DESCRIPTION

Filtering face mask

OBJECT OF THE INVENTION

The present invention falls within the technical sector of personal protective equipment (PPE), more specifically in relation to the facial protection of any person, to limit the risk of contagion due to germs, bacteria, viruses, small toxic particles that may be suspended in the environment. The field of application of the present invention is framed within the hygienic-sanitary sector of any field, work, educational and domestic, because it guarantees high security by offering an optimal sealing of the respiratory tract and in some models it provides a germicidal power on the inspired and expired air.

The object of the present invention is an oral-nasal mask with a disposable occupational / medical / therapeutic function or with a reusable structure and disposable parts (filters or filters / body) that achieves the objectives of a surgical, hygienic or mask FFP1 FFP2 mask and N95 and FFP3 with or without valve (depending on the level of insulation and filtration); allows you to breathe normally through an opening like a window (logically this option can be used when there is no danger of infection or intoxication) it also allows drinking, eating and talking, which is why it is essential for restaurants and tourism, facilitating user safety by the rapid closing of the window thus activating the air filtering function. It wants to be a comfortable mask to avoid continuous manipulation by the user in order to avoid infection and / or poisoning. It seeks to be respectful with the environment by using recyclable materials but in a pandemic situation (aware of the lack of personal protective equipment) it is important to use all available resources even if they are not entirely respectful with the environment (filters can be made It is also made from the tissue of a TNT surgical or hygienic mask and they are held in place by pressure between two concentric frames; at the same time the use of biodegradable filters is supported by adapting the existing ones to the mask. mask; the models that are going to be used for a long time are internally provided with LED light with chromotherapy properties in order to avoid skin problems. The COVID-19 pandemic makes us aware that it is necessary to have minimal EPIS

BACKGROUND OF THE INVENTION

Filtering face masks (also referred to in some cases as "respirators or respirators") are worn over a person's breathing passages primarily for two purposes:

(A) prevent impurities or contaminants from entering the respiratory tract of the user;

(B) protect others from being exposed to pathogens and other contaminants exhaled by the wearer. They are of different degrees of protection.

In the first situation, the respirator is used in an environment where the air contains particles harmful to the wearer, for example in an automobile body shop. In the second situation, the respirator is used in an environment where there is a risk of infection, for example in an operating room.

To achieve any of these goals, the respirator must be able to stay snugly or snug against the wearer's face. To achieve a good fit, filtering face masks generally have a headband that extends laterally from the mask around the back of the wearer's head and neck. In general, headbands include a piece of elastic strap that by means of different elements adapts to a range of sizes to

4

provide a comfortable fit.

Regardless of the different types of masks and masks, which with a substantially complex structure, protect the respiratory system of their users against harmful agents or pollutants in the environment that surrounds them, and which are normally used exclusively at the level of work areas At high risk, simpler masks are also known, more widely used and in which a lower level of protection is obviously provided.

There are masks of a textile nature, which protect the user's mouth and nose and are obviously attached to his head by different means, as well as masks obtained from a body in spongy material (example: expanded polystyrene) and in a single molded piece, that constitutes a kind of cup that adapts to the aforementioned facial area and that is also fixed to the user's head by any appropriate means.

Filter masks [filtering-face-pieces or ffp3 for its acronym in English], protect the user since they are designed to filter particles, liquid aerosols and pathogens present in the environment, preventing them from being inhaled by the user. Depending on its design, it can be: conical, horizontal (duck-beak) and vertical. Depending on the filtration efficiency, the mask is class 1, 2 or 3. The filter material is made up of a network of plastic fibers which retains the contaminant. However, it presents as a fundamental problem a rejection or misuse by a large population

Due to the covid 19 pandemic, surgical masks, hygienic masks, n95 and FFP1, FFP2, FFP3 without filter have become popular and forced in certain situations, while in general those with filter are exclusively for healthcare personnel.

On certain occasions, users usually wear the mask on the chin, on the forehead, on the elbow. In these times of the Covid 19 pandemic, it is inevitable to see how the political media, personalities, journalists and a large part of the population incorrectly and dangerously manipulate the masks they are using, creating a bad awareness of their use.

5

It will be deduced that the above is harmful since handling the masks facilitates the possibility of being infected by pathogens or contaminating with toxic substances. The user usually breathes with discomfort and with difficulty through the mask, so most of the time they abandon the protection preferring to continue without it with the consequent risk that it represents for their health and others.

The misuse of the mask is very frequent on a daily basis and all its drawbacks can be avoided by means of the invention that is now described.

In order to minimize both problems and after researching the different options offered on the internet, not having found anything similar, a new type of protective mask against harmful environments has been devised that combines the advantage of the best ffp2 masks at the same time. yffp3 and be more comfortable for the user.

For a better understanding of the present specification, a series of drawings are attached in which the mask is schematically represented in a preferred embodiment, a description of its constitution being detailed below and with reference to the same drawings.

The applicant is not aware that a protective sanitary mask exists in the current state of the art that responds to the problems described.

In this sense, the "CLIU" mask could be established as the state of the art closest to the invention, presenting the following differences:

It has filters that are only valid for it, the interior face of the window is not protected, and there are no built-in means to disinfect it before closing it, it cannot be run with the mask window open, they are very expensive (90 euros normal and the top model 250 euros could be the cause of theft. It would be dangerous to run with the cliu mask open since it would break exposing the user, it is like driving a car with a front hood that opens at the nose. It cannot be left open in different positions.

Problem to solve:

Today the masks used in the covid-19 pandemic are disposable and

6

single or multi-layer reusable and used in hospitals, nursing homes, workplaces and the public. Filtered masks (FFP2 and FFP3) are for the exclusive use of sanitary personnel since saliva particles are emitted when inhaling. Disposable unfiltered masks get wet relatively quickly from exhaled air, which makes them very uncomfortable to wear. These disposable masks are not recycled unless complex disinfection is followed. Most of these disposable masks are thrown away immediately after use, which is not advantageous from an environmental point of view, they are not biodegradable as they mostly consist of plastic fibers.

COVID-19 diseases are spread mainly from person to person through droplets that are thrown out of the nose or mouth of an infected person when coughing, sneezing or talking. These droplets are relatively heavy, do not go very far, and fall quickly to the ground. A person can get COVID-19 if they breathe in droplets from a person infected with the virus. That is why it is important to stay at least two meters away from others. These droplets can land on objects and surfaces around the person, such as tables, knobs, and railings, so other people can become infected if they touch those objects or surfaces and then touch their eyes, nose, or mouth. For this reason, it is important to wash your hands frequently with soap and water or an alcohol-based disinfectant; Using a mask is already mandatory in all of Spain, it must be worn in all closed public spaces and also in open ones, with few exceptions; it is important to maintain an interpersonal distance of almost two meters.

We are exhausted and it is easy to see people use the mask incorrectly, due to fatigue, ignorance, recklessness, manipulating them, removing them when speaking, coughing, sneezing in public, wearing the mask hanging on the neck, raised their forehead, without completely covering their mouth and nose, wearing it as a bracelet on the elbow or wrist. It is very difficult not to spread the virus if you come into contact with it.

EXPLANATION OF THE INVENTION

The invention allows the combination of filters and valves, in order to be able to adapt to the greatest number of users and situations, so that breathing can be adapted to the patient / user. Likewise, having a window allows eating, drinking,

7

Communicate with others (always use with due distance following safety regulations). The window can be symmetrical or asymmetrical and can have one or more leaves where filters are fixed by pressure. In the reusable version with a surgical or hygienic mask filter or other fabrics (recyclable after disinfection by different approved means - TNT fabric or silver ion thread) it allows to reduce the use of hygienic or surgical tissue by at least half, with the consequent savings, helping to prevent or reduce shortages in the event of a pandemic. The window opening mechanism can be manual or mechanical. The mechanical opening is activated by means of electronic elements (sensors or infrared) that are placed in a wrist strap, so the window opens when we bring our hands to our face to eat after activating the function. (A very simple means is a pneumatic circuit with a small pressure pump in the mask combined with magnets). In fabric or other fabric masks, the window closure can be by velcro, or by pressure or other fixing mechanism. The mask that the invention proposes solves in a fully satisfactory way the aforementioned problem, offering structural characteristics that allow for it a clear reusable / disposable character, being important in schools, universities, airplanes, buses; cars, theaters, leisure, restaurants. (In addition to work and health).

Having made the preceding description, we must add that the details of the realization of the exposed idea may vary, without thereby changing the essence of the invention. The masks that adapt the surgical and the hygienic ones would have to be mandatory since whoever does the test with a glass and covers it with a mask and makes water will observe that an area appears where the water filters and falls into the glass; It corresponds to the areas of contact with the skin (especially the nose), the rest is usually intact, it does not filter water even if it has been taken several days. This means that we are underusing the potential of surgical and hygienic masks and if we rectify we will avoid many positives in infections (since the area that filters water filters viruses and bacteria) and we will achieve a better ecological balance and considerable savings.

Functions of the mask indoors and outdoors:

1) Filtering: prevents harmful or toxic particles and viruses, bacteria and other pathogens from affecting the user.

Disinfection methods:

COLD PLASMA DISINFECTION:

Advantages of disinfection with atmospheric pressure cold air plasmas

The exceptional disinfection properties of plasmas are well known and documented. Atmospheric pressure plasmas, and especially piezoelectric direct discharge plasma, have shown strong disinfection ability. Compared to standard disinfection and sterilization methods using 170 ° C pressurized hot air, 120 ° C pressurized hot steam, wet chemistry, or low pressure plasmas, cold atmospheric pressure air plasmas offer the following advantage:

• Atmospheric pressure treatment allows disinfection of objects that can be damaged by vacuum or overpressure

• No expensive pressurized or vacuum chambers and pumps

10

• No wet chemistry

• Deep cleaning, no residue

• Low operating temperature

• Gentle treatment of sensitive surfaces, including living tissue and open wounds

• Inexpensive non-toxic air or working gases

• Respect for the environment

Ultraviolet: UVC, ultraviolet light. It destroys the DNA of microorganisms and they are inactivated. The skin cannot be exposed to UVC so it needs to be encapsulated with a strict and special measure. Example: the air passes through a capsule where UVC deactivates viruses and bacteria.

Disinfection by weaving silver thread (SkinlifeForce, the special thread that neutralizes viruses and bacteria; threads whose composition comprises silver ions that cause an active principle that neutralizes viruses and bacteria); not intended for surgical use, washable at 60 ° - 65 ° C, with a comfortable fit and great breathability; Product reusable up to 100 times, it is a technical fabric with an active principle that neutralizes viruses and bacteria thanks to the composition of silver ions in the thread with which it is manufactured.

Chromotherapy-led. Chromotherapy makes use of the colors belonging to the visible spectrum, that is, using the specific energy that each wavelength possesses. In a simple way, we can say that each color that we perceive emits a certain energy, this is classified using a value corresponding to its wavelength, which, as is known, is the time interval between two consecutive maxima of some physical property of the wave, or the distance between its two peaks. The energy range, with which we work, goes from 380 nm, to approximately 750 nm, of wavelength, the first ones belong to violet, and the last ones to red.

1. Red light: this light reaches a great depth in the skin, reaching 660nm. Thus, it accelerates metabolism and improves collagen formation. All this favors the whitening of the skin and an increase in its elasticity, helping to reduce wrinkles and making it a truly effective anti-aging treatment.

eleven

2. Blue light: blue light is really beneficial in aesthetics thanks to its anti-inflammatory and bactericidal effect. For this reason, facial chromotherapy with blue light favors the elimination of acne and a recovery of the skin, given its calming power. In addition, this type of light reaches 415 nm.

3. Green light: this type of light is quite similar to blue light, so it is also quite suitable for removing blackheads and acne treatments, reaching 518 nm. But, in addition, it is a great anti-inflammatory and decongestant. Thus, chromotherapy with green light provides great benefits for the depigmentation of skin with spots and for skin damaged by age or the sun.

4. Yellow light: another of the most applied lights in aesthetics is yellow light. This variety of light goes deep into 590nm and achieves draining and rejuvenating results. Among its aesthetic benefits are its power to illuminate and unify skin tone, reduce blemishes and hide wrinkles.

Benefits for the skin:

1. Relaxation: facial chromotherapy helps reduce facial stiffness thanks to the therapeutic effect of color on our body.

2. Detoxification: it achieves a bactericidal and cleansing effect on the body that make chromotherapy the ideal treatment for reducing spots, reducing acne and rosacea.

3. Biostimulation: this benefit of facial color therapy with LED light is what makes our skin look revitalized, rejuvenated and nourished. All this thanks to its cell renewal power and its anti-wrinkle power.

Disinfection:

• Aromatherapy .: essential oils with antiviral, antibacterial and anti-mold properties

• Electricity. Tissues or materials through which current circulates that destroys pathogens

• Alcohol

• Soap.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, and especially of figure 3, and in accordance with the numbering adopted therein, an example of a non-limiting embodiment of the reusable protective mask of the invention can be seen.

The mask that is recommended is structured from a body (7) in general with a polyhedral type contour (in other models it could be cup or hemispherical type). In said body or skeleton, the frame (2) of a respiratory window (3) is fixed. The leaf (4) of the window will be equipped with a filtering material (14), and can be symmetrical sliding, (other models may have a hinged, folding or other type of window) it is completed with a leaf per side with a double concentric frame, fitting the smallest within the largest among which are fixed pressure filters so that their replacement is easy. The window frame is fixed by removable connection to the pre-frame of the mask body. The body of the mask is fixed by pressure between the window frame and pre-frame. Between the face and the body of the mask there is a ring attached to the body that surrounds the entire face (5,6) (see figure 4), from the right side of the nose, going down the right cheek, crossing the chin going up the left cheek and reaching the left side of the nose. This ring comprises a filter material and fits perfectly with the body of the mask and the

fifteen

everything is attached to the face completely covering the mouth and nose and remaining completely adhered to the skin and stabilized by the pressure exerted by one or more elastic cords that surround the head or ears, obtaining an optimal seal (perfect if possible); It is attached to the user's head by elastic means, preferably a rubber band. The ring is created so that it can admit self-disinfectant and / or washable filter fabric such as TNT or Fabric with silver ions (In a preferred but not limiting embodiment, the filter fabric of the mask is made with silver threads of the brand Heiq HEIQ AGS-20 SkinlifeForce, manufactured by Nilstar). The ring can also accept other types of filters as long as they achieve the filtration objectives although it does not have disinfecting effects. The ring is designed so that it can contain filtration tissue that is produced in quantity at these times of pandemic (such as surgical or hygienic masks or TNT.) Forming a mechanism for this purpose. The ring is made up of the upper half-ring and the lower half-ring, they are articulated with a right and a left bolt (9) on both sides of the jaw, facilitating the movement of the latter without impairing the sealing of the face. This example of a ring is not limiting and any solution that improves it will be adapted.

As can be seen in figure 2, when the window leaves (4) are sliding, when they are opened they enter compartments (1) where they are disinfected by different means.

For their part, the window panes can be stabilized by magnets (15), as shown in Figures 5 and 6, without ruling out other means.

According to figure 14, the mask can have an asymmetric folding window, being linked through a conduit (11) to a filter (12) and a manual pneumatic element (13) to facilitate breathing.

Figure 15 shows a mask conveniently adapted to the face of the user for running, it tilts by pivoting on a horizontal axis, leaving an opening to breathe better when there are no people. It opens as a folding window articulating the leaves on a longitudinal axis.

According to Figures 16 and 17, the mask can be opened along its longitudinal axis or along its transverse or horizontal axis.

16

At the same time, and as shown in figure 21, the mask can incorporate protective glasses (18) or transparent screen, as well as a perimeter anti-pathogen filter in said area of confluence with the user's face.

In a variant embodiment, the one shown in figure 22, the main body (7 ') of the mask can be obtained in a grid, on which the corresponding single-use or multi-use envelope is implanted.

In another variant of embodiment, the one shown in figure 23, the mask will be made of an impermeable material, so that the window (4 ') is established in a lower horizontal plane or in an area in which the lower edges of the mask body are below the bottom plane of the window edge.

At the same time, biodegradable filters will be produced that will possibly be more expensive.

Each user will choose the type that best suits their economy and ideals.

Staples or adjustable connecting elements act as links between the body of the mask and the ends of an elastic cord or face-fixing element (10) .Each window pane is made up of at least two concentric frames of a lightweight and adaptable material, such as polyethylene (preferably biodegradable) that fit the smallest within the largest; between them by pressure a filter sheet of the most suitable material for each type of use is retained, and that can be easily and quickly renewed. The filter sheet can be protected between two sheets (type cover) of reusable disinfectant fabric type silver ions or similar. The window opening can be manual or mechanical. The window can be left open in different positions. A small electric motor with pulleys or mechanisms activated by pneumatic elements can be used for this purpose. Mechanics can also comprise electromagnets; the latter are more recommended because they can be sealed by plastic or silicone or other products that offer similar characteristics. The electromagnets are activated by the charge that circulates by cable connected to a battery (this is carried in a container that hangs from a necklace or belt).

The invention is provided with a bracelet that opens the window by infrared or other elements

17

electronic: when approaching the hand to the mouth the window opens and when moving away it closes. The bracelet has other buttons that facilitate other functions: in particular to keep the window open when we speak (in particular there may be a sensor system that activates the window opening when we speak and closes it when we are silent). When the sliding window leaves are opened, they are introduced into sealed compartments where they are disinfected by one or more methods such as ultraviolet led, chromotherapy led with antiviral function, silver or copper wire fabric, essential oils, medicines, alcohol vapor 70 °, electricity or others not nominated. In the mask there are small deposits for 70 ° alcohol and / or essential oils (one or two cubic centimeters since not much is needed in very small spaces).

The tank of essential oils (tea tree, rosemary etc.) connects with the sealed compartments of the window and with the breathing chamber and towards them you can spray by different means: ultrasound, mechanical / manual or electrical device or other not mentioned in this memory. This preferred mask is reusable in terms of the ring, body, window, electronic and mechanical elements and is provided with filters for one or more uses. Filters are thrown away after their usage time has expired. The description thereof is made with the help of the attached drawings, which show a perspective of the mask and a detail of its placement to cover the user's mouth and nose. Filters are thrown away after use.

A filter can be coupled with fans such as the USBXIAOMIMi Q5S 2020 Xiaomi electric mask but with germicidal adaptation. Contains anti-run over led security lights. It accepts as filter the tissue of surgical mask, hygienic mask, those of FFP2 and FFP3, and any other material that is used to produce filters and TNT.

A grille can be attached so that users do not touch their faces, as shown in figure 18.

Inside the mask there are led chromotherapy lights to stimulate the skin (with programming depending on the pathologies of each user) to avoid skin diseases due to lack of exposure to the sun. It has a safety distance sensor that activates red light when it is breached (it is in the same models). His name: Distance meter. It is provided with a light that warns that the window is not properly closed, Microphone and speaker,

18

Eye protection to avoid infections through this route in environments with a high viral load.
