Not sure but but I think there is a carrier on wheels that may help - You would have to be very coordinated though to push wheel chair and roll oxygen at same time!! I did this for my mom though. she was the one in wheel chair and on the oxygen. I just held the handle of oxygen and wheelchair with one hand. The portable pack seems like the best idea if it will hold enough for your trips with daughter. Take care and I hope you find something that works for you.
