Ok folks. I have the bubble issues again. I can't seem to find a way that works more than once which leaves me with a reservoir free of bubbles. I've tried pretty much everything that I can. I do believe I've got a duff set of reservoirs (lot no. H7613619 for those interested.) Is there anything that anyone can suggest that I do as I am getting close to my wit's end with this because it's getting so damn frustrating. I mean I'm doing everything by the book and other things that aren't in the book. I mean a few weeks ago I ordered five boxes of reservoirs, all the same lot number as mentioned earlier. I'm now down to one as all of those four boxes used were useless. I can remember one that I had free of bubbles and that's it. The bubbles that I get are tiny ones that accumulate around the shoulder of the reservoir and don't shift no matter what I do. It comes to the point that when tapping the reservoir with a pen just makes the situation worse than it was to begin with. So basically... HELP!

Hi Tom,
I sometimes get a lot of small bubble that concentrate at the top of the reservoir. I've also found that tapping or flicking the resvoir makes it worse.
One solution that works well for me in these situations is to leave the reservoir upright in the fridge for a few days. The bubbles tend to join together in one big bubble which is then easy to remove.
I tend to fill my reservoirs in advance (as many as I can get from a single vial of insulin) and leave them in the fridge until I need them. A few hours before a change, I will take a reservoir out of the fridge to let it get up to room temperature, I'll then get rid of any remaning bubbles and change as normal.
When I'm down to my last filled reservoir, I do another batch from my next insulin vial.

No worries - I hope it works for you.
Feel I am bearer of bad news, Red Pumper, sorry... Have now heard and read several times that it's not good to leave insulin in reservoirs for any length of time...something about the insulin degenerating... ? ... anyway, it's supposedly a BAD thing to do.
Saying that, we do find that leaving a filled vial alone even for 15 minutes tends to concentrate whatever bubble is there, so easier to get rid of...
Like Shelb1uk, we de-gas. It starts out feeling like a pain, but the grief it saves is worth it. We have not had a single proper bubble problem since starting this, about six months ago...

Maybe I'll stop doing three at a time but filling one a couple of days in advance shouldn't cause any problems. It's just handier to have one ready when it comes to doing a set change.

Hiya
Ok I'm also not wanting to upset anyone but no-one should prefill reservoirs and leave them for a few days, hours ok but not days. It is all about insulin sticking and not working properly.
Also and this is going to sound awful but it is what I have been told by a very excellent and respected member of the diabetes world that bubbles in reservoir are technique only, nothing else.
Hope that I haven't upset anyone.
Tom, if you really think you have dodgy reservoirs ring Medtronic, they will replace them. I'm happy to come visit and we can fill reservoirs together. I never get bubbles and if there are the odd one, I can get rid of them. I'm not blowing a trumpet here, I just have been doing it a lot longer. Am happy to help if you want me to.

Sam, have they said anything about you doing a carb counting course before you start the pump? I know you know how to do it, but I thought some sort of formal course was a prerequisite

Nope, none at all - I don't have to do one because I'm pretty proficient at it now
The only thing she said I could do if I wanted was look at their online thing, but as I've already done it there's no need. 🙂

It's not my intention to pass on bad advice to anyone on this forum.
I was just stating what worked for me.
It was my DSN that advised on prefilling cartridges when I moved on to my pump in February.
If the professionals can't agree on good practice, then what chance have we?
Keith.
