Embodiment Construction

[0023] figure 1 A basic mask body 1 is shown, which covers parts of the face in the area of ​​the mouth and nose and is held in an optimal position by a number of straps 6, 7, preferably made of elastic material; 6 , 7 are fastened to the basic mask body 1 by means of the strap fastening 5 in such a way that the straps can be replaced without problems if necessary after a certain service life. The basic mask body 1 consists of a material that is still slightly flexible and can be deformed manually so that it can be adapted to any face shape, but at the same time is sufficiently rigid to hold the existing shape for a long time. Ideal shape once (if no external forces act on it afterwards).

[0024] The circular surrounding material surface with the intermediate web 2 serves to connect the filter material 8 in a gas-tight manner to the surface of the circular surrounding material surface and sufficiently separates the filter material 8 from the mouth by the existing intermediat...

Abstract

The invention relates to a respiratory protective mask, and the mask consists of a base mask body, which is held in position by means of an elastic fastening strap and in which a filter material of a preferably FFP3 quality grade is fitted on a circumferential surface in an air-tight manner; the mask has a circumferential sealing portion which encloses the outer edge of the base mask body and thus ensures a 100% seal of the base mask body with respect to the face skin surface, in particular in the area of the nose and at the chin.

Description

technical field [0001] The invention relates to a respiratory protective mask, in particular for preventing droplet infection, which covers the mouth and especially the nose region in such a way that it ensures that, through a corresponding seal between the facial skin and the basic mask body, the air to be inhaled The air only passes through the filter material into the nose and mouth and into the lungs if 100% of the instructions for use are followed when wearing the respiratory protection mask. Background technique [0002] The very large number of respirators of the type described on the market do not satisfy the required protection against droplet infection, since the breathing air not only reaches the lungs through the filter material / respirator filter, but also the external air in particular in the nose. The possibility arises in the region that it may reach the nose and mouth, and thus the lungs, unfiltered. [0003] Especially for glasses wearers, most of these mas...
