Description

 The invention relates to medical equipment and can be used for magnetotherapy, as well as to study the effect of low-frequency variables, including vortex, magnetic fields on biological objects.

 A device for magnetotherapy (prototype) is known (US Pat. RF 2084247, IPC 6 A 61 N 2/00, publ. 07/20/97 Bul. 20, with a priority of 03/13/1995), containing a power supply to which an inductor is connected, made in the form of a frame with a winding, inside which there is a cavity for placing a biological object, and the inductor coils are telescopically one into the other and kinematically connected with a lifting device. The device provides reliability and repeatability of the results when studying the effect of magnetic fields on biological objects. The device is in a certain sense conformal, since inductors cover a biological object with their cavity. In the device, the magnetic field by moving the inductors can to some extent concentrate on the pathological focus of the biological object.

 The disadvantage of the prototype is that it does not achieve a high degree of conformity - the inductors do not adhere to the surface of the biological object; Another point is that the device does not use vortex magnetic fields, and finally, the effect of fields on the biological object in the installation is integral, not localized with a high degree of specificity according to a given program, taking into account the location of biologically active points and reflexogenic zones on the surface (skin) of the biological object.

 The problem to which the invention is directed is to increase the magnitude of the magnetic field due to the conformity of the inductors to the surface of the biological object, as well as to increase the efficiency of the effect by creating a running and swirling right- and left-sided rotating magnetic field according to the program.

 This is achieved due to the fact that in the created conformal magnetotherapeutic installation containing inductors covering a biological object and a control device connected electrically to inductors, the inductors are made in the form of miniaturized electromagnets with cores fixed in the holes of the plate from magnetically transparent and flexible material, and the device The control is made in the form of a PC with an inductors switching unit.

 In addition, the electromagnets are fixed with a cover made of magnetically transparent elastic material sewn through the thickness of the plate.

 In FIG. 1 shows a General view of the proposed conformal magnetotherapy unit with a matrix of inductors in the form of a vest. Other embodiments of the matrix of inductors shown in figure 2-4: a) conformal to the surface of the legs or arms (figure 2); b) conformal to an arbitrary, locally limited surface of the patient (Fig. 3); C) conformal to the lumbar region of the patient (Fig. 4). Figure 5 presents the design of the matrix of inductors. The design of the miniaturized inductor is shown in FIG. 6. Figure 7 shows a block diagram of a device for controlling an array of inductors.

 In FIG. 1, the matrix of inductors is made in the form of a vest 1, the floors of which are connected by fasteners 2, and patient 3 takes the procedure while standing. The matrix of inductors is connected by a cable 4 through a multi-pin connector 5 to a control device 6 with a PC monitor 7 installed on it.

 Miniaturized inductors 8 (Fig. 5) are placed in the through holes 9 of the plate 10 of magnetically transparent and flexible material based on porous rubber or flexible foam. On the back side 11 of the plate 10, the wiring of the switching of 12 inductors is made with the output to the cable 4. The plate 10 is placed in a cover 13 of a magnetically transparent flexible material such as a dense fabric, and the cover is stitched with nylon thread 14 through the thickness of the plate 10.

 A coil 16 is placed on the core 15 (Fig. 6) of a U-shaped shape, the leads of which 17 are soldered to the output terminals 18, and the entire structure is embedded in a rectangular foam 19, with a thin layer of foam on the front (working) surface 20 of the inductor, and the back surface 21 of the inductor placed terminals 18 for supplying voltage to the coil (winding) 16.

 The wiring of the switching 12 is carried out in accordance with the electric circuit of the matrix of inductors of size M x N shown in Fig. 7, and is technically solved in a single and small-scale production by tracing with insulated conductors with soldering to the terminals 18, and in serial production using flexible printed cables.

 In the matrix of inductors 22 (Fig. 7), the inductors 8 are electrically connected along the power circuit of the electromagnets in N-rows and M-columns; respectively, on N-circuits, the matrix is connected to an N-channel key 23 and on M-circuits to an M-channel key 24. Keys 23 and 24 are connected, respectively, to devices for changing the polarity, intensity, frequency and shape of signals 25 and 26. Last, in turn, they are controlled by a scanning device 27, to which a personal computer 28 with a monitor 7, a program unit 29, a hand drawing unit 30, a BAT and RGZ data block (“acupuncture atlas”) 31 are connected. A dialogue mode of operation is provided by the operator 32.

 As core material, magnetizable magnetic alloys or ferrites are used.

 According to a given program, the group and series switching of the inductors is performed, including with a change in the direction of the current in the windings. This creates the effect of moving the magnetic field, for example, right- and left-side rotation of the total magnetic field. At the same time, magnetic fields with a therapeutic effect should contain constant and variable components, and the latter should have three vector components: axial, radial and tangential, that is, rotational, which is achieved in the proposed installation. In addition, the program adjusts the current frequency of the field change, pulse shape, field intensity, polarization characteristics. The latter is most important, because the polarization (right- and left-handed rotation) characteristics of the generated magnetic field must be consistent with the direction of movement of energies and currents in the corresponding meridians of the human body, having an exit in the form of biologically active points (BAP) and reflexogenic zones (RSE) of Podshibyakin zones and Zakharyin - Hera. And this movement can be centrifugal for some meridians and centripetal for others. Thus, the best option is to rotate the field with a scan in a spiral (right- and left-sided), or “pull” to a point also in a spiral. In the device, this is implemented using the inductor switching program.

 The proposed magnetic system with scanning (sweep) of the vortex magnetic field creates a wide spatio-temporal and spatio-frequency spectrum of magnetic fields, the latter, dynamically changing, at the same time creating broadband streams of highly coherent electromagnetic fields with a large set of energy-frequency and polarization characteristics. Therefore, a bioobject (with its BAP and RSG) has the ability to select from the entire set of magnetic and electromagnetic fields that portion of the spectrum or its specific component that is consistent with the spectral and spatio-temporal characteristics of the bioobject. Here, the fundamental position of biophysics is used that the body perceives only fields that are immanent for the current state of the organism, as well as the fact that only an organism in a pathological state is sensitive to specific fields, and a healthy organism is indifferent to electromagnetic fields in a significant range of frequencies and intensities.

 Comparative analysis shows that the claimed conformal magnetotherapy unit differs from the prototype in that the inductors are made in the form of a matrix of miniaturized electromagnets with cores, conformal to the surface of the bioobject, switched by the PC program, which allows creating a vortex magnetic field with a wide range of its components immanent to the bioobject. Therefore, this technical solution meets the patentability criterion of "novelty."

 The procedure is adopted as follows.

 Depending on the nosology of the disease (or the types of inductor matrices available; see FIGS. 1-4), the procedure is taken in a sitting, standing, lying or other position. The matrix of inductors is installed and fixed on the patient’s body and connected to the control device. The operator, using the guidelines (experience with the installation), selects the desired program for the session and starts it. Monitoring is carried out visually - according to the scheme on the monitor screen. If necessary, the operator turns on the “manual” mode and, controlling his actions on the monitor screen, which also displays the layout of the meridians, BAT and RSH, either adjusts the basic program taking into account the specifics of the disease or personal experience, or, drawing with the “mouse”, draws contours motion of the magnetic field. Thus, the flexibility of using the installation for the treatment of diseases of various nosological forms is achieved.

 The most effective use of the proposed conformal magnetotherapy unit for the prevention of cancer, immunostimulation, correction of immunodeficiency, treatment of cardiovascular, neurological, gynecological, gastroenterological, inflammatory dental and some other diseases.

 The installation is easy to maintain, meets the electrical safety standards of medical equipment (inductors are powered by low voltage), and in the automatic (program) mode of operation does not require special training of the operator. Production of the installation, including software, is possible at any instrument-making enterprise.

 The installation can be used in physiotherapy rooms, medical institutions and for scientific research on the creation of new methods of treatment.
