【発明の詳細な説明】 （産業上の利用分野） 本発明は潜水用混合ガスの製造方法及び装置に関するも
のである。The present invention relates to a method and an apparatus for producing a mixed gas for diving.
（従来の技術） スポーツ用、業務用潜水中の呼吸用ガスは浅海（0m〜90
m位迄）では空気、深海潜水ではHe/O2,He/O2/N2を使用
している。(Prior art) Gas for breathing in sports and commercial dives is shallow water (0m ~ 90
Up to m), air is used, and for deep sea diving, He / O 2 and He / O 2 / N 2 are used.
空気潜水では空気中の窒素ガスが水深によっては窒素酔
いを起こしたり、密度増加により呼吸抵抗増加による呼
吸困難などの障害を起こし問題となっている。In air diving, nitrogen gas in the air causes nitrogen sickness depending on the water depth, and increases in density cause problems such as respiratory distress due to increased respiratory resistance, which is a problem.
このような窒素酔いや呼吸抵抗の増加を防止するため呼

奪いダイバーが潜水中寒くなるという欠点も出て来てい
る。In order to prevent such nitrogen sickness and increase in respiratory resistance, He / O which replaces the inert gas in the breathing gas with nitrogen from helium
2 Diving is considered and has made many achievements, but this He / O 2
Due to the density of helium, which is the main component of diving, normal conversation can be changed to helium voice, and due to the good thermal conductivity of helium, the diver's body temperature can be taken much more than in the case of nitrogen gas and the diver becomes cold in the diving There are also drawbacks.
50〜100mの中深度短時間潜水ではHe40容量％＋N240容量
％＋O220容量％の方が音声の変化、体温の損失等では優
れており、又浮上時の減圧にもメリットがあることが知
られている。He / she 40% by volume + 40% by volume of N 2 + 20% by volume of O 2 is more excellent in voice changes and loss of body temperature in medium to short-time diving of 50 to 100 m, and also has a merit in decompression during ascent. It has been known.
