Abstract
An injection device () for the delivery of medicament has an indicator () for providing an end of dose indication. The device comprises a housing (), an extendable plunger (), an actuation mechanism (), a trigger arrangement (), and an indicator (). The extendable plunger () comprises a leading portion () and a trailing portion () configured to allow the plunger () to extend from an initial length to a maximum extended length, the plunger portions ((),) being slidably mounted within the housing (). The actuation mechanism () is configured to move the leading portion () of the plunger () forwardly relative to a syringe () so as to express medicament from the syringe (). The trigger arrangement () is moveable in use to release the actuation mechanism (). The indicator () is responsive to the forward movement of the plunger () and is configured to provide an audible and/or tactile and/or visual indication of the end of dose when the plunger () reaches or approaches its forwardmost position.
