METHOD FOR DETERMINING INDIVIDUAL'S BLOOD GLUCOSE CONCENTRATION Russian patent published in 2014 - IPC A61B5/145 A61B5/53 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. Determining an individual's blood glucose concentration is ensured by measuring high-frequency and low-frequency body region impedances successfully at pre-set intervals of time with using spaced electrodes fixed on the body. The measured high-frequency impedance provides the basis to determine a fluid volume in the body tissues between the electrodes, while the measured low-frequency impedance is used to determine an extracellular fluid volume in the body tissues between the electrodes. That is followed by deriving a metabolic component increment of the above extracellular fluid volume formed by the body energy carrier synthesis and recovery by calculating an increment of the above measured fluid volume in the body tissues between the electrodes as compared to the previous measured value, calculating a difference of the above increment of the fluid volume in the body tissues between the electrodes and the above increment of the extracellular fluid volume in the body tissues between the electrodes. A blood glucose increment is measured by standardising the above metabolic component increment of the extracellular fluid volume, while the individual's blood glucose concentration is determined by summing up the above glucose concentration increment and the blood glucose concentration derived at the previous stage of measurements. The glucose concentration at the first interval of time is determined by summing up the above blood glucose increment derived at the first interval of time and the initial glucose concentration.

EFFECT: method enables continuous and non-invasive high-accuracy determination of the individual's blood glucose concentration.
