An apparatus for current pulses action upon the central nervous system, in which current pulses are supplied from a unit for rhythmic current pulse action upon the central nervous system of a patient via a unit for regulating the duration of current pulses or via an intermittent analgesia unit, a unit for adjusting the amplitude of current pulses and a unit for indicating the mean current intensity value to the patient through electrodes, a cathode attached in the patient's forehead area and an anode attached in the patient's neck area below the mastoids, the above mentioned pulses being stopped by means of a patient protection unit, when a specific amplitude of current pulses is attained. The apparatus provides for regulation of the repetition frequency of current pulses, their amplitude and the level of the additional direct component, depending on the intensity of pain in the patient. For this purpose, an autoelectroanalgesia level remote control unit is provided, which is coupled by three outputs thereof respectively to the intermittent analgesia unit, to the unit for adjusting the amplitude of current pulses, which is additionally connected to a power unit, and to the power unit. All this enables the patient, depending on the intensity of pain, to select an individual level of anesthesia. In this case, during acute pain, the intensity of pulse action is increased by simultaneous step-up of the repetition frequency of pulses, their amplitude and the level of the additional direct component. |
