Description

The utility model relates to medicine, namely to reflexology and can be used for diagnosis and treatment in punctured EHF-therapy (extremely high-frequency therapy).

A device is known for registering resonantly active frequencies (see RF Patent No. 2108058 C1, published April 10, 1998, “Device for Researching EHF Objects by Exposure”), which contains a millimeter-wave generator, an operational parameters control unit emitting a generator horn antenna, a radiometer, and a receiver radiometer applicator antenna, unit for registering the experimental parameters of an object, a hollow cylinder, a liner, an object under investigation, a protective electromagnetic screen.

The device operates as follows. The antenna applicator is installed in the cylinder in a position corresponding to a given volume of the investigated object. The liner is placed in the cylinder on the end of the receiving antenna-applicator and is filled with the object of study. Power is supplied to all the radio components of the device. Then millimeter-wave radio waves from the generator, through the radiating horn antenna, are directed to the object under study. A signal is provided from the operational parameters control unit, which allows the generator frequency to be tuned with a step in the range of not more than 0.1 GHz, with an exposure of not more than 5 s, and a power of not more than 10 μW. The signal of the object’s radio response to the action by millimeter radio waves, recorded using the receiving antenna-applicator, is fed to the radiometer and then to the experimental parameter registration unit, and the characteristic resonant radio-wave amplitude-frequency spectrum of the object under study is recorded.

The disadvantage of this device is the complexity, great complexity, low accuracy due to the indirect determination of the resonant frequency by means of measuring the radio response in another long wavelength range.

The prototype of the utility model is a device for determining the optimal value of the therapeutic frequency of the patient with resonant acupuncture EHF therapy (see RF Patent No. 2107486 C1, published March 27, 1998, “A method for determining the optimal value of the therapeutic frequency of the patient with resonant acupuncture EHF therapy and a device for it implementation "), which contains a source of electromagnetic energy (EHF generator), a decoupling device, a waveguide path, an indicator, an emitter.

The prototype works as follows. The electromagnetic radiation source generates EHF oscillations, the frequency of which varies linearly using a sawtooth voltage generator. The EHF signal through the decoupling device, the waveguide path and the emitter acts invasively directly into the BAP (biologically active point). Part of the incident power through the first output of the decoupling device is fed to the input of the indicator. The power reflected from the BAP through the emitter, the waveguide path enters the second input of the decoupling device, which at the same time is the output for the radiated power. The indicator measures the ratio of reflected and incident power.

The disadvantage of the prototype is its low accuracy associated with finding the minimum power value (the signal-to-noise ratio in this case is also minimal). The presence of two receiving elements (incident and reflected electromagnetic radiation) also leads to the presence of additional sources of measurement error and, as a consequence, a decrease in accuracy.

The technical problem to be solved is to increase the accuracy and information content in determining the optimal therapeutic frequency of the patient, simplifying the device.

The technical problem to be solved in the device for determining the optimal value of the therapeutic frequency of the patient with resonant acupuncture EHF therapy, comprising an indicator and a series-connected EHF generator, an isolation device, a waveguide path, an emitter, is achieved by the fact that a non-linear receiver and coefficient meter are connected in series amplitude modulation included between the second output of the decoupling device and the indicator, and the indicator is designed to show dence amplitude modulation coefficient (WAC) of the EHF oscillator frequency and EHF generator is a two-frequency with the possibility of adjustment for both the mean and / or difference frequencies of the output radiation.

On Fig shows a graph of the dependence of the coefficient of amplitude modulation on the center frequency of a two-frequency EHF generator 1.

Each of the blocks in the device for determining the optimal value of the therapeutic frequency of the patient can be implemented according to the standard schemes described in the literature.

All units included in the device have power systems, which are not shown in figure 1.

Figure 2 shows the situation when, in the process of searching for the optimal value of the therapeutic frequency, the average frequency of two-frequency electromagnetic radiation (EMR), with the same amplitudes and a definitely specified difference frequency, is located to the left of the desired therapeutic frequency, which does not correspond to the resonant absorption in the BAP. Figure 3 shows a graph of the envelope of the reflected two-frequency signal, in this situation, with a small coefficient of amplitude modulation.

Figure 4 shows a graph when the average frequency of two-frequency radiation, with the same amplitudes and a predetermined difference frequency, coincides with the resonant absorption frequency in the BAP (the optimal value of the therapeutic frequency of the patient). The envelope of the two-frequency signal reflected in this situation, shown in FIG. 5, has a maximum amplitude modulation coefficient. The value of the average frequency of the two-frequency signal will be the optimal value of the therapeutic frequency.

Figure 6 shows a graph when the average frequency of a two-frequency EMR, with the same amplitudes and a definitely specified difference frequency, is to the right of the optimal value of the therapeutic frequency, which does not correspond to the resonant absorption in the BAP. Fig.7 is a graph of the envelope of the reflected two-frequency signal, in this situation, with a small coefficient of amplitude modulation.

On Fig reflects the dependence of KAM on the average frequency of a two-frequency EMR EHF generator 1, with a specific difference frequency. The same dependence will be recorded on indicator 7, in order to be able to determine the optimal value of the therapeutic frequency from the maximum value of the QAM.

Consider the operation of the device to determine the optimal value of the therapeutic frequency of the patient.

To determine the optimal value of the therapeutic frequency of the patient, find the resonant absorption frequency in the BAP, which is characterized by maximum absorption and is the desired optimal therapeutic frequency. The study in the desired frequency range, possibly with an arbitrary change (linear, step, point, etc.) of the two-frequency electromagnetic radiation in the studied range both in the average and / or difference frequencies. The frequency spacing A from the average frequency of the two-frequency EMR is determined by the specified difference frequency in the EHF generator 1. The EHF generator 1 generates two-frequency electromagnetic radiation of the millimeter wavelength range with the same frequency spacing D from the average frequency and the same amplitudes, which through the first input of the decoupling device 2, the waveguide path 3 and the emitter 4, invasively installed in the selected patient BAP, acts on the BAP. The power reflected from the BAP through the emitter 4, the waveguide path 3 is fed to the second input of the decoupling device 2, which at the same time is the output for the radiated power. From the second output of the decoupling device 2, the reflected EMR goes to the nonlinear receiver 5, where the envelope is removed, and goes to the meter of the amplitude modulation coefficient 6. After measurement, the indicator 7 shows the dependence of the amplitude modulation coefficient on the frequency of the EHF generator 1. By analyzing this dependence, you can determine the optimal value of the therapeutic frequency of the patient, which will correspond to the value of the average frequency of the two-frequency signal of the EHF generator 1, at which the amplitude coefficient the bottom of the modulation of the reflected EMR will be maximum. On Fig presents an example of the dependence of the QAM on the average frequency of a two-frequency EMR EHF generator 1.

Since the resonant absorption of EHF is determined in a narrow frequency band ((10 ^-2 ± 10 ^-4 * F _pez. ), Where F _res. Is the central resonant frequency), then a possible resonant absorption, for example, at F _pez. = 50 GHz will be in the frequency separation range from 5 MHz to 0.5 GHz. Consequently, by setting the difference frequency of EHF oscillator 1, so that frequency spacing Δ is greater than or equal to the resonant absorption band in BAT = Δf (greater absorption frequency range of 0.5 GHz at = F _res. = 50 GHz), whereas the resonant frequency will be determined accurately and clearly.

Compared with the prototype for determining the optimal therapeutic frequency, the proposed device with a two-frequency EHF generator does not require measuring the radiation incident on the BAP, unlike the prototype, which simplifies the device and improves accuracy. Also, in the proposed device, the determination of the therapeutic frequency is performed by recording the maximum QAM value, therefore, the signal / noise ratio is maximum, and in the prototype device registration by the minimum value of SWR, signal / noise is minimal.

All this allows us to talk about solving the technical problem - simplifying and improving the accuracy of the device to determine the optimal therapeutic frequency of the patient.
