Abstract

An injection device incorporating a dose setting mechanism is presented where the dose setting mechanism contains a fail safe feature that activates during an interrupted dose delivery event. A dose selector having a projecting rib engages a protrusion on a snap element to prevent the dose knob from moving distally if a user removes an axial force in the proximal direction during dose delivery. The dose setting mechanism can further include a reuse prevention feature.
