摘要:
A dynamic identification system for a multi-dose injection device includes a dose dial sleeve (40) containing indicia (41; 42) of the medicament contained within the device becomes visible or available to the olfactory or gustation senses only during dose setting as the dial sleeve (40) is translated proximally out of the outer housing of the device. A user can readily identify the medicament contained within the device (1) as the dose is being set. A static identifier (50) located on the device that matches the dynamic identifier on the dial sleeve (40) can also be used as a medicament identifier.

The present invention relates to a drug delivery (5) comprising a housing (10) with a proximal end (30) and a distal end (22), a cartridge holder (14) adapted to retain a cartridge (16), the cartridge holder (14) comprising an at least partially transparent side wall (36), a piston rod (26), the piston rod (26) being adapted to drive a piston so as to engage the piston (28) into the cartridge (16), anda plurality of symbols (32) on the piston rod (26), the symbols (32) representing dosage information during operation of the drug delivery device (5) and being visible through a window aperture (40) in the housing (10) or in the cartridge holder (14). Furthermore, using a plurality of symbols (32) on a piston rod (26) to represent dosage information during operation of the drug delivery device (5) is disclosed.
摘要:
A drive assembly for a medication delivery device comprising a housing, a drive member moveable in the proximal direction for setting a dose of the medication and in the distal direction for delivering the dose, a piston rod driven by the drive member in the distal direction during movement of the drive member in the distal direction for delivering the dos. A restriction member for restricting proximal movement of the piston rod during proximal movement of the drive member by mechanical interaction of the restriction member with a stop feature of the piston rod. The restriction member and the stop feature are arranged for the piston rod to be moved proximally a first distance during a first proximal movement of the drive member before the restriction member and the stop feature interact mechanically.

A resettable dose setting mechanism for a drug delivery device comprising a driver for driving a spindle of the drug delivery device is provided. Said driver comprises a first component and a second component rotationally coupled to said first component. During resetting of said drug delivery device, said first component is rotationally decoupled from said second component.

摘要:
A spindle (242; 414; 542; 642) for driving a bung of a cartridge is provided. The spindle includes a generally circular shaft having an outer surface (560). The generally circular shaft extends from a distal end to a proximal end of said circular shaft. A first helical groove (219; 519; 619) is provided along a first portion of the outer surface. The first helical groove having a first pitch. A second helical groove (221; 521; 621) provided along a second portion of the outer surface of the generally circular shaft. The second helical groove overlapping the first helical groove. The second helical groove having a second pitch.
摘要:
The present invention relates to a dose setting mechanism for a drug delivery device and a method of using same. The mechanism comprises a housing, a mechanism member movable in a first axial direction relative to the housing during dose setting and movable in a second, opposite axial direction relative to the housing during injection, wherein the mechanism member is designed and arranged such that the mechanism member is able to change its condition between a first condition preventing movement in the second axial direction and a second condition allowing movement in the second axial direction, and a switching member forcing the mechanism member to change from its second condition into its first condition at a predefined position of the movement in the first axial direction during dose setting.
摘要:
A drug delivery device with differentiating features is provided. The drug delivery device comprises a dose setting mechanism, a cartridge holder, and a cartridge contained within the cartridge holder. The cartridge holder is secured to the dose setting mechanism and comprises a collar or ring. The ring has the same color as other differentiation features on either the dose setting mechanism or the cartridge, or both. The color-coded ring is configured on the cartridge holder such that when the cartridge holder is assembled with the dose setting mechanism, the color-coded ring remains visible.
摘要:
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.
摘要:
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.
