Description

The invention relates to medical equipment and can be used in physiotherapy.

Known magnetic therapy devices with the creation of permanent magnetic fields (PMF) and the generation of intense pulsed magnetic fields (IMP), used in physiotherapy, as a rule, separately, according to published data, for example: G.N. Ponomarenko / Physical methods of treatment / St. Petersburg, 1999, - 252 p.

As a prototype, the apparatus for treatment with a pulsed magnetic field "ALIMP-I", described in the reference book: Magnetic therapy equipment / Ed. G.R.Solovieva / M., 1991, - 127 p. The disadvantages of devices of this type include their relatively large dimensions with a mass of about 30 kg, the presence of wires between the pulsed magnetic field generator and the power and control unit, which make their operation difficult.

The aim of the invention is to expand the capabilities of physiotherapy apparatus while using constant and pulsed magnetic fields, reducing dimensions and improving performance through the use of miniature and autonomous apparatus.

The invention is illustrated by the description below and with the help of Figure 1, which shows the design features of the proposed apparatus of magnetic therapy, and Figure 2, which shows the electron diffraction pattern of the patient's fingers before and after the session of magnetic therapy. On figa and 1B shows the lateral and frontal section of the apparatus MT "Creole-I1", where 1 is the apparatus body, 2 is the power supply (two AAA batteries), 3 is the control system, 4 is the generator of an intense pulsed magnetic field, 5 - an outer ring magnetic core made of soft magnetic material, 6-7-8 - a system of coils with current, made in the form of prismatic cones in number from 4 to 24 pieces and tightly spaced radially and concentrically inside the magnetic core, 9 - prism made of hard magnetic material, 10 - biosystem . On figa and b shows photographs of the halo of the fingers before and after MT.

An example of a pulsed magnetic field generator. The total number of conical coils is 5, - four coils are located inside the annular magnetic circuit radially, tapering part to the center, the fifth is located in the center. In the electric circuit, all five coils are connected in parallel, which helps to increase the speed of growth of the magnitude of the magnetic field pulse (the rise and fall times of the current pulse and, accordingly, the magnetic field pulse are reduced). Inside the annular magnetic circuit, after the location of four coils, four voids are provided, which are filled with four prisms of hard magnetic material, necessary to create a constant magnetic field of the order of 1-10 mT. When a pulse voltage is applied to 40 V coils, a pulse current of the order of 3 A is generated in them and a pulsed magnetic field of 100 mT (± 3 mT) of 2 μs duration is generated in the working area. With an increase in the number of coils to 24, UTI increases to 150 mT.

Pulsed magnetic fields of the most diverse configurations are widely used in magnetotherapy for accelerated healing of wounds, fractures and bone tissue. When interacting with magnetic field pulses, microvibrations and microconvection occur due to magnetohydrodynamic forces in the volume of biological tissue. This leads to an increase in the rate of metabolic processes, a change in the permeability of cells, and the rate of delivery of reagents to functioning membrane surfaces and informational macromolecules.

The processes developing on biomembranes turn out to be triggering for excitable structures, among which the most sensitive are the elements of the neuroendocrine system that determine the integration of the response at the systemic and organ levels. Moreover, the biological effect is exerted on almost all body systems: nervous, endocrine, immune, cardiovascular, hematopoietic, metabolic processes, etc.

We note a very important circumstance of the effectiveness of the impact of a pulsed magnetic field with a relatively low magnetic induction intensity of 75-150 mT, but with high growth rates of magnetic induction and subsequent decay. In other words, magnetic pulses with steep edges of the order of 0.5 μs, which is the value for the dynamic parameter of the magnetic pulse dB / dt = 1-2 10 ⁵ T / s. In existing devices with pulsed magnetic fields up to 1.2 T, the dynamic parameter is significantly less: dB / dt = 10 ³ T / s. Thus, from the point of view of the dynamic characteristics of pulsed magnetic fields, our Creole-I1 apparatus achieves high efficiency at low energy consumption, which allowed us to create a small, lightweight, stand-alone device.

An example of working with the apparatus MT "Creole-I1"

Technical characteristics of the device “Creole-I1”

The working surface of the apparatus is treated with 70% alcohol.

The device is easily sealed with a plastic bag. This feature (disposable tool mode) is important when working in the field, which requires only a supply of small plastic bags.

Working methods. Developed at the Educational and Scientific Medical Center of the Presidential Administration of the Russian Federation.

Work with the apparatus "Creole-I1" was carried out in several ways. Contact method: the device is installed on the exposure zone indicated on the corresponding diagram, contact through one layer of plastic film, 1 layer of gauze, a shirt, dress with moderate pressure (compression) on soft tissues.

Distant technique: the device is installed at a distance of 3-5 mm above the impact zone.

Stable method of exposure: the apparatus is installed on the exposure zone and does not move during the entire exposure time.

The labile method of exposure can be used both with distant and contact methods (without compression of soft tissues): the device slowly moves over the area of influence in order to process the entire area.

Clinical trials of the Creole-I1 apparatus, conducted by us, showed its effect on the systemic energy of the body, in particular on the number and dynamics of free electrons in the tissues of the body (photographing fingers using the Kirlian method). Figure 2 shows photographs of Kirlian in a 24-year-old patient suffering from post-traumatic osteochondrosis of the thoracic spine. Prior to the procedure, the view in Fig. 2A, while a pronounced pain syndrome was noted. After the procedure (UTI + PMP 50 mT, exposure to two fields in the Th (v) -Th (v11) region for 2 min each), the view in Fig. 2B and the pains practically disappeared (magnetostimulation effect).

For practitioners, the most attention is given to anti-inflammatory, antispasmodic, analgesic, hypotensive, hypocoagulation, stimulating the regeneration of injured tissues and other therapeutic effects of pulsed and permanent magnetic fields used in combination.

Magnetotherapy can be a monomethod of treatment when other methods are ineffective or contraindicated, for example, with allergic complications from medical forms of treatment.

Let us analyze the technical characteristics of the Creole-I1 apparatus. The pulse frequency is set in the range of 80-3000 Hz. The body, as a whole, is characterized by low frequencies of functioning, its regulatory systems - higher, sequentially: 160, 300, 600, 1500, 3000 in the form of a geometric progression, according to the data given in the Collection:

Low-intensity laser therapy / M., "Technique", 2000, 724 p. The frequency of 80 Hz, providing maximum output into the blood of the antistress neuropeptide β-endorphin and growth hormone, reduces pain and restores the modulating effect of the central regulatory centers of the brain on regenerative processes in wounds.

The constant field is set by 4-12 prisms from hard magnetic material, for example, from intermetallic alloys of the neodymium-iron-boron type with high magnetic energy, developed production technology and great stability over time: up to 10 years. Prisms are located on the inner surface of an annular magnetic circuit made of soft magnetic material, for example, from Art.10. The lower limit of magnetic induction of 1 mT is chosen to reliably exceed the PMF over magnetic noise generated by network noise, electric transport, especially inside electric trains, etc. The upper limit of the magnetic induction of the PMF apparatus of 10 mT is selected as the initial values of biostimulation and magnetotherapy. To increase the magnetic induction to 25-75 mT, magnetic nozzles are provided located on the outside of the apparatus, which are fixed coaxially to the IMP pulsed magnetic field generator due to magnetic attraction.
