Wow just hearing words like "glucometer" and "test tape" make me cringe.
I still hear nurses use the term glucometer to mean any kind of meter.
I had the paramedics called a few years ago when I had a low event, and they carried both oral glucose gel and a GIANT DEXTROSE syringe for IV injection.
I live in the US but I guess every state is different. Orange juice and sugar seems silly as orange juice alone is usually pretty potent.
I was dx,d in the late 80s and they showed me how to clean a glass syringe because it was part of their checklist. Of course no one had used glass syringes for 30 years prior.I believe it had a 12 gague needle too.
Someone had described an injector device similar to the lancet device that was posted here for that giant needle in that glass syringe.
Ill bet that was loads of fun.
