Abstract: Air bubbles may be characterized by an air bubble detector by choosing an optimum set of frequencies and then comparing a return signal from a sensor receiving those frequencies against an internal reference. The number of pulses that exceed the internal reference represents a width and may be counted. The width, as counted, may be correlated to bubble characteristics including volume.

Abstract: A feeding set adaptor and related system for delivering solutions utilize a feeding set adaptor which engages a pump engaging portion of an infusion set and the feeding set adaptor structure to provide monitoring portions for detecting pressures within the infusion set, a sample cell for determining the presence of air within an infusion set, and an anti-freeflow device for selectively preventing freeflow through the infusion set. The feeding set adaptor is configured for mounting on an infusion pump which moves solution through the infusion set for delivery to a patient.
