A system for producing fluid for peritoneal dialysis (PD) is disclosed. The system includes a fluid path including two or more PD concentrate connectors that are each connected to a source of PD concentrate fluid, and an inlet connector connected to a fluid line arranged for transportation of effluent fluid from a patient. The system also includes a forward osmosis (FO)-unit including a draw side and a feed side separated by a FO-membrane. The FO-unit is fluidly connected to the fluid path and receives one or more PD concentrate fluids at the draw side and the effluent at the feed side. Water is transported from the effluent to the one or more PD concentrate fluids through the FO-membrane via an osmotic pressure gradient between the draw side and the feed side, thereby diluting the one or more PD concentrate fluids into a diluted PD concentrate fluid.

System and method for producing fluid for peritoneal dialysis

A method and apparatus for evaluating a condition of a water purification system () comprising a water purification apparatus () arranged to output purified water through an outlet () and through at least one sterilizing grade filter () of a line set () fluidly connected to the outlet (), the method comprises: monitoring a flow rate (S) correlated with the flow rate of the purified water flowing through the at least one sterilizing grade filter (70); monitoring a pressure (S) correlated with the pressure of the purified water flowing to the at least one sterilizing grade filter (); and evaluating (S) a condition of the water purification system based on a relationship between the monitored flow rate and the monitored pressure.

Method and an apparatus for evaluating a condition of a water purification system

Disclosed herein is a water purification apparatus capable of being cleaned at a point of care, and methods for cleaning the water purification apparatus at the point of care. The water purification apparatus and the methods provide an efficient use of a heater for heat disinfection the water purification apparatus, e.g. by recirculating heated fluid to further heat the fluid. Several different cleaning programs are provided that may be utilized for cleaning different parts of the water purification apparatus.

Water purification apparatus and methods for cleaning the water purification apparatus

A system and a method for renal replacement therapy includes a blood treatment unit connected to a blood circuit and a dialysis fluid circuit, the system further including a control unit configured to control the system according to control instructions during a treatment, so as to determine a system parameter value and an indication of membrane fouling of the membrane, and activate an automatic anti-fouling measure that includes a temporary change of the flow rate in the blood circuit and a temporary decrease of the ultrafiltration rate wherein a timing of the temporary change and a timing of the temporary reduction are synchronized.

System and a method for renal replacement therapy

A water purification apparatus and method for optimizing efficiency of the water purification apparatus comprising a fluid circuit including a Reverse Osmosis, RO, unit (), providing a permeate flow, and an electrically controlled deionization unit () downstream the RO unit () receiving at least part of the permeate flow. The method comprises obtaining (S) a value indicative of power consumption by the electrically controlled deionization unit and determining (S) whether the obtained value indicative of the power consumption meets at least one criterion. The method further comprises controlling recirculation of reject water produced by the water purification apparatus, based on a result of the determining (S), in order to optimize efficiency of the water purification apparatus.
