Abstract

In a sterilisation and disinfecting process employing steam, filter systems are employed which remove gas from the water. The filters are made from materials which are block, capillary or membrane filters of structured active carbon, ceramics, polysulphone, cellulose, or other materials having like physical, surface and electrostatic properties. A number of filters are assembled in parallel or series, to form a bank with comparable or similar effect. Further gas is removed from the water by warming and vacuum action. The resulting sterilised and decontaminated steam is used to sterilise and disinfect especially medical instruments and materials.

Description

Bei Reinigungsmaßnahmen zur Aufbereitung medizinischer Instrumente werden verschiedene flüssige bzw. gasförmige Desinfektions- und Waschlösungen zur Inaktivierung oder Abtötung sowie zur thermischen Denaturierung pathogener Keime eingesetzt. Ein wesentliches Problem dabei ist, daß nicht kondensierbare Gase die Dampfqualität der Sterilisation bzw. die desinfizierende Wirkung von Desinfektionslösungen in Desinfektioren beeinträchtigen. Dies gilt ebenso für Gassterilisatoren, deren Gas in flüssigem Zustand dem Sterilisator zugeführt wird sowie Geräten die in einer Geräteeinheit sowohl zur Gas- als auch der Dampfsterilisation dienen.When cleaning measures to reprocess medical instruments various liquid or gaseous disinfection and washing solutions Inactivation or killing and for the thermal denaturation of pathogenic germs used. A major problem is that non-condensable gases Steam quality of the sterilization or the disinfectant effect of Disinfectant solutions in disinfectants impair. This also applies to Gas sterilizers, the gas of which is supplied to the sterilizer in the liquid state and Devices in one device unit for both gas and steam sterilization to serve.

Zu diesen gasförmigen Bestandteilen (Inertgase) der Speisewasserversorgung sind insbesondere Stickstoff, Kohlendioxyd und Edelgase sowie verschiedene andere reaktionsträge, ungelöste Kohlenstoff- und Stickstoffverbindungen zu nennen.Among these gaseous components (inert gases) are the feed water supply especially nitrogen, carbon dioxide and noble gases as well as various others to mention inert, undissolved carbon and nitrogen compounds.

Zweifellos wird dieses Verfahren in vielen industriellen Bereichen bereits zur Entgasung genutzt. Bisher sind jedoch keine Sterilisatoren und Desinfektoren bekannt, die in der beschriebenen Anordnung nach Anspruch 1. ff über diese technisch kostengünstige Lösung in Verbindung mit der Keim- und Pyrogenfiltration im Bereich der Sterilisation, mangels der Kenntnisse über mögliche Beeinträchtigungen z. B. der Dampfsterilisation verfügen.Without a doubt, this process is already used for degassing in many industrial areas utilized. So far, however, no sterilizers and disinfectors are known in the described arrangement according to claim 1. ff about this technically inexpensive Solution in connection with germ and pyrogen filtration in the area of sterilization, lack of knowledge about possible impairments e.g. B. steam sterilization feature.

Bereits bekannt sind Verfahren, die über eine Erhitzung des Speisewasser von Dampfsterilisatoren in Tank- bzw. Mehrbettsystemen auf über 100°C gasförmige Anteile abtrennen.Methods are already known which involve heating the feed water Steam sterilizers in tank or multi-bed systems with gaseous components above 100 ° C split off.
