Description
技术领域
本实用新型涉及一种逃生救援口罩,是一种特别适用于在火灾、有毒环境中逃生使用的辅助防护工具。
背景技术
火灾具有突发性、多发性、反复性和多变性的特点,近几年来,我国每年发生火灾约4万起,死亡2000多人,伤残3000-4000人,直接关系到人们的生命财产安全和社会的稳定与发展。在火场中,由于逃避不及时被烟雾引起窒息是火灾致伤、致死的主要原因。现场死亡者绝大多数是因为烟熏窒息、中毒而死的。
火灾中烟气的主要成分是碳粉,还有大量的一氧化碳、二氧化碳、硫化氢等有毒气体,对人体危害很大。烟雾和毒气无孔不入,而且流动性强,在高层建筑中,失火时烟气的水平平均流速为0.3~0.8m/s,垂直方向的扩散速度为3~4m/s,当烟气无阻挡时,在1分钟内烟气扩散到几十层的高程大楼,烟气的扩散流速大大超过人的疏散速度。有时人们在还没有来得及发现火光之前,就已深受其害,当烟气的浓度超过1.28%,人在三分钟内就会失去行动能力,造成窒息、休克、以致中毒死亡。火灾时被浓烟熏呛致死的人数,往往是直接烧死的几倍。有资料显示,火灾时因缺氧、烟气侵害而造成的人员伤亡可达火灾死亡人数的50--80%。
因此,如何防范火灾烟气,对人们逃生至关重要。最简便的方法是-毛巾防烟法。毛巾折叠起来后捂住口鼻就会起到很好的防烟作用。若将干毛巾折叠16层,烟雾消除率达90%以上,含水量在本身重量的3倍以下的湿毛巾效果更好。但事实上在遇到火灾时大多数人手边没有毛巾等的同类物品,不具 备使用湿毛巾逃生的条件!
并且在火灾发生时,人们普遍会产生恐惧心理,尤其当火灾产生的浓烟导致方向不明时,越发使人感到恐惧无助,使人失去理智和行动能力,无法正常疏散,甚至相互挤压、踩踏,堵塞逃生路径,最终造成群死、群伤。
发明内容
本实用新型所要解决的是在火灾、有毒现场有效解决因烟气侵害而造成人员伤亡的难题,为遇险人员有效增加逃生机会。
本实用新型所采用的技术方案为:一种防浓烟逃生口罩,其特征在于:口罩本体,由10层医用无纺布和两层过滤棉叠加而成、正面上部有反光带、正面上部有聚烯烃树脂环保鼻梁夹、两侧有松紧带,所述防浓烟逃生口罩使用时为溶液侵湿状态。
本实用新型的防浓烟原理为湿毛巾防浓烟原理,所述防浓烟逃生口罩使用时为溶液侵湿状态,侵湿的口罩本体由10层医用无纺布和两层过滤棉叠加而成,这样能充分吸附和过滤烟毒。同时侵湿溶液由每升水中溶解0.2~0.4克的醋酸氯己定、0.03~0.05克的薄荷脑、0.07~0.09克的冰片、0.1~0.2克的甘油制成,这里命名为“清脑溶液”,这样的成分配比,能使遇险者冷静下来,还可以隔绝高温气体、避免热气流对呼吸系统的灼伤和损害,增加逃生机率,“清脑溶液”由薄塑料密封包装,放在口罩整体包装内,便于长时间保存和随时取用。醒目的口罩反光标识,便于在黑暗中逃生人员相互确认位置,并有利于搜救人员及时发现。
附图说明
附图1是本实用新型逃生救援口罩的结构示意图。
1为逃生救援口罩本体 2为逃生救援口罩两侧的松紧带
3为逃生救援口罩上的反光带 4为逃生救援口罩上的聚烯烃树脂环保鼻梁夹
