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： Systems and methods are disclosed for verifying reference voltage and analog-to-digital converter (“ADC”) values during medical fluid treatment. An example system comprises a control circuit including control ADC devices associated with respective control sensors to facilitate medical fluid treatment; and a protective circuit including protective ADC devices associated with protective sensors, wherein the control circuit and the protective circuit are galvanically isolated from one another; and a computing device having a memory and a processor. The computing device may be configured to initiate a pretreatment that exposes the control sensors and the protective sensors to common pretreatment conditions (e.g., temperature and pressure); receive, during the pretreatment, control ADC values and protective ADC values; and register an error for one or both of the control circuit or the protective circuit based on a comparison of a control ADC value with a protective ADC value.
