Alternatively, FIG. 4A to FIG. 4D could equally show telescopic mounting of the second vial adapter 120 on the liquid vial 30, the first vial adapter 110 on the drug vial 20, unscrewing the dual ended liquid transfer coupler 130 from the first vial adapter 110 for exposing the female Luer connector 113 and screwing the syringe 10 onto the first vial adapter 110 for aspirating a liquid drug dosage from the drug vial 20 for administration to a patient.

(19) FIG. 5 shows a dual vial adapter assemblage 200 similar in construction and operation as the dual vial adapter assemblage 100. The latter 200 differs from the former 100 insofar as the latter 200 includes a first vial adapter 210 having an upright first vial adapter connector 211 of a first connector type, a second vial adapter 220 having an upright second vial adapter connector 221 of the same first connector type and a dual ended liquid transfer coupler 230 having dual opposite connectors 231 and 232 of the second connector type for corresponding sealing engagement with the first vial adapter connector 211 and the second vial adapter connector 221 in a set-up position of the dual vial adapter assemblage 200. The first connector type is constituted by a male Luer lock connector and the second connector type is constituted by a female Luer connector. The use of the dual vial adapter assemblage 200 is the same as the dual vial adapter assemblage 100 except that the dual ended liquid transfer coupler 230 is left attached to either the first vial adapter 210 or the second vial adapter 220 telescopically mounted on a drug vial 20 containing a liquid drug formed therein.

(20) FIGS. 6 to 8 show a dual vial adapter assemblage 300 of the gravitational flow type for preparing a large liquid drug dosage. The dual vial adapter assemblage 300 includes a first vial adapter 310, a second vial adapter 320 and a dual ended liquid transfer coupler 330 intermediate the first vial adapter 310 and the second vial adapter 320. The first vial adapter 310 and the second vial adapter 320 are preferably of the quick release type as disclosed in PCT International Publication No. WO 2012/150587 entitled Vial Adaptor.

(21) The first vial adapter 310 has a longitudinal first vial adapter centerline 311 and includes a transverse first vial adapter top wall 312 having an upright female Luer connector 313 with an external screw thread for screw thread engagement by a male Luer lock connector. The first vial adapter top wall 312 has an oppositely directed first vial adapter skirt 314 for telescopic mounting on a vial. The first vial adapter top wall 312 includes a dual lumen vial stopper puncturing cannula 316 for puncturing a vial stopper on telescopic mounting of the first vial adapter 310 on a vial. The dual lumen vial stopper puncturing cannula 316 includes a liquid lumen 317 in flow communication with the female Luer connector 313 and a vented air lumen 318 with throughgoing bores 319 formed in the first vial adapter top wall 312. The liquid lumen 317 typically has a wider lumen diameter than the vented air lumen 318. The vial adapter 310 can optionally include an air filter for filtering incoming air.

(22) The second vial adapter 320 has a longitudinal second vial adapter centerline 321 and includes a transverse second vial adapter top wall 322. The second vial adapter top wall 322 has an upright female Luer connector 323 for screw thread engagement by a male Luer lock connector. The second vial adapter top wall 322 has an oppositely directed second vial adapter skirt 324 for telescopic mounting on a vial. The second vial adapter top wall 322 includes a dual lumen vial stopper puncturing cannula 326 for puncturing a vial stopper on telescopic mounting of the second vial adapter 320 on a vial. The dual lumen vial stopper puncturing cannula 326 includes a liquid lumen 327 in flow communication with the female Luer connector 323 and a vented air lumen 328 with throughgoing bores 329 formed in the second vial adapter top wall 322. The liquid lumen 327 typically has a wider lumen diameter than the vented air lumen 328. The vial adapter 320 can optionally include an air filter for filtering incoming air.

(23) The dual ended liquid transfer coupler 330 includes dual opposite male Luer lock connectors 331 and 332 for corresponding sealing engagement with the female Luer connector 313 and the female Luer connector 323 in the set-up position of the dual vial adapter assemblage 300.

(24) FIG. 9 shows the first vial adapter 310 telescopic mounted on the drug vial 20 and the second vial adapter 320 telescopic mounted on the liquid vial 30. Alternatively, the telescopic mounting of the dual vial adapter assemblage 300 on the drug vial 20 and the liquid vial 30 could have been reversed with the first vial adapter 310 telescopic mounted on the liquid vial 30 and the second vial adapter 320 mounted on the drug vial 20. FIG. 9 shows gravitational flow of liquid contents from the liquid vial 30 to the drug vial 20 through the liquid lumen 327, the dual ended liquid transfer coupler 330 and the liquid lumen 317 as denoted by arrows A. FIG. 9 shows the gravitational flow is facilitated by air being drawn into the liquid vial 30 via the vented air lumen 328 denoted by arrows B and air being expelled from the drug vial 20 via the vented air lumen 318 denoted by the arrows C.

(25) The use of dual vial adapter assemblage 300 is similar to the dual vial adapter assemblage 100 except the dual ended liquid transfer coupler 330 is unscrewed from the first vial adapter 310 ready for attachment of the needleless syringe 10 for aspiration of some liquid drug from the drug vial 20. Thereafter, the second vial adapter 310 is removed from the drug vial 20 for exposing the drug vial stopper 24 for administration by an IV infusion set.

(26) FIG. 10 shows a dual vial adapter assemblage 400 similar in construction and operation as the dual vial adapter assemblage 300. The latter 400 differs from the former 300 insofar as the latter 400 include a first vial adapter 410 having a male Luer lock connector 411, a second vial adapter 420 having a male Luer lock connector 421 and a dual ended liquid transfer coupler 430 having dual opposite female Luer connectors 431 and 432 for corresponding sealing engagement with the male Luer lock connector 411 and the male Luer lock connector 421. The use of the dual vial adapter assemblage 400 is the same as the dual vial adapter assemblage 300 except that the dual ended liquid transfer coupler 430 is left attached to either the first vial adapter 410 or the second vial adapter 420 telescopically mounted on a drug vial 20 containing a liquid drug formed therein.

(27) While particular embodiments of the present invention are illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention.
