Description

DESCRIPTION

Mask with UV sterilization

Technical object of the invention

The present invention refers to a mask of those used by people in general, in order to protect themselves or to protect other people from possible polluting emissions, which has the particularity of being equipped with an ultraviolet ray emitting device that does not it only keeps it continuously sterilized for the benefit of the person who wears it, but also increases the protection of those close to it.

Technical sector to which the invention relates

The invention that is presented affects the Section of Current Needs of Life, of the International Patent Classification (CIP), in its section on Personal or Household Objects, chapter on Clothing and in the section on Health and Protection, chapter on Medical Sciences and Salvage.

From an industrial point of view, it affects the manufacture of pharmaceutical accessories for personal, surgical and health use.

Background of the invention

Currently there are mainly two types of masks. On the one hand there are surgical masks, which are used by professionals in operating rooms to filter the air that is exhaled containing particles, bacteria or viruses that can be transmitted, through breathing, to other people around us. .

On the other hand, there are respiratory protection masks, which filter the inhaled air from outside. These masks retain particles, bacteria or viruses from the environment in which we find ourselves. They are approved for different filtering capacities. Some incorporate an exhalation valve that reduces interior humidity, in order to provide more comfort in general and especially when breathing.

According to the protection of your filter, they are classified according to the following grades:

- FFP1: 78% filtration efficiency and 22% leakage to the outside. Protects from non-toxic and non-fibrogenic residues of dust or aerosols. Prevents nuisance odors from being inhaled.

- FFP2: 92% filtration efficiency and 8% leakage to the outside. Like the previous one, it offers protection against non-toxic residues and against fibrogenic residues. In this way, it prevents us from inhaling toxic fluids of dust, aerosols and fumes.

- FFP3: 98% filtration efficiency and 2% leakage to the outside. It works against different poisonous and toxic types of dust, smoke and aerosols. It is effective against bacteria, viruses, spores and fungi.

The World Health Organization (WHO) recommends the use of N95 masks that have a filtration efficiency of at least 95% for particles of 0.3 microns in diameter, with the FFP2 and FFP3 types being the ones with characteristics that are closest to the N95 that are suitable for medical facilities and first aid equipment because they protect against drops and aerosols when they are well adjusted on the face.

In view of the limitations that most of the usual masks present, either due to the filtration and leakage of external and internal agents, a personal protection mask is proposed in this document using technology that has existed since the 70-80s to the elimination and disinfection of microscopic pathogens, both on dry and aqueous surfaces such as water, air and soil.

The technology used is UV-c light (germicidal ultraviolet radiation) widely used in hospitals, laboratories and industry in general.

It is a futuristic mask that allows the elimination of bacteria, fungi and viruses through germicidal ultraviolet light radiation. When the user breathes, both in the inhalation and exhalation phases, the pathogens are automatically inhibited both in their multiplication and in the case of cells and fungi. In the case of viruses, it atrophies or breaks the DNA or RNA information that the viruses inject into the cells of the body, thus interrupting the diseases produced by those agents of few microns in diameter or even smaller.

The use of masks is common in the operating rooms of clinics, hospitals and health centers. Recently, due to the pandemic, a series of masks have been developed and registered in the Spanish Patent and Trademark Office that are specially designed for certain cases and circumstances in order to facilitate mobility and communication between people or simply to make it easier comfortable to wear for long periods of time.

By way of example, a few registered models are listed below which, having the same general purpose, have certain particular characteristics.

1 ES-1248111 U Protective sanitary mask

2 ES-1247899 U Oral, nasal or oro-nasal protection mask

3 ES-1247826 U Window mask for lip reading

4 ES-1248114 U Thermally conditioning mask

5 ES-1247683 U Germicidal filter mask

6 ES-1247062 U Equipment for disinfecting masks

7 U 202000318 Sterilizing mask holder

The first describes a mask suitable to fit with the rods of a spectacle frame, essentially characterized in that it is made up of a translucent, flat, flexible and landscape sheet, extended laterally with appendages whose ends fold over themselves to form a flange. It is specially designed to avoid fogging of glasses lenses.

The second describes a mask with filtering material, capable of being fixed on the user's mouth and / or on the nose, having an adhesive band that is placed on the user's skin.

The third refers to a mask that is especially suitable so that what the user is saying can be interpreted through the movement of their lips, for which it has a transparent window in the mouth area.

The fourth reference shows a solution in which the mask includes a material capable of being able to release heat or cold slowly after being subjected to heating or cooling.

In the fifth reference, a mask is described that covers the mouth and nose and has a particle filter, an emitter of ultraviolet radiation and a capsule that prevents radiation from going to the outside.

The sixth mentioned describes a device where the masks are placed for disinfection, including an infrared module with a heat emitter and an ultraviolet module with an ultraviolet emitter. It has temperature and time regulators. Finally, the seventh reference refers to an application document that describes a mask-holder box prepared for disinfection by means of ultraviolet radiation during the periods in which it is not used.

The sixth cited invention is the closest to the one now presented, although there are differences that represent a novelty in this new device.

The use of ultraviolet radiation, for sterilizing purposes, is known in general and is practiced in various applications throughout the world, being important to take into account the possible damage that can occur when directly receiving said radiation.

Summary description of the invention

As indicated at the beginning of the document, the invention refers to a mask used for medical and health purposes in order to protect itself and / or protect other people from possible transmitting emissions of contagions, which has the particularity to cover, like other masks, the nose and the face, including the chin of the user, extending back to also protect the sides of the face up to the ears.

The mask has front and side openings, to facilitate breathing, being covered with fine fabrics of tulle or similar. It has elastic fastening means, which fit behind the ears, or extend back to encircle the neck. As for the power supply, it is carried out from a large capacity and long-lasting battery that is placed in a pocket or preferably, in the arm where it is not uncomfortable or takes away mobility.

Its main characteristic is having a front chamber with a partition wall, close to the face, which acts as a support for sheets or strips of ultraviolet-ray emitting LEDs of a very specific wavelength. In this way, a curtain of rays is formed that eliminates bacteria, fungi and viruses in the two phases of respiration, that is, during inspiration and during exhalation, providing a very high degree of protection.

The radiation emitted is of the UV-c type with germicidal effects, which corresponds to the wavelength "c" of the three that exist in the ultraviolet range, situated between 200 and 300 nanometers (billionth of a meter).

It is directed forward, in order to avoid possible harm to the person, since this type of radiation, with all its advantages, also has serious disadvantages, being known Generally, the human body is prepared to defend itself from the damaging effect of the sun's rays thanks to the pigment known as melanin. This pigment has the property of absorbing UV radiation and when the body perceives damage from this type of light, it sends instructions to the affected cells, to avoid further damage, with the consequence of darkening the skin. (Tan effect). When exposure to radiation exceeds the absorption capacity of melanin, a toxic reaction occurs and burns and even the most serious of which is skin cancer.

The invention thus conceived has the following advantages:

- It is reusable, which represents an interesting saving

- It is long lasting

- Can be cleaned with alcohol

- It is always ready for use

- Allows you to breathe pure air, without germs

Schematic drawings are included below for a better understanding of the invention.
