Beschreibung
Zusammenfassung:	A pen needle assembly (10) includes a pen needle (12) with a hub body (16) having a needle shield (28) that covers a needle (26) and can be retracted to expose the needle during injection and return to the extended position after use and locked in the extended position. A spring (56) is provided to rotate the needle shield after use to a locked position. A locking member (84) can be provided on the needle shield that cooperates with the hub body (16) to prevent rotation after use. An attachment mechanism (38) for the pen needle provides a sensory indication when a needle-bearing hub body (16) is seated on a pen and limits further rotation of the pen needle relative to the delivery device.
