Medicament identification system for multi-dose injection devices

摘要

A dose setting mechanism for a drug delivery device with a cartridge, comprises a body 35 and a dial sleeve 40 that is operably connected with the body, where the dial sleeve has an outer surface that contains an indicia 42 to identify a medicament and where the indicia is hidden from view when a zero dose is set. At least part of the indicia 42 on the outer surface of the dial sleeve 40 is exposed when a dose greater than zero is set.
