Abstract
A feedback mechanism for an injection device that is configured to deliver a medicament to a user is described. The feedback mechanism comprises an actuator and a fluid chamber having a restricted outlet. The actuator is adapted to urge fluid from the fluid chamber through the restricted outlet. The feedback mechanism also has an indicator that is adapted to provide feedback to the user after a predetermined volume of fluid has passed from the fluid chamber through the restricted outlet during use of the injection device.
