Description

 The invention relates to medical equipment and is intended for use in physiotherapy as a radiator for the treatment of inflammatory processes, in particular, in dentistry, neurology and traumatology.

 At present, low-frequency magnetotherapeutic devices, for example, the Inductor series apparatus, the Alimp -1 apparatus, the MAG-30 apparatus, etc., are widely used in medical practice [1]. The devices are intended for the treatment of inflammatory diseases in various fields of medicine. The devices contain an electromagnetic wave generator and an inductive emitter with a ferromagnetic core, designed for local (local) exposure. The treatment effect is usually achieved by affecting the pathological focus or on the areas responsible for the processes occurring in the pathological focus. This provides minimal contraindications and the absence of harmful side defects [2].

 However, the known devices are low-frequency and in the treatment of high-power signals are used. Scientific studies in a number of countries have shown that a therapeutic effect can be obtained by using a high-frequency amplitude-modulated low-power sinusoidal signal [3,4]. Good results were obtained when apparatus was used for physiotherapy using signals with a carrier frequency in the range of 100-1000 kHz, amplitude-modulated by signals in the range of 10-1000 Hz.

 For these devices, resonant emitters designed in the form of a resonant oscillatory circuit containing an inductor and a capacitor are developed. Using a resonant emitter allows you to get a great therapeutic effect with a low power source of electromagnetic energy.

 The closest in technical essence is a resonant emitter used in a multi-channel rheograph [5].

 The emitter contains an inductor with a coupling winding, placed on a dielectric frame, which is made in the form of a cylinder.

 However, the known emitter has limited experimental capabilities. A resonant emitter is required for dentistry, neurology and traumatology.

 The objective of the invention is the expansion of operational capabilities.

 This is achieved by the fact that a resonant emitter containing an inductor, which has a main winding and a coupling winding, a capacitor whose terminals are connected to the terminals of the main winding, a ferrite core, a casing and a base with a coaxial input of electromagnetic energy fixed to it, in which the contacts connected to the terminals of the communication winding, according to the subject invention, the main winding and the communication winding are made in the form of two semi-windings connected in series and according to, each of the semi-windings o novnoy winding and winding connection placed on a separate insulating frame prescribed in the cup armor ferrite core, both cups fixed to the base with a gap equal to (0.2-0.3) D, where D - outside diameter of the cup armored core.

 The essence of the invention lies in the fact that the resonant emitter contains two cups of an armored core mounted on a dielectric base and installed with a gap, a dielectric frame is fixed in each cup, on which a half-winding of the main winding and a half-winding of the communication winding are placed. Half-windings are connected in series and in accordance. The main winding with a capacitor form a resonant oscillatory circuit. Ferrite cups partially shield the electromagnetic field of the emitter from a non-working surface.

 In the upper part of the emitter there is an external electromagnetic field due to the mutual induction between the semi-windings of the main winding.

 In FIG. 1, 2 shows the proposed resonant emitter (in section); in FIG. 3 shows the electrical connection diagram of the windings. The proposed resonant emitter contains a base 1 made of a solid dielectric. Cups of an armored ferrite core 2 and 3 are installed in the base nests, in which dielectric frames 4 and 5 are fixed with glue. The height of the frames is 2 N, where - N is the internal depth of the cup. On each of the frames there are half-windings of the loop winding 6 and 7 and half-windings of the coupling winding 8 and 9. Half-windings of the loop winding 6 and 7 are connected in series and according to. The terminals of the loop winding are connected to the terminals of the capacitor 10. The terminals of the coupling winding are connected to the contacts of the coaxial energy input 11, which is fixed on the base 1. Rod ferrite cores 12 and 13 are glued to the middle of both cups, the height of each is N. The emitter is closed by a solid casing 14 of solid dielectric, which is made of a material used in medical technology. The outer surface of the casing is working.

 In the proposed emitter, ferrite cores are used from material of the brand M - 700 NM or from material of the brand M 1500 NM. For the contour winding, a wire of the LEPKO 16x0.07 brand is used. The coupling winding can be made with a PEV 2-0.25 wire. The proposed emitter operates as follows. Using a cable from the generator of high-frequency signals, a signal is supplied to the communication winding with a frequency equal to the resonant frequency of the loop winding, which is determined by the inductance of the two half-windings and the capacitance of the capacitor. At the emitter, an external electromagnetic field is formed from the side of the casing’s working surface. For treatment, the emitter is placed on the patient's body.

 The emitter was tested experimentally in various clinics in Omsk. Tests have confirmed high efficiency.
