Abstract:
1. An apparatus for a measurement of at least one analyte in blood of a patient, comprising: a light source generating broadband light; a light-transmission arrangement including at least one transmitting fiber positioned for simultaneously transmitting multiple wavelengths of said broadband light from said light source to the blood of the patient; an optical fiber arrangement having at least one light detector fiber for leading multi-wavelength light, in spectrally unseparated form, transmitted through, or reflected from, the blood; a light detection arrangement receiving said multi-wavelength light in its spectrally unseparated form from said optical fiber arrangement, for spectrally decomposing the received light, and for determining amplitudes of selected wavelengths of the decomposed light; and, means for utilizing solely a non-pulsatile element of the blood of the patient for determining a measurement of at least one analyte in the blood as a function of the amplitudes of the selected wavelengths.
