A disadvantage of the known devices is the difficulty of implementation and the lack of the possibility of simultaneous therapy with various types of magnetic fields.

The closest analogue in terms of the set of essential features adopted for the prototype is a device for electromagnetic exposure to a biological object according to application No. 201812918 dated 04/09/2018, containing a sequentially coupled clock generator, a unit for generating quasi-random control signals, a modulator with a timer, a microwave signal generator, and a microwave the path, the antenna-emitter, the block of the multi-frequency signal generator and the block of the information signal generator, connected by the outputs to the control voltage generating unit, and that Also, a signal splitter, a block of amplifier keys and a magnetic belt are connected in series with the modulator, and each output of the channel of the signal splitter is connected via an amplifier key to an emitter in the magnetic belt.

The advantage of the prototype is to provide a stable effect on a biological object due to the modulated microwave signal of non-thermal power and low-frequency electromagnetic field. The device provides therapy for various initial functional states of a biological object.

The disadvantages of the prototype are:

- the lack of the possibility of simultaneous exposure to low-frequency and high-frequency magnetic fields for both one patient and two patients;

- lack of diagnostics of the functioning of the device, the output of information about the therapeutic mode, about the self-diagnosis mode, duration of the procedure and device settings;

- the complexity of the implementation of the device.

The task to which the invention is directed is to expand the capabilities of the device.

The technical result in the implementation of the proposed technical solution is the possibility of simultaneous therapy for several patients with different types of alternating electromagnetic fields of non-thermal intensity or for one patient with both types of alternating electromagnetic fields, as well as displaying information about the remaining time of the procedure, choosing the duration and type of exposure, the results of the functional device diagnostics, providing device settings, while the device has a simple layout solution.

The problem is solved, and the technical results are achieved due to the fact that in the known device of the high-frequency and electromagnetic therapy apparatus, containing a series-connected microwave controlled voltage, microwave path, antenna-emitter, as well as series-connected signal and frequency divider, power switches, magnetic belt , A voltage-controlled microwave generator and a signal and frequency divider are connected in series through a digital-to-analog converter and an analog-to-digital converter with a microcontroller, which, in turn, is connected in series with the display and controls.

The installation of an additional microcontroller, digital-to-analog converter allows you to simultaneously generate a modulating signal for high-frequency exposure and the main signal for low-frequency exposure and provide simultaneous therapy for two patients. Also possible

simultaneous exposure to high-frequency and electromagnetic therapy for one patient. The installation of control elements and a display provides a choice of the operating mode of the device: the effect of a low-frequency signal, the effect of a high-frequency signal or the effect of both types of signals, the choice of the duration of the procedure, the countdown of the procedure for each type of exposure, an indication of the end of the effect, an indication of the status of the devices. Installing an analog-to-digital converter provides control of the device. Moreover, the use in the claimed invention of a microcontroller, a digital-to-analog converter, an analog-to-digital converter ensures the simplicity of the layout solution of the device compared to the prototype.

The essence of the claimed technical solution is illustrated by the drawing, which shows a block diagram of an apparatus for high-frequency and electromagnetic therapy.

The apparatus of high-frequency and electromagnetic therapy contains a display 1, a microcontroller 2, control elements 3, a digital-to-analog converter 4, an analog-to-digital converter 5, a microwave controlled voltage 6, a signal and frequency divider 7, a microwave path 8, power switches 9, the antenna emitter 10, magnetic belt 11.

The outputs of the microcontroller 2 are connected to the input of the display 1 and to the input of the digital-to-analog converter 4, and the inputs of the microcontroller 1 are connected to the output of the control elements 3 and the output of the analog-to-digital converter 5. The outputs of the digital-to-analog converter 4 are connected to the input of the microwave generator controlled by voltage 6 and to the input of the signal divider and

frequency 7. The output of a microwave generator controlled by voltage 6 is connected to the input of the microwave path 8, the output of the microwave path 8 is connected to the antenna input of the emitter 8. The output of the signal divider and frequency 7 is connected to the input of the power keys 9, the outputs of the power keys 9 are connected to the inputs of the magnetic belt 11 The inputs of the analog-to-digital Converter 5 are connected to the power input of the microwave generator controlled by voltage 6 and to the power input of the signal divider and frequency 7.

The device operates as follows. After turning on the device, the microcontroller 2 on the display 1 displays the choice of various operating modes, using the control elements 3 carry out the choice of one of several modes prescribed by the doctor:

1) for one patient:

- therapy with a low-frequency signal of a random frequency;

- therapy with a low-frequency “running” signal;

- therapy with a high-frequency signal;

- therapy with a low-frequency signal ("running" type or random frequency) and a high-frequency signal;

2) for two patients:

- therapy with a low-frequency signal ("running" type or random frequency);

- therapy with a high-frequency signal.

Moreover, when conducting therapy to two patients, only different types of exposure can be used: for the first patient, low-frequency therapy, for the second, high-frequency therapy, and vice versa. In this case, the timer value, which is displayed on the display 1, is set using the control elements 3, different for each patient.

After the treatment mode is turned on, microcontroller 2 generates a digital signal of a certain shape and supplies it to a digital-to-analog converter 4, which, in turn, generates a low-frequency signal on different channels. The analog signal coming from the digital-to-analog converter 4 to the microwave generator controlled by voltage 6 has a “sawtooth” shape and frequency, randomly changing in time with a randomly changing frequency change duration (simulating the earth’s field). This signal modulates the microwave signal on the microwave generator controlled by voltage 6, after which the modulated microwave signal is fed through the microwave path 8, is transmitted to the antenna emitter 10, from where the microwave signal is sent to the patient.

Another analog signal coming from the digital-to-analog converter 4 to the signal and frequency divider 7 has a rectangular shape and frequency, a random image changing in time with a randomly changing frequency change duration, or a constant frequency in time. After passing the signal divider and frequency 7, the signals are supplied to the power switches 9 and provide their control, which leads to switching on and off the coils in the magnetic belt 11.

Determining the functioning state of the device is ensured by measuring the voltage drop by an analog-to-digital converter 5 on a microwave generator controlled by voltage 6 and a signal and frequency divider 7 and transferring the measured values to microcontroller 2, where the data is compared with the specified settings, and, in the case of going beyond settings, corresponding warning messages are issued.

As a result of this combination of influences, the effects of a microwave field of non-thermal intensity and a very low magnetic field, which, like the microwave field, is stochastic, a therapeutic effect on a biological object occurs, which for mammals, for example, is expressed in a positive effect on the body, manifestation anesthetic sensations, etc. In the case of plants, for example, localization and a significant decrease in abnormal tissue development occur, while working with cell tissue, a stimulatory effect is performed. Similar positive results have occurred when exposed to humans.
