- a user here a civil aircraft pilot, wears a respiratory protection mask 2, here a mask quick set up.
- 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, by. 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.
- a cord 7 is attached to the hygienic protection means 4 to facilitate extraction, 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 This portion 4b is for example also silicone or latex but is thinner than the part 4b.
- a fourth part 4d also forming a thin lip, extends the part 4c so as to cover at least partially the outer surface of the semi-flexible lip 6.
- This part 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 or to facilitate the gripping and / or extraction and replacement of the hygienic protection means 4.
