摘要:
a main body having a proximal end, a distal end, and a bore that receives the cartridge, the main body further comprising a first segment and a second segment; and a retention feature on the main body suitable for snapping under the bead of the cartridge for securing the cap to the cartridge.
摘要:
The present disclosure is generally directed to a trigger mechanism for initiating dispensing doses of a medicament from a drug delivery device. The trigger mechanism includes a trigger element movable in a first direction relative to a counter element. To provide a feedback to a user of the trigger mechanism, the trigger element includes a first interference member and the counter element includes a second interference member located with respect to the first interference member such that upon movement of the trigger element relative to the counter element the first interference member contacts and passes over the second interference member, thereby generating an audible and/or tactile feedback. Further, the disclosure includes a drug delivery device for selecting and dispensing a number of user variable doses of a medicament comprising such a trigger mechanism.
摘要:
The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament and to a non-numerical display for such a device. The display comprises a housing with at least one window, a dosing element movable relative to the housing during dose setting and/or dose dispensing, and a movable indicator element visible through the at least one window The indicator element is coupled to the dosing element and/or to the housing such that it moves not proportional to the dosing element.
摘要:
A coding system for a drug reservoir, where the drug reservoir is intended for use with a reservoir holder of a drug delivery device. The coding system includes a collar fitted around the drug reservoir. The collar includes a coding feature that is configured to pass through a corresponding coding feature provided by the reservoir holder of the drug delivery device.
摘要:
A connector (50, 150, 180, 200, 300, 350, 400) for use with a reservoir (20, 100, 220, 320, 368, 420, 700). The connector comprises a main body (52, 152, 182, 202, 252, 302) defining a bore (54, 184, 254, 304) extending from a proximal end (58, 186, 258) to a distal end (56, 188, 256) of the main body. The bore is configured for receiving the reservoir. An inner wall (154) extends from the proximal end to the distal end. At least a portion of the inner wall is configured for attachment to an outer surface (22, 222, 422) of the reservoir. An outer wall (156) extends from the proximal end and the distal end. The outer wall is configured for attachment to a drug delivery device. In one arrangement, the outer wall is configured for attachment to a cartridge holder (100) of the drug delivery device.
摘要:
A locking mechanism (200, 400, 500, 600, 700, 800) is provided for use with a reservoir (120, 320, 330) and a reservoir holder (104, 820) so as to prevent unwanted tampering with the reservoir (120, 320, 330). The mechanism (200, 400, 500, 600, 700, 800) comprises a main body (202) with an aperture (204, 430, 530) that is coupled to the reservoir (120, 320, 330). A hinged flange (214, 414, 514, 522, 622, 722) is provided on the main body (202). The flange (214, 414, 514, 522, 622, 722) folds inwards at the pivot point provided by the hinge (215), toward the aperture (204, 430, 530) of the main body (202), allowing the mechanism (200, 400, 500, 600, 700, 800) to pass over the ferrule (324) of the reservoir (120, 320, 330). Once the mechanism (200, 400, 500, 600, 700, 800) is placed over the cartridge (120, 320, 330), the flange (214, 414, 514, 522, 622, 722) folds toward the reservoir (120, 320, 330) at the pivot point, flexing away from the main body (202). The flange (214, 414, 514, 522, 622, 722) rests against the underside (325) of the reservoir ferrule (324), thereby retaining the reservoir (120, 320, 330) within the locking mechanism (200, 400, 500, 600, 700, 800). The locking mechanism (200, 400, 500, 600, 700, 800) may be for use with either a disposable or a reusable delivery device (100).
摘要:
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).
