Abstract: Methods, apparatuses, and systems for determining a correlation between intraperitoneal pressure ("IPP") measurements and patient intraperitoneal volume ("IPV") are disclosed. In an example, an apparatus is configured to determine a maximum fill volume of dialysate to be pumped into a peritoneal cavity of a patient. The apparatus also determines a plurality of iterations to achieve the maximum fill volume and a volume of the dialysate to be pumped for each of the iterations. For each iteration, the apparatus causes a dialysis machine to pump the dialysate to the peritoneal cavity based on the determined volume for that iteration, records IPP measurement output data from a pressure sensor, records or determines a total accumulated fill volume, and creates a data point for a personalized patient model corresponding to a correlation between the IPP measurement output data and the total accumulated fill volume.

Abstract: A peritoneal dialysis system includes a water purifier; a disposable set including a water line in fluid communication with the water purifier, a drain line for draining from the disposable set, and a disposable container including at least one chamber, the disposable container including at least one concentrate in one of the at least one chamber, and the disposable container positioned and arranged to hold a dialysis fluid prepared by mixing water from the water purifier and the at least one concentrate; and a control unit in communication with at least one sensor, for detecting a first property of water from the water purifier and a second property of the dialysis fluid.

Abstract: A peritoneal dialysis ("PD") system includes a cycler having a weigh scale, a chamber for weighing by the weigh scale, a heater, a plurality of valves, a pump, and a control unit operable with the weigh scale, the heater, the plurality of valves and the pump; and a disposable set including a PD fluid container fitting within the chamber for weighing and heating, a supply line in fluid communication with the PD fluid container, a drain container fitting within the chamber for weighing, a drain line in fluid communication with the drain container, and a patient line positioned on an opposing side of the pump from the supply line and the drain lines, wherein the control unit is configured to operate the plurality of valves and the pump to pump used dialysis fluid to the drain container and fresh dialysis fluid from the PD fluid container.
