  • Patent number: 10668223
    Abstract: 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.

  • Patent number: 10420893
    Abstract: A drug delivery device for dispensing of a dose of a medicament includes an elongated body extending in an axial direction, a cartridge holder to accommodate a cartridge at least partially filled with the medicament and having an axially displaceable piston, and a piston rod to operably engage with the piston of the cartridge to displace the piston in axial distal direction. The drug delivery device further includes a coupling member connected with the cartridge holder and being axially displaceably arranged in the body for retracting the cartridge holder into the body during setting of a dose.

  • Patent number: 10420896
    Abstract: 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.

  • Patent number: 10046117
    Abstract: Drive mechanism for a drug delivery device is disclosed. The drive mechanism includes an elongated housing extending in an axial direction. It includes a piston rod that operably engages with a piston of a cartridge to displace the piston in an axial distal direction. It includes a first dose indicating member that is rotatably supported on a longitudinal axis. It includes a second dose indicating member axially adjacent to the first dose indicating member and rotatably supported on the longitudinal axis. It includes a dose setting sleeve extending in an axial direction, rotatably engaged with the first dose indicating member and axially extending through the first dose indicating member to rotatably engage with the second dose indicating member.
