Oxygen cylinders are often used in case of hypoxia condition and emergency.
The capabilities of existing oxygen cylinders, however, are limited ,which
causes danger because of oxygen cylinders without enough oxygen. With a
principle that carbon dioxide reacts with sodium peroxide oxygen ,this design
changes the original principle which makes the breathing gas recyclable ,therefore,
produces oxygen continuously. Furthermore, it will greatly increase the oxygen capabilities,
so as to guarantee people's security to a great extent.
