Today I’m concluding my 6 day test drive of the Inset II infusion set (also known as Inset in some markets). It’s been an interesting experience, specially considering that is the first non-Medtronic set that I try in my Minimed Paradigm 522.
These infusion set is manufactured by Unomedical, but is also marketed by Animas. It is available in three colors here in Australia (Blue, Pink and Grey) although a fourth color seems to be available in the USA.
For me, the biggest positive of this set was the integrated inserter. In the past, I’ve had some issues with infusion sets getting stuck to the reusable inserter. By using an integrated, single use inserter, I’m sure to get a perfectly placed, always working set.
The set is small and compact and easy to keep around, specially good if you want to carry in your bag. It was also good to see that once you have completed the insertion, you only need to put the cap back on and throw in the garbage bin. No need for a sharps container as the needle stays enclosed, great specially if you need to do an emergency change on the road.
There are a number of things that I didn’t quite like about this set. Having a single use inserter means that the quality and feel of the device is not as good as some of the reusable ones. In particular, the Inset does not use a spring to shoot the needle in but instead, it creates tension by twisting some of the plastic. This also means that the insertion is not as precise as it should, which ultimately increases the risk of a painful insertion.
I also didn’t like the connector on the set. Instead of the twist off motion on other sets, the Inset uses a straight pug, which I found hard to connect and disconnect.
The adhesive is a bit smaller than some of the other sets, and seemed to be more affected by water from the shower. That said, it lasted the full 3 days without any issue. This, however, may be more of a problem for those who wear their sets for longer.
While so far I really like these set, I will probably not continue using them in the long run. For much that I like the concept of an integrated single use inserter I really value the precision on the insertion movement.
I have, however, decided to keep a couple of these sets in each of my emergency kits, as they would come handy in case I need to change my set while away from home.
