摘要： An apparatus (100) for detecting acoustic reflections that arise from within a tube and body conduit, the tube having a proximal end and a distal end, the apparatus coupled to the proximal end, the distal end of the tube inserted into the body conduit, the apparatus comprising: a sound generator (104) positioned to generate a sound signal in the tube; a sensor (106) for detecting a sound signal in the tube at a distal position relative to the sound generator, and for generating a signal corresponding to the detected sound signal; and a compliant tube (108) aligned with the sensor and configured to transmit sound pressure waves from within the compliant tube to the sensor.

摘要： An apparatus for acoustically detecting the location of a distal end of a tube relative to a body conduit into which the tube is being inserted is provided. The apparatus including a speaker positioned to generate a sound pulse in the tube and a sensor for detecting a sound pulse in the tube at a distal position relative to the speaker, and for generating a signal corresponding to the detected sound pulse.
