Dialysis system having a disinfection unit

A peritoneal dialysis (“PD”) system comprising:

• a PD machine including
• a housing,
• a PD fluid pump housed by the housing,
• a patient line in fluid communication with the PD fluid pump,
• a patient line connector positioned and arranged at the housing to accept a distal end of the patient line to perform a disinfection sequence,
• a plurality of PD fluid lines, and
• a plurality of PD fluid line connectors positioned and arranged at the housing to accept distal ends of the PD fluid lines to perform the disinfection sequence;
• and
• a disinfection unit including
• a disinfection unit housing,
• a PD fluid line connector positioned and arranged at the disinfection unit housing for receiving one of the PD fluid lines of the PD machine for the disinfection sequence,
• a line extending from the disinfection unit housing for connecting to one of the PD fluid line connectors of the PD machine for the disinfection sequence, and
• a disinfection fluid pump housed by the disinfection unit for pumping disinfection fluid during the disinfection sequence.

A peritoneal dialysis (“PD”) system comprising:

• a PD machine including
• a PD machine control unit,
• a PD fluid pump under control of the PD machine control unit;
• and
• a disinfection unit configured to be placed in disinfection fluid communication with the PD machine, the disinfection unit including
• a disinfection unit control unit configured to be placed in data communication with the PD machine control unit, and
• a disinfection fluid pump under control of the disinfection unit control unit,
• wherein the PD machine control unit is configured to automatically command the disinfection unit control unit to cause the disinfection fluid pump to begin pumping disinfection fluid in a disinfection sequence.
