Description

 The invention relates to devices for the prevention and treatment of diseases of biological objects by non-contact exposure to areas of biological objects with electromagnetic radiation of ultra-low intensity and can be widely used in medicine, veterinary medicine, biology and agriculture.

 Known domestic and foreign devices for wave therapy, which contain, as a rule, a power supply, a source of high-frequency oscillations, as well as an emitter (see, for example, AS USSR N 939021, 940387, AS Japan N 60-57350 , the Federal Republic of Germany N 3534213, the journal "Electronic Industry", 1987, issue 1 (159), pp. 30-35, etc.). Known devices have significant dimensions and weight and are used for therapeutic effects in stationary conditions of medical institutions.

 In domestic practice, devices for microwave therapy of the EHF Electronics series (EHF - extremely high frequencies) are used, as described in the journal Electronic Industry, 1987, no. 1 (159), pp. 30-31. These devices consist of two main units: a generator chamber with a working head (emitter) and a power supply, regulation and control unit located on a rack, the lower end of which is mounted on a massive base, and the mechanism for moving the generator chamber in vertical and horizontal directions, with the possibility of rotation for orientation and fixation of the emitter relative to the reflexogenic zone of a biological object. To expand the functionality of the device in its design, it is possible to install interchangeable units, which are used as a reactive-reflecting resonator or a mechanism for smooth mechanical tuning of the frequency of electromagnetic radiation in a narrow frequency band, or an electrically controlled element that implements smooth electronic tuning in a wider frequency band. This is necessary due to the fact that, according to existing medical methods, the effectiveness of exposure for almost every reflexogenic zone for each biological object is achieved at a frequency specific for this point and for this organism, or rather in a rather narrow range of frequencies that are selected from the range of so-called therapeutic frequencies lying in the range of 40-300 GHz.

 Such devices, in view of their considerable size and mass, are effective for therapeutic effects in stationary conditions of medical institutions and it is quite clear that patients resort to their effects, mainly already at the stage of the developed disease.

 In accordance with the sanitary standards of Ukraine, the levels of electric and magnetic fields in the range up to 300 MHz and energy flux densities in the range above 300 MHz are standardized. In this application, we are talking about the intensity and power flow, which is several orders of magnitude (1-5) below the maximum allowable for round-the-clock exposure.

 Currently, the most popular means to prevent possible diseases or to correct the functional deviations of the body at the initial stage of the disease. For these purposes, portable equipment implemented on the basis of modern microelectronics, convenient to use in domestic or mobile conditions, is necessary.

 Known medical device (see, for example, the application of France N 2541902, MKI - A 61 N 5/02), containing a power supply unit, a frequency generation unit stabilized by quartz, a modulator, a unit for a controlled pulse generator, to which are connected the control units for duration, frequency and pulse amplitudes, while through the pre-amplification unit, a power amplifier and a bandpass filter, the modulator is connected to the emitter.

 However, if the devices of the "EHF Electronics" series have a replaceable unit for frequency tuning depending on the zone of influence chosen by the doctor, then this device containing the oscillator stage, stabilized by quartz, works only at a fixed frequency, which significantly reduces its functionality. It should also be noted that all of the above devices, in the process of influencing the reflexogenic zone, operate at a fixed frequency selected for this zone, due to the design of the generator unit. It is known that for any living organism there is a concept of the so-called "addiction effect" to a uniform irritating effect even for a short period of time. In this regard, it can be assumed that the therapeutic effect of exposure to electromagnetic radiation at a fixed frequency decreases by the end of one treatment procedure and / or correction of the functional state of a living biological object.

 The closest technical solution to the claimed is a device for microwave reflexology "Threshold" (see, for example, the journal "Electronics", 1987, issue 1 (159) p. 30, author SP Sitko and ND Kolbun , author certificate SU N1611345 A1, class MKI - A 61 N 5/02), containing a power supply unit connected in series with a cascade of pulse voltage generation, the output of which is electrically connected to a pulse generator of EHF noise, which through a high-pass filter and a wave type transformer connected in series with it is connected to the antenna a radiator.

The main disadvantage of the Threshold device is that the authors' claims about the frequency spectrum of EHF noise, including its total intensity in the range 30-300 GHz, are not confirmed experimentally by metrologically certified means, but are based only on general reasoning. Experimental verification of several instances of the Threshold device by independent experts using ultra-sensitive radiometers calibrated according to standard methods with noise sources (noise lamps GSh5, GSh6, where P ₀ = 60 kTo, see D. S. Gurlev, reference book on ionic devices, Kiev, 1970, p. 176), the threshold sensitivity of which reached T _pores. = 0.1K, at frequencies of 40, 60 and 100 GHz, it did not confirm the presence of signals in the Threshold device above the threshold level. However, in these devices, relatively high levels of low-frequency noise are experimentally established, which was not discussed in the description of the invention.

 The objective of the invention is to provide a device for information-wave therapy "IVT-Threshold" with minimal weight and size characteristics while improving the therapeutic effect on a biological object and expanding functionality by using modulated oscillations, the energy spectrum of which S (f) is described by a power dependence of the noise flicker type "S (f) = S (o) f, which plays an important role in activating the body's defenses, regulating and controlling physiological processes in biological systems (see, M.S. Keschner. Noise like l / f TIIER, vol. 7, N 2, 1982, pp. 60-66; S.M. Rytov. Introduction to statistical radiophysics, 1966, pp. 231- 235).

 The problem is solved by the claimed device for information-wave therapy "IVT-Threshold", containing a power supply, a generator connected to a band-pass filter and an antenna-emitter, while a distinctive feature of the claimed device that allows to solve the problem is that the generator is made in the form a blocking generator assembled according to a circuit with transformer coupling at a frequency of f = 50 kHz and a pulse duration of T = 0.1 μs, which is connected through a matching transformer to a pulse detector and capacitive a drive, connected to a non-linear block - a pulse discharger, in the charge circuit of which a variable resistor is installed - a pulse repetition frequency regulator, and a pulse boost transformer is installed in the discharge circuit of the capacitors, connected to a concentrator and an antenna-emitter of electromagnetic waves, while the active plane of the emitter is proportional with the plane of the active zone of the skin surface of the patient, and the emitter in its lower part is made in the form of a cone.

 The claimed invention has novelty, since the applicant has not found sources of fame for an identical solution.

 The claimed invention possesses an inventive step since an unexpected positive therapeutic effect was obtained as a result of the experimental verification, and the listed disadvantages of the known devices were eliminated in the information-wave therapy device "IVT-Threshold".

 The invention is illustrated in the drawing, which schematically shows a combined circuit of the inventive device "IVT-Threshold".

 The device for information-wave therapy "IVT-Threshold" (see the attached combined circuit) contains a power supply 1 and a generator unit 2, made in the form of a blocking generator with transformer coupling, connected by a matching unit 3 through a 4 pulse detector of positive polarity with a capacitive storage 5 energy. The blocking generator 2 performs the function of a master oscillator, and the matching unit 3 can be made in the form of a matching step-up transformer. A regulator 6 of the pulse repetition rate is installed in the charge circuit of the capacitive storage 5, and the capacitive storage 5 is connected to the emitter 9, made in the form of a bandpass filter, through the pulse discharger 7 and an additional matching unit 8, the active plane of radiation of which is proportional to the plane of the active zone of the patient’s skin surface .

 Device for information-wave therapy "IVT-Threshold" works as follows.

 The supply voltage from the power supply unit 1 is supplied to the generator unit 2, which generates short pulses (t = 0.1 μs) with a pulse generation frequency of 50 = 3 kHz and is assembled according to a transformer coupled circuit. The generated pulses through the matching unit 3 in the form of a step-up transformer are fed to the detector 4 pulses of positive polarity, which by detecting converts the pulses into direct current and charges the capacitive storage 5. In this case, the capacitive storage 5 after the charge is discharged on a pulse discharger 7, and the pulse repetition rate set by controller 6. Moreover, the discharge passes through an additional block 8 matching, which can also be made in the form of a boost matching transformer. When the capacitive storage 5 is charged to a predetermined threshold voltage, a breakdown of the pulse discharger 7 occurs, as a result of which a current pulse arises in the winding of the step-up matching transformer, additional matching unit 8, which generates an oscillating broadband voltage pulse in the other winding. This voltage is supplied to the emitter 9, made in the form of a broadband filter, in which the upper cut-off frequency is determined by the distance between the emitter and the active zone of the patient’s skin surface, and the lower one is determined by the geometrical dimensions and the shape of the emitter, which is conical in its lower part, which allows increasing tension E-component fields and energy flux density in the area of influence on the core.
