Definitions

  • the invention is based on a respiratory protection mask for the respiratory protection of a mask wearer, with a mask body and at least one filter for filtering a fluid, preferably air, flowing through the mask and / or the mask body.
  • Filtering half masks are mask and filter in one.
  • the filter can usually not be replaced. Rather, these half masks are completely disposed of after use or when the filter is exhausted.
  • Half masks are usually relatively light and comfortable to wear, have a relatively large filter surface and are relatively hygienic.
  • the disadvantage is that conventional half masks are generally more expensive to use than full masks and are usually not suitable for filtering gaseous pollutants.
  • Half masks are often used as occupational safety, e.g. in the medical field to protect against infections, but also e.g. when working with dust, wood, fiberglass or concrete, have a mask body, usually made of rubber or silicone, and encompass the mouth and nose of a mask wearer .
  • a mask body usually made of rubber or silicone, and encompass the mouth and nose of a mask wearer .
  • one or two filter cartridges can be attached to the mask body.
  • a half mask of the type mentioned is known from DE 40 17336 C1.
  • the known half mask has a half mask body with a sealing edge which is inserted into a filter holder.
  • a filter is attached to the filter holder in the mouth area.
  • the filter holder extends from the mouth area to the cheek area of the half-mask body and rests freely on the half-mask body. Inhalation takes place through an inhalation valve, and exhalation runs through an exhalation valve, which is buttoned into the half-mask body in the chin area is.
  • a strap with which the half mask can be attached to the head of an equipment wearer is fastened in an eyelet of the filter holder.
  • the tightness between the oral cavity and the environment is determined by the geometry and rigidity of the sealing edge, the flexibility of the half mask body and the lateral support of the half mask body by the filter holder.
  • a soft mask body or soft sealing edge increases the wearing comfort, but worsens the mechanical stability, while a high rigidity of the mask body or the sealing edge is perceived as uncomfortable when the half mask is worn.
  • the filter holder resting on the half mask body in the cheek area only brings about a certain lateral stabilization of the half mask body, while there is no direct interaction between the filter holder and the sealing edge, which is decisive for the tightness of the half mask.
  • a half mask known from GB-PS 761 263 consists of a flexible half mask body in which a filter holder with a filter is inserted in the mouth area.
  • a wire helix is vulcanized into the mask body in order to give the sealing edge a corresponding rigidity.
  • the wire helix can be roughly adapted to the face contour of the mask wearer.
  • the half mask is given increased rigidity in the area of the sealing edge due to the wire helix, the half mask can only be worn by a specific mask wearer because of the individually curved wire helix. This makes handling more difficult in practical use, since after the device has been reprocessed, the individual preformed half masks have to be returned individually to the mask wearer.
  • the invention is based on the object of improving a half mask in such a way that, in addition to being comfortable to wear, it also has a high degree of tightness for different face shapes and has particularly good filtering of a fluid flow flowing through the mask.
  • the mask body has a cutout and / or b) the mask body has at least one support means which, when the mask is in place, is arranged at least in the cheek area and / or in the nose area of a mask wearer; and / or c) the at least one filter at least one or more from heating coil, biofilter and / or moss, moisture storage, airgel, gel foam, activated carbon, salt water filter, labyrinth filter and / or labyrinth, UV filter and / or UV radiator, electrical and / or an electrostatic filter, membrane filter and / or particle filter.

  • the mask can thus be adapted to the face shape of a mask wearer be adjusted.
  • the mask can be adapted to the face shape of a mask wearer.
  • the proppant can increase the mechanical stability of the mask.
  • the support means can have a former with which the mask can be brought into a shape adapted to the face shape of a mask wearer.
  • the filter can be suitably selected.
  • the mask can be a half mask.
  • the mask body can be a half-mask body.
  • the mask according to the invention can be suitable for filtering or killing germs, bacteria and / or viruses, for example corona viruses or influenza viruses, from the air to be inhaled by the mask wearer. In this way, the mask can protect the mask wearer from infections or respiratory diseases, for example.
  • the mask can have at least one suitable filter, e.g. as described below. It can also be provided that the mask alternatively or additionally contains particles, e.g. fine dust (e.g.
