摘要： An injection device for administering a dose of a liquid medicament is disclosed. The device includes a syringe containing the dose and a hollow injection needle. The device includes a stopper translatably disposed within the syringe and a plunger connectable to the stopper and translatable in at least a proximal direction to displace the stopper. The device further includes a releasable noise component capable of, upon release, generating an audible and/or tactile feedback. Proximal displacement of the stopper causes the dose to be expelled through the injection needle. The noise component is released when the plunger reaches a position relative to the syringe in which the stopper is located in proximity of a proximal end of the syringe. The released noise component impacts on at least one component of the injection device to generate the audible and/or tactile feedback indicating the end of the injection.

摘要： The invention relates to a detent mechanism for controlling translation between two components in a longitudinal direction (P, D), the detent mechanism comprising at least one clip on one of the components arranged to be in a ramped engagement with a recess in the other one of the components in an initial state in such a manner that translation between the components is constrained and that application of a translative force between the components in one longitudinal direction (P, D) with the clip engaged with the recess deflects the clip out of the recess when a predetermined value of the translative force, at least depending on the resilience of the clip, is overcome so as to allow translation between the components.
