The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

The disclosed embodiments are directed to secondary methods of communicating with a drug delivery device when the primary method is unavailable. Secondary methods include the use of a pattern of taps on the housing of the drug delivery device to convey authentication information and commands to the drug delivery device. Feedback confirming the interpretation of the pattern of taps may be provided to the user via a vibration, sound, or blinking lights.

Disclosed herein is a reservoir for use in a wearable drug delivery device having multiple chambers of potentially varying lengths or arrangement so as to efficiently utilize available space within a housing of the drug delivery device. Each of the chambers is connected to a fluid path and a liquid drug is drawn from each of the chambers by suction applied to the fluid path. Each of the chambers is fitted with a free piston which is moved within the chamber by the suction applied to the fluid path as it draws the liquid drug out of the chamber, thereby eliminating the need for a mechanical arrangement for moving the piston within each of the chambers.

Techniques related to temporary setpoint values are disclosed. The techniques may involve causing operation of a fluid delivery device in a closed-loop mode for automatically delivering fluid based on a difference between a first setpoint value and an analyte concentration value during operation of the fluid delivery device in the closed-loop mode. Additionally, the techniques may involve obtaining a second setpoint value. The second setpoint value may be a temporary setpoint value to be used for a period of time to regulate fluid delivery, and the second setpoint value may be greater than the first setpoint value. The techniques may further involve causing operation of the fluid delivery device for automatically reducing fluid delivery for the period of time based on the second setpoint value.
