The indicated terminals and elements of express diagnostics are connected to the control panel through the corresponding connector and are configured to perform scheduled and express diagnostics, affect biological objects simultaneously or sequentially in time, obtain information on the display of a personal computer and compare information about the patient’s condition before and after physiotherapeutic effects.

However, despite the high automation for medical diagnostics, it is not intended for the study of therapeutic compositions according to the radio response spectra.

Closest to the claimed device is a device for researching objects of EHF by the influence of patent RU 2108058. It contains an MM generator of the electromagnetic wave range, a radio receiver of the object, radiating and receiving antennas connected through the object by radio wave communication, a piston assembly formed by the receiving antenna applicator serving a piston and a hollow cylinder of radiolucent material with a removable liner in it of non-wettable radiolucent material, and the receiver is made in the form of a radiometer HF - centimeter, decimetre, meter or the radio.

However, this device has limited performance and functionality, and accuracy and reliability are not high enough.

The objective of the utility model is to create a multifunctional analytical complex that combines at the same time the possibilities of researching a person, biological objects and therapeutic compositions.

The essence of the utility model is that in the analytical device for the study of biological objects, which includes an emitter of electromagnetic waves in the form of an EHF generator and an antenna, an receiver of an electromagnetic signal in the form of a microwave radiometer with an applicator antenna, a power supply for the analyzing device, the following are entered: a control panel containing a coproller, analog-to-digital converter (ADC), keyboard, sound alarm unit, light alarm unit, control panel power supply; the command bus, a computer and a programmable power supply connected to the emitter of electromagnetic waves, and the command bus connects the controller to the programmable power supply and the computer is connected to the controller, the microwave radiometer - to the ADC, and all elements of the analytical device, except the computer, are placed in a shielding box.

In addition, the essence of the utility model lies in the fact that the inventive analytical device for the study of biological objects additionally has a decoder inserted into the microwave radiometer and connected to the controller of the command.

The device is illustrated using the figure, which shows the block diagram, where the positions 1-16 indicate the blocks and elements of the claimed utility model.

The device consists of a receiver in the form of a microwave radiometer 1 with a decoder 2 and an applicator antenna 3, a control panel 7, comprising: a controller 4, an analog-to-digital converter 5, a power supply 15, an audible alarm unit 14 and a light signaling unit 16; Pschny teams 8, programmable power supply 9, emitter of electromagnetic waves in the form of EHF generator 10 and antenna 11, computer 12, shielding box 13. Elements of the device are connected as follows. The microwave radiometer is connected to the analog-to-digital converter 5 of controller 4, which is connected to the keyboard 6 and the bus for control commands 8. A programmable power supply 9 connected to the command bus 8 and connected to the EHF generator 10, the output of which is connected to the antenna 11. Computer 12 is connected with controller 4 coaxial line for serial exchange of information. All units of the device, with the exception of computers, can be placed, for example, in one metal case that improves shielding from electromagnetic interference. The bioobject and all units of the device, with the exception of the personal computer 12, are placed in a shielded box 13. Shielding is necessary to protect against electromagnetic interference, since the microwave radio responses are comparable in magnitude with the level of the thermal background. Reliable reception of radio responses requires the use of highly sensitive receivers () capable of operating under conditions of high shielding from radio interference. For the same reason, a personal computer 12 that emits radio frequency interference in a wide band has been taken out of the shielded box. The blocks of the complex, placed inside a shielded box, have reliable shielding, filters in the power supply circuit and do not emit interference.

The claimed device operates as follows. After connecting the complex to an AC network, all its blocks and functional elements are automatically set to their original state in 20 minutes. From the keyboard 6, the analysis mode is turned on, the controller 4 starts to draw commands to the programmable power supply 9. From its output, the stabilized voltage is supplied to the EHF generator 10. From the output of the EHF generator, the radiation enters the antenna 11 and is directed to

selected area of the patient’s body. The microwave signal of the radio response from the irradiated region of the body is applied to the receiving applicator antenna 3. From the output of the antenna, the signal is fed to the input of the microwave radiometer 1, where it is converted to constant charge proportional to the value of the radio response and fed to the analog input of the ADC 5 of controller 4. There, the signal is converted to digital form and remembered. After that, the controller 4 gives the command to perform the next measurement and generates the following code, which passes through the command bus 8 to the input of the programmable power supply 9. So, step by step, the spectrum of the radio response is taken from the patient’s body area. In the process of taking the spectra according to the commands of the controller 4, received via the command bus 8 to the input of the decoder 2 of the microwave radiometer 1, the correction of the operating parameters of the radiometer is performed: the time constant of signal accumulation and the interval of measured powers. This allows one to obtain the maximum spectral detail in a wide dynamic range of changes in the radio response power. Controller 4 performs the initial processing of the recorded spectrum and displays the results in the form of a diagram on its screen along with the corresponding reference spectrum. The most important steps when performing analytical, therapeutic or diagnostic procedures are accompanied by sound signals from block 14 and light signals from block 16. Then the operator can repeat the spectrum acquisition or send the result to the personal computer 12, which is equipped with an on-site system that allows you to analyze fragments of the received spectrum and compare them with samples from the library of standards. It is possible to supplement the operating system with new algorithms for the chemical analysis of drugs, biological fluids, including patients, as well as new algorithms for medical diagnostics in the process of conducting scientific research.
