T/BMA 011-2021 The technical specifications for high-altitude micro-pressure oxygen cabin transportation platform

Scope

Scope: This document specifies the terms and definitions, classification and marking, requirements, test methods, inspection rules, labels, user manuals, packaging, storage, and transportation of plateau micro-pressurized oxygen chambers for transportation. This document applies to plateau micro-pressurized oxygen chambers for transportation (hereinafter referred to as "micro-pressurized oxygen chamber platforms") with a working pressure (gauge pressure) of ≤50kPa, where the pressurized medium is clean air or mixed gases and other breathable gases, used for preventing altitude sickness and for health care, rehabilitation, and similar purposes in high-altitude areas. Main technical contents: This document specifies the terms and definitions, classification and marking, requirements, test methods, inspection rules, labels, user manuals, packaging, storage, and transportation of plateau micro-pressurized oxygen chambers for transportation. This document applies to plateau micro-pressurized oxygen chambers for transportation (hereinafter referred to as "micro-pressurized oxygen chamber platforms") with a working pressure (gauge pressure) of ≤50kPa, where the pressurized medium is clean air or mixed gases and other breathable gases, used for preventing altitude sickness and for health care, rehabilitation, and similar purposes in high-altitude areas. ① Design the oxygen and pressure concentration gradient according to the requirements of indoor space oxygen dispersion (oxygen adjustment) in high-altitude areas specified in GB 35414, to ensure the appropriateness of oxygen and pressure supply, the standardization of supply speed, and the safety of use in high-altitude environments. ② Standardize the oxygen and pressure adjustment rate to ensure comfort and safety during use. ③ Control the oxygen and pressure supply and gradient according to human blood oxygen saturation, to ensure intelligent control of oxygen and pressure supply. ④ Twist-free sub-frame technology i
