ABSTRACT:
A novel respirator including a chemical cartridge for reacting with moisture and carbon dioxide in exhaled breath to produce oxygen. The oxygen is stored in a breathing sac. The breathing sac communicates with the chemical cartridge through supporting pipes and a channel formed between the outer wall of the chemical cartridge and the inner wall of an associated container. The cartridge and its associated container are positioned on the bottom of the respirator such that the user has ready access to a spent cartridge so that it can be removed quickly and easily and replaced with a fresh cartridge.
