Abstract

An ultrasonic air-in-line detection system for use in detecting air bubbles in the fluid line of a disposable cassette mounted on a main pump unit is disclosed which automatically loads the outlet tubing at the bottom of the cassette into a slot in an ultrasonic sensor housing when the cassette is installed on the main pump unit. The system uses a tubing adapter mounted on the outlet tube below the cassette, with the tubing adapter having a tapered top end. The tubing adapter interacts with a pair of ramps located on the bottom and front of the ultrasonic sensor housing around the slot to draw the tubing adapter into a recess located on the bottom of the ultrasonic sensor housing, thereby drawing the outlet tubing fully into the slot between an ultrasonic transmitter and an ultrasonic receiver in the ultrasonic sensor housing when the cassette is installed.
