The unit contains a magnetic inductor with current-carrying frames, forming a rotating magnetic field and correcting the DC component of the magnetic field. The Converter and the power source are combined in a single unit. To the inputs of the source and transducer attached control device, such as a personal computer, to the input of which is connected measuring magnetic induction sensor of the magnetic field in the inductor. The apparatus also contains a bed for the patient.

The invention relates to medicine and medical technology, physical therapy devices, and is intended to accelerate the regression of inflammatory processes, treatment of other diseases, such as musculoskeletal, Oncology, trauma, etc.Known magnetotherapy apparatus copyright swidey, lying in the plane perpendicular to the axis of the cylindrical inductor. The use of the apparatus A. C. 826587 ("Magnitoturbotron") allowed us to obtain positive results in the treatment of breast cancer. However, this device has a number of disadvantages. The rotation of the MP field is abruptly so that the magnetic induction vector has 6 fixed positions instead to make uniform rotation. In addition, pereklyuchanie current in the windings of the inductor, providing rotation of the MP, is performed by means of a mechanical drive with two systems of rubbing contacts. This drive roads, bulky, associated with high power consumption and low reliability, rigidly attached to the magnetic coil. The change of frequency of rotation is not provided, which eliminates the possibility of optimizing the treatment regimen for this important parameter. There is also no data about the homogeneity of the MP in the inductor.Known magnetotherapy unit RF patent N 2033205, class A 61 N 2/02, in which in order to "reduce the weight of the inductor and increasing the homogeneity of the magnetic field in the working volume are used dielectric frame, is hosting a three-phase two-pole within the thickness, defined by the empirical formula, and the ferromagnetic casing. The disadvantages of this setup are the high installation costs, though reduced, but still large enough mass, the lack of job opportunities in the frequency range below 50 Hz (in this range are "Windows" of biological activity, including the frequency of the electrocardiogram and electroencephalogram,  ), psychological discomfort (during the treatment session, the patient is almost in a confined space, because the diameter of the frame is much less than its length), need lots of free space before installing (not less than 2 m) for pull-out from the coil table with a couch for the patient.Similar drawbacks and magnetotherapy unit for RF patent N 2034579, class A 61 N 2/00, 1992. Apparently, it is even more narrow than the previous one, because the input windings of the inductor provided by the capacitors, forming with them a system of resonant circuits.It is also known a device for rotating impact of MP on biological objects by the patent RF N 2039578, class A 61 N 2/00, 1991, adopted as a prototype, in which "to produce a uniform magnetic field, the inductor will the correct n-polygonal prism, covering the biological object, and the scope of the emitter are both secondary windings of the transformers, the primary winding of which is connected to the current source through gazorazdelitel so that adjacent frames is energized with current from the phase shift is 360oC/n degrees. In the claims of the patent 2039578 said: "each frame zapityvat current with a phase shift of 360oC/n (oC - patently false), where n is the number of frames". In accordance with this patent requires twice the number of amplifiers (with phase shift) control n frames than in the proposed device.In the description of the patent 2039578 also States that "to improve the uniformity of the magnetic field in the device extra transformers on opposite sides of the framework, the primary winding of which is connected with the primary windings of the main transformer". The authors of the patent offers a complex system of transformers with ferrite cores, load short-circuited coils, which, in turn, the current framework for the formation of spatially homogeneous MP in the working volume. However, the specific values of the expected field homogeneity dosukoi framework is fundamentally impossible without the use of transformers, the secondary windings of which are mentioned frame. Meanwhile, it is known (see, for example, ) that the ratio of the magnetic induction B to the amplitude of current I in the windings (the framework) is on systems that use ferromagnetic materials is a complicated nonlinear function of current and frequency
B/I = f(I) (1)
Such systems are characterized by the appearance of higher harmonics of current and hysteresis phenomena. All this complicates the control system of the apparatus. In the absence of ferromagnets
f(I) = const, (2)
i.e., B is proportional to I at any frequency and higher harmonic and hysteresis phenomena are absent. But all 4 are considered inventions (including the prototype) using one or the other ferromagnetic parts that, as follows from the above, is a common drawback of these inventions.The disadvantage of these inventions (including the prototype) is the lack of opportunities to create in the working volume of the inductor at the same time variable (rotating) and a constant magnetic field.The technical result of the invention is to reduce weight, simplify and cheapen the manufacture and operation of the apparatus, increasing the compactness of its placement, the creation of proviantom, creating the possibility of a simultaneous total magnetic field and local impact, for example, laser light or generator EHF. The invention also enables the creation and management of permanent MP in the inductor with a rotating MP and improve field homogeneity in the working volume.The technical result is achieved by the fact that magnetotherapy apparatus, includes a current source, current transducer, a bed for the patient and the magnetic inductor, made in the form of conductive framework to limit the working volume, and connected to the corresponding outputs of the drive current for forming a rotating magnetic field. The apparatus also includes a control device, measuring a magnetic field with a magnetic field sensor and the inductor, including supporting, fixing and insulating elements of the dielectric materials. The conductive frame of the inductor is made of metal with a magnetic permeability equal to one, and a pair of frames arranged symmetrically about the longitudinal axis of the inductor, electrically United to the modules. The output of magnetic field meter is connected to the input of the control device, and its outputs connected to the input is. According to the invention, the number m is placed around a common axis of symmetry of the modules in the inductor is at least two, and the size and position of the bed for the patient associated with the size of module expressions L/H = 1 + 21/2A/H and D/A < 1, where L is the length of the modulus, A is the width of the frame and the distance between frames, H is the length of the bed for the patient, D is the width of the bed for the patient.The essential feature of the invention in a two-module embodiment of the inductor when m = 2 is the fulfillment of the bed for the patient movable in the direction perpendicular to the longitudinal axis of the inductor. According to the invention, the inductor includes additional modules, and the power source includes an additional constant current source, the outputs of which are connected to the frame extensions. The essential features are the implementation of the current source, providing the opportunity for independent adjustment of DC component, and rectangular framework modules that represent single-layer helical winding. When m 3 transverse side frames are of arcuate form.Another significant feature of the invention is the presence of the control device, allowing you to simultaneously change the sign of the phase shift of the currents on bhagnani induction. So, if, for example, when a phase shift of the currents (conditionally with a plus sign) rotation of this vector is clockwise, then by changing the minus sign on the rotation will be counterclockwise.It is known  that the magnetic field, the magnetic induction vector which rotates uniformly, without changing in size, is called circular. The amplitude of the current is also constant. When inequality currents in the modules is created instead of a circular rotating elliptical field, the resulting induction vector which describes an ellipse and has a variable angular velocity. Introduction to the control circuit of the apparatus of the element separate adjustment of the currents in the modules is also an essential element of the invention.It is known that at any point on the earth's surface there is a constant MP, the magnitude of the magnetic induction depends on the geographical coordinates of the point. Near magnetic anomaly value can't take a particularly high values. In addition to the geomagnetic component near industrial enterprises, the accumulation of significant quantities of ferromagnetic materials, in buildings of reinforced concrete, etc., can be man-made composition is on the effectiveness of magnetic therapy and cause ambiguity results of its use on the devices, located in various places .A new direction of work on the application of MP are studies of the metabolism of the cells in the ion cyclotron resonance (see, for example, [1, 4] ). The intended result of these studies is the development of medical techniques, based on the effect of ion cyclotron resonance.The presence of the device additional sources of DC and additional modules inductor is an essential characteristic and creates the possibility of regulating the magnitude and direction of vector constant MP. A possible option for achieving this purpose is to feed in the basic modules AC power with independently adjustable constant component, using the known technical means, for example, filters, low and high frequencies  . The apparatus according to the invention creates an adjustable constant MP in the working volume of the inductor, allows, in particular, to carry out compensation of the background field regardless of its origin, while also improving the repeatability of magnetic therapy, but also creates the possibility of conducting studies of ion cyclotron resonance in biology and medicine.In Fig. 1 , what about the additional frame in Fig. 3. Fig.4 is a schematic representation of a two module variants of the inductor, and Fig.3-section two-inductor, made in the form of farm dielectric tubes. Fig.6 - the top 2 options inductor. In Fig.7 is a schematic illustration of the two-inductor with a patient, and Fig. 8 is a schematic representation of the magnetic inductor with m = 2 and an add-on module for changing the magnitude of the axial component of the standing MP. In Fig. 9 is a diagram of the layout of the modules of a three-module inductor.The device includes a constant current source 1 and the inverter power 2, combined into a single unit 3. The output cables of this unit is connected to the magnetic coil 4. The sensor 5 of the magnetic field is connected to the meter 6 magnetic field; measuring device 6 is connected to the control device 7. The latter is attached to the unit current sources 3.In Fig. 2 shows a module consisting of two elongated along its axis rectangular frames 8 and 9, each of which has a gap 10 and 11 for connection to a source of current; the axis of the module 12. The width of the frame A is equal to the distance between frames, whose length L greater than the width A. Small arrows indicate the direction of the currents in the framework, and the view of the module along the axis on the right.In Fig. 3 - option module, which along with the main frames 8 and 9 are additional frames 13 and 14. In the main part of the proceeds of an alternating current I = I0cos t , and the additional constant current I = Ip. In Fig.3 also presents a view of the module along the axis on the right.In Fig. 4 schematically depicts a two-module m = 2 variant of the inductor. One of the modules 15 contains a horizontally positioned frame, and the other 16 - frame found them at an angle /2. The arrows indicate the directions of the vectors of the magnetic induction field generated by each of the modules (B15and B16). In Fig. 4 also presents a view along the axis to the right, showing the currents in the two modules.Structurally, two-module magnetic inductor according to the invention can be made in the form of farm 2m longitudinal and 4m transverse dielectric tubes, which are stacked current-carrying frame (winding) of the inductor. Longitudinal pipes in this embodiment, the structures are parallel to the axis of the coil at equal distances from it. To accommodate the cross-sections of the framework can be used a single dielectric flange.Performing two-inductor in the form of farm dielectric pipe Povoa, typically, and perpendicular to this axis. In Fig.5 the arrow shows the direction of movement of the patient, which may be, for example, moving bed 18 relative to the fixed table 19. When using the sliding table the value of its move "sideways" is much less than for longitudinal movement. In order to move the patient in the direction perpendicular to the axis of the inductor, it may be necessary to make the distance X between adjacent dielectric tube 20 is large enough, no less, for example 40, see Fig. 5 - section inductor, visible dielectric ( as an example - square) flange 21 and the base 22 for installation.In Fig. 6 schematically presents the top on the inductor with extended bed patient: view adopted in practice, and the only possible other designs inductor his mutual with a bed patient location 23 and views on the proposed design of the inductor 24. Fig. 6 indicates the compactness of the latter.Fig. 7 gives an example schematic of a two-module magnetic inductor according to the invention with the patient 25 in the working volume 17 of the inductor. The inductor obrazovatelno table 19. In Fig. 8 is a schematic depiction of the inductor 26, shown in Fig.7, equipped with an additional module 27 for adjusting the magnitude of the longitudinal component of the standing MP.In Fig.9 presents the layout of the modules of a three-module inductor. In the upper part of Fig.9 modules with flat current-carrying part, the front part 28 which partially overlap the end hole of the inductor, and in the lower part of Fig. 9 - option free from this drawback. As can be seen from the figure, the frame modules are transverse conductors in the form of arcs, tightly lying on a cylindrical surface, and the longitudinal conductors remained straight. Depicts a variation in which the sides of the windings lie partly in two layers 29, and each winding on one side lies at the top, and the other party in the lower layer. The advantage of the latter option is the same size and shape of the windings, reducing the heterogeneity of the field in the inductor near current-carrying conductors and increase its ratio of inner diameter to the outer, i.e., the decrease of the wall thickness of the inductor.Magnetotherapy apparatus operates as follows. Before beginning treatment session using a control device 4 (Fig. 1), which mo is the research Institute of the healing session. Program modes may provide an automatic change of mode options at specific points in time, so that during a single session can subsequently impact of small business in several differing from other modes. Mode refers to the combination of the following parameters: speed MP, for example, any of up to 160 Hz, the amplitude of the magnetic induction, the parameters (frequency, modulation depth, the shape of the modulating signal and so on ) and type (amplitude, frequency) modulation, the direction of rotation of the vector MP, circular or elliptical polarization, the duration of exposure in each mode, the duration of the session, and when working with the application of a constant, MP is the magnitude and direction of the vector of magnetic induction, the duration of the MP.The bed 18 of the patient is moved, for example, in the case of two-inductor in the extreme right (Fig. 5) position, lay the patient on the bed and move it perpendicular to the axis of the inductor direction in the working volume of the last 17; at the end of the treatment session return in the extreme right position. In the case of m 3 bed patient is moved in the usual manner along the axis of the inductor.When enabled, the current transducer 2, to m output amplifiers which are connected m modules of the inductor 4. The current from the outputs of the amplifiers enters the frame (winding) of each module with the corresponding phase shift relative to the previous one (see, for example, ). Feedback inductor 4 with the control device 7 through the sensor 5 and the 6 meter magnetic field. In the case of compensation of the background field or research, requiring the combined MP, at the same time from the constant current source the current is supplied an additional winding or a permanent component in the main windings.1.
