摘要： 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.

摘要： An autoinjector that automatically retracts a needle contained therein includes an injection assembly, having a plunger and a movable piston coupled to the plunger, a retraction assembly coupled to the injection assembly, and an end-of-dose visual indicator disposed within the retraction assembly. The retraction assembly includes an opaque section, a transparent or translucent section coupled to the opaque section, and a drug container having a hypodermic needle. The end-of-dose visual indicator is disposed within the retraction assembly such that the indicator moves upwardly from the opaque section of the retraction assembly to the transparent or translucent section of the retraction assembly upon full administration of a drug solution or medicine contained within the drug container. The end-of-dose visual indicator may be configured according to many preferred embodiments, among which may include a hollow cylinder, a split indicator ring, a co-extruded ring, and a multi-faceted polygonal cylinder.

摘要： 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.
