Verbesserte Phiolenverbindung für einen Arzneimittelbehälter

摘要

A connector assembly (10) provided for efficient flow of liquid into and/or out of a vial, such as a vial (12) containing a lyophilized drug. The connector assembly features a collar (30) mountable to the rim of the vial in a locked position and thereafter removable by an end-user when disposal of the device is desired. A protective cap (50) mountable over the collar includes a annulus-type ring (61) at its proximal end which mounts over locking structure associated with the collar. The ring is secured to the protective cap via one or more user-severable connections. As the cap is urged proximally, the ring places the collar in the locked position with the vial rim, exerting an inwardly-directed force onto the locking structure to secure the collar to the vial rim. The cap (50) can be separated from the ring (61) at its user-servable connections, and the device used in its ordinary matter. When disposal is desired, the ring may be urged proximally out of engagement with the locking structure of the collar. The collar (30) may thereafter be removed from the vial to facilitate separate disposal of those components.
