Abstract
The disclosure relates to a drug delivery device, comprising a mechanical audible indicator capable of producing an audible signal with a volume of at least 100 dB.
Claims24
A drug delivery device comprising:
- a mechanical audible indicator configured to produce an audible signal with a volume of at least 100 dB(A);
- wherein the mechanical audible indicator consists of one or more mechanical components configured such that the volume is at least 100 dB(A) at a distance of 150 mm,
- wherein a mechanical component of the one or more mechanical components is a resilient force member,
- wherein the resilient force member is supported in a biased state by an element of the drug delivery device to prevent transition into a relaxed state, and
- wherein the element of the drug delivery device comprises a flexible arm.

A drug delivery device comprising:
- a mechanical audible indicator configured to produce an audible signal with a volume of at least 100 dB(A);
- wherein the mechanical audible indicator consists of one or more mechanical components,
- wherein a mechanical component of the one or more mechanical components is a resilient force member,
- wherein the resilient force member is configured to reside in two or more states, each of the two or more states having a respective conformation,
- wherein, in a relaxed state, the resilient force member is relaxed in a first conformation,
- wherein, in a biased state, the resilient force member is biased to store energy in a second conformation different than the first conformation,
- wherein the resilient force member is configured to release the stored energy that is stored by deflecting the resilient force member to generate the audible signal when changing form the biased state into the relaxed state due to a transition from the second conformation to the first conformation, and
- wherein the resilient force member includes a leaf spring having a longitudinal axis, wherein the resilient force member is bent by a certain angle about the longitudinal axis to form two angled wing-shaped sections.
