I have the One Touch ping pump and meter. I will have to switch to MDI due to insurance. I think if I leave an old empty cartridge in the pump to confuse the pump (but with no infusion set attached) and set the basal rate to zero I could have the BG input, put in my carbs, and have the pump calculate the IOB or BOB and tell me how much to take. I could then adjust it according to the 1/2 unit pen I am going to get. I will be able to download reports for my diabetic educator and diabetic nurse appointments. This is theory, has anyone tried this?
