PROBLEM TO BE SOLVED: To provide a novel oxygen suction appliance for taking dissolved oxygen into a body efficiently.SOLUTION: An oxygen suction appliance 1 comprises: an almost rod-shaped battery part 2 a cartridge 3 having a hollow storage part 31, and detachably connected to the battery part 2 a suction part 4 having a suction port 4a an oxygen dissolution liquid 5 stored in the storage part 31 and heating means 6 capable of heating the oxygen dissolution liquid 5. The oxygen dissolution liquid 5 contains dissolved oxygen which is maintained in a dissolved state in a solution even being heated to 100°C, and steam of the oxygen dissolution liquid 5 generated by heating by the heating means 6 can be orally sucked through the suction port 4a.SELECTED DRAWING: Figure 1【課題】溶解酸素を効率的に体内に取り込むための新しい酸素吸引器具を提供すること。【解決手段】略棒状のバッテリー部2と、中空な収容部31を有し、バッテリー部2と着脱自在に接続するカートリッジ3と、吸引口4aを備えた吸引部4と、収容部31に保持された酸素溶解液5と、酸素溶解液5を加熱可能な加熱手段6と、を備え、前記酸素溶解液5は、100℃に加熱しても溶液中に溶解した状態が維持される溶解酸素を含み、加熱手段6による加熱によって生成された酸素溶解液5の水蒸気が、吸引口4aを介して経口吸引可能とされている酸素吸引器具1とする。【選択図】図1
