A needleless valve connector is disclosed. The needleless valve connector includes a movable diaphragm assembly and an internal central cannula. The proximal portion of the internal cannula has a tapered configuration or is slotted to allow it to be radially compressed to form a tapered configuration. The diaphragm is slit and includes cams formed therein to engage the slotted portion of the internal cannula during downward movement of the diaphragm. The engagement of the cams and the proximal portion of the internal cannula facilitates movement of the diaphragm past the proximal portion of the internal cannula.

[ We claim:] [1.] A needleless valve connector, comprising:a housing defining an interior portion, the housing having a proximal portion defining a proximal opening, a medial portion, and a distal portion defining a distal opening;a longitudinally movable diaphragm having a longitudinal axis, a proximal face and a distal face and defining a slit therein extending along the longitudinal axis of the movable diaphragm from the proximal face to the distal face and disposed in the proximal portion of the housing;a biasing mechanism adjacent to the movable diaphragm and disposed in the housing to bias the movable diaphragm toward the proximal opening of the housing; andan internal cannula axially fixed with respect to the housing and defining a lumen therethrough and disposed in the interior portion and defining a longitudinal axis and having a proximal portion located adjacent to the proximal portion of the housing and a distal portion located adjacent to the distal portion of the housing, the proximal portion is fixed to the internal cannula and has a proximal end with an opening therein axially aligned with the lumen and a plurality of slots therein extending from the opening to a position distal of the opening.
