Abstract
An air-in-line sensing apparatus for use with a parenteral fluid administration set to detect the passage of air through a fluid conduit. The apparatus comprises a first housing having a first arcuate section mounting a first transducer adjacent the first arcuate section and a second housing having a second arcuate section mounting a second transducer adjacent the second arcuate section. One housing is independently movable relative to the other housing so that when the movable housing is moved towards the other housing, the first and second arcuate sections capture a length of administration set tubing therebetween providing secure intimate contact therewith. A signal may be generated from one of such transducers, passed through the fluid conduit and received by the other transducer to detect whether the conduit is carrying air.
