Abstract
A self-use medical injector has a knob at the rear end of a barrel which is rotated from a zeroed position to set the dose and which rotates back again, to the zeroed position, when the injector is fired. A scale is provided on the knob ( ) or barrel ( ) and a datum mark or indicator on the barrel or knob co-operates with the scale. There is a raised stud ( ) providing the indicator or the zero mark of the scale. An annular member ( ) fitted over the knob if the stud is on the barrel or over the barrel if the stud is on the knob, has a projection ( ) which is registered with a mark on the scale corresponding to the required dose. This projection abuts the stud when the knob is rotated and thus sets the knob for the correct does.
