ABSTRACT:
An apparatus (1) for the drawing off of untreated and treated dialyzing liquid and/or blood from a dialysis device (1) has a dialyzer, from which a first line (22) goes off upstream and a second line (24) goes off downstream, which join into a third line (54). The third line (54) is connected to an analysis device (57). In each of the first and second lines is provided a pump (26, 28) and a shut-off element (56, 56'), between which an overflow (38, 40) per line is arranged. This on the one hand ensures that the liquid in the lines (22, 24) are kept constantly in motion, which prevents the formation of line blockages in the case of liquids tending to coagulate, and on the other hand considerably reduces the displacement time of the liquid to be investigated to the analysis device (57).
