Abstract
A vented connector, used with male Luer tip fitting, is disclosed. The connector includes axial and bifurcating portions. The axial portion includes an exterior housing and interior post. The lumen of the post forms a continuum with an air inlet. The air inlet is furnished with a filter or membrane element, selectively allowing for the flow of air to pass therethrough while preventing an outflow of fluids therefrom. The outer diameter of the post is smaller than the inner diameter of male Luer tip fitting. This provides for a fluid flow in-between the exterior surface of the post and the interior surface of male Luer tip fitting; whereas the flow of air that is drawn into the connector from the inlet, passes via the post into the interior lumen of a receptacle, without intermingling with the concomitantly fluid flow from the receptacle.
