Drug access assembly for vials and ampules

摘要

A vial access pin has a cannula mountable directly to a hypodermic syringe (50) and with a sharp distal end (18). An aperture extends through the cannula wall to the lumen, and proximally of this there is an outward radial flange wider than the mounting. The aperture may be circular and spaced from the distal end, or may be a slot (42) extending from the distal end to a point intermediate the cannula ends. The slot width is pref. less than cannula i.d. The pin is pref. a unitary thermoplastic moulding.
