摘要： A method and apparatus for minimizing confounding effects in a noninvasive in-vivo spectral measurement caused by fluctuations in tissue state monitors a selected tissue state parameter spectroscopically and maintains the selected parameter within a target range, at which spectral effects attributable to the changes in the selected parameter are minimized. The invention includes both active and passive control. A preferred embodiment of the invention provides a method and apparatus for minimizing the confounding effects in near IR spectral measurements attributable to shifts in skin temperature at a tissue measurement site. Spectroscopic monitoring of skin temperature at the measurement site provides near-instantaneous temperature readings by eliminating thermal time constants. A thermistor positioned at the measurement site provides active control. The spectrometer and the temperature control device are incorporated into a single instrument for noninvasive measurement of blood glucose concentration.

摘要： A method and apparatus for noninvasive glucose measurement measures glucose indirectly from the natural response of tissue to variations in analyte concentration. The indirect measurement method utilizes factors affected by or correlated with the concentration of glucose, such as refractive index, electrolyte distribution or tissue scattering. Measurement reliability is greatly improved by stabilizing optical properties of the tissue at the measurement site, thus blood perfusion rates at the sample site are regulated. Perfusion is monitored and stabilized by spectroscopically measuring a control parameter, such as skin temperature, that directly affects perfusion. The control parameter is maintained in a range about a set point, thus stabilizing perfusion. Skin temperature is controlled using a variety of means, including the use of active heating and cooling elements, passive devices, such as thermal wraps, and through the use of a heated coupling medium having favorable heat transfer properties.

摘要： An optical sampling interface system minimizes and compensates error resulting from sampling variations and measurement site state fluctuations. Components include: An optical probe placement guide having an aperture wherein the optical probe is received, facilitates repeatable placement accuracy on surface of a tissue measurement site with minimal, repeatable disturbance to surface tissue. The aperture creates a tissue meniscus that minimizes interference due to surface irregularities and controls variation in tissue volume sampled; an occlusive element placed over the tissue meniscus isolates the meniscus from environmental fluctuations, stabilizing hydration at the site and thus, surface tension; an optical coupling medium eliminates air gaps between skin surface and optical probe; a bias correction element applies a bias correction to spectral measurements, and associated analyte measurements. When the guide is replaced, a new bias correction is determined for measurements done with the new placement. Separate components of system can be individually deployed.

摘要： A fiber optic probe placement guide minimizes sampling errors during optical sampling of a tissue measurement site by allowing repeatable placement of the fiber optic probe at a targeted tissue measurement site. A mount, contoured to conform to the shape of the tissue measurement site, typically the arm of a human subject, contains an aperture for receiving a fiber optic probe. A temperature probe on the contact surface of the guide allows for monitoring of surface temperature within the vicinity of the tissue measurement site. Crosshair slots in the mount align with corresponding crosshairs at the tissue measurement site. The fiber optic probe placement guide is affixed to the tissue measurement site by means of adhesive tape or fastenable straps. Guideposts on the external surface of the mount are received by corresponding receptacles on a subject interface bearing the fiber optic probe to facilitate alignment of the fiber optic probe with the aperture.

摘要： A method and apparatus for calibrating noninvasive or implantable glucose analyzers that uses either alternative invasive glucose determinations or noninvasive glucose determinations to calibrate noninvasive or implantable glucose analyzers. Use of an alternative invasive or noninvasive glucose determination in the calibration allows minimization of errors due to sampling methodology, and spatial and temporal variations that are built into the calibration model. An additional embodiment uses statistical correlations between noninvasive and alternative invasive glucose determinations and traditional invasive glucose determinations to adjust noninvasive or alternative invasive glucose concentrations to traditional invasive glucose concentrations. The invention provides a means for calibrating on the basis of glucose determinations that reflect the matrix observed and the variable measured by the analyzer more closely. A glucose analyzer couples an invasive fingerstick meter to a noninvasive glucose analyzer for calibration, validation, adaptation, and safety check of the calibration model embodied in the noninvasive analyzer.

摘要： Sampling is controlled in order to enhance analyte concentration estimation derived from noninvasive sampling. More particularly, sampling is controlled using controlled fluid delivery to a region between a tip of a sample probe and a tissue measurement site. The controlled fluid delivery enhances coverage of a skin sample site with the thin layer of fluid. Delivery of contact fluid is controlled in terms of spatial delivery, volume, thickness, distribution, temperature, and/or pressure.

摘要： An apparatus and method for non-destructively estimating a tissue property, such as hydration, of a living subject utilizes in vivo spectral measurements made by irradiating skin tissue with near infrared (NIR) light. The apparatus includes a spectroscopic instrument in conjunction with a subject interface. The resulting spectra are passed to an analyzer for further processing, which includes detecting and eliminating invalid spectral measurements, and preprocessing to increase the signal-to-noise ratio. Finally, an estimation model developed from an exemplary set of measurements is applied to predict the tissue hydration for the sample. The method of tissue hydration measurement provides additional information about primary sources of systematic tissue variability, namely, the water content of the epidermal layer of skin and the penetration depth of the incident light. Tissue hydration measurement is therefore suitable for further spectral analysis and quantification of biological and chemical compounds, such as analytes.
