->f1.c is used in complex electrical painkillers to strengthen the action (shi, cheapness?) without producing overstimulation. 13 are respectively applied to the patient's forehead and armpit area under mastoid treatment. A sawtooth wave voltage pulse train is generated at the output terminal 19 of the regulator 2 (i) connected to the regulator 2 (i, which allows the pulse repetition rate to be changed smoothly over one cycle. The repetition frequency of the pulses is equal to the repetition frequency of the square wave nosolus applied to the input terminal of the unit 20. The unit 2 independently and smoothly adjusts the repetition frequency and duration of the pulses. At the same time, a sawtooth voltage pulse train is applied to the input terminal of the unit 20. This unit 21 is used for changing the period-duration ratio of the norm ξ and forming rectangular pulses from the sawtooth voltage in the unit 21. This is an amplifier for preamplifying the sawtooth voltage to the required level.The input terminal of the unit 210 is connected to the unit Δ), and the operation of this device is controlled by the switch Δ). A ratio regulator 29 allows operation in varying period-duration ratio conditions.Unit 2 (FIG. 3) has one input terminal for receiving a sawtooth voltage norm ξ; Alternatively, another input terminal is provided which receives a constant voltage from the regulator 29 via the switch 5. The amplitude of the constant voltage is determined by the unit 30 or by the regulator 29. The amplitude of the sawtooth voltage is determined by the unit 21. The output of the unit 21 is therefore a rectangular pulse train with a duration that is the difference between the amplitude of the sawtooth voltage and the amplitude of the constant voltage.The input of the unit 21 is When the constant tortoise pressure changes at a terminal, a square wave pulse train is generated at the output terminal of the unit 21. The duration of the square pulse can be adjusted. This means adjusting the period-duration ratio. The ability to adjust the period-duration ratio allows simultaneous adjustment of the length and repetition frequency of the current pulses in the remote electrical pain relief unit 30 (FIG. 1). This prevents excessive stimulation and discomfort from being given to the lower part of the electrode when the action is strengthened. Similarly, the force can be increased by the Tli flow parameter ξ, stabilized by the period-duration ratio adjusting unit 29. In the variable direction/duration ratio condition, a pulse train is applied from unit 2 to the input terminal of unit 3. The ξ pulse train is equal to 2, resulting in a square wave pulse train with a constant period-duration ratio of °C. The output signal of unit 3 is then applied to the input terminal of unit 4. In this unit 4 the duration of these pulses can be varied smoothly. Further, the signal is applied from the unit 4 to the input terminal of the unit 70 via the pulse waveform changing unit 5 and the function switch 8. When the duration of the output pulse of unit 4 is longer than the duration of the input pulse of unit 4, comparator 31 generates a signal and provides the signal to controller 32. A square wave pulse train is applied from the output terminal of unit 3 to the other input terminal of controller 32, thereby resetting unit 32. Therefore, unit 32 provides a square wave pulse train to indicator A. From the output of unit 4 a signal of a specific duration is applied to the input of unit 5. In this unit 5 the waveforms of these pulses are changed. The output signal of unit 5 is transferred to unit 1 via function switch 8 in position 1.

By adjusting the distance, the average value of the current can be adjusted smoothly over a distance. The strength of the pulse action can thereby be varied. Another output terminal of the remote electric pain relief unit 30 is connected to the preamplifier 7 via the switch B, and another output terminal of the remote electric pain relief unit (equipment) is connected to the additional DC component adjustment via the switch 24. 17. This allows remote control of the ξ norm amplitude and the level of the additional DC component. Switches 22, 23, and 24 can control the remote pain relief process by applying the unit, and if required, the regulator 2 can be controlled.
6, 27, 28 allow control of selected parameters of the pulse action. When the function switch is placed in position ■, the output terminal of unit 21 is connected to the input terminal of unit 70. this is,
This means that the period-duration ratio can be changed during operation of the device. The period-duration ratio is adjusted by a regulator 4, which is connected to the unit 2J via a switch B, or by a remote analgesic unit 30, whose output terminal is connected to a switch δ.
