Description

Mask comprising a control unit {Mask comprising control unit}

The present invention relates to a mask comprising an adjusting portion. Specifically, unlike a conventional mask, the mask can be fixed to the face by not being fixed to the ears but by close contact with the face, the opening range or strength of the mask can be adjusted, and the mask has improved sealing properties around the nose.

Masks have been limitedly used as products related to diseases. It was used as an aid to not spreading one's disease to others or to prevent infection from others. Due to the influence of yellow dust and fine dust, many people wear masks, but this is also to prevent diseases.

The pandemic of COVID-19 (coronavirus infection-19) has changed the perception of masks. It was treated as precious enough to cause a shortage of masks, and it was socially learned that only masks had a great effect on preventing diseases. The experience of living in a state of wearing a mask most of the day was also widely shared. The negative view of covering the face by wearing a mask was alleviated regardless of East or West.

Masks have become a daily necessity like glasses. Every household has a constant stockpile of minimum quantities. It has become very natural to wear a mask even in the face of pollen in spring, yellow dust, car fumes in summer, and a mild cold in winter. As if wearing glasses is not strange at all, wearing a mask has also become a very natural culture.

As the temporal, spatial, and cultural environment for masks has changed rapidly, a new concept of mask that transcends the current concept is needed. Conventional masks are manufactured considering only the functionality of temporary wear in abnormal cases, so a new type of mask that can be worn for a long time as well as always and takes into account the user's fashion is needed.

A conventional mask consists of a fixing part for fixing the mask to the face by hanging a string on the ear, and a main body part for covering while pressing the nose and mouth. When the mask is worn for a long time, pressure marks are generated on the face and ears along the periphery of the string, which is the fixing part.

When wearing a mask, it is necessary not only to adjust the length of the string, but also to adjust the strength and direction of the nose compression part and the area around the chin to suit the face. Nevertheless, the problem of fogging on the glasses still persists because the sealing is not perfect.

inventor of the present invention

conducted a preliminary study to identify the problems of the conventional mask. A study was conducted on the leakage rate according to the length of the mask strap and the pain felt when wearing the mask. In the present invention, a KF94 mask was used as a conventional mask, and a study was conducted with 9 participants.

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

The face length referred to herein 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 as the length of the face measured using Morpheus.

If the length of the mask strap is reduced, the leak rate can be reduced, but pain in various parts has been observed due to long-term wearing.

1 is a schematic diagram showing a location where pain due to wearing a conventional mask is observed. A qualitative evaluation was conducted immediately after wearing the degree of pain for the specific parts of the face ① to ⑧ shown in FIG. 1 and after wearing it continuously for 8 hours. When wearing the mask for 8 hours in a row without adjusting the length of the strap, it was observed that the degree of pain increased significantly only in the area ⑥ (behind the ear). Even when the degree of pressure on the face is weak, it is analyzed as pain caused by the mask string being continuously fixed to the ear.

When worn continuously for 8 hours with the leakage rate lowered by adjusting the strap length of the mask to 120% of the face length, it was found that pain increased in various parts including part ⑥. It was found that the pain increased significantly in areas ③ and ⑦, which were separated from the ear, including area ④. Areas ③ and ⑦ are the areas where pain is expressed at the myofascial tender points, and are easy to cause headaches. It can cause shoulder pain.

The inventor of the present invention can confirm that wearing a mask for a long time through the above preliminary research can cause pain in other musculoskeletal systems other than the ear. The various pains caused by wearing a mask can also reduce concentration and interfere with study or work. Recently, when a mask is worn for a long time, the problem of deformation of the ears of growing children or teenagers has also emerged.

The present invention is to solve these problems at a fundamental level, and the present invention was derived through the process of developing a mask that can be fixed by the face except for the ears. Even if the user does not wear it intentionally, not only the leakage rate is high, but also the aesthetic aspect is considered.

Patent Document 1 relates to a mask that is easy to wear, including a holding portion spanning the curved portion of the front face, and an elastic contact portion extending from the holding portion to contact the upper end of the cheekbone and extending along the contour of the face to the side of the face near the ear. A frame and a mounting hole into which the frame is detachably inserted into the inside are provided, and are detachably mounted on a main body made of a fiber band material having elasticity and an inner surface of the main body, covering up to the nose and mouth periphery of the face, The frame is provided with a mounting hole detachably inserted therein, and is composed of a filter covering the nostrils and the mouth, so that the holding part and the elastic contact part are in close contact with the face by the elastic force of the elastic contact part of the frame. it's about keeping The purpose of Patent Document 1 is to stably adhere to the user's face without causing discomfort to the ears, and to have a structure in which the main body and the filter are detachable, so that the filter can be replaced and used independently by separating the main body or filter according to the use environment. It is in providing a mask that can do this.

In Patent Document 1, a frame including an elastic contact portion extending from the mounting portion to contact the upper end of the cheekbone and extending along the facial contour to the side of the face near the ear is widely disposed in a region including the vicinity of the cheek. In this case, the weak skin area is continuously stimulated, and when worn for a long time, the user not only leaves marks on the face but also feels uncomfortable.

Patent Document 2 relates to a neck warmer for blocking fine dust, which is formed in a cylindrical shape, and includes a neck cover portion covering from under the eyes to the neck of the face when worn; a sealing cover portion formed spaced apart from the user's nose and mouth to cover when worn; A pressure ring part formed on the rim of the upper end of the neck cover part so that the upper end of the neck cover part is in close contact with the face; And it relates to a neck warmer including a filtering unit for filtering air by the nose and mouth, protecting the face and neck as well as blocking fine dust from entering the respiratory system. The purpose of Patent Document 2 is to efficiently block fine dust, to protect the neck and face, and to secure the effectiveness of blocking fine dust. We present a functional neck warmer that prevents

A representative problem of the method using the rubber band of Patent Document 2 is that 1) detachment and attachment are very inconvenient. In addition, 2) there is a concern that the makeup may be erased due to chafing of the face during the attaching and detaching process. 3) When worn for a long time, the user not only leaves marks on the face, but also feels uncomfortable.

Patent Document 3 relates to a wearable mask, a body that covers and protects the mouth of the user's face; and a face fixing member connected to the main body and brought into close contact with a part of the user's face when the user wears the wearable mask. Since Patent Document 3 adheres to a part of the face through a concave groove when worn on the face, it is not necessary to form a hanging tool such as a string added to the mask, thereby reducing manufacturing costs, and even if the body is formed as a disposable product, only the body It is to provide a wearable mask that can be used semi-permanently by replacing it.

In the case of Patent Document 3, 1) there is a risk of leaving marks on the face due to continuous wearing, and 2, it is difficult to ensure a consistent fixing force because a clear criterion for the pressed surface and the pressure to press it is not presented.

Patent Document 4 is a system corresponding to the solid based on the elasticity of the material used for the mask, the length from the jaw to the tragus, the position of the cheekbones, etc., from adults to children, and the face, chin, and frontal area It relates to a face mask that just fits each part of the back. The purpose of Patent Document 4 is to provide a drawing method and a mask corresponding to the three-dimensional shape of a sheet-type face mask suitable for medical supplies or cosmetic purposes that fit the face, chin, and frontal area and replace bandages, bandages, and eye patches.

Patent Document 4 corresponds to the prior art of increasing the stress on the ear mentioned in the present invention as being put on the ear and using its tension.

Patent Document 5 relates to a mask cover that allows a mask to be worn on the face without ear straps. The purpose of Patent Document 5 is to provide a mask with good ventilation of the mask cover and to enable deformation according to the curved surface of the face using a material having excellent elasticity.

In Patent Document 5, 1) it is inconvenient to wear in that a separate anchor member must be attached to the face, and 2) there are concerns about skin damage due to scars on the face or continuous stimulation depending on the surface to which the anchor is attached. there is

Patent Document 6 relates to a body loosening prevention and improvement device, which reduces manufacturing cost, enables attachment to the head and other parts, and allows body loosening prevention and An improvement tool is provided, and the relaxation prevention and improvement tool is formed by integrally connecting a branching portion that can wrap the back of the head to the base covering the area extending from the top of the head or front of the head via the parotid root to the tip of the chin and the lower part of the chin.

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

On the other hand, the problem of being lifted without being accurately adhered to the face is a problem commonly found in goggles, gas masks, and VR headsets, including masks. Compared to other parts of the face, the periphery including the nose is more curved, the skin is thin, so there is almost no buffering effect, and the height is high, so it is difficult to accurately adhere to the face. Also, it is 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 or the like is inserted or attached to the surface of the mask, including the nose, but it still does not adhere accurately to the face. Most masks deform metal such as wire to make the mask adhere to the face for a while, but since there is no supporting part, gaps are easily created according to the movement of the facial muscles. This problem is very simple and seems to have already been solved, but in reality it is an unfinished part that has not been solved for a long time.

The movement of the facial muscles caused by conversation or the like causes the movement of the mask. When you have to wear a mask for a long time, such as COVID-19, skin damage occurs due to friction between the bridge of the nose and the mask. Medical staff such as nurses put a band or bandage on the bridge of the nose and wear a mask on it to prevent skin damage caused by frequent friction.

The gas mask can increase adhesion with the face by compressing the surrounding area including the nose with an elastic sealing part such as silicone through a band mounted behind the head. In this case, the force to press the peripheral area including the nose is relatively large, making it difficult to operate for a long time. In addition, the problem of leaving marks on the face and avoiding women is also a task to be solved.

Masks and gas masks are devices that block air flow, but VR headsets require both air flow and light blocking at the same time. When wearing a VR headset, if the peripheral area including the nose is not sealed, a problem of concentration deterioration due to light exposure occurs. All currently released products also do not seriously consider these problems and present unfinished technology as a solution that presses hard like a gas mask.

Patent Literature 7 relates to a mask for the purpose of providing a function of preventing spillage of eyeglasses, eliminating breathing problems, being able to select a filter portion with optimal pores without leakage of the respiratory tract. It consists of a fixing frame part with good adhesion to the skin contact part, a filter part that can be separated and adhered 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 expand the contact area by the tension of the mounting part, and a shape-memory resin or skin-adhesive resin that shrinks at 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 deformation caused by conversation and facial expression changes is used. The filter part can be separated from the fixing frame part and provides a mask capable of selecting a necessary material according to the purpose.

Patent Document 8 relates to a mask comprising a portion that seals the nose, and provides a mask having an improved nose-close portion that covers at least one of the user's nose and mouth because breathing gas is supplied under positive pressure, and a 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 inner layer pleats, 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, and the inner layer The creases are formed by extending and folding the inner layer surface, and the inner layer pleats and the outer layer surface cover the nose pad at the same time, providing a mask in which protrusions corresponding to the nose pads are formed on the mask body.

Patent Document 10 relates to a close-fitting mask equipped with an elastic band, and constitutes a secondary close-fitting part having elasticity and flexibility along the rim of the mask body, and wraps the user's nose on the upper part of the inner side of the mask body for close contact A nose pad is provided, and a lower side film is provided in the form of a closed curve downward from both sides of the nose pad and wraps around the nose and mouth. It is characterized by constituting the close contact part and providing a separate elastic band having elasticity at the upper position as one side of the secondary close contact part to increase the close contact force of the nose pad 40 to prevent upward outflow of internal air. .

Patent Document 11 relates to a mask, the center of which is provided with an accommodation groove in the inner upper part of the cover for accommodating the bridge of the nose while being inserted, and is inserted into the space formed between the bridge of the nose and the cheekbones on both sides under the eyes of the face on both sides of the accommodation groove. 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 entering the inside of the mask without filtering through the filter sheet, and provides a mask including a nose clip and/or a nose pad.

Patent Document 13 relates to a dust 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 with a chin support portion formed with an air discharge portion so that the user can use the mask. Provides a mask that can be easily worn in a state in which the nose support portion formed on the upper cover portion is in close contact with the nose without separate manipulation when worn.

Patent Document 14 relates to an eco-friendly traditional Korean paper mask, a mask body 100 formed to fit the curvature of the face to shield the mouth and nose, and a strap formed on both sides of the mask body 100 to be worn on the ears. It enjoys the unique functions of Korean paper, including (200), effectively adsorbs and filters fine dust, contaminants, and various harmful bacteria, while maintaining a comfortable state for a long time with excellent breathability, warmth, quick-drying, and antibacterial properties, especially harmful to the human body. It provides an eco-friendly mask that can be used safely by children and the elderly.

As such, Patent Documents 7 to 14 disclose various means for close contact between the mask and the peripheral portion including the nose.

In the prior art, 1) the degree of adhesion is weak even if it is temporarily adhered in the worn state, and 2) the user's muscles are inevitably moved, so adhesion is easily weakened by movement of the facial muscles, etc., and skin such as the bridge of the nose Skin damage occurs due to frequent friction with the face, 3) If the user moves while wearing a mask or VR headset even without movement of facial muscles, the degree of adhesion is weakened by the vibration, and 4) The close contact part is like the nose pad. It provides a form of strong pressure on the area, so female users lose their makeup and avoid wearing it. 5) In the case of some gas masks, only strong pressure is possible because the degree of pressure cannot be adjusted, and 6) Since the degree of adhesion varies depending on the level of skill, incomplete adhesion may occur for users who are not accustomed to adjusting devices or instruments, such as the elderly and children. I have a problem to do.

That is, a mask that can be fixed by the face except for the ears and has improved adhesion to the nose area has not yet been proposed.

Meanwhile, the user's face has various shapes and sizes according to men and women of all ages. Until now, masks have been sold only according to a few sizes targeting all users.

The size and shape of the user's face should also be considered in order to improve the adhesion method to the nose area while increasing the fixing force to the face.

Patent Document 15 is a conventional mask fixed to the ear using a string, and such a mask only mentions a technique for adjusting the string length so far. Patent Document 16 also describes only a configuration for adjusting the string length as a technique similar to this.

If there is no strap to fix the ear as in the present invention, the mask must be fixed by pressing the user's face, but in any of the patent documents mentioned above, the size of the mask itself that presses the user's face is adjusted or the tension thereof is adjusted. technology has not been disclosed.
