Lol, yes it worked... but 2b honest, he told me about it several years ago b4 I was diabetic and only suffered gestational diabetes so didn't really care too much (sit, look interested and nod!). I know he worked on the plastics... he has since moved on to the new key hole surgery machine (the one which is controlled by surgeons out of the room to reduce risk of infection) then checking the parts surgeons broke putting into people (hip replacement and brackets to fix breaks etc) and now is on the nitric oxide machine developing for blue babies to make smaller and more efficient!
As to the pen... my guess would be something similar to the Sat's meter (to measure blood gasses) but seems like @Tipetoo beat me to providing links.
