I am a little late to this discussion, but I would like to thank Kristin for your comments on the Sure-T. I just started pumping in August 2010 and basically had no problems with the Silhouette. However manual insertion was sometimes hard for me when it came to 'hard to reach' places. I tried the Sure-T on the recommendation of a friend here on TuDiabetes and it works beautifully.
I have a question about changing the Sure-T every 2 days. Is that something that is a personal choice or is it accepted practice on the recommendation of Medtronics? Also, is it OK to re-use a reservoir if your supplies are getting low while waiting for your next shipment?
Mayumi, I was told by my diabetes educator that leaving the Sure-T (or any other insertion device) in longer than recommended can cause "tunneling" which is some kind of problem with the skin and it's ability to absorb properly. She said it may not be evident for a while, but the idea is to prevent the problem from starting. I like Kristin's idea of reinsertion. Not sure about reusing the reservoir. I've wondered this, too.
I know some people who reuse reservoirs and have had no problems. I tried it once. But I don't feel confidence about it. Reservoirs have some lubricant that determines how easily is slides and I wonder how quickly that wears off. I guess using it twice shouldn't be a problem.
I experienced the negative effects of leaving infusion sets in too long. I used to leave mine in for 6 days and I have a ton of scar tissue.
Relocating the Sure-T is not something that I think that Medtronic would advise because it is not sterile when you re-insert. But my doctor said just to clean with alcohol and re-insert.
I have had to relocate a sure-t when I put into a sensitive area and then because the adhesive doesn't work as good I put a ReliaMed Transparent Thin Film over it so it will stay in place, works for me.
