The invention relates to medicine, in particular to psychorelation, and can be used for the functional treatment of patients with neurosis with anxiety-phobic symptoms, as well as for the prevention of psychosomatic diseases and increase mental stress resistance.

The purpose of the invention is to expand the scope.

The drawing shows a functional diagram of the proposed device.

The device contains a random pulse generator 1, a first element And 2, a low frequency generator 3, a regular pulse generator 4, a second And 5 element, a high frequency generator 6, a first vibrator 7, a voltage-frequency converter 8, a frequency comparator 9, an element NOT 10, an RAG signal amplifier 11 with electrodes, a second vibrator 12, a third AND element 13, an electric cutter shaper 14.

The output of the random pulse generator 1 is connected to the first inputs of the elements And 2 and 4, the second inputs of which are connected to the first and second outputs of the regular pulse generator 4. The outputs of the elements And 2 and 5 through the contacts of the two-band switch P1 are connected respectively to the inputs of the low and high frequency generators 3 and 6. The outputs of which are connected to the first input of the frequency comparator and the first vibrator. The output of the amplifier 11 of the RAG signal is connected through the voltage-frequency converter 8 to the second input of the frequency comparator 9 and the second vibrator 12, and the output of the frequency comparator 9 is connected to the second input of the third element And 13, the output and the first input of which are connected to the third contacts of the first and the second pole of the switch P1, respectively, the second contacts of the first and second poles of the switch P1 are connected respectively to the output and input of the element HE 10, and the first contacts of the switch P1 are free. The movable contacts of the second and first poles of the switch are connected respectively to the second output of the high-frequency generator 6 and the shaper 14EKR ..

A random pulse generator 1, made, for example, on a shift register with feedback, forms at its output a quasi-random pulse sequence with an average period of 15 ... 20 s. The generator 4 of regular pulses together with the elements And 2 and 5 forms a random pulse distributor used to alternately start the low and high frequency generators 3 and 6,

moreover, the ratio of the frequencies of the automatic presentation of high and low tone signals is determined by the duty cycle of the pulses generated by the generator 4 regular pulses (e.g. 1: 3).

At the second output of the generator 6 high

frequency is set to logical 1 during the generation of oscillations, and in pauses is stored logical O.

When the contacts of switch B1 are open, the stimulus signals are supplied manually using the buttons Kn 1 and Kn 2.

Shaper 14 ECR can be made in the form of a capacitor with a capacity of ... 10 μF, charged with a voltage converter and discharged through a current stabilizer (1.5 ... 2.0 mA) and the skin of the patient at the time of arrival of control impulse.

Amplifier 11 of the RGR signal with an adjustable gain, which can be performed on an operational amplifier, provides amplification of the variable (physical) component of the RGR signal. .

The voltage-frequency converter 8 converts the instantaneous value of the amplitude of the RGR signal into

0 harmonic signal of constant amplitude with a proportionally varying frequency in the range from tens to hundreds of hertz.

Frequency to Omparator 9 forms on

5 output signal Logic 1 when the instantaneous value of the frequency of the biological feedback signal (proportional to the amplitude of the RAG) exceeds a fixed value of the frequency of the high-frequency stimulus (6.7 ... 0.8 of the maximum frequency of the biological feedback signal).

The bipolar three-position switch P1 allows you to select one of

5 of the three operating modes of the device, the first contact of both poles of the switch being not used.

The vibrators 7 and 12 are identical and are electromagnetic or electrodynamic heads, the membranes of which have mechanical contact with the skin and the vibration amplitude of about 0.1 mm.

The operation of the device is based on the case of automatic stimulus signals.

In this case, the switch B.1 is set to the closed position, ensuring the passage of random pulses to the inputs of the generators 3 and 6. On the human body, for example, on the palm and on the wrist, two pairs of electrodes are connected, respectively connected to the amplifier 11 of the RAG signal and shaper 14 ECR. Vibrators are placed in any convenient place so that the distance between them is 2 ... 5 times greater than the differential spatial threshold for the corresponding part of the body, for example, on the back surfaces of the palms of the left and right hands.

Since the voltage at the first output of the generator 4 of the regular pulses is inverse with respect to the voltage at its second output, the pulse from the generator 1 can go through only one of the elements And 2 or 5, respectively, start the generator 3 or 6 which form low or high frequency oscillations of about 10 seconds duration on the first vibrator 7.

The second vibrator constantly supplies voltage from the output of the VLF, the frequency of which varies in proportion to the amplitude of the RAG signal, which allows the patient to constantly monitor the change in his emotional stress: the higher the vibration frequency, the greater the amplitude of the RGR signal and, therefore higher emotional stress. Adjusting the transmission coefficient of the signal amplifier UGR.1 compensates for individual differences in the amplitude of the physical component of the RGC and is carried out before starting the session so that the amplitude of the approximate RGC to an unexpected stimulus (clap, electrocutaneous irritation, etc. .) was sufficient to increase the frequency of the biofeedback signal (oscillations of the second vibrator 12) to a level exceeding the frequency of the high current oscillations generated by the generator 6 by about 1.2. 1.4 times.

At the first stage (contacts of switch P1 in the upper position), the patient becomes accustomed to stimulus signals of high and low frequency in the absence of electrodermal irritation at any value of the amplitude of the RGC signal. As the level of oscillation of the second vibrator becomes more accustomed during the generation of high and low frequency stimuli, it decreases. An objective sign of the end of the first stage of training is the localization of fluctuations in the frequency of feedback oscillations in the low frequency region both in the pauses between stimulus signals and when they are presented.

At the second stage, the switch P1 is set to the second position, which ensures the signal from the second output of the high-frequency generator b passes through the element 10 to the input of the ECR driver 14. The HE element 10 provides the positive voltage drop necessary for starting the ECR driver 14 at the moment the high-frequency stimulus signal ends.

In the third step, the switch P1 is set to the lower position, allowing the signal to pass from the output of the frequency comparator 9 through the AND element 13 to the input of the ECR driver 14 only during the action of the high frequency stimulus. If the frequency of the feedback signal exceeds the frequency of the signal from the generator b, then the frequency comparator 9 goes into a single state, which causes the operation of the ECR driver 14. Otherwise, there is no electric shock. In order to reduce the degree of increase in the oscillation frequency of the second vibrator 12 during the action of the high-frequency stimulus, the patient avoids unpleasant electro-skin irritation, thereby acquiring the skill of emotional self-regulation under the control of tactile feedback.

The advantage of the present invention over the prototype is the ability to learn the skills of emotional self-regulation of people with various visual and hearing defects (up to their complete absence), as well as the possibility of training in almost any conditions (for example, in public transport, during a break at the workplace etc.), thanks to the small size and power consumption.
