Abstract: Methods are disclosed for providing operationial instructions to a hemodialysis circuit (10) having a dialysis filter (48) and a capability of operating according to a time-varying parameter such as variable ultrafiltration. According to the methods, entered are a desired time period, a target cumulative value of the parameter, such as target ultrafiltration volume, and a proposed time-varying profile of the parameter that is representable as a plot of coordinates in a region defined by an ordinate of values of the parameter and a time-based abscissa defining a profile cumulative value of the parameter. If the profile cumulative value is not equal to the target cumulative value, then the proposed time-varying profile is changed along the ordinate to make the cumulative values equal. The circuit (10) then operates according to the changed profile to achieve the entered target cumulative value within the time period.

Abstract: Apparatuses, devices, systems and methods for detecting access disconnection are provided. The present invention includes electrical contacts in fluid and electrical communication with a fluid passing between a patient and a medical system during therapy. In this regard, the present invention can use a direct-contact measurement to detect access disconnection, such as dislodgment of an access device from the patient through which fluid can flow during therapy including, for example, medication delivery, dialysis therapy and the like.

Abstract: An extracorporeal blood system (10) is described. The system comprises: an extracorporeal blood machine (20, 30) including an extracorporeal blood circuit (16, 35); an access device (36) enabling the extracorporeal blood circuit (16, 35) to be connected to a patient (18); electrical contacts (22, 24) configured to contact blood as the blood flows through the extracorporeal blood circuit (16, 35); and a controller (52) configured to model a total impedance Z according to at least two lumped impedances including (i) a lumped impedance ZD due to components (40, 42, 44, 46) of the extracorporeal blood machine (20, 30) and (ii) a lumped impedance ZP due to access of the extracorporeal blood circuit (16, 35) to the patient (18).
