Transfer devices liquid drugs for proper snap failsafe in medicinal vials.

摘要

Device (10) for transferring liquid drugs for proper snap fitting failsafe a medicinal vial (11) having a longitudinal axis (12) and including a portion (13) bottle containing a medicament, a opening (16) of vial with a flange and an axially directed and covered by a cap (18) and an intermediate tapered neck (17) between the bottle portion and the vial opening peripheral surface, the transfer device comprising liquid drugs: (a) an adapter (30) vial having a longitudinal axis (31) and including an upper transverse wall (33) relative to said longitudinal axis, a jacket (34) substantially cylindrical at least four flexible members axially directed and resiliently flexibly connected to said top wall shape and facing downward therefrom for slidably telescopically so the vial opening therein and a syringe perfo hollow radora (38) for perforating the stopper, said puncturing spike a tip with at least one flow opening for accessing the interior of the vial, including said at least four flexible members, at least two flexible members (36) vial retention nonadjacent flanged vial retention protruding inward and extending at least partially circumferentially for a press fit over the vial opening for retention of the vial and at least two flexible members (37) of guide longer nonadjacent vials said at least two flexible retaining members nonadjacent vials relative to said top wall to simultaneously contacting the flange of the vial opening to align said vial adapter to the vial before the adjustment pressure; and (b) at least one access port in fluid communication with said puncturing spike, characterized in that said at least two flexible guide members nonadjacent vials are not used for purposes vial retention.
