Abstract:
1. An activation member for use with an automatic medicament delivery device, the activation member comprising; a main body configured to extend from a front proximal end to a back distal end; a tubular portion provided near the front proximal end of the main body of the activation member; at least two elongated arms extending away from a distal end of the tubular portion of the main body; at least one guiding element provided along at least one of the at least two elongated arms; a signal generating member coupled to the main body and comprising a distal end wall, wherein the distal end wall comprises a protrusion; such that during an initial, non-activated state of the automatic medicament delivery device, the activation member resides in a first proximal position, and during an activated state of the automatic medicament delivery device, the at least one guiding element is configured to allow the activation member to move longitudinally from the first proximal position to a first distal position while the activation member is biased under a force of a resilient member, wherein after the activated state of the automatic medicament delivery device, the at least one guiding element is configured to guide the activation member into a locked position such that the distal end wall abuts an opening at the distal end of the automatic medicament delivery device and the protrusion extends distally through the opening by a predetermined distance.
