The present 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 (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), and a piston rod (30) coupled to the housing (10) and to a drive sleeve (40). Rotation of the drive sleeve (40) relative to the housing (10) causes the piston rod (30) to translate relative to the housing (10). The piston rod (30) is coupled to the housing (10) via a threaded interface (16, 31) with at least two different pitches.
摘要:
A dose setting mechanism for a drug delivery device includes a primary drug delivery assembly and a secondary drug delivery assembly. The dose setting mechanism includes a primary dose dial component for setting a dose in the primary drug delivery assembly and a secondary dose dial component for setting a dose in the secondary drug delivery assembly. The primary dose dial component and the secondary dose dial component are configured to rotate during dose setting. A gear mechanism is configured such that in a first phase of the dose setting, rotation of the primary dose dial component is transferred to the secondary dose dial component and such that in a second phase of the dose setting, the secondary dose dial component is decoupled from the primary dose dial component such that rotation of the primary dose dial component is prevented from being transferred to the secondary dose dial component.

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 housing for such a device. The housing comprises a twin-shot injection moulded casing with at least one window and at least one interface for engaging a further component part of the drug delivery device. The casing comprises a first shell injection-moulded in a translucent material and a second shell injection-moulded in an opaque material. Further, the disclosure is directed to a method for producing such a housing.
