Electrical impedance tomography device for use with defibrillator, has protection circuit with safety device between electrode and signal input, where circuit uncouples tomography device from defibrillator, during high input current

摘要

The device has a protection circuit with a safety device (1) between an electrode (2) fixed on a patient and a signal input of the tomography device. The safety device includes two resistors that are in series connection with one another, and an amplifier stage arranged after the resistors. The protection circuit uncouples the tomography device from a defibrillator, during the occurrence of high input current.
