I am brand new to this list and so excited I found it!

I've been taking care of my mom who is going to be 95 this August (god willing...).  Mom is  obviously frustrated with her oxygen line everywhere and I am worried she'll fall especially being on blood thinners like she is.  These trip hazards have become as much as detriment to her as it is to breathe.  I am looking for a retractable oxygen line that will work for her.  She is on full-time oxygen and cannot carry the device showing on the YouTube video that you wind up.  

Can anyone suggest another device that works?  I am not only worried about her falling, but also that i have three mini-dachshund puppies and am hoping and praying they don't chew through her lines when she moves in with me.  Having a retractable device would be most helpful.

Thank you in advance.
