Description

Life saving mask for subsequent use in car

Technical field

The invention belongs to escaping tool for subsequent use in automobile.

Technical background

Automobile generally travels on the ground, but in the river rushing in roadside because of unexpected sometimes or pond, is therefore drowned the thing of people in car and often occurs.In current car, escape apparatus is helpless whatever except preparing bell.

Automobile is rushed in suddenly in water, what front and back there occurs on earth in car? brave is had in person car to be left to be flushed in river from bridge and put into practice: if car body does not have seriously impaired, water can be intake from surrounding gap, compartment, is flushed to water fills to water the time that whole compartment generally wants more than one minute from car.Before water does not fill compartment, if people opens car door or batters down vehicle window, water at once can gush and enter people wash from outlet until fill compartment submergence human body.Somebody at this time can not hold the breath and touch out compartment escape, and most people is all can't help breathing, but inspiration is water entirely, struggles until shock death so painful.

Summary of the invention

Can successfully escape to make the people in the unexpected automobile be flushed in water, life saving mask for subsequent use in a kind of car of my invention, its weight is little, it is little that what wrinkle got up to lay at ordinary times take volume, when car is rushed in water time, even if people is submerged by water, people also can obtain oxygen number minutes from mask thus make people can composedly open calmly car door or batter down vehicle window to get out to climb up on top of the water car and draw bank again this mask cover on head people's very first time.

The technical scheme that mask technical solution problem of the present invention is taked is: tighten on formula rubber face mask at one and tie up one or several compressed oxygen bottle attached, compressed oxygen bottle go out the position, nostril that oxygen small hose leads to people, rubber face mask also stay face position opening make people can from the gas that spues in the mouth, when automobile is rushed in water, just can from nostril take in oxygen from body gas of breathing out in the mouth as long as survivor fast turns on oxygen switch toward mask on headgear, even if at this moment people is submerged by water the escape action also calmly, composedly carrying out next step.

As can be seen from explanation above, in car of the present invention, life saving mask for subsequent use should comprise rubber face mask and compressed oxygen cylinder also has tracheole.

Vital point of the present invention makes people obtain oxygen fast to tackle water just fast submergence human body, might as well although obtain oxygen time a few minutes.Facts have proved: common people just cannot stand being submerged by water to hold the breath for 50 seconds afterwards, within 60 seconds, just because of brain anoxic, Bewu βtseinstrubung starts habitual respiratory movement afterwards, but inspiration is water entirely, so start to struggle, very fast shock death: if can not the person of holding one's breath or general women, be submerged in general 20 seconds and just start to enter the struggle phase, that can touch away escape in car only has a few peoples.My invention's mask has been born with regard to not dead so much people earlier.

The deflation rubber face mask of life saving mask of the present invention is connected with compressed oxygen bottle and small hose one, such design, is the simplification, rapid in order to the use as escaping tool.The face that the elasticity of rubber face mask makes face shield be close to people enters into nostril and the eye of people with waterproof.Certainly, the nose areas of face shield also has projection just to hold nose, and eye also has glass part to make people see outside.Compressed oxygen bottle on mask can not be excessive, overweight in order to avoid become the burden of head part.The weight of an oxygen bottle is generally designed to the oxygen a few minutes just can supplied between 200 grams to 400 grams needed for people's eupnea.Compressed oxygen bottle tie up be attached to head-shield rear portion or side in order to avoid affect the visual field of people.It is very tight in order to avoid pull disconnected that oxygen tubule also attaches.

Any escaping tool all should be designed to the habituation that applicable people uses.People gets used to, with respiratory nasal, so just allow oxygen tubule lead to the position, nostril of people, allowing people from nostril oxygen intake.Such design, so mouth just answers breath, and face part just need not cover.

The deflation cover mouth of life saving mask of the present invention not at neck in the ear bottom of the upper jaw of people and people.Why not at neck? neck because of people has much important blood vessel, human brain can be made numb to stupor if can oppress these blood vessels blood that can not pass through in neck deflation.Face shield does not all overlap the Another reason of perfect person head, be allow people see a people has on life saving mask, if all covered head, such monster has emerged from the water suddenly, and people has on the bank been frightened away entirely.Mouth top deflation approach makes mouth expose can breath.The nose areas of face shield should have projection to place nose, and oxygen hose also can be lead to this prominence, and entrance is just facing to nostril.If it is tight not that face shield is worn, there is water can get into nose limit, just oxygen bottle switch is twisted and a bit allow oxygen pressure compel from nostril by water greatly, at this moment enter water place and not only do not intake and get out oxygen on the contrary.But be at this moment that there is little time left, takes time to escape at waste oxygen.

What kind of does is the state of life saving mask of the present invention time for subsequent use? make because head-shield is rubber, so can one be become to encase little oxygen bottle by soft wrinkle, all also only an etui just can load, and this etui is placed in car easily stretches out one's hand the place of just taking.Etui should be carton, and Emergency time just can be ripped taking-up mask once.Rush in the moment in water at car, people need not six seconds from taking that box to turn on before and after oxygen switch to cover to head, and at this moment water is not also dipped into knee, and the flurried and fear of people is cut down most at once.Such escaping tool is used to be really too simple and quick.

The beneficial effect of life saving mask of the present invention is: when automobile is rushed in water, substantially increases people's success ratio that success is escaped in car.

Detailed description of the invention

Below in conjunction with accompanying drawing, enforcement of the present invention is further illustrated.

In Fig. 1, the hair (11) of a women people is very much long but also can put on the life saving mask of my invention.Life saving mask in figure should comprise a rubber and tighten head-shield (1) and compressed oxygen cylinder (2), also has oxygen small hose (4).First see head-shield, the eye of head-shield has clear glass part (7), people also can be opened eyes in water and see outside clearly reluctantly.The nasal portion of head-shield has protuberance just to hold nose, and protuberance bottom is oxygen insert port (6), inner just facing to the nostril of people.See in figure that head-shield (1) did not cover face (9), just covered the head of more than people's upper lip.Can't see ear in figure, is because ear has also covered.Head-shield ear bottom also has one to grasp mouth (8), is convenient to use when people wears a mask or takes off mask.See compressed oxygen bottle (2) again, only see an oxygen bottle (2) in figure, the long barrel shape of bottle, length also only has half head of people.Although it is little, inner compressed oxygen can supply people's eupnea about three minutes.One screwing type switch (3) is arranged at the top of oxygen bottle (2), just has oxygen to enter the nostril of small hose (4) to intelligent from oxygen outlet (5) as long as people twists some positions by custom clockwise direction.

In Fig. 2, we see the front portion of the life saving mask of my invention.This figure is to people's symmetrical sensation: there is clear glass part (7) at eye two place; Nostril bump pad has two small hose sockets, and oxygen hose also sees two; Also exposing the little oxygen bottle of compression (2) in figure is two.See in figure that head-shield (1) bottom is narrowed and become head-shield tightening mouth (12), head-shield tightening mouth caoutchouc elasticity from the upper lip and ear bottom of people tightens, and the hair of people from rear portion is also by deflation tighten.Whole head-shield is under the projection of the nose of people and ear hinders, and tightening mouth (12) can not carry out various action and sliding position because behaving, and this is that the whole life saving mask of my invention stably can be worn over the major reason that the head of people can not at will depart from.

In Fig. 3, we see the back side of whole life saving mask.See in figure that two little oxygen bottle of compression of a size (2) tie up the rear portion being attached to head-shield (1), the first from left, right one.Why not design larger just not saving trouble? so also passable, but make because head-shield is elastic caoutchouc, and can there is tenesmus because of certain overload in the rear portion of head-shield; The occurring side by side an of head and a large bottle also increases diameter, makes people be difficult to get out from little escaping exit.Two bottles are separately tied up attached just not same, and the Heavy Duty both having alleviated head-shield certain also balances the load sensation of head part.Do not look down upon this two ampoule (2), each opening can supply people the oxygen demand of about three minutes, if be for subsequent use with one, two priorities can supply people the oxygen demand of about six minutes, in these six minutes, even if people is submerged by water, the people be trapped in car also calmly, composedly can open car door or batter down vehicle window and get out to climb up on top of the water outside car and draw to bank again.
