METHOD FOR NON-INVASIVE BLOOD GLUCOSE TEST Russian patent published in 2014 - IPC A61B5/145 A61B5/01 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely therapy and endocrinology, and can be used for glycaemia monitoring. Glycaemia values are indirectly shown by measured temperature and/or thermal flows by means of sensors of a measuring instrument in the region of superficial veins of the head. That is followed by a pre-calibration of the given blood glucose levels derived by the non-invasive method and the measured values by formula: X_g ^*=X₁ ^*+X₂ ^*, wherein X₁ ^*=K_tfW_tf(s)X_t ^*, X₂ ^*=K_fW_tf(s)X_f ^*, wherein X_t ^* is a non-dimensional temperature overshoot, X_f ^* is a non-dimensional thermal flow overshoot, W_tf(s)=e^-τs is a transfer function of the blood glucose level shown by temperature and the thermal flow, τ is a blood glucose change delay in relation to temperature overshoot, K_tf, K_f are calibration coefficients, s=d/dt is a differentiation operator. The calibration coefficients and the delay time are adjusted automatically by data randomly supplied to a calculation unit and derived by the non-invasive method.

EFFECT: method enables high-accuracy glycaemia monitoring by systematic adjustment of the calibration coefficients and the delay time.
