25 are connected to the unit 14 by remote electroanalgesia.

In addition, the device has an indicator unit 21, which is connected by its input to a control unit 22, which is connected to the outputs of the unit 3 and the signal comparison unit 23 by its inputs. Signals from the input and output of block 4 arrive at the inputs of block 23. These blocks provide an indication of a possible breakdown of oscillations in the modes that exceed the pulse duration over the pause between pulses. The rhythmic stimulation unit is connected with the input of the unit 24, prior to sawing voltage amplification, the unit 25 for changing the duty cycle and generating rectangular pulses from the sawtooth one is connected to the switch 6 of the operation mode and

5 through the switch 26 with the block 11 - the pulse duty ratio controller.

The device works as follows. After determining the need to increase the depth and stabilize the pulse effect during anesthesia during labor, in the postoperative period, during combined electroanesthesia, electrodes are fixed in the area of the forehead and neck under the mastoid processes (cathode and anode).

At the output of the rhythmic block 1, a sequence of square impulses is formed. At the same time, a smooth f) pulse frequency is conducted by the doctor with the help of the controller 15, which is connected to the block 1 through the switch 18.

In addition, at the second output of block 1, a sequence of sawtooth voltage pulses is formed, the frequency of which is equal to the frequency of the sequence of rectangular pulses fed to the input of block 2, which provides independent and smooth adjustment of the frequency and duration of pulses. At the same time, a sequence of sawtooth voltage pulses is fed to the input of block 24, which is a preamplifier of a sawtooth voltage amplitude to a level that is necessary to change the duty cycle of forming a square of pulses from sawtooth in block 25, which is connected by its input to the block 24 and a block 26 by a switch that allows operation in an adjustable duty cycle or a remote control or by using a controller 27 on the front panel of the device. The block 25 has an input to which the saw-tooth voltage is supplied, and a second input to which a constant voltage is supplied through block 26 from blocks 14 or 27. The magnitude of the constant voltage amplitude is determined by blocks 14 or 27, and Block 25 compares the amplitude of the sawtooth voltage with the amplitude of the constant voltage, which is removed from block 26.

At the output of block 25, a sequence of rectangular pulses appears, the duration of which is determined by the excess of the amplitude of the sawtooth pulses under the value of the constant voltage, which is removed from block 2.6.

A change in the DC voltage at the input of the unit 25 leads to the appearance at its output of a sequence of rectangular pulses with an adjustable duration — the adjustment of the duty cycle of the pulses.

As a result of the adjustment of the duty cycle, it is possible to simultaneously change on the remote control the duration of rectangular pulses in combination with the adjustment of the level of the additional constant component, amplitude, frequency. When using a regulated duty cycle operation solution, the output signal frequency does not malfunction, since the pulse duration cannot become longer than the pulse following period, which is provided by the unit 25 of the present device.

A similar mode of operation to increase the depth of exposure, provided that the current parameters are stabilized, can be used without transferring to the remote control by adjusting the pulse duty ratio by the unit 27.

In the variable-duty cycle mode, a sequence of pulses from block 2 is fed to the input of block 3, which serves to form a sequence of rectangular pulses with a constant bore ratio of two.

Then the pulse signal from the output of block 3 is transmitted to the input of block 4, where the pulse width is continuously regulated, and the operating mode switch 6.

If the pulse duration at the output of block 4 is longer than the pulse duration at the output of block 4, then the output of the comparator block 23 will be a signal that is fed to the control block 22. A sequence of rectangular pulses from the output of block 3 is applied to the other output of block 22, which brings the block 22 to the initial state.

As a result, at the output of block 22, after a signal from block 23 about increasing the pulse by a pause pulse, a sequence of pulses is formed with a tracking frequency equal to the pulse following frequency at the output of block 3, which turns on the indicator block 21, which indicates the beginning of an excess for the pulse the pause duration, which can lead to disruption of oscillations or an abrupt change in the frequency at the output of the device.

Formed after checking the indicator for the duration of the pulse signal from the output of block 4 is fed to the input of block 5, where there is a change in the shape of the pulses. After that, the pulse signal from the output of block 5 through switch 6 in position I is fed to the input of unit 7. At the same time, the amplitude adjustment of the pulses is carried out by the doctor with the aid of the regulator 16, which through the switch 19 can be connected to the pre-amplification block 7. The amplified pulse signal from the output of block 7 is fed to the first input of the adder 8 of a pulse action and an additional constant component, and from the output of block 12 a signal of an additional constant component is received. The total pulse signal from the output of block 8, containing the constant component, through the block 9 of measurement of the average current value goes to the patient. Unit 10 at the same time continuously monitors the amplitude of the current. The block 13, included in the feedback circuit, automatically limits the average current value in the patient circuit. The inputs of block 13 are connected to the output of block 8 and block 11, and two outputs to the inputs of blocks 7 and 12, which ensures the protection of the patient without stopping the operation of the device. The presetting of the additional constant component value is carried out by the doctor using the controller 17, which is connected via the switch 20 to the unit 12 for adjusting the value of the additional constant component. When conducting remote electroanalgesia, unit 14, with its first input and output, connects via switch 18 to unit 1 of rhythmic action, which allows for a smooth increase in the average current value by adjusting the pulse frequency, which changes the intensity of the impulse effect. 6-8 By its second output, the remote electroanalgesing unit 14 via the switch 19 is connected to the pre-amplification unit 7, and the third output via the switch 20 to the adjustment unit 12 of the additional constant component, which allows for a decrease or increase in the amplitude of the pulses and additional constant level. Switches 18, 19, 20 allow you to control the process of remote electroanalgesia with the help of block 14 at a distance and, if necessary, allow you to selectively control the individual parameters of pulsed impact I1 without transferring them to the remote control using regulators 15, 16, 17 When switching the operation mode 6 to the position P, the output of the unit 25 is connected to the input of the unit 7, which determines the ability to operate in the adjustable duty cycle mode. In this case, the adjustment of the duty cycle is carried out using a regulator 27 connected via switch 26 to block 25, or using a remote control 14 connected by its fourth output to the input of switch block 26. The device allows, when conducting remote electroanalgesia, to use, along with other parameters of the pulse effect, the adjustment of the pulse duration, which provides an increase in the depth of the effect. In this case, it is possible to use the mode of operation with an adjustable pulse duty cycle in the course of treatment and anesthesia while stabilizing the pulse effect. When working with a variable duty cycle, the device has a special alarm system, which determines the possibility of disrupting oscillations of an abrupt change in the pulse frequency.
