Metrax Primedic M240 DM1 defibrillator Voltage Converter 630.9200.00.07

►Quick Detail:

The voltage converter converts DC low voltage into pulse high voltage, and then charges the energy storage capacitor C after high voltage rectification, so that the capacitor obtains a certain amount of energy storage. During defibrillation treatment, the high-voltage relay K is controlled to operate, so that the charging circuit is cut off, and the energy storage capacitor C, the inductor L and the human body (load) are connected in series to form an RLC (R is the resistance of the human body, the resistance of the wire itself, the human body and The sum of the three contact resistances of the electrodes) the series resonance attenuated oscillation circuit is the damped oscillation discharge circuit, the current waveform passing through the human heart.

When the pulse power supply discharges the driving coil, a large pulse current of more than ten kiloamps or even tens of kiloamps will be generated. Commonly used large current measurement methods include shunt method, optical method, Hall effect method and Rogowski coil method. In recent years, researchers have explored new pulsed high current testing technologies such as electro-optical methods and magneto-optical methods.

The bidirectional peak current of this RLC discharge has a better defibrillation effect and causes less damage to human tissue. The discharge time is generally 4~10ms. An open-circuit iron core coil is used to prevent the output waveform from changing due to a drop in the inductance value due to saturation of the iron core caused by large current during discharge. In addition, there is high voltage in defibrillation, which poses a risk of accidental electric shock to the operator and the patient. Therefore, incorrect operations must be prevented and various protective circuits must be adopted.

► Things to note when using voltage converters:

1. Before use, it is necessary to confirm that the voltage converter has sufficient capacity to ensure that the converter can drive the defibrillator normally, thus extending the service life of the converter.
2. It is best not to run it for a long time during daily use, and the power supply of the converter needs to be disconnected when not in use.
