Abstract

Liquid drug transfer devices with universal drug vial adapters for use with a drug vial of a small drug vial and a large drug vial. Some universal drug vial adapters employ the same generally opposite upright flex members for clamping a small drug vial and a large drug vial. Other universal drug vial adapters include a set of minor flex members for clamping a small drug vial and a set of major flex members encircling the set of minor flex members for clamping a large drug vial whereupon the large drug vial underlies the set of minor flex members. Liquid drug transfer devices with a universal injection port connector for attachment on an injection port of an infusion bag.

Claims

1. A liquid drug transfer device for use with an infusion bag containing an infusion liquid and having an injection port, the injection port terminating in an injection port tip containing a self-sealing plug with an exposed plug surface, the injection port tip having a trailing injection port rim,

the liquid drug transfer device comprising an open ended housing having a longitudinal housing axis and including a universal injection port connector,

said universal injection port connector having a longitudinal connector axis co-directional with said longitudinal housing axis and a closed support ring defining a horizontal plane transverse to said longitudinal connector axis,

said support ring having a multitude of curved connector members resiliently flexibly mounted thereon and a free connector member end converging towards a connector aperture underlying said support ring from a direction of said open ended housing such that said universal injection port connector assumes an overall bowl like shape,

the arrangement being such that on forced sliding insertion of the injection port tip through said connector aperture into said open ended housing, the injection port tip outwardly flexes said multitude of connector members from their non-flexed position relative to said connector axis for snapping behind the trailing injection port rim, thereby precluding outward sliding withdrawal of the injection port tip from said open ended housing in a reverse direction to said forced sliding insertion.
