Blood sugar levels are non-invasively measured based on temperature measurements. Blood sugar levels obtained by non-invasive measurements of temperatures are corrected by blood oxygen saturation and the volume of blood flow so that the measurement data can be stabilized.

Blood sugar level measuring apparatus

Blood sugar levels are measured non-invasively based on temperature measurement. Non-invasively measured blood sugar level values obtained by a temperature measurement scheme are corrected by blood oxygen saturation and blood flow volume, thereby stabilizing the measurement data. A guide is provided for guiding an analyte to a measurement portion.

Measuring apparatus for measuring a metabolic characteristic in a human body

Blood sugar levels are measured non-invasively based on temperature measurement. Values of blood sugar levels non-invasively measured by a temperature measuring system are corrected using blood oxygen saturation and blood flow volume. Optical sensors are provided for detecting scattered light, reflected light, and light that enters into the skin which travels out of the body surface. The measurement data is stabilized by taking into consideration the influence of the thickness of skin on blood oxygen saturation.

Blood sugar levels are measured non-invasively based on temperature measurement. Non-invasively measured blood sugar level values obtained by a temperature measurement scheme are corrected by blood oxygen saturation and blood flow volume, thereby stabilizing the measurement data. If the measured blood sugar level is larger than a warning value, a warning is issued.

Blood sugar levels are measured non-invasively based on temperature measurement. Non-invasively measured blood sugar level values obtained by a temperature measurement scheme are corrected by blood oxygen saturation and blood flow volume, thereby stabilizing the measurement data. The shape or color of control buttons for controlling measurement are associated with the function of each button such that the buttons can be identified either visually or by touch.

Blood sugar levels are measured non-invasively based on temperature measurement. Non-invasively measured blood sugar level values obtained by a temperature measurement scheme are corrected by blood oxygen saturation and blood flow volume, thereby stabilizing the measurement data.

Blood sugar levels are measured in a non-invasive way based on temperature measurement. Different regression functions are used for an able-bodied person and a diabetic patient when stabilizing measurement data by correcting a non-invasively measured blood sugar level, i.e. a value obtained by temperature measurement, with blood oxygen saturation and blood flow volume.

Blood sugar level measuring method and apparatus

Blood sugar levels are non-invasively measured based on temperature measurements. An insulation structure is employed in a temperature measurement part for measuring heat amount and non-invasively obtained blood sugar level measurements are corrected by blood oxygen saturation and the volume of blood flow so that the measurement data can be stabilized and the measurement accuracy can be enhanced.

Blood sugar levels are measured non-invasively based on temperature measurement. Measured blood sugar levels are corrected using blood oxygen saturation and blood flow volume. The measurement data is further stabilized by taking into consideration the influences of interfering substances on blood oxygen saturation.
