1. A disposable wearable infusion device comprising:

  • a reservoir that holds a liquid medicament;

    a cannula having a distal end that delivers the liquid medicament to a patient;

    a pump that displaces a volume of the liquid medicament along a path to the distal end of the cannula when actuated; and

    a lock-out that mechanically and immediately precludes actuation of the pump in response to an occlusion within the path to the distal end of the cannula.
