PROBLEM TO BE SOLVED: To provide a high pressure room in which by injecting gas other than pure air such as ozone and high concentration oxygen having various kinds of impacts on a human body under high pressure in a chamber, it is expected, for example, to prevent or cure various kinds of diseases when a person enters the chamber.SOLUTION: A high pressure room includes a chamber forming a living space, pressurizing means for raising air pressure in the chamber, and ozone generation means for generating ozone to be injected into the chamber. It also includes high concentration oxygen generation means for generating high concentration oxygen to be injected into the chamber, or switching means for switching the gas to be injected into the chamber between ozone and high concentration oxygen.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 チャンバ内の高圧下で、オゾンや高濃度酸素のような、純然たる空気以外の人体に各種の影響を与える気体を注入することにより、チャンバ内に人が入ることで、例えば、各種の病気の予防や治療が可能となることが期待される。【解決手段】 居住空間を形成するチャンバと、チャンバ内の気圧を上げるための加圧手段と、チャンバ内に注入するオゾンを生成するオゾン生成手段とを備え、また、チャンバ内に注入する高濃度酸素を生成する高濃度酸素生成手段を備えたり、オゾンと高濃度酸素のいずれかをチャンバ内に注入するかを切り換える切替手段を備えたりすることを特徴とする。【選択図】図1
