Description

 The invention relates to medical equipment, in particular to EHF-therapy.

 Known devices for EHF-therapy, which are sources of coherent electromagnetic radiation of low power, operating at the same frequency in the EHF range and capable of expanding the possibilities of therapeutic effects on the body to tune in frequency in the range of several percent of the average operating frequency. Such a restructuring allows us to find the optimal frequency of EHF exposure from the point of view of the therapeutic effect. However, the possibility of determining the optimal frequency of EHF exposure involves the development of methods for reliable determination of the optimal frequency. This is a disadvantage of the known device to reliably determine the optimal frequency in a short time (≈ 1 h), without changing the patient's condition, without the use of complex and expensive EHF-diagnostic settings is impossible. When using this device, you usually have to rely on the subjective sensations of the patient. Such sensations are not directly related to certain disorders in the body. And since the body can have a variety of disorders at the same time, relying on such a subjective diagnosis, they often go the wrong way when implementing the treatment process, that is, they affect the body with EHF radiation at frequencies that do not affect the violation to be eliminated. Many patients may not experience any sensations during the EHF treatment session.

 To overcome these disadvantages of the device, a combination of EHF-diagnostic devices and EHF-therapeutic devices is used.

 But such a combination of equipment is quite complicated and expensive. It can be resorted to only when treating extremely severe patients in the most difficult cases to cure, i.e. a small percentage of the total number of patients.

 The aim of the invention is the creation of a device that allows in the vast majority of cases to ensure close to optimal process of EHF-therapy using relatively simple EHF-equipment. The exception is only extremely severe patients, for the treatment of which, as noted above, it is necessary to resort to equipment in which the number of frequencies used in the EHF range exceeds 2.

To do this, using the proposed device (used to treat ulcers of the stomach and duodenum), which includes two frequency-tunable EHF generators with medium frequencies f ₁ and f ₂ (only modulation of the generated signals within narrow limits, of the order of 0.1- 1% of the average frequency).

The ratio of frequencies f ₁ and f ₂ should be within
1.27 <f ₁ / f ₂ <1.45 In the known device, the ratio f ₁ / f ₂ was not optimal and amounted to 1.26. All other possible features of the proposed devices are not of fundamental importance and, in particular, may coincide with the design features of known devices.

The proposed devices provide for the possibility of including signals with frequencies f ₁ and f ₂ for irradiating the surface of the patient’s body, both alternately and together, as well as the possibility of using any of the signals separately.

 The use of such a device provides automatic frequency conversion of external signals (within one octave) in the patient's body in cells with impaired (deviated from the norm) functioning, which eliminates the need for tunable external (with respect to the body) generators. The latter are complex and unreliable if (as in the case under consideration) it is a question of the need to ensure the exact coincidence of the frequencies of the effective signals (affecting the body's cells) with the frequencies characterizing the disturbances in the corresponding cells.

Practice has shown that the use of some known devices for the treatment of gastric and duodenal ulcers provides complete scarring of ulcers in 65-75% of cases, the use of other known devices allows for complete scarring in 90-95% of cases (results were tested for 7000 patients). To further increase this percentage, the different frequencies f ₁ and f ₂ should be further expanded (taking into account the non-linear characteristics of the frequency conversion in the body to one octave). It is easy to calculate that the frequency conversion range of one octave is provided by the signal frequency ratio f ₁ / f ₂ , approximately equal to 1.45 (a slight excess of the octave at f ₁ / f ₂ 1.45 is designed to compensate for possible frequency instability). As the ratio of signal frequencies f ₁ / f ₂ decreases below 1.27, the percentage of curability of patients gradually decreases to 65-70%
The advantages of the proposed device for EHF-therapy of gastric and duodenal ulcers are obvious. The use of only two generators, moreover, with fixed frequencies, eliminates the need for preliminary EHF diagnostics; periodic monitoring of the state during the course of treatment is sufficient. Operation is simplified to the limit. The cost of a therapeutic unit is reduced and the percentage of curability rises sharply in comparison with the case of using EHF-therapeutic units operating at one fixed or tunable frequency.

 The proposed device for EHF-therapy can be used not only for the treatment of gastric and duodenal ulcers, but also with other nosologies.
