摘要： Systems and methods are disclosed for assessing the functionality of solenoid valve activation in peritoneal dialysis systems. In at least one embodiment, measurements of current values may be received from a solenoid valve at a predetermined sampling rate over a predetermine duration of time to generate a current profile for the solenoid valve. A fifth degree polynomial model may be fit to the current profile and optimized. The optimized polynomial model may be applied to a trained support vector machine to determine whether the current profile indicates that the corresponding solenoid valve has actually opened or closed.

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.

摘要： A peritoneal dialysis (“PD”) system includes a PD fluid pump; a patient line for receiving used PD fluid pumped by the PD fluid pump during a patient drain; a pressure sensor positioned and arranged to sense a negative pressure associated with the PD fluid pumped during the patient drain; and a control unit configured to (i) determine or know a flowrate of the PD fluid pumped during the patient drain, (ii) determine an applied negative pressure at which the PD fluid pump is to pump the PD fluid during the patient drain, the applied pressure based on a pressure drop corresponding to the determined or known flowrate, and (iii) use sensed negative pressure from the pressure sensor to cause the PD fluid pump to pump the PD fluid during the patient drain at the applied negative pressure.

摘要： A dialysis system having motor driven pressure estimation of fluid within a patient line is disclosed. A peritoneal dialysis (“PD”) system includes a fluid pump and a patient line that fluidly couples the fluid pump to an indwelling catheter leading into a patient's peritoneal cavity. The PD system also includes a motor driver that controls a motor of the fluid pump and transmits an output signal that is indicative of a load on the motor. The PD system further includes a machine learning algorithm that associates data related to output signals from motor drivers with known fluid pressures within patient lines. A processor of the PD system transmits an input signal to activate the motor driver, receives the output signal from the motor driver, and estimates a fluid pressure within the patient line by applying the data from the received output signal to the machine learning algorithm.
