Abstract
A device for determining a dialysis efficiency/dialysis dose of an extracorporeal blood treatment process has a radiation source, a cuvette, a detection unit and a control unit. The radiation source emits radiation, the intensity of which is controlled by adjusting a current intensity applied to the radiation source. The cuvette is preferably provided with an inlet and outlet, and is penetrated by radiation emitted by the radiation source. The detection unit detects the intensity of the radiation after the radiation passes the cuvette. The control unit determines the dialysis efficiency/dialysis dose from the intensity detected by the detection unit. The control unit, which is connected to the radiation source and detection unit, reduces the intensity of the radiation by adjusting the current intensity during the extracorporeal blood treatment process at least once, based on a drop in concentration of substances excreted in the urine in the dialysis fluid.
