Sanofi
Autoinjector

Abstract:

An autoinjector includes a case having a rib, a needle shroud telescopically coupled to the case, a carrier slidably arranged in the case and adapted to hold a medicament container, and a collar rotatably and slidably disposed in the case and coupled to the needle shroud and the carrier. The needle shroud is movable between a first extended position, a retracted position and a locked second extended position. The carrier is movable from a first axial position to a second axial position relative to the case. The collar abuts the rib when the needle shroud is in the first extended position and the carrier is in the first axial position, and the collar disengages the rib when the needle shroud is in the retracted position and the carrier is in the second axial position.
