System and method for locking a controlled medical therapy device

A nasal substance dispenser, comprising:

• a housing configured to house a vial of a substance;
• a nozzle configured to be inserted into a nostril of a patient and to dispense;
• an actuator movable between an extended position and a depressed position, wherein movement of the actuator from the extended position to the depressed position causes at least a portion of the substance in the vial to exit the dispenser through the nozzle;
• and
• a sensor configured to determine a position of the actuator between the extended position and the depressed position.

A nasal substance dispenser, comprising:

• a housing comprising a chamber sized to house a vial of a substance;
• a nozzle configured to be inserted into a nostril of a patient and to dispense the substance, the nozzle comprising a housing interface sized to slide into and out of the chamber;
• a first lock configured such that when closed the housing interface is prevented from disengaging from the housing and such that when opened the housing interface is removable from the chamber,
• wherein the vial is removable from the chamber when the housing interface is removed from the chamber and the vial is prevented from being removed from the chamber by the housing interface when the housing interface is engaged to the housing;
• and
• a second lock configured such that when closed movement of the housing interface within the chamber is inhibited to prevent the nozzle from dispensing the substance and such that when opened the housing interface is slidable within the chamber to allow the nozzle to dispense the substance.
