Infusion Set

Lack of Back-Up.

1 Comment

I was in the bathroom at work when I first noticed it. A small, deep purple bruise was forming beneath the clear plastic window of my infusion site.

I was a little surprised, given that it had already weathered 24 hours worth of insulin boluses and a good night’s sleep. But I was also not surprised, given it was placed smack bam in the centre of my stomach where I have the least meat on me.

My mind wandered to the pencil case sitting on my desk, however I soon realised that the spare infusion set sitting in there belonged to my YpsoPump. Not a match for the late Animas Vibe I had replaced it with three weeks ago.

My mind wandered to the demi pen and needles that I carry around with me. However, I soon realised that there was no insulin cartridge in there because I’ve been feeling a little paranoid about insulin going bad until recently.

My mind wandered to the Chemist outside, which would probably loan me some insulin if I presented my NDSS card and promised to return with a script. However, I soon realised that it would be wasteful given all of the insulin I had in my fridge at home.

My mind wandered to the low carb chicken salad that I had packed for lunch. However, I soon realised that there were also amazing croutons in there that I had baked with the chicken juices. Not to mention that my blood sugar might also be a little high if the site was failing.

My mind wandered to the needle that was contained in my YpsoPump infusion set. However, I soon realised that there was no way that I would be able to macgyver it to reapply my failing infusion set into a fresh spot.

My mind wandered to my lunch hour, where I would probably have enough time to drive home and come back. However, I soon realised that even though I lived close enough, I could not be bothered rushing there and back and wolfing my lunch down afterwards.

My mind wandered to my Dad, who I felt super guilty for bothering, but who I also knew wouldn’t ever complain about having to deliver an infusion set to me at work.

It’s been a long time since I’ve had an infusion site fail on me well after placing it. I guess in the back of my mind I’ve been putting off updating my travel kit, telling myself it won’t happen. 

I bring my pencil case carrying all of my diabetes back ups with me almost everywhere I go. I hardly ever need to fall back on it when I’m out and about. And yet the one time I do, I don’t have the right stuff in there!

Trialling an Angled Infusion Set

10 Comments

On a grey Saturday afternoon back in July, I was out painting. The rain was pouring down outside. I remember checking my blood sugar level after a perfectly carb counted and pre bolused lunch to find an unexplained high. After I gave an insulin correction with no effect, I lifted up my shirt to find my 6 hour old infusion site bleeding. In addition to those feelings of failure and guilt, my supplies were all the way back at home. I was doubly devastated. Diabetes had ruined my afternoon. I hesitated for a moment, unable to find the words to explain to my brother that I had to take off.

As I drove home in the pouring rain that afternoon, I was on the verge of tears. Once again, I felt failed by my diabetes.

Infusion sites were one of the most overwhelming issues I faced during my first three months of insulin pumping. I spent ages obsessing over where on my stomach my site would be least likely to fail. After every site change, I was left in suspense for hours on end, almost waiting for a site failure. Wondering if the cannula had “clicked” in smoothly underneath my skin, or whether it had kinked. Checking the skin underneath my infusion sites like a hawk, looking for any signs of bruising or occlusions. Worrying about the rapid loss of usable real estate on my stomach, and how much longer I would be able to continue using my beloved insulin pump. I actually felt guilty for the amount of insulin I was using, because more insulin meant quicker onset of site failures.

I was using a 90 degree infusion set with an insertion device at the time. Others had suggested I try a different type of infusion set. I knew that there were different kinds of infusion sets on the market. Ones that went in on an angle, rather than straight in. I don’t really know why it took me so long to look into it. I guess I just thought this was normal. I thought that the site failures were simply a side effect of six years worth of insulin injections. I thought that my body simply couldn’t handle 3 days worth of insulin infusions into the same spot. Besides, it was daunting to try something new.

When I woke up one morning to a bleeding infusion site that I was yet to actually begin using, I knew I had nothing to lose. I grabbed the box of Animas Comfort infusion sets that had been sitting in my wardrobe for a week, and I haven’t looked back since.


This cannula goes into my stomach on an angle, rather than straight in. For starters, I don’t feel it “digging in” when I’m laying on the couch or in bed. On the angle, it doesn’t hit blood vessels and nerves which likely caused the bleeding and site failures so easily. Not having a lot of fat on me probably didn’t help, either…

Yeah, I have to stick a big long needle into my stomach with every site change, but it virtually eliminates the possibility of the cannula kinking on the way in. It’s so much less wasteful, too. If for some reason my infusion set feels uncomfortable after insertion, I can stick the needle back into the infusion set and re apply. Previously, infusion sets were pretty much useless once they came unstuck from the insertion device.

Since I began using the comfort infusion sets a month ago, I’ve had one failed site. The first one. The rest of them have been a breeze. And did I mention that I can actually get them to last the whole three days? Even four? Possibly five…

I keep thinking back to a comment Laddie left me several weeks ago. She mentioned that she couldn’t find a 90 degree infusion set that worked for her. Looking back on my experience, I’m very much inclined to agree. 

I feel so much more comfortable with site changes today. I can change a site and actually get on with my afternoon, rather than stress about it for hours. My stomach is actually starting to look like a stomach and not like some blood stained wasteland. I finally have an explanation for all of the site-related issues I went through, which I can take great comfort in. All those feelings of guilt and failure are gone.

Today I can finally close that book of doubts and confidently call myself an insulin pumper.

Massive thanks to all of you who suggested trialling a different kind of infusion set. I do read and appreciate all of your comments of encouragement. I apologise for being so hesitant to give it a go. I owe you all coffees some day…
