First Claim
1. A liquid drug transfer device for use with a drug vial of a small drug vial and a large drug vial, the drug vial including a drug vial bottle, a drug vial interior, a drug vial stopper, an uppermost drug vial surface, and a drug vial closure,the small drug vial having a drug vial closure with an external diameter D1 and the large drug vial having a drug vial closure with an external diameter D2 where D2>
- D1 and the difference D2−
D1 is in the range of between 4 mm and 7 mm,the liquid drug transfer device comprising an universal drug vial adapter having a longitudinal drug vial adapter axis and a skirt for telescopically clamping on the drug vial closure,said skirt including a top wall transverse to said longitudinal drug vial adapter axis, a first pair of axial directed, spaced apart flex member supports and a second pair of axial directed, spaced apart flex member supports opposite said first pair of axial directed flex member supports for defining a drug vial cavity for snugly telescopically receiving at least a top part of a large drug vial therein,each flex member support having a proximate end adjacent said top wall and a distal end remote from said top wall,said first pair of flex member supports including a first crosspiece extending between their corresponding distal ends, said first crosspiece integrally formed with an axial directed first flex member resiliently flexibly mounted thereon with respect to said longitudinal drug vial adapter axis, said first flex member having a first flex member free end remote from said first crosspiece and being axially directed and extending generally parallel to said longitudinal drug vial adapter axis from said first crosspiece to said first flex member free end, said first flex member further having an inward radial directed first drug vial grip,said second pair of flex member supports including a second crosspiece extending between their corresponding distal ends, said second crosspiece integrally formed with an axial directed second flex member resiliently flexibly mounted thereon with respect to said longitudinal drug vial adapter axis, said second flex member having a second flex member free end remote from said crosspiece and being axially directed and extending generally parallel to said longitudinal drug vial adapter axis from said second crosspiece to said second flex member free end, said second flex member further having an inward radial directed second drug vial grip,said first flex member and said second flex member being opposite such that said first drug vial grip and said second drug vial grip define a separation S therebetween where S<
D1 whereupon said first drug vial grip and said second drug vial grip underlie a drug vial closure on telescopically clamping said universal drug vial adapter on the drug vial,said first flex member and said second flex member being outwardly resiliently flexed correspondingly at said first crosspiece and said second crosspiece with respect to said longitudinal drug vial adapter axis to a greater extent on telescopically clamping said universal drug vial adapter on the large drug vial compared to telescopically clamping said universal drug vial adapter on the small drug vial.

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.
