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.
Claims20
A drug delivery device comprising:
- a mechanical audible indicator configured to produce an audible signal with a volume of at least 100 dB, the mechanical audible indicator comprising a resilient force member having a first stable state in which the resilient force member stores mechanical energy and a second stable state in which the resilient force member has deformed and the mechanical energy has been released,
- wherein the mechanical audible indicator is configured to produce the audible signal with the volume of at least 100 dB when the resilient force member transitions from the first stable state to the second stable state.
A drug delivery device comprising:
- a mechanical audible indicator configured to produce an audible signal with a volume of at least 100 dB,
- wherein the mechanical audible indicator comprises a resilient force member configured to reside in two or more states, each state 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 stored energy that is stored by deflecting the resilient force member to generate the audible signal when the resilient force member transitions from the biased state into the relaxed state due to a transition from the second conformation to the first conformation, and
- wherein the audible signal is generated without the resilient force member hitting a component of the drug delivery device.
