Definitions

  • the invention relates to a respiratory protection mask.
  • the invention applies in particular, but not exclusively, to respiratory protection masks capable of filtering solid or liquid particles suspended in the air, and intended for a single use.
  • Respiratory protection masks are used in particular by medical personnel to avoid not only the contamination of a patient by the projection of aerosols emitted by medical personnel, but also to avoid contamination of medical personnel by inhalation of biological agents present in the air, such as viruses.
  • molded masks have the disadvantage of being bulky and take up storage space, unlike foldable masks such as those described in G-A-1556679.
  • the document EP-A2-118278 discloses a foldable mask comprising an upper part, a lower part and a connecting part connecting the upper part and the lower part.
  • Two cords allow to have the mask on the head of the user.
  • the two cords are fixed inside the mask between the upper and lower parts or between one of the upper or lower parts and a reinforcing element also arranged inside the mask.
  • WO 01/89330 also discloses a foldable mask whose ends of cords used to secure the mask on the wearer's face are fixed under a filter band placed along the periphery of the mask. This band, straddling the peripheral edge of the mask, is sewn or welded to the mask to improve breathability.
  • the respiratory protection mask ensures a good seal on the face to avoid contamination of the wearer.
  • the mask is easy to put on and remove and provides a better feeling of comfort.
  • the invention provides a respiratory protection mask comprising a porous filter protection piece and a fastening element secured to said piece so as to maintain said piece in front of at least the nose and the mouth of a carrier, the porous part being provided with discrete outer zones on which the fastening element is secured, said mask further comprising a protective strip which is provided along at least a portion of an edge of the protective member, the strip being secured to the protective member on the fastening zones of the fastening element, said fastening element being, on these zones, interposed between the protective piece and the protective strip so that the band covers the fastening element.
  • the figure 1 schematically represents a perspective view of a respiratory protection mask with protective strips according to a first and a second embodiment of the invention.
  • the figure 2 schematically represents a perspective view of a respiratory protection mask with a protective strip according to the second embodiment.
  • FIG. figure 3 schematically represents the upper and lower unassembled elements of a protective mask shown in FIG. figure 2 .

  • the figure 5 schematically represents a view from above of the protective mask shown in FIG. figure 2 .
  • the figure 6 schematically represents a view from below of the protective mask shown in FIG. figure 2 .
  • FIGS. 7 to 9 schematically represent a sectional view along the axis AA of a respiratory protection mask according to different embodiments of the protective strip.
  • lower edge and upper edge in relation to the elements define, respectively the nearest edge and the farthest edge of the face, when the mask is worn.
  • the invention proposes a respiratory protection mask, in particular for single use.
  • the mask is designed to retain solid or liquid particles suspended in the air and in particular viruses or bacteria likely to cause diseases such as influenza.
  • the respiratory protection mask 1 comprises a porous protection piece 2 by filtration and a fastening element 3 secured to said piece so as to maintain said piece in front of at least the nose and the mouth of a wearer.
  • the protective part is formed in particular of two elements 4,5, respectively upper and lower, which are associated with each other so as to be applied respectively facing the nose and the chin of the wearer.
  • the figure 3 illustrates the upper elements 4 and lower 5 and the attachment element 3 before being secured.
  • the combination of elements is made for example by welding such as ultrasonic welding, high frequency laser or heat, sewing, gluing or folding.
  • the lower and upper elements are of trapezoidal shape, three sides of each trapezium being associated two by two to form the protective part, the large base of each trapezium being free to form the upper and lower edges of said room.
  • Such a mask is called foldable type, that is to say that when it is not worn, the mask is substantially flat and is easily stackable.
  • the two trapezoidal elements form a section whose periphery comes into contact with the wearer's face.
  • the elements have the same dimensions so as to be perfectly superimposable.
  • the elements are of different size and / or shape (s).
  • the height of the trapezoidal lower member is greater than the height of the trapezoidal top member, so that the mask covers a larger portion of the chin.
  • the protective piece is formed of three elements associated with each other, two elements being foldable on a central element.
  • Such a type of mask is described in EP-A-814871 .
  • the porous part 2 is provided with discrete outer zones 6, 7 on which the fastening element 3 is secured.
  • the discrete outer zones 6, 7 are placed at the lateral ends of the lower edge 9 of the protective part 2.
