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.

The invention involves the monitoring of a biological parameter through a compact analyzer. The preferred apparatus is a spectrometer based system that is attached continuously or semi-continuously to a human subject and collects spectral measurements that are used to determine a biological parameter in the sampled tissue. The preferred target analyze is glucose. The preferred analyzer is a near-IR based glucose analyzer for determining the glucose concentration in the body.

A blood glucose monitoring system includes a broadband light source and a specially fabricated optical filter for modulating optical radiation to be transmitted through a fleshy medium. Optical radiation which passes through the fleshy medium is detected by an optical detector which generates an electrical signal indicative of the intensity of the detected light. Digital signal processing is performed on the electrical signal to extract those optical characteristics of the electrical signal due ...

A glucose measuring device for determining the concentration of glucose in intravascular blood within a body part of a subject. The device includes light sources having a wavelength of 650, 880, 940 or 1300 nm to illuminate the fluid. Receptors associated with the light sources for receiving light and generating a transmission signal representing the light transmitted are also provided. A support piece is including for supporting the light sources associated with their respective light sources. ...

In accordance with the invention, a low coherence interferometer is used to non-invasively monitor the concentration of glucose in blood by shining a light over a surface area of human or animal tissue, continuously scanning the light over a two dimensional area of the surface, collecting the reflected light from within the tissue and constructively interfering this reflected light with light reflected along a reference path to scan the tissue in depth. Since the reflection spectrum is sensitive...

Glucose concentration is noninvasively measured by measuring a plurality of absorption values using at least one emitter operating at a corresponding plurality of emission wavelengths through a common optical sample volume and deriving glucose concentration from the absorption measurement values.

This application describes designs, implementations, and techniques for optically monitoring glucose levels of patients without taking blood samples.

A method and device are provided for self-monitoring a patient's blood glucose condition to determine a long-term effect of the patient's behavior on his blood glucose level. A sequence of measurements of the blood glucose level is applied during a day, the sequential measurements are repeated during a predetermined time period from several days to several weeks, and measured data are collected. The measured data is analyzed to determine a distribution of the average glucose values within said p...

The invention relates generally to the extraction and/or presentation of glucose concentrations estimated as a function of time into a format that facilitates conveyance of the underlying information. More particularly, glucose concentration histories are presented in terms of risk of behavior, in a video format, and/or in an audio format. The reduction of data into video format, selected by time period, cluster, or glucose concentration response, into an animated or video presentation allows di...
