DESCRIPTION

Face shield

TECHNICAL SECTOR

The present application refers to a face shield, which serves to prevent saliva or mucus exits and entrances, from or towards the user's mouth or nose. It is applicable in the field of personal biological protection measures.

STATE OF THE ART

In situations of diseases that can be transmitted by saliva or nasal mucus, it is necessary to have health protection measures to avoid contagion, the mask being the most widespread in use but of little effectiveness given its short protection in time (few hours) .

The microorganisms that leave our body through the mouth and nose adhere to it, being trapped in it. This means that touching the mask with the hand to reposition or remove it, whether to drink water, eat, smoke or breathe fresh air, implies contagion from the mask to the hand with the consequent danger of transmission. And hand in hand we can pass it to any surface or person.

There are two types of masks, those that protect against infecting and being infected, and those that protect against infecting. That is, in the sense of exhalation and in the sense of inhalation.

In our case, we would be protected in both directions since microorganisms cannot pass through the material that is the main element of the protector, and it perfectly covers the nose and mouth.

In general, protection measures are limited to preventing the user from infecting other people. To do this, there are barriers that capture any aerosol or particle that it emits and that may carry infectious agents. In our case, the protector, when it is made of PVC, is capable of retaining static energy so that the aerosols are attracted to it like a magnet, being trapped in the protector, the protector can often be disinfected with cotton and alcohol 96 to continue its use after a few seconds until the alcohol evaporates.

All masks or face shields are complex and expensive to manufacture, so supplies sometimes break down, especially in the event of a pandemic.

The applicant does not know of any face shield that can solve these problems.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a face shield according to the first claim. Its different variants solve the problems outlined.

It is a very practical idea since it allows us to block the viruses and bacteria that we expel through the mouth and nose, as would any surface placed in front of the nose or mouth. Being charged with static energy, it retains aerosols (microparticles of saliva or nasal mucus) that are emitted as if it were a magnet. It can be complemented with sheets with UV radiation filter and sheets with antibacterial treatment. It can be transparent so it does not prevent non-verbal communication at all, thus being of great help for people with hearing disabilities since they can continue to read the lips of other people who wear this protector.

By not touching the skin there is no risk of skin infections, unlike with conventional masks that within a few hours are plagued with staphylococci and streptococci, among other bacteria, in addition to the air flow that we breathe in and expire enters through the edge of the protector, Being this air always fresh, never stale air, so it is suitable for sports since we will not lack oxygen.

The preferred method of fastening is through any glasses in such a way that it has inserts at both ends of the body that are configured for the passage of the temples and is perfectly positioned in front of the nose and mouth, the user must then take off the goggles to take off the shield to drink water from a glass or eat or smoke. Will not be It is necessary to remove the protector to drink water from a bottle as the protector folds enough so that the neck of the bottle enters from the side to the mouth.

The protector itself is also an advertising tool, and can be easily personalized by laser printing, logos, graphic designs or even phrases or any type of text.

The face shield / aerosol blocker is the type that covers the buccal area. It is made up of a printable sheet with the central body covering, at least, the nose and mouth. The central body has two symmetrical arms in its upper half finished in two ends configured for the passage of the temples of any type of glasses.

Other variants can be seen in the rest of the report.

MODES OF EMBODIMENT OF THE INVENTION

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

An example of an embodiment is shown in figure 1. It is a face shield with a laminar structural configuration with an axis of symmetry that, in use, will remain approximately vertical. The protector comprises a central body (1) of relatively great width to cover the nose, the mouth and all the necessary surface of the face below the eyes.

The central body (1) has two symmetrical arms (2) in its upper half. The arms (2) are finished at two ends (3) slotted for the passage of some temples (4) of glasses. The ends (3) therefore have an orientation approximately horizontal or perpendicular to the axis of symmetry, the grooves (5) being approximately parallel to it (± 25 °), converging towards the lower part of the mask. The grooves (5) can be enlarged or replaced by holes if the pins (4) are too thick to pass through. Not reaching the perimeter so as not to weaken the ends (3). A vertical cut (6) divides the lower part of the central body (1) into two symmetrical wings. These wings overlap each other to give the guard the chin shape. In figure 1 a way of coupling the wings to each other is shown. A flange (7) in the shape of a triangle or semicircle fits into an incision (8) in the opposite wing. The incision (8) can be straight, triangular ... and generally several incisions (8) are presented to adjust to the different sizes or to vary the angle of the lower part and better close the aerosol outlet downwards.

In a second embodiment, the ends (3) are not slotted but comprise a fixing formed by a flexible strip (9) that can hug the corresponding lug (4). For example, the flexible strip (9) can be made of silicone.

The flexible strip (9) can form a tube to be traversed by the lug (4). However, it is preferred that it comprise removable fasteners at one end to undo that tube and clamp or release the leg (Figures 5 and 6). For example, the flexible strip (9) may have Velcro (registered trademark) at its end or other similar attachment, including tabs and grooves or incisions.

In case the protector is excessively long for the face, it can be shortened. The vertical cut (6) is lengthened by the necessary millimeters and, following the same shape of the lower contour, cut the same thickness of millimeters from the lower edge. In this way the protector can be easily adapted to different sizes.

It can be seen, especially in figure 2, how a convex projection is arranged between the arms (2) to cover the bridge of the nose.

As an emergency measure, the template can be printed directly on paper or cardboard in order to have an effective protector for a few minutes or a few hours.

The sheet, preferably made of transparent PVC, can be accompanied by others with different treatments, such as a filter for UV radiation, anti-bacteria treatments, etc.

In addition, its use as an advertising element is of great value since the logos, _{brands or drawings printed on the mask will appear levitating in front of the} user's face, thus giving rise to a multitude of photographs on social networks with the logos of the sponsoring brands.
