摘要： An arrangement comprising an optical element and an indication member for a drug delivery device is provided. The indication member comprises a plurality of indicia. The optical element comprises an imaging section and a light-transmissive non-imaging section, wherein the indication member is movable with respect to the optical element such that the indicia can be successively moved into a display position relative to the optical element. The imaging section is configured such that, when a first indicium is arranged in the display position, the first indicium is imaged by the imaging section into an imaging solid angle. The non-imaging section is configured such that light defining a second indicium is deflected by the non-imaging section such that the second indicium cannot be identified by a user in the imaging solid angle on a viewing side of the optical element.

摘要： The present invention is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing (10), a dose selector (80) operable to set a dose by rotation relative to the housing (10), a number sleeve (60) arranged within the housing (10) such that at least a portion of the number sleeve (60) is visible through a first aperture (11b) in the housing (10), a piston rod (30) coupled to the housing (10) and to a drive sleeve (40) such that rotation of the drive sleeve (40) relative to the housing (10) causes the piston rod (30) to translate relative to the housing (10) and a clutch mechanism arranged between the number sleeve (60) and the drive sleeve (40). The clutch mechanism comprises a first interface (42, 62) for rotationally constraining the drive sleeve (40) and the number sleeve (60) depending on the axial position of the drive sleeve (40) and a second interface (43, 121) for rotationally constraining the drive sleeve (40) and the number sleeve (60) via a clutch element (120) depending on the axial position of the drive sleeve (40) and/or the bias of a clutch spring (130).

摘要： A medication injector apparatus such as an injection pen. The injection pen includes a resettable, cartridge plunger drive assembly including an axially floating nut, a cartridge plunger engaging screw, and a drive clutch movable with the nut and which when rotated causes the screw to screw through the nut. When a cartridge assembly is mounted to the pen base, the floating nut and drive clutch are shifted proximally such that the drive clutch is in torque transmitting engagement with a rotatable drive member of the pen, such that rotation of that drive member results in drive screw advancement through the nut in the distal direction. When the cartridge assembly is not mounted to the pen base, the floating nut and drive clutch are biased distally to disengage the drive clutch from torque transmitting engagement with the rotatable drive member and to thereby allow the drive screw to be reset proximally through the nut to a position more retracted within the pen base. The injection pen also may include an injection clicker assembly having a collar arranged coaxially on a drive sleeve and which oscillates axially on the drive sleeve that rotates during medication dispensing to provide an audible clicking sound that indicates injecting use of the pen. The injection pen also may include a doseable quantity identifier that uses a rotational matrix and a sensor for electrically sensing the arrangement of the dose setting mechanism of the pen, which identifier may be part of a therapeutic dose indicating system that utilizes a cartridge recognizer to recognize a concentration of medication so as to allow an automatic determination of a therapeutic dose. The injection pen further may include an assembly for selectively rotating a drive sleeve of the pen, which assembly has a dial that rotates out during dose setting and which translates in without rotation during dose injecting.
