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?
