FIELD: medicine. ^ SUBSTANCE: present invention refers to respirators and is designed for preventing the penetration of contaminants and particles in user's airways. A horizontally flat-fold filter face respiratory mask 10 contains a system of fastening belts 14 and a base 12 of the mask having a front surface, a first segment of a perimetre 24a and a longitudinal axis 34. A nasal clamp 30 is attached to the base 12 of the mask in the middle and next to the first segment of the perimeter 24a of the base 12 of the mask. Near the nasal clamp 30 there is an inducing component 32 visible on the front surface of the base 12 of the mask and specifying the place of the longitudinal symmetry axis of the nasal clamp. ^ EFFECT: use of such inducing component visible on the front surface of the base of the mask enables the user to determine quickly in which place the nasal clamp is to be folded when preparing the mask for putting on. ^ 12 cl, 5 dwg |
