Oh, Mio My – o


Anyone else out there sick of the Minimed Quickset infusion set? I know I am: about 75% of the time, I develop weird doughnut-shaped bubbles underneath the adhesive (conveniently concealed by the plastic) that collect insulin and interstitial fluid and prevent me from absorbing my insulin doses. This has been a problem for quite some time — and every endocrinologist I’ve gone to has proclaimed the Quickset to be their least favorite infusion set. (Two have told me that the first thing they do when they have a pumper trying to get pregnant is to get them off the Quickset — hardly an endorsement of the product!) Anyway, the conversation usually proceeds as follows:


Doctor: I want  you to get off the Quickset.

Me: Me, too.

Doctor: Why don’t you try the Silhouette instead?

Me: Because I wore the Silhouette for five years and the sites kept getting infected. I had so many problems that I switched to the Quickset.

Doctor: Huh.


Occasionally they suggest I try one of the sets that have a steel needle instead of a plastic cannula (the Sure-T), but I’ll be honest: I’ve never been into that option. Having a needle stay in me all the time doesn’t sound comfortable. Since Minimed’s reservoirs only work with their infusion sets, that means I’ve been stuck.


That is, until now. I recently went to a different doctor and found out that there is a new option from Minimed: the Mio. The Mio is exactly the same as the Animas Inset (as in, manufactured by the same company and everything), but has been redesigned to be compatible with Minimed’s reservoir.


I’ve only tried the Mio a few times, but the way I’d describe it is as follows: it has a vertical cannula, like the Quickset, but clips on in a way that’s more similar to the Silhouette. The benefits of this, as I see it, are two-fold. First, it’s very obvious when it’s clipped in — unlike the Quickset, which occasionally can come partially undone without your noticing it and then, whoops, you’ve got high blood sugar and pants that smell like bandaids. Awesome.


Second, the Mio’s footprint, as it were, is less conducive to my dreaded insulin donuts. Whereas the Quickset puts pressure on your skin in a way that encourages liquid to pool, the Mio seems to avoid that problem. I’m not sure how, but one possibility is simply that it leaves a slightly larger triangular footprint on your body (without being noticeably larger than the Quickset) — which allows the insulin to disperse more easily into your tissue.


Third, the Mio is cleverly designed to have a built-in applicator. No more dealing with the Quick-Sert (or whatever that thing is called) or the horrendous Silhouette injector that makes you feel like you’re shooting a harpoon into your stomach. This is entirely self-contained, which makes it really easy to pack extras in your purse or glove compartment without having to order separate injection devices or attempt to jab them in by hand. Much better.


The Mio has been available since March 2010, but seems not to have been well publicized, since I’ve spoken with at least 3 doctors/pump educators since then who weren’t aware of it. Hence this blog post: CHECK OUT THE MIO!!!


Additional features:

-it comes with 6- and 9mm cannulas.

-the tubing comes in 18-, 23-, and 32-inch lengths.

-the part that clips into your body comes in clear, pink or blue plastic. Because nothing says “fun” like colored clips on your insulin pump supplies.


As I said, I’ve just started wearing the Mio, so I can’t yet fully vouch for it. But just the applicator alone makes it better than the Quickset. And if I could exist for a month without those donuts? Heaven.

I’m glad to know I’m not the only one with Quickset problems.  So much so that I’ve even contemplated going off of the pump.  I’m going to give these a try and see if I can fall in love with pumping again.

I love the mio infusion sets!!  They are so easy to use.  They don’t hurt that much at all when inserting and I like how everything is self-contained.  Makes traveling and carrying extra sets around much easier.

Thanks so much for this post. I read it last week, called Medtronic to request samples and am now on day 2 of my second Mio. Wore the first one for three days, still got itchy but no “donut”. So far so good with the second one. Thanks again!

Thanks for the comments on the Mio.  It’s good to know there is another alternative for my son, should he want one. My son went on a Medtronic insulin pump at age 12 and had a horrible time with the Quicksets.  Bent cannulas were the least of our problems, though we had plenty of those. For my son, the quickserter was a torture device.  After several months of problems and quickserter anxiety, the pump trainer at his endo’s office recommended the Sure-T. No more bent cannulas. My son claims he cannot feel the needle at all. If the needle does… Read more »

Just FYI you can manually insert the quickest just like you do the sure t! I stopped using the inserter years ago!

Interesting, I’ve always thought that the donut had to do with moisture under the set because it’s not always there.  I’m going to start watching that.  Is there any more info out there on the insulin collecting?

I have 2 kids using the Animas version of the Mio for quite some time, and they are GREAT!
