    摘要: 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).

    摘要: Apparatuses, devices, systems and methods for detecting access disconnection during medical therapy are provided. The present invention includes an electric circuit coupled to, for example, a blood circuit used during dialysis therapy. The electric circuit can be adapted to inject an electrical signal into the blood circuit such that changes in an electrical valve in response to access disconnection, such as needle drop-out or catheter drop-out, can be effectively detected.
