摘要： An Injection device for administering a dose of a liquid medicament to a patient comprises a syringe containing the dose of the medicament a hollow injection needle adapted to penetrate the skin of the patient, a stopper translatably disposed within the syringe, a plunger connectable to the stopper and translatable in at least a proximal direction to displace the stopper in the proximal direction and a releasable noise component capable of, upon release, generating an audible and/or tactile feedback. The proximal displacement of the stopper causes the dose of the medicament to be expelled through the hollow 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.
