I'm coming to the conclusion thatt insulin pens should be redesigned . Something thusly :
You take the cap off, screw on a needle, dial up the dose which activates a klaxon:
"OOOORRROOOGAH ! OOOOORRROOOGAH ! Then an automated voice asks " Do you really want to inject N units of insulin now ? Shake once to accept ! "
* shakes pen *
" Do you REALLY want to inject N units of insulin now? Shake once to acknowledge !"
* Shakes the pen with unecessary force and mutters darkly....Dinner is cooling and I'm starving *
" Depress plunger, and PROCEED !"
* Inserts needle in to arm, depresses plunger and ..... the &@£?!! cartridge runs out half way .. You think it's half way...the dial has stuck at a point that could be 5, or 5.5 , it's hard to tell through the tears of frustration and rage.
*
Ah, just a thought!
