Description

The invention relates to medicine, namely to methods of physiotherapy.

In medical practice, methods of physiotherapy have been widely used by local exposure to the focus of pathology with an alternating electromagnetic field [1].

To implement these methods, magnetotherapeutic devices with an operating frequency of 50 Hz are used, for example, the Magniter apparatus. The device generates a sinusoidal and pulsating magnetic fields and is made in a single construct of an electromagnet inductor and a converter. The converter generates current pulses supplying the electromagnet winding.

Known methods of physiotherapy in which the human body is affected by a spatially organized electromagnetic field. For example, in a stationary apparatus "Magnetizer" (Japan) of type M - GHR, five inductors of electromagnets are used located on a chair [1].

A new stage in the development of electromagnetotherapy is characterized by the awareness of the need for exposure to an electromagnetic field on the entire human body. In this case, devices for therapy do not contain separate emitters and their sets, but a system of inductors organized and functioning according to certain rules.

One of the representatives of the apparatuses of general influence is the magnetotherapeutic installation of the Magnitor-AMP type, the radiating device of which is a stator of a 3-phase 2-pole alternating current machine. A uniform rotating magnetic field is created in the installation, affecting the entire patient’s body. Operating frequency 50 ... 60 Hz. The design is distinguished by its large mass (600 kg) and significant energy consumption (2.5 kW) [1].

The facility is used to treat patients with various diseases, including oncology [2].

With a local exposure to an electromagnetic field on the pathology site, there are restrictions on the use of this method for a number of diseases, including cancer.

A known method of physiotherapy by exposing the entire human body to a low-frequency electromagnetic field. To implement this method, an Aurora-MK electromagnetotherapy device containing a planar magnetoscan is used, in which the system of inductors is located in two surfaces: the lower one is straight and the upper one is curved [1].

The lower surface is the surface of the couch, and the upper is the lifting canopy. Inductors are placed in rigid planes.

All inductors are powered by a common electronic block, which provides the formation of an electromagnetic field. The frequency of the electromagnetic field is in the range of 0.1-100 Hz.

The disadvantages of the known device class "Aurora-MK":

- low-frequency electromagnetic field;

- high energy intensity;

- a large mass of inductor emitters;

- exposure to a single frequency signal.

The basis for the development and design of electromagnetic exposure devices should be based on the following criteria: treatment effectiveness; comfort for the patient; convenience and ease of maintenance for medical personnel; manufacturability in production; cost price; energy intensity, etc.

The main criterion is the effectiveness of the treatment.

Currently, medical devices are used for the general effect on the body, which use a low-frequency electromagnetic field generated by a signal with a carrier frequency of 50 Hz. It is known that cells are surrounded by extracellular fluid with a conductivity at a frequency of 50 Hz approximately 10,000 times higher than the conductivity of cell membranes. Therefore, at a frequency of 50 Hz, extracellular fluid effectively shunts the cells, creating pathways for the currents induced in the tissues by the electromagnetic field [3, 4, 5].

Therefore, only a very small part of the induced current flows through the cell membranes and is thus involved in the excitation of the cell.

Studies of scientists from many countries have shown that the electromagnetic field formed by amplitude-modulated sinusoidal signals with a carrier frequency selected in the frequency range 100-1000 kHz most effectively affects the body. However, at present, the industry produces magnetotherapeutic devices with a general effect only at a frequency of 50 Hz. These devices have a large power consumption and weight, inconvenient to maintain.

Of practical interest is the proposed method of physiotherapy, in which a high-frequency electromagnetic field is applied to the entire patient’s body, except for the focus of the pathology. In this case, a higher therapeutic effect can be obtained, especially in the presence of cancer.

The objective of the invention is the expansion of therapeutic and operational capabilities.

This is achieved by the fact that in the method of physiotherapy, including exposure to an electromagnetic field on a human body, according to the invention, the entire human body, except for the focus of pathology, is exposed to a high-frequency electromagnetic field formed by sinusoidal signals with carrier frequencies in the frequency range 100-1000 kHz, which are amplitude modulated by a low-frequency signal with a constantly changing frequency in the frequency range 10-10000 Hz and amplitude, using a system of flat local impact devices, each of which contains there is an emitter made in the form of an inductor, the winding of which is placed on a flat dielectric frame and is an integral part of the LC-oscillatory circuit, with the first half of the local exposure devices placed under the patient, and the second half above the patient, the head is exposed to a separate exposure device, containing an emitter made in the form of an inductor, the winding of which is placed on a cylindrical frame, the electromagnetic field strength at the surface of each element of the air The action should be in the range of 100-1000 mV / m, the duration of the procedure is 20-30 minutes, the procedures are carried out daily for 15-20 days.

This is achieved by the fact that in the device for physiotherapy containing a couch made of a dielectric, on which the system forming the electromagnetic field is mounted, fixed in two surfaces rectilinear and curvilinear, the control unit and the power supply voltage, according to the invention, the system forming the electromagnetic field is made in the form of M sections mounted on the plane of the couch and a separate apparatus of influence, each section contains a plane on which P local apparatuses of influence are placed, and a canopy on which R local exposure devices are located, each local exposure device contains a rectangular case made of a dielectric, in which a radiator is mounted, made in the form of an inductor, the winding of which is placed on a flat dielectric frame and is an integral part of the LC-oscillatory circuit included in the oscillator circuit, the modulator output and the input of the control path, which contains an amplitude detector connected in series, are connected to the oscillator circuit, the amplifier is constantly current and light indicator, circuits of the oscillator, modulator and control path are located in the housing of the local exposure apparatus, a separate local exposure apparatus contains an emitter made in the form of an inductor, in which the winding is placed on the side surface of the dielectric frame, having the shape of a cylinder, and is a composite part of the LC-oscillatory circuit included in the oscillator circuit, the modulator output and the input of the control path containing the connected In particular, an amplitude detector, a direct current amplifier and a light indicator, circuits of the oscillator, modulator and control path are located in a separate dielectric housing mounted on a cylindrical frame, a separate exposure apparatus is mounted on the plane of the couch with the possibility of its movement, the device contains a sound reproducing player with magnetic tape, which recorded a low-frequency signal that varies in frequency in the frequency range 10-10000 Hz and amplitude, and a power amplifier, in which the input is connected to the output m of a sound-reproducing player, and the output is with the input of a modulator of each local exposure apparatus, each oscillator generates sinusoidal oscillations with a carrier frequency selected in the frequency range 100-1000 kHz by an amplitude-modulated low-frequency signal with a constantly changing frequency in the frequency range 10-10000 Hz and amplitude .

The essence of the invention lies in the fact that during physiotherapy they affect the entire human body, except for the focus of pathology, with a high-frequency electromagnetic field formed by a sinusoidal signal with a carrier frequency located in the frequency range 100-1000 kHz, which is amplitude-modulated by a low-frequency signal with a constantly changing frequency in frequency range 10-10000 Hz and amplitude. The exposure is carried out using a system of flat local exposure apparatuses and a separate local exposure apparatus intended for the patient’s head.

Each of the apparatuses of influence contains a rectangular dielectric housing of small height, inside of which a radiator is fixed, made in the form of a flat inductor, the winding of which is an integral part of the LC-oscillatory circuit included in the oscillator circuit. The oscillator generates sinusoidal oscillations with a carrier frequency in the frequency range 100-1000 kHz, amplitude-modulated by a low-frequency signal with a constantly changing frequency in the frequency range 10-10000 Hz and amplitude.

The local impact element has free movement and is installed on the plane of the couch. If necessary, foam rubber is placed under it.

The method of physiotherapy is as follows.

All sections are mounted on the couch plane. The carrier frequencies of the local oscillation elements oscillators are located in the frequency range 100-1000 kHz. The frequencies of auto-generators of adjacent impact devices should differ by more than 1.2 times. The cables of all impact devices are connected to the outputs of the control unit and the source of supply voltage. The canopies of all sections are raised. On the control unit 17 set the exposure mode. The device has a number of modes (simultaneously by all exposure devices, alternating, etc.). There are a number of magnetic tapes for the player with different modulation modes. Before the procedure, a magnetic tape with the required modulation mode is installed in the player. Set the required electric field strength. Set the procedure time. The planes of the sections are covered with a sheet. The patient is placed on the couch. Local exposure devices located under and above the focus of the pathology are determined. They are turned off for the duration of the procedure. A local impact apparatus with a cylindrical coil is mounted on the patient’s head. Shed the canopies of all sections. Turn on the device circuit. In the presence of power, the emitter of each local influence element generates in space an electromagnetic field formed by a sinusoidal signal with a carrier frequency in the range of 100-1000 kHz with an amplitude-modulated low-frequency signal with a constantly changing frequency in the frequency range of 10-10000 Hz and amplitude. In the presence of a high-frequency signal, the indicator light of each local exposure device is lit. Conduct a session of electromagnetotherapy. After the procedure has expired, all auto-generators are turned off. The technical result is the recovery of the entire patient's body. The effect of an electromagnetic field on an organism has an immunostimulating effect [2, 4].

The positive therapeutic effect of exposure to a complex electromagnetic field is explained by improved blood flow, increased blood circulation, decreased spasms, normalization of vascular tone and elasticity. Under the influence of electromagnetic radiation, an increase in the diameters and number of functional capillaries occurs, blood pressure and nervous system excitability decrease, and protein and carbohydrate metabolism improve. The non-specific nature of the therapeutic effect of the electromagnetic field can be combined with pharmacological correction. Clinical observations show that despite the high efficiency (from 70 to 80%) of independent electromagnetotherapy, the combined effect, in which drug treatment is carried out against the background of electromagnetotherapy, is more effective (from 80% to 92%). The device is technologically advanced in production, has a low power consumption. Convenient for maintenance by medical personnel. With the proposed design of the device, the operation of laying down the patient is maximally simplified and its comfortable location is ensured.
