Abstract:
1. A blood sugar level measuring apparatus comprising: a heat amount measurement portion for measuring a plurality of temperatures derived from a body surface and obtaining information used for calculating the amount of heat transferred by convection and the amount of heat transferred by radiation, both related to the dissipation of heat from said body surface; an oxygen amount measuring portion for obtaining information about blood oxygen amount; a storage portion for storing a relationship between parameters individually corresponding to said plurality of temperatures and blood oxygen amount and blood sugar levels; a calculating portion which converts a plurality of measurement values fed from said heat amount measuring portion and said oxygen amount measurement portion into said parameters, and which computes a blood sugar level by applying said parameters to said relationship stored in said storage portion; a display portion for displaying the blood sugar level calculated by said calculating portion; and an apparatus chassis, wherein said oxygen-amount measuring portion comprises a blood flow volume measuring portion for obtaining information about the volume of blood flow, and an optical measuring portion for obtaining hemoglobin concentration and hemoglobin oxygen saturation in blood, said blood flow volume measuring portion comprises a body-surface contact portion, an adjacent-temperature detector disposed adjacent to said body-surface contact portion, an indirect-temperature detector for detecting the temperature at a position spaced away from said body-surface contact portion, and a heat-conducting member connecting said body-surface contact portion and said indirect-temperature detector, and said apparatus chassis comprises a plurality of legs on a bottom surface thereof for supporting itself.
