Novapen 6 falls apart

[MuttNJeff]

Several times when I have picked up my novapen 6 it has come apart and the plunger retracts fully. Apart from lacking a reliable way to fix the part which holds the cartridge, this wastes a lot of insulin getting the plunger far enough advanced to prime a cartridge wich has been in use for some time.

Tonight I ejected the last units from an old cartridge (not enough for the dose), unscrewed the needle, opened the pen, removed the cartridge and then discovered there was nothing for a needle to screw onto.

Is it only me, or are these of very poor quality manufacture ?

screws onto the cartridge itself which protrudes slightly from the pen after inserted or at least does with the nova echo

Thanks, I panicked. Pedantically, the cartridge doesn't seem to actually have a thread.

What brand insulin does it say on the cartridge?

the threads for penfill cartridges are usually pretty small heres a couple images of mine. the threads don't go all the way around, just mostly and hard to see (maybe as i cba to put on my glasses)

Hello @MuttNJeff , this problem with the pen falling apart, I had it happen a couple of times. It was because I screwed the needle in too tight. So when I changed the needle it opened the pen, so when I got the pen for the next injection it was now in two pieces. So once aware of the problem I now hold the bottom half of the pen when changing needles. Like you I had to adjust the pen to get it to work after it had been apart. So take care changing the needle. I am sure others have found this problem.
