Embodiment Construction

[0042] In this application, when the term "distal section / distal end" is used, this refers to the section / end of the device, or a component thereof, that is closest to the patient's drug delivery site when the device is in use. Accordingly, when the term "proximal section / proximal end" is used, this refers to the section / end of the device, or a section / end of a component thereof, that points away from the patient's drug delivery site during use of the device.

[0043] figure 1 An exemplary embodiment of a drug delivery device 1 that can be configured as an auto-injector is shown.

[0044] In this exemplary embodiment, the drug delivery device 1 comprises a housing 2 having a front housing 2.1 and a rear housing 2.2. The housing 2 is adapted to hold a medicament container 3, such as a syringe. (The medicament container is hereinafter referred to as "syringe 3"). The syringe 3 may be a prefilled syringe containing the medicament M and having a needle 4 arranged on the distal ...

Abstract

The present disclosure relates to an audible indicator (13) for a drug delivery device (1), said audible indicator (13) comprising a resilient spring configured to be in one of a relaxed state (S1) and a biased state (S2). a force member (13.1), - wherein said audible indicator (13) comprises a retainer adapted to retain said resilient force member (13.1) in said biased state (S2), - wherein when said When the elastic force member (13.1) changes from the biased state (S2) to the relaxed state (S1), the elastic force member (13.1) releases stored energy to collide with a surface to generate an auditory signal.

Description

technical field [0001] The present disclosure relates to audible indicators for drug delivery devices. Background technique [0002] Administering injections is a process that presents many risks and challenges (mentally and physically) to users and medical professionals. Injection devices generally fall into two categories - manual devices and auto-injectors. In traditional manual devices, manual force is required to drive the drug through the needle. This is usually accomplished by some form of button / plunger that must be continuously pressed during the injection. There are many disadvantages to this approach. For example, if the button / plunger is released prematurely, the injection will stop and the intended dose may not be delivered. Furthermore, the force required to press the button / plunger may be too high (eg, if the user is elderly or small). Also, aligning the injection device, administering the injection, and maintaining the injection device during injection m...
