DIALYSIS SYSTEM HAVING ADAPTIVE PRESCRIPTION MANAGEMENT
An example peritoneal dialysis system is disclosed. The example peritoneal dialysis system includes at least one pump and a memory device configured to store therapy prescriptions including a low ultrafiltration (“UF”) therapy prescription, a first standard UF therapy prescription with a longer duration and a lower dextrose concentration, and a second standard UF therapy prescription with a shorter duration and a higher dextrose concentration. The memory device also stores a schedule indicative as to which of the therapy prescriptions are to be performed on specified dates. The system further includes a logic implementer configured to determine or identify a current date, use the schedule stored in the memory device to select the therapy prescription based on the current date, and control the at least one pump based on the selected therapy prescription to perform a peritoneal dialysis therapy.
Method for regulating the supply of substituate during extracorporeal blood treatment and extracorporeal blood treatment device comprising a unit for regulating the supply of substituate
The present invention relates to a method for regulating supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. Moreover, the present invention relates to an extracorporeal blood treatment apparatus having a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.

MODULAR ASSEMBLY FOR A PORTABLE HEMODIALYSIS SYSTEM
A modular assembly for a portable hemodialysis system may include a dialysis unit, e.g., that contains suitable components for performing hemodialysis, such as a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer, and a power unit having a housing that contains suitable components for providing operating power to the pumps of the dialysis unit. The power unit may be selectively connected to the dialysis unit and provide power (e.g., pneumatic power in the form of pressure and/or to vacuum) to the dialysis unit for the pumps when connected to the dialysis unit, but may be incapable of providing power to the dialysis unit when disconnected from the dialysis unit. The dialysis unit and the power unit are sized and weighted to each be carried by hand by a human.
