Definitions

  • the present invention relates to respiratory masks with hygienic protection.
  • the present invention relates to facial respiratory masks for physiological protection, in particular for aircrew personnel.
  • the invention relates, for example, respiratory protection masks used by civil aircraft pilots to fight against hypoxia in particular.
  • Protective masks for civil aircraft pilots are part of the aircraft and are used by several pilots successively, especially for tests or preventive uses of masks. It is understood that this causes some psychological discomfort for the pilots and that it is not without risk compared to certain contaminations.
  • An object of the invention is to at least partially overcome the aforementioned drawbacks.
  • the document EP 0 686 408 discloses a mask comprising an oronasal face cover adapted to be connected to a respiratory gas source and a semi-flexible lip having an edge adapted to position the oronasal face cover on a user's face.
  • the invention aims to provide a mask whose hygienic protection means are removable and can be easily replaced.
  • the document GB 2 76 404 discloses applying a substantially central portion of the hygienic protection means against the oronasal facing cover and applying a peripheral portion of the hygienic protection means against an inner rim of a layer of filter material extending opposite the oronasal face cover .
  • the hygienic protection means are thus applied axially between two elements (the mask and the rim) opposite.
  • the hygienic protection means are fixed with the mask, the layer of filter material and a sleeve enclosing a valve by means of a fixing ring.
  • the mask disclosed in this document is therefore complex, as well as the operation of replacing the hygienic protection means.
  • the first and second parts of the hygienic protection means comprise different materials.
  • the first part of the hygienic protection means covers an area of the semi-flexible lip which would have been, in the absence of hygienic protection means, in contact with the face once the mask in place thereon and the second part comprises a structural part which is housed in the internal groove of the semi-flexible lip.
  • a first exemplary embodiment of the mask according to the invention is represented on the figure 1 .
  • a user here a civil aircraft pilot, wears a respirator mask 2, here a quick set up mask.
  • This mask 2 comprises an oronasal face cover 10 and a semi-flexible lip 6.
  • a conduit 3 for conveying a breathing gas makes it possible to supply the mask 2 with respiratory gas from a source of respiratory gas 5.
  • This conduit 3 is fluidly connected to the oronasal face cover 10.
  • Removable hygienic protection means 4 here a filter, are placed by the driver inside the mask 2, for example when it takes place in the aircraft.
  • These hygienic protection means 4 are composed of at least two main parts 4a and 4b.
  • Part 4a filters the exhaled air and prevents any contamination from entering the inside of the mask and especially into a microphone or inspiratory 8 and / or exhalation valves 9.
  • Part 4a is for example made of a paper impregnated with an antibiotic, bactericidal or other substance.
  • the part 4b is made of a flexible and waterproof material, such as silicone or latex, for example, and ensures the maintenance of the hygienic protection means 4 in the mask 2, as well as the sealing of the hygienic protection means 4 with the mask 2 by contact between this part 4b and the inside of the semi-flexible lip 6. Possibly a cord 7 is fixed to the hygienic protection means 4 to facilitate the extraction of the mask 2.
  • a third part 4c forming a thin lip, extends the part 4b and protrudes from the semi-flexible lip 6 by a few millimeters in order to improve the wearing comfort of the mask 2 and the seal between the hygienic protection means 4 and the face of the user 1.
  • This part 4c is for example also silicone or latex but is thinner than part 4b.
  • a fourth portion 4d also forming a thin lip, extends the portion 4c so as to at least partially cover the outer surface of the semi-flexible lip 6.
  • This portion 4d also provides a hygienic protection function. It can also be silicone or latex, as part 4c.
  • the part 4a has a corrugated shape, with waves substantially centered inside the mask 2 and / or the inspiratory valve 8, in order to reduce the pressure drops and / or to facilitate gripping and / or extraction and replacement of the hygienic protection means 4.
  • a second exemplary embodiment of the mask according to the invention is represented on the Figures 5 and 6 .
  • the mask 2 according to the invention comprises an oronasal face cover, a semi-flexible lip and fluidic connection means similar to those of the embodiment described above.
  • the figure 5 is more particularly the semi-flexible lip 6 whose edge 11, intended to be in contact with the face of a user, is covered with hygienic protection means 4. This edge comes back to the center and the inside of the mask 2, forming an internal groove 12.
  • the part 4c which isolates the semi-flexible lip 6 of the skin P of the user 1 is placed all around this semi-flexible lip 6. It is placed on the outer part of the semi-flexible lip 6, but possibly also over a large part of its internal part.
  • This part 4c is made of silicone, latex or a fibrous or woven material, for example.
  • Part 4b called structural is more rigid than part 4c. It is for example silicone or latex. She has a suitable shape to fit into the internal groove 12 of the semi-flexible lip 6. It allows a stable positioning of the hygienic protection means 4, preventing them from leaving the mask 2 during use thereof.
  • the last part 4b ' that possibly comprising an elastic thread 13 is fixed on the entire outer periphery of the hygienic protection means 4 in order to maintain them positioned in a stable manner by preventing them from entering the mask 2 during its use.
  • This part 4b ' can be silicone or latex, for example.
  • This architecture takes into account the possible elastic deformations of the mask 2, the structural part 4b and the possible wire 13, so that the assembly consisting of the hygienic protection means 4, the structural part 4b and the possible wire elastic 13 can be easily replaced after each use.
  • a flexible structure is placed between the hygienic protection means 4 and an inner part of the semi-flexible lip 6.
  • This flexible structure such as a thin film made of silicone or latex, for example, protrudes from the lip 6.
  • another flexible structure such as a thin film, can be placed outside the hygienic protection means 4, inside the semi lip. -souple 6 and protruding from it.
  • a third exemplary embodiment of the mask according to the invention is represented on the figure 7 .
  • this third embodiment of the mask 2 according to the invention comprises an oronasal face cover, a semi-flexible lip and fluidic connection means similar to those described above.
  • the figure 7 is more particularly the semi-flexible lip 6 whose edge 11, intended to be in contact with the face of a user, is provided with hygienic protection means 4. This edge 11 returns towards the center and inside of the mask 2, forming an internal groove 12.
  • the hygienic protection means 4 are essentially placed outside the semi-flexible lip 6.
  • the hygienic protection means 4 consist essentially of a thin film which surrounds the semi-flexible lip 6 on the outside. .
  • the clean elasticity of this thin film makes it easy to place it around the periphery of the semi-flexible lip 6.
  • This thin film is for example silicone or latex.
  • This thin film thus makes it possible to ensure a much better seal than the masks of the prior art.
  • the hygienic protection means described above are particularly economical which makes their regular use and replacement inexpensive.
  • the hygienic protection means can be stored in a waterproof, sterile and possibly transparent plastic bag, also comprising disinfecting wipes.
  • a waterproof, sterile and possibly transparent plastic bag also comprising disinfecting wipes.
