This invention relates to Medgashna Tt3XHHKe used for magnetic field treatment.

It is known a device for magnetic therapy, containing two magnetic cores connected at one end of a sharvirvo, and having solenoid kitushki, forming a magnetic field G 3

However, the device cannot accurately repeat the shape of the irradiated part of the body, as a result of which a large air gap is formed between the tips, which leads to significant overhead power, and the known device does not provide treatment if there is an external compression and distraction apparatus on the limb,

A well known magnetotherapy device containing a core with a solenoid coil and magnetic cores 2}

However, the operation of such a device requires large power consumption.

The purpose of the invention is to reduce the absorbed power.

In order to achieve the set, they sang in an inductor for magnetic therapy, containing a core with a solenoid coil and magnetic cores, the magnetic cores consist of a series of hinged sections, and the axes of the hinges are flexible.

FIG. 1-3 depicts an inductor in a rectangular projection; in fig. 4 constructive embodiment of the complete magnetic cores; in fig. 5: section A-A in FIG. 2; in fig. 6 and 7 of the position of the magnetic circuit during the comparative tests; on fsg. eight; treatment of the limb with an inducer immobilized by the Ilizarov apparatus; in fig. 9 shows the possibility of changing the shape of the magnetic cores in the plane during the treatment of a part of the body of a complex shape.

The inductor consists of a central core 1, on which the liner 2 is wound. The core 1 is nafan from separate bands of ferromagnetic material, thus assembled, each odd plate protrudes more than adjacent to the even-numbered plate. On both sides, the core sections are hingedly attached to the core 1. Each section is also made up of individual strips of the same ferromagnetic material as core 1. At the ends of the strips forming core 1 and each section 3 of the magnetic wires, there are holes. The plates forming section 3 are inserted into the interstices between the plates of the core 1, intersecting each other in their joints. In this case, the holes at the ends of the plates of the core 1 and section 3 of the magnetic cores coincide, forming a single channel 4 passing through the entire set. A similar connection is also formed at the junction points of the individual sections 3 of the magnetic cores. Flexible axles 5, made, for example, from Bowden springs or flexible cable sections with thickening 6 at the ends, are drawn into channels 4.

The inductor works as follows.

A part of the body that is subjected to magnetisation is placed between the magnetic cores.

7 and the magnetic cores are reduced in such a way that they tightly embrace the part 7 of the body 7. Then they connect the winding 2 to the current source and, by changing its value, establish the magnetic field strength required for treatment. When irradiating the limb with an immobilized transosseous compression-distraction and yarate (Fig. 8), the magnetic cores are inserted between limb 7 and rods

It is in such a way that the apparatus remains outside the magnetic cores. When irradiated, parts of a body of complex geometric shape (Fig. 9) not only vrashakzt 3-magnetic cores with respect to the axes 5, but also change them, the shape of the set plane so that the individual plates forming the set of segments 3 slide ONE relative to another. Possibility of

This manipulation provides Lodpre Shnivaniya joints of segments 3 and the flexibility of the axes 5.

The proposed inductor has a mini-gap of low air gap and provides savings in power consumption.
