Peritoneal dialysis system including peristaltic pump

A peritoneal dialysis system comprising:

• a disposable set including
• a pressure sensing manifold including first and second pressure sensing pods,
• a drain line and a dialysis fluid/heater container line in fluid communication with the first pressure sensing pod, and
• at least one additional dialysis fluid container line and a patient line in fluid communication with the second pressure sensing pod;
• a cycler including:
• a peristaltic pump actuator,
• a first valve actuator configured to operate with the first pressure sensing pod to allow dialysis fluid to selectively flow to either the drain line or the dialysis fluid/heater container line, and
• a second valve actuator configured to operate with the second pressure sensing pod to allow dialysis fluid to selectively flow to either the patient line or one of the at least one additional dialysis fluid container line;
• and
• a control unit programmed to operate the peristaltic pump actuator (i) in a first direction to pump fresh dialysis fluid along the at least one additional dialysis fluid container line into the dialysis fluid/heater container line, and (ii) in a reverse, second direction to pump heated, fresh dialysis fluid along the dialysis fluid/heater container line into the patient line.
