Hi all! What do you all think about reusing tubing?

You aren't 'supposed to'.. but is this like how you are supposed to change lancets every blood test? ;)

I ask because (in Canada at least) the Medtronic Silhouette insertion sets come in boxes with tubing or without tubing. They used to come in boxes where 5 had tubing and 5 didn't.. but now they don't and it's kind of annoying. But is tubing really a thing where I could be fine if I just changed it when something was 'up' with it?

A medtronic rep kinda implied that a lot of people are using them more than twice, and I never thought about doing this, but I can't see any major problems as long as checking regularly for kinks etc.

If reusing is fine is there a limit to how long one set of tubing should go for?

I reuse the tubing, but I make sure when I prime that the tubing is free of air bubbles.

I reuse everything. Tubing, cartridges, even sets (Animas contact-D has steel cannula and can be moved, re-taped). But I don't push it as far as some. Cartridges, twice; sets for the life of one cartridge fill = 1 week, tubing change when set changes... But I'd guess everything might go a lot longer.

Do you leave the same set in for a whole week? I can't do that.. My sites are always starting to get red and irritated after 3-4 days.

No, I don't leave it in the same spot. Mine get sore too. So at 3 days I pull out the needle, trim away the adhesive circle, clean the needle w/ an alcohol swab, then use athletic tape to tape it down in a new spot. So the set lasts a week, but not in one spot. Most of my 44 yrs of D-life I couldn't afford insurance so I became uber-thrifty:-)

I don't reuse tubing but I only change the tubing when I change the reservoir which is every 4 or 5 days.

Apparently re-using tubing and the reservoir can change the insulin consistency into almost a jelly instead of a liquid, thereby causing it not to work. I had a girl tell me that it happened to her often, but I've never had this experience.

I often re-use my reservoir and tubing. You can now buy a box of 10 Silhouette Cannula's - no tubing at all. So I will buy 1 box of Cannula's ONLY and 1 box of Cannula/Tubing and change the tubing every other time. I re-use my reservoir about 10 times before changing, and have gone 4 or 5 site changes without changing the tubing (if I run out or something). I think as long as you keep an eye on things, you should be fine.

Yeah I alternate tubing and non-tubing.. the boxes used to be 5 of each rather than separate. I was told they changed it because people were reusing the tubing for longer so there was a demand for boxes with no tubing at all.

I too change the tubing every 4 days when I change the reservoir. As long as you prime to make sure insulin is getting through it should be OK.

That's what I do right now.. well.. every other site change, I change the tubing. But I think many people do it much more infrequently.

Back in the day of my Disetronic pump, tubing was to be used more than once. The cartridge held a lot of insulin, so I just attached the current tubing to the new set, primed and put in the new set. It was standard and the way I was taught to do it by their pump coach.

Note that medtronics sets include tubing and cannula. So there is no monetary savings to reuse of tubing except for unused insulin left in the tubing. In another forum, it was posted that tubing, depending on length, holds between 5 and 8 units of insulin when full. So with set changes every two or three days, it amounts to a lot of wasted insulin.

I have not reused any of this, but I can't stand to lose so much insulin each time I change the quick-set. But I am a newbie with the pump. I didn't even know you could reuse any of this. I wait until the reservoir is almost empty, before I change it. At first I changed it as soon as the pump vibrated and I wasted a lot. You all have given me a lot to think about. Thanks
