibrillation operations. Therefore, in this type of animal experiment, inducing fibrillation in experimental animals, that is, inducing ventricular fibrillation, is a key operation in preparing for animal experiments.

There are many ways to induce tremor, such as drug-induced tremor, asphyxiation-induced tremor, and electrical tremor-induced tremor. Among them, drug-induced tremor and asphyxiation-induced tremor can 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 myocardium of animals after defibrillation treatment. The test results will be used as an important factor in analyzing the safety of defibrillation equipment, and the effects of drug-induced fibrillation and asphyxia-induced fibrillation on myocardial tissue will interfere with this analysis.

Electrical fibrillation is an excellent method to induce ventricular fibrillation in animals, and its impact on animals is relatively small. However, the current electrotremor induction methods used in laboratories are usually extensive and lack precise control, and the induction of tremor is prone to failure. It requires repeated attempts to successfully induce tremor, which depends on the proficiency of the experimental operator.

After the time t21 is over, the first switch K1 is closed and the second switch K2 is opened. Then the processor CPU immediately monitors and identifies whether the ECG waveform is a ventricular fibrillation rhythm waveform. If it is not a ventricular fibrillation rhythm waveform, that is Repeat the waiting time t2 and subsequent processes until the processor CPU recognizes the ventricular fibrillation rhythm waveform. At this time, the interface displays the ventricular fibrillation rhythm waveform and a voice prompts that the fibrillation induction is successful, and records the fibrillation induction parameter values in the above process.

After completing the placement of the above tremor-inducing electrodes, if the automatic mode is selected, wait for a period of time t1. The preferred value of time t1 is 15 seconds. After the waiting time t1 is over, the voice prompt and interface display: Tremor can be induced and wait for 10 seconds. Please do not interfere after starting the tremor induction; when the 10-second countdown is over, the first switch K1 is automatically turned off and the second switch K2 is closed, and the tremor induction output is maintained. After the time t11, the preferred time t11 is 3 seconds. After t11 ends, close the first switch K1 and open the second switch K2. Then the processor CPU immediately monitors and identifies whether the ECG waveform is a ventricular fibrillation rhythm waveform. If it is not a ventricular fibrillation rhythm waveform, the waiting time t1 and subsequent processes are repeated. ; Until the processor CPU recognizes the ventricular fibrillation rhythm waveform, at this time the interface displays the ventricular fibrillation rhythm waveform and a voice prompts that the fibrillation induction is successful, and records the fibrillation induction parameter values in the above process.

Parameter recording content includes: 1. The ECG waveform monitored by the ECG monitoring module throughout the entire process; 2. The impedance value between the fibrillation-inducing electrodes; 3. The fibrillation-inducing mode: constant voltage mode/constant current mode, automatic mode/semi-automatic mode ; 4. The number of tremor inductions; 5. The tremor voltage value of each tremor induction (in constant voltage mode, it is the V value, in the constant current mode, it is the product of I and the impedance value) and the current value (in the constant voltage mode, it is V The ratio to the impedance value is the I value in constant current mode); 6. The heart rate is the tremor-inducing square wave frequency value of constant voltage/constant current.

In this embodiment, in both the automatic mode and the semi-automatic mode, the bidirectional square wave of the tremor-inducing output set in the constant current mode or the constant voltage mode can be output.
