When i filled my tslim cartridge today, it wouldn’t fill the full amount in my syringe. I’m wondering whether I did something incorrectly and whether anyone has had the same thing happened.
The cartridge is brand new. I filled the syringe with insulin, sucked out the air from the cartridge, removed the air bubbles from the syringe and topped it up so that the insulin level was around 290u, and then removed air bubbles once more.
Then began filling up the cartridge. When I got down to about 20 units, the plunger wouldn’t move any more. I pulled out the syringe to check and no visible air bubbles I can see and insulin would come out as I pressed the plunger. So what went wrong?
It’s a pain that you can’t see the inside of the cartridge.
