User interface for automated peritoneal dialysis systems

Claim 1

An automated peritoneal dialysis system including means for establishing flow communication with a patient's peritoneal cavity through a pumping mechanism, actuator means for operating the pumping mechanism to: (i) drain spent peritoneal dialysis liquid from the peritoneal cavity through, and (ii) infuse fresh dialysis liquid from a source into the peritoneal cavity, control means operable in a first mode directing operation of the actuator means to conduct a first peritoneal dialysis modality and operable in a second mode directing operation of the actuator means to conduct a second peritoneal dialysis modality different than the first modality including a first interface including input means for a user to select the first mode or the second mode, a second interface including adjustment means for a user to adjust one or more individual therapy parameters of the selected modality, first verification means for (i) comparing individual user-adjusted parameters to predetermined individual parameter limits; (ii) generating an error signal when an individual user-adjusted parameter is outside the predetermined individual parameter limits; and (iii) allowing adjustment of the individual parameter when it is within the predetermined individual parameter limits, and second verification means for (i) analyzing the individual therapy parameters allowed by the first verification means to verify that the allowed individual therapy parameters taken together satisfy predetermined composite therapy criteria comprising consideration of at least resulting dwell time or required number of cycles; (ii) returning the user to the second interface to readjust one or more individual therapy parameters when the composite therapy criteria are not satisfied; and (iii) permitting operation of the control means in the selected mode only when the composite therapy criteria are satisfied.
