My brother of 13 years has had asthma since he was born. His spacer for meter dose inhaler (MDI) is very big, dificult to transport and wash.
Tubee is a totally new concept for a spacer for MDI patients. Previous products aren't portable and being a large balloon-like piece of hollow transparent plastic, many find them cumbersome to carry around and they can worry small children when they first learn to use them.
More affordable for children, "Tubee" could be transported in the kid's bag. Additionally, the kids will have found a cool product because the variety of colors that can be placed in the different parts will not have that problem more.
