1. A wearable automatic injection device operable without electrical power for administering a therapeutic agent to a patient, the wearable automatic injection device comprising:
- a housing comprising a patient contact portion for contacting the patient;
an administration assembly moveably disposed in the housing holding an administration interface for administering the therapeutic agent to the patient, the administration assembly moveable between a retracted position in which the administration interface does not protrude outside the housing and an extended position in which the administration interface protrudes outside the housing;
a vessel provided in the housing for holding the therapeutic agent;
a plunger actuation mechanism moveably disposed in the vessel for ejecting the therapeutic agent from the vessel into the administration assembly; and
an administration interface locking mechanism for automatically locking the administration interface in the retracted position within the housing in a pre-administration state and a post-administration state.
