A multi-lumen sensing system () includes medical tubing () having a plurality of lumens (A,B) and at least one secondary passageway () extending in an axial direction of the medical tubing, wherein the secondary passageway is between the plurality of lumens. The multi-lumen sensing system may include a sensing receptacle () defining a channel () in which a lengthwise portion of the medical tubing is received. A plurality of ultrasonic transmitting elements (T,T) may be arranged within the secondary passageway of the medical tubing or as part of the sensing receptacle for transmitting respective ultrasonic signals across the lumens to a corresponding plurality of ultrasonic receiving elements (R,R) of the sensing receptacle. Alternatively, the sensing receptacle may include a plurality of ultrasonic transmitting and receiving elements () transmitting respective signals across the lumens for return reflection at an interface of the secondary passageway.

A universal air bubble detector allows for use with a variety of sizes and types of tubing. The detector maintains proper alignment of a sensor emitter and receiver with different sizes of tubing. The detector may be mounted on existing equipment or may be used to monitor a tubing at any position along the tubing, and may operate in a stand alone mode or in combination with existing equipment.
