Abstract

A resealable vial connector assembly includes a transfer set having a body dimensioned for slidable insertion into a vial. The body includes an axial passageway for fluid communication into or out of the vial. A stopper support extends downwardly from the body and is dimensioned for receiving spaced apart upper and lower vial stoppers. The stopper support includes at least one passageway communicating with the axial space between the stoppers and with the passageway through the body. Upper portions of the transfer set are configured for threaded engagement with a luer collar of a medical fluid delivery instrument such as a hypodermic syringe or intravenous bag. The transfer set is configured for releasable locking engagement with the vial in a first position where both stoppers seal the entrance to the vial and in a second position where the lower stopper permits fluid communication between the vial and the passageway through the transfer set.

12. The connector assembly of claim 1, wherein said upper and lower positions of said transfer set are defined by a selected distance of movement, said upper stopper including an outer circumferential surface having at least one annular rib formed thereon.

13. The connector assembly of claim 1, wherein said upper and lower positions of said transfer set are defined by a selected distance of movement, said upper stopper including an outer circumferential surface having at least one pair of annular ribs formed thereon, said annular ribs being spaced from one another by a distance greater than said selected distance of movement of said transfer set between said upper and lower positions on said vial.

14. The connector assembly of claim 1, wherein said transfer set includes a flange projecting outwardly from said top end of said body, said one or more legs projecting from said flange in spaced relationship to said body, wherein at least one of said legs includes a gripper spaced from said flange and being dimensioned for gripping said annular rim of said vial when said transfer set is in said upper position.

15. The connector assembly of claim 14, wherein said manually deflectable clip is disposed intermediate said gripper of said at least one leg and said flange, said clip configured for releasably locking said annular rim of said vial between said gripper and said clip when said transfer set is in said upper position, and being configured for releasably locking said annular rim of said vial between said clip and said flange when said transfer set is in said lower position.

16. The connector assembly of claim 1, wherein said transfer set is unitarily formed from a thermoplastic material.

17. The connector assembly of claim 1, wherein said body of said transfer set includes a generally annular hollow chamber extending upwardly into said bottom end for accommodating aerosol or gaseous dispersion from said vial.

18. A connector assembly for a vial having an interior, a neck defining an open top to said vial and an externally threaded annular rim around portions of said neck surrounding said open top, said connector assembly comprising:

a transfer set having a body with opposed top and bottom ends, at least said bottom end being dimensioned for slidable movement between upper and lower positions in said open top of said vial, a fluid access device extending from said top end of said body and a stopper support extending from said bottom end, a passageway extending through said transfer set from said fluid access device to an opening located on said stopper support, a generally cylindrical skirt supported in spaced relationship around said body, said skirt including an array of internal threads threadedly engageable with said threads on said annular rim of said vial, said threads extending axially a sufficient distance for moving said body between said upper and lower positions in said open top of said vial; and
