Definitions

  • Respiratory masks are in demand for widespread infection with viruses in the human respiratory tract and are currently (April 2020) not available in sufficient quantities.
  • such masks of the type FFP2 are particularly rare, but they are also only virus-resistant for a certain period of time and therefore have to be replaced frequently - e.g., as the moisture content increases
  • Task of the present invention therefore is to create a mask which permanently prevents contamination with viruses, in particular to shield the wearer from the Sars-CoV-2 type and, in the case of an infected wearer, also protects his environment from it.
  • the inventive step here is not to try to filter out viruses from the air we breathe, because with a virus diameter in the nanometer range, this can only be achieved with very fine filters and the correspondingly high resistance of the air we breathe.
  • the solution chosen was to irradiate a passageway in a chamber with UV radiation of about 220 to 254 nm, which should destroy the RNA of the viruses.
  • RNA virus In order to neutralize even enveloped RNA viruses, this should be done with a power of > 12mj/cm 2 . Since, due to various factors, the chamber does not have a uniform flow through all areas, this is done in a mirrored chamber.
  • the total power output of the UV light emitting diodes used should be at least 2.5 watt/cm 2 .
  • the associated UV radiation is produced conventionally with high-voltage vacuum discharge lamps, for which appropriate power sources and transformers are required.
  • Fig. 1 shows the mask (1), consisting of air-impermeable mask head (2), annular inside mirrored UV head (3), flexible air supply hose (4), mask edge (7) and retaining straps (9a, 9b).
  • the inside mirrored UV head (3) contains UV LEDs (8), a plug for power supply (6) and an on/off switch (10).
  • a supply line (5) to an external energy storage device (not shown) is connected to the power supply plug (6).
  • Fig. 2 shows the mask (1) in another version, consisting of an air-impermeable mask head (2), annular inside mirrored UV head (3), flexible air supply hose (4), mask edge (7) and retaining straps (9a, 9b).
  • the inside mirrored UV head (3) contains UV LEDs (8), plug for power supply (6) and an on/off switch (10).
  • a supply line (5) to an energy storage device (10) attached to a retaining strap (9a) is connected to the plug for the energy supply (6).
  • Fig. 3 shows the inside mirrored UV head (3) in detail, consisting of UV LEDs (8), plugs for the energy supply (6), on/off switch (10), one valve flap per lumen (11a, 11b) and the mirrored walls (13).

Abstract

Pour maintenir l'air inhalé exempt de virus, la zone de passage dans la zone d'admission d'un masque respiratoire est stérilisée par un rayonnement UV, de préférence avec des DEL de 220 à 280 nm de longueur d'onde.
