AIR DIVISER / portable air respirator

Based on consideration of existing problems reported regarding air supply by existing add-on air respirator, this 'air diviser' is designed to be a portable air-breathing apparatus that allows oxygen of approximately 10L to be separately contained from fire fighter's, which is intended to be consumed by rescuee. This can be taken as an improved version of existing air respirator model, which is capable of providing people as many as possible with sufficient amount of air so as to help fire fighting and rescuing survivors more rapidly.
