Description

Mask comprising side anchor part

The present invention relates to a mask comprising a side fixture. Specifically, unlike the conventional mask, it is not fixed to the ear and is in close contact with a specific part of the face, thereby fixing the mask to the face. It's about the mask.

Masks have been of limited use as disease-related products. It was used as an auxiliary means to prevent spread of one's disease to others or to prevent infection from others. Although the number of people wearing masks has increased due to the effects of yellow dust and fine dust, this is also to prevent diseases.

The pandemic of COVID-19 (Coronavirus Infectious Disease-19) has drastically changed the perception of masks. Masks were treated so preciously that there was a shortage of masks, and it was socially learned that masks alone are effective in preventing disease. The experience of wearing a mask most of the day was also widely shared. The negative view of covering the face by wearing a mask was also alleviated regardless of East and West.

On the other hand, in the case of a disease spread by droplets, it is desirable not to touch the mask with your hands after wearing the mask. This is because the mask may already have saliva on it, and the surface of the mask may be contaminated with other foreign substances. Medical workers are wearing masks and face shields to fundamentally block these problems. Non-Patent Document 1 is a thesis dealing with the effect of wearing a mask and a face shield as described above, and shows that the effect of the face shield is excellent.

The face shield also has a primary blocking effect against foreign substances approaching the user's face, but when worn additionally on the mask, it is very cumbersome and causes the change of the position of the mask and the change of the position of the face shield.

In the future, masks have been established as necessities like glasses. It seems that all households always stock more than the minimum quantity. It will be very natural to wear a mask even in the case of pollen in spring, yellow dust, car fumes in midsummer, and a mild cold in winter. Just as wearing glasses is not at all strange, wearing a mask will also become a very natural culture.

As the temporal, spatial, and cultural environment for masks has changed rapidly, a new concept mask that transcends the current concept is needed. As it is not only worn all the time, but also worn for a long time, a new concept mask is needed that can increase durability and reduce discomfort while increasing wearability.

The method of fixing the mask and the method of wearing it needs to be improved. The mask consists of a fixing part that fastens the mask to the face by hanging a string around the ear, and a body part that covers the nose and mouth while pressing. If the mask is worn for a long time, press marks may occur on the face and ears along the periphery of the string, which is the fixing part.

The process of wearing a mask is also cumbersome. In addition to adjusting the length of the strap, it is necessary to adjust the strength and direction of the nose compression part and the chin area according to the face. Nevertheless, the problem of fogging on glasses due to imperfect sealing is recognized as a chronic problem that is unlikely to be solved forever with current masks.

The stress on the ears must also be resolved. The mask uses the ear as the most important fixing part. Devices worn on the face using the ears as support are also on the rise. Traditional glasses, as well as headphones and earphones, use the ears as support in various ways. VR devices are also increasingly being used as products that use the ears as support.

The time spent wearing devices that use the ears as support is also increasing significantly. Glasses, which are worn all day, as well as masks, are worn regardless of place and time. It has become so natural to spend hours on earphones with the new technology.

As such, it is expected that the physical stress on the ear will increase significantly. The discomfort will be exacerbated by spectacle wearers, who account for more than 50% of adults. The daily use of masks due to COVID-19 and fine dust is also one of the factors that aggravate the physical burden on the ears.

Therefore, there is a need to develop a new method that can fix the mask to the face while reducing the physical stress on the ears. It is necessary to develop a method that can be fixed by a second seat that can assist or replace the ear, rather than the traditional method that only depends on the ear.

In order to solve this problem, the inventor of the present invention analyzed the problem of the mask. For this purpose, a preliminary study was conducted on the leakage rate according to the length of the mask string and the pain felt when wearing the mask. In the present invention, a KF94 mask was used as a preliminary study, and the study was conducted with 9 participants.

First, a study was conducted on an appropriate length of string to achieve the basic purpose of the mask, which is a low leakage rate. When the mask string length of the mask was not adjusted using a mask made for adults, the leakage rate was compared when the length including the mask string was adjusted to 120% of the face length. In the latter case, compared to the former, the leakage rate was reduced from 25% to 83%. That is, the mask can reduce the leakage rate only by adjusting the length of the string, and it can be seen that the original purpose of wearing the mask can be achieved through this.

The face length referred to here is the length of the face measured using Morpheus, and refers to the distance from the user's left ear to the bottom of the nose and from the bottom of the nose to the right ear.

If the length of the mask string is reduced, the leakage rate can be lowered, but pain in various areas was observed due to long-time wearing.

1 is a schematic diagram showing a position at which pain is observed according to wearing a mask. Qualitative evaluation was performed on the degree of pain for a specific part of the face shown in FIG. 1 immediately after wearing and after wearing continuously for 8 hours. It was observed that when the mask was worn continuously for 8 hours without adjusting the length of the strap, the degree of pain increased significantly only in the 6th area (behind the ear). Even if the degree of pressure on the face is weak, it is analyzed as pain caused by the string of the mask being continuously fixed to the ear.

When the mask strap length was adjusted to 120% of the face length and the leakage rate was lowered and worn continuously for 8 hours, pain increased in various areas including the 6th area. It was found that the pain significantly increased in the 3rd and 7th areas, including the 4th area related to the ear. The 3rd and 7th regions are the regions where the pain of the myofascial tenderness point is expressed, and it is easy to induce headache. It can cause shoulder pain.

The inventor of the present invention can confirm that wearing a mask for a long period of time can cause pain in other musculoskeletal systems other than the ear through the prior study as described above. Various pains caused by wearing a mask can also impair concentration and interfere with schoolwork or work. Recently, when wearing a mask for a long time, the problem of ear deformation in growing children and adolescents is also emerging.

The present invention is intended to solve this problem, and the present invention was derived through the process of developing a mask that can be fixed by a second seating area excluding the ear.

Patent Document 1 relates to a mask that is easy to wear, comprising a mounting portion that spans the curved portion of the front of the face, and an elastic adhesion portion extending from the mounting portion to contact the upper cheekbones and extending along the face contour to the side of the face near the ear A frame and a mounting hole into which the frame is detachably inserted are provided, the body is made of a fiber band material having elasticity, and is detachably mounted on the inner surface of the main body, which wraps around the nose and mouth of the face. The frame is provided with a mounting hole that is detachably inserted therein, and is composed of a filter covering the nostrils and the mouth. It's about keeping. The purpose of Patent Document 1 is to have a structure in which the user's face is stably attached to the user's face without discomfort to the ears, and the main body and the filter are detachable, so that the filter can be replaced, and the main body or filter can be used independently by separating the filter according to the environment of use. It is to provide a mask that can do this.

A frame extending from the mounting portion of Patent Document 1, contacting the upper end of the cheekbones, and including an elastic adhesion portion extending along the face contour to the side of the face near the ear is widely disposed in the region including the vicinity of the cheek. In this case, the weak skin is continuously stimulated, and when worn for a long time, the user not only leaves a mark on the face but also feels discomfort. In addition, it is difficult to guarantee a consistent fixing force because it does not provide a clear standard for the pressurized surface and the pressure to press it.

Patent Document 2 relates to a neck warmer for blocking fine dust, comprising: a neck cover part formed in a cylindrical shape to cover the face from under the eyes to the neck when worn; a sealing cover part formed to be spaced apart from the user's nose and mouth when worn and covered; a pressing ring portion formed on the edge of the upper end of the neck cover portion so that the upper end of the neck cover portion is in close contact with the face; And it relates to a neck warmer that includes a filtering unit that filters air by the nose and mouth, and blocks fine dust flowing into the respiratory tract as well as protecting the face and neck. The purpose of Patent Document 2 is to effectively block fine dust, but to protect the neck and face, to have adhesion to the curved surface of the face to secure the effectiveness of blocking fine dust, and to not run down under the chin during activities We present a functional neck warmer that prevents this from happening.

A typical problem of the method using the rubber band of Patent Document 2 is that 1) detachment and attachment are very inconvenient. In addition, there is a risk of makeup being removed by rubbing of the face during the attachment and detachment process. 3) When worn for a long time, the user not only leaves a mark on the face but also feels uncomfortable.

Patent Document 3 relates to a wearable mask, comprising: a body that covers and protects a mouth part of a user's face; and a face fixing member connected to the main body and contacting a part of the user's face to be in close contact with the corresponding part when the user wears the wearable mask. The purpose of Patent Document 3 is that when worn on the face, it is closely attached to a part of the face through the concave groove. It is to provide a wearable mask that can be used semi-permanently by replacing only the body.

In the case of Patent Document 3, 1) there is a risk of leaving a mark on the face due to continuous wearing, and it is difficult to guarantee a consistent fixation force because there is no clear standard for the pressurized surface and the pressure to press it.

Patent Document 4 is a system that corresponds to a three-dimensional structure based on the elasticity rate of the material used for the mask, the length from the jaw to the trajectory, the position of the cheekbones, etc. It is related to the face mask which just fits each part of the back. An object of Patent Document 4 is to provide a drawing method corresponding to the three-dimensional form of a sheet-type face mask suitable for cosmetic purposes or medical products that fit the face, chin, and frontal region and replace bandages, bandages, and eye patches, and the mask.

Patent Document 4 corresponds to extremely increasing the stress on the ear mentioned in the present invention as using the tension of the ear hooked.

Patent Document 5 relates to a mask cover that allows the mask to be mounted on the face without ear straps. An object of Patent Document 5 is to provide a mask that can be deformed according to the curved surface of the face using a material having excellent elasticity and has good air permeability of the mask cover.

In Patent Document 5, 1) a separate anchor member must be attached to the face, which may make it uncomfortable to wear, and 2) depending on the surface to which the anchor is attached, there is a risk of damage to the skin by leaving a mark on the face or by continuous stimulation. there is 3) In addition, it is difficult to guarantee a consistent fixation force because it does not provide a clear standard for the surface to which the anchor is attached.

Patent Document 6 relates to a body relaxation prevention and improvement device, which aims to reduce manufacturing cost, enables mounting on the head and other parts, and provides a body relaxation prevention and improvement device capable of applying a tensile force in the plane direction in a wide range Provided is a relief port, wherein the relaxation prevention and relief port is formed integrally with a branching part that can wind the occipital part at the base covering the area covering the tip of the chin and the lower part of the chin from the parietal region or the frontal part via the parotid muscle.

Patent Document 6 is for using the tensile force that wraps around the entire face, and it is not a means for solving the problems presented by the present invention, since it is characterized by the tensile force itself.

On the other hand, the problem of not being accurately attached to the face and lifting is a problem commonly found in goggles, gas masks, VR headsets, including masks. The peripheral part including the nose is more curved than other parts of the face, the skin is thin, so there is little buffering action, and it is difficult to accurately adhere to the face because of the high height. It is also an area that leaks more easily as the facial muscles move when breathing or talking.

In order to solve the above problem, a deformable elastic body is inserted or attached to the surface of the mask, including the nose, but it is still not in close contact with the face. Even if the metal such as wire used in most masks is deformed and the mask is in close contact with the face for a while, there is no part to support it, so there is a gap again as the facial muscles move. This problem is very simple, and it seems that it has already been solved, but in reality, it remains an unfinished state that has not been solved for a long time.

Movement of the facial muscles due to conversation or the like brings about movement of the mask. When it is necessary to wear a mask for a long time like COVID-19, skin damage occurs due to friction between the bridge of the nose and the mask. Medical staff such as nurses attach bandages or bandages to the bridge of the nose and wear masks over them to prevent skin damage caused by frequent friction.

As for the gas mask, an elastic sealing part such as silicone presses the surrounding area including the nose through a band mounted on the back of the head to increase adhesion with the face. In this case, the force to press the surrounding area including the nose is relatively large, making it difficult to operate for a long time. In addition, the problem that women avoid by leaving marks on their faces is a task that needs to be addressed.

Masks and gas masks are devices that block the flow of air, but VR headsets require airflow and light blocking at the same time. When wearing a VR headset, if the surrounding areas including the nose are not sealed, there is a problem of reduced concentration due to light exposure. All of the currently released products do not seriously consider these problems and present an unfinished technology that presses strongly like a gas mask as a solution.

Patent Document 7 relates to an inexpensive mask for the purpose of not leaking the respiratory tract, selecting an optimal pore filter portion, relieving suffocation, and providing a function to prevent spillage of glasses. It is composed of a fixing frame part with good adhesion to the skin contact part, a filter part that can be separated and attached freely, and a mounting part for fixing to the face. Each part is made of a different material and functions are shared. A notch is placed in the skin-contacting part of the fixing frame to enlarge the contact area by the tension of the mounting part, and a shape-memory resin or skin-adhesive resin that contracts with the temperature of the skin is used as a material. For the upper part of the contact part, an elastic resin that expands and contracts in response to facial muscle and skeletal deformations in conversations and changes in facial expressions is used. The filter part can be separated from the fixing frame part, and a mask is provided in which the necessary material can be selected according to the purpose.

Patent Document 8 relates to a mask including a part that closes the nose, and provides a mask having an improved nose sealing part that covers at least one of a user's nose and mouth because breathing gas is supplied under positive pressure, and the first paddle and a second paddle.

Patent Document 9 relates to a mask with a nose pad attached, and is composed of a mask body, a nose pad, and an inner layer wrinkle, the mask body has an outer layer surface, an intermediate layer surface, and an inner layer surface, the nose pad is disposed on the outer layer surface, the inner layer A mask is provided in which the pleats extend from the inner layer surface and are formed by folding, the inner layer pleats and the outer layer surface simultaneously covering the nose pad and protrusions corresponding to the nose pad formed on the mask body.

Patent Document 10 relates to a close-fitting mask provided with an elastic band, and constitutes a second close-fitting part having elasticity and flexibility along the edge of the mask body, and wraps the user's nose from above on the inner upper part of the mask body for close contact A nose pad is provided, and a lower side membrane is provided in the form of a closed curve downward from both sides of the nose pad to wrap around the nose and mouth, and the lower side membrane edge is made of an elastic and stretchable material for close contact with the skin. It is characterized in that the adhesion part is constituted and a separate elastic band having elasticity is provided at the upper position as one side of the secondary adhesion part to increase the adhesion force of the nose pad 40 to the bridge of the nose to prevent upward leakage of internal air. .

Patent Document 11 relates to a mask, and the center of the cover is provided with a receiving groove to be accommodated while the nose bridge is inserted, and the space formed between the nose bridge and both cheekbones under the eyes of the face on both sides of the receiving groove is inserted into the skin It provides a mask provided with a sealing means provided with a protrusion to be in close contact with the.

Patent Document 12 relates to a mask capable of preventing gas from flowing into the mask without being filtered by a filter sheet, and provides a mask including a nose clip and/or a nose pad.

Patent Document 13 relates to a dust-proof mask that prevents fine dust from entering the respiratory system, and forms an upper cover portion with a nose support portion formed on the inner surface at the top and bottom and a lower cover portion formed with a chin support portion formed with an air exhaust portion, so that a user can use the mask It provides a mask that can be easily worn with the nose support part formed on the upper cover part in close contact with the nose without additional manipulation when wearing the mask.

Patent Document 14 relates to an eco-friendly traditional Korean paper mask. The mask body 100 is formed to fit the curvature of the face to shield the mouth and nose, and the fixing straps are formed on both sides of the mask body 100 and can be hung on the ears. (200) enjoys the unique functions of traditional Korean paper, effectively adsorbing and filtering fine dust, pollutants, and various harmful bacteria, while maintaining a comfortable state for a long time due to excellent breathability, heat retention, quick-drying and antibacterial properties, especially harmful to the human body It provides eco-friendly masks that children and the elderly can use with confidence.

In this way, Patent Documents 7 to 14 have known various means for close contact with the mask and the surrounding area including the nose.

In the prior art, 1) the degree of adhesion is weak even if it is temporarily adhered in the wearing state, and 2) the user's muscles cannot but move, so the adhesion is easily weakened by the movement of the facial muscles, as well as the skin such as the bridge of the nose. Skin damage occurs due to frequent friction with Because it provides a form that strongly compresses the area, in the case of a female user, makeup is removed and therefore avoids wearing it. Since the degree of adhesion varies depending on the level of skill, incomplete adhesion may be achieved for users who are not accustomed to controlling devices or instruments, such as the elderly and children, 7) If a face shield is added, it is still double fixed on the face I have a problem that needs to be done.

As described above, a mask that can be fixed by the second seating area except for the ear and has improved adhesion to the nose periphery has not yet been presented.

As described above, the present invention can provide a mask that is fixed to the face by pressing only a specific part of the face. Compared to the conventional mask, the mask according to the present invention is 1) easy to attach and detach, 2) minimizes contact with the skin including the face during the process of detachment and attachment, and 3) no irritation to the skin even when worn for a long time. 4) Minimizes discomfort such as other musculoskeletal pain including the ear, 5) It can provide consistent fixation force regardless of the user by optimizing the area as well as clearly specifying the area to be pressed, 6) the present application The specific part of the face to be pressed in the present invention does not exert any physical force on the ear as mentioned above, so there is no problem of stress and weakening of concentration due to prolonged wearing.

In addition, the present invention solves the problem of fogging glasses, etc., which is a chronic problem that cannot be solved in the conventional mask by introducing a pressing part. The present invention achieves an effect that can never be achieved in a conventional mask as a mask that can increase the adhesion around the nose while minimizing pressure. Specifically, 7) the degree of close contact with the nose is strong, 8) it not only maintains close contact with the nose even when facial muscles move, but also minimizes friction, 9) the degree of adhesion is improved even by vibrations generated when moving while wearing a mask. It does not weaken, 10) the area of pressure is minimized for close contact, 11) the degree of pressure can be easily adjusted according to the height of one's nose, and 12) the user is unfamiliar with the control of devices or instruments such as the elderly and children. It is also possible to provide a mask that can provide a certain level of adhesion or higher.

The present invention provides only one mask having a binding part, and can provide a mask having an excellent leak rate and wearability because it can respond to each user's face by adjusting whether or not the binding part is detached. In addition, the process of adding the binder can be applied by modifying only a portion while applying the conventional process as it is, so adding the configuration is easy and economical. On the other hand, since masks of various sizes are not provided for the size and shape of the user's face, the possibility of surplus products is low due to the production of small items. This is a more effective use of resource utilization and is also very desirable from an environmental point of view in that it can reduce the rapidly increasing amount of mask waste.

In order to present a clear standard of the user's discomfort and fixing power according to the specific location of the fixing part, the following experiment was performed.

<Experiment 1 : Measurement of fixation force at 1-6 fixation sites>

The pressure felt by the user (PPT) and the pain felt under a fixed pressure (VAS) were measured for each coordinate (x, y) based on the user's face according to FIG. 7 .

Separately measuring the pressure that the user feels pain and the pain felt under the fixed pressure means that when the user increases the pressure according to the location of the muscle, the location of the skeleton, and the thickness of the skin, the fixation power is guaranteed, but the user suffers from pain. This is because there are cases in which a person can feel the pain or do not feel much pain, but the fixation force is not guaranteed.

The user's pain threshold (PPT) was measured for each (x, y) coordinate based on the user's face according to FIG. 7 . The Pain Threshold (PPT) was defined in this experiment as the maximum pressure that can withstand pain.

9 is an exemplary photograph in which a square including a predetermined square among a user's face is actually applied to a person's face in order to perform an experiment, and FIG. 10 is a schematic diagram of an apparatus for measuring PPT.

For the distribution of pressure to feel pain, the pressure to feel pain (pain threshold, PPT) was measured at the corresponding coordinates using an Algometer. Pain threshold (PPT) was measured using PPT equipment in a predetermined rectangular area corresponding to each value of (x, y) based on the user's face according to the present invention located on the subject's face surface. The unit of pressure to feel pain is kg/cm2. The result of inputting the pressure value at which the pain started in the corresponding coordinates and converting the pressure value into a relative color is shown in FIG. 11 . The result of FIG. 11 is an average value of the values performed for 19 people. 11, 12, and 13, the upper table shows the measured values according to the position of (x, y) with respect to the user's face according to FIG. 7, and the measured values are displayed in different colors in the graph below. 1 to 5 displayed on the vertical axis of the rectangle of the lower graph correspond to y values among (x, y) coordinates based on the user's face, and 1 to 5 displayed on the horizontal axis are ( x, y) It corresponds to the x value among the coordinates.

In order to measure the distribution of pain felt under a fixed pressure, the subject's discomfort score (VAS) was investigated after constant tension was applied to the coordinates of each of the predetermined rectangles using an Algometer. The pressure was fixed at 1 kg/cm 2 , and the result of inputting the discomfort level value for each coordinate and converting it into a color relative to the input value is shown in FIG. 12 . The Visual Analog Scale (VAS) is a method used as an evaluation scale for pain by setting the perceived pain level of patients from 0 to 10 and displaying it directly to patients. one of the indicators. The result of FIG. 12 is an average value of the values performed for 19 people.

On the other hand, a new pain index was derived based on the experimental results on the pressure felt by the user and the pain felt under the fixed pressure. The new pain index is a value obtained by multiplying 100 by dividing the pressure that the user feels pain (PPT) by the value of pain felt under fixed pressure (VAS). Select a region that can withstand strong pressure and feel less pain it is to do The results of performing the analysis on the coordinates of each of the predetermined rectangles are shown in FIG. 13 .

In the first experiment of the present invention for the 1-6 fixation site, a clear fixation site could be derived through the three methods as described above, with a value of 1.2 or higher in FIG. 11, a value of 5.0 or higher in FIG. When the value is applied, it was evaluated that it can guarantee fixing power while minimizing discomfort to the user.

<Second Experiment: Measurement of Fixing Force of 1-7 Fixing Sites>

As described above, 1-6 fixed sites were selected through the first experiment. The 1-6 fixation site corresponds to the inside of a square based on the user's face with the angle of the mandible and the zygomatic process as one side.

While conducting research according to the present invention, it was found that the space between the front of the ear canal and the back of the temporomandibular joint could also be used as a fixing site. In the second experiment according to the present invention, additional evaluation was performed on this site. In extending the range of the fixation part to the back of the face, it was recognized that it could be utilized only if the temporomandibular joint was not passed, and this was expanded. Likewise, the range of the fixation area was extended toward the upper part of the face.

The pressure (PPT) at which the user feels pain was measured for each coordinate (x, y) based on the user's face according to FIG. 8 . The measurement method is the same as in the first experiment.

Measuring the user's pain threshold (PPT) according to (x, y) based on the user's face according to the present invention means that the user has pain depending on the presence of muscles, the position of the skeleton, and the thickness of the skin according to the position of the user's face. Because the degree may vary. It means that the higher the pain threshold, the higher the pressure to ensure fixation.

The unit of pressure to feel pain is kg/cm2. The pain thresholds for the corresponding coordinates were written, and the results are shown in FIG. 14 . The result of FIG. 14 is an average value of the values performed for 9 people. In the upper part of FIG. 14 , standards with different colors according to the pain threshold (PPT) are shown. Below 1.2, the pain threshold is too low to be used as a fixation site, and above 1.4 is the most desirable area with the highest pain threshold.

<Fixing force test>

Among the sites derived according to the first experiment of the present invention, 5 sites evaluated to have particularly high fixation power compared to pain were selected and the fixation power was measured by various methods.

The (x, y) values based on the user's face are respectively 1, 2, (1,3), (2,5), (2,2), and (2,4). 3, 4, and 5 sites were named, and a fixation force test was conducted separately for them. After manufacturing a semicircular frame in the form of a frame that presses only the coordinates of a predetermined rectangle while enveloping the face for the 1, 2, 3, 4, and 5 parts (hereinafter, 'frame part'), the semicircular frame presses the corresponding coordinates Whether to maintain the original position of the horizontal frame when returning to the original position after bending the neck by 30 degrees after placing the semicircle frame horizontally (Verbal), or whether the horizontal frame remains in its original position (Flexion), the speed of 3km/h and 5km/h Whether or not the semicircle frame deviated from its original position (Walking) was observed through the walking of h. The experimental results for each are shown in Table 1, Table 2, and Table 3. This is the result of performing the experiment on 3 people is the average value of

15 is an apparatus for measuring the degree of fixation when the frame part is fixed to a specific part of the user with a specific pressure. The elastic force of the device was differentiated into 10g, 30g, and 50g, and the pressure applied to the user's face was changed by drawing a diagram.

The pressure in Table 1 is an elastic force or pressure applied to the user by the frame unit, and the unit is g. Table 1 shows the minimum pressure for the frame part to be in place in the experiments of Verbal, Flexion, and Walking. It can be seen that positions 2 and 4 are low pressure. there is.

Table 2 shows the number of people whose frame part left their seats according to the fixing pressure during the tests of Verbal, Flexion, and Walking. Similar to Table 1, at positions 2 and 4, the frame part did not deviate.

Table 3 shows the results according to the pressure applied by the frame in the area where the movement of the frame does not occur. It can be seen that the frame part does not move even at low pressure at positions 2 and 4.

Table 4 shows the results of measuring whether the frame part is fixed after hanging a weight of a certain weight on the frame part for the five positions.

As can be seen from Table 4, positions 2 and 4 can hold heavy weights even at low pressure. Through the above experiment, it can be seen that the positions 2 and 4 guarantee the best fixing force.

<Measurement of fixing force according to the addition of the pressing part>

The fixing force as the pressing part according to the present invention was added was measured. The pressing part according to the present invention may add a fixing force to the pressing part itself. In order to measure the fixing force according to the addition of the pressing part, the same shape as the pressing part according to the present invention (hereinafter, 'pressing part') was added to the frame of FIG. 15 . 16 is a view in which a pressing part is added to the frame part in order to measure the fixing force according to the addition of the pressing part.

After fixing the frame so that the first fixing position could be the 2nd and 4th positions in the fixing force test, the fixing force was observed by changing the position of the pressing part and the position of the pressing part up, middle, and down based on the nostrils.

17 is a photograph showing the position of the pressing part up, middle, and down with respect to the nostrils.

The fixation force is whether the semicircle frame deviates from the correct position by voicing 'Aei Oh' as in the case of performing only with the frame (Verbal), or walking at 3 km/h and 5 km/h per hour (Walking), The frame was divided into cases in which 10, 20, 30, 40, and 50 g of separate weights were added. This experiment is the average value of the results of the experiment performed on 3 people.

As can be seen from Table 2, when the fixing force of the frame part is set to 30 g, the fixed position did not deviate from the fixed position for verbal and walking regardless of whether or not the pressing part was added.

In order to observe the effect of the pressing part, the pressure of the frame part was reduced to 10 g or less by minimizing the support pressure of the frame part. In this case, even at positions 2 and 4, the minimum weight of 10g can not be supported. Table 5 below shows the experimental results. According to the weight of the weight and the position of the pressing part, the case where the frame part does not deviate from its original position was marked as O.

Referring to Table 5, in the case of the frame part without the pressing part, it was found that both positions were out of position at positions 2 and 4. The degree of deviation from the original position of the pressing part also differed depending on the position, and it was observed that the strongest fixing force was ensured when it was located below the nostrils.

<Measurement of fixing force of (-1,1), (1,-1)>

In the present invention, since the disposable or entry-level mask is very light compared to a general gas mask, etc., the conventional pain is high, but the fixing force is high considering that the mask can be sufficiently fixed to the face even at a value much lower than the fixing force of the frame part used in the <Fixing force measurement> Only this high region was separately selected and the experiment was performed. In this experiment, the above site was added to the 1-6 fixation site, but in the end it corresponds to the 1-7 fixation site.

The experiment was carried out in the same way as <Experiment 1 : Measurement of fixation force at 1-6 fixation sites> and <Fixing force experiment> described above.

FIG. 18 is a result of measuring VAS by adding (-1,1) and (1,-1) to the 1-6 fixation sites. In FIG. 18, number 1 corresponds to (1,-1) and number 6 corresponds to (-1,1). The graph of FIG. 18 measures the VAS for Nos. 1 to 6. Positions 1 and 6 are not preferable as a fixation site because they appear as painful areas when the pressure is 30 g, but it is indicated that they can be used as a fixation site at a pressure of 10 g. 18 is an average value of experimental results for 5 subjects.

19 to 21 are results of experiments with high precision in verbal, flexion, and walking for 1, 6, 2, and 4, which had little pain among the experimental results of FIG. 18 . No. 3 in FIGS. 19 to 21 corresponds to No. 6 of FIG. 18 . From the results of FIGS. 19 to 21 , it can be seen that all four locations in which the experiment was performed can be a strong fixing site that can sufficiently secure the fixing force. In particular, No. 1 showed the best high accuracy in all cases.

As such, in the present invention, an anatomically specific location was clearly set, and various experiments were performed for each area. By deriving a specific area that can guarantee high fixation with minimal force, there is little irritation to the skin even when worn for a long time. A mask that can be provided can be provided.

<Accredited leak rate measurement>

<Example of leakage rate>

25 to 27 in the conventional mask (KF 94) in order to measure the official leakage rate according to the pressing part of the present invention, the first pressing part according to the present invention in a state in which the fitting function of the conventional mask itself is not used This is a photo of a press-on part that can press the third to third press parts manufactured in the form of a metal clip and tried on.

25 to 27, the third pressing part (leak rate Example 1), the second pressing part (leakage rate Example 2), and the first pressing part (leakage rate Example 3) according to the present invention are closely attached to the clips according to FIGS. The official leak rate was measured for the case.

<Leak rate comparative example>

A disposable mask of the KF94 model, which is a conventional mask, was used as a leak rate comparative example. In the mask, a deformable wire is inserted around the nose of the mask for sealing around the nose. The official leak rate was measured with the mask. In Leak Rate Comparative Examples 1, 2, and 3, the leak rate was measured using the conventional KF94 at the position where the leak rate was measured in the leak rate Examples 1, 2, and 3, respectively.

The leak rate was conducted according to the leak rate test method described in the Guide-0349-04 of the "Guideline for Standard Specifications of Health Masks (Citizen's Guide)" by the Korea Food and Drug Administration. The leak rate result of the present invention is the result of the test apparatus and method after being certified by the Food and Drug Administration.

In the table result related to the leak rate below, actions 1 to 5 are for 2 minutes without moving or speaking the head described in the "Guideline for Standard Specifications for Health Masks (Citizen's Guide)" Guide-0349-04. walk ㉯ Move your head from side to side 15 times for about 2 minutes as if examining the wall of a tunnel. ㉰ Move your head up and down 15 times for about 2 minutes, as if examining the roof and floor. ㉱ Say aloud sentences in Korean for 2 minutes. ㉲ is equivalent to walking for 2 minutes without moving the head or talking.

For each behavior, the test was conducted for about 2 minutes, and the average value of 5 times in total was used.

<Compared to the official leak rate results>

Tables 6, 9, and 10 show the third fixing part (leak rate Example 1), the second fixing part (leak rate Example 2), and the first fixing part (leak rate Example 3) of the present invention, respectively, when in close contact with each other is the official leak rate for , and Tables 7 and 11 are the official leak rate results of the leak rate Comparative Example 1 and the leak rate Comparative Example 2. In the case of the leak rate Comparative Example 3, it was impossible to measure the leak rate itself because adhesion was not possible. When the leak rate was forcibly measured, a value of 40% or more was measured, and a practically meaningful value could not be derived.

Table 11 shows the leak rate of Example 4 for the same experiment without compressing the parts of Examples 1, 2, and 3, but only the user's nasal cartilage, when using the nose fitting adjuster according to the embodiment of the present invention. rate is the result.

Table 12 below shows the results of comparing the official leak rates of the leak rate Examples 1 to 3 and the leak rate Comparative Examples 1 and 2 according to the present invention.

Certified leak rate note Leak Rate Example 1 2.05% 3rd fixed part Leak Rate Example 2 0.36% 2nd fixed part Leak Rate Example 3 2.04% 1st fixed part Leak Rate Example 4 0.71% claim 2 fixed part Leak rate comparative example 1 4.12% Less than 11% of KF94 standards are met Leak rate comparative example 2 1.57% Less than 11% of KF94 standards are met Leak rate comparative example 3 - Cannot be measured because it is not fixed

When measuring the official leak rate, leak rate Examples 1, 2, 3, 4 and leak rate comparative examples according to the present invention all showed that the standards of KF94 were satisfied, but all cases of the present invention were compared to leak rate comparative examples This showed a low leakage rate. <Compared to the result of jaw movement>

Tables 13, 15, and 17 show, respectively, a sentence in Korean for 2 minutes with a jaw movement among the leak rate test methods after wearing a mask including a pressing part according to leak rate Examples 1 to 3 of the present invention. say out loud" is the test result performed 5 times, respectively, and Tables 14 and 16 show the results of Leak Rate Comparative Examples 1 and 2, respectively. In the case of ㉱, a lot of leakage actually occurs, but since it is not clearly known within the regulations of the accredited test, an additional experiment was conducted.

As can be seen from Table 13, the mask including the pressing part according to the leak rate Example 1 showed a very excellent value as the leak rate was 1.87% even for the above test. Referring to Table 14, when the conventional KF94 is used at the same location, it was found that 8.02%, which was less than 11%, was met, but showed a leakage rate value of 4 times or more compared to Example 1 of the leakage rate.

As can be seen from Table 17, the mask including the pressing part according to Example 3 of the leakage rate showed an excellent value as the leakage rate was 2.31%. On the other hand, in the case of the leak rate Comparative Example 3, it was impossible to measure the leak rate itself because adhesion was not possible. When the leak rate was forcibly measured, a value of 40% or more was measured, and a practically meaningful value could not be derived.

Table 18 below shows the results of comparing the results of performing only the test having the highest leak rate among the official leak rates of Leak Rate Examples 1 to 3 and Leak Rate Comparative Examples 1 and 2 according to the present invention. There are many cases where users wear masks and work for a long time, and most of them have conversations accordingly. Referring to Table 18 below, the leak rate Examples 1 to 3 of the present invention show almost similar leak rate values compared to the case of Table 12 even in this case, which is a constant sealing even if there is movement of the jaw muscle or facial muscle. It can be confirmed that the In addition, it maintains a low leakage rate regardless of location and muscle use, so that excellent results can always be obtained even if the user is not proficient in wearing a mask.

Leak rate for jaw movement note Leak Rate Example 1 1.87% 3rd fixed part Leak Rate Example 2 0.41% 2nd fixed part Leak Rate Example 3 2.31% 1st fixed part Leak rate comparative example 1 8.02% Less than 11% of KF94 standards are met Leak rate comparative example 2 1.41% Less than 11% of KF94 standards are met Leak rate comparative example 3 - Cannot be measured because it is not fixed

On the other hand, the conventional mask shows a large difference in leakage rate when the user's jaw or facial muscles are stopped and when not, and there is a difference of 4 times or more depending on the location. There is a disadvantage of showing an inconsistent value depending on whether or not it is. On the other hand, in the same experiment, only the user's nose cartilage part is used for the presser according to the embodiment of the present invention without pressing the part of the leakage rate Examples 1, 2, and 3 As a result of measuring the leakage rate using KF94 of the case and comparative example, results similar to Tables 15 and 16 were shown. Even in this case, the result according to the present invention showed a leakage rate value of about 1/4.

<Displacement Experiment>

In order to confirm the displacement of the device for fixing to the face according to the presence or absence of the pressing part according to the present invention, an elastic body fixed only on the left and right sides of the user's face was manufactured, and the change in the position of the elastic body in the nose periphery was observed using a motion sensor.

28 is a photograph of a user wearing an elastic body to which a pressing part according to Leak Rate Example 2 is added in order to conduct a displacement test. The displacement of the portion indicated by the black dot in FIG. 28 was observed. After the user wore the elastic body with or without the press part according to the leak rate Example 2, the displacement of the black dot was observed while speaking "Ai Oh". After obtaining the coordinates from the reference point, the distances were measured and shown in FIG. 29 according to time.

In the conventional mask, even if the user bends the wire around the nose and adheres to it, the adhesion is lowered due to the contraction and relaxation of the facial muscles generated by the user speaking. The dotted line in FIG. 29 shows the result of trying on the elastic body without adding the pressing part according to the leak rate Example 2 as a result similar to this. When the pressing unit according to the present invention is added, it can be indirectly confirmed that the degree of adhesion can be continuously maintained because the displacement of the corresponding part (see the solid line in FIG. 29 ) is small even when the user has a conversation.

In the present invention, since the position change is small, the friction with the skin according to the change is small. This has the advantage of preventing damage to the skin due to friction between the bridge of the nose and the mask when it is necessary to wear a mask for a long time like COVID-19.

At least a portion of the frame body (170, 270, 370) is at least one of the filter body (112, 212, 312), the filter upper surface (114, 214, 314), and the filter lower surface (116, 216, 316) The coupling portion with the filter body (112, 212, 312), the filter upper surface (114, 214, 314), and the filter lower surface (116, 216, 316) is at least one of the inner and outer surfaces of the inner surface and the outer surface. 34 to 45 show various examples in which the frame body can be combined with the filter body.

The coupling portions 180, 280, 380 include fixing portions 184, 284, 384 in direct contact with the first fixing portion; It may include a; fixing portion cover (182, 282, 382) coupled to the outer surface of the fixing portion (184, 284, 384). Embodiments 1 to 3 according to the present invention show that the fixing part covers 182, 282, 382 are separately coupled, but the frame body 170, 270, 370 and the coupling parts 180, 280, 380 are integrated. It is also possible to be molded into

The filter side surfaces (118, 218, 318) are one surface of the fixing parts (184, 284, 384), one surface of the fixing part covers (182, 282, 382), and the fixing parts (184, 284, 384) and It can be coupled with at least one between the fixing part cover (182, 282, 382), specifically, it can be coupled by means of at least one of fitting, hooking, adhesion, adhesion, magnetic force, and fusion.

The fixing parts 184, 284, and 384 are preferably in the form of an inverted 'C' or an inverted 'L' shape. This is to ensure the greatest fixing force with the minimum contact area. Since the fixing portions 184, 284, and 384 are portions serving to fix the mask according to the present invention to the first fixing portion, an elastic body containing silicone having high frictional force and unfamiliar reactivity to the human body is preferable.

In relation to the fixing parts (184, 284, 384), the shape of the fixing part may be any form of polygonal or circular shape, but a 'C' or an 'L' shape in which the periphery is protruded and this shape is inverted is preferable. This is because when the fixing parts 184, 284, and 384 press the skin, the relatively non-pressed skin protrudes to the center of the fixing parts 184, 284, 384 to prevent the mask from moving or rotating in front of the face. Because.

54 is a view showing various modifications of the fixing unit cover (182, 282, 382) according to an embodiment of the present invention. 54 shows a curved shape as an example of the fixing part covers 182, 282, 382, but the polygonal shape is also deformable. Portions indicated by dotted lines in FIG. 54 indicate the fixing parts 184 , 284 , and 384 .

In addition, at least one wing support may be added to the fixing parts 184 , 284 , and 384 . Although the wing support is not shown in the drawing, it is connected to the fixing parts 184, 284, 384 and has the effect of increasing the fixing surface, so that a more stable fixing force can be ensured.

The fixing parts 184 , 284 , and 384 may include an elastic body including silicon. The fixing parts (184, 284, 384) may be integrally formed with the frame body (170, 270, 370), and may be configured in an additional form as a separate material, but considering that they all come into contact with the skin, It must be a material that is harmless to the human body and can guarantee adhesion.

A separate protective layer (see FIG. 51 ) may be added to the outer surface of the filter, and the protective layer may be fixed to at least one of a filter and a frame part. In addition, the protective layer may be made of at least one of a fiber, a polymer resin, a separate filter, a nonwoven fabric, and a metal, and the protective layer is translucent or opaque.

Although not explicitly shown in the drawings of the first embodiment or the third embodiment, a heavy mask or a nose in order to add additional fixing force when vibration is severe or movement is severe; chin; ear; mastoid bone; back of the neck; head of parietal or occipital bone; An auxiliary fixing unit using an auxiliary fixing unit located in at least one of them may be added. A more stable fixing force can be ensured by using the auxiliary fixing unit. However, considering that the mask according to the present invention has basically high fixing force, the auxiliary fixing unit also does not require strong pressure.

The portion pressed by the pressing units 274 and 374 may be in the form of at least one of a point, a line, or a plane, and the pressing portion itself may be in the form of at least one or more. In addition, in order to increase the bonding force of the portion pressed by the pressing parts 274 and 374, it may be configured in the form of a fine protrusion.

In addition, the shape of the portion that substantially applies the force of the pressing parts 274 and 374 may be at least one of a point, a line, a surface, or a solid. As described above, the pressing parts 274 and 374 can be deformed in various forms, but in order to exhibit the effect according to the present invention, at least one of the first pressing part to the third pressing part must be pressed.

55 to 120 show various examples of the pressing unit according to the present invention.

55 shows, as an example, a portion of the mask according to the present invention that presses the filter upper surfaces 114, 214, 314 and the filter upper surfaces 114, 214, and 314 by the pressing parts 274 and 374. The filter top surfaces 114, 214, and 314 according to FIG. 55 are displayed in gray. Dark gray indicates a portion exposed to the outside of the filter upper surfaces 114, 214, and 314, and light gray indicates an invisible portion of the filter upper surface 114, 214, 314.

In FIG. 55 , a solid black line completely surrounding the face indicates the outermost part of the mask. In FIG. 55, the filter upper surfaces 114, 214, and 314 may be elastic fabric or the same material as the filter. The filter upper surfaces 114, 214, 314 can be in close contact with the skin by pressing a portion (indicated by a red or hatched line) including the outer periphery of the nostrils among the filter upper surfaces 114, 214, 314. In the case of FIG. 55, by pressing the outer periphery of both nostrils of the nose, the filter upper surfaces 114, 214, and 314 are stretched or deformed without any special pressure on the cartilage of the nose to be in close contact with the nose.

56 to 79 show in detail that the portion pressed by the pressing unit is in the form of a dot or a line.

56 to 67 are diagrams only for the upper surface of the filter and the pressing part for pressing it. Marked in gray is an example of the filter upper surface according to the present invention. The upper surface of the filter may cover the nostril and its periphery ( FIGS. 56 to 58 , 62 to 64 ) or cover the upper end of the cartilage and its periphery ( FIGS. 59 to 61 , 65 to 67 ).

In FIGS. 56 to 67, black dots indicate a portion where the presser presses the filter upper surface from the outer surface of the filter upper surface toward the user's face. A dotted red circle indicates a portion (hereinafter, 'supporting part') in which the pressing part is supported or fixed. A black line in the center and a red waveform in the periphery indicate that the part to be compressed is in the form of a line. Fig. 55 also shows the shape of the line where the pressing part is pressed. The position of the black dot that presses the upper surface of the filter can be changed by elasticity.

56 to 67, the pressing part is in the form of a spring having elasticity, and one end is fixed by a supporting part and the other end presses the filter upper surface from the outer surface of the filter upper surface toward the user's face. Between the part where the pressing part presses the filter upper surface and the part where the pressing part is fixed is a straight line ( FIGS. 56, 57, 59, 60, 63, 68) or a curved part ( FIGS. 58, 61, 62, 64, 65) is formed One or more bends ( FIGS. 62 and 64 ) are also possible.

A shape having a straight line or a bent part can be changed in design depending on the direction in which the pressing part is pressed. The direction in which the presser presses on the outer surface of the upper surface of the filter is a direction perpendicular to the user's skin (FIGS. 56, 57, 59, 61), the direction of wrinkles formed on the user's face, or a direction perpendicular to the wrinkles formed on the user's face ( 62), a direction along the outer periphery of the user's nose (Fig. 63), an inward or outward direction (Figs. 57, 58, 64) of the user's outer periphery, or a muscle direction around the user's nose (Figs. 60, 65) ) or a complex combination of the above directions ( FIGS. 61 and 66 ).

On the other hand, the relative position pressed by the pressing unit may or may not be fixed. 56 to 67, the position of the black dot that the presser presses may be changed by elasticity.

56 to 58, 62 to 64, the portion pressed by the pressing unit corresponds to the first pressing unit, the second pressing unit, or the third pressing unit, and FIGS. 59 to 61 and 65 to 67 correspond to the second pressing unit. 56 to 67, the pressing part is symmetrically disposed around the nose. In the example of FIGS. 56 to 67, one pressing part is configured in the form of a dot for one pressing part. However, one ( FIGS. 56 to 63 , 65 , 66 ) or two ( FIGS. 64 and 67 ) parts fixed to the part supported by one pressing part is configured as an example.

68 to 73 are in addition to the configuration of Figures 56 to 67, a connection portion for connecting the pressing portion symmetrically arranged around the nose is added. However, even in the configuration of Figures 68 to 70, the elastic spring-shaped central portion still does not directly press the nose. In this case, the spring forming the pressing part is composed of a single body.

74 to 79 show various embodiments for a case in which two or more supporting parts are supported in the configuration of FIGS. 26 to 67 and two or more bent parts. This structure can be changed in design according to the shape of the device attached to the face or the part to be pressed. The various shapes of FIGS. 74 to 79 may also be configured by deforming one body.

This shape is also deformable depending on the position of the support. If the support part is formed near the face, the pressing part will be arranged along the facial part, and if the support part is formed at a position spaced apart from the facial part, the pressing part is configured in a form away from the face. As such, the spring-shaped elastic body can be variously deformed using the three axes of the x, y, and z axes.

80 to 88 show in detail that the portion pressed by the pressing unit is in the form of a surface.

80 to 88, the figure filled with black indicates that the portion that the presser according to the present invention presses from the outer surface of the upper surface of the filter is in the form of a surface. Figures 80 to 93 are two pressing parts that are not connected to the cartilage are symmetrically arranged, and Figures 83 to 85 are connected to the middle part. 80 to 88 are cases in which the pressing part includes all points, lines, and surfaces. Even in this case, the material constituting the pressing part may be integrally formed using a material having elasticity, such as metal.

89 to 106 show a case in which the pressing portion or the additional pressing portion is in the form of a plane, and the pressing portion or the additional pressing portion is three-dimensional. 89 to 106, the black side shows the side of the pressing part when viewed from the upper part of the user's face to the lower part. The gray color around the nasal cartilage indicates the additional pressing part, and the additional pressing part is also composed of a three-dimensional shape. The pressing part defined in FIGS. 89 to 101 is a three-dimensional form with elasticity, and may be composed of one body or multiple bodies. A portion in which the pressing portion presses the filter upper surface is also a surface, but the portion in which the pressing portion is fixed to the support portion is also a surface.

107 to 109 show another three-dimensional shape of the pressing part. The pressing part is made of an elastic material such as foam or silicone, and the pressing part is in the form of a surface or a microprotrusion. The portion fixed to the support is in the form of a surface, and the configuration of FIGS. 107 to 109 presents various forms capable of dispersing the pressure applied to the user's face as examples.

110 to 120 show various examples of a form capable of movement including rotation, movement, and twisting while the pressing part and/or the additional pressing part are fixed to the support part. As a specific movement form of the non-limiting example of the pressing part, various mechanical movements such as sliding, rotation, and hinge folding may be applied.

In the embodiment of FIGS. 118 to 120 , an object having a changeable shape, such as a foam, an air cap, silicone, or a spring, is fixed to the support and a pressing part is connected here again to apply a non-mechanical motion.

119 to 120 show various examples of the fixing parts 1-3 and the fixing surfaces for pressing the fixing parts of the mask according to the present invention.

In FIGS. 121 to 126, the gray area indicates a portion where the fixing surface presses the user's face, and the black solid line is an example of the frame portion and indicates various embodiments of the frame portion made of an elastic material. The frame part is bent even on the area indicated by the gray area, so that the frame part itself can directly press the face. In the notation of the drawings, the frame part is marked only with lines, but it is easy to change it to a surface with elasticity, so a specific example thereof is omitted. In addition, since the frame portion is bent, the portion in which the frame portion itself can directly press the face can be changed to a surface.

In FIGS. 121 to 126 , only the cross section of the face is shown, but since the frame part is in the form of enclosing the face, the fixing part is also arranged in a part not shown in the drawings.
