Abstract
Filteratemschutzgerät bestehend aus einem Maskenkörper (1), einem Flanschstück (2) und einem Filterelement (3), wobei das Flanschstück (2) zwischen Maskenkörper (1) und Filterelement (3) positioniert ist, dadurch gekennzeichnet, dass das Filterelement (3) parallel zur Strömungsrichtung (7) der Atemluft ausgerichtete röhrenartige zylindrische Öffnungen (4) umfasst, in die zylindrische zigarettenfilterartige Filterstücke (5) eingeführt sind. Filter respirator consisting of a mask body (1), a flange piece (2) and a filter element (3), the flange piece (2) being positioned between the mask body (1) and filter element (3), characterized in that the filter element (3) is parallel Includes tubular cylindrical openings (4) oriented towards the direction of flow (7) of the breathing air, into which cylindrical cigarette filter-like filter pieces (5) are inserted.
Description
Filteratemschutzgeräte sind im Bereich der Gesundheitsvorsorge weit verbreitet. Sie dienen zur Reinigung der Atemluft von Partikeln, Gasen, Dämpfen oder Aerosolen.Filter respirators are widely used in the field of health care. They are used to clean the air we breathe from particles, gases, vapors or aerosols.
Im Wesentlichen gibt es zwei Gruppen von Filteratemschutzgeräten. Bei der einen Gruppe bildet das Filterelement einen integralen Bestandteil des Maskenkörpers. Das heißt, der Maskenkörper besteht aus einem Filtergewebe. Bei der anderen Gruppe ist das Filterelement außerhalb des Maskenkörpers angeordnet, aber gasdicht mit dem Maskenkörper über ein Flanschelement verbunden.There are essentially two groups of filter respirators. In one group, the filter element forms an integral part of the mask body. This means that the mask body consists of a filter fabric. In the other group, the filter element is arranged outside the mask body, but is connected gas-tight to the mask body via a flange element.
Die vorliegende Erfindung gehört zu der Gruppe von Filteratemschutzgeräten, bei der Maskenkörper und Filterelement über ein Flanschstück verbunden sind.The present invention belongs to the group of filter respirators in which the mask body and filter element are connected via a flange piece.
Bei beiden Gruppen von Filteratemschutzgeräten kann das Filterelement nach Gebrauch nicht gereinigt oder wiederaufbereitet werden. Es muss ein Neuteil beschafft werden.In both groups of filter respirators, the filter element cannot be cleaned or reprocessed after use. A new part has to be procured.
Die vorliegende Erfindung hat sich die Aufgabe gestellt, den oben genannten Nachteil von Filteratemschutzgeräten zu beseitigen und Filteratemschutzgeräte bereitzustellen, bei denen das Filterelement wiederaufbereitet werden kann.The object of the present invention is to eliminate the above-mentioned disadvantage of filter respirators and to provide filter respirators in which the filter element can be reprocessed.
Die Lösung der Aufgabe wird durch den Austausch von zylindrischen zigarettenfilterartigen Filterstücken nach Gerbrauch erzielt. Diese zylindrischen zigarettenfilterartigen Filterstücke filtern die Atemluft und sind in röhrenartigen zylindrischen Öffnungen des Filterelements mit ihrer Längsachse parallel zur Strömungsrichtung der Atemluft positioniert.The problem is solved by exchanging cylindrical cigarette filter-like filter pieces according to usage. These cylindrical cigarette filter-like filter pieces filter the breathing air and are positioned in tubular cylindrical openings of the filter element with their longitudinal axis parallel to the direction of flow of the breathing air.
