Abstract

There is described a method which is effective for the elimination and/or abolition of bacteria in compressed air lines in hospitals by connection of bactericidal and fungicidal chemisorption filters having a changing pH effect of less than 1 to higher than 13, so that the compressed air to be conveyed is supplied in a manner free from bacteria and viruses on the suction and/or pressure side of a compressed air generator by installation of filter elements having said property, so that the air can be used for the "supply of patients with breathing air in hospital rooms".

Description

Es ist bekannt, über Kompressoren komprimierte Luft über Lei­ tungssysteme in die Krankenhauszimmer zu den einzelnen Betten zur Versorgung von Beatmungsgeräten zur Verfügung zu halten. Diese Luft ist normale Außenluft, die mit Schadstoffen und Keimen belastet sein kann.It is known to compress compressed air via lei systems in the hospital rooms to the individual beds for the supply of respirators. This air is normal outdoor air that is polluted with and Germs can be contaminated.

Es ist weiterhin bekannt, daß Atemwegs- und Lungenerkran­ kungen durch die Beatmung über Druckluftleitungen und Beat­ mungsgeräte die Folge sind.It is also known that respiratory and lung cranes ventilation through compressed air lines and beat devices are the result.

Bakterien, die sich in den Leitungen ansammeln, sind vielfach die Ursache der Erkrankung.Bacteria that accumulate in the pipes are numerous the cause of the disease.

Um die Bildung von Bakterien in den Druckluftleitungen zu verhindern, wird erfindungsgemäß vorgeschlagen, ein bakteri­ zides und fungizides Chemisorptionsfiltersystem auf der Saug- und/oder Druckseite des Drucklufterzeugers, Kompres­ sors, Drehkolbengebläses, usw. vorzusehen.To prevent the formation of bacteria in the compressed air lines To prevent, a bacteri is proposed according to the invention zides and fungicidal chemisorption filter system on the Suction and / or pressure side of the compressed air generator, compresses sors, rotary lobe blower, etc.

Dieser bakterizide und fungizide Chemisorptionsfilter wird dadurch erfindungsgemäß gekennzeichnet, daß er Chemisorp­ tionsmassen aufweist, dieThis bactericidal and fungicidal chemisorption filter will characterized in that he chemisorp tion masses that

  • a) stark sauer unda) strongly acidic and
  • b) stark alkalisch wirksam sind.b) are strongly alkaline.

Vorzugsweise liegt der pH-Wert im sauren Bereich unterhalb pH-Wert 1 und oberhalb pH-Wert 13 im alkalischen Bereich.The pH in the acidic range is preferably below pH 1 and above pH 13 in the alkaline range.
