Dialysis system and disposable set

A peritoneal dialysis system comprising:

• an automated peritoneal dialysis (“APD”) machine including a pumping mechanism, a logic implementer, and a peritoneal dialysis fluid heater;
• a disposable set including
• a dextrose supply,
• a disposable cassette in fluid communication with the dextrose supply and operable with the pumping mechanism, and
• a heater bag operable with the heater for mixing peritoneal dialysis fluid;
• and
• a conductivity sensor located so as to sense conductivity of the peritoneal dialysis fluid mixed in the heater bag and to provide feedback to the APD machine, wherein the APD machine is configured to mix the peritoneal dialysis fluid for treatment in the heater bag using a constituent fluid from the dextrose supply,
• wherein the logic implementer is configured to control the mixing of the peritoneal dialysis fluid to achieve a specified concentration while the peritoneal dialysis fluid is heated in the heater bag, receive the feedback from the conductivity sensor, and use the feedback to ensure that the pumping mechanism has pumped the constituent fluid into the heater bag for mixing the peritoneal dialysis fluid so as to achieve the specified concentration.
