  • Patent number: 7254427
    Abstract: 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.

  • Patent number: 7156810
    Abstract: 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.

  • Publication number: 20060094941
    Abstract: An apparatus for non-invasively measuring blood sugar levels based on temperature measurements. A blood sugar level non-invasively measured by a temperature measuring method is corrected by blood oxygen saturation and blood flow volume. Optical sensors detect scattered light, reflected light, and light exiting from a body surface after penetrating the skin, so that measurement data can be stabilized by taking into consideration the influence of the thickness of the skin on blood oxygen saturation.

  • Publication number: 20060084853
    Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Measurement data is stabilized by correcting blood sugar level measurement values obtained by a temperature measuring system in a non-invasive manner based on the blood oxygen saturation and the blood flow volume. An LCD portion 13 is raised from a horizontal direction by an angle ? of 15° to 60° so as to prevent the generation of noise due to radiation heat from body surfaces other than the user's finger.

  • Publication number: 20060084854
    Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Measurement data is stabilized by correcting a non-invasive blood sugar level measurement value obtained by a temperature measuring system on the basis of the blood oxygen saturation and the blood flow volume. A heat conducting member is provided in a blood flow volume measurement portion that measures the blood flow volume based on temperature detection. The heat conducting member is made up of a cylindrical main body 61 and a plate-like support plate 63 disposed in the longitudinal direction of an internal cavity of the main body. A first temperature detector 23 is fixed to an end portion of the support plate and is disposed within the internal cavity of the main body. A second temperature detector 24 is fixed on an external surface of the main body.

  • Publication number: 20060079742
    Abstract: A method and apparatus for non-invasively measuring blood sugar levels based on temperature measurement. A non-invasively determined blood sugar level measurement value is corrected on the basis of the blood oxygen saturation value and the blood flow volume, thereby stabilizing measurement data. A measurement portion is provided with a cover with which the measurement portion can be covered and protected when not in use. By controlling the opening and closing of the cover, erroneous measurement can be prevented. The intensity of a detection signal in an optical system is corrected by a circuit.
