Abstract: An administration system for delivery of a pharmaceutical composition to a patient has a delivery device configured to deliver a dose of the pharmaceutical composition to the patient and a notification device in communication with the delivery device. The notification device is configured to communicate information about a status of at least one property of the delivery device. The delivery device can be a wearable automatic injector configured to be worn on the patient's skin. The delivery device of the present disclosure may allow a user or the patient to view a status of a container. For example, the delivery device of the present disclosure may provide a simple and effective visual means of displaying fill confirmation and delivery confirmation.

Abstract: A locking device is disclosed, comprising a locking mechanism having a locked position and an unlocked position, a hollow plunger member having a central axis, the hollow plunger member being engaged with the locking mechanism to move the locking mechanism alternatively into the locked and unlocked positions upon reciprocating linear motion of the hollow plunger member in first and second directions along its central axis, and a motor having a shaft disposed coaxial with the central axis of the hollow plunger member is disclosed. In one embodiment, the locking device further comprises a spring having first and second ends, the first end being fixed to the motor shaft, and a pin fixed to the hollow plunger member for engaging the second end of the spring such that when the motor shaft rotates in a third direction the hollow plunger member moves in the first direction and when the motor shaft rotates in a fourth direction the hollow plunger member moves in the second direction.
