Title: FEEDBACK MECHANISM FOR AN INJECTION DEVICE
Abstract:
The present invention relates to a feedback mechanism (20) for an injection device that is configured to deliver a medicament to a user. The feedback mechanism (20) has a biasing member that is arranged to apply a force to a delay element (30), and the delay element (30) is configured to deform and/or break under the force. The feedback mechanism (20) also includes an indicator (24) arranged to generate user feedback after the delay element (30) is deformed and/or broken. The delay element (30) is configured to deform and/or break at a time after the force is applied by the biasing member to create a delay before the user feedback is generated.
