a body with an attachment mechanism at a proximal end configured to connect a container holding a cartridge containing a quantity of medicament;
a dose setting mechanism comprising:
a dose selector rotatably fixed to the body, where the dose selector comprises one or more dose stops configured to allow only a finite set of predetermined fixed unit doses that can be set using the dose setting mechanism;
a snap element rotatable relative to the dose selector and comprises a fixed set of splines;
a fail-safe component configured to prevent a user of the injection device from setting a dose other than one of the finite set of predetermined fixed unit doses;
a floating spline axially fixed to the snap element, where the snap element can rotate relative to the floating spline during dose setting and dose delivery; and
a dose knob having a first position during dose setting and a second position during dose delivery, where in the first position the dose knob is splined to the fixed set of splines but not splined to the floating spline and when in the second position the dose knob is splined to the floating spline but not the fixed set of splines.
