1. An acoustic line tracing system for tracing a fluid transfer system tubing line, the tracing system comprising:
- an infusion pump;
a first acoustic receiver operably connectable to the tubing line and configured to receive a vibratory signal, the first acoustic receiver including;
a first vibration sensor disposed to contact the tubing line, said first vibration sensor being configured for detecting vibration of the surface of the tubing line caused by the vibratory signal;
a signal transmitter operatively contacting the tubing line and electrically coupled with said first acoustic receiver, said signal transmitter configured for generating acoustic vibrations in the tubing line when said first vibration sensor detects the vibratory signal; and
wherein the first acoustic receiver is upstream from the infusion pump and the signal transmitter is downstream from the infusion pump for reducing dampening of the vibratory signal by the infusion pump.

Abstract
An acoustic line tracing system for tracing a fluid transfer system tubing line includes an acoustic receiver operably connectable to the tubing line and configured to receive the vibratory signal. The acoustic receiver includes a vibration sensor disposed to contact the tubing line and configured for detecting vibration of the surface of the tubing line caused by the vibratory signal, and an indicator producing at least one of an audio and a visual cue when the vibration sensor detects the vibratory signal.
