Abstract: An apparatus for central electroanalgesia comprises units for rhythmic action, which are connected in series with units for changing the shape of current pulses and preamplification units electrically coupled to a regulator of the amplitude of current pulses, a means for selecting a mode of action, a means for programmed limitation of the current average value, and a means for amplifying the output signal, which is connected, via a means for measuring the current average value, to electrodes secured on the patient's neck below the mastoid processes and on his forehead. The output signal amplifying means is connected to a compensation current limiting unit couple to a constant component compensating unit joined to a compensation current regulator.

Abstract: A device for pulse current action on the central nervous system includes a current pulse preamplification unit and a unit for adjusting a value of an additional constant component. The current pulse preamplification unit is coupled via a switch to the current pulse duration adjusting unit of the device to produce the second level of the first stage of general electroanesthesia, or to the intermittent analgesia unit of the device to make it possible to anesthetize growing pain. The unit for adjusting the additional constant component value is connected to the power unit of the device. This permits the reduction of the impedance at the points where the electrodes are attached to the forehead and neck areas.
