Patent attributes
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.
