Description

Studying medical devices for bioresonance therapy (BRT) among others, I thought about the possibility of combining music therapy with BRT. The idea came in the process of studying the technical characteristics of Amplipuls-5 Br, BIOMEDIS M devices, HiToP 184 high-tone therapy apparatus, POLYUS 101 magnetic therapy apparatus and others, well, the possibilities of music therapy are well known. Choosing a particular piece of music, the patient chooses the modulating form, depending on the rhythm and structure of the (frequency) piece of music, is the essence of biofeedback. BRT can be used in the treatment of a large number of diseases, and this combination method will enhance the therapeutic effect in the treatment of some diseases where BRT and music therapy can be applied. The device belongs to the family of devices for bioresonance therapy.

The essence of this idea is very simple: most BRT devices are structurally very similar and operate in two modes - they either feed a sinusoid to the electrodes mainly in the range of 1-20000 Hz, or high frequencies modulated by frequencies from the same range. If these frequencies are in the radio range, the device operates without contact with the patient's body.

The diagram indicated in FIG. 1 shows the functional (structural) diagram of the device. It consists of a circuit for decomposing a musical signal (block of band-pass filters), since such a signal contains, in addition to the fundamental frequencies and harmonics (overtones), which should be separated if possible. To do this, bandpass filters or amplifiers with such filters are introduced into the circuit. It was possible to simply apply the envelope (the effective value of the rectified signal) from the band of the strip amplifier (or filter) as in the color-music system, and apply it to the electrodes, but most devices output one frequency, usually in the range of 1-20000 Hz. For this purpose, a sinusoidal signal generator based on a specialized ICL8038 microcircuit is introduced into the circuit, a complex module that makes you think about the entire circuit. Pondering the contours of the future device, which include well-known components of circuitry, I tried to use, if possible, a modern, not very expensive, elemental base that simplifies the manufacturing process and tinctures. The sinusoidal signal generator on the ICL8038A microcircuit allows using a single regulator to obtain a sinusoid of any frequency from 0.1 Hz to 20,000 Hz at the output, and the driver modulator (or manipulator) allows you to modulate the envelope of the strip signal of the signal generator ICL8038. Here, the duration of the pauses is determined by the structure of the musical work, and the number of oscillations in the series by the frequency of the sinusoidal generator. Then, the modulated signal is fed to an amplifier 34 loaded on electrodes and, alternatively, to an LC circuit tuned to a signal of the desired frequency for magnetic therapy. Since the duration of the envelope period is large, frequencies in units of Hz can also be modulated.

For an example, we give a picture of the oscillograms of the device:

In (Fig. 3) waveform 1 signal from the strip of a strip amplifier, waveform 2 corresponding to it at the input of the manipulator, waveform 3 signal at the output of the device.

The circuit diagram is shown in the figure (Fig. 2): the circuit includes a strip amplifier on the K157UD2 op amp, an electronic switch on the KP547KP1, a sinusoidal signal generator on the ICL8038A chip, a power amplifier 34 on the TDA chip and a modulator (manipulator). The input and output voltage of a strip amplifier is 1-2 Volts, the envelope voltage at the input of the comparator is 1.5-2.0 Volts. The modulating voltage is removed from the output of the K521CA3 comparator at the level of 5 Volts, since it controls the manipulator on the ADG419BNZ chip (or on 2N4351 transistors and their analogs). To prevent the manipulator from distorting the generator signal during manipulation, the “zero cross” node was introduced on the K561TM2 chip. For the correct operation of this node, the in-phase signal from output 9 of the ILC8038A chip is used. The current value of the voltage at the output of the generator on the ICL8038A microcircuit will be 1-3 Volts, it will be a power amplifier up to 20-25 Volts at a load of 8-16 Ohms, this voltage will be regulated by a regulator placed on the panel, as well as its frequency. Further, the signal is applied to standard electrodes applied to the patient. The same signal can also be applied to the LC circuit, which includes an emitting toroidal coil for magnetic therapy. In the Russian and foreign markets, as well as sources of scientific and technical information available to me, no direct analogues of the proposed device have been found, but there are a number of physiotherapeutic devices produced in series.

Among them, the domestic physiotherapeutic apparatuses BIOMEDIS M, Amplipuls-5. 6.6 -4, K8, ElESKULAPMedTeKO, FS-100-4, ASB-2-1 m, Elem-1, are widely known. "ALMAG-01,02,03", "MEGATON" and others. Foreign analogues: HiTop-184 apparatus for physiotherapy (Germany), physiotherapeutic apparatus ERGON (Italy), physiotherapeutic combine INTELECT ADVANCED (USA).

The proposed apparatus in this area stands apart, since it is called upon to implement a slightly different idea combining music therapy with BRT (if necessary) and, in my opinion, has a number of advantages that can significantly increase the effectiveness of physiotherapy procedures:

the principle of biological feedback, in connection with which it becomes possible to achieve a synergistic effect during a physiotherapy session;

the possibility of selecting for each patient an adequate structure of the impact factor;

the channel of informational impact is connected parametrically with the channel of physical impact, which significantly enhances the physiotherapeutic effect;

excludes the reaction of rejection of factors of influence on the patient;

by ensuring the adequacy and optimality in the process of selecting an impact factor, with the help of the apparatus it is possible to achieve the effect of completely eliminating "addiction".

During a physiotherapy session using the apparatus under development, there is an increase in direct and inverse biological connections between various body systems, improving the adaptive ability and resistance of the body as a whole. The body acquires biological stability.

A schematic diagram of the device is attached to the report. It does not contain a microprocessor characteristic for such devices, which simplifies the circuit, repair and maintenance. The electrical safety of the device is ensured by a low output voltage, and the removal of the power supply in a separate case, which makes it possible to use a serial industrial power supply with a power of 25 watts. The circuit diagram is continuously being refined, eliminating omissions as experience is gained. The circuit is designed to build a test apparatus.

In conclusion, we give the main technical data.

Output frequency range 0.1-200000 Hz controlled Output voltage level 3-25 volts not controlled Electrode current level 1-60 mA controlled Power consumed by the device 25 watts Product Dimensions 300 × 260 × 100 mm
