1. A dual vial adapter assemblage for use with a drug vial and a liquid vial, the drug vial having a drug vial bottle and a drug vial stopper sealing the drug vial bottle containing a medicament, the liquid vial having a liquid vial bottle and a liquid vial stopper sealing the liquid vial bottle containing liquid contents for forming a liquid drug from the medicament in the drug vial, the dual vial adapter assemblage comprising:

  • (a) a drug vial adapter having a longitudinal drug vial adapter centerline and including a transverse drug vial adapter top wall with an upright female connector and an opposite downward depending drug vial adapter skirt with a snap fit flex member pair resiliently flexible at said transverse drug vial adapter top wall and having an inward directed protrusion pair for telescopic snap fit mounting on the drug vial;

    (b) a liquid vial adapter having a longitudinal liquid vial adapter centerline co-axial with said longitudinal drug vial adapter centerline on an initial sealed releasable inter-engagement with said drug vial adapter, said liquid vial adapter including a transverse liquid vial adapter top wall, a liquid vial adapter skirt for telescopic mounting on the liquid vial and a liquid vial stopper puncturing cannula for puncturing the liquid vial stopper on said telescopic mounting said liquid vial adapter on the liquid vial; and

    (c) a drug vial stopper puncturing cannula for puncturing the drug vial stopper on said telescopic snap fit mounting said drug vial adapter on the drug vial, said drug vial stopper puncturing cannula being in flow communication with said liquid vial stopper puncturing cannula in said initial sealed releasable inter-engagement of said liquid vial adapter and said drug vial adapter,characterized in that said drug vial adapter is a quick release drug vial adapter further including an upright finger grip extension pair oppositely extending to said snap fit flex member pair for manual inward urging towards one another for selectively pivoting said snap fit flex member pair at said transverse drug vial adapter top wall for outwardly urging their said inward directed protrusion pair away from said longitudinal drug vial adapter centerline for facilitating release of said drug vial adapter from the drug vial thereby exposing the drug vial stopper,said upright finger grip extension pair facing said liquid vial adapter skirt in said initial sealed releasable inter-engagement of said liquid vial adapter and said drug vial adapter and being sufficiently close to said liquid vial adapter skirt such that said liquid vial adapter skirt prevents said manual inward urging of said upright finger grip extension pair towards one another to release said drug vial adapter from the drug vial.
