Abstract
The disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing having a proximal end and an opposite distal end, a dose setting member rotatable relative to the housing during dose setting and during dose dispensing, and an axially compressible torsion spring which is rotationally and axially constrained with a first end to the housing. The device further comprises a spring collar, which is rotationally constrained to the dose setting member and axially displaceable thereto between a proximal dose setting position and a distal dose dispensing position. The torsion spring is rotationally constrained with a second, opposite end to the dose setting member via the spring collar, and the torsion spring biases the spring collar into its dose setting position.
