Description

The physiotherapeutic device of electromagnetic influence "Homeoton" refers to the means of medical equipment and is intended for magnetotherapy or magnetic processing of food or external products.

One of the methods of physiotherapy is the impact on the tissues and organs of the human body with a magnetic field. The magnetic field has a wide range of biological effects that occur when exposed. The low-frequency magnetic field is characterized by the excitation of the peripheral nervous system, in contrast to the constant magnetic field, which exerts a inhibitory effect on it (Bogolyubov V.M. and Ponomarenko G.N. General physiotherapy. St. Petersburg: "SLP", 1997, p.157 )

In order to be able to act on tissues and organs located deep in the body, it is necessary to create a magnetic field powerful enough for this. At the same time, it is possible to avoid increasing the consumption of electric energy, and therefore be able to create portable devices with autonomous sources of electric power, by combining the action of a constant magnetic field (provides relatively deep penetration of the field into the body) and an alternating magnetic field (ensures the presence of a variable component in the resulting field) .

A similar approach in which a permanent magnet is designed to produce a constant magnetic field modulated by a pulsating magnetic field of a solenoid is known from the description of international application WO 2007/071543 A1, publication date 06/28/2007. A device for exposure to a magnetic field known from the specified international application contains a solenoid and a permanent magnet of corresponding length coaxially located inside it.

However, the known device when exposed to a low-frequency magnetic field will not allow a local therapeutic effect, without further adverse excitation of the peripheral nervous system. The known device can also affect only a relatively limited surface area

body.

The objective of this technical solution is to create a device devoid of these disadvantages, which leads to an increase in the effectiveness of physiotherapy.

The first technical result provided by the claimed technical solution is to reduce the spread of excitation of the peripheral nervous system outside the area of influence, which will improve the selectivity of magnetotherapy, with the effect mainly on selected tissues and organs.

The second technical result provided by the claimed technical solution is to increase the working area of the impact.

The third technical result provided by the claimed technical solution is to provide the possibility of creating a magnetic field with a variable component that is relatively small compared to its constant component, which leads to increased efficiency. The practical expediency of using a magnetic field with the indicated ratio of its constant and variable components has been established experimentally.

These technical results are achieved due to the fact that the physiotherapeutic apparatus of electromagnetic exposure contains an inductor and a permanent magnet, the magnetic axis of which coincide when passing through the winding of the inductor of an electric current, and technical means for controlling the operation of the inductor. Moreover, the apparatus further comprises one or more such pairs of magnetic field sources, between which additional permanent magnets are placed, oriented in the working direction by poles opposite to the poles of permanent magnets in pairs, and technical means for controlling the operation of more than one inductance coil, configured to supply to adjacent inductance coils of electrical pulses in antiphase. Moreover, the resulting resulting magnetic field is characterized by induction with a constant component of 20-100 mT, a variable component of 1-10 mT, a change in the magnitude of the induction by no more than 1/3 of the value of the induction of its constant component, and

change frequency of 8 Hz.

In the particular case of the apparatus, all or part of the pairs of emitters are an inductor placed above the permanent magnet or an inductor with a core in the form of a rod of ferromagnetic material mounted on a permanent magnet, or an inductor with a core in the form of a rod permanent magnet. In a particular case, inductors are solenoids.

In another particular case of the apparatus, the permanent magnets are placed on a common base of magnetically conductive material.

In another particular case of the apparatus, the pairs of emitters are arranged linearly and in rows.

The technical solution is illustrated by the following figures:

- figure 1. Schematic representation of the layout of the magnetic system;

- figure 2. Schematic diagram of the device;

- figure 3. Image of the signal applied to the solenoid;

- figure 4. The algorithm of the device.

The physiotherapeutic device of electromagnetic influence "Homeoton" is structurally made and works as follows.

Permanent magnets 2, 3 and 4 are fixed on a common base 1 (see Fig. 1A) made of a magnetically conductive material, oriented with one of its poles in the working direction, perpendicular to the base 1. These magnets are located on the base in series, along one line, although a possible embodiment of the device, in which the magnets are located in more than one row.

On top of magnets 2 and 4, solenoids 5 and 6 are installed, having cores of ferromagnetic material. On top of the magnet 3 is also installed rod 7 made of ferromagnetic material. The height of the rod 7 corresponds to the height of the solenoids 5 and 6. Magnet 2 and solenoid 5 form the first pair of emitters, and magnet 4 and solenoid 6 form the second pair. Thus, each pair of emitters contains a source of a constant magnetic field, in the form of magnets 2 and 4, as well as a source of an alternating magnetic field, the function of which is performed by solenoids 5 and 6 when an electric current is passed through them, as a result of supplying pulses of data solenoids

electrical voltage.

Since in each pair the magnet and the solenoid are mounted coaxially and the magnetic axes of the emitters coincide, this makes it possible to emit magnetic fields along one axis common to them. Thus, it is possible to obtain the resulting magnetic field, characterized by the constancy, within the specified limits, of the direction of the magnetic induction vector at each point of the working area of the action in time, which was not performed when the solenoids and the permanent magnet are not coaxially arranged, as shown in Fig. 1B (one previously known arrangements).

The findings of the windings of the solenoids included in the magnetic unit 8 are electrically connected to the power unit 9 through a microcontroller 10, electrically connected by its respective inputs / outputs to the controls and indicators 11 (see figure 2).

It should be noted that the source of a constant magnetic field may have other options for its implementation, for example in the form of an electromagnet. In this case, the microcontroller 10 must provide control over the operation of all inductors.

The functions and operating modes of the microcontroller 10, controls and indicators 11 in the apparatus according to the present technical solution make it possible to use the element base customary in the art for the implementation of these blocks. In particular, almost all the basic functionality of the device is implemented through the Atmel Corp.’s ATmega88 microcontroller.

The main element of the power supply is preferably suitable electric batteries or accumulators, allowing the portability of the device.

When the device is put into operation with the specified exposure parameters, by means of appropriate controls, for example, buttons or switches, the microcontroller with the appropriate software generates a control signal for applying a positive polarity pulse to the first solenoid 5. At the same time, the same pulse is applied to the winding of the adjacent solenoid 6, but having a negative polarity (see Fig. 3). Therefore, the emitters are ac

magnetic fields included in neighboring groups work in antiphase. If the device contains many pairs of emitters, then the same voltage pulses are applied to the solenoids through one or in a checkerboard pattern.

Such inclusion of solenoids leads to the fact that the resulting magnetic field is characterized at a given point in time by the presence of at least one region with a maximum value of induction and at least one region with a minimum value of induction. Moreover, the spatial arrangement of these areas of maximum and minimum induction correspond to neighboring groups of emitters operating in antiphase. It has been experimentally established that such a spatial configuration of the magnetic field leads to a decrease in the spread of excitation of the peripheral nervous system outside the area of influence.

To increase the effective volume of the working area of influence, the composition of the emitters of the magnetic exposure unit 8 includes a permanent magnet 3 or magnets, with the number of pairs of the previously mentioned emitters more than one, located in the same way, that is, between such pairs of emitters. The passage of the magnetic field lines in the absence of magnet 3 is shown in Figure 1 B. This figure shows that the space of the working area of influence between the pairs of emitters is characterized by a low density of field lines due to the fact that the field lines tend to close to the opposite pole of the magnet of the same couples.

However, with the introduction of an additional magnet 3, the picture changes. In the space of the working area of influence, the density of the field lines increases due to the extension of the magnetic field between the pairs of emitters.

Obtaining the required parameters of the resulting magnetic field is carried out according to the algorithms of the software of the microcontroller 10 and does not cause technical difficulties when implemented by means known from the prior art. Within the framework of this technical solution, it is recognized that it is most expedient to use a magnetic field, the induction of which changes by no more than 1/3 of the value of the induction of its constant component and characterized by induction with a constant component of 20-100 mT,

variable component of 1-10 mT and a frequency of change of 8 Hz. The indicated characteristics of the magnetic field made it possible to achieve the maximum therapeutic effect.

The physiotherapeutic device of electromagnetic influence "Homeoton" also allows you to provide a therapeutic effect by means of an electric periodic non-harmonic signal of rectangular shape with a duty cycle of 2 with an automatically selected frequency (see figure 4) in the range of 5-100 kHz, preferably 28-35 kHz, taken from the electrodes . The full amplitude of the acting pulse is 10 V.

Before a session of physiotherapeutic exposure to electric current, an automatic selection of the frequency of exposure is carried out on the basis of scanning with a given step of a certain frequency range. In this case, an automatic measurement of the electrical conductivity parameters of the human body area at the scanned frequencies is performed, after which the frequency is selected as the maximum, minimum, average or other calculated value. In addition to the frequency, it is possible to select the amplitude or other parameters of the alternating current.

Such a choice of parameters of exposure signals before the session is a biologically feedback and can improve the effectiveness of therapy and reduce the side effects of electrotherapeutic procedures.

For scanning using two or more electrodes located on the surface of the body. The exposure is carried out through the same electrodes, immediately after the specified scanning procedure.

The device is made in the form of a compact, portable device.
