Description

The utility model relates to physiotherapy, and more particularly to devices used to regulate a person’s brain activity in order to activate his intellect.

It is known (see Anna Wise, “Inspiration on order”, translated from English, Minsk, OOO Potpourri, 1998, p. 10) that the human brain constantly emits electrical impulses called waves of brain activity. By frequency, the waves of brain activity include alpha, beta, theta and delta frequencies. The combination of these waves determines the state in which the intellect is located. It was established (see ibid., P. 20) that an active state of intelligence is a state where a person simultaneously produces alpha, beta, theta, and delta frequencies in the right proportions. In this state, a person has a keen perception, creative inspiration, and is also in a state of easy relaxation and readiness for conscious thinking. In an active state, human intelligence works more quickly, accurately and efficiently than in other ordinary states. The thought process runs smoothly, without interference and inhibition. On the whole (see ibid., P. 8), “the effectiveness of intelligence is determined by the ability at any time to enter into that state of consciousness that is most suitable for the circumstances”.

A known analogue is the invention "Transcranial stimulator" according to RF patent No. 20033360, which includes a battery, a pulse voltage regulator, a voltage converter with forced excitation, a generator of periodic stimulation pulses, an output cascade and electrodes. The stimulator allows you to issue periodic rectangular symmetrical current pulses to the electrodes with a constant ratio between its constant and variable components with a front of 1 microsecond, a frequency of 500 hertz and a constant duty cycle of 4, and is intended for medical use for electrical stimulation of the subcortical structures of the brain in the treatment of pathological states of the central nervous system, arachnoiditis of the brain, neurosis, migraine, etc.

The disadvantage of the analogue - transcranial stimulator according to the patent of the Russian Federation No. 20033360 is a narrow area of its purpose, due to the fact that the device can only produce periodic rectangular current pulses of the same frequency of the line spectrum and cannot produce electric signals of the combined current spectrum similar to the electromagnetic spectrum of the human brain, which it is possible to regulate the brain activity of a person in order to activate his intellect.

Signs of the analogue of the invention according to the patent of the Russian Federation No. 2003360, which coincide with the essential features of the claimed utility model, are the power source (battery) and electrodes.

An analogue is also known - the invention according to the patent of the Russian Federation No. 2159639 "Method of transcranial electrical stimulation of the endorphin mechanisms of the brain and a device for its implementation." The device of this invention includes a series-connected periodic pulse generator, a filtering unit, a voltage-current converter, a current meter, a protection unit, and stimulation electrodes. In addition, the device includes a control unit, a keyboard unit, a musical speech unit, a non-volatile memory unit, an indicator unit, a test signal unit, biological feedback sensors and an amplifier converter. This device allows you to create periodic electrical rectangular pulses with a front and slice duration of not more than 20 microseconds, followed by a period of 12.9 ± 0.4 milliseconds with a duty cycle of 3.2-3.7. The device is intended for medical use and allows contacting pulsed exposure of the forehead and mastoid processes of the patient’s skull for 15-40 minutes to block pain, normalize blood pressure, stimulate the healing processes of damaged tissues, increase immunity, and relieve withdrawal symptoms with the help of periodic periodic pulses of electric current syndromes.

The disadvantage of the analogue - transcranial stimulator according to the patent of the Russian Federation No. 2159639 is a narrow area of its purpose, due to the fact that the device can only produce periodic rectangular current pulses with specific parameters of the line spectrum and cannot produce electric current signals of the combined spectrum, similar to the electromagnetic spectrum of the human brain, which it is possible to regulate the brain activity of a person in order to activate his intellect.

Signs of an analogue - invention according to the patent of the Russian Federation No. 2159639, which coincide with the essential features of the claimed utility model, are a power source, a current meter, a protection unit and electrodes.

In addition, an analogue is known - the invention "Device and method for increasing the amplitude of P300 waves in the human brain" according to US patent No. 5442410. The device according to this invention includes a power source, a periodic pulse generator, a current meter, a timer, switches, an output signal frequency regulator, a pulse width regulator, a pulse time delay regulator, a voltage and current regulator, as well as electrodes.

The device allows you to produce periodic electrical pulses in the form of a wave with a current amplitude in the range from 0.1 to 400 milliamps, a voltage of approximately 40 to 60 volts, a frequency of 0.1 to 400 hertz and a signal width of about 0.2 to 2 milliseconds in a 20% duty cycle. These periodic electrical impulses act on the human brain for at least 20 minutes to 2 hours. As a result, a person’s craving for alcohol and drugs is reduced, anxiety, insomnia and depression are reduced.

The disadvantage of the closest analogue is the device according to US patent No. 5442410, which we accept as a prototype, is also a narrow field of application due to the fact that the device can only produce periodic current pulses of a linear spectrum with specific parameters and cannot produce electric current signals of a combined spectrum , similar to the electromagnetic spectrum of the human brain, which can regulate the brain activity of a person in order to activate his intellect.

Signs of an analogue are the devices of US patent No. 5442410, which coincide with the essential features of the claimed utility model, are a power source, a current regulator, a current meter and electrodes.

The problem to which the claimed utility model is directed is to create a device that provides the ability to produce electric current signals of a combined spectrum, similar to the electromagnetic spectrum of the human brain, which can regulate the human brain activity in order to activate his intellect.

The problem is solved by the claimed as a utility model device for regulating brain activity. The device includes a power supply connected in series with each other, an electric signal generator of a combined spectrum similar to the electromagnetic spectrum of the human brain, a control unit, an electric current meter, a protection unit, and stimulation electrodes.

The technical result provided by the proposed device for regulating brain activity is the ability to produce adjustable currents of acceptable power at an acceptable voltage, electrical signals of the current of the combined spectrum, in the frequency range up to 200 ± 10.0 hertz, similar to the frequencies produced by the human brain in a state of active intelligence.

The main essential feature that distinguishes the proposed device from the closest analogue is a generator capable of producing electrical signals of a combined spectrum current in the frequency range up to 200 ± 10.0 hertz, similar to the frequencies produced by the human brain, and includes delta frequencies (in range from 0 to 4 ± 0.5 hertz), theta frequency (in the range from 4 ± 0.5 to 8 ± 0.5 hertz), alpha frequencies (in the range from 8 ± 0.5 to 14 ± 0, 5 hertz), beta frequencies (in the range from 14 ± 0.5 to 38 ± 5.0 hertz) and gamma frequencies (in the range from 38 ± 5.0 to 200 ± 10.0 hertz).

It has been experimentally established that, to simplify regulation, the amplitude maximums of the current strength for all the above frequency ranges can be equal to each other, without exceeding 36 milliamps.

The electrical waveform corresponding to this embodiment is shown in FIG. 1. On the ordinate axis is the amplitude of the current strength (mA) on a linear scale, on the abscissa axis is the frequency (Hz) on a logarithmic scale. Delta frequencies (δ), theta frequencies (θ), alpha frequencies (α), beta frequencies (β) and gamma frequencies (γ) are shown with amplitude maximums of current strength identical for all frequencies, not exceeding 36 milliamps.

The technical result provided by this variant of the proposed device for regulating brain activity is the ability to produce in the range up to 200 ± 10.0 hertz electrical current signals of a combined frequency spectrum similar to the electromagnetic frequency spectrum of the human brain in a state of active intelligence, with equal adjustable amplitude maxima of the current for all of the above frequencies, not exceeding 36 milliamps.

At the same time, it was experimentally established that, as an option, a more efficient form of the distribution of the amplitude maxima of the current can be proposed. In accordance with it, successively the amplitude maxima of the current strength of gamma, beta, theta, delta, alpha frequencies should be less than each other, and the amplitude maximum of the current strength of alpha frequencies should not exceed 36 milliamps.

The combined waveform electrical waveform corresponding to this embodiment is shown in FIG. 2. On the ordinate axis is the amplitude of the current strength (mA) on a linear scale, on the abscissa axis is the frequency (Hz) on a logarithmic scale. Delta frequencies (δ), theta frequencies (θ), alpha frequencies (α), beta frequencies (β) and gamma frequencies (γ) are shown, for which the amplitude maxima of the current strength are gamma, beta, theta, and delta , alpha frequencies are less than each other, and the amplitude maximum of the current strength of alpha frequencies does not exceed 36 milliamps.

The technical result provided by the second variant of the proposed device for regulating brain activity is the ability to produce electrical signals of the current of the combined spectrum, which consists of a combination of frequencies in the range from 0 to 200 ± 10.0 hertz, similar to the frequencies produced by the human brain in a state of active intelligence, in this case, successively the amplitude maxima of the current strength of gamma, beta, theta, delta, alpha frequencies are less than each other, and the amplitude maximum of the current strength of alpha frequencies does not exceed 36 m lliamper.

Block diagram of a device for regulating brain activity is shown in FIG. 3. The device includes a power supply 1 connected in series with each other, an electric signal generator of a combined spectrum 2, a control unit 3, an electric current meter 4, a protection unit 5 and stimulation electrodes 6. And in FIG. 4 presents a photo of a private embodiment of the inventive device with an indication of its main elements and the sources of information confirming the fame of such elements. A Panasonic Ni-Mn battery (https://panasonic.ru/products/eneloop/ni_mh_eneloop_pro.php) was taken as a power source 1. It is connected in series with an electric signal generator of combined current spectrum 2, made on the basis of the Iriver T60SE audio player (https://www.iriverrussia.com/catalog/player/30), with a control unit 3, made on the basis of the Zener diode BZT52C3VOS-7 (http : //www.datasheetarchive.com/BZT52C3V0S-7-datasheet.html) and OPA37GP operational amplifier (http: //pdf.datasheetcatalog.eom/datasheet2/3/069or7iy3i4usq2hflishd1zxxxxpy.pdf), with a current meter 4 Personal Scope HPS10 Velleman Instruments (https://www.velleman.eu/images/tmp/HPS10%20TD%20V1.1.pdf), with a protection unit 5 based on the LM348 operational amplifier (http: //www.ti .com / lit / ds / symlink / lm348-n.pdf), and with email electrodes 6. Structurally, in the particular case of the proposed device presented in the photo, the power supply 1, the control unit 3 and the protection unit 5 are placed in one housing.

Declare as a utility model, the device operates as follows. Power source 1 allows you to generate electrical signals of a combined spectrum with currents of low power up to 36 milliamps and low voltage up to 36 volts. The generator of electric current signals of the combined spectrum 2 produces signals in the range from 0 to 200 ± 10.0 hertz with frequencies similar to those produced by the human brain, and includes delta, theta, alpha, beta and gamma frequencies. The control unit 3 allows you to turn on and off the power source 1 and generator 2 and set using a current meter 4, the current strength for each of the frequencies in accordance with the selected version of the device. The protection unit 5 allows you to ensure the safe use of the device - disconnects the electrodes 6 when the stimulating current exceeds its permissible level, as well as in the event of malfunctions in the electrical circuit of the device. Stimulation electrodes 6 are placed on the skin of any parts of the user's body to close the electric circuit and ensure the subsequent transmission of electrical signals to his brain.

The regulation of the user's brain activity by the device proposed as a utility model is performed when the electric circuit is closed by the user’s body by acting on the user's brain by the electric signals of the combined spectrum current generated by the generator in the frequency range from 0 to 200 ± 10.0 hertz, which are similar to the frequencies produced by the human brain, including delta, theta, alpha, beta and gamma frequencies, and by regulating the amplitude maxima of the current for the above frequencies, without exceeding 36 milliamps R.

As a result of exposure to the user's brain by the electric current signals generated by the device, the combined frequency spectrum, similar to the frequencies of the brain in the state of his active intelligence, ensures the physiological nature of the electrical signals and the user's brain easily assimilates the signals coming from outside. As a result, the user enters and is in a state of active intelligence due to the influence of electrical signals of the current of the combined spectrum on the user's brain by a quasi-resonant mechanism.

It has been experimentally established that the time for the user to reach the state of active intelligence after the start of stimulation is from several seconds to 30 minutes and depends on the state of the user, his degree of preparedness and the environment. The time to reach the state of active intelligence is reduced, and the time it is held after the end of electrical stimulation increases with the psychic efforts of the user to create a state of active intelligence. The retention time of the state of active intelligence after the end of stimulation also ranges from a few seconds to 30 minutes. The effectiveness of regulation of brain activity and the achievement of a state of active intelligence by a user can be estimated objectively by changing the brain's electroencephalogram (EEG) by an electroencephalograph before the start of the exposure session, during the entire session and after it ends according to the amplitude-time and amplitude-frequency characteristics of brain activity. As an example, the corresponding EEGs performed by the monopolar method according to the standard system for placing electrodes on the surface of the head recommended by the International Federation of Electroencephalography and Clinical Neurophysiology - “10-20%” are given.

For clarity, the EEG of user C is given conditionally for the left and right hemispheres of the brain in the leads F3-O1 (Fig. 5) and F4-O2 (Fig. 6), respectively, performed before the start of regulation of brain activity in the form of an amplitude-frequency diagram characteristics (AFC), where along the abscissa axis is the frequency in hertz, along the ordinate axis is the amplitude in microvolts. In FIG. 5, the frequency range is indicated by 1, theta range by 2, alpha range by 3, beta range by 4, gamma range by 5. In FIG. 6, the delta frequency range is indicated by the number 6, theta range - by the number 7, the alpha range - by the number 8, the beta range - by the number 9 and the gamma range - by the number 10. Moreover, the EEG of the user C. in FIG. 5 and FIG. 6 is characterized in that theta ranges 2 and 7 are smaller than the alpha ranges 3 and 8, which are less than the beta ranges 4 and 9, which are less than the delta of ranges 1 and 6. Therefore, the user does not have active intelligence.

Brain activity of the left hemisphere in the F3-O1 lead in FIG. 7 and the right hemisphere in assignment F4-O2 in fig. User S. 8 displays the presence of active intelligence 15 minutes after connecting the proposed device to it. In FIG. 7, the delta frequency range is indicated by 11, theta range by 12, alpha range by 13, beta range by 14, gamma range by 15. In FIG. 8, the delta frequency range is indicated by 16, theta range by 17, alpha range by 18, beta range by 19 and gamma range by 20.

In this case, the amplitudes of the beta current of frequency ranges 14 and 19 are less than theta of ranges 12 and 17, which are smaller than the delta of ranges 11 and 16, which, in turn, are smaller than the alpha of ranges 13 and 18 for both hemispheres. Readiness for conscious thinking (beta frequencies) and a state of light relaxation (alpha frequencies) occur in 5-10 minutes, and states of creative insight (theta frequencies) and heightened perception (delta frequencies) appear 10-15 minutes from the start regulation of brain activity.

Brain activity of the left hemisphere in the F3-O1 lead in FIG. 9 and the right hemisphere in assignment F4-O2 in fig. User S. 10 displays the presence of active intelligence approximately 30 minutes after disconnecting the device from it. The state of active intelligence persists depending on the degree of fitness and the characteristics of the body. In FIG. 9, the delta frequency range is indicated by 21, theta range by 22, alpha range by 23, beta range by 24, gamma range by 25. In FIG. The 10th delta frequency range is indicated by 26, theta range by 27, alpha range by 28, beta range by 29 and gamma range by 30.

In this case, the amplitudes of the beta current of frequency ranges 24 and 29 are less than theta of ranges 22 and 27, which are smaller than the delta of ranges 21 and 26, which are less than the alpha ranges of 23 and 28 for both hemispheres, which indicates the presence of active intelligence. Readiness for conscious thinking (beta frequencies), a state of light relaxation (alpha frequencies), creative insight (theta frequencies) and heightened perception (delta frequencies) remain.

Several experimental devices for regulating brain activity, proposed as a useful model, have been fabricated and an experimental verification of their practical applicability and effectiveness has been carried out.

Before using the device, users of the device experienced significant difficulties in their chosen areas of activity.

Example 1. User A. 40 years old, tennis player (tennis). Lost the most significant sports for him.

After gaining theoretical knowledge and practical skills in regulating his brain activity, he applied a device for four weeks 1 hour per week to acquire and stabilize an active state of intelligence during a game of tennis. In this case, the amplitude maxima of the current in the delta, theta, alpha, beta, and gamma frequencies were equal to each other. The electrodes were placed directly on the skin of the user as follows: one electrode was located in the upper third of the right lower leg, and the second electrode was located in the upper third of the left lower leg. The user himself directly controlled the magnitude of the current by the control unit, guided by the data of the electric current meter.

As a result of using the proposed utility model, the user by the number of victories became the leader in his group of players.

Example 2. User O. 17 years old, tennis player (tennis).

She started systematic tennis lessons quite late for her age - from 12 years old. Despite the enormous hard work and desire to win, two years of intense training did not bring tangible results.

At the age of 14, she gained theoretical knowledge and practical skills in regulating her brain activity. I used the device in order to acquire and stabilize an active state of intelligence during a game of tennis. Electrodes were placed directly on the skin of the user in the region of the lower third of the legs. The user herself controlled the magnitude of the current by the control unit. At the same time, it set amplitude maxima in the gamma frequency range less than the amplitude maximum in the beta frequency range, which set less than the amplitude maximum in the theta frequency range, which set less than the amplitude maximum in the delta frequency range, which set less than the amplitude maximum in the alpha frequencies respectively. The time of electrical stimulation was 1 hour every other day for two weeks twice a year for two years and seven months.

When comparing the EEG performed before stimulation, during stimulation and 30 minutes after it ended, she had a stable state of active intelligence. As a result, she fulfilled the norm of a master of sports.

Example 3. User A. 25 years old, graduate student at the Pedagogical University.

Due to the need to study and work at the same time as a tutor, she had low academic performance in the main subjects at the university, she accumulated psychological fatigue, and she had the intention to go on academic leave.

During the year, she theoretically and practically engaged in the regulation of her brain activity. I used the device in order to acquire and stabilize an active state of intelligence during study and work as a tutor. Stimulation was carried out by electric combined current signals, and the amplitude maxima of all frequency ranges were equal to each other. Electrodes were placed directly on the skin of the user in the area of the right and left shoulder.

When comparing the EEG data performed before stimulation, during stimulation and 30 minutes after its completion, I had a stable state of active intelligence. As a result of stimulation, the effectiveness of our own training significantly increased, and academic leave was not required. The overall performance of her students improved qualitatively, which resulted in high scores in all subjects.

Example 4. User C. 40 years old, professional florist, sales consultant. When transferring to a new place of work, she experienced a creative crisis due to the fact that buyers rarely came to the flower shop, and the compositions compiled by her were not in demand.

Got theoretical knowledge and practical skills in regulating my brain activity. For six months, I used the device for the purpose of acquiring and stabilizing an active state of intelligence during the performance of my professional duties. Stimulation was carried out by electric current signals of the combined spectrum, and the amplitude maxima of all frequency ranges were equal to each other. Electrodes were placed directly on the skin of the user in the area of the right and left forearms.

When comparing the EEG performed before stimulation, during stimulation and 30 minutes after it ended, she had a stable state of active intelligence. By the end of the course of electrical stimulation, she increased the profits of a flower shop by 27%.

Example 5. User N. 57 years old, a professional trader. I was on the verge of bankruptcy due to the fact that the trading schemes tested earlier in the work did not bring profit, and the new ones that were created only increased losses.

Got theoretical knowledge and practical skills in regulating brain activity in himself. I used the device for two months 1 hour a day to acquire and stabilize the active state of intelligence while working on the exchange. The electrodes were placed directly on the skin of the user as follows: one electrode was located in the lower third of the right lower leg, and the second electrode was located in the lower third of the left lower leg. The user himself regulated the magnitude of the current strength by the control unit. At the same time, he set the amplitude maxima in the gamma frequency range less than the amplitude maximum in the beta frequency range, which set less than the amplitude maximum in the theta frequency range, which established less than the amplitude maximum in the delta frequency range, which set less than the amplitude maximum in the alpha frequencies respectively.

When applying electrical stimulation, objectively, according to the EEG data performed before stimulation, during stimulation and 30 minutes after its completion, he had a stable scheme of active intelligence. By the end of the two-month course of electrical stimulation, he had increased his work efficiency by 1.7 times in monetary terms.

Thus, it has been practically confirmed that the device for regulating brain activity proposed as a utility model allows the user to regulate their own brain activity and enter the state of active intelligence, save it using tools that can be used in the presence of third parties; including during public speaking, playing sports and performing other types of labor and especially public activities. Experimental verification, including the above objective data, confirmed the possibility and feasibility of practical applicability and effectiveness of the proposed device for regulating brain activity.
