PERSONAL PROTECTION DEVICE AGAINST VIRUSES AND PARTICLES IN AEROSOLS AND FOR THE VENTILATION OF SPACES

TECHNIQUE SECTOR

The present invention is included within personal protection devices.

BACKGROUND OF THE INVENTION

Health authorities recommend protecting the respiratory tract and eyes when there is a risk of infection by aerosols. It is also recommended to protect the eyes and respiratory tract against harmful elements or pollutants that are toxic or harmful to health, and in some cases it is even recommended the protection of the skin and hair, through the use of domes, facial screens and protective caps. Air pollution is the introduction of viruses, particles, biological molecules and other harmful substances into the atmosphere, causing diseases and infections, as well as this pollution causing death to humans. The quality of the air in indoor places such as hospitals, or crowded places can be bad and the atmosphere can be loaded with viruses in the form of aerosols, likewise the pollution and quality of urban air in most cases is usually bad for people's health.

These harmful elements penetrate the human body through the respiratory system, the eye organs and even through the surface of the skin or hair, developing or infecting a multitude of diseases or health problems, such as respiratory disease of the Covid19, which has become a serious global pandemic due to the transmission of the SarsCov2 virus, a virus that can be spread through aerosols.

Following safety recommendations, protective elements are usually used such as masks, face shields, airtight glasses and hats, among other types of facial protection that are most used in laboratories and by professional personnel, such as domes, helmets and diving suits. . All of these protections aim to prevent elements or particles that are harmful to health from coming into contact with the user's eyes, respiratory tract, skin and hair.

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, likewise health professionals in addition to using masks , they must use airtight protective glasses or face shields to protect the eye area since it is an important route of contagion, they must also cover their hair and wear a non-permeable protective suit, having to be covered as much as possible against contact with virus.

An individual infected by a virus can infect other people through the expulsion of nasal or oral secretions, either in the form of fluid droplets of different sizes, or in the form of aerosols, these secretions can be produced in various ways, when the infected person sneezes, coughs, or simply through the action of speaking or breathing, among others.

This is why health authorities, among the most important recommendations to avoid infections 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 with their secretions directly to a healthy person and thus avoid the spread and viral infection between people.

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, transportation, schools, universities, hotels, restaurants, bars, clubs, theaters, gyms, shops, supermarkets and practically anywhere indoors. At the same time, the safety distance between individuals is also difficult to maintain in open places that are crowded by many people, and likewise the social customs established in most cultures and countries mean that the safety distance is not maintained. at social gatherings or family gatherings. This lack of rigor in maintaining distance between people or the difficulty of being able to do so is a high risk factor that ultimately usually ends with a notable increase in the spread of a virus. 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 infected patient, therefore than the use of masks and airtight glasses, the only thing that protects them against possible contagion or contact with viruses. Protective masks must be as effective as possible and must be self-filtering and as watertight or airtight as possible, but in most cases, both among professionals and among the general population, so-called “Surgical” masks are usually used. ” or “FPP”, none of these masks are completely tight around their contour, so if a patient, for example, sneezed or coughed directly on the healthcare professional, the mask could not avoid stopping the entire viral load, and could not prevent viruses from entering through the gaps in the contour of the mask or glasses and thus reaching the respiratory or ocular tracts, causing contagion. Therefore, the typical masks mostly used by the population serve to reduce or reduce the expulsion of oral or nasal secretions from infected individuals, but they cannot stop the entire secretion, nor do they manage to prevent the approach or physical impact of the virus against a third person, against the surface of the skin, hair or even against the physical surface of masks, glasses or facial screens, leaving these elements or surfaces contaminated after contact with the viruses, therefore not being able to completely protect a person. healthy user from possible infections, therefore, health authorities place special emphasis on the population maintaining a safety distance of several meters between people, thus trying to prevent viruses from reaching and impacting healthy people.

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 through the air, in fact as indicated in different studies, this may be the main means of contagion, aerosol transmission.

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 smaller size that an infected person can release or launch through oral or nasal secretions, but It is more than likely that most people become infected by inhaling the virus that circulates in tiny particles that remain suspended in the air in the form of aerosols.

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 air for hours. environment and travel distances beyond the two meters established as a safety distance between people. Above all, and especially in indoor places that do not have good ventilation, the risk of suspended viruses floating in the air in the form of aerosols increases the risk of contagion.

The World Health Organization (WHO) has recognized the existence of this airborne route of contagion through 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 suspended for hours in the environment. As occurs with environmental pollution in the atmosphere, due to the chemical substances emitted, dust, harmful gases, smoke, as well as other health problems, generated by mites, bacteria, pollen, etc.

Inhalation by a healthy individual of contagious microscopic particles in the form of aerosols, which remain suspended in the air for hours, may be the main route of infection. Likewise, the time that these contagious microscopic particles remain suspended floating in the air, with the risk of accumulating and infecting someone, depends above all on the ventilation factor. In this sense, specialists recommend avoiding activities in closed places, and the need to direct all possible activities outside, since it has been observed that contagion is less likely in adequately ventilated places without allowing viruses to accumulate. in the environments. In fact, there are electronic devices that measure air quality, warning when a specific space or place has air that is too dirty or stale. These measurement systems are useful to know the danger of a specific space or place.

In the case of virus transmission by aerosols, the protections normally used by the population, such as surgical masks and other models of masks and maintaining a safety distance of two meters, are not sufficient to protect against airborne viruses. or that are suspended, in fact, given the increase in cases of contagion, the authorities carry out population confinements, to prevent the spread of viruses between people or even between animals and people and vice versa.

Likewise in another sense of protection as we have explained, in the air Allergic elements such as pollen particles or mites can be found, different types of microorganisms, germs or bacteria can also be found in the air, especially in hospitals or closed places, and likewise, the air can contain polluting elements such as smoke, liquids or gases, which can penetrate the majority of the most commonly used masks or glasses through gaps, wrinkles, lack of fit or through the transfer of the fabric or material with which they are made.

In the event that the protective elements come into contact with viruses either by direct contact through sneezing or coughing from an infected person, or through 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 masks, to replace them with a new one, since through contact with a virus, said protective pieces become contaminated, because viruses can Stay active for hours on most surfaces. These protective elements act as physical barriers to stop viruses when there is contact, but they remain dirty or contaminated when physical contact with the viruses themselves has occurred. Another problem that society faces regarding the spread of diseases transmitted by air or aerosols is the discomfort suffered by mask users. People who are forced to wear masks for long periods of time tend to suffer from discomfort when breathing, since many times an extra effort must be made when inhaling, which causes many users to remove or lower the mask for a moment to be able to inhale more easily, this means 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 feeling overwhelmed. This feeling of overwhelm is especially produced by the user's own exhalation. The air that is exhaled carries with it carbon dioxide, in addition to generating steam and heat, which causes a higher temperature to be maintained inside the mask and the feeling of lack of air is greater.

This vapor generated by the use of the mask that condenses inside, causes a user's glasses to fog up with the vapor of the exhaled air. This condensed air escapes through the fabric, or through the top of the mask. the mask and rises to the glasses producing fogging, having the The user must manipulate the glasses to clean them or lower the mask to allow air to enter.

These problems of feeling overwhelmed, lack of air, heat and fogging of eye protection are undoubtedly problems for the general population, but they are even more so for health professionals who must remain with the elements of protection throughout the work day. protection placed in closed places such as hospitals, precisely health professionals use airtight protective glasses, in this way they ensure that the glasses do not fog up and that viruses cannot enter or contact the eyes through the gaps or sides of the glasses. glasses, but they cannot prevent the surface of the glasses from being contaminated by contact with viruses.

As explained, respiratory protection masks can cause difficulty breathing in people with respiratory problems, such as people with asthma or other respiratory problems. In serious cases of this type of illness, medical professionals can reach to advise against the use of masks for these people, leaving these people unprotected against airborne infections or being able to easily infect others if they are infected.

Another problem of fundamental importance when it comes to controlling the spread of viruses is what occurs when drinking or eating. As is known, health authorities have substantially reduced capacity or even closed 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 being infected on their part, in the event that it is positive. to a contagious airborne disease such as Covid19. There is an even greater risk in the case of eating in the interior area of bars or restaurants, since this risk is increased by the lack of ventilation or air currents, which can lead to viruses remaining suspended in the air for hours and since the diners are not protected in any way since they cannot wear the mask while carrying out the act of eating or drinking, this situation is dangerous due to the transmission of viruses in the form of aerosols.

For all these reasons, it is necessary to develop a device that increases safety against the spread of airborne diseases, such as virus transmission in the form of aerosols, a device that is portable and easy to use, that purifies the air near the user. A device with batteries rechargeable by conventional charging on the electrical grid, or by means of photovoltaic or solar energy, which can be operated directly by photovoltaic or solar energy. A device that prevents direct contact of viruses against the facial area and even against the side and back area of the user's head and that can prevent direct contact of viruses with the surfaces of protection, such as masks. or glasses, which acts in this sense as a protective barrier, which prevents surfaces from being contaminated by contact and which prevents infections from occurring by avoiding contact of viruses and other toxic or harmful elements with the eyes, nose, mouth, the user's skin and hair.

That can protect people even when they are not wearing protective masks, as in the case of when these people are eating, drinking or doing a sporting activity.

An advanced device that protects people even if a safe distance cannot be maintained, for example, in doctor's offices and hospitals, on public transport, on flights or trains, in work activities such as meetings or family gatherings, in schools and universities, at sporting events, among many other activities.

A device that increases ventilation and protection both outdoors and indoors, that protects the facial area, eyes and the area around the user's head and that protects the upper area of the body, shoulders, chest, back and clothing. clothing from the approach of viruses, through the continuous generation of treated and/or filtered air currents, which form an invisible physical barrier, which prevents the approach of harmful external elements to the user, even when the respiratory protection mask cannot be used.

A device that eliminates the feeling of lack of air, that helps eliminate the heat and steam produced by the. And in the same way that the device can protect users from other elements that are in the air that are harmful to health, such as pollen, dust, mites, bacteria, germs, smoke, gases and other elements that are transported. by air or by aerosols.

Likewise, the device itself that generates filtered air currents performs self-cleaning of the air and/or disinfects the air filters, through portable generators of germicidal ultraviolet light.

A device that is intelligent, that can transmit and receive information and wireless orders through other electronic devices, which can analyze the air quality and communicate it to the user, which warns about the battery life and the replacement of air filters among other notices, such as recommending the use of light ultraviolet germicide in hazardous environments.

In short, it is necessary to create a device to protect the upper area of the body, the eye area, the face and surrounding the user's head, which, in a portable way, can exponentially increase safety against infections by aerosols among other harmful elements transported. through the air. That complements safety elements such as respiratory protection masks and that can protect people from close proximity and contact with viruses even when they are wearing protective masks or not, even when the safety distance against infections cannot be maintained. .

A device that itself generates aeration, ventilation, purification and air currents in the form of personal protection. A device that can protect users even during a meal or dinner, where the mask cannot be worn and where it is difficult to maintain a safe distance from other diners, especially one that is effective in indoor places where there is a greater risk of infections. Likewise, it allows health professionals to increase protection against the approach of harmful particles and/or viruses, prevents viruses from coming into contact with PPE protection elements such as masks, hats or the upper part of the suit, and even prevents the approach of viruses to the skin and hair, a device that relieves the feeling of lack of air and reduces the temperature generated by the use of masks and PPE equipment, in long periods of the work day, as for example in the case of health professionals.

Likewise, it should be a device that protects athletes, for whom it is not possible to use a mask during physical activity, due to the lack of oxygen or the respiratory overexertion they have to make, which leads to lower physical performance. , which may be of special relevance among elite or professional athletes.

A device that increases ventilation in closed places and prevents the stagnation of viruses suspended in the air.

EXPLANATION OF THE INVENTION

The main advantages provided by the present invention make it a portable device for protection against the contagion and contact of viruses by aerosols, against contaminating elements and also against other harmful elements or allergens found or moving in the air, which offers greater security to the user in addition to the basic elements of protection such as respiratory protection masks and even that this device has the ability to protect even without the use of masks.

The invention is about an advanced device that is easy to use and portable on the user's head or forehead, a device that protects against aerosols and purifies the air in the atmosphere close to the user, which has one or more electronic generating devices. ventilation and blowing, achieving eye, facial and even protection that protects around the user's entire head and in all directions of the upper part of the body. The device of the present invention can integrate one or more air filters, such as active carbon filters or other filtering materials, although preferably and not limited to, the anti-aerosol protection device of the present invention has filters called HEPA. (from English "High Efficiency Particle Arresting", or "high efficiency particle collector"), or filters called ULPA (from English "Ultra Low Penetration Air"), both filters base their effectiveness on the use of braided fibers responsible for screening particles and letting only air pass through, focus on the ability to filter particles of one size or another by each of the filters.

99 percent of the particles we breathe during an exhalation measure 10 μm or less, and they can be retained in the lungs and cause negative effects for the body, as we have explained. Each of the two filters has the following minimum designation and, therefore, the key to their differences: HEPA (H13): 99.99% efficiency for the filtration of particles 0.3 microns in diameter or larger. ULPA (U15): 99.9995% efficiency for filtration of MMPS particles (0.1 - 0.25 microns). Both filters have the capacity to stop most harmful particles, including viruses such as SARS Cov2 among others, as well as other irritating allergens or harmful harmful elements found in the air, the device generating currents of filtered air and /or treated, cleansed and purified, creating a protective barrier surrounding the user's head and face and the upper area of the body, back, shoulders and chest, preventing the approach and contact of particles, harmful elements or virus to the wearer of the device, thus protecting both the area eye and respiratory tract and in turn preventing, for example, viruses from coming into contact with the surface of the skin, with the user's hair and even with the surfaces of the mask, the protective cap and the upper area of the suit. An advanced and portable device, which may have the ability to self-clean and disinfect the air that is introduced into the device and disinfect the air filters, which may have one or more electronic systems of portable ultraviolet light generators. disinfection with a germicidal, bactericidal and virucidal effect, which would exponentially lengthen the useful life of the air filters and increase safety with the purification of the air that is introduced into the device and expelling it once clean into the nearby atmosphere and surrounding the user.

The device of the invention is characterized by integrating one or more internal blower fans in the device itself or in the external area, which generate a continuous stream of clean and disinfected air, using the outside air, treating it with ultraviolet light and/or filtering it. this, and subsequently throwing or blowing it, not allowing the approach and impact of viruses and any other particles found in the air against the user. This device generates continuous air currents in an upward and downward direction with an approximately truncated conical profile.

These continuous currents of clean, purified and treated ascending and descending air act as an invisible barrier to prevent the approach of microorganisms, viruses or harmful elements and particles to the user, producing the push of these out of the reach of all the eye area, facial area, outside the respiratory tract, outside the skin of the face, neck, glasses and mask. The device of the invention prevents the user's glasses from fogging up when masks are used together; this is a generalized problem that is solved with the use of the device of the invention. Taking advantage of the microscopic size of microorganisms, harmful elements

in the air or, as in the case of viruses, any particle exhaled by an infected person or any microorganism or virus that is floating in the form of an aerosol, will be expelled by the air current generated by it or the fans of the device. , an effective way to maintain a clean, ventilated atmosphere free of particles and viruses, surrounding the user, thanks to the continuous generation of air currents in all directions, these air currents not only They act as a physical barrier stopping and expelling viruses through contact with the air current generated, but also the current of filtered air continuously generated by fans or blowers, prevent contact of viruses from occurring, eliminating risks of contact, infections and preventing surfaces from being contaminated, since the air current generated expels the viruses before contact occurs, preventing viruses or particles from passing through the air current generated.

The purified air generating electronic protection device of the invention can be easily and comfortably worn by the user, preferably and not limited to in the form of a helmet, cap or headband, so that it is preferably positioned on the head, and of This mode directs the air upwards and downwards, protecting the entire facial, eye and head area, including the skin and hair and the entire upper part of the device wearer's body. Likewise the casing of the device

It contains fixing parts, which prevent slipping or unwanted movement once placed, said fixing parts can be the device casing itself, they can be straps, tubes, tapes or adjustment rubber bands, with or without measurement regulation. , elastic or fixed. Air-generating protection device, which may or may not have a facial protection screen, glass or transparent materials such as plastics, among others, which may be sun protection, graduated or both. Portable device characterized by integrating at least one electronic ventilation or blowing system, which introduces or sucks air from the outside and once this air has passed through the ultraviolet disinfection system and/or through the air filters, it subsequently directs that clean and purified air either by blowing directly through it or the mobile external fans, or through it or the internal fans, which subsequently send it to the different mobile air outlet nozzles that it can have, generating several streams of clean air and directed, creating a continuous barrier of safety.

The air barrier generating protection device has at least one fan or blower to introduce air from the outside into the housing of the device and expel it to the outside by directing the clean blown air to the desired area or areas. The device that acts as a blower generates a continuous intake of air that is filtered and/or treated with germicidal light, and also a continuous output of purified air to the desired area. These ventilation and blowing systems are preferably small in size, they are silent devices for Avoid noise in operating mode.

The invention is characterized by being able to integrate portable electronic systems that generate ultraviolet light, through, for example, the use of UVA light lamps or, preferably due to their tiny size, diodes with technology called ultraviolet (LED) and/or with laser diode (DL) technology. ) which is a semiconductor device similar to an LED but that under the appropriate conditions emits laser light, germicidal ultraviolet light, LED or laser, based on low-frequency ultraviolet technology, emitted and directed, which allows the destruction of viruses among other pathogens, by means of I use generators with the required nanometers for germicidal action and minimal energy consumption. They are preferably positioned inside the body of the device, once placed or placed in place, by pressure, thread, or by any type of fixation, these ultraviolet light generators are preferably integrated inside the device and not limited in the same place where the air inlet area is located and/or where the filters are integrated, in a sealed area that does not allow the UVC light to escape towards the user, in this way they overlap, remaining one on top of the other, being able to perform self-disinfection of the physical surface of the air filters, increasing and lengthening their useful life.

These ultraviolet lights, called germicidal, are effective in the rapid disinfection and elimination of microorganisms such as viruses, germs and bacteria, among others, by exposing ultraviolet light to surfaces, liquids and air. The ultraviolet light generators can also be integrated into the device in the area intended for disinfection of the air that is introduced inside, although the disinfection carried out by this germicidal light is considered rapid when it comes to ending the activity of the viruses, germs and bacteria in the air, it is possible that the device of the invention needs to retain or force the air that enters through a guide path to have one or more guide tubes, which can have any structure or shape as long as a air passage, for example with a linear shape or spiral or labyrinthine channel, which acts as a circulatory channel for the air that enters and forces this air to circulate inside this area and thus increases the time at which the air It is subjected to germicidal light radiation, making the ultraviolet light treatment in the air greater and therefore more effective in disinfecting and deactivating viruses and microorganisms.

Far UVC light is safer for humans than UVA light, since UVC light has a very limited range of nanometers and according to the latest studies, this UVC light cannot penetrate through the outer layer of dead cells. of human skin or the tear layer in the eye area, so it is not a danger to human health. However, viruses, being much smaller than human cells themselves, far UVC light can inactivate them by reaching their genetic material, attacking the molecular bonds that hold the DNA together.

Said ultraviolet light generating 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 exposure to the user of the light, through an opaque protective piece around its contour, casing or sealed chamber, which only allows the emission of light to the internal part of the system, such as the linear, spiral or labyrinth-shaped channel, through which the air enters and the entire path it travels through the interior of the casing and/or or directly directed the germicidal light to the air filters, having a reduced light beam power limited to the necessary distance where it must act, eliminating the risk of contact with the user's skin or eyes.

The electronic devices that make up the device are small in size for integration and weight reduction, all of them have on and off buttons and/or different power selections, so that the user can activate or deactivate them when necessary or when you want, all of them powered with built-in rechargeable batteries, which allow their use without the need to be connected to any electrical network during use and you can use, for example and not limited to, a rechargeable mini USB line to recharge through the electrical network or by exchanging energy. with another electronic device and/or through magnetic electric charging, as well as another possibility of energy source, the device can have photovoltaic solar panels, and therefore is autonomous and does not need electric light for its operation or for charging the batteries. , this technology offers access to energy independently of existing electrical networks. The device of the invention works where necessary, both in urban environments and in rural areas where it is difficult to have access to electrical energy as well as in catastrophic areas where there is no electrical network available, an immediate and efficient solution that allows the user to be protected against to viruses and harmful particles in aerosols, anywhere. The device of the invention can serve as an auxiliary charger to charge other electronic devices, for example a mobile phone without a battery in a place. remote without electricity, by exchanging solar energy through the USB or mini USB port of the device of the invention, therefore having access to energy where necessary and independently of electrical networks and using the sun and/or light as a source of energy. clean and renewable energy. In the case of the use of photovoltaic or solar panels that the device may have, regardless of whether they include conventional recharge batteries in the electrical network, it would allow the device to operate and/or the batteries to be recharged autonomously by means of the action of radiation with solar energy outdoors and with artificial light radiation indoors, increasing the capacity of use and for example leaving the conventional battery as a reserve, or allowing use in places that do not have electrical energy, such as remote places or places that have suffered catastrophes and have lost the electricity grid, as well as in remote places such as beaches, mountains, field work or farms with animals that can also be carriers of viruses and diseases, mites and hair, therefore harmful and/or contagious to human beings.

The incorporation of photovoltaic or solar panels makes the device more ecological. Likewise, by being able to incorporate electronic ultraviolet disinfection systems to disinfect the air filters, the life of the filters is considerably increased, reducing the generation of filter waste into the environment. and preferably using recyclable and recycled materials for the manufacture of the casing, being an environmentally friendly device.

The technical characteristics of this advanced anti-aerosol device form a technical effect that interacts, generating a filtered ventilation current for hours, against particles that approach the user. Making this intelligent protection device that generates air currents, a device eye protection and respiratory tract protection, through the continuous generation of a stream of filtered air and/or treated with germicidal light, to avoid contagion by aerosols and the approach of particles or harmful elements to the user.

The World Health Organization has established a minimum safety distance between people of two meters to prevent viruses from coming into contact between individuals. This anti-aerosol device prevents viruses from coming into contact with the respiratory tract. facial area, eye area, against the surface of the skin and hair of the user of the device even if it is not possible to maintain a safety distance.

Likewise, the health authorities have advised that closed places should be as ventilated as possible with air currents, so that viruses do not remain in suspension, which is why this device also ventilates closed spaces individually and on its own. and prevents the formation of stagnant air where viruses can remain in suspension, being highly recommended in closed spaces or with poor ventilation. As an example, if inside a hospital, the workers were wearing and activating the anti-aerosol devices of the present invention, the ventilation generated by each of them, multiplied by the number of users, would be sufficient to ventilate a room and avoid the stagnation of viruses in the environment during work activity. Users would be properly 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 approach of viruses to the eye, facial, or head area. of the user, especially in crowded public spaces, or such as airplanes, trains, subways or public transportation in general and as well as in many other places, in which the safety distance is difficult to maintain, minimizing the risk of exposure, increasing and generating air currents and ventilation, preventing the approach of viruses to the front and side areas of the body and surrounding the face, in addition to cooling and relieving the sensation of heat. Likewise, the device of the invention, for example in the form of a protective cap that generates an anti-aerosol air current, could protect athletes who, due to their physical activity and need for respiratory overexertion, cannot carry out the activity with masks. protection, which would generate a lack of oxygen, a feeling of fatigue and require excessive respiratory effort on the part of the athlete, which could affect their physical performance and even your health. The cap device that generates anti-aerosol currents would allow the athlete to be protected comfortably, without the need to wear a mask and avoiding the approach of viruses to the frontal area and surrounding the face, in addition to cooling and relieving the sensation of heat. In the same way, the anti-aerosol device would allow you to protect and avoid infections even when, for example, you are in an indoor restaurant, eating without a mask, preventing viruses from reaching diners in an effective and comfortable way. Likewise, the present invention does not only serve to protect against infections and contamination, as explained above, the device can also be very useful to increase safety in jobs in which people are affected by smoke or dust. , such as, for example, it would be a device that would greatly help firefighters who lose vision due to smoke, the device of the invention being compatible with approved helmets or the device being integrated into them, these devices of the invention generating Currents of treated and purified air would ventilate the ocular area, allowing better vision, keeping smoke away. Likewise, in jobs that generate a lot of dust such as mining, the logging industry, earthworks, masonry, among many other activities, the dust generated can affect the worker's breathing and also the vision of the worker. device of the invention, would protect both breathing and vision, continually keeping the dust generated out of the worker's breathing zone and field of vision.

BRIEF DESCRIPTION OF THE DRAWINGS

Below we briefly describe 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 it:

Figure 1 shows an example of the device of the invention, placed and worn by the user and seen in profile, casing or main body of the device 1 in the form of a headband and forehead, attached to the sides by pressure. It is noted the positioning or coupler element 2 of the device housing, which houses the different protection and air purification elements and/or the electronic systems, for example ventilation 5. Element 4 is shown, a button for controlling the functions of the component ventilation, suction and blowing of the device. In the upper and lower area of the device and in its contour, there are multiple air outlets, mobile nozzles 3a and 3b, which allow directing, controlling, fixing and pointing the air in any direction, each of them independently, creating a mesh. or barrier of purified and disinfected air currents.

Figure 2 shows a front view in which the user is using the device, the device 1 is in operation with the light indicator buttons 4 on and activated, therefore the suction fan 5 integrated into the positioner or coupler 2 , is continuously introducing air from the outside into the interior of the device casing, the air is pushed out in the form of a flow injected by the mobile nozzles 3A and 3b, which can each move independently, to direct, control and aim the air correctly in any direction, in this representation with descending and ascending air flow direction. in which the user only has the air vents of the device activated. In a representation using lines with arrows, it can be seen that the directions of the air flows form a network crossing each other surrounding the facial, ocular and lateral areas of the user's head, completely protecting the user from contact with viruses in aerosols. , clean air currents that push, block and prevent microscopic viruses from passing through said air barrier.

Figure 3 shows an example of the device of the invention in which the casing or main body of the device 1 can be integrated into a cap, the generic cap being able to integrate the aerosol protection components, all forming a synergy and a protection set. Front, side, rear and perspective views of a generic cap with integrated protection elements are shown, with only the positioner or coupler 2 facing outward, where the filtering elements and electronic elements are integrated, that is, the filter elements. of high-efficiency air particles or HEPA filters 9, a filter that is positioned directly next to the UVC laser LED ultraviolet light generator component 8 that disinfects the surface of the filters, the electronic ventilation and air suction component 5, components that all are finally overlapping by component 7, a protective filtering grid as a mesh or net for larger particles found in the air. In the front view of the cap, the operation control button 4 is shown for controlling the functions of the element 5, and in the rear view of the cap, the operation control button 24 is shown for the control of the functions of the UVC LED disinfection element 8. Finally, in the center of the image it is shown how the protection elements 7 and 9, the electronic systems 5 and 8, the battery 13 and the charging port 12 are integrated into a generic cap. , , remaining in the visor of the cap and around it, the multiple mobile air outlet nozzles 3a in the lower area and 3b for the upper area, through which the clean air subsequently emerges as an injection flow.

Figure 4 shows a front view and a profile view, in which users are using the device of the invention integrated into a cap, transforming it from a simple sun protection cap into an aerosol protection device. It is observed both laterally and frontally that the multiple air flows generated protect the facial, lateral and surrounding area of the head, creating a mesh or interwoven network of air flows, protecting the respiratory tract, eyes and facial skin. , the user's hair from contact with viruses in aerosols and ventilating the upper area of the spaces where the user is located.

Figure 5 shows a representation of a meeting of three people in which security measures are not maintained, nor the separation distance between people. On the left, user U1 can be seen, with the device of the invention placed and in operation, who is completely protected by the multiple air currents around his head, a current that the viruses, represented in the figure by small points in the environment, they cannot cross and when they approach the air flows, they are blocked, pushed and expelled, avoiding contact and contagion, on the skin, hair, in the eyes, in the respiratory tract and throughout the entire body. upper body area, head, neck, shoulders and chest of user U1.

To the right of the drawing, there is U2, an infected person, who is not wearing any type of protection and who is expelling viruses in the form of droplets and/or aerosols that are represented by small dots suspended or transported in the air.

In the center of the drawing, you can see U3, a person who uses a mask. respiratory protection, but he does not use protective glasses, so the viruses can contact the eyes and cause contagion. It is also observed how the viruses reach the skin, hair and the entire upper area of U3's body, causing contamination of The surfaces.

The user of the U1 device being the only fully protected individual, even though he is not wearing a respiratory protection mask, nor maintaining a safe distance between people, even so the viruses cannot produce contact with any area or surface of the upper area of U1's body. and therefore cannot cause contagion.
