Abstract: Drug delivery device adapted to receive a drug-filled cartridge comprises a piston drive member for expelling a dose of drug from a loaded cartridge, a motor for driving the piston drive member, a rechargeable electric power source, an electrical connector allowing an external connector of a power source to be connected for recharging the power source, and a controller for controlling operation of the motor. The controller is adapted to detect a condition indicative of an external power source being connected to the electrical connector and subsequently disable the expelling assembly to thereby prevent that drug can be expelled from a loaded cartridge when an external power source has been connected to the electrical connector.

Abstract: A drug delivery device adapted to receive a drug-filled cartridge (10), comprising dose setting means allowing a user to set a desired dose of drug to be expelled, an electronic controller (70,270) adapted to control a motor (51) to move a drive member to thereby expel an amount of drug from a received cartridge corresponding to a set dose, and means for estimating the amount of free air in a loaded cartridge. The controller is adapted to detect an error state if the estimated amount of free air in the cartridge is larger than or equals a given percentage of the amount of drug corresponding to a set dose.

Abstract: A drug delivery system comprising a controller adapted to detect when a given user-actuated operation being part of the expelling of an amount of drug is performed, record detected operations as a function of time, and estimate, based on recorded operations, time parameters for the detected operations, thereby providing time parameters for a medical regimen on which the detected operations are assumed to be based upon.

Abstract: A drug delivery device comprising drug expelling means for expelling an amount of drug, a number of user-oriented structures, and individual visual communication means arranged in the vicinity of at least two user-oriented structures. The device further comprises control means adapted to detect an error condition associated with each of the at least two structures, and actuate the visual communication means associated with a structure for which an error condition has been detected.

Abstract: A drug delivery device comprises drug expelling means and a drug-filled cartridge, the cartridge comprising an outlet and an axially displaceable piston. The drug expelling means comprises a drive member adapted to engage and axially move the piston to thereby expel an amount of drug from the cartridge through the outlet, and a motor for moving the drive member. The device further comprises a display adapted to display a dose amount to be expelled, communication means allowing dose setting data to be received from an external device, and an electronic controller adapted to store received dose setting data, control the display, and control the motor to move the drive member to thereby expel an amount of drug corresponding to a set dose.
