An injection system, including an injector having a dispensing mechanism configured to dispense a medicament, and a ready-to-use indicator. The ready-to-use indicator includes a controller configured to interact with the ready-to-use indicator and an audio and/or visual indicator, a temperature sensor, and a temperature analog having similar thermodynamic properties of the medicament. The temperature sensor is configured to detect a temperature of the temperature analog which represents the dynamic temperature of medicament as the medicament is heated or cooled. The temperature sensor is configured to communicate the detected temperature to the controller and to alert the controller when a preset temperature is reached. The ready-to-use indicator is configured to alert a user when the preset temperature is reached, signifying the medicament is thermally ready to be delivered by the dispensing mechanism. The audio and/or visual indicator is configured to display indicate one or more notifications to the user.

Injector with ready to use indicator

A telescopic screw assembly for an injector includes an inner screw, an outer screw and a middle screw. The middle and outer screws are in a first threaded engagement, and the inner and middle screws are in a second threaded engagement. The inner screw is nested with the middle screw and the middle screw is nested with the outer screw in a contracted configuration of the screw assembly. Rotation of the outer screw in one direction advances the middle screw relative to the outer screw via the first threaded engagement and advances the inner screw relative to the middle screw via the second threaded engagement to telescopically extend the screw assembly into an expanded configuration. At least two of the inner, middle and outer screws are identified with a different visual indicator to enhance visual distinction between the screws, and readily visually indicate an extension progress of the screw assembly.

Staged telescopic screw assembly having different visual indicators

A compliance monitoring system is provided for an injection device having an unused state and a used state. The system includes one or more radio frequency tags attached to a surface of the injection device and a portable monitoring accessory that includes a housing, a radio frequency antenna disposed within the housing, a wireless transmitter module disposed within the housing, and a processing circuit disposed within the housing. The processing circuit is configured to receive, via the radio frequency antenna, a first signal from the one or more radio frequency tags via a radio frequency communication protocol. The processing circuit is also configured to transmit, via the wireless transmitter, a second signal to a mobile device via a wireless communication protocol different from the radio frequency communication protocol. Both of the first signal and the second signal include state information of the injection device.
