An amazing little machine that I could not live without. What does it do you wonder? It pumps insulin, hence the name INSULIN PUMP. It for when you have type one diabetes, and the only downers are changing your set (where the insulin actually goes in) and having to bring it with you everywhere. And they cost $4000.
I would probably be dead by now without my insulin pump, I suck at taking care of my diabetes, mostly because its a pain in the ass.
