A fluid transfer adapter (321) for use with a syringe barrel (322) having an ope nproximal end (328) including a collar (331) having adapter engaging structure (334)and a distally-facing frusto-conically shaped surface (335) comprises a h ub (353) having a proximally-facing frusto-conically shaped surface (359) for ma tingwith the frusto-conically shaped surface (335) on the barrel (322), structur e forthreadably engaging the hub to the collar(331) of the barrel (322) so that the frusto-conically shaped surface (359) of the hub (353) contacts the frusto -conically shaped surface(335) of the barrel (322) to prevent liquid flow between the surfaces and a fluid transfer (390) having a passageway therethrough connected to the distal end (356) of the hub (353) so that the lumen (3 94) is in fluid communication with a conduit (357) in the hub (353).
L'invention concerne un adaptateur de transfert de liquide, qui s'utilise avec un cylindre de seringue comportant une extrémité proximale ouverte munie d'un collier présentant une structure d'emboîtement à l'adaptateur, et une surface de forme frusto-conique à orientation distale. L'adaptateur de transfert de liquide comprend un embout présentant une surface de forme frusto-conique à orientation proximale homologue de la surface de forme frusto-conique de la structure du cylindre, qui met en prise de filetage l'embout et le collier du cylindre de sorte que la surface de forme frusto-conique de l'embout vienne au contact de la surface de forme frusto-conique du cylindre pour empêcher l'écoulement du liquide entre les surfaces. L'adaptateur de transfert de liquide comprend en outre un dispositif de transfert de fluide traversé d'un conduit, relié à l'extrémité distale de l'embout de sorte que la lumière communique librement avec un conduit ménagé dans l'embout.
