ABSTRACT:
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.
