Abstract: Provided is a blood measurement device capable of accurately estimating the amount of a component contained in blood by passing light beams for calculating the amount of the component contained in blood along the same optical axis. A blood measurement device 10 of the present invention includes a light emitting part 11 having a first light emitting part 111 and a second light emitting part 112, a light receiving part 19, an actuator 16, and a computation and control part 17 that estimates a glucose level and controls operation of the actuator 16. When applicating a first light beam from the first light emitting part 111 to a measurement site, the computation and control part 17 causes the actuator 16 to move a light emission point of the first light emitting part 111 onto an optical axis 22 defined to penetrate through the measurement site, and when applicating a second light beam from the second light emitting part 112 to the measurement site, the computation and control part 17 causes the actuator 16 to move a light emission point of the second light emitting part 112 onto the optical axis 22.

Abstract: A non-invasive glucose sensor used for glucose detection in a subject is provided. The sensor includes a long channel source to excite a first location of a skin and a long channel detector to detect near infrared (NIR) energy emitted from the first location of the skin. A short channel source excites a second location of the skin and a short channel detector detects NIR energy emitted from the second location of the skin. The sensor further includes a long channel processor to process a long channel electrical signal into a glucose spectroscopic data and a short channel processor to process a short channel electrical signal into a background spectroscopic data. The sensor includes a spectroscopic processor to subtract the background spectroscopic data from the glucose spectroscopic data, and thereby to produce data indicative of a quantity of glucose present in the subject's blood.

Abstract: An optical physiological sensor configured to perform high speed spectral sweep analysis of sample tissue being measured to non-invasively predict an analyte level of a patient. An emitter of the optical physiological sensor can be regulated to operate at different temperatures to emit radiation at different wavelengths. Variation in emitter drive current, duty cycle, and forward voltage can also be used to cause the emitter to emit a range of wavelengths. Informative spectral data can be obtained during the sweeping of specific wavelength regions of sample tissue.
