Description

Mask for preventing inhalation of harmful materials

The present invention relates to a mask for preventing inhalation of harmful substances, which prevents inhalation of harmful substances such as viruses, bacteria, and fine dust and provides a special breathing environment for ingesting clean air.

And it relates to a mask for preventing inhalation of harmful substances, which provides sufficient air according to the activity, minimizes inhalation of carbon dioxide generated during exhalation, and includes a filter unit including porous antibacterial copper to remove viruses and bacteria.

Modern people's health is threatened by harmful substances such as viruses and fine dust. At least one proper protective equipment is essential to maintain health from these harmful substances. In particular, the mask plays the most important role in promoting safety from harmful substances.

The general mask is made of materials such as cotton, and due to the nature of the flat cotton fabric with coarse tissue, it is not effective in blocking harmful substances that are very small in size, such as viruses, bacteria, and fine dust, which are smaller than the pores formed between the tissues of the cotton fabric. there was

Recently, the demand for health masks with improved filtering performance by mixing non-woven fabrics and filters to block fine dust with a diameter of less than 10 μm and ultra-fine dust with a diameter of less than 2.5 μm, bacteria, and viruses is rapidly increasing.

However, one of the problems with the conventional mask is that the mask is worn over the nose and mouth, and since it accommodates the user's nose and mouth at the same time, the storage capacity inside the mask is large (see FIG. 13). It collects in the storage space inside the mask, and when inhaled, carbon dioxide is inhaled again, which increases the concentration of carbon dioxide in the blood and alveoli, causing a headache.

And it has been found that the material used for the mask is made of very fine mesh, making it difficult to breathe and reducing oxygen intake. It also decreases the tidal volume, increasing the respiratory rate and reducing ventilation in the lungs. In addition, there is a problem that bacteria multiply inside the mask and invade the respiratory tract.

The Ministry of Food and Drug Safety of the Republic of Korea grants KF80 and KF94 health mask certification marks when certain approval standards are passed. However, the current health mask permit standards do not consider age-specific lung capacity, carbon dioxide intake, carbon dioxide emissions, and oxygen intake.

For this reason, the World Health Organization (WHO) and the American Thoracic Society have stated in their guidelines for protective masks that “wearing a medical mask can make breathing difficult and put strain on the lungs and heart.” In addition, the US Food and Drug Administration (FDA) said, “If you have chronic respiratory, heart disease or other medical problems, you should be wary of wearing a medical mask. This is because a medical mask can make breathing more difficult for the wearer.”

In 2015, the National University Hospital of Singapore tested an N95 (U.S. standard) mask equivalent to the KF94 health mask on 20 pregnant women from 27 to 32 weeks of pregnancy. , reported a 17.7% reduction in carbon dioxide emissions.

According to the 2019 research report “Analysis of the health damage reduction effect of fine dust masks and preparation of future plans” commissioned by the Ministry of Environment of the Republic of Korea in 2019, 41 healthy adult men and women in their 20s and 30s were divided into those who wore masks and those that did not. As a result of a 17-day experiment at an average concentration of 24㎍/㎥ to 48㎍/㎥, it did not produce a significant result in blocking fine dust. In children, oxygen intake decreased by 10.6% and ventilation per minute decreased by 8%.

This means that when you breathe, the mask can negatively affect your health by interfering with the process of sucking in air from the outside into your lungs and expelling it out of your lungs.

Another problem is that since the shape of a person's face is different, harmful substances are introduced into the gaps between the mouth and nose because they do not fit the shape of the face, and the blocking rate of harmful substances is greatly reduced during physical activity. As a result of a study on 'Ambient Environment-Related Risk Assessment' conducted by the expert committee of the French Food, Environment, Sanitation and Labor Agency (ANSES), it was found that the mask's blocking rate of harmful substances was very effective in the laboratory, but not in actual use conditions.

Even if the blocking rate of the mask that blocks harmful substances in the laboratory is 95~99%, when used in the actual external environment, the effectiveness decreases to the 60% or even 0%, so there is no effect of blocking harmful substances in real life.

Another problem is that using existing masks can cause discomfort due to skin problems. If the existing mask is worn for a long time, there is a problem that the moisture generated in the mask and the increase in skin temperature increase the secretion of sebum, causing skin troubles.

Another problem is that it causes environmental pollution. Most of the health masks have a problem in that the filter performance is lowered during washing, and because of this, their use is limited and they have to be discarded every time after one use, so there is a problem in that the amount of waste is increased and environmental pollution is caused. .

On the other hand, various nanostructure-based Embrain filters have recently been developed to achieve air permeability and removal efficiency of harmful substances such as fine dust and viruses. Nanostructure-based materials including nanoparticles, nanowires, etc. have a much larger surface area than conventional commercially available textile fiber materials.

The present invention was made to solve the above problems of the prior art, and provides a mask for preventing inhalation of harmful substances that not only blocks inhalation of harmful substances such as viruses and fine dust, but also provides a special breathing environment so that breathing is comfortable and clean air is ingested. will provide

Humans breathe through the nose and mouth. However, breathing through the mouth can cause many health problems. In the case of oral breathing, the level of oxygen saturation is lower than that of nasal breathing, and the lowered oxygen saturation may lower immunity and increase blood pressure and heart rate. Mouth breathing has also been identified as a cause of respiratory diseases. It is known that 90% of people with chronic respiratory diseases are breathing through the mouth without knowing it, because there is no filtering device such as nose hairs and cilia when breathing in the mouth, making them vulnerable to bacterial infection, asthma, rhinitis, etc. It can cause snoring and sleep apnea and lead to shallow sleep, and the resulting imbalance of growth hormone can slow growth and growth, and lead to poor concentration and poor learning. In the case of growing children, due to habituated oral respiration, the pharyngeal part is lengthened, the chin is narrowed, and the lower jaw is tilted backwards.

While continuing the study, the present inventor forms the nose cover 130, which is a dedicated space for the nose for nasal breathing, and additionally configures the mouth cover portion 300 to cover the exposed mouth, so breathing is very comfortable, and occurs when exhaling A mask 10 for preventing inhalation of harmful substances that can minimize the inhalation of carbon dioxide, is very comfortable to wear, and gives aesthetic beauty was invented.

[1.1] Left and right contact parts

Hereinafter, it will be described with reference to the accompanying drawings. 1 is a perspective view showing a mask according to an embodiment of the present invention. 2 to 4 are diagrams for explaining a mask according to an embodiment of the present invention.

The mask 10 according to a preferred embodiment of the present invention is configured to include the left and right contact portions 120 .

Here, the left and right contact parts 120 are made of various materials such as silicone, elastomer, polyethylene (PE), natural rubber, synthetic rubber, etc. Preferably, there is no side effect on the skin, excellent elasticity, and the face While in close contact with the skin to prevent the inflow of external air, it is most preferable to be made of silicone, which is formed to maintain its function when worn on the human body due to its characteristics.

Here, the left and right contact parts 120 include left and right contact surfaces 123, left and right upper/lower contour parts 121 and 122, nose protrusion groove 113, chin support part 114, mouth protrusion groove 116, It is configured to include a lip support portion (119).

According to the present invention, the left and right contact parts 120 are symmetrical from top to bottom with respect to the nose protrusion groove 113 , the mouth protrusion groove 116 , and the chin support part 114 located in the center. In this embodiment, the left side and the right side have exactly the same shape. And, the left and right contact parts 120 have skin conformability, give a soft touch, and provide an inner surface and an outer surface that are non-irritating to the user's facial skin and have no side effects.

In addition, it is preferable that the left and right contact portions 120 are formed to have different double or multiple thicknesses. The reason why it is configured in such a different thickness is to allow different functions according to the thickness. That is, the left and right contact parts 120 include the left and right contact surfaces 123 formed in a thin thickness, and the lip support part 119, left and right upper/lower contour parts 121 and 122, and a chin support part, which are formed to be somewhat thick on the contrary. (114) is included. By doing so, there is an advantage in that the wearing comfort is improved and the elasticity is different according to the thickness, and there is no needless damage when the mask 10 is worn.

According to the present invention, the left and right contact surfaces 123 preferably have gas permeability as well as ultraviolet, wind, and liquid impermeability. And it is preferable to have an average thickness of preferably relatively thin, preferably less than 5 mm, more preferably 0.1 mm to 3 mm, except for certain parts. In this way, air circulation to the skin, that is, air permeability can be obtained, and there is also no possibility of unnecessarily impeding skin respiration.

According to the present invention, the left and right upper contour portions 121 have one end constituting the nose protrusion groove 113 and the other end integrally connected to the left and right band members 140, and are arranged higher and higher as they move from one end to the other. .

The upper contour portion 121 of this configuration is sealed to the skin just below the eyes in a manner similar to the wire of a bra so as not to cover the user's eyes and supports the skin directly under the user's eyes in an upward direction. , placed in close contact with the skin along the left and right temples. In doing so, since the upper contour portion 121 is in close contact with the facial skin, there is an advantage in that a gap is not generated and the outside air is prevented from permeating.

The left and right lower contour portions 122 according to the present invention have one end connected integrally with the chin rest 114, and the other end integrally connected with the left and right band members 140, and are formed increasingly higher as they move from one end to the other. and placed

When a pulling force is applied to the left and right lower contour portions 122 of this configuration, the user's left and right mandibles are entirely covered and maintained in a closely arranged state. This will support the mandible and pull it upwards, preventing the natural opening of the mouth.

In addition, since the left and right mandibles of the user are kept in close contact as a whole, the lower contour portion 122 is in close contact with the skin of the face, so that a gap is not formed, thereby preventing the penetration of external air.

Here, in particular, the left and right upper/lower contour portions 121 and 122 are preferably formed to be slightly thicker than the left and right contact surfaces 123 in order to preserve or prevent damage to the left and right contact surfaces 123 . In addition, the left and right contour portions 121 and 122 may be manufactured with the same thickness or different thicknesses in order to be in close contact with the facial skin, and may be variously changed without being limited thereto.

2 to 4, the left and right contact parts 120 have a nose protrusion groove 113, a mouth protrusion groove 116, and a chin support part 114 in order so that they are aligned from top to bottom in the center of the front surface. Consists of. The nose protrusion groove 113 and the mouth protrusion groove 116 apply pulling pressure to the front surface of the left and right contact parts 120 when the mask 10 is worn, so that the nose and mouth do not receive pulling pressure, Alternatively, the nose and mouth are configured not to contact the left and right contact parts 120 . A pulling adhesive force is applied to the left and right contact parts 120 except for the nose protrusion groove 113 and the mouth protrusion groove 116 , so there is an advantage in that it is possible to obtain an effect of blocking the inflow of external air.

According to the present invention, a lip support part 119 is additionally configured on one side of the mouth protrusion groove 116 .

The lip support part 119 is formed in such a way as to support the lips in order to prevent the lips from opening involuntarily during daily life. This configuration has the advantage of preventing fine dust, pollutants, etc. from penetrating into the body through the mouth.

According to the present invention, the chin support unit 114 is configured to naturally support the user's front jaw. For this reason, it may be formed in a concave shape such that the user's mandible front jaw is drawn in.

As the chin support part 114 is configured in this way, the chin support part 114 performs a fixing role in response to the pulling force and at the same time performs a "chin support" role for supporting the mandible. This structure is achieved by inserting and fixing the user's mandible front chin to the chin support part 114 so that the mask 10 is not excessively deflected upward. Then, it has the effect of preventing the mouth from opening involuntarily by relaxing the oral muscles and supporting the mandibular front jaw that sags downward by gravity during daily life.

[1.2] Left and right band members

According to the present invention, the mask 10 for preventing inhalation of harmful substances includes left and right band members 140 integrally formed with the left and right contact parts 120 . The left and right band members 140 are configured in the form of one left and right straps to easily and stably wear the mask 10 on the face.

Here, the left and right band members 140 may be made of various materials such as silicone, elastomer, polyethylene (pe), natural rubber, synthetic rubber, and the like.

According to the present invention, the left and right band members 140 have a configuration that is fixed by a fastening member on the user's head.

Preferably, although the left and right band members 140 are not clearly defined, one end is formed integrally with the left and right contact parts 120 in the form of a long strap having a predetermined width and length, and the free end 140a is the user's It can be fixed on the user's head by a fastening member such as Velcro or a buckle according to the size of the head.

In addition, it is preferable that the free end 140a of the left and right band members 140 is further provided with a joint adjustment member such as a buckle or a slip so that the length can be adjusted.

In addition, it is preferable that the left and right band members 140 are configured to be in close contact with the user's hair on the inner surface to prevent the user's head from flowing down.

In addition, the left and right band members 140 may be configured to further include at least one detachable hole 142 so that the mouth cover part 300 can be detachably coupled thereto.

In addition, the left and right band members 140 may be worn over the user's ear, and may be configured to be worn around the head using only the left and right band members.

In addition, it is preferable that the left and right band members 140 have excellent elasticity to be worn around the user's head, and have a width of 2mm to 50mm in order to improve the fit and prevent the user's hair from flowing down due to surface contact with the user's hair.

According to the present invention, when the mask 10 is worn, as shown in FIG. 4 , the left and right band members 140 are disposed in the upper temporal region of the user's ear.

The structural configuration of the left and right band members 140 and the wearing arrangement when wearing the mask have the effect of being worn simply and stably.

That is, when the user wears the mask 10 of the present invention, since the left and right band members are stably arranged in the upper temporal region of the user's ear, the cover part is closely attached to the skin around the user's nose. This prevents the inflow of harmful substances from the outside into the internal gas space, so that the user has the effect of ingesting the fresh air filtered through the filter.

[1.3] Nose cover

In the present invention, the mask 10 for preventing inhalation of harmful substances includes a nose cover part 130 that is integrally configured with a nose protrusion groove 113 .

The nose cover 130 is configured to include a cover body 135, an airtight cushion 132, a nose / mouth separation wall 133, an interstitial sealing portion 131 and a filter portion 139, and is opaque or transparent. , may be formed to be translucent.

The main purpose of the nose cover part 130 is to make it small so that only the nose is placed, and the cover part body 135, the sealing cushion 132, the nose/mouth separation wall 133, the interstitial sealing part 131 and the filter The unit 139 cooperates with each other to substantially partition and divide between the nose protrusion groove 113 and the mouth protrusion groove 116 to secure the ultimate internal gas space 134 that is thoroughly isolated from the external environment. will be.

According to the present invention, the cover body 135 may be formed as small as the size of the user's nose, and may be formed in a cup shape that protrudes forward in a three-dimensional shape. The cover body 135 may have a shape in which a side surface as a whole has a predetermined curvature. Through this, the wearer's nose protruding through the nose protrusion groove 113 and the inner surface of the nose cover part 130 are worn substantially spaced apart from each other by a predetermined distance, so the user's nose rubs against the inner surface of the nose cover part 130 , which is annoying. this disappears

In addition, the space in which the carbon dioxide generated during exhalation of the user stays is reduced, so that the problem of reabsorbing carbon dioxide disappears.

That is, one of the conventional problems of the conventional mask is that the mask is worn over the nose and mouth, so that the user's nose and mouth are accommodated at the same time, so the internal storage capacity of the mask is large. Accordingly, carbon dioxide generated during exhalation is collected in the storage space inside the mask, and there is a problem that the user inhales carbon dioxide again during inhalation.

In addition, it prevents skin troubles caused by moisture generated in the mask and increased skin temperature.

In addition, the cover body 135 is, in order to maintain the approximate shape of the nose cover, or to support the additionally configured filter unit 139 and various devices, the left and right contact surfaces 123 ), it is preferable to be formed somewhat thicker and more rigid.

In addition, the cover body 135 may further include coupling groove(s) (not shown). In the coupling groove, a filter unit 139, an oxygen supply device, an air circulation device, a biosignal measuring device, a humidifier, a fragrance generator, etc. may be coupled, and these devices may be configured to be easily attached and detached.

4 is a diagram schematically illustrating a correspondence relationship between a nose and a wearing position of a nose cover part according to the present invention among face parts.

Referring to FIG. 4 , when the mask 10 is worn, the eyebrow sealing part 131 is worn over the eyebrows (between both eyebrows) between the user's eyes, and cooperates with the left and right upper contour parts 121 while cooperating with each other. It is configured to prevent outside air from entering the internal gas space (134).

At this time, the interbrow sealing part 131 is formed in an approximately “⌒” shape to be in close contact with the forehead, the central part 131b is high, and the edge part 131c is relatively lower than the central part 131b. can

In addition, in order to prevent discomfort of wearing between the eyebrows and to closely adhere to the eyebrows, the upper part of the interbrow sealing part 131 may be lifted to fit the shape of the user's eyebrows and formed in an approximately “ )” shape.

In addition, the interbrow sealing part 131 may be configured to further include a nose clip 136 so as to be more closely adhered from between the pupil spaces to the brows.

Such a nose clip 136 is built into or outside the interbrow sealing unit 131, so that the user can adjust the spacing of the interlabial closing unit 131 from between the user's pupils to the user's preference. It will ensure that it can be made into a shape that is maintained at a wearing interval. Accordingly, the user can form an arbitrary appropriate wearing interval according to an appropriate situation.

5 to 8 are views specifically explaining the nose cover according to the present invention.

According to the present invention, the sealing cushion 132 is integrally formed with the nose/mouth separating wall 133 to be sealed while closely adhering to the user's pharynx on the lower part of the nose/mouth separating wall 133 . The sealing cushion 132 is configured to ensure that when an external force is applied, it is deformed according to the user's seal and sealed. Therefore, anatomically, since the central portion of the pharynx protrudes, the sealing cushion 132 preferably has a high central portion 132b, and the left and right edge portions 132c are formed in an approximately “⌒” shape to be relatively lower than the central portion 132b. do.

And, as shown in Figure 5, the sealing cushion 132 is preferably formed in a length (B) of 20mm to 70mm. More preferably, it is preferably formed in a range of 30 mm to 50 mm. In addition, it is preferable that the width is formed in a range of 1 mm to 40 mm. More preferably, it is preferably formed of 5 mm to 15 mm. In this configuration, when the mask 10 is worn, anatomically, the length of the human pharynx is 70 mm, and the distance between the nose and the upper lip does not exceed 50 mm. The sealing cushion 132 has the advantage of blocking the intrusion of external air from the pharyngeal region because it can seal the surface contact of the user's pharynx. In addition, there is an effect of preventing wear pain and wear marks by preventing line contact with the user's pharynx.

The thickness of the sealing cushion 132 is preferably formed to be slightly thinner than the thickness of the cover body 135, the folds 138, and the mouth/nose separating wall 133, and is preferably formed to be about 0.1 mm to 2 mm. .

On the other hand, the nose cover part 130 may be additionally configured with an oxygen supply device, an air circulation device, a biosignal measuring device, a humidifier, a fragrance generator, etc. on one side.

According to the present invention, the nose/mouth separation wall 133 is configured to separate the nose and mouth by a partition function when the mask 10 is worn.
