Anti-kink for oxygen hose

thingiverse

I designed this device while working for an oxygen supplier. As I was setting up a humidifier atop a concentrator, the tube extended from the cap of the reservoir down to the front of the machine. Over time, however, the tube developed a bend due to its straight ascent out of the bottle and its connection point below it. This simple fix involves sliding a small sleeve over the top of the humidity reservoir's hose.
