The patent application (Publication Number: US20240033440A1) describes an injection device designed to deliver a medicament to a user. The device comprises a housing with an inner wall featuring an inclined surface, a cartridge holding the medicament and a piston, and a drive mechanism responsible for moving the piston from a position where the medicament is contained to a position where it is delivered. The unique feature of this device is the inclusion of a flexible portion in the drive mechanism that moves towards the central axis of the device during operation, disengaging from the inclined surface near the end of the delivery process to audibly indicate that the medicament has been successfully administered.
Furthermore, the injection device includes a drive member with a plunger and a drive spring to facilitate the movement of the piston. The plunger incorporates the flexible portion, specifically a flexible finger connected to the plunger that extends outwardly from the central axis of the device. This flexible finger, along with a lateral projection, plays a crucial role in the mechanism's operation. The drive mechanism also includes a spring with a flexible extension that aids in the movement of the piston, ensuring the efficient delivery of the medicament. These design elements work together to provide a reliable and user-friendly injection device for administering medication.
