Abstract

The utility model provides a heavy-smoke-preventing escape mouth mask, and provides a fire hazard rescue assisting tool for preventing casualties caused by flue gas invasion in fire hazard fields and advantaged by convenient carrying and wearing. The heavy-smoke-preventing escape mouth mask comprises a mouth mask body, elastic cords disposed at the two sides of the mouth mask body, and a ''cephalocathartic solution'' sealing bag, the upper part of the outer surface of the mouth mask body is provided with a reflective tape and a polyene resin environmental protection nose bridge clamp, the mouth mask body is formed by superposition of ten layers of medical non-woven fabrics and two layers of filter cotton, the ''cephalocathartic solution'' comprises various traditional Chinese medicine components capable of refreshment, and can effectively alleviate nervous emotion, the whole is in a sealing packing via an aluminum foil composite thin film. The heavy-smoke-preventing escape mouth mask is advantaged by convenient wearing, effects of filtering toxic flue gas and calmness, insulation of high temperature gas, prevention of burn and damage of thermal current upon a respiratory system, and facilitation of mutual position confirmation of escapers in dark and timely discovery by rescuers due to eye-catching mouth mask reflecting marks.

Description

Anti-dense smoke escape mouth mask

Technical field

The utility model relates to a kind of escape and rescue mouth mask, is a kind of auxiliary protection tool that escape is used in fire, poisonous environment that is specially adapted to.

Background technology

That fire has is sudden, multiple, the characteristics of repeatability and polytropy, in recent years, about 40,000 of the annual breaking out of fire of China, dead people more than 2000, wounded or disabled 3000-4000 people is directly connected to people's the security of the lives and property and the stable and development of society.In the scene of a fire, caused that by smog suffocating is the main cause that fire is caused injury, caused death because escape is untimely.The on-the-spot dead person overwhelming majority because of sootiness suffocate, poisoning and dead.

The main component of flue gas is a carbon dust in the fire, also has toxic gases such as a large amount of carbon monoxide, carbon dioxide, hydrogen sulfide, and is very big to human harm.Smog and poison gas are all-pervasive; And mobile strong, in skyscraper, the horizontal mean flow rate of flue gas is 0.3～0.8m/s when catching fire; The diffusion velocity of vertical direction is 3～4m/s; When flue gas was unobstructed, Flue Gas Diffusion was to the elevation building of tens layers in 1 minute, and the diffusion flow velocity of flue gas substantially exceeds people's evacuation speed.Sometimes people are not before also having enough time to find flame, just deeply hurt, and when the concentration of flue gas surpasses 1.28%, the people will lose ability to act in three minutes, cause and suffocate, suffer a shock, consequently be poisoned to death.Smoked the deadly number of choking, several times of directly burning to death often by dense smoke during fire.Have data to show, the casualties that causes because of anoxic, flue gas infringement during fire can reach the 50--80% of fire fatality number.

Therefore, how to take precautions against fire smoke, it is most important that people are escaped.The easiest method is-the towel smoke prevention.Cover mouth and nose after towel is folded up and to play good Smoke prevention effect.If with folding 16 layers of dry towel, the smog elimination factor reaches more than 90%, water content is in the wet towel better effects if below 3 times of weight own.But in fact most of people do not have the ware of towel etc. on hand when running into fire, do not possess the condition of using the wet towel escape!

And when fire took place, people generally can produce the feared state of mind, when the dense smoke that especially produces when fire causes direction to be failed to understand; It is helpless that the people is quailed; The people is lost one's marbles and ability to act, can't normally evacuate, even mutual extrusion, trample; Stop up best-effort path, finally cause dead, group wound of crowd.

Summary of the invention

The utility model is to be solved to be effectively to solve a difficult problem that causes casualties because of the flue gas infringement at fire, poisonous scene, for distress personnel effectively increases the escape chance.

The technical scheme that the utility model adopted is: a kind of anti-dense smoke escape mouth mask; It is characterized in that: the mouth mask body; 10 layers of medical adhesive-bonded fabric and two-layer filter cotton be formed by stacking, front upper has reflective tape, front upper has vistanex environmental protection bridge of the nose folder, there is elastic cord both sides, invades wet condition as solution when said anti-dense smoke escape mouth mask uses.

The anti-dense smoke principle of the utility model is the anti-dense smoke principle of wet towel, invades wet condition as solution when said anti-dense smoke escape mouth mask uses, and invades wet mouth mask body and is formed by stacking 10 layers of medical adhesive-bonded fabric and two-layer filter cotton, can fully adsorb and filter the cigarette poison like this.Invading wet solution is simultaneously processed by the menthol of the chlorhexidine acetate that dissolves 0.2～0.4 gram in every premium on currency, 0.03～0.05 gram, the borneol of 0.07～0.09 gram, the glycerine of 0.1～0.2 gram; Here called after " cephalocathartic solution "; Such composition proportion can make the person in distress cool down, and can also completely cut off high-temperature gas, avoid thermal current burning and damaging respiratory system; Increase the escape probability; " cephalocathartic solution " is packed by thin plastic seal, is placed in the mouth mask entire package, is convenient to long-time preservation and takes at any time.Eye-catching mouth mask reflecting marking is convenient in the dark that the escape personnel confirms the position each other, and helps the rescue worker and in time find.
