The improved vial transfer assembly or vial transferset may be attached to a vial under sterile conditions and used to transfer fluid to or from a conventional vial. The transferset includes a tubular transfer member which is sealingly supported on the rim portion of a vial stopper, a piercing member having a piercing end reciprocally supported by an internal surface of the transfer member, a cap enclosing the tubular transfer member and a collar preferably formed of a malleable material which secures the assembly on the stopper, which is crimped beneath the vial rim. The piercing member has a generally longitudinal external channel which, upon piercing the planar portion of the stopper, establishes fluid communication with the vial through the tubular transfer member. The distal end of the tubular transfer member includes a Luer lock for establishing fluid communication to a syringe, IV set or the like. An annular lip on the proximate end of the tubular transfer member stretches and prestresses the central portion of the planar stopper rim and the piercing member is supported in the transferset such that the piercing end deforms the prestressed stopper rim portion.

[ What is claimed is:] [1.] A fluid transfer assembly for establishing fluid communication between a syringe or the like and a sealed vial, said vial having an open end, a rim surrounding said open end, a reduced diameter neck portion adjacent said rim and a pierceable stopper received in and sealing said vial open end, said stopper having a rim portion received over said vial rim, said transfer assembly comprising:a tubular transfer member having an open proximate end sealingly supported on said stopper rim portion in alignment with said vial open end and an open distal end adapted to receive a syringe tip in sealed communication;a piercing member received within said tubular transfer member reciprocally supported by an internal surface of said transfer member, said piercing member having a piercing end opposite said stopper rim portion adapted to pierce said stopper and an opposed distal end;a cap having a proximate radial rim portion adjacent an open end, a tubular portion surrounding said tubular transfer member and a closed distal end enclosing said open distal end of said transfer member and said distal end of said piercing member;a collar having a radial portion received over said cap radial rim portion, a tubular portion surrounding said cap radial rim portion and said vial rim and a distal radial portion received in said vial neck portion of said vial beneath said vial rim permanently securing said transfer assembly to said vial, andsaid cap having a frangible portion located beneath said collar spaced from said closed distal end portion of said cap.
