Abstract
Intravenous administration set for use with a source of liquid to be administered intravenously and having a length of flexible tube with a fitting carried on one end of the same adapted to be connected to the source of liquid. A burette is provided which has a chamber formed therein. The other end of the flexible tube is mounted in the burette so that liquid passing through the tube flows into the burette chamber. A filter assembly is carried by the burette and has a recess formed therein. A projection extends into the recess and defines at least a portion of an outlet opening for withdrawing liquid from the burette chamber. The filter assembly includes a hydrophillic filter which provides the only path for the flow of liquid and gas into the recess. The member and the projection are formed in such a manner that all liquid passing through the outlet opening must pass into the recess through the filter and carry with it any gas in the recess. Tubing is connected to the outlet opening in communication with the burette chamber and is adapted to be coupled to the patient which is to be intravenously fed.
