METHOD AND APPARATUS FOR DETERMINING QUANTITY OF UREMIC TOXIN REMOVED BY HEMODIALYSIS TREATMENT

摘要

PPROBLEM TO BE SOLVED: To provide a method and apparatus of hemodialysis capable of avoiding the drawbacks of the usual hemodialysis method and apparatus, and economically optimizing the cost of necessary quantity of dialysis. PSOLUTION: 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 124. The extraction of the shunt sample flow, or the fluid sample, is controlled by time or the volume so that predetermined numbers of fluid samples are extracted during the dialysis treatment process. And so the total sample volume has a prescribed ratio relative to the total volume of used dialysate. An extraction conduit 121 for recirculation and sample extraction 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. PCOPYRIGHT: (C)2006,JPO&NCIPI
