ABSTRACT:
A low profile filter assembly for use in IV sets and the like includes a pair of spaced apart, axially aligned inlet and outlet filter adaptors secured to inlet and outlet ends, respectively, of a filter tube. A generally conically shaped filter member is connected at its opposite ends to the inlet and outlet filter adaptors and extends longitudinally within the filter tube between the adaptors. Lengths of flexible IV tubing are connected with the adaptors for conveying fluid to and from the filter assembly. The filter cone is disposed with its larger end connected to the inlet adaptor and its smaller end connected to the outlet adaptor and the filter assembly diameter is only about twice the diameter of the tubing connected therewith, yet a filter area many times greater than the cross-sectional area of the tubing is obtained. Additionally, the filter is simple and economical to assemble.
