Abstract: A peritoneal dialysis system (10) comprises a cycler (20) including a pump actuator (60); a disposable set including a pumping portion (126) operable with the pump actuator (60), a patient line (122e) positioned to fluidly communicate with the pumping portion (126), and a drain container (124a) positioned to fluidly communicate with the pumping portion (126); and a control unit (50) configured to cause the pump actuator (60) to actuate the pumping portion (126) to (i) run a peritoneal dialysis treatment in which fresh dialysis fluid is pumped through the patient line (122e) to a patient and used dialysis fluid is pumped from the patient to the drain container (124a), and (ii) at the end of treatment, pump the used dialysis fluid from the drain container (124a), through the patient line (122e), to a house drain.

Abstract: An automated peritoneal dialysis system (10) comprising: a dialysis fluid pump actuator (60); a dialysis fluid carrying set (120) including a flexible sheet (136); a temperature sensor (38) positioned and arranged to sense a temperature of the dialysis fluid flowing through the dialysis fluid carrying set (120); a pressure sensor (36a, 36b) positioned and arranged to contact the flexible sheet (136) when the dialysis fluid carrying set (120) is loaded for operation with the dialysis fluid pump actuator (60); and a control unit (50) configured to (i) precondition the flexible sheet (136) for operation with the pressure sensor (36a, 36b) by causing the dialysis fluid pump actuator (60) to apply pressure to the flexible sheet (136) and (ii) use an output from the temperature sensor (38) in a compensation algorithm that modifies an output from the pressure sensor (36a, 36b).

Abstract: A peritoneal dialysis system (10) comprises a cycler (20) including a pump actuator (60), a patient line valve actuator (34e), at least one supply line valve actuator (34b, 34c), and a drain line valve actuator (34a); and a disposable medical fluid cassette (130) including a pumping portion (126) configured to operate with the pump actuator (60), a patient line valve seat (132e) configured to operate with the patient line valve actuator (34e), a rigid body (138) defining a common well (146), at least one supply line valve seat (132b, 132c) located in the common well (146) and configured to operate with at least one supply line valve actuator (34b, 34c), and a drain line valve seat (132a) located in the common well (146) and configured to operate with the drain line valve actuator (34a).
