Making crafts out of old insulin pump equipment might be something fun to do. Maybe even a way to get kids to feel better about insulin pumps.
The easiest thing to do is to make these things. Just pull the rubber rings off insulin reservoirs and link them like this.
There are large rings and small rings. Mix and match. This one has large ones on the left and small ones on the right.
I'm sure you can use pump tubing to make “scoobies”. I wonder if you could knit with it......
I can think of a few ways to dress up a test strip canister to look like a little dude. Get creative!
