Patent attributes
An injector includes a housing and an activation button assembly movably mounted thereto and translatable from an unactuated position to an actuated position. A cartridge door is configured to receive therein a cartridge containing a substance to be dispensed, and is movably mounted to the injector housing between open and closed positions. A deflectable interference member is mounted within the injector housing and, in a resting position, blocks movement of the activation button assembly from the unactuated to the actuated position thereof. The activation button assembly is configured to activate the injector when in the actuated position, and is movable from the unactuated position to the actuated position solely upon deflection of the interference element out of the resting position thereof. The cartridge door, when in the closed position thereof and having the cartridge received therein, deflects the interference element out of the resting position thereof.
