摘要： A peritoneal dialysis (“PD”) system includes a PD fluid pump, a disinfection loop including the PD fluid pump, the disinfection loop including PD fluid used for disinfecting the disinfection loop, and an acid solution source positioned and arranged to supply an acid solution to the disinfection loop during disinfection using the PD fluid. The disinfection loop includes an airtrap and a pressure sensor positioned and arranged to sense PD fluid pressure during disinfection, the pressure sensor outputting to a control unit, the control unit configured to open at least one gas valve located along at least one gas line leading to an upper portion of the airtrap when the PD fluid pressure reaches or exceeds a threshold PD fluid pressure due to gas formation caused by mixing the acid solution with the PD fluid.

摘要： A peritoneal dialysis (“PD”) system includes a plurality of PD fluid components, a reusable PD fluid line selectively fluidly communicating with the PD fluid components, a source of PD fluid selectively fluidly communicating with the reusable PD fluid line, a source of anti-scaling fluid selectively fluidly communicating with the reusable PD fluid line, and a control unit configured to (i) operate the plurality of PD fluid components during treatment using PD fluid from the source heated to a treatment temperature, and (ii) circulate unused PD fluid heated to a disinfection temperature in combination with anti-scaling fluid from the source of anti-scaling fluid after treatment for disinfecting the plurality of PD fluid components and the reusable PD fluid line, the anti-scaling fluid provided in an amount configured to lower the pH of the unused PD fluid to a level below which precipitates are formed and above which the pH causes disinfection.
