I beleive I have solved my kinking and rolling up. It does not trip me anymore.
First I must tell you that 1) I have COPD. 2) I live in a 2 level town home and I can't go upstair or downstairs because I fall down them a lot. I have to go flown to wash my clothes. But that's another story.
I have a Inogen G3. I love it
Anyway I have used the command small cable holders and hung my tubing on the wall just below the ceiling. That keeps it form rolling up and or kinking.
I also made my own valve that I can shut off the upstairs tubing and open up the one I use to go down stairs. Works well.
Now when I'm downstairs I use the extensions. I used the 7 inch ones. The smaller you get the better it works. Use the connecter to put them together. It may cost a bit more to do this but you don't have to replace them as you due your cannula. Oh if you didn't know you can cut an glue the tubing to make what ever you want or need.
Best thing I've done since I found out I have COPD and conjestive heart problem.
If you have questions please text me.
