Abstract
The invention describes an apparatus for extracorporeal blood treatment with a dialyzer which is separated by a semipermeable membrane in to a first and second chamber (29, 30), wherein the first chamber (29) is arrange in a dialysate pathway and the second chamber (30) is connectable to the blood circulation of a patient by means of a blood supply conduit (32) and a blood return conduit (31), an inlet (20) for fresh dialysate, an outlet (30) for spent dialysate, a measuring device (37) arranged in the outlet (36), wherein said measuring device (37) has at least one radiation source consisting of several light sources (1) for electromagnetic radiation. The invention is characterized in that the measuring device (37) is designed to generate substantially monochromatic electromagnetic radiation of different wavelengths, and to lead only one of these wavelength (at the same time) though the outlet (36) for spent dialysate, wherein at least one detector system (5) is provided for detection of the intensity or the absorption of the substantially monochromatic electromagnetic radiation passing through the outlet (36) for spent dialysate.
