摘要：
A drug delivery device includes a housing defining a shell having a proximal and a distal end, a needle assembly at least partially disposed within the housing at the proximal end, a drive assembly at least partially disposed within the housing, and a damper mechanism at least partially disposed within the housing adjacent to the distal end. The housing further defines a longitudinal axis extending between the proximal end and the distal end. The needle assembly includes a syringe barrel containing a medicament and a needle or a cannula. The drive assembly is operably coupled to the needle assembly to urge the medicament through the needle or cannula. The damper mechanism is operably coupled to the drive assembly and the housing. Upon activating the drive assembly, the damper mechanism dampens an effect thereof.
