Respiratory protective mask for preventing droplet infection, aerosol and toxic dust

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...

AI Technical Summary

Problems solved by technology

[0002] The very large number of respirators of the type described on the market do not satisfy the required protection against droplet infection, since not only the breathing air 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 unfiltered and thus the lungs

[0003] Especially for glasses wearers, most of these masks are not suitable or at least not comfortable, because the exhaled air is also expelled in the area of ​​the nose and thus fogs up the glasses

[0004] Other masks that ensure a 100% seal are very laborious to wear or produce, and are therefore very expensive, so that these masks cannot be quickly and adequately used by people, for example in infected areas and in infectious diseases / pandemics
