A drug vial adapter according to the invention includes: a first coupling member having a female luer connector (preferably a luer lock) with a fluid path therethrough, a flange having a first sealing ring seat formed therein and a first mating structure; a second cylindrical coupling member having a centrally located septum piercing tube with a fluid path therethrough and a second mating structure; and a valve member including a valve stem and a resilient valve body having an annular sealing surface. A valve body seat is formed in the interior of the second coupling member by a plurality of radially arranged stepped vanes. According to a preferred embodiment, the second coupling member is formed as a stepped cylinder having a relatively large diameter adjacent the point of the septum piercing tube, a relatively small diameter adjacent the valve body seat and an intermediate diameter therebetween. The presently preferred valve body is substantially frustroconical having a relatively broad end with a stepped axial bore defining the annular sealing surface. The presently preferred valve stem has a stepped cylindrical portion which fits into the axial bore of the valve body and a pair of spaced apart upstanding members which extend into the female luer.

[ I claim:] [1.] A vial adapter for use with a vial having a pierceable septum, said vial adapter comprising:a) a first coupling member having a female luer at a first end of said first coupling member, and a first mating structure;b) a valve member having a stem and a resilient body with a sealing

[ I claim:] [1.] A vial adapter for use with a vial having a pierceable septum, said vial adapter comprising:a) a first coupling member having a female luer at a first end of said first coupling member, and a first mating structure;b) a valve member having a stem and a resilient body with a sealing surface, said valve member disposed relative to said first coupling member with said stem extending into said female luer; andc) a second coupling member having a first open generally cylindrical chamber with a valve member support, a septum piercing member in fluid communication with said first cylindrical chamber, and a second mating structure for mating and coupling with said first mating structure, said second coupling member being coupled to said first coupling member with said valve member support supporting said resilient body of said valve member such that said sealing surface is biased against said female luer thereby blocking fluid communication between said female luer and said first cylindrical chamber.
