Abstract
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 inject an electrical signal into the blood circuit such that changes in an electrical value in response to access disconnection, such as needle drop-out or catheter drop-out, can be effectively detected.
