Abstract:
1. A medical device for use with a fluid transfer device having a frusto-conically shaped tip comprising: a hub having an open proximal end with a frusto-conically shaped cavity therein, a distal end and a passageway therethrough, said cavity being part of said passageway; and a release element in said passageway of said hub positioned to block fluid-tight engagement of said frusto-conically shaped tip with said cavity of said hub, said release element including a proximal end and a distal end capable of telescoping action with respect to each other; and at least one frangible link between said proximal end and said distal end of said release element, said link being breakable upon application of a proximally directed force on said hub so that said proximal and distal ends of said release element can telescope with respect to each other and allow engagement of said tip, to allow the abrupt fluid-tight engagement of said tip and said cavity in said hub and to release at least part of said release element.
