After reading multiple posts by Zoe and others about how much they like Contact Detach sets (Medtronic Sure-T), I recently ordered a box as part of my last pump supply order. To tell you the truth, I didn't do much homework about them and was a bit dismayed to find that they are just metal versions of 90 degree sets such as Insets, Mios, and Quicksets.
I have used two sets so far. I didn't mind the insertion and wasn't too annoyed by having two adhesive patches. I always plan my pump sites so that I never lay on them while sleeping. When my Dex G4 site is on my right side, I use my right side for pump sites and sleep on my left side for the 2-3 weeks of the sensor life. When my sensor is on the left, my pump sites are also on the left and I sleep on my right side. My first Contact Detach site hurt a bit and ended up having blood showing 3 inches in the tubing after 24 hours. So that one was abandoned. The second one lasted a day and a half before it completely lost its adhesive and I discovered it loose in my underwear. Fortunately it was quickly found before I went too long without insulin!
I have always done poorly with straight-in sets. I'm not as thin as I used to be, but I am still somewhat thin and tend to get pain, bruising, and poor results with 90º sets. For some reason I expected the Contact Detach sets to have a very short metal needle. Unfortunately it is just as long as the teflon tubes of the other 90 degree sets.
One thing I did like about my two Contact Detach sets is that right away I had great absorption of my insulin. I use manually inserted Comfort Shorts (Medtronic Silhouettes) and tend to have highs after insertion unless I use a huge prime and extended basals for an hour or two.
I will use my remaining Contact Detach sets. Right now I have two bruises from the two sets that I have used. In a few weeks, maybe I will have ten bruises! So back to my Comfort Shorts. Maybe they can design an angled set with a metal needle. Until then, I'll stay with what works...
