Systems and methods are provided for adjusting long acting insulin medicament dosages for a subject. A plurality of timestamped glucose measurements of the subject and insulin injection data is obtained. A first glycaemic risk measures is determined, where the first risk glycaemic risk measure is i) glucose level variability across the glucose measurements, (ii) a variability in fasting glucose levels calculated from the glucose measurements, (iii) a minimum observed glucose measurement in the plurality of glucose measurements (iv) rate of change in ISF, or (v) adherence values. A fasting blood glucose target function is computed based upon at least the first glycaemic risk measure thereby obtaining an updated target fasting blood glucose level that is between a minimum and maximum target fasting blood glucose level. The long acting insulin medicament dosage is adjusted based upon the updated target fasting blood glucose level.

An injection device comprising a housing (12) and a dose selector (16) to set a dose of medicament to be ejected from the injection device. A spring (20) coupled to the dose selector stores energy necessary for ejecting the dose from the injection device. A ratchet (25) arrangement is provided to rotationally couple a ratchet component and an internal surface of the housing in a coupled state and to allow relative rotation between the ratchet component and the internal surface of the housing in an uncoupled state. An over-torque feature (27) located between the dose selector and the spring is actuatable, when the rotation of the dose selector causes the charging force to exceed a defined limit, to reduce the charging force transferred from the dose selector to the spring. Both the ratchet component and the over-torque feature are provided on a single component (28).

The present invention provides a drug delivery device with a dose counting mechanism and an end-of-content identification.

An apparatus includes a housing, an actuator, a lock mechanism, and a medicament container. The lock mechanism selectively engages a portion of the housing such that (1) the lock mechanism is maintained in a substantially fixed position when the housing is in a first orientation and (2) the lock mechanism is removable from the housing when the housing is in a second orientation. The medicament container is moved in a proximal direction when the lock mechanism is removed from the housing to mix a first medicament portion contained within the medicament container with a second medicament portion contained within the medicament container. The actuator can be moved from a first position to a second position when the lock mechanism is removed from the housing to release energy stored within an energy storage member such that the medicament container is moved in a distal direction.

A cap for intake and delivery of a fluid from a syringe is described. The cap includes an outer cap assembly comprising a fluid inlet path and a fluid outlet path and an inner cap assembly configured for innertion into a fluid nozzle of the syringe and to provide selective fluid communication between an interior of a syringe and the fluid inlet path or the fluid outlet path. The outer cap assembly is slidable relative to the inner cap assembly between a first filling position, where the interior of the syringe is in fluid communication with the fluid inlet path, and a second delivery position, where the interior of the syringe is in fluid communication with the fluid outlet path. The outer cap may further slide, relative to the inner cap assembly, to a third closed position where the interior of the syringe is fluidly isolated from the fluid inlet path and the fluid outlet path. Syringes including the cap are also described.

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.
