Abstract

An access disconnection system includes an extracorporeal circuit; first and second contacts provided in the extracorporeal circuit; a current source communicating with the first contact and configured to generate a current within fluid flowing through the extracorporeal circuit; and an apparatus positioned to apply a signal at multiple points along a path from the extracorporeal circuit, the signals tending to prevent at least a portion of the current from traveling through a ground path in parallel to the extracorporeal circuit.
