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. The current pulse preamplification unit and the unit for adjusting the additional constant component value are connected to the power unit and the patient protection unit of the device to limit the general electroanesthesia level in accordance with a prescribed anesthesia and treatment program, while performing current pulse action of the patient'"'"'s central nervous system. The outputs of the current pulse preamplification unit and the unit for adjusting the additional constant component value are connected to the inputs of the current pulse amplitude adjusting unit of the device, which, in turn, is connected to the current pulse amplitude indicator of the device.
