DESCRIPTION

Dispensing and aspiration device for a filtered air flow

TECHNICAL SECTOR

The present invention falls within the technical sector of personal protective equipment (PPE), more specifically in relation to the 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; hygienic-sanitary sector of any field, work, educational and domestic and in some models it contributes a germicidal power and inhibitor of toxicity 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 and has a possible medical application both to facilitate the work of health personnel as well as for patient treatment.

STATE OF THE ART

The use of air as a means of disinfection, detoxification and as a barrier against pathogens and viruses is becoming evident in 2020/21 after the pandemic suffered.

Objectives pursued:

(A) prevent impurities or contaminants from entering directly or indirectly into the respiratory tract, through the eyes, mucous membranes, through the skin or through the wounds of the user.

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

(C) Facilitate the application of treatments;

In the first situation, filtered air flow devices are used in an environment where the air contains particles harmful to health. FFP masks are included in this scope.

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.

We usually see that the seal between the mask and the house is defective, so the strategic aspiration of the device prevents the dispersion of harmful particles.

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 a lower level of protection is obviously 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 made of spongy material and in a single molded piece, which constitutes a kind of bowl. that adapts to the aforementioned facial area and that is also fixed to the user's head by any appropriate means.

A large part of the masks used by citizens are not approved and in other cases are expired; the device defended in this memory in these cases reduces contagion.

Filter masks [filtenng-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 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 pollutant; They have an added polarity that decreases with use and humidity and the device in question increases the shelf life.

On certain occasions, the user usually wears the mask on the chin, on the forehead, on the elbow, in a bar, smoking as an example, so it is not bad to have a more bearable resource

COVID-19-like diseases are spread mainly from person to person through droplets that are thrown from the nose or mouth of an infected person when coughing, sneezing or talking. These droplets are relatively heavy, do not go very far, and fall quickly to the ground. A person can get COVID 19 if they breathe in droplets from a person infected with the virus. That is why it is important to stay at least two meters away from others. These droplets can land on objects and surfaces around the person, such as tables, knobs, and railings, so other people can become infected if they touch those objects or surfaces and then touch their eyes, nose, or mouth. For this reason, it is important to wash your hands frequently with soap and water or an alcohol-based disinfectant; The invention in some models prevents droplets from remaining on the user's face or on the mask itself.

The novelty of the invention object of this application is that it incorporates a filtered air screen curtain and an air sweep that protects the user. The idea arises from the need to keep pathogens out of the mask when eating, drinking, talking or smoking, reducing the chances of infection and promoting activity restoration work, entertainment venues, concerts, sports events, sports activities, transport (plane, subway, taxi, buses).

The applicant does not know of any solution (apart from other inventions of his own that are in the process of being processed) that can be considered similar to the invention since he has only found utility models that include only air diffusion, some of which create a air flow from the user to the surroundings, causing a concentration of pathogens around those who do not have them, this concept / result being highly unsupportive. This does not happen when air expulsion is combined with suction and the protected areas are dimensioned to a minimum thanks to the use of windows and a 2D or 3D dispenser / suction framework. Another achievement of the invention is to keep the concentration of substances and ions high in the areas that we are interested in protecting, since the suction prevents excessive dispersion and by sizing and timing it in a balanced way, it is avoided to create a dangerous flow of pathogens towards the Username.

The only files found that use the air with external fan are ES-2778000_A1 and ES-2797248_A1

MODES OF EMBODIMENT OF THE INVENTION

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

There are usually two air circuits where there may be a means of disinfection.

Open circuit: from air intake, filters, propeller drive motor and

ducts and ejection holes (figure 1).

Closed circuit: from expelled air holes, suction holes,

filters,, propeller drive motor and ejection ports and ducts.

(figure 2)

There may be a single motor that drives the two circuits by a two-screw mechanism or two or more motors, at least one for each circuit.

In view of the figures and in accordance with the numbering adopted therein, some non-limiting examples of embodiment of the suction dispensing device of a filtered air flow can be observed.

The recommended device is structured from a body (1), which in this case forms a network that configures a polyhedral, which can also be of the bowl or hemispherical type, for example. The body represents a chassis or support structure (1) that houses a plurality of holes or slots (2) in charge of expelling (2a), others of sucking the air (2b) already filtered by filters (3a) arranged in the support (1); There is a filter at the level of the air intake of at least one fan or air pump (3) located on the support (1), other filters are between the suction ducts and a motor (3m) with propellers (3h) of impulsion. The fan or air pump (3) is powered by a battery powered by an electrical connection, micro-USB type or equivalent, located on the support structure (1). The body (1) is attached to the face, completely covering the hygienic, surgical or FFP2 mask, which in turn protects the mouth and nose and remains completely adhered to the skin and stabilized by the pressure exerted by one or more elastic cords that surround the head. or the ears, obtaining an optimal seal (perfect if possible).

The filtered and diffused air through the dispenser orifices covers the area and is kept around by having a suction through the suction holes which are strategically arranged to maintain a curtain of filtered air around the mask and are also installed in areas where air leaks (which may contain pathogens) are more likely to be around the entire outer perimeter of the mask and particularly from the sides and near the nose.

In the body (1) a respiratory window (2) is fixed.

As an exclusive novelty, the window (5) has a filtered air curtain-screen (4) that prevents the entry of polluted air. Filtered air is drawn in through of a motor with propellers, and passes through some lower ducts ((2c) that reach one side of the front window (5) of the mask and is sucked through the converging ducts (2d) on the opposite side of the window (5) front (other models may also include holes on the lateral sides or different combinations between the exhaust and suction holes) and return to an internal filter (3a). This system forms a closed circuit of filtered air. In this closed circuit the air, after If filtered, it can be enriched with bactericidal and antiviral substances (essential oils) or by ions that destroy viruses, bacteria and pathogens without being harmful to the user.

Any method can be used to improve the capabilities (bactericidal, virus inactivator and pathogens) of the air curtain-screen (4). The combinations according to aerodynamic criteria are multiple, and it will facilitate the isolation between relatives with excess occupation in a house.

Its use in places that allow recharging ensures an influx of public (bars, theaters, cinemas, stadiums, airplanes, trains, public transport etc.)

Figure 7 shows an embodiment of glasses that comprise the filtered air screen (4) described for the mask of Figure 6. It comprises a motor (2m) with propellers (2h), and passes through lower ducts (2c ) that reach the lower side of the glasses and is sucked in by the convergent ducts (2d) on the upper side and return to an internal filter (3a). This system also 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.

Figure 8 shows an embodiment of a cap with a diffuser, also with its filtered air curtain-screen (4).

The masks that are the object of this application may have different joints, fittings and closures, always respecting the objectives of this utility model. The essential nature of this invention is not altered by variations in materials, shape, size and dimensions and arrangement of the component elements, described in a non-limiting manner, this being sufficient to proceed with its reproduction. In general, any other detail, accessory or secondary, will be susceptible to variation as long as it does not alter, change or modify the essentiality of the invention.
