Title: Instrument for measuring degree of saturation of oxygen
Inventor: KONO HIROMASA
IPC: G01N21/31
Filed: 1987-07-24
Abstract: PURPOSE:To obtain the value of an exact degree of saturation of oxygen even in a region of a low degree of saturation of oxygen by detecting the intensity of the light which is projected into blood from 1st-3rd light projecting means and is reflected from the blood. CONSTITUTION:This instrument is provided with the 1st light projecting means E which projects the light of a 1st wavelength into the blood, a 2nd light projecting means F which projects the light of the 2nd wavelength different from the light of the 1st wavelength into the blood and the 3rd light projecting means G which projects the light of the 2nd wavelength into the blood. A detecting means 2 detects the intensity of the light projected from the light projecting means E, F, G into the blood. A 1st correction value is then computed 40 from the reference value of hemoglobin concn. A 2nd correction value is then computed 42 by using the 1st correction value outputted by the computing means 40 and the intensity of the reflected light of the light projected from the light projecting means G. The ratio of the corrected intensities of the reflected light of the intensities of the light of the projected E and F light is computed 44 by using the 2nd correction value. Finally, the degree of saturation of oxygen in the blood is determined by computation 4 using the ratio of the corrected intensities of the reflected light.
