Title:
EMERGENCY EVACUATION GAS MASK
Document Type and Number:
WIPO Patent Application WO/2018/216998
Kind Code:
A1
Abstract:
The present invention relates to an emergency evacuation gas mask which has a triple wear structure including a silicone tube, a tightening end, and a binding band so that the mask can be quickly worn and has improved airtightness of an opening thereof in the event of a fire. Also, the gas mask has a double structure including an inner membrane and an outer membrane having a spacer interposed therebetween to form a space portion so as to doubly filter poisonous gas, and accordingly enhances filtration performance thereof. Further, the gas mask enables supply of high-pressure oxygen when worn, so that a proportion of carbon monoxide is reduced through the supplied high-pressure oxygen and the high-pressure oxygen having passed through an inner membrane during respiration increases a binding force of oxygen to hemoglobin compared to a binding force of carbon monoxide to hemoglobin.
