DRUG DELIVERY DEVICE HAVING DOSE INDICATOR

Abstract:

A drug delivery device includes a housing defining a shell having a proximal end and a distal end and a longitudinal axis extending between the proximal end and the 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 operably coupled to the needle assembly, and an audible indicator operably coupled to the drive assembly. The needle assembly includes a syringe containing a medicament and a needle or a cannula. The drive assembly is movable between an initial position and a second position that results in the medicament being expelled from the syringe. Upon the drive assembly being positioned in the second position, the audible indicator engages the drive assembly to generate an audible sound indicating the medicament has been expelled from the syringe.
