Abstract: A pen needle (10) includes a hub (34) supporting a needle (28) and a distal needle shield (14) that can retract to expose the needle during injection and return to the extended position after use and locked in the extended position cover the needle. A proximal needle shield (16) moves to an extended position with respect to the hub (34) to cover a proximal end (34) of the needle. A spring (64) extends between the distal needle shield (14) and the proximal needle shield (16) to bias each needle shield to the respective extended position. A locking member (78) on the distal needle shield cooperates with the hub to lock the needle shields in the extended position. An indicator (94) in the hub engages and couples to the distal needle shield (14) when moved to the retracted position. The indicator (94) moves with the distal needle shield (14) to the extended position where the indicator is visible through the distal needle shield (14) indicating that the pen needle is no longer usable.

Abstract: A package (116) for a medical cannula, including a plurality of medical cannula outer shields (29), the outer shields each being configured for receiving a medical cannula therein. The package also includes a web (100) having a plurality of holes (104) therethrough corresponding to the plurality of outer shields. Each of the corresponding plurality of holes retains one of the plurality of medical cannula outer shields therein.
