Definitions

  • the present invention relates to respirator masks with hygienic protection.
  • the present invention relates to respirator face masks providing physiological protection, particularly for aircraft flight crew.
  • the invention relates, for example, to the respiratory protection masks used by civil airplane pilots to combat hypoxia in particular.
  • the protection masks for civil airplane pilots are part of the airplane and are used by several pilots in turn, particularly for tests or preventive uses of the masks. It will be understood that this causes a degree of physiological discomfort for the pilots and that it is not without risk concerning certain infections.
  • One object of the invention is to overcome at least some of the abovementioned drawbacks.
  • a respirator face mask providing physiological protection, particularly for aircraft flight crew, comprising:
  • the hygienic protection means are removable and can therefore be easily replaced between consecutive uses. This is made particularly possible by the second part which cooperates elastically with the semi-flexible lip element or the face piece. Besides the fact that this elastic cooperation facilitates the fitting of the hygienic protection means on the mask and their removal from the mask, it can, if necessary, be used to provide a degree of seal-tightness between the hygienic protection means and the semi-flexible lip element or the face piece.
  • FIG. 1 diagrammatically represents a vertical cross-section of a respiratory device comprising an example of a first embodiment of a mask according to the invention, worn by a user;
  • FIG. 2 diagrammatically represents, through a cross-section similar to that of FIG. 1 , a detail of a variant of the embodiment of FIG. 1 ;
  • FIG. 3 diagrammatically represents, through a cross-section similar to those of FIGS. 1 and 2 , a detail of another variant of the embodiment of FIG. 1 ;
  • FIG. 4 diagrammatically represents, through a cross-section similar to those of FIGS. 1 , 2 and 3 , a detail of yet another variant of the embodiment of FIG. 1 ;
  • FIG. 5 diagrammatically represents, in elevation, an example of a second embodiment of a mask according to the invention.
  • FIG. 6 diagrammatically represents, through a cross-section in the plane VI-VI of FIG. 5 , a detail of the embodiment of FIG. 5 ;
  • FIG. 7 diagrammatically represents, in horizontal cross section, an example of a third embodiment of a mask according to the invention, worn by a user.
  • FIG. 1 A first exemplary embodiment of the mask according to the invention is shown 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 4 a and 4 b.
  • the first part 4 a 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 4 a for example if made of a paper impregnated with an antibiotic, bactericidal or other substance.
  • First part 4 a may also be referred to as a filter part 4 a.
  • the second part 4 b 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 4 b and the inside of the semi-flexible lip 6 .
  • Second part 4 b may also be referred to as lip securing part 4 b.
  • a cord 7 is fixed to the hygienic protection system 4 to facilitate its extraction from the mask 2 .
  • a third part 4 c forming a thin lip element, prolongs the part 4 b 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 4 c may also be referred to as lip insulation part 4 c.
  • This part 4 c is, for example, also made of silicone or latex, but is thinner than the part 4 b.
  • a fourth part 4 d also forming a thin lip element, prolongs the third part 4 c so as to at least partly cover the outer surface of the semi-flexible lip 6 .
  • This part 4 d also provides a hygienic protection function. It can also be made of silicone or latex like the part 4 c. Fourth part 4 d may also be referred to as lip extension part 4 d.
  • the part 4 a 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 .
  • FIGS. 5 and 6 A second exemplary embodiment of the mask according to the invention is shown in FIGS. 5 and 6 .
  • 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:
  • the part 4 c 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 4 c is made of silicone, latex or a fibrous or woven material, for example.
  • the so-called structural part 4 b is more rigid than the part 4 c. 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 4 b′ 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 4 b′ can be made of silicone or latex, for example.
  • Part 4 b′ may also be referred to as lip securing part 4 b′.
  • This architecture takes into account the possible elastic distortions of the mask 2 , of the structural part 4 b and of the possible thread 13 , so that the assembly comprising the hygienic protection means 4 , the structural part 4 b and the possible elastic thread 13 , can easily be replaced after each use.
  • 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 .
  • 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.
  • FIG. 7 A third exemplary embodiment of the mask according to the invention is represented in FIG. 7 .
  • 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 .
  • 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:
  • 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.
  • a sealed, sterile and possibly transparent plastic bag also including disinfecting wipes.
