Description

The invention relates to medicine, medical technology and can be used to treat various diseases.

Known devices for physiotherapeutic low-frequency electromagnetic exposure, in which the therapeutic effect is achieved by combining a mechanical one-time or multiple-time movement of a constant magnetic induction created by a ring permanent magnet and a low-frequency electromagnetic energy emitted by an injection semiconductor laser placed along the axis of this ring magnet, provided the laser is modulated by short positive, decreasing to zero pulses of low-frequency oscillations / 1, 2 /.

There is another device for physiotherapeutic low-frequency electromagnetic exposure, which creates the effect of superposition of two physical factors: low-frequency alternating magnetic field and vibro-acoustic vibrations of the frequency range 0.02 ... 20 kHz / 3 /.

It is also known a device selected as a prototype, which creates the influence of a pulsed electromagnetic field in the range of 20 ... 80 Hz, converted into a quasi-stationary electrostatic field orthogonal to the patient’s body, together with a discrete electromagnetic field created by the LEDs of the visible part of the spectrum / 4 / not correlated with the field of the frequency range 20 ... 80 Hz.

The disadvantages of this device are:

lack of tight synchronization in time from the beginning of exposure and during exposure to pulsed electromagnetic effects and the electromagnetic field of LEDs;

the lack of distinction, and therefore the accuracy of the installation, of frequencies for orientational polarization and for induced polarization, creating various reactions of muscle tissue and other organs of the patient during treatment.

The device is necessary so that, at a repetition rate of unipolar positive pulses decreasing to zero with a frequency of 80 ± 5 Hz, in addition to orientational polarization, additionally induced polarization can also be induced due to the patient’s muscle tissue falling into the region of resonant displacement — the displacement and deformation of each charged ion relative to other ions , that is, with a pronounced effect of resonant displacement and mechanical irritation weaved people / 5 /.

Induced polarization will also occur due to the patient’s muscle tissue entering the atomic resonance region, the effect of which is caused by the displacement and deformation of the whole ion lattice relative to other ions, the resonant displacement and mechanical irritation of the weavers, possible at a frequency of 132 Hz.

Induced polarization also arises due to the penetration of muscle tissue into the region of electron resonance, caused by a shift of the center of electrons in the molecule relative to the centers of positive ions, causing the effect of resonance bias and irritation of the patient's tissue at a frequency of 147 Hz / 5 /.

The frequencies of 132 Hz and 147 Hz in the prototype device and analogues are not singled out.

At the other frequencies of the low-frequency range, upon application of an alternating low-frequency field, the effect of establishing the rotation of constant dipole molecules, that is, establishing only orientational polarization / 5 /, passed.

In this regard, the formation by the device of influencing factors at frequencies (80 ± 5) Hz, 132 Hz and 147 Hz allows to increase the efficiency of low-frequency electromagnetic effects in the treatment of various diseases.

The application of a static / quasistatic / field created by the prototype device is equivalent to establishing a field-oriented polarization at zero frequency.

The therapeutic factor for all orientational polarizations is low-frequency thermodynamic volume heating of low intensity due to the movement of tissue particles.

The technical result consists in increasing the effectiveness of the therapeutic effect due to the combined synchronous exposure to a low intensity alternating magnetic field and the radiation of an injection low-intensity laser.

This is achieved by the fact that the device for physiotherapeutic low-frequency electromagnetic exposure contains a master oscillator that generates short rectangular pulses with a repetition frequency of (80 ± 5) Hz, 132 Hz, 147 Hz, a counting trigger, a block of emitter followers connected between the output of the master oscillator and the input of the counting flip-flop, DC power supply unit, electromagnetic inductors connected in series, power amplifiers, the inputs of which are connected to the counter output, to the output - to inductors, sources laser radiation, made in the form of injection semiconductor laser diodes, blocks of regulators of power supply modes of laser diodes, each of which is connected to the first input of the corresponding laser diode, power supply blocks of gates of laser diodes, each of which is connected to the output of the emitter follower block and the output to the gate input of the corresponding laser diode, while each electromagnetic inductor and laser diode are combined into a single structural element, and the inductor winding is wound on a die ektrichesky frame, inside which is placed a movable core formed with longitudinal through hole, wherein the laser diode is mounted.

Clinical trials have shown that a device for physiotherapeutic low-frequency electromagnetic exposure provides restoration of blood flow deep in tissues, improves blood microcirculation and lymph formation, increases energy at the molecular and cellular levels, relieves muscle and joint pain, reduces tissue swelling, slows down and stops inflammatory processes, improves energy cellular potential, accelerates the resorption of traumatic bruising and hematomas, reduces tissue swelling, stops, or reduces muscle cramps, lowers cholesterol, strengthens collagen levels deep in tissues, activates protein synthesis, increases enzyme activity, stimulates factors of a specific and non-specific effect. In addition, instead of sequentially taking two physiotherapeutic procedures in time, the patient simultaneously takes these procedures. That is, the number of medical staff is reduced, and hence the cost of its payment. Reduces patient costs for medical services, patient costs for transportation and time.

Figure 1 presents the structural diagram of the device. Figure 2 shows a diagram of the structural combination of an electromagnetic inductor and an injection laser in the device.

A device for physiotherapeutic low-frequency electromagnetic exposure contains a master oscillator 1, the output of which is connected to the input of the emitter follower unit 2. The outputs of the emitter follower unit 2 are connected to the inputs of the gate power supply blocks 3 and the counting trigger unit 4. The gate inputs of the laser diodes 5 are connected to the outputs of the gate memory blocks 3, and the inputs of power amplifiers 6 are connected to the outputs of the counting trigger 4. The outputs of power amplifiers 6 feed a series connection of several electromagnetic x inductors 7. The remaining electrodes of the laser diodes 5 are powered from the regulation blocks of the laser diodes 8. In addition, for the operation of all blocks of the circuit, with the exception of blocks 5 and 7, it is necessary to supply power from the constant voltage supply unit 9.

The structural combination of the electromagnetic inductor 7 and the laser diode 5 in the device contains a cylindrical coil 10 of the inductor 7, wound on a cylindrical dielectric frame with an internal movable steel core 11, in which an injection semiconductor laser 5 is installed, the power and modulation wires are fed to the laser through a longitudinal hole 12 inside core 11. At the same time, the laser 5 is firmly pressed against the core 11 with a special union nut 13.

The device operates as follows. The master oscillator 1 generates short rectangular pulses with a repetition rate of (80 ± 5) Hz, 132 Hz, 147 Hz from the reference frequency of the range 20 ... 150 Hz, which are fed to the input of the emitter follower unit 2, amplifying and normalizing them in amplitude. From block 2 of the emitter followers, the pulse voltage is divided into 2 voltages: to the inputs of the gate power supply blocks 3 and to the input of the counting trigger 4. Formed by the gate power supply blocks 3 pulses of the start of lasers of the required polarity, amplitude and frequency from the outputs of these blocks go to the gate inputs of injection lasers 5. The pulses from the outputs of the counting trigger 4 are fed to the inputs of power amplifiers 6, which produce current pulses with a power sufficient to power several series-connected electromagnetic inductors 7.

Power supply of the circuit elements is carried out from the blocks of regulators of the power modes of the laser diodes 8 and from the unit of constant supply voltage 9.

The implementation of the claimed device was carried out on the basis of the use of schematic solutions worked out by industry organizations in the PDMT-01, Uzor, Lita-1 medical devices and their own circuit solutions. She showed the full performance and feasibility of subsequent use.

As injection semiconductor lasers, lpi-101 (lpi-102) and, in addition, lpi-30 lasers were used.
