Abstract

A connector adapted to facilitate medicinal access into an intravenous tube includes a housing having a base and a cap defining a channel through the housing. A valve element disposed in the channel includes a plug and elastomeric shaft which biases the plug into sealing engagement with the housing. Operation of the connector by inserting a male Luer fitting in the housing axially compresses the valve element to a canted position thereby permitting medicinal access through the channel and into the intravenous tube. Canting of the valve element can be facilitated by providing a finger along the channel or by providing a predetermined buckling section along the valve element. The shaft of the valve element can be rounded and disposed in an arcuate cavity of the housing to further facilitate canting of the valve element.
