    [0002] PORTABLE DEVICE FOR PROTECTION AGAINST AEROSOLS AND DISINFECTION OF FILTERS
    [0004] TECHNICAL SECTOR
    [0005] The present invention is comprised within personal protection devices, more specifically, against infections by viruses in aerosols, and by particles, microorganisms or toxic, harmful or polluting elements in the air.
    [0007] BACKGROUND OF THE INVENTION
    [0008] The health authorities recommend protecting the respiratory tract and eyes, when there are risks of contagion by aerosols, as well as to protect the respiratory tract against harmful elements or pollutants toxic or harmful to health, in the same way eye protection against elements that can cause damage or contagion of diseases.
    [0009] Following safety recommendations, protective elements such as masks, face shields and goggles are usually used, among other types of face protections most used in laboratories and by professional personnel, such as domes, helmets and diving suits. All these protections are aimed at preventing elements or particles harmful to health from coming into contact with the user's respiratory tract and eyes.
    [0010] The use of masks in the case of pandemics is usually mandatory or recommended, both in outdoor places and especially in closed places or places, where there is a greater possibility of contagion due to lack of ventilation, as well as health professionals in addition to using masks , wear goggles or face shields to protect the eye area.
    [0011] An individual infected by a virus, can infect other people, through the expulsions of nasal or oral secretion, in the form of drops of fluids of different sizes, these secretions can be produced in different ways, when the infected person sneezes, coughs , or simply through the action of speaking among others.
    [0012] This is why health authorities among the most important recommendations to avoid contagion and prevent the spread of viruses, recommend that there be a safety distance between people of several meters, to try to prevent a person infected by a certain virus from reaching a healthy person in their secretions and thus prevent the spread and viral infection between people.
    [0013] This safety distance between people is very difficult to maintain, mainly in indoor areas or closed places where space is limited or reduced, such as in offices, industrial warehouses, indoor work areas, transport, schools, universities, etc. hotels, restaurants, bars, nightclubs, theaters, gyms, shops, supermarkets and practically anywhere indoors. In turn, the safety distance between individuals is also difficult to maintain in open places that are attended by many people, and also the social customs established in most cultures and countries, make the safety distance not be maintained. in social gatherings or family gatherings. This lack of rigor in the fulfillment of keeping the distance between people, is a high risk factor that finally usually ends with a notable increase in the spread of a virus.
    [0014] The safety distance between people in some cases is impossible to maintain, as in the case of health professionals, in these cases the professionals not only cannot maintain the safety distance, but on the contrary they must be close or in direct contact with the patient, so the use of masks and glasses is the only thing that protects them against possible contagion or contact with a virus. Protective masks should be as effective as possible and should be self-filtering and as watertight as possible, but in most cases, both among professionals and the general population, the so-called "Surgical" or "FPP", none of these masks are completely tight in their contour, so if a patient, for example, sneezes or coughs directly on top of the healthcare professional, the mask could not avoid stopping the entire viral load, not being able to prevent The viruses will be able to enter through the gaps around the mask or glasses and thus reach the respiratory or ocular tracts, causing contagion. Therefore, the typical masks mostly used by the population, serve to reduce the expulsion of oral or nasal secretions of infected individuals, but they do not manage to avoid the approach or the physical impact of the viruses against the surface of the masks, glasses or facial screens. , leaving these elements contaminated after contact with viruses, not being able to protect a healthy user from possible infections, therefore, the health authorities they place special emphasis on the population maintaining a safe distance of several meters between people, thus trying to prevent viruses from reaching and impacting the face of healthy people.
    [0015] The problem of the spread of viruses, as in the case of Covid19, is even more serious, since according to the latest scientific studies the SarsCov2 virus, responsible for Covid19, can be transmitted by air, in fact as indicated in different studies, this is the main mode of contagion, transmission by aerosols.
    [0016] This peculiarity of this virus changes the established rules, since the latest scientific studies have shown that the virus is not only transmitted by droplets of greater or lesser size that an infected person can release or release through oral or nasal secretions, but also It is more than likely that most people are infected by inhaling the virus that circulates in tiny particles that are suspended in the air in the form of aerosols.
    [0017] These particles suspended in the air can be inhaled by other people, and the most worrying thing is that they can remain suspended in the environment for hours and travel distances beyond the two meters established as a safe distance between people. Above all and especially in indoor places that do not have good ventilation, the risk of viruses in suspension floating in the air in the form of aerosols increases the risk of contagion.
    [0018] The World Health Organization (WHO) has recognized the existence of this airway of contagion by aerosols, in turn groups of scientists from different countries, have carried out studies in which the spread of viruses is indicated as the main route of infection by aerosols. In this case, the safety distance of two meters would not be enough, since as has been explained the distance that a virus can travel is greater, reaching, according to scientific studies, even more than eight meters away, or remaining for hours in suspension in the environment. The inhalation by a healthy individual of contagious microscopic particles in the form of aerosols, which remain suspended in the air for hours, after leaving the nose or mouth of an infected person, may be the main route of infection according to the latest studies. Likewise, the time that these contagious microscopic particles remain in suspension floating in the air, with the risk of accumulating and infecting someone, depends mainly on the ventilation factor. In this sense, specialists recommend avoiding activities in closed places, and the need to direct outside activities that are possible, since it has been observed that contagion is less likely in adequately ventilated places without allowing viruses to accumulate in the environments. In the case of transmission by aerosols, the protections normally used by the population such as surgical masks and other models of masks and the maintenance of a safety distance of two meters, are not enough to protect against viruses carried by air, or that are in suspension.
    [0019] In the same way, in another sense of protection, allergic elements such as pollen particles or mites can be found in the air, different types of microorganisms, germs or bacteria can also be found in the air, especially in hospitals or closed places, and Likewise, the air may contain pollutants such as fumes, liquids or gases, which can penetrate into most of the most commonly used masks or goggles through gaps, wrinkles, lack of fit or through penetration of the fabric or material with which are manufactured.
    [0020] In the event that the protection elements come into contact with viruses either by direct reach through sneezing or coughing from an infected person, or by means of contact through aerosols directly on the surface of a mask, screen or glasses , will make it necessary to clean the protective piece or, in the case of the masks, for them to be replaced by a new one, since through contact with a virus, said protective pieces are contaminated, because viruses can stay active for hours on most surfaces. These protection elements act as physical barriers to stop the viruses when there is contact, but are dirty or contaminated when there has been physical contact with the viruses themselves. Another problem that society faces in the face of the spread of diseases transmitted by air or aerosols, is the discomfort suffered by the users of the masks, people who are forced to wear masks for long periods of time, tend to suffer discomfort when breathing, since many times an overexertion must be made in inspiration, which makes many users remove or lower the mask for a moment to achieve more easily inspire, this makes that during that period of time in which the mask is lowered or removed from the nose or mouth area, the individual is unprotected against possible contagion, in fact it is common to see people with their nose outside the mask to avoid the feeling of overwhelm. This feeling of overwhelm is especially produced by the exhalation of the For the user, the exhaled air carries with it carbon dioxide, in addition to generating steam and heat, which makes the inside of the mask maintain a higher temperature and the sensation of lack of air is greater.
    [0021] This vapor that is generated by the use of the mask that is condensed inside, makes a user's glasses foggy with the vapor of the exhaled air, this condensed air escapes through the fabric, or through the upper part of the the mask and rises to the glasses causing fogging, the user having to manipulate the glasses to clean them or lower the mask to favor the entry of air.
    [0022] These problems of feeling overwhelmed, shortness of breath, heat and fogging of the eye protection, are undoubtedly problems for the general population, but they are even more so for health professionals who must remain throughout the working day with the elements of protection placed in closed places such as hospitals.
    [0023] Therefore, respiratory protection masks can cause problems of difficulty in breathing in people with respiratory problems, such as asthmatics or other respiratory problems, in severe cases of this type of disease, medical professionals may advise against the use of masks for these people, remaining unprotected against airborne infections or being able to easily infect others in the case of being infected.
    [0024] Another problem of fundamental importance when it comes to controlling the spread of viruses, is that which occurs when drinking or eating. As is known, health authorities have substantially reduced capacity in catering establishments such as dining rooms, bars or restaurants. In these places the risk is greater, since in order to drink or eat, an individual must remove the mask, being at those times exposed to possible contagion or exposing third parties to be infected on their part, in the case that it is positive to a contagious airborne disease such as Covid19. It is even more risky in the case of eating inside bars or restaurants, since this risk is increased by lack of ventilation or drafts, which can lead to viruses being suspended in the air for hours and since the diners are not protected in any way since they cannot wear the mask while they perform the act of eating or drinking, it makes this situation dangerous due to the transmission of viruses in aerosol form.
    [0025] For all these reasons, it is necessary to develop a device that increases security against the spread of diseases by airborne transmission, such as the transmission of viruses in the form of aerosols, even if it is not possible to wear a mask or glasses.
    [0026] A device that prevents direct contact of viruses against the facial area and that can prevent direct contact of viruses with the surfaces of the protections, such as masks or goggles, which acts in this sense as a protective barrier, that prevents surfaces from being contaminated by contact.
    [0027] That it can protect people even when they are not wearing masks or protective glasses, as in the case of when these people are eating, drinking or doing sports.
    [0028] An advanced device, which protects people even if the safety distance cannot be maintained, for example, in medical consultations and hospitals, on public transport, on flights or trains, in work activities such as meetings or family gatherings, in schools and universities, in sporting events, among many other activities.
    [0029] Device that increases protection both outdoors and in closed places, that protects the facial and eye area from the approach of viruses, through the continuous generation of upward filtered air currents, which form an invisible physical barrier, which prevent the approach of external elements the user, even when the respiratory protection mask cannot be used.
    [0030] A device that eliminates the sensation of shortness of breath, that helps to eliminate the heat and steam produced by exhalation and therefore that avoids the fogging of glasses, especially for people with prescription glasses or for healthcare professionals in whom the Fogging of glasses can cause serious problems.
    [0031] And in the same way as the device, it can protect users from other elements that are in the air harmful to health, such as pollen, dust, mites, bacteria, germs, smoke, gases and other elements that are transported by air or by aerosols.
    [0032] As well as the device itself that generates filtered air currents, carry out self-cleaning and disinfect the air filters, by means of portable ultraviolet light generators.
    [0033] In short, it is necessary to create a device that, in a portable way, can exponentially increase safety against aerosol infections among other harmful elements transported by air. That complements the safety elements such as respiratory protection masks and eye protection and that can even protect people from the approach of viruses to the respiratory and ocular tracts whether or not they are wearing masks or glasses, even when the distance cannot be maintained. security against contagions.
    [0034] A device that generates aeration, ventilation and drafts by itself in the form of personal protection. A device that can protect users even during lunch or dinner, where the mask cannot be placed and where it is difficult to maintain a safe distance from other diners, especially that is effective indoors where there is a greater risk of contagion. Likewise, it allows health professionals to increase protection against the approach of particles or viruses, avoid that viruses come into contact with the protective elements PPE such as masks or glasses and even avoid the approach of viruses to the skin and the hair, a device that alleviates the sensation of lack of air and reduces the temperature that is generated with the use of masks and PPE equipment, in long periods of workday, as for example in the case of health professionals.
    [0035] Similarly, it should be a device that protects athletes, who are not able to use a mask during physical activity, due to lack of oxygen or respiratory overstrain they have to perform, which leads to less physical performance. , which can be of special relevance among elite or professional athletes.
    [0037] EXPLANATION OF THE INVENTION
    [0038] The main advantages provided by the present invention make it a portable protection device against contagion by aerosols, which offers greater safety to the user in addition to the basic protection elements such as masks and glasses and even that this device have the ability to protect, even without the use of masks and glasses.
    [0039] The device against aerosols of the invention has one or more electronic devices that generate upward ventilation, achieving facial and eye protection, as well as a HEPA air filter system (from the English "High Efficiency Particle Arresting", or " picker high efficiency particulate "), which have the ability to stop most harmful particles, including viruses as in the case of SARS Cov2 among others, in addition to other irritating allergens or harmful elements that are in the air, generating filtered and clean air currents preferably upwards, creating a frontal barrier against the user and avoiding the approach of particles , harmful elements or viruses to the wearer of the device, thus protecting both the respiratory tract and the eye area and in turn preventing viruses, for example, from coming into contact with the surface of the mask, glasses or skin of the wearer of the device .
    [0040] An advanced and portable device, against the contagion caused by viruses in aerosols, that has the ability to self-clean and disinfect air filters, which has an electronic system of portable ultraviolet light generators with among other disinfection effects, germicidal, bactericidal and virucidal effect, with which the useful life of air filters would be exponentially extended. The device of the invention is characterized by integrating one or more internal or external fans in the device, which generate a continuous current of ascending air, using the external air and filtering it, throwing it upwards and not allowing the approach and impact of virus against the face. The air current generator (s) are positioned in the supports designed to house said electronic devices, supports that also house the air filters and the ultraviolet light generators in the body of the device, once placed or placed in their place, by pressure, thread, or by any type of fixing, these fans generate a continuous stream of air with an upward direction, which directs the air stream from the lower part of the wearer's neck or chin to the upper part of the head, said current Continuous air acts as an invisible facial contour barrier, to prevent the approach of microorganisms, viruses or harmful elements and particles to the user of the device, causing them to be pushed upwards, out of reach of the entire facial area, the user's airways and eyes.
    [0041] Taking advantage of the microscopic size of the microorganisms or as in the case of viruses, any particle exhaled by an infected person or any microorganism or virus that is floating in the air as an aerosol, will be expelled by the air current generated by him or the device's fans, an effective way to maintain a clean, ventilated atmosphere free of particles and viruses, in front of the user, by the continuous generation of frontal and upward air currents, these air currents not only act as a barrier stopping and expelling the viruses by contact with the generated air stream, but also the stream of filtered air continuously generated by the fans, prevent the virus from coming into contact with the mask, glasses, eyes or the face of the user, eliminating contact risks and preventing surfaces from being contaminated, since the generated air current expels viruses before contact occurs, preventing viruses or particles from passing through the air current.
    [0042] Said air-generating electronic device can be easily and comfortably carried by the user, preferably and not limited to the shape of a necklace or pendant, so that it is positioned in the lower area of the head, chin or neck and thus directs the air. ascendingly protecting the entire facial and eye area of the wearer of the device. Likewise, the housing of the device contains fixing pieces, which prevent sliding or movement once in place, said fixing pieces, can be clips to hold the wearer's clothes or magnets, among others, such as adherent silicone pieces. The present invention has fixing elements, to close the open ends of the device and achieve a frontal and surrounding arch of filtered air to protect the entire face including the lateral parts of the head.
    [0043] Portable device characterized by integrating at least one electronic ventilation system that introduces the air from the outside, once this air has passed through the air filters and directs that clean air or directly upwards directly through the air filter (s). external fans, or by means of the internal fan (s) and the different air outlet nozzles available and can be directed to the desired angle, generating one or more updrafts of clean air, creating a continuous safety barrier.
    [0044] It is a device that helps reduce the sensation of lack of air or overwhelmed by the use of masks, since the clean air currents generate a cooler atmosphere, alleviating the sensation of heat produced by breathing and even avoiding the fogging of glasses.
    [0045] The device has at least one fan to introduce air inside the device housing and expel it to the outside directly directing the blown air to the desired area, the device that acts as a blower, generates a continuous intake of filtered air and also a continuous outlet of filtered air to the desired area. These small ventilation systems are silent devices, to avoid noise in operating mode.
    [0046] Being this air filtered by means of high efficiency filters, which ensures clean air at the inlet and outlet, which prevents the user of the device itself from being infected by the circulation of dirty or contaminated air in the face protection area.
    [0047] The invention is characterized by integrating portable electronic systems that generate ultraviolet light, through the use of UVA or UVC-LED lamps, preferably and due to their tiny size, through the use of diodes called UVC-LED, for disinfection equipment, with the nanometers required for a germicidal action, and they are positioned in the supports designed to house said electronic devices in the body of the device, once they have been placed or are in place, by pressure, thread, or by any type of fixation. These ultraviolet light generators are integrated into the device, preferably in the same place where the air inlet area is located, where the filters are integrated, in this way they are superimposed, remaining one on top of the other, being able to carry out auto- disinfection of air filters. These ultraviolet lights, called germicides, are effective in the rapid disinfection and elimination of microorganisms such as viruses, germs and bacteria, among others, by exposure of ultraviolet light on surfaces, liquids and air. Said ultraviolet light generator system is arranged and designed in such a way that it cannot direct the light towards the skin or eyes of the user of the device, avoiding the exposure to the user of light, by means of an opaque protection piece in its contour, which only allows the emission of light to the internal part of the system, that is, directly to the air filters, having a reduced light beam power and limited to the necessary distance where it must act.
    [0048] The electronic devices that make up the device are small for integration and weight reduction, all of them have on and off buttons and different power selections, so that the user can activate or deactivate them when necessary or when want, all of them with built-in rechargeable batteries, which allow their use without having to be connected to any electrical network during use and you can use, for example and without limitation, a rechargeable mini USB line, as another possibility of power source, the device can have a solar battery, with solar charging plates in the device housing. In the case of the use of solar batteries, regardless of whether they include conventional recharging batteries, it would allow the battery to be recharged automatically through the action of solar energy, especially outdoors, increasing the capacity of use and for example leaving the conventional battery as a reserve.
    [0049] The incorporation of solar batteries makes the device more ecological, also by incorporating electronic ultraviolet disinfection systems, the duration of the filters is considerably increased, reducing the generation of filter waste in the environment and using materials for the manufacture of the housing. recyclable.
    [0050] These electronic devices can be removed for cleaning or disinfection of the housing that supports them, independently of the electronic devices. Anti-aerosol protection device, removable in its entirety, to facilitate individual cleaning. Manufactured in materials that allow washing with disinfection products, waterproof and submersible, resistant to high temperatures for disinfection by heat and equally resistant to other disinfection treatments or exposure to ultraviolet rays among others.
    [0051] Preferably the housing of the device is made of hypoallergenic material for contact with the skin, preferably soft and flexible materials to increase user comfort. Likewise, the material can include in its composition, materials that increase safety, that is, materials called antibacterial, antimicrobial and / or fungicidal, which increases the self-disinfection of the surface of the device itself, this effect is achieved for example and non-limiting, by incorporating antibacterial or antimicrobial additives into the manufacturing material, such as silver or copper particles and elements, capable of deactivating or reducing viruses, as in the case of SARS Cov-2, forming these Particles are part of the material from which said casing is made, making it even safer when carrying or handling them and preventing viruses from remaining on said surface, reducing the viral load on it.
    [0052] The device of the present invention can be managed and controlled all its functions without having to take it off, both manually by means of operating buttons, or by hands-free, with a wireless connection through an electronic module called "Bluetooth" or similarly, for the control of functions incorporated inside the casing, which allows the operation, handling and connection of the device from and with other electronic devices, for example from a mobile phone.
    [0053] The technical characteristics of this anti-aerosol device form a technical effect that interacts by generating a filtered ventilation stream for hours, against the particles that approach the user. Making this a respiratory, eye and facial protection device, by means of the continuous generation of filtered air stream, to avoid contagion by aerosols and the approach of particles or harmful elements.
    [0054] The World Health Organization has established a minimum safety distance between people of two meters to prevent viruses from contacting individuals, this anti-aerosol device prevents viruses from contacting the respiratory tract, facial and eye area of the wearer of the device even if it is not possible to maintain the safety distance. Likewise, the WHO and health authorities have advised that closed places should be as ventilated as possible with air currents, so that viruses do not remain in suspension, so this device also ventilates individually and by itself. closed spaces and avoids the formation of stagnant air where viruses can remain in suspension, being highly recommended in closed spaces or with little ventilation. As an example, if in a school classroom, all the girls and boys were wearing these anti-aerosol devices and activated, the upward ventilation generated by each of them, multiplied by the number of users, would be enough to ventilate a classroom. and avoid the stagnation of viruses in the environment during school activities. At the same time, the device would be a more comfortable and safe way to protect minors who can hardly bear correctly placed masks for a long time. Users would be duly protected with continuous ventilation, generating currents of filtered air that act as an air barrier during the ignition mode, when ventilation is necessary, not allowing the virus to get close to the facial area and eyes, especially in public spaces, or such as airplanes, trains or public transport in general, in restaurants, bars, work and family meetings, as well as in many other places, in which the safety distance is difficult to maintain, minimizing the risk to the exposure, increasing and generating air currents and ventilation. Likewise, the device that generates air currents could protect athletes, who due to their physical activity and respiratory overstrain needs, cannot carry out the activity with protective masks, which would generate a lack of oxygen, a feeling of fatigue and force to an envelope respiratory effort on the part of the athlete, their physical performance and even their health may be affected. The device that generates anti-aerosol currents would allow the athlete to be protected in a comfortable way, without the need to use a mask and avoiding the approach of viruses to the frontal and surrounding area of the rotator, in addition to cooling and relieving the sensation of heat.
    [0056] BRIEF DESCRIPTION OF THE DRAWINGS
    [0057] A series of drawings that help to better understand the present invention and that are expressly related to an embodiment of said invention that is presented as a non-limiting example of this will be described below very briefly:
    [0058] Figure 1 shows an example of the portable device of the invention, placed in the body and seen from the front, the housing of the device 1, in a closed position by means of the locking pieces preferably magnets 6 to achieve a perfect fit and to form a closed front arc and surrounding the user's face. In the upper area of the device, there are mobile nozzles 2 air outlets, which allow directing the air. Likewise, the holes or couplers 4 are shown, where the portable and security electronic devices are located, such as the fans, the ultraviolet light generators and the air filters 10. On the front of the device, the buttons are shown. on, off, selection of fan speeds and operation indicators 5, indicators with built-in light, so that people can observe that the device is in operation or not and take the pertinent safety measures. Also on both sides are the operating buttons for the ultraviolet light generators 12. On one of the sides is the battery charging port 7, preferably a mini USB charging port.
    [0060] Figure 2 shows an aerial view of the device of the invention, with the casing 1, where the air outlet nozzles 2 are located in its upper part. Likewise, the protection for the back of the neck 3 is observed, which preferably cushions and makes the use of the device more comfortable, as well as being a non-slip, hypoallergenic and soft material for the skin. On both sides you can see the holes 4 where the electronic and safety elements are inserted and positioned, internal current generator fan 8a, ultraviolet light generator 9, which is made up of ultraviolet light LED lamps or diodes germicidal, to carry out the disinfection of the filters and the air, and preferably the high-efficiency air filters called HEPA 10. On both sides of the housing 1, there are the angle and length regulation joints 11, to achieve a perfect fit and adapt to the size and neck circumference of the user. Also on each side of the casing 1, there are the ultraviolet light operation control buttons 12, to turn on and self-disinfect the air filters. On one of the sides, there is the battery charging port 7. And on the front of the device, the locking pieces preferably magnets 6 and the buttons and air operation indicators 5.
    [0062] Figure 3 shows a profile view in which the user is using the device in closed mode by the magnets 6, the device is in operation with the indicators on 5, therefore the internal fan is introducing air from outside into inside the casing 1, outside air through the hole where the air filter 10 is located, so the filtered air that is introduced is clean air, and this is blown upwards, leaving through the nozzles 2, which can be directed to direct the air correctly, in a representation by lines with arrows, it can be seen that the direction of the air is upward and surrounding the facial and ocular area of the user, also protecting the frontal area of the face.
    [0063] In this recreation of operation, it can be seen that the user does not wear a respiratory protection mask, as in the case of being in a restaurant without being able to put on the mask to eat, but still has a protective barrier of clean and filtered air. that pushes and prevents microscopic viruses from crossing the air barrier. It is essential that the air is previously filtered by the filters 10, since if it is not filtered air, the use of ventilation of contaminated air to the face of the user would be counterproductive and this dirty air could infect him.
    [0065] Figure 4 shows a recreation of two users, both with masks and with electronic anti-aerosol devices in place. The user with device 1b, wears the device turned off, and it is observed that in an environment with viruses suspended by aerosols, these viruses, represented in the drawing, by dots of different sizes, come into contact with the face, eyes and with the mask of the user, therefore everything would be contaminated, being possible that the user could spread, through the gaps or wrinkles in the mask or by contact with the eyes.
    [0066] However, in the recreation of the user's operation with device 1a, it is observed that none of the viruses can come into contact with the user's face, likewise they cannot impact against the eyes or against the mask since they cannot cross the barrier of air current, avoiding contamination of the surfaces. It is observed illustrated in the drawing by means of lines with arrows, that the direction of the filtered air is upwards, and that it forms a surrounding and front shield, protective against particles and viruses, which due to their microscopic size are pushed upwards, with the powerful air current, protecting the user of the device on 1a and not protecting the user of the device off 1b.
    [0068] Figure 5 shows another incarnation of the anti-aerosol device, in which the casing 1 has several external fans 8b, positioned in the upper area of the casing, these fans when in operation cause the air to enter through the holes of the casing 4, where the air filters 10 are positioned, generating strong upward currents and surrounding the face of the user wearing the device, protecting him from the contagion of viruses in aerosols or by means of drops, as well as other elements or particles harmful that are in the air and can be expelled by the continuous ventilation generated.
