摘要

respiratory masks for air particles, in particular micro-organisms,marked by it,that a respiratory mask is applied to the face (1) in a consistent manner,that an air outlet includes a flat valve housing (2), with an internal moving disc (3), which closes the air outlet when inhaling, when exhaling, and preferably is integrated into the respiratory protection mask (1) below,that a stretchable connecting element (4) causes the respiratory mask to be applied uniformly around the nose and chin area of the living being and that this stretchable connecting element (4) is attached to the head and neck area,a filter housing connector (5) is tightly integrated into the respiratory mask housing (1) and incorporates a filter element housing (6),that the filter element housing (6) consists of at least two main parts, the filter element housing component at the bottom (7) and the filter element housing component at the top (9) and at least one filter housing sealing elements (11),that the filter element housing component at the bottom (7) includes an inner airframe at the bottom (8) which is designed with a height of at least 15mm to 120 mm, and that component is individually removable from the overall system,that the filter element housing component at the top (9) includes an inner air duct wall at the top (10), which is designed with a height of at least 15mm to 120 mm, and firmly integrated into the filter housing connection element (5), in a consistent form,that after the assembly of the filter element housing part below (7) into the filter element housing part above (9) a filter element housing is formed (6),that it provides an intake air (12), at least three related airflow chambers (13), and an outlet filter air (14) for the respiratory mask; andthat, because the 3-stream chambers have to be flown in their longitudinal direction, the total mean length of all air flow channels together from at least 45 mm to 360 mm, which has to pass through the breath air, andthat, depending on the design, a significantly longer period of time is available for more effective cleaning of the respiratory air of particles and also for attaching micro-organisms to the inner walls of the airflow chambers (13) for the micro-organisms; andthat the filter element housing component below (7) can be removed and cleaned.
