Here's what I've been doing for a couple years, and although I'm sure it's not exactly the perfect, doctor approved, way to do it, but it's been working! All A1C's between 6 and 7 :)
- I fill up my reservoir 100% full with insulin, or about 300 Units (Paradigm 722).
- On every third day, I change my infusion set only. I only change the injection site. I do not change tubing or the insulin reservoir.
- When my insulin reservoir gets down to 10 units, I fill it up again, and at this time change both my reservoir and tubing.
My doctor suggest changing both my reservoir, tubing, and infusion set every 2-3 days, but I can't think of a good reason as to why the insulin reservoir should be changed ever 2-3 days. To me, it just seems like a waste of insulin. Comments welcome!
