METHOD OF DETERMINING GLUCOSE CONCENTRATION IN BLOOD Russian patent published in 2012 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, in particular to endocrinology. In order to determine glucose concentration in blood, in the morning, on empty stomach, systolic and diastolic arterial pressure is measured successively on patient's left and right hands. Ratio n of the greatest of measured values of systolic arterial pressure on left and right hands to the lowest of measured values of diastolic arterial pressure on left and right hands is registered. Concentration of glucose in blood is determined by ratio n by calibration characteristics. Calibration is carried out apriori on the borders of adaptive range for patients with known glucose content and registered ratio n, by which maximum ratio n₀ of systolic pressure to diastolic pressure and maximum content of P₀ glucose content in blood are found, which are used to build calibration characteristic for determination of real content of glucose in blood P by formula, mmol/l: where n₀ = (n₂ - n₁) / ln(P₂ / P₁) and and P₁ and P₂ are known values of glucose content in blood, n₁ and n₂ are registered ratios of systolic pressure to diastolic pressure for known values P₁ and P₂, k=n₁/n₂.

EFFECT: method increases metrological efficiency of determining glucose concentration in blood by arterial pressure due to elimination of methodical error.
