MEASURING DEVICE AND METHOD FOR OPTICALLY DETERMINING THE CONCENTRATION OF BLOOD SUGAR AND/OR LACTATE IN BIOLOGICAL SYSTEMS

摘要

The invention relates to a measuring device for optically determining the concentration of blood sugar and/or lactate in biological systems, comprising at least one IR radiation source (3), that radiates IR light on a volume (1) that is to examined, and at least one measuring detector (10) that detects light coming from the volume (1) that is to be examined in order to determine the concentration of blood sugar and/or lactate, also by laymen in a simple manner and anywhere. According to the invention, the IR light radiated on the volume (1) that is to be examined is supplied, prior to entry into the volume (1), to a reference detector.
