摘要：
An auto-injector for administering a dose of a liquid medicament includesan elongate case arranged to be held by a user,a tubular chassis telescopable in the case and biased against the case so as to protrude from the case,a syringe with a hollow injection needle, a drive spring and a plunger for forwarding load of the drive spring to a stopper of the syringe, anda trigger button which is initially abutted against the case thus preventing actuation.The chassis is arranged to translate into the case against the bias when pressed against an injection site. The trigger button is initially coupled to the chassis such that the trigger button emerges from the case when the chassis is being pressed against the injection site to allow actuation by being translated towards the case for starting an injection cycle.
