  • Patent number: 11369744
    Abstract: An audible indicator for use with a drug delivery device is described. The audible indicator includes a spring element configured to reside in one of a relaxed state or a biased state. The audible indicator includes a rotatable element coupled to the spring element. The spring element releases stored energy to rotate the rotatable element such that the rotatable element impacts a surface to generate an audible signal when the spring element changes from the biased state into the relaxed state.

  • Patent number: 11369750
    Abstract: An autoinjector includes a case adapted to hold a medicament container, a needle shroud telescopically coupled to the case, and a plunger slidably disposed in the case. The needle shroud is movable between a first extended position, a retracted position, and a second extended position relative to the case. The plunger is movable between a proximal position, an intermediate position, and a distal position relative to the case. When the plunger is in the intermediate position and the needle shroud is in the retracted position, the plunger abuts the case to prevent the needle shroud from returning to the extended position. When the plunger is in the distal position and the needle shroud is in the second extended position, the plunger abuts the case to prevent the needle shroud from returning to the retracted position.
