摘要： A method is presented for checking the integrity of a hollow-fibre fluid filter, in particular a hollow-fibre dialyzer (1), which is constructed from a plurality of hollow fibres (15) enclosed by a membrane, with the steps of: perfusing the inside or outside of the hollow fibres (15) with a fluid, supplying the outside or inside of the hollow fibres (15) with a gas, wherein the gas has a higher pressure than the fluid, and determining a quantity of the gas which penetrates into the fluid through holes in the membrane. The method is characterized in that, after flowing through the hollow-fibre fluid filter (1), the fluid is channelled through a bubble trap (30), and in that a volume of gas (41) collecting in the bubble trap (30) during a predefined or predefinable reference period is determined. Furthermore, equipment for checking the integrity of a hollow-fibre fluid filter (1) is presented.

摘要： A hemodialysis system is disclosed. The hemodialysis system includes a dialyzer and an online dialysate generation system comprising a water inlet line and a drain line. The hemodialysis system also includes a disposable set comprising a supply tube fluidly connected to online dialysate generation system and a dialysate pumping tube fluidly connected to the dialyzer. The hemodialysis system further includes a dialysis instrument comprising a dialysate pump head and a motor positioned and arranged to operate the dialysate pump head. The dialysis instrument operates the dialysate pump head to move fresh dialysate from the online dialysate generation system through the dialysate pumping tube to the dialyzer.

摘要： A renal failure therapy system for performing a peritoneal dialysis therapy is disclosed. The renal failure therapy system performs a plurality of peritoneal dialysis cycles for a patient and tracks an amount of dialysis fluid provided by a dialysis fluid pump during the plurality of peritoneal dialysis cycles. The renal failure therapy system also determines, as an initial drain volume, how much dialysis fluid resides in the patient's peritoneal cavity at a start of a next dialysis treatment and determines an initial drain flow for the next dialysis treatment. The renal failure therapy system generates an alert when it is determined from the initial drain flow that a low drain flow or a drain flow stoppage could occur before the initial drain volume is recovered for the start of the next dialysis treatment.

摘要： A method for performing a peritoneal dialysis therapy includes performing a plurality of peritoneal dialysis cycles for a patient and tracking an amount of dialysis fluid provided by at least one dialysis fluid pump during the plurality of peritoneal dialysis cycles. The method also includes determining an amount of ultrafiltrate (“UF”) removed from the patient based on the amount of dialysis fluid provided by the at least one dialysis fluid pump. The method further includes updating a UF trend using previous amounts of UF removed from the patient and the amount of UF removed from the patient during the most recent dialysis treatment and generating an alert if the UF trend changes by more than a preset percentage.
