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).
