PROBLEM TO BE SOLVED: To provide a self-contained underwater breathing apparatus configured to improve economic efficiency for one dive and achieve power saving of background equipment for operation.SOLUTION: The self-contained underwater breathing apparatus includes a secondary battery 15 and a plant 15. A diver can continuously breathes through a mouthpiece 1 by means of power from the secondary battery and photosynthesis of the plant. The following are basically consumed for actuating the apparatus: power to be supplied from an arbitrary power source to the secondary battery moisture to be supplied to the plant when the apparatus is in operation or when it is not in operation on land or a boat and compressed air to be supplied from an arbitrary compact air compressor to a compact tank 14 having an auxiliary function, such as bail-out, connected to the apparatus.COPYRIGHT: (C)2013,JPO&INPIT【課題】自給式潜水器の一回潜水毎の経済性の向上、運用上の背景設備の省力化。【解決手段】自給式潜水器内に2次電池15、植物15を配置し、潜水実施者は、その2次電池の電力と植物の光合成能力でマウスピース1からの連続の呼吸を可能とし、その装置の作動に必要な消費材は基本的に、任意の電力源からの2次電池へと供給される電力と、装置作動時、また、陸上、船上等で装置作動時以外に植物に供給される水分、そして装置に接続されているベイルアウト等の補助的機能を持つ小型ボンベ14に供給される任意の小型空気圧縮機からの圧縮空気のみとする。【選択図】図1
