1-16. (canceled)
A state indicator comprising:
- an outer housing structure which is designed for indicating a number of states of a drug delivery device,
- wherein the state indicator is formed as a single indicator indicating at least
- a pre-injection state before an injection,
- an injection state during the injection when the injection is being performed, and
- a post-injection state when the injection is completed, and
- wherein the state indicator is formed as at least one of a visual indicator, an optical indicator, or an electronic indicator.
