  • Patent number: 11918721
    Abstract: 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.

  • Patent number: 11752245
    Abstract: A system and method are disclosed for the automated collection of dialysis data. An example method includes receiving and aggregating dialysis data comprising a fill volume amount and a drain volume amount for at least one continuous ambulatory peritoneal dialysis (“CAPD”) cycle. The method also includes calculating an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle, and storing ultrafiltration data that is indicative of the amount of ultrafiltration removed as part of the aggregated dialysis data. The method further includes determining or receiving an indication that a dialysis machine is connected. After the dialysis machine is connected, the method includes transmitting the aggregated dialysis data to the dialysis machine to enable the aggregated dialysis data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data.
