ABSTRACT:
An apparatus and a method are provided for collecting samples of used dialysate during hemodialysis treatments. A fluid sample is branched off from the main flow of used dialysate into a sample receiving container. The branching off of the sample flow, i.e. withdrawal of the fluid sample, is either time- or volume-controlled so that during the course of a dialysis treatment a predetermined number of fluid samples are withdrawn, whereby the total sample volume has a prescribed ratio relative to the total volume of used dialysate. The recirculation and sample withdrawal conduit is selectively attachable to the sample receiving container for sample collection, or to the inlet of the hemodialysis device to form a recirculation loop for a disinfection cycle. A disinfectant cartridge can be interposed between the recirculation conduit and the hemodialysis device inlet.
