    摘要: A dose indicating mechanism for a drug delivery device for displaying of a dose of a medicament to be dispensed by the drug delivery device includes an elongated housing extending in an axial direction and having at least a first window and a second window that are spaced apart from each other in axial direction. The dose indicating mechanism further includes a dose indicating sleeve movably disposed in the housing and having at least one dose indication coinciding with the first window to display the size of a dose actually set, and an indicator operably engaged with the dose indicating sleeve and axially displaceable relative to the housing to coincide with the second window for indicating an operational status of the dose indicating mechanism.

    摘要: A drive mechanism of a drug delivery device for dispensing of a dose of a medicament, includes an elongated housing extending in an axial direction, a piston rod to operably engage with a piston of a cartridge to displace the piston in axial distal direction, a drive sleeve rotatably supported in the housing at least in a dose incrementing direction against the action of a spring element, and a ratchet mechanism to rotatably fix the drive sleeve relative to the housing. A first ratchet body has a first and a second ratchet element to alternately engage with a toothed profile of a second ratchet body. One of the first and second ratchet bodies is operably engaged with the housing and wherein the other one of the first and second ratchet bodies is operably engaged with the drive sleeve.

    摘要: A drive mechanism for a drug delivery device includes an elongated housing extending in an axial direction and a piston rod to operably engage with a piston of a cartridge to displace the piston in an axial distal direction. A drive sleeve is rotatably supported in the housing, operably releasable from the piston rod for setting of a dose, and operably engageable with the piston rod for dispensing of the dose. A dose limiting member is engaged with the drive sleeve and engaged with the piston rod in such a way that it is displaced in axial direction relative to the drive sleeve when the drive sleeve rotates relative to the piston rod during a dose setting procedure. At least one stop is configured to engage with the dose limiting member for limiting the axial displacement of the dose limiting member during the dose setting procedure and to impede further displacement of the drive sleeve relative to the piston rod.
