Dialysis system having pump reversing disinfection

Abstract

A peritoneal dialysis (“PD”) system includes a housing, a PD fluid pump housed by the housing, an inline heater in fluid communication with the PD fluid pump, a temperature sensor, and a control unit. The PD fluid pump and the inline heater are under control of the control unit, which receives a temperature signal from the temperature sensor. The control unit, in one embodiment, is configured to perform a heat disinfection sequence in which the control unit causes the PD fluid pump to pump disinfection fluid in a forward direction, while the inline heater heats the disinfection fluid, and in a reverse direction after the temperature signal indicates that a temperature of the disinfection fluid has fallen to or has fallen below a minimum disinfection temperature.
