The present invention relates to a drive mechanism of a drug delivery device for setting and dispensing of a dose of a medicament, the drive mechanism comprising: a housing, a piston rod to operably engage with a piston of a cartridge to displace the piston in a distal direction, a rotatable member arranged on an axially extending axis of rotation in the housing, said rotatable member being rotatable in a dose incrementing direction against an action of a spring element and being operably engageable with the piston rod during the dispensing of the dose, and a clutch element comprising at least one radially displaceable clutch element to engage with a rim of the rotatable member with a variably adjustable strength.

A drug delivery system for injecting a medicament includes a container including a closure and a stopper configured to move within the container from a pre-use position to a post-use position. The system includes a drive assembly configured to move the stopper between first and second positions, and a spacer assembly engaged with the stopper configured to be engaged by the drive assembly. The spacer assembly includes a first spacer portion received within the stopper, a second spacer portion spaced from the first spacer portion, an inner plunger, and a spacer shuttle received by the inner plunger. The inner plunger, the spacer shuttle, and the second portion are configured to move relative to the stopper, where movement of the second spacer portion is restricted by the spacer shuttle, movement of the spacer shuttle is restricted by the inner plunger, and movement of the inner plunger is restricted by the stopper.

System comprising a sensor assembly (3, 4, 5, 6) adapted to measure a magnetic field, and a moveable element (1) adapted to be moved relative to the sensor assembly between two positions by a combined axial and rotational movement, the rotational movement having a pre-determined relationship to the axial movement. A magnet (3) is mounted to the moveable element and configured to generate a spatial magnetic field which relative to the sensor assembly varies corresponding to both the axial and rotational movement of the magnet and thus the moveable element. A processor is configured to determine on the basis of measured values for the magnetic field an axial position of the moveable element.

A medicament delivery device is provided. The medicament delivery device may include, among other features, a cartridge holder mounted in a housing and configured to receive a cartridge containing a medicament. The device may also include an outer cap detachably connected to the housing, and a coupling mechanism configured to connect the outer cap to an injection needle holder to which an injection needle is fixed. The coupling mechanism may include a rotatable member configured to be connected to an injection needle holder. The coupling mechanism may also be threadedly engaged with, and rotatable to, the outer cap. The configuration of the device may allow for quicker and more efficient delivery of medicament.

A medicament injection device comprising: a needle holder holding a needle, a pivotable cartridge holder, the pivotable cartridge holder being pivotable from an open state to a closed state, wherein the pivotable cartridge holder is arranged to receive a medicament cartridge in the open state, and wherein the needle holder is axially movable towards the pivotable cartridge holder when the pivotable cartridge holder is in the closed state.

A system for measuring injection of a liquid medicine includes a syringe body having proximal and distal ends, a syringe interior, and a syringe flange at the proximal end thereof. The system also includes a stopper member disposed in the syringe interior. The system further includes a plunger member coupled to the stopper member and configured to be manipulated to insert the stopper member distally in the syringe interior relative to the syringe body. Moreover, the system includes a needle coupled to the syringe body at the distal end thereof. In addition, the system includes a sensor flange removably coupled to a syringe body. The sensor flange includes a sensor to measure an injection characteristic and a processor to analyze the injection characteristic to determine an occurrence of an injection event.

A coded collapsible drug reservoir and a drug delivery system including the coded collapsible drug reservoir. The drug reservoir includes a collapsible housing and a port in communication with the collapsible housing. The drug reservoir further includes a coding feature disposed on the drug reservoir, and the coding feature identifies the drug reservoir.

Methods, systems and devices for detecting an analyte sample, determining an analyte concentration associated with the detected analyte sample, storing the determined analyte concentration and a time associated with the determined analyte concentration, retrieving two or more stored analyte concentrations, and determining an adjusted dose level based at least in part on a current dose level and data associated with the two or more retrieved analyte concentrations are provided. For example, adjustments to dosage levels of long-acting insulin may be provided to assist in the management of diabetes and related conditions.

The present invention relates to a drive mechanism for a drug delivery device for dispensing of a dose of a medicament, and to a respective drug delivery device, wherein the drive mechanism comprises: an elongated housing (30) extending in an axial direction (1, 2), a piston rod (80) to operably engage with a piston (16) of a cartridge (14) to displace the piston (16) in axial distal direction (1), a drive sleeve (60) extending in axial direction (1, 2) and being rotatably supported in the housing (30), a dose setting member (40) rotatably supported on a side wall portion (31) of the housing (30) and being rotatable with respect to an axis (41) extending in radial direction (r), wherein the drive sleeve (60) is operably releasable from the piston rod (80) and rotatably engageable with the dose setting member (40) for setting of the dose.

The invention refers to an injection device comprising a housing (10), containing a cartridge (170) with an amount of liquid to be dispensed, a drive sleeve (41), which is rotationally constrained to the housing (10) during dose setting and spring driven rotatable relative to the housing (10) during dose dispensing, a dose dial member (60) for setting a dose to be dispensed, which is rotatable relative to the housing (10) during dose setting and during dose dispensing, and which is rotationally coupled to the drive sleeve (41) during dose dispensing. The device further comprises a last dose protection mechanism (41, 50, 60) for preventing the setting of a dose, which exceeds the amount of liquid left in the cartridge (170), with a limiter (50), which is interposed between the drive sleeve (41) and the dose dial member (60). Further, the device comprises two different display members (110, 120), each indicating the set dose.
