To develop a portable oxygen moisture bottle. The bottle adopted a double-tightened and separate structure, whose shell was made of transparent materials. The inner liner was made of PTFE hydrophobic mem-brane filter, which applied a 3-layer structure to inlet oxygen into the shell through the air membrane filter at all directions. The bottle had no requirements for site and high reliability, and the desired use for continuous oxygen inhalation was realized. The bottle has a simple structure, low cost, easy maintenance and high portability, and gains ad-vantages over the traditional one.
