Description

 The invention relates to medical equipment and can be used for magnetotherapy, combined with photodynamic therapy.

A device for magnetotherapy (US Pat. RF 20084247, IPC ⁵ A 61 N 2/00, BI 20, 1997), 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 accommodating bioobjects moreover, the inductor is divided into separate, telescopically entering one into another coil associated with a lifting device.

 A disadvantage of the known device is the insufficient degree of localization of the field on the surface (part) of the biological object, the non-use of rotating magnetic fields and the incompatibility (constructive) with photodynamic therapy.

 A device for photodynamic therapy is known (a portable LED matrix array for phototherapy "Geska-2", passport TU-9444-002-07543077-96, manufactured by GNIPP "NIIPP", Tomsk) containing photodiodes of the infrared range and visible red light, placed in a certain order on the working plane, protected by an optically transparent casing and connected to a power source.

 A disadvantage of the known device is a constant radiation mode (without switching during an irradiation session) and structural incompatibility with magnetotherapy.

 There is also known a device (prototype) for exposure to a constant and rotating (vortex) magnetic fields on a biological object (Zhitnik N.E., Novitski Y. V., Privalov V. N. et al. Vortex magnetic fields in medicine and biology // Bulletin of new medical technologies. - 2000. - T.VII. 1. - S. 46-57.), containing a system of magnets that create a constant and vortex magnetic field, placed on a disk rotated in the right and left directions by an electric motor with an adjustable speed by control devices.

 A disadvantage of the known device is the presence of mechanical moving nodes, the limited rotation speed of the magnetic field, the impossibility of direct contact with a biological object, structural incompatibility with photodynamic therapy.

 The objective of the present invention is to increase the therapeutic effect by creating a combined effect on the patient’s body of a constant magnetic field, a vortex magnetic field with left and right rotation, and a traveling electromagnetic field of the infrared and visible red ranges with right and left directions of rotation of radiation, and the sources of all acting fields conformally adhere to the skin of the patient in the desired area of the body.

Magnetotherapeutic applicator combined with infrared and visible emitters, including a system of magnets that create constant and vortex magnetic fields, as well as a control device, magnets are made in the form of inductors mounted in a flexible dielectric plate made of porous material with an optically transparent cover located radial chains displaced relative to each other by an angle β = 360 ^o // n, where n is the number of chains, and radial chains are installed between the chains of inductors and from alternating infrared photodiodes and visible red light, moreover, the adjacent chains of inductors and photodiodes are offset from each other by an angle α = 180 ^o / n; in each chain, inductors and photodiodes are connected to radial power buses, which are connected to the control device via a patch cable; the power bus of the central electromagnet located in the center of the plate is connected to it, and the control device contains a software switch configured to switch inductors and photodiodes in a given sequence.

 Comparative analysis shows that the claimed magnetotherapeutic applicator combined with infrared and visible emitters differs from the prototype in that the emitter system is conformal to the surface of the biological object, the magnetic field is rotated electrically, a system of switched photodiodes is introduced, and the control device controls the speed and direction rotation, as well as the intensity of the magnetic field. The rotation speed of a magnetic zero is achieved much greater than when using mechanical rotation. Therefore, this technical solution meets the patentability criterion of "novelty."

 In FIG. 1 and 2 depict a General view of the proposed applicator; figure 3 - arrangement in the plane of the applicator chains of inductors and photodiodes.

 The applicator 1 is made in the form of a flexible dielectric plate 2 of a porous, magnetically transparent material, covered with an optically transparent cover 3, for example, of a durable plastic film that transmits infrared and visible (red) radiation. To cover 3 tightly against the surface of the plate 2 when the applicator 1 is bent, vacuum packaging of the plate in the cover is used or the plate with the cover is sewn with threads in places free of installed elements.

 The applicator 1 is fixed to the desired area of the patient’s body using belts 4. In the circular zone 5 in the blind holes of the plate 2, an inductor 6, a chain of radial inductors 7, a chain of alternating infrared photodiodes 8 and a visible red range 9 are installed with adhesive fastening.

Infrared photodiodes with a radiation wavelength of 840-950 nm and a radiation power density of at least 1.5 mW / cm ² and red range photodiodes with a radiation wavelength of 660 ± 15 nm and a radiation power density of at least 0.8 mW / cm ^{2 are used} .

 In each chain, inductors 7 and photodiodes 8, 9 are connected to a two-wire power bus 10, which are assembled into a bundle 11 and routed in a peripheral groove 12, and connected to a patch cable 13, which in turn is connected to a control device (not shown).

 In FIG. Figure 3 shows the arrangement in the plane of the applicator of the chains of inductors 7 and photodiodes 8, 9 (conventional symbols).

 The applicator operates as follows.

 The procedure is taken standing, sitting, lying down - depending on the area of the body exposed to radiation. The applicator 1, made in the form of a flexible dielectric plate 2 of a porous, magnetically transparent material, covered with an optically transparent cover 3, is fastened with the help of straps 4 to the desired area of the patient’s body. The cable 13 using the connector is connected to the control device. The operator sets the session mode on the controls on the control device panel and turns on the applicator.

 The software switch of the control device, in accordance with the operator’s mode of conducting a photophototherapy session, alternately connects radial chains of inductors 7 and chains through the conductive power bus 10, assembled into a bundle 11, traced in the peripheral groove 12 and connected to the patch cable 13) photodiodes 8, 9 located in the circular zone 5, creating the effect of rotating to the right or left of the magnetic field and rotating to the right or left of the electromagnetic (in frac light + red light) of the field, and the direction, rotation speed, intensity of the magnetic field and electromagnetic field are independent of each other and are set by the operator with the controls displayed on the control panel. In the same way, the intensity of the constant magnetic field created by the central inductor 6 is set. After the end of the session, the applicator is disconnected from the control device and removed from the patient.

 The applicator is easy to maintain and does not require special (in technical terms) operator training. The manufacture of the applicator is possible at any instrument-making enterprise.

 The applicator can be used in physiotherapy rooms, wards of medical institutions and for scientific research on the creation of new medical technologies. The applicator can be used to treat diseases of various nosological forms, in which both magnetotherapy and phototherapy are indicated (these diseases are well known to physiotherapists).
