Description

An Emergency Mask for securing golden time

The present invention relates to a mask for securing a golden time, and more specifically, carbon dioxide is emitted from the exhaust gas discharged at the time of exhalation by configuring an oral/nasal boundary filter part separating a nasal suction part and an oral discharge part inside the body provided with a filtration filter. It relates to a mask for securing a golden time that enables reuse of the removed air and purified outside air for breathing.

Due to the urban concentration of the population, the city's population is increasing, causing various social problems.

In particular, various incidents are frequently occurring due to the increase in the number of users using the multi-use facilities or public facilities, and in particular, in the event of a fire, many users often lose valuable lives.

In the case of buildings in large cities, high-rise, high-density building and fires often lead to a big accident, and in particular, the interior of the building is closed by using a lot of light-weight and easy-to-use construction materials among various building materials. In the case of interior decoration, the flames spread rapidly during a fire, and often cause toxic gas during combustion. For those who have not evacuated, death or serious sequelae by inhaling toxic gas generated during combustion of indoor building materials It is often the case that causes the.

In order to reduce the toxic gas generated in the fire, the interior is closed by using a flame retardant material, but in the case of flame retardant construction materials, the price is high. Therefore, in case of fire, people can not recognize the fire and evacuate to a safe place without burning time (hereinafter referred to as'Golden Time'). There are cases of suffocation with toxic gas even before it is done.

Accordingly, various types of gas masks or masks have been devised to secure a minimum golden time during a fire to reduce loss of human life.

As an example of this, the Korean Air Patent Publication No. 10-2016-57109 (Publication Date: 2016.05.23) created an'air pocket' and placed it inside a subway or building or in a public place, etc. Therefore, the suffocation can be prevented from occurring.

The'air bag' is made of polyvinyl chloride and is configured to allow the user to bite the mouthpiece with the mouth and inhale it with air filled in the polyvinyl chloride for a certain period of time, but the face mask is used by the user to exhale when breathing. At the moment of being separated from the face, toxic gas from outside is forced into the inside of the face mask, so it is not practical to use in the fire scene.

In addition, as another conventional embodiment, Korean Patent Publication No. 10-2015-125905 (published date: 2015.11.10) has been devised a “fire retardation and dust mask for evacuating fires”.

The conventional'fire retardant and dust mask for evacuation of fire' is provided on the upper part of the filter part of the face part and the filter part of the face part made up of several layers of filters capable of anti-gas and braking, and configured to secure the user's field of view during operation. Consisting of a closed eyeglass, a face filter, and an elastic band connected to the face filter and a closed eyeglass to fix the eyeglass to the user's head.

These'fire retardant and dust-proof masks for evacuation of fire' have a characteristic that the sealed glasses are integrally formed on the top of the face mask, but the sealed glasses are rather difficult to wear for the wearer of glasses, and the foreign matter may get stuck in the glasses in case of fire. There was a problem in that it could act as an uncomfortable element that obscures the field of view.

On the other hand, in the case of a conventional anti-vibration, anti-gas, anti-fogging mask in use, filtration filters of various structures and materials are used to filter harmful gases to the human body as external air flows in.

However, as the performance of the mask is improved, the air permeability of the filtration filter is lowered, that is, as the harmful gas collecting ability is improved, the ventilation resistance through which the air passes is increased. If it flows through the bay, breathing quickly becomes short and breathing occurs.

Therefore, even if a mask is worn, it is very difficult to survive for a long time in a contaminated area while wearing only a mask in a state where it is not avoided as a safe area.

In other words, if the mask has excellent sealing ability and excellent dust-proof, anti-gas, and flame-retardant performance, it is in close contact with the face area and the edge of the mask, and the sealing force is excellent. , In the space inside the mask that covers the respirator, a small amount of external air that has passed through the filtration filter from the outside coexists with the exhalation that is emitted when the user breathes, and the carbon dioxide content increases rapidly inside the mask, contaminating the outside air Rather, a mask that performs a function of blocking may cause a situation in which breathing becomes more uncomfortable.

That is, the inside of the filtration filter of the mask covering the user's respiratory tract has a very high carbon dioxide concentration than expected because only a small amount of outside air flows through the filtration filter by the user's breath, and the air discharged through exhalation when breathing is mixed. State.

In general, air composed of 78% nitrogen, 21% oxygen, and 0.03% carbon dioxide is inhaled through the respiratory tract when breathed out, and 76% nitrogen, 14% oxygen, and 4% carbon dioxide are emitted from the air exhaled. It is known to contain.

Accordingly, the concentration of carbon dioxide is rapidly increased due to the exhalation generated during several breaths in the filter filter of the mask in a state in which external air is insignificant, and the mask wearer can continuously inhale carbon dioxide emitted during breathing and lead to carbon dioxide poisoning. There will be.

In general, at 3% carbon dioxide, symptoms of respiratory distress appear, at 4%, headache and tinnitus, increased blood pressure, decreased heart rate, fainting, and vomiting. In 6%, respiratory rate increases rapidly, and at 8-10%, consciousness. It is known to be unknown, with 20% of central nervous system disorders and 30% of deaths.

Therefore, in the conventional mask, when self-breathing, the carbon dioxide contained in the exhalation is forced to be inhaled again, and the air inside the filtration filter having an increased carbon dioxide concentration is repeatedly introduced into the user's respiratory system, thereby increasing the user's respiratory difficulty. In the case of exceeding the time, that is, the golden time, there was a problem that wearing a mask could be harmful to the user.

-Korean Patent Publication No. 10-2016-57109 (Publication date: 2016.05.23, title of invention: air bag) -Korean Patent Publication No. 10-2015-125905 (published date: 2015.11.10, title of invention: anti-gas and dust mask for evacuation of fire)

The present invention has been devised to solve the problems of the conventional dust-proof, anti-gas, and flame-retardant masks, and can be easily worn in the event of a fire and can increase the golden time required to evacuate to a safe area to minimize the occurrence of human injury. It is intended to provide a mask for securing golden time to enable the purpose.

Particularly, the present invention allows air supply by connecting an air bag filled with fresh air separately to the nasal suction part through which external air flows, and removes carbon dioxide from the air discharged during exhalation so that it can be reused during breathing to wear a mask. Another purpose is to provide a mask for securing golden time, which enables quick and safe evacuation by reducing feelings of tightness and reducing emotional anxiety by maintaining stable breathing.

In order to achieve the above object, the mask for securing the golden time according to the present invention is made of an elongated body and configured to be attached to the wearer's face while simultaneously covering the wearer's mouth and nose; A filtration filter provided in the central portion of the body to be purified as the harmful gas passes and flows into the body; It is used for dustproof, anti-gas, and flame retardant, including; a face adhesive portion having an adhesive layer with a release paper attached to the edge portion of the body so that the outside of the body adheres to the wearer's face portion to prevent outside air from entering the body through the adhesive portion. Provided with a mask, particularly in the inner space portion of the body where the filtration filter is provided, a nasal suction portion that allows purified air that has passed through the filtration filter to be sucked into the nasal cavity by inhalation during breathing, and into the body during breathing The oral discharge portion for discharging the air to be exhaled is configured to be divided up and down, and between the nasal suction portion and the oral discharge portion, carbon dioxide is removed from the exhaust discharged to the oral discharge portion during exhalation and then introduced into the nasal suction portion to enter the nasal suction portion. It consists of a configuration with an oral/nasal boundary filter equipped with a carbon dioxide removal function to be reusable when breathed by being mixed with purified air.

In addition, the oral discharge portion is provided with a vent valve provided with a check valve so that the air discharged from the oral cavity is directly discharged to the outside of the body during exhalation, so that a part of the exhalation is discharged outside the body and a part of carbon dioxide. After being removed, it is introduced into the nasal intake and is configured to be reused by breathing.

In addition, the oral/nasal boundary filter is attached to the wearer's face, and the adhesive layer with the release paper is formed on the edge surface so that air communication between the top and bottom is limited, and the face adhesive and the inside adhesive are provided. Each release paper is connected to the other end of the connecting member, one end of which is connected to the packaging bag containing the body so that each release paper is naturally separated from the adhesive layer when the main body is withdrawn from the packaging bag.

In addition, an airbag filled with a predetermined volume of air is connected to the nasal suction part by a supply tube for supplying air, and is made of a characteristic configuration that allows a certain amount of fresh air to flow into the nasal suction part when inhaled.

The mask for securing golden time according to the present invention described above is divided into a nasal suction part which is an inhalation space formed inside the filtration filter and an oral discharge part which is an exhalation space, and the air sucked into the human body is introduced from the outside. Breathing is reduced by reducing the feeling of tightness with insufficient amount of air that is sucked through the filtration filter by reusing the purified air and the air passing through the oral/nasal boundary filter part from the oral discharge part to recirculate the inhalation discharged when breathing. Do it.

In addition, according to the present invention, the air bag provided separately from the outside of the nasal intake is connected to the nasal intake by a connecting hose to supply a certain amount of fresh air upon inhalation.

The mask for securing a golden time according to the present invention (hereinafter abbreviated as'mask') is a simple wearability that facilitates quick wearing in an urgent situation, and a golden that can extend the golden time that can be secured by wearing a mask as much as possible. It is composed of more advantageous structures to protect valuable lives from various harmful environments through time improvement.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 to 5 relates to a mask according to an embodiment of the present invention, FIG. 1 is an external perspective view of the mask, FIG. 2 is a rear view of the mask, and FIG. 3 is a vertical view of the mask along line AA of FIG. 1 Each cut section is shown.

As shown in Figures 1 to 3, the mask 50 according to the present invention has a shape of the main body 10 is formed in a round shape from the teburi area toward the center, so that the central portion rises convexly and the overall shape is like It is made in the form.

In this way, the mask 50 according to the present invention formed in the form of a cone has a central portion of the body 10 convexly protruding and convexly protruding inside the body 10, the mask wearer's respiratory tract, that is, the nose (nasal) and The mouth (oral cavity) is configured to be located, and the nose (nasal cavity) and the mouth (oral cavity) are composed of a configuration provided with a filtration filter 20 to allow suction after the external harmful gas is purified in the center of the body.

In the center of the body in which the filtration filter 20 is located, a nasal suction part that allows the wearer of the mask to fill the purified air introduced through the filtration filter 20 with the nasal cavity of the wearer and enters the body into the body when breathing. 22) is formed on the upper portion, the nasal suction portion 22 is exhaled from the body when exhaling the oral discharge portion 24 is filled with a structure formed to be separated from each other.

That is, the oral/nasal boundary filter unit 30 is formed between the nasal suction unit 22 and the oral discharge unit 24, and the oral/nasal boundary filter unit 30 is exhausted when the mask wearer exhales. Among them, only the air in which the carbon dioxide is removed is moved to the upper nasal suction unit 22 and is mixed with the purified air introduced from the outside and made of a characteristic configuration that can be reused when the mask wearer breathes.

In addition, the rim portion of the main body 10 is adhered to the wearer's face portion, and the face adhesive portion 12 is made of a certain width, and the face adhesive portion 12 has a fixed thickness of the adhesive layer 14 and the adhesive layer. Consists of a configuration in which a release paper 13 for preventing foreign matters from sticking to the surface of (14) is attached, and after removing the release paper 13 when wearing a mask, the adhesive layer is configured to adhere to the wearer's face portion sensitively.

As described above, the nasal suction unit 22 is configured toward the upper side based on the central portion of the main body 10, and after the external harmful gas is purified while passing through the filtration filter 20 during inhalation due to the wearer's breathing, the nasal suction unit 22 ) It is configured to flow into the body through the nasal cavity when breathing through the inside of the mask wearer, and the air introduced into the body through the nasal cavity is discharged through the oral cavity through the oral cavity to the oral discharge part 24 after breathing. It is configured to be discharged to the outside through the exhalation outlet 40 provided on the lower side of the oral discharge unit 24.

Meanwhile, the oral/nasal boundary filter unit 30 provided between the nasal suction unit 22 and the oral discharge unit 24 blocks the upper nasal suction unit 22 and the lower oral discharge unit 24. Therefore, it is configured to restrict communication of cold air therein.

That is, the oral/nasal boundary filter unit 30 is made to be able to communicate only from the lower-side oral discharge unit 24 to the upper-side nasal suction unit 22, and is particularly configured to have a carbon dioxide removal function, thereby exhaling the wearer of the mask. Some of the exhaust gas is discharged to the outside of the main body 10 through the exhalation outlet 40, and some are moved to the nasal suction unit 22 in a state in which carbon dioxide is removed and can be reused when the mask wearer breathes It is configured to.

In general, it is known that the atmosphere contains 78% nitrogen, 21% oxygen, and 0.03% carbon dioxide, but when the atmosphere is discharged again through the breathing process, the exhausted air is 76% nitrogen and 14% oxygen before breathing. It can be seen that, although the content of nitrogen and oxygen in the atmospheric state is significantly lowered, carbon dioxide is significantly increased to about 4%, and is then discharged into carbon dioxide after much use of nitrogen and oxygen in the body's breathing process.

Therefore, in general, since the air discharged after breathing has a high carbon dioxide content, when wearing a conventional mask configured to simultaneously exhale and exhale in an enclosed space, the mask wearer increases the number of breaths and increases the number of respirations. The carbon dioxide content increases rapidly, and even if the outside air flows into the purified state through the filtration filter of the main body, breathing quickly becomes difficult due to the high proportion of carbon dioxide and water vapor contained in the air discharged during exhalation, making it difficult to maintain the golden time. .

However, in the mask according to the present invention, the inhaler in which the outside air is inhaled into the nasal cavity is made, and while the exhalation is performed to discharge the air used when breathing through the oral cavity, the high content of carbon dioxide contained in the exhalation is re-inhaled by the mask wearer. Instead of passing through the oral/nasal boundary filter unit 30, only the air in which the carbon dioxide is adsorbed and removed is moved to the nasal suction unit 22 and mixed with purified air introduced from the outside to be reused for breathing through the nasal cavity. When the inflow of purified air into the nasal suction part is not flowing or the inflow of purified air is not smoothly performed, the exhalation discharged by one's own breath for a certain period of time can be reused to improve the golden time. Keep it.

In addition, the exhalation outlet 40 provided on the lower side of the oral discharge unit 24 consists of a one-way check valve structure that allows air to be communicated only in the outer direction of the main body 10 and to prevent inflow from the outside of the main body to the inside. It is configured to prevent harmful gases from entering through the exhalation outlet 40.

The exhalation outlet 40 according to an embodiment shown in the drawing blocks the inflow of polluted air or harmful gas from the outside to the inner tip made of an empty cylindrical shape while inhaling it to purify it when harmful gas is introduced Prevention filter 44 is provided, the upper side of the intake prevention filter 44 is made of a conical shape to facilitate the discharge of the exhalation is made of a configuration provided with a check valve 42 toward the outside.

In addition, the outer rim surface of the oral/nasal boundary filter unit 30 is provided with a fold adhesive portion 32 that is attached to the wearer's throat, similar to the face adhesive portion 12 provided on the rim surface of the body 10, and the traction The adhesive portion 32 is made of a configuration provided with a release layer 34 attached to the surface of the adhesive layer 34, and the adhesive layer 34 of a certain thickness, and after removing the release sheet 34, it is adhered to the wearer of the wearer and the nasal suction portion It is configured to be surely blocked between the 22 and the oral discharge section 24 so that the air of the oral discharge section 24 can be introduced into the nasal suction section 22 only through the oral/nasal boundary filter section 30. do.

On the other hand, the filtration filter 20 provided in the central portion of the main body 10 is a multi-layered structure in which a plurality of filter media are stacked and configured to purify various toxic gases generated in the event of a fire, and inside the main body 10 The oral/nasal boundary filter unit 30 provided between the nasal suction unit 22 and the oral discharge unit 24 is composed of a filter exclusively for carbon dioxide adsorption removal capable of adsorbing only carbon dioxide from the air discharged during exhalation. desirable.

In the case of the filtration filter 20, a primary filtration filter to filter out volatile organic compounds (VOC) and ultra-fine dust, and an activated carbon filter to filter out unfiltered harmful gases in the air passing through the primary filtration filter, or It is composed of a secondary filtration filter using activated carbon filters, etc., on which catalysts are deposited, and is configured to allow adsorption or decomposition of harmful gases, and the oral/nasal boundary filter unit 30 may be configured to enable carbon dioxide adsorption through an activated carbon filter. have.

And, Figure 4 shows a withdrawal state to withdraw the mask 50 according to an embodiment of the present invention from the packaging bag 60.
