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 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).La presente invención está dirigida generalmente a un dispositivo de administración de fármacos para la selección y la dispensación de varias dosis, variables por un usuario, de un medicamento, que comprende una disposición de chasqueador. El dispositivo comprende un alojamiento (10), un selector de dosis (80) que puede funcionar para establecer una dosis por la rotación relativa al alojamiento (10), un manguito de números (60) acoplado al selector de dosis (80) y dispuesto dentro del alojamiento (10) de tal manera que por lo menos una parte del manguito de números (60) sea visible a través de una primera abertura (11b) en el alojamiento (10), un vástago (30) de pistón acoplado al alojamiento (10) y a un manguito impulsor (40) de tal manera que la rotación del mang
