Patent ID: 7120478

Claim:
A blood sugar level measuring apparatus comprising: a heat amount measuring unit for measuring a plurality of temperatures derived from the body surface in order to obtain information used for calculating the amount of convective heat transfer and the amount of radiation heat transfer concerning the dissipation of heat from the body surface; an oxygen volume measuring unit for obtaining information concerning the volume of blood oxygen; a storage unit for storing the relationships between the individual parameters corresponding to the multiple temperatures and blood oxygen volume and blood sugar levels; a computing unit for converting the measurement values provided by the heat amount measuring unit and the oxygen volume measuring unit into parameters, and computing a blood sugar level by applying the parameters to the relationships stored in the storage unit; and a display unit for displaying the blood sugar level computed by the computing unit, wherein the oxygen volume measuring unit comprises a blood flow volume measuring unit for obtaining information concerning the volume of blood flow and a heat transfer prevention means for preventing heat transfer to the blood flow volume measuring unit from the vicinity thereof, wherein the blood flow volume measuring unit comprises: a body-surface contact unit; an adjacent temperature detector disposed adjacent the body-surface contact unit; an indirect temperature detector for detecting the temperature at a position distanced away from the body-surface contact unit; and a heat-conducting member connecting the body-surface contact unit and the indirect temperature detector, wherein the heat transfer prevention means prevents heat transfer to the heat-conducting member.
