Please help?! Calling tandem but no answer. Just changed out carteidge set, and when i put in a new filled cartridge, and pushed “unlock” button or which ever one to start rhe “detecting insulin” phase, RIGHT nefore that phase where you can hear it making noise to detect insulin, i saw some insulin leak out into the pigtail part of wire :o …this was BEFORE you attach longer tube and start ro PRIME it…
I think i had called tandem before about this asking is this OK for jt to leak insulin BEFORE you start to prime it??? I think they said no it shouldn’t leak any into tubing prior to priming it…
It was also was shaking a lot during the detecting cartridge part
Question is,is this OK to leak onsulin into tubing before priming?? Does that mean it’ll just LEAK insulin into YOU at anytime??? And how much? And will it know it did that and alert you? If this leak into tubing wasnt supposed to happen, it didn’t throw an alarm
That is my biggest fear, that itll malfunction and leak /give more to you than should
There are 4 cell types in the islets of Langerhans secreting 5 gluco-regulatory hormones. The islets makes up a very small amount of the pancreas, the majority of the organ is to produce exocrine digestive enzymes.
Someone with a dead or removed pancreas has type 3c panceatogenic diabetes, besides insulin they have to take supplemental digestive enzymes.
Is it possible you tried to fill an old/previous cartridge that still had insulin in it? When I take out old cartridge, I make sure to keep separate from newly filled cartridge.
Another possibility is you overfilled the syringe or just a defective cartridge.
I’ve never noticed insulin leak from the cartridge when I’m “detecting” the cartridge after replacing it. But I always hook up the whole line before proceeding with a new infusion site and cartridge combo. It always seems to take 12 units to “prime” the line.
No I did not overfill the syringe it was only 220 units and it holds 300. I also used a new cartridge for sure. I’m not sure but I think this happens a few times before but at least once before and I called them and they said no that should not be happening at all. So I’m wondering if when it was detecting the insulin and making the noises like a machine would it was shaking a lot as well and shook the pigtail part of the wire. Maybe that caused insulin to leak out usually it doesn’t shake that much. Tandem has been on hold now for 2 hours and they said their company is undergoing maintenance until tomorrow morning. Of course the one time I called them in the year that I need them they are doing maintenance right now. That’s why I am asking on here I’m nervous to use the pump or even put it back on in case it would just deliver more or leak more into me and not know that it’s doing that. I know it’s rare but I have read about these things happening and with my luck it it would do that
You know that warning the pump displays telling you to make sure your infusion set is disconnected from your body? As well as all the similar warnings in the written instructions and video tutorials. That’s because the tubing is already supposed to be connected to the cartridge before you move forward, and if you weren’t disconnected, you’d be pumping all that air and insulin into your body… There shouldn’t be any leaking insulin because that insulin should be going into the tubing.
You seat the cartridge, then screw on the tubing, and THEN click the “next” button, or unlock, or whatever it is at that point.
And no the pump can never leak insulin. The major selling point for tandem before there was any pump automation was it’s unparalleled safety, because unlike other pumps, you are completely separated from all the insulin. (Only Medtronic still employees this “leaky” pump mechanism today, at least in the US) It’s their patented Micro-Delivery feature. Any insulin delivered has to be drawn into an intermediary chamber before it can be pushed into you.
I only put 150in mine but I’ve gone as much as 250. At that point there can be some negative pressure.
I have seen half the entire length of tubing fill from that pressure.
It’s never been a problem for me, but now I fill it less so I do t waste insulin.
You can avoid this by venting the cartridge before you start.
After pushing in the insulin with the syringe, take out the syringe and remove the plunger. Then put it in the cartridge again and it will vent the pressure.
But really you can just let the pressure fill the line.
are you sure you were answering the right question?
