Abstract
An injection device includes a housing having a longitudinal axis extending. A dose setting member is rotatable in the housing in a first or second direction about the longitudinal axis. A plunger extends through a bore of the dose setting member and into a bore of a barrel engaged with the housing. Pushing on an arm extending through a slot in the housing rotates the dose setting member in the first direction. As it rotates, indicia on the dose setting member are progressively displayed through an aperture in the housing. An actuator is engaged to release the dose setting member to rotate in the second direction and this rotation causes the plunger to move axially within the barrel's bore and push the pre-set dose of fluid therefrom. The dose setting member remains in a constant axial position within the housing during rotation in each of the first and second directions.
