摘要： A peritoneal dialysis system is disclosed. An example peritoneal dialysis system includes a water treatment device including a water treatment processor and a first memory and a peritoneal dialysis (“PD”) machine including a PD processor and a second memory. The PD machine is configured to mix water treated by the water treatment device with at least one concentrate to produce a peritoneal dialysis fluid for treatment. The example peritoneal dialysis system also includes a data link between the water treatment processor and the PD processor. The water treatment device is configured to prepare an amount of treated water and, upon communication between the water treatment processor and PD processor over the data link, deliver the amount of the treated water to the PD machine for use in mixing the peritoneal dialysis fluid for the treatment. The treated water has a purity corresponding to an injectable quality or a sterile quality.

摘要： A dialysis system is disclosed. An example dialysis system includes a water treatment device configured to provide purified water and a dialysis machine including a dialysate holding tank, and a dialysate mixing pump connected to a source of concentrate. The dialysis machine is configured to prepare dialysate using the purified water by receiving an indication that a batch of dialysate is needed, transmitting a first message to the water treatment device to begin providing the purified water, and causing the dialysate mixing pump to pump a concentrate from the source of concentrate for mixing with the purified water to form the dialysate for storage in the dialysate holding tank. After the batch of the dialysate has been stored to the dialysate holding tank, the dialysis machine transmits a second message to the water treatment device to stop providing the purified water.

摘要： A flow regulation device is disclosed. The flow regulation device is fluidly located between a fluid source and a dialysis machine. In some embodiments, the flow regulation device includes an inlet in fluid communication with the fluid source to receive a fluid and an outlet in fluid communication with the dialysis machine to provide the fluid. The flow regulation device also includes a closed volume defined by walls that are configured to expand and contract to provide a variable internal volume. A cross-sectional width of the variable internal volume of the flow regulation device is larger than diameters of the inlet and the outlet to smooth changes in a draw rate of the fluid from the dialysis machine.

摘要： A fluid preparation apparatus for a renal failure treatment is disclosed. In an example, the fluid preparation apparatus includes an inlet configured to receive water from a water source and a fluid line fluidly connected to the inlet. The apparatus also includes a pump fluidly connected to the fluid line. The pump is configured to pump concentrate from a concentrate container to mix with the water to form a fluid mixture. The apparatus further includes a sensor configured to measure a composition characteristic of the fluid mixture. Additionally, the apparatus includes a controller operably coupled to the pump, the sensor, and a valve. The controller is configured to receive a composition characteristic value from the sensor, and cause the valve to route the fluid mixture for the renal failure treatment when the composition characteristic value indicates that the fluid mixture is suitable for the renal failure treatment.
