<p>A disposable plastic adaptor connects a medicine vial to a needleless injector. It includes a hollow, generally cylindrical body member having a top end and a bottom end, with a wall dividing said hollow body into a generally cylindrical top end cavity and bottom end cavity. The bottom end cavity is adapted to slide over the top end of a medicine vial and the cavity wall includes a plurality of detents which prevent removal of the adaptor from the vial. The top end cavity is adapted to be twist connected to the end of a needleless injector. A fluid connector member is mounted within the body member and it comprises a sharp tipped probe extending axially downwardly within the bottom end cavity and an axial projection with a concave end face extending axially upwardly within the top end cavity. An axial bore extends through the fluid connector member to flow connect the concave end face and the probe tip. This probe, preferably in the form of a hollow needle, is adapted to penetrate the top of a medicine vial and the concave end face is adapted to provide a fluid tight seal with a convex end face of a cylindrical medicine syringe within the needleless injector.</p> |
