A mask structure for capturing coronavirus, its sterilization method, and manufacturing method.

Abstract

We provide a separate-type mask in which the inner lining of the mask body can be replaced. [Solution] The means to improve the "disposable" product to replaceable is to blend bamboo pulp / cotton, linen, silk / various fiber yarns for the exterior (main body) to exhibit "antibacterial properties / quick-drying / moisture-wicking / smooth feel / silky touch" and ensure a range of motion for speech (jaw and lips). The "interior part" is separated, and two or more spare sets are prepared for repeated replacement. When going out for long periods, replace with a spare, and upon returning home, sterilize the replacement spare by irradiating it with microwaves from a "microwave oven" and "sunlight". The main body's constituent material is preferably a non-magnetic material made of bamboo fiber, and a material that has been pre-confirmed not to be affected by "microwave oven" irradiation is identified. "Dirt on the exterior part" should be washed about once every few months, and "dirt / odor on the interior part" should be washed repeatedly with soap or surfactant as needed, sterilized with sunlight or an induction cooker, and reused.

Description

[Technical Field] Field of Invention

[0001] Regarding masks for protection against influenza / coronavirus. Japanese masks include "Iwami Ginzan" dust masks and "toilet odor-blocking" nose pouches made of purple crepe ( Strings attached to both ears The structure is said to be the origin. [Background technology]

[0002] Corona aerosol size is 80-220 nm Conventional masks are merely protective, and the risk of infection for positive individuals cannot be avoided. Making the filtration mesh finer limits the ability to secure exhaled air. The coronavirus has evolved ahead of vaccines, seemingly "provoking" humanity as if to mock us.

[0003] Conventional nonwoven fabric masks filter droplet aerosols, but the relationship between ensuring respiration and the mouth opening ratio is such that increasing the protective filtration capacity leads to respiratory difficulties, and a mask that balances sterilization function and ensuring respiration has not yet been developed. Conventional gauze masks filter droplet aerosols, and concerns that the wearer could become infected have not been eliminated.

[0004] Japanese masks include "Iwami Ginzan" dust masks and "toilet odor-blocking" nose pouches made of purple crepe ( Strings attached to both ears The structure is said to be the origin. Both commercially available gauze masks and non-woven fabric masks are "disposable," meaning that captured viruses may still contain risk factors for the wearer's own infection, and there is a risk that the captured viruses could pass through the healthy person's airways and multiply in the alveoli.

[0005] It is said that a cough from a person with a cold releases 100,000 airborne particles, and a sneeze releases 2 million. Masks are particularly effective in preventing mass infections in densely populated areas of island nation Japan, and have a track record of suppressing numerous influenza outbreaks since the Spanish flu (1918-1920) global pandemic. Combined with Japan's unique spirit of self-sacrifice, masks have become a staple for "patients" and are still worn by tourists in Japan today.

[0006] Globally, there is debate and both support for and opposition to "self-sacrificing" infection prevention. Vaccination is the primary method, masks are a reactive approach, and there is a demand for inexpensive, improved versions of disposable masks that can continuously demonstrate sterilization effectiveness.

[0007] Even in this global pandemic, the Black Sea (salinity 3~9% / surface Around 18‰ / water depth Approximately 20% over 100m / A depth of 200m 22.36% ) and countries with extremely high salinity levels compared to the world average (3-4%), as well as the region along the northern coast of southern Ukraine and the desert areas of the Gaza Strip, are areas barren from vegetation. TV footage and news reports show that masks are "not needed" and there is no coverage of the coronavirus outbreak, which is clear evidence of the effectiveness of crystalline salt. Testing by [public institutions] is essential, but there are no Level 4 testing facilities in the country, so requests were made to testing facilities in neighboring countries, but were dismissed and laughed at, and this situation continues to this day. [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] ▲1▼Instead of the conventional disposable mask body, this mask adopts a "separate type" design where the inner lining can be replaced. ▲2▼The main function and structure of the device is to ensure the normal breathing volume of an adult, to ensure close contact with the contours of the facial muscles, and to secure the amount of air for adult breathing in the space (5 seconds) that is created in the gaps during the movement of the jaw when speaking. ▲3▼The refined salt impregnating the inner lining is 220g of table salt per 1 liter of water, which is the physiological salt concentration for humans (0.9%). Marine organisms also die when the concentration rises to a high level of +1.1%, and in humans, the heart stops if the blood pH drops by 0.35. All living organisms maintain life activities by regulating the concentration of an aqueous solution of the element [K / Na (sodium / potassium)] inside and outside the cells through osmotic pressure. Regardless of the type of virus, the salt crystals in the inner gauze stop the aerosol proliferation activity. ▲4▼The mask body and interior sterilization employ microwave sterilization, which uses ultra-high frequency irradiation from a microwave oven (250 million times / second) to completely kill captured viruses and bacteria. ▲5▼As an alternative sterilization method to a microwave oven, we will use sun drying (sunlight) and ultraviolet rays. ▲6▼This is a method for cleaning the gauze mesh (spare gauze) used repeatedly in the interior of the product. ▲7▼The aggregate material for the exterior of this invention is copper / aluminum and bamboo / plastic, which are non-magnetic metals. Copper does not generate heat above 200°C in a microwave oven, has a sterilizing effect, and is a preferred material for three-dimensional aggregate. [Means for solving the problem]

[0009] To improve the "disposable" product into a replaceable one, the outer casing (main body) is made of a blend of bamboo pulp, cotton, linen, silk, and various fiber threads to achieve "antibacterial properties, quick-drying properties, moisture-wicking properties, a smooth feel, and a silky texture," while ensuring a full range of motion for speech (jaw and lips). The "interior section" is separated, and two or more spare sets are prepared for repeated replacement and reuse. When going out for extended periods, replace the part with a spare, and upon returning home, sterilize the spare by irradiating it with microwaves from a microwave oven and sunlight. The main body's constituent material is preferably a non-magnetic material made of bamboo fiber, and a material that has been pre-confirmed not to be affected by microwave irradiation will be identified. For exterior dirt, wash it about once every few months. For interior dirt / odor, wash it repeatedly with soap or a surfactant as needed, sterilize it in sunlight or on an induction cooktop, and reuse it.

[0010] Conventional masks are filtration type (strainer type), and when eight or more layers of "medical gauze mesh" are stacked in the inner lining, the plain weave cross section (intersection of uneven surfaces) forms a space with a wire diameter φ and a space equal to the number of layers stacked, and the 3D space of the main body becomes an auxiliary tank for air, allowing air to escape between breaths. Adult / 450m 1 It functions as a "framework structure" to ensure sufficient exhalation volume.

[0011] For the interior gauze of this case, medical gauze mesh is used in principle. When using the pre-treated "dry gauze" which has been boiled (sterilized for 5 minutes) with an aqueous solution of saturated purified salt, the virus will pass back and forth while meandering through the laminated space and come into contact with the crystal salt and be restrained. The air in the 3D space of the main body applies the principle of atmospheric pressure where the exhaled air pressure assimilates to the external air pressure in an instant. The structure of the twisted yarn of the gauze where virus / bacteria / pollen floating particles (positrons ++ ) are entangled is the restraint principle. This restraint speed is based on the principle that the crystal salt exposed on the gauze has a deliquescent viscous surface, and oral bacteria are captured by the salt crystals at an electrical speed.

[0012] The microwave penetration rate in Japan is 97%. In countries with low penetration rates, for the microwave wavelength of sunlight at 200 - 380 nm, even in cloudy skies, it enters the atmosphere, and a natural sterilization method of mummifying with "ultraviolet rays" of air drying and sun drying is applied. When the gauze is irradiated with a microwave oven, the captured organic matter (protein) will turn black and char, and the fibers will carbonize and break into pieces. This charring phenomenon is evidence that the virus and organic matter are burned and destroyed, and in this case, it is used as a marker for disposal.

Effects of the Invention

[0013] The international standard for gauze is 1 cm 2 with 12 (twisted yarns) and the wire diameter is 0.4 mm. In a square, there are 12 -4 of 144 holes. For a two-fold, it is 144 4 which is 576 holes. Below, for the third to eighth sheets, 2,359,296 holes are formed. For the gauze area (7.5 × 12.5 cm), there are 220 million meandering holes, and it is calculated that with one exhalation, it contacts and passes through about 500 million holes at 20 ± 5 times n / 1 minute.

[0014] The external structure of this case is an atmospheric storage tank. Plastic copper / aluminum is a material that can maintain a three-dimensional structure and adjust the gap of the facial shape. It ensures the air volume of the nasolabial fossa / zygomaticus muscle during the breathing interval. The facial movement during conversation is the jaw of the upper lip vermilion part. The skin contact feeling and low friction make the movement of the outer periphery of the lower jaw "smooth", and it is a structure that can also be fixed to pet dogs and cats. The internal structure of this case captures airborne particulate matter according to the law of electrostatic ion attraction. It adheres to the wearing frequency time, and the salt contained in the exhaled breath adheres to the twisted yarn, increasing the crystal salt. Its viscous capture performance lasts semi-permanently and can be used unless it gets scorched (amino-carbonyl reaction) in a microwave oven.

Example

[0015] 500 cc of water and 20 g of refined salt were added to an aluminum pot (inner diameter 240 mm, depth 140 mm), and it was heated to boiling with a cooking IH heater. The original medical gauze (in a bag) of "width 30 cm × length 5 m" with the original folded state was directly put into the boiling pot, and "degassing" was carried out while holding it down with tongs. After 5 minutes, it was taken out onto an enamel tray and dehydrated by pressing and tapping with tongs.

[0016] The dehydrated original fabric was spread with rubber gloves, and the double-folded (width 30 cm × length 2.5 m) was dried for 1 hour by the window (open) at an indoor temperature of 23°C on a folding cloth hanger.

[0017] The dried gauze with a width of 30 cm was wound around an aluminum plate dimension (thickness 3.3 mm × 100 mm) four times to form a double-folded gauze with a width of 7.5 cm, placed on a turntable dish (diameter 25 cm) of a 500 W (watt) microwave oven and irradiated (for 40 seconds). Then, the "wound gauze" was removed from the aluminum plate, cut to a length of 12.5 cm with scissors, and the four corners were lightly ironed to produce 20 inner gauzes of this case.

[0018] The structure of the concave and convex parts where the gauze twisted yarns of this case cross (144 mesh / cm 2 ) is explained with a wire mesh as follows: The mesh pattern of the wire mesh is the same as that of gauze. The shape where square meshes intersect is a plain weave of 12 warp and weft threads per 1 cm (144 meshes), and at the position where the wire diameter of φ0.4 mm overlaps, a concave-convex space twice the wire diameter of φ is formed at the upper and lower intersection points. This concave-convex is a space of φ0.4 mm 2 and a gap of 0.4 mm (0.8 mm thickness) is generated vertically every time one sheet is stacked. The principle is to "shift" by half. For the air inlet and outlet, the twisted threads of the mesh meander endlessly in both vertical and horizontal directions, and both the floating particles entering and the mucus of the exhaled breath are captured by the crystal salts of the gauze. Respiration is about once every 20 seconds ±5 and the atmospheric pressure fills the mask within 1 / 7000 seconds through the gap of the outer peripheral ring, based on the principle of instantly becoming the same atmospheric pressure as the atmosphere. This case is based on the principle of "shifting" both vertically and horizontally by half for the square gauze mesh (mesh pattern). For each additional sheet of the mesh pattern, the holes become smaller, such as "[10 -4 " and the number of meshes of 8880 in an 8-sheet roll indicates a non-breathable numerical value. However, for the wire mesh, no matter how many sheets are "shifted" or stacked, the mesh shape remains unchanged. Even if the air passage meanders, the air volume in the laminated space remains the same, and the principle of atmospheric pressure that fills the air of adult exhalation (20 ± times per minute) functions.

[0019] Furthermore, it is a bandage roll for hemostasis with a complex 3D shape. The concavities and convexities and the meandering openings of the mesh pattern increase randomly, which is a first aid for wounds. The specifications of the gauze mesh are also the same internationally. Regardless of the season or cold or warm conditions, from desert areas to Benkei / Ushiwakamaru, it is lightweight and the adjustment of layering is in line with the great invention of the ancient people's [clothing] and the structure of [inner gauze mesh].

[0020] The "inner cork" described in claim 8 is a wine cork. It is said that the deliciousness of sunken ships for thousands of years is special. The "preservation of mummies" in Egypt is a bandage roll, and the skin serves as a closure plate for air movement, showing a [6000-year preservation] record. The [inner cork] of this case has achievements in preventing the invasion of fire and bacteria in the medical field and the school warehouse construction of Shosoin's "treasures", long-term deterioration, and the preservation of large sculptures.

[0021] In particular, for filtering / containing nuclear contaminated water, bandage wrapping is used in the "drain pipes / exhaust ports" as shown in the [photo], employing a strainer structure that filters only water and gas, and running the drain pipes over the sea with numerous (depressurized) exhaust ports. By piping in a spiral / hairpin curve pattern, the temperature difference between land and sea will cause the "fog nucleus / sea fog" phenomenon, and the "coagulation nuclei" that can be reproduced day and night can also be used as an application of gauze filtration devices.

[0022] Hemostasis in injuries is achieved by wrapping with gauze / bandages. When blood at the wound site comes into contact with air, platelets immediately coagulate, forming a waterproof flange that prevents bacterial invasion. The skin-to-skin contact is gentle, stopping bleeding precisely at the point, without hindering the complex contours and joint movements of the human body. Rarely, during surgery, the body may "mistaken" the gauze for flesh, absorbing so much blood that it becomes almost unnoticed. (This proposal uses aerosols.) This greatest invention of gauze, the greatest invention of humankind, is a product of the pioneers of bandages and gauze, which will continue to be passed down through generations without changing its form in modern and future medicine.

[0023] Figure 1 shows a bandage photograph demonstrating its ability to fix complex shapes. Bandages are versatile items that can be wrapped around the complex shapes of the human body, from the head to the limbs, fingertips, muscles, and skeleton. They are hygienic, small enough to carry anywhere, and excellent for self-treatment in emergencies.

[0005] Shows the muscle area around the mouth. The contact area with the exterior of this invention is the facial contours of the philtrum, levator anguli oris muscle, upper lip, white lip area, red lip area, and upper lip constrictor muscle. Conventional masks require a structure that tightly seals the gaps, while this invention, conversely, features a structure that utilizes the gaps. TIFF2026059687000002.tif91122

[0025] The [nasal cover / nasal crown] is based on the image of "Nezumi Kozo" (a famous Japanese thief) where water vapor glows white in the moonlight due to a 13°C temperature difference in the dark night (exhaled air 36°C / outside air 20°C). Its primary purpose is to eliminate odors from the nose, like in the toilets of court nobles, and the philtrum, levator anguli oris muscle, and upper lip area, which are within the contact area of ​​the "mask," are exposed. TIFF2026059687000003.tif85100 Modern lip-seal masks (commercially available masks) are not the orthodox style of the Edo period, This proposed [inner gauze mask] is the orthodox method for preventing infection among modern people. (Copper wire utilization effect)

[0026] Copper has been considered a highly toxic substance only in Japan, and nowhere else in the world. Even today, Wikipedia (the encyclopedia) lists it as a highly toxic substance. However, bronze and brass / copper alloys are safe and are essential elements for humans and animals; humans also have the ability to excrete an equal amount of copper that they ingest daily. Table 1 shows that the electrical and thermal conductivity of copper (Cu), a member of Group 11, is superior to that of gold (Au) and second only to silver (Ag), which is why inexpensive copper (Cu) has been widely used.

[0027] This method allows for the creation of sterile gauze using a verdigris / copper (Cu) compound. This shows the values ​​when the electrical conductivity and thermal conductivity (Ag) of a metal are set to 100. TIFF2026059687000004.tif43156 Copper (Cu) was the first metal used by humankind around 8000 BC. Until the Yayoi period, Yayoi bronze bells (dotaku) were believed to possess mystical powers to ward off disease and evil spirits and were used in settlement ceremonies. The "mystery of the dotaku," which suddenly disappeared in the 10th century, coincides with the construction of the Great Buddha. It is speculated that hydrangeas (Hg), which lowers the melting point of Cu, were used in combination with firewood, and that a "great epidemic" occurred, causing panic, the Yamato regime moved the capital, and the settlements buried the dotaku.

[0028] Microorganisms such as fungi, bacteria, and viruses cannot survive on the surface of copper. Similarly, since ancient times, copper alloys have been known for their antibacterial, antifouling, and antiseptic properties, and have been used as an important metal material in aquaculture. In the Showa era, copper faucets were used in water supply systems. However, the reason why the term "copper pollution" exists in relation to vulcanized rubber dates back to the relocation of the capital, when the pollution caused by the construction of the Great Buddha of Nara (which was actually mercury) was mistaken for copper.

[0029] Copper, which breaks down the sulfurous network structure, is completely removed from the inorganic fillers used in the rubber industry and sold commercially. Since the hunting and gathering era, humans have replenished the electrical charge in their bodies by releasing Cu (copper) into the conductor Eash through sweating on the soles of their feet. Animals and plants (mammals) obtain deficient Cu / minerals from swamps in nature, and this essential element common to all mammals is... Before 1968, Japan relied on "sea salt fields," consuming copper-containing salt, but unfortunately, it now uses refined salt.

[0030] Humans and mammals have an excretory organ that automatically eliminates all excess Cu ions ingested daily, constantly fine-tuning the hydrogen ion concentration in the blood to "pH 7.4 ± 0.5" and the pH of body fluids to "pH 6.8". *The electrical conductivity of copper ions, which are essential for humankind, suggests that for microorganisms / fungi, this could be equivalent to electrocution death from high-voltage current (6000V) for humans.

[0031] Verdigris was long believed to be highly toxic, but recently it has been revealed to be less toxic. It is thought that during the Nara period, refining technology was poor, and the contamination of arsenic (As) was mistaken for verdigris.

[0032] The verdigris that forms on copper roofs / copper statues is an oxide film of copper, which has anti-corrosion and antibacterial properties, is insoluble in rainwater, and in this proposal, verdigris is an insulator (the literature states that Cu and verdigris are the same), protecting the interior from lightning strikes, disrupting the geomagnetic field of copper statues for birds, preventing droppings from damaging copper statues in various locations, and as a verdigris coating (thin film), it is expected to have applications in the fields of lightning protection paint for roofs of shrines and temples / high-rise buildings, and radio wave shielding / stealth on rooftops.

[0033] A joint study by Shimane University School of Medicine and the University of Cambridge revealed that residents of Oki Island, world-renowned for its longevity, regularly consume fresh seafood and seaweed. They have twice the amount of copper (Cu) in their white blood cells compared to Cambridge residents, and only one-sixth the number of arteriosclerosis patients, suggesting that copper intake is linked to their longevity. In recent years, it has also become clear that sudden death from myocardial infarction in turkeys can be prevented by feeding them copper compounds. In the past, people in China, Korea, and Japan also used well water to store it in brass or copper pots for their daily needs.

[0034] Modern people cannot produce essential minerals in their bodies, and in Japan, the only way to obtain them is through food, as refined salt has been replaced with one from which 14 types of minerals / bitter brine have been removed. The cultivation of vegetables in greenhouses and the farming of fish in fish pens have led to the loss of a route for obtaining copper ions, causing abnormalities in "white blood cells" essential for the nervous system and "minerals" that prevent osteoporosis. Calorie counting and sweet "sugar content" have become the national diet, and obesity due to nutrient-rich foods has led to the emergence of diabetes departments in hospitals, which are overflowing with sugar-related patients, making it a national disease.

[0035] Wild animals risk their lives to obtain minerals from nature during long journeys of thousands of kilometers. Just like humans, livestock such as chickens, pigs, cattle, and horses live on the floors of barns, isolated from the ground, genetically modified artificial feed is deficient in minerals, free-range farming has disappeared, and mass culling due to outbreaks of diseases like foot-and-mouth disease, swine fever, and avian influenza (when tens of thousands of chickens are confined to chicken coops) has become commonplace.

[0036] In the salt-rich regions along the continental coast, masks are unnecessary, and the area remains free from COVID-19, yet the horrific conditions of famine and malnutrition are still being broadcast daily. Japan, which considers itself a developed country, has a biosafety level [4] National Institute of Infectious Diseases, Murayama Branch and RIKEN Tsukuba Institute Finally, the laboratory is complete, and we can evaluate the effectiveness of this mask.

[0037] [Table 1] The proposed solution involves creating prototypes with salt concentrations of (220g / 110g / 55g / 22.5g / 10g) and testing their sterilization effects.

Claims

1. The proposed COVID-19 mask is broadly divided into an outer part and an inner part. The exterior of this design uses bamboo fiber yarn / blended yarn and features a three-dimensional structure that ensures an adult alveolar ventilation volume of 450 ml / breath (inhalation and exhalation).

The gauze mesh inner lining described above is characterized by a structure that captures and restrains all viruses that have passed through the outer lining (main body), as well as the exhaled mucosa in the patient's mouth and the humidity and mucus in the nasal cavity. The gauze mesh in this invention is, in principle, made of twisted cotton / linen yarn, and is characterized by being pre-treated with saturated saline solution and then loaded into the inner lining of the mask. The crystalline salts remaining in the twisted yarn (including blended yarn) of the interior lining are characterized by their function of stopping the life and proliferation activities of captured viruses.

3. The gauze specifications described above have 12 warp and weft threads with a diameter of 0.4 mm per centimeter, with an opening ratio of 64%. The convex sections that intersect in a square shape form a system that controls the bidirectional flow of air during breathing and the time the air remains in the air by creating four spaces above and below. The negative ion crystalline salts attract airborne positive ion aerosols, and the gauze mesh is characterized by a structure that captures and confines viruses of any type while the mask is being worn. This standard conforms to the "International Inch Standard" for medical gauze dimensions and is characterized by its application to the interior of this invention.

4. In this proposal, when gauze of the same specifications as domestic and international standards is wrapped around a 0.32 mm thick aluminum plate, the square opening is proportional to the number of layers, and the opening size of the hole is one-quarter (10 ４ The size is reduced to (10 to the power of 4), while the number of holes increases by the fourth power. The intersecting uneven parts of the laminated mesh are proportional to the fiber diameter φ, and the amount of air secured and the space remain unchanged. (Hereinafter referred to as the 1 / 2 offset structure) The standard dimensions of the laminated mesh in this invention are "7.5 cm wide x 12.5 cm long x 8 layers," and it is characterized by a form that can be housed inside the outer casing. The proposed 1 / 2 offset structure has 1.8 billion holes, while the opening size of standard-sized holes is (220 million mesh), resulting in calculated values ​​that are practically impossible to breathe. The 1 / 2 offset structure unique to this invention is actually a structure that ensures normal adult breathing.

5. The gauze raw material of this invention is sterilized in advance by boiling in a saline solution with a salt concentration of 3.4% or higher, and the moisture is evaporated to create a dried gauze mesh. The residual crystalline salts from the twisted yarn are exposed on the surface, and the principle is that its deliquescent viscosity captures / restrains viruses.

7. This proposal features a "replacement system" in which the laminated mesh of the interior lining can be replaced with a "spare" when it becomes wet from exhaled breath, allowing for repeated replacement and long-term use. The "spare" stains are removed by adding a neutral detergent and 1 gram of salt, rubbing and washing repeatedly, and the cleaning effect lasts for several years. In microwave sterilization, if mucus, bacteria, pollen, or organic matter adheres to the layered mesh, charred marks will inevitably appear around the nostrils and mouth. The burn marks on the "spare" in this proposal, no matter how small, are evidence (markers) of the elimination of bacteria, regardless of the type, and serve as a deterrent for disposal, regardless of the number of uses.
