Abstract
Some injection devices include an injection device body, a needle shroud retractable into the injection device body, a control spring coupled to the needle shroud and biased to cause the needle shroud to be at least partially extended from the injection device body in an initial position, and a hold detent mechanism coupled to at least the needle shroud. The hold detent mechanism is configured to (i) activate, when the needle shroud is retracted from the initial position into the injection device body to a hold position, to create a hold detent force, and (ii) deactivate, when the needle shroud is extracted from the hold position subsequent to the retraction, to release the hold detent force and enable the needle shroud to extend from the injection device body to substantially the initial position.
