Abstract: A method and system for retaining a drug cartridge in a cartridge holder. As an example, a retaining member for retaining a drug cartridge in a cartridge holder includes at least one connection feature for connecting to the drug cartridge. The at least one connection feature is on an outer wall of the retaining member. The retaining member further includes at least one retention feature, and this at least one retention feature extends from an inner wall of the retaining member. When the retaining member is connected to the cartridge holder, the retaining member retains the drug cartridge in the cartridge holder.

Abstract: A locking mechanism is provided for use with a reservoir and a reservoir holder so as to prevent unwanted tampering with the reservoir. The mechanism comprises a main body that is coupled to the reservoir. A first bendable feature is provided on the main body. The first bendable feature snaps from a first position to a second position. In the second position, at least a portion of the bendable feature retains the reservoir within the locking mechanism.

Abstract: An assembly is disclosed comprising: a reservoir holder, a dose setting mechanism, and flexible fastener configured to fasten the reservoir holder to the dose setting mechanism, wherein the flexible fastener is provided at one of the reservoir holder and the dose setting mechanism. The flexible fastener is configured to releasably fasten the reservoir holder and the dose setting mechanism to each other. Moreover, said flexible fastener is arranged on a retention ring provided at the one of the reservoir holder and the dose setting mechanism. Furthermore, a drug delivery device with such an assembly is disclosed.

Abstract: Disclosed herein are cartridge assemblies that include coding features that help dedicate a medicament reservoir to specific injection devices. An exemplary cartridge assembly comprises a cylindrical inner surface for holding medicament and a cylindrical outer surface comprising at its proximal end one or more stops configured as coding elements protruding from the cylindrical outer surface. Each coding element is configured only to engage a corresponding coding feature on a dose setting and delivery mechanism, thereby allowing only the correct cartridge assembly to connect to the dose setting and delivery mechanism.

Abstract: A ferrule and a cartridge for use with a drug delivery device. A neck portion of the cartridge comprises a first coding feature. The ferrule comprises a main body defining a bore that extends from a proximal end and a distal end of the main body. The bore is configured for receiving the cartridge. A pass through is defined by the distal end. A coding feature is provided along at least a portion of the main body of the ferrule. This coding feature cooperates with a corresponding coding feature provided by a drug delivery device. Further, the ferrule is configured to cooperate with the first coding feature of the neck portion of the cartridge.

Abstract: A system for a drug delivery device comprising a reservoir holder configured to hold a reservoir, and an alignment interface comprising a main body configured to be coupled to the reservoir. A first alignment feature is provided on the main body. The first alignment feature cooperates with a corresponding alignment feature provided by the reservoir holder such that when the reservoir is inserted into the holder, the first alignment feature cooperates with the corresponding alignment feature provided by the holder so as to rotate the alignment interface and thereby align the alignment interface within the holder. Thus, the reservoir may be aligned within the reservoir holder. The first alignment feature may comprise at least one protrusion provided on the main body of the interface. The system further comprises one or more coding features.

Abstract: Disclosed herein are fastening features for cartridge assemblies that include coding features that help dedicate a medicament reservoir to specific injection devices. An exemplary cartridge assembly comprises a cylindrical inner surface for holding medicament and a cylindrical outer surface comprising a fastening feature having a first coding element protruding from the cylindrical outer surface. The coding element is configured to engage a complementary coding feature on the fastener on a dose setting member specifically configured to dispense the medicament, thereby allowing only the correct cartridge assembly to connect to the correct dose setting member.

Abstract: A set of members for a drug delivery device comprises at least two components for the device, wherein both components are provided with a marking, the markings being substantially equivalent or identical. Furthermore, a drug delivery device and a set of drug delivery devices are provided.

Abstract: An identifier for a medicament reservoir is provided, wherein the identifier comprises a malleable sheet of material. The sheet of material comprises a top surface and a bottom surface. The bottom surface may be used to apply the identifier to a surface of the medicament reservoir. A first three-dimensional feature is attached to the sheet of material. The three-dimensional feature may be representative of a medicament contained in the reservoir and may further comprise an alignment feature. In addition, the three-dimensional feature may be coded for a particular drug delivery device. Such drug delivery devices could comprise pen type drug delivery devices.

Abstract: A method and system for detecting information related to a drug reservoir. The method includes transmitting energy at a coded material disposed on a drug reservoir, where the energy has at least one predefined characteristic. The coded material identifies information related to the drug reservoir. The coded material modifies the energy and emits the modified energy to a receiver. The method further includes receiving at the receiver the modified energy. The method further includes determining information related to the drug reservoir based on the modified energy as the drug reservoir is loaded into a drug delivery device.

Abstract: A coded cartridge holder for use with a drug delivery device is provided. The cartridge holder includes a fastener that becomes operative based in part on a length of a cartridge or a diameter of the cartridge. In one embodiment, the cartridge holder is coupled to the drug delivery device. The cartridge holder comprises a first blocking feature. The drug delivery device includes a cartridge detector comprising a second blocking feature. This feature may be a pin, for engagement with the first blocking feature of the cartridge holder when the cartridge acts on the cartridge detector. The cartridge holder may further include a fastening mechanism configured to fasten the cartridge holder to the drug delivery device only when the second blocking feature engages the first blocking feature.

Abstract: A coded collapsible drug reservoir (200) and a drug delivery system (100) including a coded collapsible drug reservoir (200). The drug reservoir (200) includes a collapsible housing (202) and a port (204) in communication with the collapsible housing (202). The drug reservoir (200) further includes a coding feature (206) disposed on the drug reservoir (200), and the coding feature (206) identifies the drug reservoir (200).

Abstract: The present invention relates to a drug delivery device (6) comprising a dose button (1). Furthermore it relates to a method for manufacturing a dose button (1) by using a cutting-off process. The aim of the present invention is to minimize the risk of using a drug delivery device (6) containing a wrong drug. By means of tactile features, a drug delivery device (6) is distinguishable from another drug delivery device (6) containing another type of drug. This tactile feature is manufactured by using a dose button (1) out of metal which is milled or lathed.
