ABSTRACT:
A medication injector for use with an inlet port having an imperforate closure for a conduit connected to and extending away from a container for liquid intended for intravenous administration includes a boss which carries a cannula with a scarf at one end spaced from the boss. The cannula scarf is adapted to puncture the inlet port closure. An elongated and generally cylindrical sheath is secured to the boss and extends around the cannula and extends beyond the scarf end of the cannula. An outwardly extending annular flange on the sheath prevents the cannula from being inserted into an injection port of a Y-site of an intravenous administration set, yet permits the cannula to be inserted into the inlet port of the i.v. container.
