METHOD FOR DETERMINING GLUCOSE CONCENTRATION IN NONINVASIVE WAY Russian patent published in 2002 - IPC

FIELD: medicine. SUBSTANCE: method involves determining blood glucose concentration by means of measuring instrument. Continuous blood glucose concentration monitoring is carried out by measuring heat flows in the area of head superficial veins by means of measuring instrument transducer. Glucose concentration ((X*g

)) is calculated from a formula X*g = X*1+X*2, where X*1 = W_Thf(s)X*T, X*2 = K_hfW_Thf(s)X*hf,, where X*T - the dimensionless temperature from steady state value, X*hf - the dimensionless heat flow deviation from steady state value, W_Thf(s) = 1/(T_Thf x S+1) is the transition function of blood glucose concentration with respect to temperature and heat flow, T_Thf is the experimentally stated transient process time constant K_hf is the experimentally stated dimensionless coefficient, s = d/dt is the differentiation operator. Z- thermistors are used as temperature pickups pressed against head surface by means of elastic member and insulated from ambient space by means of heat insulation members. Glucose concentration information is represented by means of tonal signal and display unit. EFFECT: enhanced accuracy of measurements. 3 cl, 2 dwg, 2 tbl
