APPARATUS FOR DETERMINATION OF pH, pCO2, HEMOGLOBIN AND HEMOGLOBIN OXYGEN SATURATION

摘要

An apparatus for measuring molecular constituents comprising an optically transmissive housing (26), first and second light sources (36, 38), a detector (42, 44) for detecting the first and second wavelengths, and a diffuser (92) for providing the illuminating light with a broad angular dispersion.
