Abstract
The development of instruments and control devices in medicine is aimed at achieving the quality of complex manipulation operations. The use of mechatronic principles for the construction of automatic devices ensures the creation of new methods and instruments for laboratory analyses. We have developed a mechatronic system of the device for a noninvasive method for determining the concentration of blood glucose on the basis of modeling the correlation between systemic hemodynamic parameters and biological parameters of blood. A functional multivariate analysis was carried out, a computer program was compiled, and mathematical regression formulas were obtained for calculating the level of blood glycaemia based on blood pressure indicators. The mechatronic system includes functional blocks for measuring blood pressure parameters, a control microcontroller for calculating and monitoring blood glucose levels in accordance with the application program.The system is implemented in the form of a noninvasive device «Omelon B-2», which provides the transfer of indicators to the display of the device, communication with the base computer of the system, analysis of the results and creation of a database. The blood glucose measurement range is from 2 to 20 mmol/l. The relative error of the analysis in comparison with laboratory parameters is 17-22%.
