Description

DESCRIPTION

Protection mask

TECHNICAL SECTOR

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.

This invention fits in the sector that corresponds to the current needs of life, in particular protective and hygiene garments and articles, within the sector of the industry dedicated to the manufacture of hygienic protective equipment, focusing particularly on the field of masks. facial protection.

STATE OF THE ART

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 to the outside, 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 through different elements adapts to a range of sizes to 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 user against harmful agents or pollutants in the environment that surrounds them, and which are normally used exclusively in work areas with high risk, simpler masks are also known, more widely used and in which obviously a lower level of protection is also 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, which constitutes a kind of cup that adapts to the aforementioned facial area and which is also fixed to the user's head by any appropriate means.

Filter masks [filtering-face-pieces or ffp 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 filter masks are exclusively for healthcare personnel.

On certain occasions, the user usually wears 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.

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. and FFP3 and be more comfortable for the user.

Today the masks used in the covid-19 pandemic are disposable and reusable with one or more layers and are used in hospitals, nursing homes, the workplace and the public. Filtered masks (FFP2 and FFP3) are for the exclusive use of health workers since saliva particles are emitted when inhaling. Disposable unfiltered masks become damp 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-like 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, they don't 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; Wearing 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. 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 of the environment (filters can also be made from the tissue of a surgical or hygienic mask TNT and are held in place by pressure between two concentric frames; the material of hygienic and surgical masks is TNT, a non-woven fabric made of plastic fibers dropped one on top of the other at a temperature that allows them to stick together ) at the same time, the use of biodegradable filters is supported by adapting the existing ones to the mask.

A maximum seal between face and mask is sought; the models that are 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 a minimum PPE at home and since the mask object of this application has a reusable part that is the window and also the body depending on the material (silicone, biodegradable plastic, waterproof fabric and airtight) can also be used filters for dust, mists, fumes, gases and vapors, especially in cases of emergency (such as a toxic gas leak). The therapeutic quality is achieved in the models that have a manual or automatic dispenser (ultrasound) of aromatherapy or medicines apart from the chromotherapy function.

The novelty of the invention object of this application is that it incorporates a screen-curtain (5) of filtered air that protects the user when he opens the window of the mask. It develops mechanisms so that the force of the air decreases or stops when smoking or when a soup spoon is approached. The idea arises from the need to keep pathogens out of the mask when you eat, drink, talk or smoke, reduce the chances of infection and favor the work activity of restaurants, entertainment venues, concerts, sports events, sports activities , transportation (plane, subway, taxi, buses).

The CLIU mask is considered to be the one that most closely resembles the invention. Differences: it has filters that are valid only for it, the inner 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 and could be a cause of robberies. It would be dangerous to run with the CLIU mask open as 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.

It is also considered relevant to cite the documents ES1247481U, ES1247683U, ES1247750U, ES1247826U, ES1248111U, ES1248305U, ES2352447T3, ES1247634U, ES2733337A1, ES1247687U, ES1248114U and ES1248124U.

The applicant does not know of any solution that can be considered similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a mask that incorporates a screen-curtain (5) of filtered air.

A first main embodiment of the present invention has as its object an oral-nasal mask with a work / medical / therapeutic function with a reusable structure and disposable parts (filters) that achieves the objectives of a surgical, hygienic or mask FFP1, FFP2 mask, N95 and FFP3 with or without valve (depending on the level of insulation and filtration).

It allows you to breathe normally through an opening like a window (when there is no danger of infection or intoxication) and also allows you to drink, eat and speak, which is why it is essential for restaurants and tourism, facilitating user safety due to 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.

The embodiment 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 you to eat, drink, communicate with others (you must always use it with due distance, following the safety regulations). The window can be symmetrical or asymmetric 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 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 another fixing mechanism. The mask that the invention proposes solves in a fully satisfactory way the aforementioned problems, 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). In this invention, the masks are endowed with an improvement that makes them worthy of exclusivity since nothing similar has been seen so far: breathing through the open window or windowless frames is protected by a screen-curtain (5) of air filtered out. 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.

Mask functions indoors and outdoors

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

2) Germicidal: destroys viruses, bacteria and pathogens

3) Protect

4) Avoid spreading viruses or bacteria

5) Allows confining at home with relatives

6) Use available resources

7) Facilitates the use of the mask

8) Protects the skin

9) Facilitates social interaction

10) Extends the use of hygienic and surgical masks.

The realization starts from the following elements:

1. Body of the mask, which creates a safe breathing chamber and ergonomically conforms to the user's face. It can be single-use or reusable, easy to clean because it is composed of materials that can be cleaned with simple soap and water or alcohol; non-porous materials such as rubbers and sanitary silicones or biodegradable plastics and any material that has similar characteristics and enables the desired objectives to be achieved.

Silver wire fiber sleeve or similar, which protects the filter element from impurities that could penetrate it, if it were not said encapsulated. Covers of these materials can be made to carry masks, mobiles or other elements keeping them free of viruses and bacteria.

It is reusable since they can be cleaned with simple soap and water or alcohol, except for the filter element that can be easily renewed, subtracting it from the encapsulation and replacing it with a new one. In an optional form, the mask of the invention may have a nose and mouth or full face coverage.

Exhalation valve, optional. In the event that said exhalation valves are available, this will be the preferred way for the air to exit, due to the ease and low resistance of passage that they offer.

Window, filtering or transparent. It allows drinking, eating, talking, breathing normally when there is no danger of intoxication and infection, respecting safety distances from other citizens.

Screen-curtain (5) of filtered air. The filtered air is driven by means of a propeller motor, passes through ducts that reach the upper side of the front window of the mask and is sucked in through the converging ducts on the lower side of the front window and returns to the filter forming a circuit closed. In this closed circuit, the air after being filtered can be enriched with bactericidal and antiviral substances or by ions that destroy viruses, bacteria and pathogens without being harmful to the user. You can also activate antiviral and antibacterial led screens-curtains, ultraviolet led if it is possible not to harm the skin and eyesight or electric shocks between the sides of the frame when the window is open, or between the sides of the frame if there is no window

Fan, which serves to increase the air supply and relieve suffocation; the fan will supply purified air through a filter or send air purified and disinfected outside the breathing chamber (to avoid infecting nearby people).

7. Elements of fastening to the user's face.

8. Filters, prevent harmful or toxic particles and viruses, bacteria and other pathogenic elements from affecting the user.

9. Germicidal mechanisms.

10. Therapeutic elements for the skin. For example chromotherapy, where the different wavelengths in the visible spectrum offer medical effects: Red light accelerates metabolism and the formation of collagen. Blue light has an anti-inflammatory and bactericidal effect and is calming. Green light is a great anti-inflammatory and decongestant. Yellow light achieves draining and rejuvenating results.

11. Mechanical and / or electronic elements.

The mask has disinfection means such as cold plasma at atmospheric pressure, ultraviolet (UV-C), silver wire fabrics such as SkinlifeForce (registered trademark).

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

In view of Figures 1-3, and in accordance with the numbering adopted therein, two non-limiting examples of embodiment of the reusable protective mask of the invention can be seen.

The mask that is recommended is structured from a body (1), generally with a polyhedral contour, which can also be of the bowl or hemispherical type, for example. The body (1) 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 (if possible perfect). It can also be attached to the user's head by elastic means, preferably a rubber band. For example, the elastic means can be attached by staples to the body (1).

In the body (1) a respiratory window (2) is fixed, which in the figure has been represented as a symmetrical sliding type. The window (2) can also be a hinged, folding or other type of window or without leaves (for example for a dentist's patient). The window subframe (2) supports one or more sheets (3) with a double concentric frame, made of light and adaptable material, the inner frame of the sheet (3) being snapped inside the outside, fixing some filters (4) filter sheet. These filters (4) are thus easily removable. The window frames will be biodegradable.

The filter sheet can be protected between two sheets (type sheath) of reusable disinfectant fabric type silver ions or similar (In a preferred but non-limiting embodiment, the filter fabric of the mask is made with silver threads from the Heiq HEIQ brand AGS-20 SkinlifeForce, manufactured by Nilstar). Filters can be made of various materials as long as they achieve the filtration objectives, although they do not have disinfectant effects, (The filtration tissue that is produced in quantity at these times of pandemic is type surgical or hygienic masks or TNT). At the same time biodegradable filters can be produced which will possibly be more expensive. Every user will choose the type that best suits his economy and ideals.

The opening of the window (2) can be manual or mechanical, and allows the window (2) to 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 through a cable connected to a battery (battery in the mask or carried in a container on a collar or belt).

The invention is provided with a bracelet (not shown) that opens the window, by infrared, or other electronic elements: when the hand approaches the mouth, the window (2) 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). The leaves (3) of the window (2), when opened, are introduced into sealed compartments where they are disinfected by one or more methods such as ultraviolet led, chromotherapy led with antiviral function, fabric of silver wire or copper ions, essential oils, medicines, 70 ° alcohol vapor, 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 reservoir of essential oils (tea tree, rosemary etc.) connects with the sealed compartments of the window (2) and with the breathing chamber and towards them you can spray by different means: ultrasound, mechanical / manual or electrical device or other not cited in this report. This preferred mask is reusable in terms of 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.

As an exclusive novelty, the window (2) has a screen-curtain (5) of filtered air. The filtered air is sucked in by means of a motor with propellers, and passes through upper ducts (7) that reach the upper side of the front window (2) of the mask and is aspirated through the convergent ducts (8) of the lower side of the front window (2) (other models may also include the lateral sides) and return to an internal filter (6). This system forms a closed circuit of the filtered air. In this closed circuit, the air, after being filtered, can be enriched with bactericidal and antiviral substances (essential oils) or by ions that destroy viruses, bacteria and pathogens (cold plasma disinfection) without being harmful to the user.

You can also activate curtains in the same plane or in parallel planes, antiviral and antibacterial led, ultraviolet led if it is possible not to damage the skin and sight or electric shocks between the sides of the frame when the window (2) is open. This radiation curtain can be activated between the sides of the windowless subframe (2).

Any method can be used to improve the capabilities (bactericidal, virus inactivator and pathogens) of the screen-curtain (5) of filtered air. The combinations according to aerodynamic criteria are multiple, so there are numerous possible models and their study will make available to users a comfortable, practical, effective and efficient mask that will not only help to overcome possible pandemics, if the public is responsible; it will also facilitate isolation between family members with excess occupancy in a home. The masks will always have a manual means to achieve a function to avoid problems due to electronic failures (example: manual closing and electronic closing of the window).

Its use in places that allow recharging ensures an influx of public (bars, theaters, cinemas, stadiums, airplanes, trains, public transport etc.) For example, a filter with fans can be attached, such as the XIAOMI Mi Q5S 2020 USB electric mask from Xiaomi 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 to the window (2) so that users do not touch their faces. Inside the mask has chromotherapy led lights

1

to stimulate the skin, with programming depending on the pathologies of each user, to avoid skin diseases due to lack of sun exposure.

One embodiment has a safety distance sensor that activates red light when this distance between two masks is violated.

It can be provided with a light that warns that the window (2) is not properly closed, with a microphone and loudspeaker, with an eye protector to avoid infections through this route in environments with a high viral load. Any solution that improves the model will be adapted.

The mask may have a drop down top canopy for rainy situations.
