摘要： A breathing apparatus provides gas within a hood surrounding a user's head from two oxygen tanks which each utilize a regulator. The first tank serves to inflate the hood while the second provides oxygen to the hood at a sufficient amount for human breathing for a longer time than traditionally available for such hoods. The longer life is provided through the use of micro regulators which utilize micro springs or wave washers and micro machining techniques to regulate the flow of oxygen in a way that has not been previously possible.
