Abstract
The invention discloses a device for long-time oxygen supply and protection for life saving in a fire disaster. When a fire disaster occurs, a firefighter wearing the device of the invention can enter a fire scene as if entering a fireless scene to rescue persons who fail to escape from the fire within two hours. When a forest fire occurs, the firefighter wearing the device can continuously attack the fire (without worrying about lack of oxygen, suffocation), thus the device is beneficial to fire suppression. The device provided by the invention is characterized by a nasal mask for breathing since the nasal mask can directly convey CO2 breathed out by the firefighter to the bottom of oxygen generating agent and the oxygen generated from the reaction of CO2 and the oxygen generating agent can be directly pumped into an oxygen inhaler for oxygen intake. In addition, the device can supply oxygen for two hours under the emergency of fire suppression.
Description
Technical field
The invention belongs to fire lifesaving field.
The present invention relates to when fire rescue, on-the-spot big fire is fiercely burnt, and passage is sealed by big fire.Still have the people who has little time to escape in the scene of a fire, situation is critical very much.At this moment the fire fighter puts on the present invention, just can as go into not have the border of fire.The random scene of a fire of coming in and going out.The personnel that besieged by big fire are all rescued.The big fire though the fireman repeatedly comes in and goes out.Even, but still can the person of outstanding talent send out the harmless fire rescue task of finishing smoothly for up to 2 hours.
Certain forest is on fire suddenly, and the intensity of a fire is fierce, puts out as untimely, and the intensity of a fire is overflow and fired.Might form and spread all over thousands of hectares fire.At this moment the fire fighter is on the scene, and puts on the present invention, picks up branch, fiercely swat big fire, owing to the invention provides the condition of fire fighter's oxygen uptake when long, the personnel of putting out the fire needn't take inflammable into account and breathe, merely swat always,, finally big fire is put out at the beginning of sprouting fiercely swatting down of everybody.
Background technology
To the rescue of big fire, there have been a lot of methods, measure, instrument and apparatus in the human culturally advanced society of modern times that arrives.Just there are water, sand and carbon dioxide in the extinguishing chemical aspect.Up to now use is the most cheap at most, the most effective water that remains.Fire-fighting vehicle, the fire fighting aircraft all is that water is spilt to the scene of a fire, is used to put out big fire.
When fire took place, some people had little time escape as: woman, children, old, sick, residual person, has been besieged by big fire.At this moment the fire fighter is with face shield, and back oxygen cylinder and so on pours the scene of a fire and rescues the people.It is reported in Hengyang and the Urumchi fire rescue, all have the fire fighter to sacrifice, see that from the fluorescent screen sergeant Zhu Xiaolei that sacrifices in the fire of Urumchi pours the scene of a fire and rescues man-hour, choked to death because of anoxic.General fire fighter enters scene of a fire lifesaving, breathes if can not get oxygen, will be choked to death.Thereby the oxygen supply in the fire lifesaving is exactly a key issue.
Modern method for producing oxygen through is divided into two classes.One class is to be raw material with the air, produces or by zeolite molecular sieve the difference of oxygen, nitrogen adsorption capacity the air is realized that oxygen, nitrogen separate and produce from the liquid air fractionation as industrial.The oxygen that the former produces all uses hig pressure storage in steel cylinder.The latter's method for producing oxygen through has derived many kinds of trade mark medical oxygen generators, and also some oxygenerator is made power supply with dry cell.Another kind ofly produce oxygen with peroxide or oxide and catalyst reaction.As laboratory system oxygen, be total to thermal response with potassium chlorate and manganese dioxide exactly and produce.Curable product oxygen is upright, is exactly with hydrogen peroxide and manganese dioxide reaction system oxygen.Oxygen can be produced with suitable method in a lot of oxides and peroxidating field.
With high pressure oxygen is stored in the steel cylinder, can high pressure to 15 atmospheric pressure during oxygenation, but after placing a period of time, pressure can reduce gradually even to 0, the oxygen in the steel cylinder " has disappeared suddenly " because of infiltration leakage.If fire fighter's this moment uses the very early steel cylinder oxygen supply that is full of oxygen to pour the scene of a fire and rescues the people, be difficult to from the scene of a fire, live.Just be full of 15 atmospheric steel cylinders and pour the scene of a fire disaster relief even carry do oxygen supply.Just in case steel cylinder is met thermal explosion, consequence is with hardly imaginable.Use medical oxygen upright (by two kinds of chemicals reactions of A, B system oxygen), be not easy to control very much reaction speed.In emergency circumstances this in fire fighting, be unfavorable.Use the oxygenerator of the various trades mark of modern medical service, from air, separate system oxygen with molecular sieve, impossible especially, because the airborne oxygen in the scene of a fire is burned.These all are that current fire rescue enters the weak link that people's fire-fighting oxygen-supplying technology is rescued in the scene of a fire.This just weak link has caused Hengyang, Urumchi fire, fire fighter's sacrifice.
Fire fire fighting device of the present invention is created for the weak link that overcomes prior art just.Used system oxygen species, long term storage can not decomposed, chemicals (3kg) and the CO that breathes out
2The oxygen that reaction is emitted enough supports an adult to breathe 2 hours.Can satisfy in the fire fire fighter enters the scene of a fire and rescues human needs.
Summary of the invention:
The objective of the invention is to, when fire takes place, provide a kind of apparatus to the fire fighter, put on this apparatus after, the oxygen that can gain freedom the long period and breathe.Thereby the scene of a fire of can arbitrarily coming in and going out is rescued by big fire and is besieged the people who has little time to escape.Perhaps in the forest scene of a fire, put out continuously from the beginning of big fire.
Oxygen supply of the present invention is the helmet of the sealing of a circle, and the front of the helmet is transparent visual.The nose cup at middle part is connected by the chemicals device of two tracheaes with system oxygen.The nose cup place is connecting expiration (CO
2) pipe and air-breathing (O
2) pipe.The expiration mouth of pipe is bumped into the square cushion chamber of 1cm, and the cushion chamber another side is being inlayed tracheae, at the bottom of the straight-through oxygen-making agent bottle.The one side that tracheae enters cushion chamber is equipped with cushion compound (valve of living) and is keeping off the mouth of pipe, and during expiration, the valve of living is washed open CO
2Enter and arrive oxygen-making agent by tracheae, emit oxygen with the oxygen-making agent reaction, the cushion compound of air intake duct cushion chamber dress (valve of living) position is on the air feed mouth of pipe.When air-breathing, inhale the O of coming
2Gas is washed cushion compound open, O
2Suck in, at this moment CO
2Pipe valve alive cuts out, in case CO
2By suck-back.So form and breathe circulation smoothly.
The oxygen-making agent of selecting is Li

The specific embodiment
The invention is characterized in that rescue among the people at fire, the fire fighter puts on the present invention, just can in 2 hours, obtain the oxygen of happy breathing.Arbitrarily the discrepancy scene of a fire will be besieged the personnel that also have little time to escape by big fire and be rescued or must enter other rescue tasks that the scene of a fire could be implemented.
Feature of the present invention also is, when putting out a forest fire.The personnel of putting out the fire put on the present invention, the oxygen that just can in official hour, gain freedom and breathe, and person of outstanding talent's nothing is taken ground into account, swats raging fire continuously.Directly cause big fire is put out.
The present invention has use value under the anaerobic environment of exploring and climbing the mountain.
The present invention also can substitute the indeterminable or temporary transient indeterminable difficult problem of other oxygen-supplying technologies in health care.
