DEVICE AND METHOD FOR MEASURING BLOOD CONSTITUENTS

摘要

The method and device serve to measure a proportion of constituents in blood . To this end, electromagnetic radiation of different radiation wavelengths is directed through a tissue (9) containing blood vessels (1). At least a porti on of the radiation exiting the vessel is detected using sensors, and a corresponding measured value derived therefrom is fed to an evaluating devic e. The evaluating device (10) is connected to at least two sensors (2, 3, 4) an d has an analyzer (11) for determining a dispersion of radiation by evaluating the intensity of the radiation received by the individual sensors. An individual calibration determination is carried out by evaluating the angle- dependent dispersion and can be drawn upon for conducting a pulse spectroscopic determination of concentrations of substances.
