Abstract: Apparatus for mixing liquid with material stored in a container having an opening sealed by a resilient plug includes an adapter having a bore extending through it. The bore is shaped at one end to receive the container plug facing toward the other end of the bore. A first fitting having a passageway extending through it is secured to the adapter at the said other end of the bore. An elongated cannula is sealed at one end to the first fitting passageway so the other end of the cannula penetrates the plug as the container is inserted into the adapter to provide a flow path from the material to the passageway in the first fitting, which is shaped to make a releasable fluidtight seal with a second fitting having a passageway extending through it and adapted to be connected to means for connecting the second fitting passageway to a source of liquid with means for causing the liquid to flow into the container and mix with the material stored in it.

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.
