About Us

This tool exists because I got fed up with bent cannulas.

I'm a Type 1 diabetic and insulin pump user. Like a lot of pump users, I kept running into the same frustrating problem — unexplained high blood sugar hours after a fresh infusion set change. I'd bolus, nothing would happen, and eventually I'd figure out the cannula had bent during insertion. Another wasted set. Another disrupted day.

I knew the culprit was tenting — the way the introducer needle drags on the tape and skin as it's withdrawn, pulling the soft Teflon cannula partially out of position. The fix seemed simple: just hold the tape flat while the needle comes out.

So I tried a butter knife. Slid it alongside the cannula hub, pressed down on the tape, withdrew the needle. It worked.

Then I made a fork work — removed a couple of tines, bent it to fit around the hub. That worked even better.

My grandson saw what I was doing and said: "Pop, just 3D print that and sell it."

So I did. I designed the Cannula Tape Securing Tool specifically to fit around the hard cannula hub and press down on the tape and surrounding skin during needle withdrawal — keeping everything flat, preventing tenting, and keeping the cannula fully seated where it belongs.

It works perfectly. I use it every single infusion set change.

I built Diabetic Depot to get this tool into the hands of every pump user who's ever stared at a rising CGM trend line and wondered why. Now you know why — and now there's a fix.
