Non-invasive determination of glucose concentration in body of patient

摘要: Radiation in the near infrared over a limited range of wavelengths about 1660 nanometers is projected on portion body, for example, ear, patient. The resulting radiation emitted by portion, either scattered from or transmitted after absorption and processed to derive an expression as function wavelength. second derivative this very narrow between 1640 1670 expanded glucose concentration determined magnitude, intensity, scatter-ed at maximum minimum point derivative. Also disclosed apparatus non-invasive determination through first fiber-optic conductor outer surface patient's penetrating into portion. A transmits data proces-sing means which produces desired wavelength incident radiation. processor includes spectrum analyzer spec-trum
