DISPENSER FOR DELIVERING MEDICAMENT

摘要

A dispenser suitable for biomedical use, comprises: an actuator (22), wherein movement comprising completion of a dispensing stroke of the actuator dispenses a dose of a product; a lock (25) operable in a locked state to limit the actuator movement so as to prevent a dose from being dispensed, wherein the lock has a resilient self -locking mechanism (32) for placing the lock into the locked state after a dose is dispensed and a sensor operable to sense when the lock is in the locked state; a lock actuator (45); and a control circuit (26) responsive to the sensor and operable after a lock-out period determined by the control circuit to energise the lock actuator to return the lock to an unlocked state.
