Abstract
An automatic medication injection device (20) including injecting progress indicators (82-85) visible along a periphery of the device housing (23). The injecting progress indicators include a flag element (100) which is movable as a drive mechanism (60) of the device advances a sealing plunger (58) within a container of medication (50). The injecting progress indicators are configured to indicate sequentially during a single injection as the flag element moves to cooperatively complete different injecting progress indicators at different times during the single injection, whereby injecting progress of the injection may be monitored by a user.
Claims14
An automatic medication injection device comprising:
- a user grippable housing having a length extending in an axial direction between a proximal end and a distal end;
- a container of medication including an outlet that is disposed proximally of said housing proximal end at least during injection, said container including a barrel and a sealing plunger, said sealing plunger in sealing engagement with said barrel;
- a drive mechanism within said housing which when triggered is configured to automatically advance said sealing plunger proximally within said container to force medication from the container outlet, said drive mechanism comprising a plunger element being axially movable and non-rotational relative to said housing during injection, said plunger element having a driver portion that extends within said barrel to directly engage said sealing plunger, said plunger element including a proximally extending flag element fixedly coupled thereto, the flag element being in spaced relationship with the plunger element to provide a gap sized to receive a portion of the container;
- and
- a plurality of injecting progress indicators visible along a periphery of the housing, at least one of said plurality of injecting progress indicators located distally of said container during an injection, said injecting progress indicators including the flag element of said plunger element movable as the drive mechanism advances said sealing plunger proximally within said container, said plurality of injecting progress indicators configured to indicate sequentially in an axial direction during a single injection as the flag element moves to cooperatively complete different injecting progress indicators at different times from a start to a finish during the single injection, whereby injecting progress of the single injection may be monitored by a user.
