Abstract
A dose delivery mechanism includes a housing, a piston rod that acts on a plunger sealing a fluid compartment and moves in an axial direction relative to the housing to deliver a set dose, and a dose setting member that is movable relative to the housing during dose setting. A position of the dose setting member relative to the housing defines the set dose, and in an as-delivered condition the dose setting member is preset to a position that corresponds to a set dose higher than zero.
Claims20
A dose delivery mechanism comprising:
- a housing;
- a piston rod configured to act on a plunger sealing a fluid compartment and to move in an axial direction relative to the housing to deliver a set dose;
- and
- a dose setting member movable relative to the housing during dose setting;
- a position of the dose setting member relative to the housing defining the set dose, and
- in an as-delivered condition the dose setting member being preset to a position that corresponds to a set dose higher than zero.
A method for providing a dose delivery mechanism having a housing, a piston rod configured to act on a plunger sealing a fluid compartment and to move in an axial direction relative to the housing to deliver a set dose, and a dose setting member that is movable relative to the housing during dose setting, a position of the dose setting member relative to the housing defining the set dose, the method comprising:
- delivering the dose delivery mechanism to a costumer in a state preset to a dose higher than zero.
