Injection Device

An injection device for administering a dose of a liquid medicament comprising:

• a syringe carrier configured to hold a syringe, the syringe containing the dose of the liquid medicament and comprising a stopper movably disposed within the syringe;
• a plunger movable within the syringe carrier and configured to connect to the stopper of the syringe to dispense the dose of the liquid medicament;
• and
• a noise release mechanism comprising
• a releasable noise component comprising a ramped portion, the noise component being configured to generate an audible and/or tactile feedback upon contacting a component of the injection device after release;
• and
• a resilient arm comprising a ramped boss configured to engage the ramped portion of the noise component to inhibit the release of the noise component, the resilient arm being configured to deflect when the plunger is moved past the resilient arm such that the ramped boss disengages from the ramped portion to enable the release of the noise component.

An injection device for administering a dose of a liquid medicament comprising:

• a plunger connectable to a stopper of a syringe and translatable in at least a proximal direction to displace the stopper of the syringe in the proximal direction and
• a releasable noise component capable of upon release, generating an audible and/or tactile feedback,
• wherein proximal displacement of the stopper of the syringe causes the dose of the medicament to be expelled through a hollow injection needle of the syringe, and the noise component is released when the plunger reaches a position relative to the syringe in which the stopper of the syringe is located in proximity of a proximal end of the syringe, and
• wherein the released noise component impacts on at least one component of the injection device to generate the audible and/or tactile feedback indicating an end of an injection,
• wherein the component of the injection device comprises at least part of a trigger button.
