 DETAILED DESCRIPTION OF THE DRAWINGS
In the various figures, like references denote identical or similar elements.
A first exemplary embodiment of the mask according to the invention is shown in FIG. 1.
In FIG. 1, a user 1, in this case a civil airplane pilot, is wearing a respiratory protection mask 2, in this case a quick-fitting mask. This mask 2 includes an oronasal face piece 10 and a semi-flexible lip 6. A pipe 3 conveying a respiratory gas supplies the mask 2 with respiratory gas from a respiratory source 5. This pipe 3 is connected in a fluid manner to the oronasal face piece 10. Removable hygienic protection system 4 (which may also be referred to as a “hygienic protection means” at some parts throughout this application), in this case a filter, is placed by the pilot inside the mask 2, for example when he takes his seat in the airplane. This hygienic protection system is made up of at least two main parts 4a and 4b. The first part 4a filters the air breathed out and prevents any infection from penetrating inside the mask, and in particular in a microphone or inspiratory 8 and/or expiratory 9 valves. The first part 4a for example if made of a paper impregnated with an antibiotic, bactericidal or other substance. First part 4a may also be referred to as a filter part 4a. The second part 4b is made of a flexible and airtight material, such as silicone or latex, for example, and is used to secure the hygienic protection system 4 inside the mask 2, and maintain the seal of the hygienic protection system 4 within the mask 2 by contact between this second part 4b and the inside of the semi-flexible lip 6. Second part 4b may also be referred to as lip securing part 4b. If necessary, a cord 7 is fixed to the hygienic protection system 4 to facilitate its extraction from the mask 2.
According to a variant, illustrated by FIG. 2, a third part 4c, forming a thin lip element, prolongs the part 4b and extends beyond the semi-flexible lip element 6 by a few millimeters to make the mask 2 more comfortable to wear and to improve the seal between the hygienic protection system 4 and face of the user 1. Third part 4c may also be referred to as lip insulation part 4c. This part 4c is, for example, also made of silicone or latex, but is thinner than the part 4b.
According to another variant, illustrated by FIG. 3, a fourth part 4d, also forming a thin lip element, prolongs the third part 4c so as to at least partly cover the outer surface of the semi-flexible lip 6. This part 4d also provides a hygienic protection function. It can also be made of silicone or latex like the part 4c. Fourth part 4d may also be referred to as lip extension part 4d.
According to yet another variant, illustrated by FIG. 4, the part 4a has a corrugated shape, with corrugations substantially centered inside the mask 2 and/or the inspiratory valve 8, in order to reduce the pressure drop and/or facilitate the handling and/or extraction and replacement of the hygienic protection means 4.
A second exemplary embodiment of the mask according to the invention is shown in FIGS. 5 and 6.
According to this second embodiment, the mask 2 according to the invention includes an oronasal face piece, a semi-flexible lip element and fluid connection means similar to those of the embodiment described above. FIG. 5 more particularly represents the semi-flexible lip element 6, the edge 11 of which, intended to be in contact with the face of a user, is covered by hygienic protection means 4. This edge returns toward the center and the interior of the mask 2, forming an internal groove 12.
FIG. 6 mainly represents this edge 11 of the semi-flexible lip element 6. The hygienic protection means 4, in this case a thin film, includes:
    • a part 4c which insulates the semi-flexible lip element 6 from the skin P of the user 1,
    • another, so-called structural, part 4b, which rests in the hollow of the semi-flexible lip element 6, preventing the hygienic protection means 4 from coming away from the mask 2, and
    • yet another part 4b′, placed outside the mask 2, preventing the hygienic protection means 4 from entering into the mask 2 when it is used and if possibly including an elastic thread 13 gripping the semi-flexible lip element 6.
The part 4c which insulates the semi-flexible lip element 6 from the skin P of the user 1 is placed all around this semi-flexible lip element 6. It is placed on the external part of the semi-flexible lip element 6, but, possibly, also over a large portion of its internal part. This part 4c is made of silicone, latex or a fibrous or woven material, for example.
The so-called structural part 4b is more rigid than the part 4c. It is, for example, made of silicone or latex. It has a shape designed to fit inside the internal groove 12 of the semi-flexible lip element 6. It provides for stable positioning of the hygienic protection means 4, preventing them from coming away from the mask 2 while the latter is being used.
The last part 4b′, the one possibly including an elastic thread 13, is fixed all around the outer perimeter of the hygienic protection system 4 in order to keep it stably positioned by preventing it from re-entering into the mask 2 while it is being used. This part 4b′ can be made of silicone or latex, for example. Part 4b′ may also be referred to as lip securing part 4b′.
This architecture takes into account the possible elastic distortions of the mask 2, of the structural part 4b and of the possible thread 13, so that the assembly comprising the hygienic protection means 4, the structural part 4b and the possible elastic thread 13, can easily be replaced after each use.
According to a variant, a flexible structure is placed between the hygienic protection means 4 and an internal part of the semi-flexible lip element 6. This flexible structure, such as a thin film of silicone or latex, for example, extends beyond the semi-flexible lip element 6. In place of or in addition to this flexible structure, another flexible structure, such as a thin film, can be placed outside the hygienic protection means 4, inside the semi-flexible lip element 6 and extending beyond the latter.
A third exemplary embodiment of the mask according to the invention is represented in FIG. 7.
As for the embodiments described previously, this third embodiment of the mask 2 according to the invention includes an oronasal face piece, a semi-flexible lip element and fluid connection means similar to those described above.
FIG. 7 more particularly represents the semi-flexible lip element 6, the edge 11 of which, intended to be in contact with the face of a user, is provided with hygienic protection means 4. This edge 11 returns toward the center and the interior of the mask 2, forming an internal groove 12.
In this example, the hygienic protection means 4 are mainly placed outside the semi-flexible lip element 6. The hygienic protection means 4 mainly comprise a thin film which surrounds the semi-flexible lip element 6 on the outside. The intrinsic elasticity of this thin film enables it to be placed easily around the semi-flexible lip element 6. This thin film is, for example, made of silicone or latex.
The hygienic protection means 4 comprise three parts:
    • a part 4b′ on which the thin film is pulled against the semi-flexible lip element 6; this area can be strengthened by a reinforcing structure consisting of an elastic thread 13 incorporated in the thin film; this particular arrangement allows the thin film to be replaced easily and firmly presses it on the outside of the semi-flexible lip element 6 by creating a pressure PM providing the seal between the thin film and the semi-flexible lip element 6; the elastic characteristics of the assembly comprising the thin film and the reinforcing structure are chosen so that the pressure PM exerted is greater than the relative pressure PA of the air contained inside the mask 2, but without being too great to avoid significantly distorting the semi-flexible lip element 6;
    • a part 4c placed between the skin P and the semi-flexible lip element 6 which forms a hygienic protection; and
    • a part 4d extending beyond the semi-flexible lip element 6; this part is very flexible, is used to follow the contours of the skin P and any folds in it and thus provide the seal between the skin P and the thin film.
This thin film therefore provides a seal that is significantly better than the masks of the prior art.
The hygienic protection means described above are particularly economical, making their use and their regular replacement less costly.
The hygienic protection means can be stored in a sealed, sterile and possibly transparent plastic bag, also including disinfecting wipes. When the pilot is preparing his mask before a flight, he can therefore also clean the lips of the mask and of the visor before replacing the mask in the mask box.
