Hi everyone, I've recently been approved for an insulin pump and it will probably be the medtronic one. I'm just wondering which size I should go for? There are two sizes, a 1.75 ml and a 3 ml. The dimensions are very similar for both, the only difference being the larger one is about 1.5 cm longer. I tend to eat a bit of chocolate in the evening and bolus for that so I take about 50 or so units of novorapid a day and currently my basal is 9 units. The manufacturer advice is to go for the larger pump if you take over 50 units a day. When I told the nurse how much insulin I was having each day she said definitely go for the bigger pump. She then said that I would have to change the resevoir every three days at the same time as changing the cannula. The thing is, I don't know if she was accounting for the fact that my insulin dosage is likely to go down - because I'm on a pump.
If I followed her advice and went for the larger pump could I just fill the resevoir to whatever level I wish (I know they also take the smaller resevoirs) to save throwing away any insulin. It's probable that a 3ml resevoir would last me 6 days or so so should I just change the resevoir when empty? If I went for the smaller pump, it's quite possible that it would last me three days - 60 or so units minus 20-25% (for being on a pump) times 3 equals about 140 units so perhaps I should go for that one?
If I want the smaller pump I'm going to have to call the nurse to ask her to change it (she might not be willing) so I'd really appreciate everyone's advice. Thanks very much.
