Abstract: A drug delivery device and related method of operation of a drug delivery device is described that includes a housing, a reservoir removably disposed within the housing and having a sidewall defining an interior for containing a drug, a temperature sensor that is configured to measure a current temperature relating to at least one of the reservoir, the sidewall of the reservoir, the housing, or the drug, and an output device that is configured to output data relating to the current temperature.

Abstract: Medication delivery devices, sensing systems, and methods are disclosed for determining the relative axial and rotational movements of its members to determine the amount of a dose set and/or delivered by the medication delivery device. A sensing system comprises a barrel sensor system (100), a drive sleeve sensor system (130), and/or an axial sensor system (140). The barrel sensor system (100) is for detecting the absolute relative angular position of the barrel relative to the housing during dose setting. The drive sleeve sensor system (130) is for detecting the absolute relative angular position of the drive sleeve relative to the housing during dose delivery. The axial sensor system (140) is for detecting the relative axial positions of the dose dial relative to the housing during dose setting and delivery. A controller receives outputs from the sensor systems corresponding to the absolute relative positions to determine the actual amounts of dose set and delivered.

Abstract: A cap assembly for a drug delivery device is described that includes a cap housing defining an internal cavity and a remover configured to be insertably mounted within the internal cavity of the cap housing and having a sidewall with a generally annular configuration. A plurality of retention portions of the remover extend radially inwardly from the sidewall within the internal cavity, such that the plurality of retention portions are configured to grip a needle shield inserted through the remover within the internal cavity of the cap housing. A drug delivery device is also described that includes a cap assembly kit including a cap housing having an internal cavity sized to interchangeably receive one of a first remover or a second remover, where the first remover is configured to receive a first type of needle shield and the second remover is configured to receive a second type of needle shield.

Abstract: Drug delivery devices are configured to inject a drug over an injection time within an acceptable range calculated based on information pertaining to the drug to be injected. In particular, drug delivery devices are described that allow identification of the drug to be injected, calculation or determination of an acceptable range of injection times for the identified drug, determination of a tailored injection time within the acceptable range of injection times, and setting of a delivery speed of a drive such that the drug is expelled over the tailored injection time.

Abstract: An autoinjector drug delivery device configured with a stall and endpoint detection algorithm is described that allows for variations in the fill of the drug, barrel, plunger, and other components. The stall or end point detection can cause the autoinjector to stop an extrusion process.
