    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.

    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: 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 placement guide apparatus with an improved hydration inducing plug used in coupling a noninvasive analyzer to a sampling site to determine analyte in the human body is disclosed. The hydration inducing plug includes at least one fluoropolymer that may be used as a coupling agent. The guide apparatus may further include an automated or semi-automated coupling fluid delivery system. Use of either of these couplers mitigates issues associated with related technology and enhances noninvasive analyte measurements, such as a near-IR diffuse reflectance based noninvasive glucose concentration analyzer.
