针对高原地区哨位战士站岗缺氧问题,依据变压吸附制氧基本原理,设计一种适合高原地区哨位使用的小型供氧机.结果表明:产品气的氧体积分数始终在70%以上,最大流量始终在6 L以上;提高了血液中的氧质量分数,可以为各个组织器官提供更多的氧气,供氧机在高原低氧环境下可以提高机体的抗缺氧能力;在高原环境条件下使用供氧机可以降低心率,能够起到保护心肌的作用,特别是随着海拔的升高,这种保护作用越明显.
According to the basic principle of pressure swing adsorption oxygen production, a small oxygen supply machine is designed for the use of the whistle in the plateau area.The results showed that the oxygen content of product gas is always above 70%, and the maximum flow rate Always above 6 L; improve the blood oxygen mass fraction, can provide more oxygen for all tissues and organs, oxygen supply machine can improve the body’s anti-hypoxia ability under high altitude hypoxia environment; use in high altitude environment The oxygen machine can reduce the heart rate, can play a role in protecting the myocardium, especially with the elevation of this protective effect is more obvious.
