ABSTRACT:
An in-line fluid conduit condition analyzer which includes a chamber placed in the conduit flow path and having one wall forming a piezoceramic bender that varies the chamber volume (or pressure) according to a predetermined waveform or noise spectrum and an associated piezoceramic pressure or displacement sensor. The time derivative of the displacement or the pressure are analyzed under computer control to identify conduit abnormalities. In particular application to intravenous fluid administration to patients, the system is capable of distinguishing a number of abnormalities including cathether obstruction, catheter needle out of the vein, catheter needle into the vein, as well as fluid bubble presence or conduit disconnection.
