    摘要: A near-infrared spectrometer-based analyzer attaches continuously or semi-continuously to a human subject and is used to collect spectral measurements of a tissue sample. The spectral readings are used to estimate a biological parameter in the sampled tissue noninvasively, such as glucose concentration. The preferred apparatus is a near-infrared analyzer that includes a base module and a sample module connected together with a communication bundle. The base module contains the bulk of the analyzer, such as a spectrograph and a central processing unit with an algorithm used for converting the optical signal into a glucose concentration. The sample module is typically in a smaller module that interfaces to a tissue sample. The sample module is preferably handheld and provides minimal sampling distortion due to heat or pressure.

    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.

    摘要: Sampling is controlled to enhance analyte concentration estimation derived from noninvasive sampling. Means of assuring that the same tissue sample volume is repeatably sampled are presented, thus minimizing sampling errors due to mechanical tissue distortion, specular reflectance, and probe placement. In a first embodiment of the invention, sampling is controlled using automated delivery of a coupling fluid to a region between a tip of a sample probe and a tissue measurement site in a manner requiring minimal user interaction. In a second embodiment of the invention, sampling is controlled by controlling temperature variations, preferably with a coupling fluid, at a region about the tip of a sample probe and a sample site. In a third embodiment, sampling is procedurally controlled via timing and location of coupling fluid delivery to a sample site.
