A vented syringe adapter assembly which includes a housing having a sidewall, bottom wall, and top wall, which walls combine to define a chamber within the housing. A dual lumen tubular conduit extends through the top wall, chamber and bottom wall with one end extending from the top wall and defining a syringe connector port and the opposite end extending from the bottom wall and defining a piercing tip. A first lumen extends through the tubular conduit from the syringe port to the piercing tip. A second lumen extends from the piercing tip to the inner chamber. An opening is provided on at least one of the walls of the housing and the opening is covered by a filter for allowing the passage of gases but preventing the flow of liquids through the opening.

A vented syringe adapter assembly comprising: a first housing portion comprising a single lumen tubular conduit and a generally circular planar surface extending outwardly from and between the ends of the single lumen tubular conduit such that the lumen extends centrally through the first housing portion, the single lumen tubular conduit including syringe connector means on a first end and a recess on its second end through which the centrally extending lumen opens; a second sidewall housing portion comprising a generally cylindrical sidewall, a planar surface having provided openings therethrough, which planar surface extends across and joins the cylindrical sidewall, and a dual lumen tubular conduit extending through the planar surface generally parallel to the cylindrical sidewall with one of the lumens extending centrally through the second housing portion, wherein a first end of the dual lumen tubular conduit extends to define a piercing tip with both lumens opening therealong and second end which includes an opening for the centrally extending lumen and which second end extends to coincide with the recess on the second end of the single lumen tubular conduit, the second lumen of the dual lumen tubular conduit opens on the planar surface of such second housing portion, the second housing portion further comprising a circular recess on the planar surface, the first housing portion and second housing portions being interconnectable such that the circular planar surface of the first housing portion interconnects to the cylindrical sidewall of the second housing portion to form a chamber defined by the planar surface of the first housing portion and cylindrical surface and planar surface of the second housing portion and such that the second end of the dual lumen tubular conduit interconnects with the recess on the second end of the single lumen tubular conduit to provide one lumen extending through the combined first and second housing portions and one lumen opening into the chamber; and a generally circular hydrophobic filter provided in the recess on the circular planar surface of the second portion, which hydrophobic filter extends over the provided openings.
