The multimodal exposure unit contains acoustic emitters (headphones) and a video image generator made in the form of television glasses.

The design drawback of this device is the limited number of types of effects on the human senses, the lack of means for recording the response of the human body to multimodal effects, and the lack of means for generating the corresponding effects on these reactions (biological feedback (BFB)).

These shortcomings reduce the ability of the device to relieve the psychophysiological stress of a person and, first of all, the absence of the specified BH.

The control signal generation unit is made in the form of a tape recorder with magnetic tape with a recording of the control program. The exposure signal generation unit comprises a digital-to-analog converter, the outputs of which are connected to the impact signal generators. One of the sensors of the patient’s functional state (breathing sensor) is installed on the back of the device’s chair, and the other (skin-galvanic reaction sensor) is installed on the armrests of the chair.

The disadvantage of this design of the device for removing psychophysiological effects is the implementation of the control signal generation unit in the form of a tape recorder, the presence of a chair, the installation of sensors on the patient’s functional state, the placement of the control panel in the device’s equipment cabinet.

These shortcomings do not allow the patient to use the device on their own without assistance. It is difficult to use the device even with outside help for patients with bed rest and disabled people who do not correspond in size and proportion to the parameters of the chair and the location of sensors and means of exposure on it.

The bulkiness of the device as a whole limits the possibility of its movement and, as a result, limits the possibility of using the device to relieve the psychophysiological stress of a person in real conditions of his existence.

Blocks I.I, 1.2, 1.3 of console I are connected via a detachable cable connection 12 with the control signal generation block 2 of the hardware block 8. Block 2 is made in the form of a single-chip computer, for example,

 -t- 9MU339 models

integrated circuit КР 1816 BS 31. The output of block 2 is connected to the input of the decoder 3, the potential outputs of which are connected to the control inputs of the noise generator 4.4, sound signal generator 4.1, the first signal converter 4.5, the second signal converter 4.7, the electronic key block 4.8, block 4 , a video generator and a light beam emitter 5.5, unit 5. The decoder 2 is made on the 155 series microcircuits.

The generator 4.1 contains a series-connected memory block, a reader and an audio frequency amplifier, the output of which is connected to the signal inputs of the first signal converter 4.5 and mixer 4.6. The control input of the reader device of the generator 4.1 is connected to the control input of the latter. Converter 4.5 contains a series-connected block of band-pass frequency filters and a block of amplifiers, the outputs of which are connected to the emitters of color signals 5.4 of block 5. The second input of the mixer 4.6 is connected to the output of the second signal converter 4.7. Converter 4.7 contains a series-connected frequency-controlled sound generator and a controlled amplifier. The control input of the sound generator is connected to the output of the sensor of skin-galvanic reactions 7. The control input of the amplifier is connected to the control input, and the output with the signal output of the unit 4.7. The sensor 7 is made in the form of a sensor of the ohmic resistance of the patient’s skin, for example an ohmmeter. Structurally, the measuring part of the sensor 7 can be made in the form of two silver chloride rings or stainless steel, separated by a dielectric ring, and worn on the patient’s finger (figure 2).

The output of the mixer 4.6 is connected to the block of emitters of acoustic waves 5.3, and its third input is connected to the output of the noise generator 4.4, the modulation input of which is connected to the input of the comparator 4.3 and the input of the light beam emitter 5.5 directly and through amplifier 4.2 to the output of the respiratory signal sensor 7. V in the simplest case, the respiratory sensor 6 can be made in the form of a microphone installed in block 5 (figure 2). Possible implementation of the sensor b in the form of a capacitive or inductive type sensor that records the process of breathing through registration of movement of the patient's chest.

The output of the comparator 4.3 is connected to the signal input of the electronic key block 4.8. Block 4.8 contains three groups of power electronic keys, the control inputs of which are connected through a decoder to the control input of block 4.8, and the outputs, respectively,

a block of thermodes 5.1, a video generator 5.2 and an output 9 of switching external devices of multimodal effects, for example, odor generators, electrical stimulators, etc. The video generator 5.2 contains a series-connected memory block with a reader connected to the control input of block 5.2, a digital-to-analog converter, and a video projector with a screen. In the simplest case, the generator 5.2 can be made in the form of an electromechanical slide projector with a slide cassette and a screen.

The acoustic wave emitters of block 5.3 are transducers of electrical vibrations of sound frequency into acoustic waves and are made in the form of telephones or speakers installed in block 5 on its movable elements (FIG. 2). The block of emitters 5.4 contains electric lamps or LEDs of various colors connected to the control inputs of the block 5.4.

The light beam emitter 5.5 in the simplest case contains an electric lamp with a power supply unit, a reflector, a diaphragm and an electric motor, the electric lamp being installed at the focus of the reflector, the diaphragm mounted on the path of the light beam and connected by a kinematic link to the electric motor, the output of which is connected to the signal input of block 5.5. The control input of block 5.5 is connected to the power supply unit of the electric lamp.

Structurally, the elements 5.1, 5.5 are combined into a separate block of multimodal influences 5, mounted movably relative to the hardware block 8 using the kinematic link 10. The kinematic link is made in the form of several segments (figure 2) of hollow pipes interconnected with block 5 and block 8 by hinges compounds with three degrees of freedom. A multicore cable is laid inside the pipes of link 10, connecting the corresponding electronics elements of blocks 5 and 8.

To avoid overturning of the hardware unit 8 at a maximum distance of the unit 5 from the unit 8, the latter is equipped with a retractable stop II. To ensure the possibility of thermal effects in the palm of the patient’s hands and the convenience of taking parameters of his skin-galvanic reaction, part of the block 5.1 thermodes and sensor 7 are placed on the control panel I. These elements are connected to block 8 through the corresponding cable strands 12.

Block polymodal influences 5 (figure 2) has a recess of the corresponding form to accommodate the patient's face. Thermodes are installed on the two inner sides of block 5 at the level of the human cheeks

5.X, and at the level of the ears on the mobile elements phones 5.3. Before the eyes, a screen is installed inside the block 5 case, onto which the video image of the generator 5.2 and the perpendicular section of the light beam of the generator 5.5 are projected.

The color signal emitters of block 5.4 are installed on the internal machines of block 5 between the screen and the patient’s eyes outside the main field of view of the latter.

The operation of the proposed device is as follows:

Before starting a psychotherapy or training session, the apparatus unit 8 of the psychophysiological stress relieving device is installed near the patient’s bed or chair so that the retractable stop II prevents the unit 8 from turning over when the unit 5 is installed in the patient’s face. The patient puts the remote control in front of him (for example, being in his chair on his knees). Inserts the required memory block I.I into the remote control I (with the selected session program record). He puts on one of his fingers the rings of the skin-galvanic reaction sensor 7. He puts block 5 on his head, puts his palms on the thermodes of the console I and presses the start program key for the session on the typed field 1.2 ..

In this case, the start pulse of block 1.2 is supplied to the block for generating control signals 2. In this case, a single-chip computer is turned on and sequentially in time reading of control commands for multimodal influences recorded in the memory block I.I. In this case, the code sequence of pulses from block 2 is sent to indicator 1.3 and decoder 3. At the same time, the indicator LED 1.3 corresponding to the action being switched on is lit on indicator 1.3.

The code sequence of pulses from block 2 to decoder 3 is decrypted. In this case, a unit voltage is issued from the corresponding potential output of the decoder to the control inputs of the blocks 4.1, 4.2, 4.4, 4.6, 4.7, 4.8, 5.2, or 5.5 sequentially in time and in accordance with the action program recorded in the I.I. memory block

When a signal arrives at block 4.1, the latter turns on and generates sound frequency signals (for example, music or speech) sequentially in time. Sound frequency signals from block 4.1 are fed through a mixer 4.6 to the block of acoustic emitters 5.3 and the signal input of the first transducer 4.5. In block 4.5, if there is an enable signal from decoder 3 on its control input

filtering (allocation) of frequency bands from the spectrum of signals arriving at its signal input. These signals from each individual band-pass filter are amplified and fed to the corresponding color emitters of block 5.4. In this case, block 5.4 emits signals of the visible range of electromagnetic waves that vary in amplitude and color, depending on changes in the amplitude and spectrum of sound frequency signals received at the input of block 5.4. Upon receipt of an enable signal at the control input of block 4.2, amplifier 4.2 amplifies the breathing signals from sensor 7. These signals are transmitted to a noise generator 4.4 to a light beam emitter 5.5 and to a comparator 4.3. Under the influence of the signals coming from the decoder 3 and block 4.2, the noise generator 4.4 is modulated. A noise signal modulated by breathing signals (Fig. 3a) and control commands from block 4.4 through a mixer 4.6 is supplied to the block of acoustic emitters 5.3. At the same time, the patient hears a noise signal with the frequency of his breathing or the frequency set from the decoder 3. The amplified breathing signals received at the input of block 5.5 in the presence of an enabling signal at its input modulate the beam divergence. At the same time, a circle is projected on the screen of block 5, the diameter of which changes with the person’s breathing rate. The breathing signal received at the input of the comparator 4.3 is converted in the last of the analog form into a discrete one.

Rectangular pulses with a repetition period equal to the patient's respiratory rate from block 4.3 are fed to the signal input of the electronic key block 4.8. If there are permissive signals at the control input of block 4.8, the latter generates powerful rectangular pulses that repeat the shape of the input signals and outputs them to blocks 5.1, 5.2 and output 9 for switching external devices of multimodal effects. In this case, the block 5.1 thermodes with a respiration frequency emit streams of thermal waves acting on the cheeks and palms of the patient (figure 2).

Under the influence of the pulses coming from the decoder 3 to block 5.2, the appearance of the image (paintings, drawings) on the screen of the specified block changes. Under the influence of pulses coming from block 4.8 (with the appropriate resolution on block 4.8), the brightness of the image on the screen changes in accordance with the respiratory rate of the patient.

If there is an enable signal at the input of the second transducer 4.7, the latter converts the signals of the skin-galvanic reaction of the sensor 7 into an audio signal. In this case, the frequency of the signals of the sound generator of block 4.7 is proportional to the degree of excitation

(sweating) of a person during the session (figzb). The specified signal from the output of block 4.7 passes through a mixer 4.6 and enters the block of acoustic emitters 5.3 and acts on the ears of the patient.

Under the influence of polymodal influences, including the voice prompt from block 4.1 and biological feedback through block 6 and block 7, the patient adjusts his breathing in the direction of respiratory depression and mental stress in the direction of decreasing the sound frequency of the generator 4.7.

In this case, the psychophysiological stress is relieved not only due to excitations pleasant for the human senses, but also due to the efforts of his will.

Focusing on the process of reducing psychophysiological stress, contemplating pleasant images, for example, nature pictures, auditory perception of soothing sounds, color music 5.4 slows down the psychophysiological processes in the patient's body up to deep sleep.

In the event of an adverse effect of the selected program on the patient using the keys of the dialer field 1.2 and indicator 1.3 of the remote control I during the session, the volume of polymodal influences can be changed or the program can be completely changed by replacing the memory block 1.1.
