20130090602 | CODED FASTENER ASSEMBLY - 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. | 04-11-2013 |
20130096509 | CARTRIDGE HOLDER AND ALIGNMENT INTERFACE - 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. | 04-18-2013 |
20130204201 | CODED DRUG RESERVOIR CONNECTION ELEMENT WITH BENDABLE LOCKING ELEMENTS - 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. | 08-08-2013 |

20130218079 | DOSE SETTING MECHANISM AND DRUG DELIVERY DEVICE - A dose setting mechanism that prevents dispensing of a drug when an incorrect cartridge assembly is attached to the dose setting mechanism. Dispense of a drug may be allowed by preventing rotation of a spindle nut of a drug delivery device, and dispense of a drug may be prevented by not preventing rotation of the spindle nut. Preventing dispense of a drug may be accomplished by preventing rotation of the spindle when an incorrect cartridge assembly is inserted. Preventing dispense of a drug may be accomplished by preventing the spindle from applying an axial force on the cartridge when an incorrect cartridge assembly is inserted. | 08-22-2013 |
20130253432 | CODED DRUG RESERVOIR CONNECTION ELEMENT WITH HINGED FLANGE - 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 with an aperture that is coupled to the reservoir. A hinged flange is provided on the main body. The flange folds inwards at the pivot point provided by the hinge, toward the aperture of the main body, allowing the mechanism to pass over the ferrule of the reservoir. Once the mechanism is placed over the cartridge, the flange folds toward the reservoir at the pivot point, flexing away from the main body. The flange rests against the underside of the reservoir ferrule, thereby retaining the reservoir within the locking mechanism. The locking mechanism may be for use with either a disposable or a reusable delivery device. | 09-26-2013 |
20130281962 | TAMPER-EVIDENT INDICATOR FOR A DRUG RESERVOIR - A drug reservoir comprises of a housing having a proximal end and a distal end, wherein the housing is configured to hold a medicament; and a removable feature disposed on at least one of the proximal end and the distal end, wherein the removable feature covers at least in part one of the proximal end and the distal end. | 10-24-2013 |
20140081215 | Eject Button for a Medicament Delivery Device - A medicament delivery device comprises a housing having a longitudinal axis, a medicament delivery mechanism within the housing, a dispense interface disengagement actuator and a detachable dispense interface. The interface is moveable between a first operative position in which the dispense interface is securely engaged and at least partially contained within the housing, and a second non-operative position in which the dispense interface is partially engaged and at least partially extending from the housing such that it can be detached from the housing manually. The travel of the dispense interface from the first position to the second position is along the longitudinal axis in a direction away from the housing and the movement from the first to the second position is actuated by the dispense interface disengagement actuator. | 03-20-2014 |
20140107585 | Medicament Delivery Device with Cap - The invention resides in a hand-held medicament delivery device which comprises a housing containing a first electrical circuit and a battery, a medicament delivery mechanism, and a protective cap releasably securable to the housing. The housing also includes a contactless switch and the cap a switch actuator. The switch is operable between an on state in which the first electrical circuit is connected to the battery and an off state in which the first electrical circuit is disconnected from the battery. | 04-17-2014 |
20140188075 | MEDICAMENT DELIVERY DEVICE WITH CARTRIDGE SENSOR AND CARTRIDGE HOLDER DOOR SENSOR AND METHOD OF CONTROLLING THE DEVICE - A medicament delivery device is presented for the administration of one or more drug agents, wherein the device comprises a retainer for holding a medicament cartridge. The retainer is moveable between an open and closed position. A position sensor for generating a position output is indicative of whether the retainer is in the open or closed position. Further, a cartridge sensor generates a cartridge output indicative of whether the retainer is holding a medicament cartridge. A controller controls a predetermined operation of the device in dependence on the output of the position sensor and on the output of the cartridge sensor. | 07-03-2014 |
