Okay the teacher is not a Rocket Scientist. But, it's not the horror they are making it out to be. The insulin pump is connected to a tiny needle that just goes below the skin into the fatty tissue just below. Takes all of 30 seconds to clean the skin and insert another little needle. You would think the kid had a kidney removed.
However, he may not have been allowed to bring additional needles with him... most pumps require new needles for each new insertion.
it is not SOP to re-insert a used needle into the body for pumps (not to mention IVs, shots, etc)!
Also - his insulin could have leaked out if the pump was not turned off when the needle was removed!
Well, it's no cakewalk either! My son wore a pump for two years, and one of his greatest worries was the needle being ripped out ... either by someone grabbing it, mistaking it for a phone, or the pump just falling out of his pocket. Maybe you've had to deal with this issue on a daily basis, I don't know. If you're speaking from experience, you're a real he-man for dealing with it so well. If not, your sense of compassion is sorely lacking.
