A drug delivery system includes first drug (110) and second diluent (182) syringe assemblies which are respectively pre-filled with a drug concentrate and a liquid diluent. The diluent syringe assembly is positionable in operative association within a sterility maintenance sleeve (150) of the first syringe assembly so that the assemblies are joined in fluid communication. This fluid transfer connection permits the diluent to be transferred from the second syringe assembly into a sterile mixing chamber defined by a reciprocable stopper (134) in the first syringe assembly. Thereafter, the second syringe assembly can be moved with respect to the barrel of the first syringe assembly so that the resulting mixture can be delivered for patient administration. |
