Abstract
An access disconnection method for a machine employing a blood circuit, the blood circuit having a machine segment and a patient access segment, the method comprising: injecting an electrical signal into the blood circuit between the machine segment and the patient access segment; attempting to cause the electrical signal to flow through only the patient access segment and to bypass the machine segment; and measuring the signal in the patient access segment and determining that an access disconnection event has occurred upon a threshold change in the measured signal.
