Abstract

本装置是关于口罩，特别是防水汽口罩的发明。这种口罩的上沿内面，缝有一块乳胶薄膜，在其与口罩所成的腔隙中塞有一块鼻形海绵垫，当戴眼镜的医务人员或者其它工作人员戴上这种口罩后便不会因口中呼出的水蒸汽蒙住镜片而影响工作。

Description

本发明是关于口罩，特别是防水汽口罩的发明。该口罩由纱布垫、鼻形海绵垫及口罩带构成。
目前普遍使用的口罩不具有防止水蒸汽蒙住眼睛片的作用。
本发明的任务是提供一种防水汽口罩，使其具有防止水蒸汽蒙住眼睛片的作用。
其解决方案是：在口罩上沿内面缝制一个垫子，堵住口中的水蒸汽上升。
附图描述了本发明的原理。
附图1：一块折好的纱布；
附图2：一块连有医用胶布的乳胶薄膜；
附图3：鼻形海绵垫；
附图4：口罩成品图；
图1所示为一块折好的纱布垫，1与3分别为纱布垫的两个边，2为折线。
图2所示为一块连有医用胶布的乳胶薄膜，6所示医用胶布贴在乳胶薄膜上。将6粘带5，以6为基准沿图1中1所示的边贴在上面，然后用缝纫机沿6缝制，使得6与5连在图1所示的纱布垫上。再将5沿缝纫机从6上走过的机线向下折，再将图1中3所示的纱布垫的边以2示折线向上折，使图1中3示的边恰好压在图2中4示的乳胶薄膜边上，复以缝纫机缝制。
图3所示为一鼻形海绵垫，将其正面（7示）向上从乳胶薄膜与纱布垫所成的腔隙中塞入即可。
图4所示为该发明成品图。
通过包有乳胶薄膜海绵垫的堵塞作用，可以使眼镜片免受口中呼出的水蒸汽影响。
