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).

The disclosure 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 having a proximal end and an opposite distal end, a dose setting member rotatable relative to the housing during dose setting and during dose dispensing, and an axially compressible torsion spring which is rotationally and axially constrained with a first end to the housing. The device further comprises a spring collar, which is rotationally constrained to the dose setting member and axially displaceable thereto between a proximal dose setting position and a distal dose dispensing position. The torsion spring is rotationally constrained with a second, opposite end to the dose setting member via the spring collar, and the torsion spring biases the spring collar into its dose setting position.

The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament comprising a clicker arrangement. 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) coupled to the dose selector (80) and 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), a clutch (120) arranged between the number sleeve (60) and the drive sleeve (40), and a dispense clicker comprising a flexible arm (123) and a toothed profile (75). The device further comprises a button (70) operable to effect dose dispensing. The clutch comprises a separate clutch element (120) which is permanently rotationally constrained to the number sleeve (60). The flexible arm (123) is provided on the clutch element (120) and the toothed profile (75) is provided on the button (70).

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:
The present invention is generally directed to a clicker arrangement for use in a drug delivery device and a drug delivery device comprising such a clicker arrangement. The arrangement comprises a first, rotatable element (60) and a second, non-rotatable element (110). One of the first element (60) and the second element (110) comprises a clicker arm (67) and the other of the first element (60) and the second element (110) comprises a cam (117). Upon relative rotation of the first element (60) and the second element (110) the clicker arm (67) is elastically deflectable by the cam (117) and relaxable upon disengagement with the cam (117) thereby generating an audible and/or tactile feedback signal. The arrangement further comprises a third, axially movable element (40) having a ramp (47) for interaction with the clicker arm (67), wherein, when the third element (40) is in a first axial position, the ramp (47) does not interact with the clicker arm (67), which in turn prevents the clicker arm (67) from contacting the cam (117), and when the third element (40) is in a second axial position, the ramp (47) deflects the clicker arm (67) such that the clicker arm (67) contacts the cam (117).
摘要:
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.
摘要:
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.
