Abstract

The invention concerns anti-pollution masks comprising one shell, simply for breathing, or with two insulating filtering shells for integrally protecting the eyes, nose and mouth. These masks are adapted to protect against risks: one-shell masks for "walking about"; two-shell masks with reinforced filters for professionals, who by the nature of their work are exposed to aggressive pollution, or suffer from respiratory disorders or deficiency. The stroller's masks with one shell, bored with holes, comprise an external anti-particle and anti-gas veil, as well as an internal gasproof, dustproof, acid rainproof and bactericide filter. The masks for professionals comprise two shells: the external shell, fireproof comprises an external anti-particle and anti-gas veiling, and an internal filter (F'). A second filter (F'') is fixed externally to the internal shell, it is also bored with fine staggered holes opposite those of the external shell. The invention also concerns external veils, internal filters consisting of N vertical screens pre-impregnated with natural products or chemical disinfectants, or fragrant oils. The invention further concerns similar breathing masks, adapted to animal morphology, for dogs and horses.

Description

ANTI-POLLUTION MASKS
against DUST, PARTICLES,
HARMFUL GAS, ACID RAIN and BACTERIA
DESCRIPTION
10) Technical field of the invention
- The present invention relates to various kinds and types of anti-pollution respiratory masks, pre-molded for parts, for people and for certain animals.

 - These masks intended for people come in several sizes adapted to the faces of a child, a teenager, an adult ..., designed and made to ensure their protection against all kinds of pollution: dust, particles, harmful gases, acid rain and bacteria. They come in two main types: strictly respiratory masks isolating only the nose and mouth poly-protective masks including the eyes, nose and mouth of the user, when eye protection is deemed necessary by the medical staff, the designer of this type of mask is responsible for preserving sight and vision in the wearer.

 - The invention also makes it possible to produce such masks adapted to the morphology of certain animals such as dogs and horses, but only of the respiratory type protecting only the nose and the mouth of our friends; for the dog for example, in the form of a mask which can be accommodated inside an existing type of muzzle by choosing it to be wide and enclosing; the horse mask must be flexible, robust and extendable under the chin guard, to allow the courier to breathe with his mouth wide open as usual.

 - These masks are designed and must be produced with the aim of respecting the effectiveness of anti-pollution protection; the aesthetics of the device; the ceilings of costs, and therefore of selling prices to the public, industrial production in very large quantities should make them economically accessible to all citizens.

2 ") Indication of technical qnFçrie * .Res implemented
- The gas masks made their massive appearance during the First War
World, to protect the military during gas attacks.

 - During the Second World Conflict, in France in any case, Passive Defense provided for the civilian population. These gas masks included a filter cartridge. Protecting the entire face of the wearer, they were particularly unsightly but essential.

 - Currently, a protective mask called "Hygiene mask for routine work" is marketed to the public. According to Figure 1, this mask stops only large particles larger than 5 pm, such as household dust, pollens, or dust and particles from which suffer, for example the plasterer or mason worker at work. We reproduce the mention in several languages appearing on one of its packaging, by 4 pieces, under the brand Triplex. Under the same brand, a model N "918 is also dustproof only. There is also an interchangeable cartridge mask N" 925, not found on the market, so we had to request documentation at the address of TRIPLEX in Paris. .

This is possibly what made a Professor of the C.N.R.S., during a very recent television intervention, "that there would be no civilian gas masks". We will come back to it. Thus, the whole of the majority urban population is victim of multifaceted pollution, starting with that of these cities whose air is the most polluted - in France: Marseille, Dijon, Montpellier, Lyon, Paris, La Rochelle, Nantes (these last two cities yet open to the sea winds), Crerioble, Amiens. But even a city of 15,000 inhabitants can be very polluted between 5 and 6 pm, at least such a crossroads or such a busy avenue.

- worldwide: Athens, Bankok, Bombay, Calcutta, Budapest, Krakow, Delhi,
Jakarta, Beijing, Seoul, Shanghai; and Karachi, Cairo, Los Angeles; and MEXICO, the most polluted capital in the world. Leipzig is not included: reunification must have benefited him ...

- This list proves in any case how this scourge affects both cities of member countries of the G7 and those of developing countries. And that the solutions are urgent.

- This air pollution has two sources: factories and motor vehicles.

- The factories allow to escape: chlorofluorocarbons (C.F.C.), freons of hydrocarbons, butane, propane and the residues of the same due to incomplete combustion ...; krypton (nuclear power plants); SO ', sulfur dioxide, from the combustion of fuel oil and coal; H2S, toxic and foul-smelling sulfur dioxide; CO ', carbon dioxide; mercaptans, including methanethiol and ethanethiol, which emit foul odors; and acid rain charged with acetic, formic acids, SO H '(sulfuric acid), NO'H' (nitric acid); but also fluorine, lead and asbestos ...

- Motor vehicles running on petrol, give us carbon monoxide CO, a very dangerous odorless gas, deadly in high concentration; benzopyrenes and benzofluoranthrens, known to be carcinogenic.

- Motor vehicles fitted with diesel engines are the largest mobile emitters of carbon particles, loaded with oily substances. But they also exhale nitrogen oxide; H2S already mentioned; NO2 nitrogen dioxide; CO '; and SO 'sulfur dioxide, etc ...

- In short, the urgency of having atmospheric ii'asqu nStii-nallaltions is therefore of humanitarian connotation since the catalytic exhaust pipes will only reduce automobile pollution, but will have no effect on industrial pollution ... whose disappearance is not for tomorrow.

- We will dispute the solution brought by the respiratory mask to air pollution. Certainly the argument of unsightly will be brandished. But if no one thinks of making the wearing of such masks compulsory, citizens who suffer from this pollution and those who put their health before the virtue of elegance must be able to obtain an anti-pollution mask. All the more flexibly and without complex that the wearing of such masks can be limited to the time taken to cross zones with heavy pollution during peak hours.

 All the more easily as a personal badge for detecting the rate of air pollution will soon be marketed, this sensitive badge allowing each pedestrian, each transported person, to judge when he / she should put on his mask and where he will become optional again ...

- It is about all this that the media must inform the public objectively, without excluding the budget for the information campaign decided by such and such.
State, in proportion to the responsibilities it would recognize in the undeniable deterioration of atmospheric conditions for thirty years.

Presentation
A) Regarding people, two kinds of masks will be made
- a kind of anti-pollution masks called traffic: economical because it includes a single respiratory protection shell; this kind of masks differentiating into two types
* a type of strictly respiratory protective mask M.mono.R., the
shell n1 encompassing only the subject's nose and mouth, and the convexity of the shell always leaving a space between its internal wall and the face of the user.

* a type of circulation mask with a single shell but protective
integral (M.mono.Intégr.), therefore encompassing the subject's eyes, nose and mouth, the domed shell always respecting a free space between its wall and the person's face.

- and a kind of professional mask, with two protective shells; this kind of masks, also
* a type of professional mask with two shells (M.duo.R.) therefore strict
respiratory because it isolates only the nose and mouth of the user.

* and a type of professional mask (M.duo.Intégr.), with two shells,
therefore isolating the subject's eyes, nose and mouth - Always without ever "sticking to the face".

- These two types of masks are suitable not only for people exposed to heavy pollution in the exercise of their profession, but they are essential for people suffering from cardiac or pulmonary diseases, such as those victims of respiratory insufficiency or cardiac dysfunctions. .

As for their fixing and their retention in place, these four types of masks, two so-called circulation, two so-called professional, are all provided with a strong elastic strap (B), a width of one centimeter, adjustable tension , coming to pass above the ears, between the skull and the two auricular pavilions, and enclosing the subject's head so as to make the joint (JS) adhere softly, all around, to the face of the user or carrier, essential condition for the effectiveness of these devices, particularly in children and adolescents.

Description of these two kinds of masks for people
- Monocoque masks: (M.mono.R.) and (M.mono.Intégr.), The R. = respiratory protecting only the subject's nose and mouth; and Integr. "integral polyprotector" isolating eyes, nose and mouth.

- They have in common, according to Figures 2 and 3, a single rigid plastic shell pierced with fine air intake orifices, orifices well distributed over the entire surface of the shell, except over its entire periphery since ct is on this intact strip that the Veil (V) will adhere to the outside of the shell, and the filter (F) inside said shell, so that none of the orifices allowing inspiration and expiration of air by the user, is not blocked by the adhesive of the Veil, nor by that of the Filter. In addition, the mounting of their monohull is identical: over its entire periphery, each monohull is inserted into the groove of the Flexible Joint (JS) which is strongly glued to the hull, this JS joint being calculated to adhere perfectly, on all around, to the epidermis of the user, which the flange (B) that we have described above, contributes effectively, as according to Figure 8 for example.

- In addition, another common point, the monohulls of (M.mono.R.) and of (M.mono.Intégr.) Are similarly equipped
* an external veil (V), with two fine fabrics, ie a canvas folded over, including a compressed wadding, forming a vertical screen sewn over its entire perimeter, then impregnated by maceration in a slightly oily essence loaded with powder of charcoal act. This Veil (V) is anti-particle and anti-gas. Being made adhesive only on the entire periphery of one of its faces, this veil (V) will adhere by its periphery to the outside of the monohull and completely cover it without closing any orifice cf. Figure 9.

* a filter (F) with multiple screens (5 or more), each of these screens towards tieaUx composing this filter, being previously impregnated by maceration in a special bath varying from one screen to another, and loaded with products anti-particles, anti-gas, anti-acid bases, bactericides and odoriferous, the following details, only as examples
- the first vertical screen of good canvas with a very tight weft, closest to the shell, will first be impregnated with an iodized solution, then coated with officinal active vegetable charcoal powder which will be fixed to the fabric by an aromatic essence oily, for example based on rosemary,
- the second vertical support of a tightly woven fabric, will fold over a thin pad of compressed cotton wool, the whole being impregnated with chlorophyll and a powder of vegetable charcoal of active eucalyptus officinalis, powder fixed by a solution slightly savory oily,
- the third vertical screen e. tight canvas, attached to the second, will receive a dilution of chemical bases, therefore chemically anti-acid, charged with powdered vegetable charcoal with bay laurel fixed by an aromatic essence of juniper berries, for example,
- the fourth screen of fine canvas, joined with the third, will be coated with oily essences of thyme, sage, eucalyptus and pine bud, all antiseptics and bactericides,
- the fifth screen will have been impregnated with slightly oily aromatic essences with lavender, hawthorn, violet, rose, for example. It is this fifth vertical canvas, sewn to the other four only over their entire perimeter, except for a point here and there, which will be closest to the face of our mask wearer; while it is the first screen, which will be made adhesive on its entire periphery only, which will fix the filter (F) -to-five-screens on the internal face of the monocoque - cf. Figure 9. This adhesion system on the sole periphery of the filter (F), like veil V, makes them easily replaceable, as soon as respiratory discomfort proves that they are soiled and blocked by particles.

- Now, what differentiates (M.mono.R.) from (M.mono.Intégr.) Is obviously that the shell of M.mono.Intégr., Will include the eyebrows of the person, leaning on her forehead since she has to protect her eyes, so this monocoque will have two neutral optical glasses, hermetically crimped in the mask shell to ensure the view and vision of the user.

- As for the glasses wearers, they will wedge them in the light groove pre-molded in the monocoque slightly below the birth of the nose, the stability of the said glasses being ensured thanks to the two sliding clamps fixed to the clamp (B) for fixing the mask, which immobilize each branch of glasses in its proper position.

 Masks with two shells: M.duo.R. (nose and mouth only), and M.duo.Intégr.

 (eyes, nose and mouth), so-called professional anti-pollution masks, they are also available in these two types of device, 'according to Figure 9.

- These two types of masks consist of an external rigid shell (C.1 ext.), Molded in fireproof material, pierced with fine orifices over its entire surface, except on a peripheral margin where the veil (V) will adhere to the 'exterior and filter (F) (only one filter) or (F') (if two filters (F ') and (F ")), inside this outer shell, so as not to block any of the orifices ; and an internal rigid shell (C.2 int.) not fireproof, also pierced with fine orifices for transits of the air inspired then exhaled by the subject, these orifices being arranged in such a way that when these two shells C .1 and C.2 are embedded, C.1 on: above C.2, each in its groove in the end piece (Emb), the holes of the internal shell (C.2 int.) Are not found not opposite, but staggered in relation to their counterparts in the outer shell (C.1 ext.).

- These two shells, external and internal of the same mask, are manufactured continuously nestable, especially their respective <contours and are inserted C.1 ext. above C.2 int. each in its groove, the two grooves being formed in the single end piece (Emb.) robust and flexible, where they will be locked each in its groove. This is explained in Figure 7, which also highlights the flexible joint (JS), either glued to the heel of this tip, or part of said mask tip if it could be molded with it to form that only one element end piece-joint-flexible, the goal to be obtained to obtain that the joint (JS) softly and hermetically fits the volume of the face to be protected without damaging or irritating an epidermis without problems.

- All that has been specified above concerning the anti-pollution equipment of monocoque masks, applies similarly to masks comprising two shells, called professional, but not identically
- the anti-particle and anti-gas veil (V), outside the external shell (C.1 ext.), but the products that permeate it must be reinforced, due to the heaviest pollution to be faced ,
- each filter may or must have more screens and the products, powders, oily essences, chemical bases, disinfectant elements must allow the user to deal with professional pollution of all origins.

 - for these same reasons these so-called professional masks will no longer include only the external veil (V), and a single internal filter (F), but the Veil (V) and two filters (F ') and (F ") - cf. Figure 9, the filter F 'adhering under the outer shell (C.1 ext.), And the filter F being arranged outside the inner shell (C.2 int.), So that the two filters s between the two shells, without touching each other (!) because any kind of pad that is too thick is excluded, so that the user can breathe normally ...

- Of course the double-shell protective mask, in its full protection version: (M.duo.Intégr.) Places its flexible joint (JS) above the subject's eyebrows, so it too has two neutral optical glasses ensuring sight and vision to its user.

- And the double-shell masks naturally include the slight groove allowing the base of the glasses to be wedged; as their fixing flange (B) helps, by its two lateral clamps to secure each branch of glasses to its correct position.

Manufacturing precautions - Such masks must prove to be completely safe, which will require a constant effort to improve and adapt the anti-particle sails (V), and, even more, that of the filters (F). To begin with the development in these two functions, before any marketing of these masks.

- It will therefore be incumbent on any manufacturer of such masks of all types to submit them to reliability tests in "real situations". Indeed, heavy metal particles, dust, of course, but even more gases, acid suspensions are so diverse, so numerous and reactive with each other, even able to combine with disinfectants or fixatives impregnating Veil and filters ..., that the remedies should not be worse than the disease! -Primum, non nocere - It will therefore be essential to organize laboratory tests using polluted air taken from factories which are known to be polluting as well as during peak hours in Montpellier, Paris, Milan, Mexico City.

- In the laboratory, these polluted air samples will be sucked up by these existing machines, used to analyze the films of cigarettes, fitted with the masks that are the subject of this patent application. These machines sucking air like a person, will prove what will pass through such a mask, like the harmful suspensions which will have been stopped.

- These tests will determine which products should be impregnated with the Veil (V) and the N screens of the filter (F), filters (F ') and (F "), to fill the said masks.

- Indeed, being so complex data, pollutions to this point harmful, Research must first achieve the desired result, both from the health point of view as technical and commercial loyalty.

- We add that in our opinion, no disinfectant or neutralizing agent capable of impregnating the veil (V) or a filter (F) should be eliminated in principle, even if it seems at risk. We will cite, in addition to the purifying compositions recommended above for soaking the veil and screens of a filter: formalin; chlorine; ethylene oxide; phenols and chlorophenols; cresylols; copper and iron sulfates; potassium permanganate; tincture of iodine hydrogen peroxide; ozone, this powerful disinfectant; chloramine ..., because we know, since Samuel HAHNEMANN (1.755 - 1.843), founder of Homeopathy, that, by successive dilutions, such an aggressive element in the pure state can, diluted, even
very diluted, help restore such balance without harming the patient.

Presentation and packaging of anti-pollution monohulls or in pairs
shells: each mask, intended for children, adolescents or adults, will be
delivered complete, assembled and assembled, provided with its veil (V) and its filter (F) or
its filters (F ') and (F "), its flange (B) and its flange attachments.
filters and the veil must adhere to the support shell; each mask as well
equipped will be bagged in a hermetically sealed plastic bag.

- In addition, each unit packaging will include
- instructions for use and assembly, supporting drawings,
- three spare anti-particle and anti-gas sails (V); three filters
(F), or 3 filters (F ') + 3 filters (F "), each section in plas
machine welded tick,
- as well as a tube of anti-inflammatory and antimycotic ointment, of which
optionally coat the perimeter of the flexible contact seal (JS), if
the buyer feels the need to avoid irritation (people
sensitive; child prone to allergies; temporarily assigned user
dermatitis).

- THE ESSENTIAL of such masks, in particular those intended for children, must
be improved, by offering a choice of external shells reminding, by simple
impression. light 'on the Veil (V), a fawn, a mouse, a squirrel, a turtle ...
in order to make them attractive, because it is often children who have
far away, you no longer need to wear such masks ...

B) Masks for animals
- Of a strictly respiratory type, they will be designed and produced according to. the reviews of M.mono.R. devices and M.duo.R. It will suffice to adapt the shape of these
masks the morphology of each animal,
Figures lO-- -: show that the mask can be used for dogs in
covering it with an enveloping leather muzzle, which prohibits the animal from
scratch, or even tear off "his" mask. However, the chosen museliere,
the existing one (s) will have to be one or two sizes above to resolve
the insertion of said mask into the protective muzzle.

- Figures ll - r-show that the use of the respiratory mask is all
also possible in the case of a horse, provided that the lower part of a
such mask be widened and softened to allow the dear
