A method and system for providing a drug delivery device. The drug delivery device comprises a dose setting mechanism comprising a spindle and a cartridge holder coupled to the dose setting mechanism. The cartridge holder comprising a cartridge having a movable bung at one end of the cartridge. The cartridge holder must be rotated before a dose may set with the dose setting mechanism.

A clutch assembly with a blocking system for a medical injection device, in which a first ratchet sleeve (3) is mounted on the clutch sleeve (2), the first ratchet sleeve (3) being rotatable in two directions and cooperating with a second ratchet sleeve (4) which is mounted on the first ratchet sleeve (3), the second ratchet sleeve (4) being rotatable only in one direction, the housing (1) has an internal toothed ring (1.1), the first ratchet sleeve (3) has at least one ratchet (3.1), and the second ratchet sleeve (4) has an internal toothed ring (4.1) and at least one ratchet (4.2). The second ratchet sleeve (4) and the housing (1) have blocking means (4.3, 1.2) for preventing the arming of the device when an insufficient volume of the medicament remains in the container, by blocking the rotation of the second ratchet sleeve (4) in relation to the housing (1).

An add-on device adapted to be releasably mounted on a drug delivery device, the add-on device comprising an outer assembly with an add-on dose setting member adapted to be coupled to the outer housing of a pen housing, as well as an inner assembly engaging the pen dose setting member and being in rotational engagement with the add-on dose setting member during dose setting. The invention addresses the issue of preventing transfer of movement from the add-on dose setting member to the inner assembly during dose expelling, which in accordance with the invention is realized by rotationally de-coupling the inner and outer assembly during dose expelling.

A syringe is disclosed. The syringe comprises a plunger and a barrel. The plunger can be rotated relative to the barrel to lock, unlock and/or translate the components relative to each other.

The present disclosure relates to a dose detection system for use in combination with a medication delivery device. In one aspect, the system includes a module keyed to the device and including a sensor operable to detect the relative angular position of a sensed element attached to the medication delivery device. The system determines the type of medication contained by the device, and/or the type of device, based on the detected angular position of the sensed element. In another aspect, the dose detection system is used in combination with a medication delivery device including a dose setting member which rotates relative to an actuator during dose delivery. The dose detection system includes a sensor and is operable to detect the relative angular positions of a sensed element attached to the dose setting member during dose delivery and to determine the amount of dose delivered. Related methods are also disclosed.

An injection device for setting and injecting of a dose of a medicament includes: an acoustic feedback arrangement comprising: a first feedback element having a first engaging section and having a free end section located at a predetermined distance from the first engaging section, a second feedback element having a second engaging section configured to engage with the first engaging section, wherein the first feedback element is movable, pivotable or resiliently deformable along a first direction (d1) relative to the second feedback element from an initial state (i) towards a biased state (b), and a sound generator formed by the first engaging section or audibly engageable with the free end section of the first feedback element.

A method of providing and/or injecting octreotide acetate to a subject in need thereof includes storing the octreotide acetate in a cartridge of a multi-use multi-dose injector provided with a variable dose setter and actuator. The injector includes a needle configured for subcutaneous administration of the octreotide acetate, the octreotide acetate having a concentration of 2,500 μg/mL. The method further includes permitting setting of a dose of the octreotide acetate by rotation of the variable dose setter. The injector is configured to provide at least one audible feedback during the rotation. The method further includes operating the actuator to deliver the octreotide acetate from the cartridge through the needle to treat the subject. The injector is provided with multiple surface portions.

A set of at least two drug delivery devices includes a first drug delivery device and a second drug delivery device, The first and second drug delivery devices each include a first set of mutual members that are identical, and the first drug delivery device and the second drug delivery device each include a second set of distinguishing members that differ. The first drug delivery device includes a first connection device for attaching a first dispensing unit to the first drug delivery device and the second drug delivery device includes second connection device for attaching a second dispensing unit to the second drug delivery device, the first and second connection devices differ from each other so that the second dispensing unit is not attachable to the first connection device and the first dispensing unit is not attachable to the second connection device.

A plunger sub-assembly (40, 60, 70; 80) for a pre-filled medicament injector for expelling a dose of a medicament, comprising: a) a container (60) holding a medicament, the container (60) comprising a body (61) with a proximally facing rim surface (64), and a distally slideable piston (63); b) a plunger (40); and c) a tolerance compensating element (70; 80) configured to cooperate with the plunger (40) and to cooperate with either the proximally facing rim surface (64) or the piston (63), the tolerance compensating element (70; 80) being rotatable relative to the plunger (40) to adjust the piston (63) end of dose position. The plunger sub-assembly (40, 60, 70; 80) is formed so that end of dose state occurs by the plunger (40) cooperating with the proximally facing rim surface (64). Pre-filled medicament injectors and methods of assembling a pre-filled medicament injector are further described.

The present invention relates to a drug delivery device for setting and dispensing of a dose of a medicament is presented comprising a housing to accommodate a cartridge filled with the medicament, an electrically operated drive mechanism to be operably engaged with the cartridge to expel a predefined dose of the medicament from the cartridge, and at least one dose element displaceably arranged relative to the housing to set and/or to dispense the dose of the medicament, wherein the dose element and the drive mechanism are mechanically decoupled from each other.
