Abstract

一种传染病护理用防护口罩。主要解决现有口罩当戴眼镜的医护人员佩戴时经常会发生呼出的气体导致眼镜片出现蒸汽的问题。其特征在于:口罩面主体内固定有一个鼻形托架,鼻形托架上开有一个过气通道和若干通气孔,通气孔位于鼻形托架上模拟鼻孔处;口罩面主体上分布有由多层医用无纺布制成的鼻呼吸区和口呼吸区,鼻形托架上的过气通道与鼻呼吸区相连通;在鼻呼吸区和口呼吸区的外层布料与内层布料之间填充由活性炭纤维制成的过滤芯布。该种口罩内置有鼻形托架并开有导气孔与位于口罩上的过滤通道相连通,因此,可以将气体直接呼出口罩外,避免呼出的气体从口罩上方落到眼镜片上,便于戴眼镜的医护人员使用。

Description

传染病护理用防护口罩
技术领域
 本实用新型涉及一种医用防护用品,具体的说,是涉及一种用于传染病内科护理中的口罩。
背景技术
在完成传染病内科护理工作时,医护人员都需要佩带口罩以防止传染物通过呼吸道进入人体。考察现有的口罩,一般都是采用中央突起的结构,但是这种结构明显存在一个问题,就是当戴眼镜的医护人员佩戴时经常会发生呼出的气体导致眼镜片出现蒸汽的问题,在冬天还常常导致眼镜片上霜。
发明内容
为了解决背景技术提出的现有技术中存在的问题,本实用新型提供了一种传染病护理用防护口罩,该种口罩内置有鼻形托架并开有导气孔与位于口罩上的过滤通道相连通,因此,可以避免呼出的气体从口罩上方落到眼镜片上,便于戴眼镜的医护人员使用。
本实用新型的技术方案是:该种传染病护理用防护口罩,包括由不透气材料制成的口罩面主体和由弹性材料制成的紧固带,其独特之处在于:
所述口罩面主体内固定有一个鼻形托架,所述鼻形托架上开有一个过气通道和若干通气孔,所述通气孔位于鼻形托架上模拟鼻孔处;所述口罩面主体上分布有由多层医用无纺布制成的鼻呼吸区和口呼吸区,所述鼻形托架上的过气通道与鼻呼吸区相连通;在所述鼻呼吸区和口呼吸区的外层布料与内层布料之间填充由活性炭纤维制成的过滤芯布。
本实用新型具有如下有益效果:该种口罩内置有鼻形托架并开有导气孔与位于口罩上的过滤通道相连通,而鼻形托架上的过气通道又与鼻呼吸区相连通。因此,医护人员使用时,只要将鼻形托架对应放置在鼻孔处,就可以将气体直接呼出口罩外,避免呼出的气体从口罩上方呼出,从而不会落到眼镜片上,也就不会导致镜片结霜,便于戴眼镜的医护人员使用。
附图说明:
图1是本实用新型的整体结构示意图。
图2是本实用新型所述鼻形托架的结构示意图。
图中1-口罩面主体,2-口呼吸区,3-密封边,4-鼻形托架,5-鼻呼吸区,6-紧固带,7-过气通道,8-通气孔。
具体实施方式:
下面结合附图对本实用新型作进一步说明:
如图1结合图2所示,该种传染病护理用防护口罩,包括由不透气材料制成的口罩面主体1、密封边3和由弹性材料制成的紧固带6,其独特之处在于:
所述口罩面主体1内固定有一个鼻形托架4,所述鼻形托架4上开有一个过气通道7和若干通气孔8,所述通气孔8位于鼻形托架4上模拟鼻孔处。所述口罩面主体1上分布有由多层医用无纺布制成的鼻呼吸区5和口呼吸区2,所述鼻形托架4上的过气通道7与鼻呼吸区5相连通;在所述鼻呼吸区5和口呼吸区2的外层布料与内层布料之间填充由活性炭纤维制成的过滤芯布。
该种口罩在使用时,需要将鼻形托架对应放置在鼻孔处,就可以将气体直接呼出口罩外,避免呼出的气体从口罩上方呼出。
