Abstract
An autoinjector device is provided. The autoinjector device can include an activator unit including an activation housing, an activation guard, and an activation shell such that a portion of the activation guard extends beyond a proximal end of the activation shell. The autoinjector device can include camouflage on a proximal surface to obscure a device lock hole and reduce user confusion around needle orientation.

An autoinjection device comprising:
- an injection unit defining a distal end of the autoinjection device;
- and
- an activator unit defining a proximal end of the autoinjection device, the activator unit comprising:
- an activation housing;
- an activation engine positioned within an interior area of the activation housing, the activation engine including a spring, a piston, and a retaining element, wherein the retaining element is configured to receive a portion of the piston within a distal end thereof;
- an activation guard at least partially surrounding the activation housing such that a portion of the activation housing is positioned within an interior area of the activation guard, wherein the activation guard includes at least one guard member that extends beyond a proximal end of the activation housing;
- an activation shell at least partially surrounding the activation guard such that a portion of the activation guard is positioned within an interior area of the activation shell, wherein the at least one guard member of the activation guard is extended beyond a proximal end of the activation shell;
- and
- a device lock positioned on a proximal end of the activator unit, the device lock including a locking mechanism configured to be positioned within a proximal end of the retaining element of the activation engine when the autoinjection device is in a storage position.
