1. A wearable infusion device comprising:
- a reservoir that holds a liquid medicament;
an outlet port that delivers the liquid medicament to a patient;
a pump that displaces a volume of the liquid medicament to the outlet port when actuated;
a mechanical control that mechanically actuates the pump; and
a lock-out that acts directly on the mechanical control to preclude operation of the mechanical control when a predefined amount of medicament has been delivered to the outlet.
