DEVICE FOR PRESERVATION AGAINST CONTAGES OF PATHOGENS A

THROUGH THE FACE

OBJECT OF THE INVENTION

The present invention relates to a device for preservation against contagion of pathogens through the face, especially coronavirus.

BACKGROUND OF THE INVENTION

The world is currently threatened by the spread of the coronavirus pathogen, the effects of which are well known, with a death rate not seen in recent decades, which has forced governments to restrict the movement of people and stop activity. economic record unprecedented in recent times.

It is known that the pathogen is spread mainly through the face, either by inhaling droplets generated by coughs or sneezes of previously infected people, even asymptomatic, which makes it even more difficult to stop the spread of the disease, or by touching the face after having touched surfaces previously contaminated with ease by said droplets when falling, or when being touched by other infected persons. When touching the face, the virus penetrates through the openings of the same (eyes, nose, mouth ...) and comes into contact with the body fluids of the same, starting colonization.

Obviously, the inventor does not know of any measure similar to that proposed in the present invention, since it is a new-onset disease and the entire world community is in check, that if similar solutions were available, they would have already been disclosed in the media. communication. Yes, mouth and nose protection masks are known, but on the one hand they make breathing difficult and on the other hand they do not protect the eyes, and it cannot be verified that they are very useful against infections, since at the moment they are only Recommended for carriers of the virus, to avoid the spread of its droplets, unlike the invention, which is designed to avoid getting infected, not infecting third parties.

DESCRIPTION OF THE INVENTION

The device for preservation against contagion of pathogens through the face of the invention comprises, in its most elementary version, a formally and dimensionally suitable support to be fixed on the head, in which there are arranged first nozzles directed towards the proximal zone front of the user's face to generate a protective curtain of purified air; further comprising:

-some first elements that generate an air flow (fans, turbines, etc. of adequate size) to generate the protective air curtain,

-a filter that is interposed in the air flow,

-a windows for the admission of outside air to generate the air flow,

-a filter disinfection element, and

-a power supply (in addition to the necessary elements for regulating the first elements that generate an air flow and the disinfection element).

In this way, a clean and disinfected air flow is achieved in the proximal anterior area of the user's face (the one immediately in contact with the eyes, nose and mouth), so that only this air will be inhaled with the additional advantage that this flow or curtain, in addition, expels or disperses possible residual droplets present in the air and prevents them from being inhaled. That is, it achieves a double effect: on the one hand, it provides a flow of disinfected breathable air in the nose and mouth area, and on the other hand, it prevents residual air droplets from approaching the openings of the face, including the eyes. environment, by moving the air curtain generated to them. Thus, contagion of the wearer of the device is avoided.

In addition, it has the following additional benefits:

-by having a filter disinfection element, its useful life is very long, unlike disposable masks, which also pose a health (due to the subsequent management of this waste) and environmental risk.

-the user will breathe deodorized air, free of environmental pollution.

-It is also useful for allergy prevention, although it is not recommended for people with dry eye syndrome.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The device (1) for preservation against contagion of pathogens through the face of the invention comprises a support (2) formally and dimensionally suitable to be fixed on the head (3) of the user, in which are arranged first nozzles ( 4) directed towards the anterior proximal zone (100) of the user's face (see figs 2 and 4) to generate a protective curtain of purified air (5); further comprising:

-some first generating elements (6) of an air flow (7) (turbine fans of adequate size) to generate the protective air curtain (5),

-a filter (8) that is interposed in the air flow (7),

-some windows (9) for admission of outside air to generate the air flow (7),

-a filter disinfection element (8), and

-a power source (10), in addition to the necessary elements for regulating the first elements that generate an air flow and the disinfection element.

Most preferably, the filter disinfection element (8) comprises a first UVC luminaire (11), the filter (8) being made of translucent materials, ideally having a printed mirror (80) in said filter, since it has been Experimentally proven that it increases the exposure of the filter (8) to disinfectant light by much more than double. This is how it is achieved that UVC light, whose wavelength is biocidal, reaches to the entire body of the filter (8) and produce effects. Ideally, this first UVC luminaire (11) has means of generating UVC light with a wavelength between 222 and 265 nm and, at least 10 mW of power, being preferred that it has a wavelength of 222 nm and 2.4 W power.

For its part, the filter (8) comprises a filter of category HEPA E11, at least, it already has sufficient effectiveness for the size of the droplets carrying significant viral load. Furthermore, it is preferred that the filter (8) and the first air flow generating elements (6) are dimensioned so that the air takes at least 30 seconds to pass through the filter (8), since according to various tests consulted by the inventor, for a power of 10 mW of UVC light, in 30 seconds 99% of the pathogens are eliminated, so for the proposed powers (2.4 W, 240 times higher) the effectiveness should be close to 100%. It is also preferred that the filter (8) has an operating flow rate of at least 10 CFM (cubic feet per minute), that is, about 45 times higher than the respiratory flow rate of an adult, more than enough to guarantee effectiveness.

According to the invention, the possible arrangement of an ozone generator (12) (see figs 1 and 3) and of second generating elements (13) of a mixing flow (14) (see also fig 4) of ozone with air; the support (2) comprising second nozzles (15) for expulsion of the flow of mixture (14) directed towards the anterior distal area (101) of the user's face (that is, the one that is beyond the proximal area of the face (100) already defined), and comprising elements for triggering the mixture flow (14) and a connection to the power supply (10). In this way, in addition to repelling possible detected droplets, it is possible to exert a biocidal function on them, and deactivate them, even benefiting third parties. The air of this flow of mixture (14) can be derived from the filter (8), or have a specific filter (80) and additional disinfection elements (110) (see fig 3). As for the mixing flow trigger elements (14), they preferably comprise PIR proximity sensors (16), which will trigger the trigger upon detecting proximity of objects to the face, sized according to the sensitivity that is set.

This ozone generator (12), as well as the second generating elements (13) of the mixing flow (14) are preferably dimensioned so that the mixing flow (14) has an ozone proportion of at least 15 mg / h, a flow rate of at least 10 CFM and a speed similar to that of a human sneeze (100-160kmh). In this way it achieves a biocidal function of the possible pathogens in suspended droplets, and also a mechanical repulsion of them.

Additionally, the possibility of having a vibrator or buzzer (16a) on the support (2), and proximity sensors (16) (PIR for example) to the face (they can be the same ones that trigger the mixture flow (14 ), thus also firing the ozone mixture and further reducing the risk) associated with the vibrator or buzzer (16a) to start it up when bringing the hands to the face, as a warning to the user, in case it is involuntary movement and can avoid it.

To complement the functionality of the device against contagions, it has been envisaged that it can also comprise forensic light lamps (LED) (18), ideally also arranged on the support (2), and directed forward, operable by the user using push buttons for example, not represented. As the forensic light is capable of detecting, on any surface, traces of organic fluids with risk of viral load, activating it for example when sitting in front of a table or keyboard (for example doctors working in ICU), they can detect these remains. To do this, ideally forensic light lamps (18) comprise at least 2 different wavelengths (390/395 nm -ultraviolet-, 450 nm -blue light-, which detect, among others, traces of blood, saliva, sweat , hair and fingerprints) with vision through colored filters, for example glasses. If these traces are detected, it is possible to act to deactivate them.To do this, or even independently of the availability of forensic light, the invention has provided that the device (1) can comprise a second UVC light (19), ideally also arranged on the support (2), and directed forward, to irradiate with this light these possible remains detected by the forensic light sources (18), or others. This second UVC luminaire (19) can, for example, be made up of six lamps with a wavelength of 390 nm and a power of 10 mW each, therefore not harmful to humans. This characteristic also has synergy with the ozone mixing stream, if implemented jointly, when deactivating the virus.

Regarding the support (2), it is preferred that it be in the shape of a crown, with adjusters (25), to fit the user's temples and not move from position, and it is ideally provided with a front visor (20) where they are arranged Suitable functional elements, such as the nozzles (4, 15), the forensic light lamps (18), and the second UVC light (19), since from this position better angles are obtained for their functions. At In a preferred example of the invention, in the support (2) there are also arranged the first generating elements (6) of the air flow (7), the second generating elements (13) of the mixing flow (14) of ozone with air, the filter (8), the filter disinfection element (8) and the outside air intake windows (9), the necessary regulation elements (23) and the control unit (24) being preferably also arranged therein.

In addition, the support (2) can comprise (see fig 2) a removable transparent screen (21) (made of acetate for example), usable for example in environments with high viral load (hospitals), which can be fixed, for example, embedded in a slot , not represented. On said screen (21) the colored filters (21a) necessary to appreciate the traces of biological remains can be placed with the forensic light, preferably arranging said filters in stripes, for example lower ones as seen in fig 2, so that accommodating the angle of view, similar to the use of progressive glasses, will be displayed through one filter or another.

The provision of a support module (22) (backpack or similar) where the power supply (10) -type power bank for example easily interchangeable and rechargeable- can be arranged, which can have a connection to a mobile charger. to work with the same plugged in. In addition, the device can be complemented with a transport case, not shown, where to have the support (2) with everything that goes inside, as well as the support module (22), the screen (21) when disassembled , etc, everything in general that needs to be sterilized, in addition to being able to serve to transport gloves, glasses, beads, etc. In this way, even with the support with the rest of these elements stored in the closed case, activating the disinfectant elements of the device (mixing flow (14) with the ozone generator (12) in operation, and second UVC luminaire ( 19)) can be disinfected). Even the suitcase can have openings with a lid, so that by leaving the suitcase generating a flow of mixture, which would come out through the openings of the suitcase, small rooms can be disinfected, such as the interior of a car, provided they are not occupied by people at that time, due to ozone toxicity.

In this way, there is a device that is capable of combating contagion from all fronts contrasted in the various information that has been provided to the public.

Having sufficiently described the nature of the invention, as well as the way it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications in detail as long as they do not alter the fundamental principle.
