Description

Breathing apparatus

The present invention separates the air supply side and the discharge side for inhalation and exhalation at the entrance of the nostrils, so that the exhalation is recovered and used, so that it is possible to breathe without inflow of external air, thereby preventing toxic gas poisoning in the fire scene with many toxic gases and oxygen deficiency. It relates to a breathing apparatus for emergency evacuation to respond to asphyxiation accidents caused by, and is used as a dust mask in normal times, but in case of entry into a closed environment or a fire, the air supply pipe of the separator is blocked, a collecting bag is installed at the breathing outlet, and the air in the collecting bag is It relates to a breathing apparatus for emergency evacuation to breathe with.

When a fire breaks out in a building, black smoke is emitted, which contains a large amount of toxic gas, and breathing stops even if you take a few sips of this gas. Failure to supply oxygen immediately leads to death. Like this, most of the fire deaths die from poisoning by this toxic gas. In addition, gas poisoning is the main cause of accidents that people who work in closed places such as oil storage tanks, wastewater treatment facilities, sewers, manholes, septic tanks, chemical plants, and shipyards with the risk of toxic gas leakage. In accordance with these circumstances, an oxygen generating respirator, which is a type of respiratory system, is published in the inventions presented in Patent Documents 1 to 2.

The above invention relates to a self-contained oxygen respirator that generates oxygen with the user's breathing air and supplies it to the user again. Calcium hydroxide reacts with carbon dioxide, and when it reaches a certain level, it is decomposed into carbon dioxide again, causing death due to carbon dioxide poisoning. . Therefore, the reacted by-products are inconvenient to use, such as the hassle of having to replace them quickly and the problem of being heavy in weight, so they are not widely used.

Moreover, the oxygen generating device cannot be separated from the respiratory tract, so there is a limitation in being widely used, and there is no space to store air when self-breathing.

If a commercially inexpensive oxygen can is directly blown out, it is not used for evacuation because the amount of use is too short to be thrown into the air, and the inventions so far have not been utilized for the purpose of solving in the invention device.

In addition, there is a nose mask (patent 10-1739568) developed to prevent fine dust in everyday life, but there is a problem that inhalation and exhalation are mixed, and a tube is inserted into the nose, so that the user feels uncomfortable and reluctant to use it.

Disposable masks, oxygen-generating respirators, and nose masks mentioned above were used respectively, but there are problems by themselves and incompatible with each other.

Rescue masks are disconnected from life and are not placed in public places or homes because they are for limited use, so it is not possible to survive when a person falls or a fire occurs.

As shown in Figure 1, the breathing apparatus according to the present invention includes a separator 100 and a filter 200, and a collecting cloth 400 that can be optionally used.
Referring to FIG. 2, the separator 100 is formed so that the breathing port 120, the connector 140, and the exhaust port 160 are communicated with each other.
The breathing port 120 is formed upward toward the nostril in the breathing apparatus body according to the present invention in which the inside is formed hollow, the connector 140 is formed on both sides of the body, and the exhaust port 160 is formed downward of the body As can be, each can be formed in a structure that protrudes to a certain length by forming a tube shape.
Breathing apparatus 120 is provided with a pair of ends are fitted to both nostrils. At this time, there is a packing installed in each of the breathing apparatuses 120, the packing being a primary packing 122 formed at a position to be inserted into the nostril and a secondary packing formed under the primary packing 122 to block the entrance of the nostril Includes 124. The primary packing 122 is made of a soft material to reduce foreign body sensation, and the secondary packing 124 is formed to improve fit while maintaining airtightness by being in close contact with the state covering the nostril entrance.
That is, the problem of reluctance to use the separator of the present invention in the nostril is that the first packing 122 is soft by inserting the packings 122 and 124 in duplicate at the end of the tube located at the nostril entrance of the breathing apparatus 120 It is made to fit a little as if covering the nostrils with a run material, and a secondary packing (124) made of urethane material is made of a second packing (124) made of urethane material where each person has a different nostril, nostril, and nose tip contour to improve the fit.
In order to improve the aesthetics of the separator 100 made in this way, and to improve the risk of injuring the nose and unsafe attachment, for example, cover the separator with a cover made of urethane, then connect it with strings 700 at both ends of the separator, and wear it on the ear or wear it on the head. If the rim-shaped legs 400 are worn at both ends of the separator, they can be safely used without feeling unsafe and aesthetically rejected.
At this time, the cover is not separately shown, but it is desirable to improve the aesthetics while protecting the nose by being integrally formed with the separator to cover the nose, the nose blades, and the nostril furrow as if it is covered in close contact and not shaken.
The opening and closing device 350 is installed at the connector 140 and the exhaust port 160. The opening/closing device 350 may be separately prepared and mounted, and adopts the check valve principle to induce the flow of air in only one direction. That is, the connector 140 guides air in the inhalation direction, so that air is introduced into the separator 100 to supply external air to the user, and the exhaust port 160 induces air in the exhalation direction, thereby separating the user's exhalation. (100) The bar is formed so as to be discharged to the outside, and thus is supplied to the inhaled connector 140 according to the user's breath, while being discharged through the exhaled exhaust port 160.

As in the embodiment illustrated in FIG. 3, a connection device 300 is coupled to the connector 120 and the exhaust port 140 of the separator 100, but the inside thereof is opened in one direction by breathing and the other is closed. An opening/closing device 350 implemented as a check valve is mounted in the center, and when the opening/closing device 350 is pulled out from the connecting device 300 and rotated in the opposite direction, air flows only to the other side than before. The basic structure is that the air purified through an inhaled filter and a filter to be described later passes through the opening and closing device 350 of the connector 140, enters the separator 100, and is placed on the two nostrils. 120) through the human body. Air entering the separator through the two tubes placed on the exhaled nostrils is blocked by the opening and closing device 350 by a connecting device inserted in the inhalation direction and exits through the exhaust port 160. This is because the exhaust port may also be provided with a connecting device provided with an opening and closing device so that inhalation is blocked and only exhaust.
An example of such a connection device 300 is, in detail, a connector fixing jaw 145 and a connector thread 147 that are fixed when inserted and rotated in the outer diameter of the connector 140 and are not removed, and the inner diameter of the connector 300 is thus By installing the corresponding connection device fixing jaw (not shown) and the connection device thread 320, it is a structure that couples them to each other. Thus, when the opening and closing device 350 at the center of the connecting device 300 is completely turned in a state in which it is coupled in the inhalation direction, the check valve is completely blocked while touching the end of the connector 140, and in case of an emergency, such contaminated poisonous gas is removed from the connector ( Through 140), it is possible to recycle and breathe by combining the collecting cloth to the exhaust port 160 as described later in a state that is blocked from entering the separator 100.

Meanwhile, the filter 200 may be functionally connected to the connector 140 of the separator 100. That is, the opening and closing device 350 may be provided directly to the connector 140 of the separator 100 or may be provided in a separate connector 300 and indirectly coupled to the connector 140, and the filter 200 is a connector. Filters the air flowing into the separator (100) in a state directly or indirectly connected to (140).
The filter 200 may be any one such as an encapsulation filter, a cylindrical filter, and a pleat filter, and may be formed in a state accommodated in the filter housing. And while the filter is provided in this way, the user can wear the breathing apparatus of the present invention by hooking the string 700 to the ear.

As an example, referring to FIG. 5, an encapsulated filter 210 is inserted into both connectors of the separator 100 (a) a string 700 is attached to the end of the filter and worn on the ear, or the filter case 220 is attached to the separator 100. After inserting the square filter 230 into the inside (b) attach a string 700 at the end of the filter case 220 and hang it on the ear to wear. Alternatively, a small filter case 260 containing a small filter such as a pleat filter 240 or a circular filter 250 may be inserted into the separator 100 (c) and a string 700 may be connected to the separator 100 to be worn on the ear.

On the other hand, the breathing apparatus of the present invention may be formed to be worn on the head using the leg 400 by having a head-shaped leg 400 connected to the separator 100 and formed to be mounted on the head.
The leg 400 is formed to have a certain length and hangs on the ear or wraps the head like glasses, and the filter house in which the filter 200 described above is mounted may be provided inside, and a light, speaker, USB terminal, earphone jack, and Bluetooth At least one of a transceiver, a GPS transceiver, and a battery may be formed. Lights, speakers, USB terminals, earphone jacks, Bluetooth transceivers, and GPS transceivers operate in dangerous situations by interlocking with various devices such as smartphones according to their unique functions, and the lights illuminate or flash the darkness to guide the way in an emergency situation. , The speaker delivers information to the user from the outside, and serves to identify the location of other users to help safe escape from the dangerous area.
This will be described in more detail with reference to FIGS. 6 and 7, the bridge 400 includes various types of bridge filters 411, 412 and 413 inside the filter housing 410 provided therein through the filter connection part 414 through the connector 140 When worn over the ears, as if wearing glasses, it is fixed with its own elasticity.
And at the back of the leg 400, a light 420, a speaker 430, a USB 440, an earphone jack 450, a computer operation card 460, a transmission/reception unit 470 capable of transmitting and receiving such as a Brutus or GPS, It is equipped with a battery (480) to notify and report when a fire breaks out, and to turn on the light and evacuate.
Specifically, it is linked to the wearer's smartphone and the Brutus, and performs the function of performing the calculations of the smartphone on the leg. It notifies detected fire or received fire information, connects with the communication function of the smartphone to make an emergency call directly, receives the drawing of the building from the building or downloads it from the disaster prevention center, calculates the escape route, and calculates the escape route from the smartphone. When it is delivered to, the light is turned on and off on the right and left, so the road is guided, and the speaker stabilizes the embarrassed wearer and explains how to evacuate.

Meanwhile, the exhaust port 160 of the breathing apparatus according to the present invention may be provided with a collecting cloth 500 formed in a bag shape to collect the user's exhaust and convert it into oxygen for reuse for breathing. The collecting fabric 500 is formed in the form of an envelope with wrinkles 510 formed as shown in FIG. 7 and can be folded when not in use, and this configuration helps to minimize the volume when not in use.

The collecting cloth 500 is provided with a collecting inlet 520 connected to the exhaust port 160 of the breathing apparatus 100 and a collecting outlet 530 connected to the connecting port 140 of the breathing apparatus 100, so that the separator ( It is connected to 100), collects the wearer's exhaust, reduces it to oxygen, stores it in the bag, and then inhales and breathes again.
At this time, before connecting the collecting cloth 500 to the separator 100, the wrinkles 510 of the collecting cloth must be increased so that clean air from outside enters as much as possible.

The collecting cloth 500 must be a size capable of containing an adult's tidal volume so that it can breathe until evacuation with only one's own breath without supplying external air at a site where there are many toxic gases. In 600ml of exhalation that a person breathes once, oxygen that can be breathed several times remains, so it is recycled and the amount of carbon dioxide is not exceeded by a certain amount to prevent carbon dioxide poisoning.

In the case of using the breathing apparatus of the present invention by connecting the head-shaped leg 400 described above, one of the connecting ports 120 of the separator 100 provided with the leg 400 is blocked to prevent external air from entering. After connecting the collecting outlet of the collecting cloth through a separate connecting pipe 490, for example, to the other connecting port, connecting the collecting inlet 520 of the collecting cloth 500 to the exhaust port 160 can be used. .

Inside the collecting fabric 500, a reaction frame 540 variously illustrated in FIG. 8 is formed. Since the reaction frame 540 contains soda lime, sodium hydroxide and soda lime are mixed and used, water is mixed with soda lime, and kneaded, and then applied to the reaction frame 540. In detail, the exhalation separator 100 passes through the collection inlet 520 and enters the reaction frame 540 of the collection cloth 500, and the reaction frame 540 is in the form of a mesh (a) or a cluster of grapes (b). Soda lime is applied to the tube in a wet state, and the carbon dioxide and moisture contained in the exhalation are collected so that the carbon dioxide is removed and oxygen is generated, and then the generated oxygen goes to the separator 100 through the collection outlet 530 It is a structure supplied to the wearer.
That is, the reaction frame 540 may be formed in a state in which the top and bottom are opened in a plastic wrap 570 in a mesh shape or a grape cluster shape, and in this case, the inlet of the plastic wrap 570 is connected to the exhaust port 160 As the exhalation passes through the inside of the plastic packaging 570, the reaction frame 540 may react with the soda lime to generate oxygen. Oxygen generated in this way is supplied to the breathing apparatus 120 again through a connection pipe 490 connected to the breathing apparatus 120 and supplied to the user when inhaling.
The reaction equation is as follows.
1) co2 + NaoH = NaoHco3

delete

2) NaHco3 + Ca(oH)2 = Caco3 + H2o + NaoH

Applying a carbon dioxide reactant to the inside of the reaction frame is a device for allowing exhalation to pass through and making the soda-lime dough, which is sticky like mud, not stick to the collecting cloth 500, so that the collecting cloth 500 can be easily opened.

When not in use, the collecting cloth 500 is blocked so that the collecting cloth 500 is sealed with, for example, a silver foil 550 or the like in order to prevent external air from contacting the inner reaction frame 540. And when in use, the silver paper 550 is removed, the blocking device on the exhaust port 160 side of the separator 100 is removed, and connected to the collecting inlet 520.

Meanwhile, in the case of an emergency, the trapping cloth of the present invention is fixed in a folded state at the entrance of the reaction frame 540 so that the mask covering the nose is fixed as shown in FIG. 9 and then pulling the perforation line 560 of the folded part to open the mask. And use it independently.

Meanwhile, when the collecting cloth 500 is first worn on the breathing apparatus of the present invention, the amount of oxygen generated when carbon dioxide is removed from the wearer's breath and oxygen is generated is small. Conversely, when used for a long time, the carbon dioxide remover in the reaction vessel is exhausted. In order to compensate, a separate oxygen can 600 may be connected by plugging it into the connector 140 through a connector 490.
That is, even if the life of the filter is over or oxygen is urgently needed, breathing is possible through the additional oxygen providing means through the connection pipe 490 shown in FIG. 6 as an example to the connector 140 of the breathing apparatus.
Thus, the present invention may further include an oxygen can 600 for supplying oxygen through the connector 140. The oxygen can 500 is connected to the connector 140 through a connector 490 to supply oxygen. It is preferable to use the oxygen can 600 in a state of being attached to the arm or neck or by hanging it. The oxygen can 600 can be installed and used in an emergency situation, but a person who lacks exercise or an examinee can use it for oxygen breathing for mood change.

Excessive inhalation of oxygen can be dangerous, but commercially available oxygen cans that are released when pressed and stopped when released are provided through a thin tube and are provided slowly, and the method of controlling the supply amount when pressed by the user is an easy-to-use method. If the connector provided by the present invention is tightened several times in front of the separator as a lane, the air is blocked, and when it is opened, it can be used while opening and shutting. It is possible to use a connector 31 for gas that allows less passage.

When oxygen is excessively supplied, it enters the trap through the exhaust port and mixes with nitrogen that continues to circulate in the bag, making it safe and easy to use. Specifically, a long, soft hose such as vinyl is connected to the oxygen can to the breathing separator.When storing, keep the bag wrapped around the oxygen can with the bag attached to the oxygen can. All of these are connected. The head frame is also set to be used in an emergency, stored with an oxygen tank, and when worn, you can hang it on your nose and hang your legs on your ears as if wearing glasses.

The oxygen can 600 is inconvenient to hold the hand in case of emergency evacuation, so it is inconvenient to hold the oxygen can in a pocket or a hanger device 610 on the oxygen can and hang it on the neck rim 620 of the clothes worn. This method is small in volume, inexpensive, and easy to equip because it uses oxygen cans in daily life.
