Claim Text:
1. A system for tracing tubing which forms a conduit from a source of infusion liquid to a patient by way of an infusion pump, the system comprising: a vibration generator manually operable by a user to generate vibrations at an origin location along the tubing, wherein the vibrations are propagated by the tubing and have a vibration signature; a vibration sensor arranged at a destination location along the tubing for receiving the propagated vibrations and generating a digital vibration signal representative of the received vibrations; signal processing circuitry connected to the vibration sensor, wherein the signal processing circuitry is configured to process and evaluate the digital vibration signal to determine a trace status of the tubing between the vibration generator and the vibration sensor, wherein the signal processing circuitry determines a cross-over trace status when the tubing is touched by other tubing; and an indicator connected to the signal processing circuitry, wherein the indicator is configured to provide an audible or visual indication of the determined trace status.
