Abstract
A method for locating a catheter tip within a human body is disclosed. An audio sensor is positioned at a site on the human body. An audio signal is detected by the audio sensor, and transmitted to an audio signal processing unit. The audio signal processing unit determines if the audio signal corresponds to a target location of the catheter tip, and transmits a notification signal to a user notification unit. An infusion of fluid or an audio emitting element can be used to generate the audio signal at the catheter tip.
