Abstract
A pen needle () for a delivery device includes a hub () supporting a needle () and a distal needle shield () that can retract to expose the needle during injection and return to the extended position after use and lock in the extended position to cover the needle. A proximal needle shield () moves from a retracted position to an extended position with respect to the hub to shield or cover a proximal end of the needle when the needle hub is separated from the delivery device. A spring () extends between the distal needle shield and the proximal needle shield to bias each needle shield to the respective extended position. The distal needle shield () is coupled to the proximal needle shield () in an initial position to retain the spring () in a compressed state. The distal needle shield () is depressed to disengage the distal needle shield from the proximal needle shield () so that the spring expands to an extended state and moves the shields to the extended positions. A locking member () can be provided to lock the proximal needle shield () and distal needle shield () in the extended position.
