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 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： A method and apparatus using photo-stimulation to treat or pretreat a sample site prior to analyte concentration determination is presented. More particularly, photo-stimulation at or near at least one sample site is used to enhance perfusion of the sample site leading to reduced errors associated with sampling. Increased perfusion of the sample site leads to increased volume percentages of the target analyte and/or allows the blood or tissue constituent concentrations to more accurately and/or precisely track corresponding sample constituents in more well perfused body compartments or sites such as arteries, veins, or fingertips. In one embodiment, analysis of the photo-stimulated site is used in conjunction with glucose analyzers to determine the analyte concentration with greater ease, accuracy, or precision and may allow determination of the analyte concentration of another non-sampled body part or compartment.

摘要： An apparatus and method for reproducibly interfacing a living tissue sample to the measurement probe of a spectrometer instrument in-situ minimizes spectral interference related to sampling variations. A minimal contact subject interface includes supports replaceably mounted on a base. An optical coupling means, such as a fiber optic probe, contacts the measurement site through a probe aperture in the base. During use, a subject rests an extremity on the support elements, so that the extremity is reproducibly positioned and supported in relation to the optical coupling means. The supports have a small contact area, minimizing contact with the skin at the measurement site. The interface module is adjustable to fit any subject.By reproducibly positioning and supporting the body appendage using minimal contact supports, spectral interference due to variations in placement, applied pressure, and temperature transients secondary to contact with the interface module are greatly minimized.
