【摘要】 文章通过正压氧气呼吸器与普通氧气呼吸器的结构和应力分布比较,进一步对正压氧气呼吸器呼吸系统的静态和动态应力分析,从而展示了它的优越性。实践证明其呼吸防护能力优于普通氧气呼吸器;在正压呼吸条件下呼吸,对人体的呼吸器官和循环系统不会产生任何不良影响。更多还原

【Abstract】 Compared the structure and stress distribution of positive pressure oxygen respirators with common oxygen respirators, dynamic and static stress analysis was further carried out, thus showingits superiority, it is proven that its protective capacity is better than the common oxygen respirators, under the condition of positive pressure breathing conditions, no side effect was caused to breathing organ and circulatory system.更多还原
