<p><P>PROBLEM TO BE SOLVED: To provide a blood component concentration analysis method and device for improving the SN ratio of a measurement signal for improving the measurement accuracy, while reducing the size and the cost of a measurement device, wherein the variation of blood component concentration can be calculated, to improve measurement accuracy. <P>SOLUTION: A light emitting part 19 at the other end of a light-emitting optical fiber 7 connected at one end to a light source 1 emits a near-infrared light to a surface layer tissue 6 of a living body, and a light-receiving part 20 at the other end of a light-receiving optical fiber 7' connected at one end to a light-receiving element 15 receives it; the light-emitting part 19 and the light-receiving part 20 are arranged at a space of 0.2-2 mm; the near-infrared light, having a wavelength of 1,100-2,500 nm, is emitted as a correcting light to find a correcting coefficient from a light-emitting amount and a light-receiving amount; and the near infrared light, having a wavelength of 1,100-2,500 nm, is emitted as a measuring light, to quantitatively analyze the blood component concentration from the light-emitting amount and the light-receiving amount, and the correcting coefficient. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
