Embodiment Construction

[0019] figure 1 The drug delivery set 5 is shown comprising an initially empty needle-free syringe 10 , a drug vial 20 , a fluid vial 30 , an infusion set 40 (shown on a reduced scale), and a dual vial adapter assembly 100 . Needle-free injector 10 includes barrel 11 , plunger 12 and male Luer lock connector 13 . The syringe 10 can be molded with other types of female connectors. The vial 20 has a longitudinal vial axis 20A and includes an open topped drug vial body 21 having a drug vial crown 22 and a narrow bore drug vial neck 23 . Vial crown 22 is sealed by vial stopper 24 . The vial stopper 24 is sealed by an aluminum band 26 . Vial 20 contains medication 27 in powder, solid or liquid form. Liquid bottle 30 has a longitudinal liquid bottle axis 30A and includes an uncapped liquid bottle body 31 having a liquid crown 32 and a narrow neck medicine bottle neck 33 . The liquid crown 32 is sealed by a liquid cork 34 which is sealed by an aluminum strip 36 . Liquid bottle...

Abstract

Dual vial adapter assemblages having a triple component construction as follows: a first vented female vial adapter for telescopic mounting on a drug vial, a second vented female vial adapter for telescopic mounting on a liquid vial and a tubular liquid transfer coupler for coupling the first vented female vial adapter and the second vented female vial adapter for establishing a dual sealed lumenarrangement therebetween. The dual sealed lumen arrangement includes a central sealed liquid lumen for gravitational flow of liquid contents from a liquid vial to a drug vial and a sealed air lumen radial outward from the central sealed liquid lumen for venting air displaced from the drug vial to the liquid vial for assisting the gravitational flow of liquid contents by creating a closed system between the liquid vial and the drug vial.

Description

technical field [0001] The present invention relates to a dual vial adapter assembly for a vial containing a drug and a vial containing a liquid component. Background technique [0002] Dual vial adapter assembly for use with vials containing medication and liquid vials containing liquid ingredients instruments to mix or reconstitute with the medication in the vial to form a liquid medication, the dual vial adapter assembly includes a vial adapter and a liquid vial adapter , the medicine bottle adapter is used for telescopic installation on the medicine bottle to puncture the medicine bottle, and the liquid bottle adapter is used for telescopic installation on the liquid bottle for puncturing the liquid bottle. Two-bottle adapter assemblies can be broadly classified into the following two categories: Negative pressure type, which is used with a medicine bottle under negative pressure to positively draw the liquid components in the liquid bottle into the medicine bottle. Gra...
