  • Drug delivery device with dose reset mechanism
    Patent number: 11167092
    Abstract: Drug delivery device adapted to expel a set dose, comprising an expelling mechanism with a drive spring, a dose setting mechanism with first and second dose setting ratchet parts, a bias spring as well as control means. The control means is adapted to rotate the second ratchet part in a first direction to thereby set a dose when rotating the dose setting member in the first direction, and move the ratchet parts axially out of engagement with each other when the dose setting member is rotated in the opposite direction. When the first and second ratchet parts have been axially disengaged, the drive spring will rotate the second ratchet part in the second direction to thereby reduce the set dose, the bias spring moving the ratchet parts axially into engagement with each other again, this resulting in the set dose being reduced corresponding to one tooth of the ratchet mechanism.
