Abstract

A biomonitor instrument checks the efficacy of a disinfecting process on drinking water. The biomonitor is a silicon hose bearing a biofilm aged up to four years old. The biofilm is generated exclusively by exposure to a constant flow of drinking water, thus simulating the worst-case conditions existing within a water pipe. If the microorganisms existing on the silicon hose are de-activated, the inference may be drawn that the disinfecting process was successful. Back-flow prevention valves prevent recontamination of the biomonitor, whose inlet is protected by a pressure-reduction assembly. The silicon hose biomonitor is introduced in sterile condition.

Description

Beschreibung der Erfindungdescription the invention

Mit dieser Erfindung wird ein Instrument zur Kontrolle des Biofilmbildungspotentials in wasserführenden Leitungssystemen für den praktischen Einsatz vor Ort, u.a. in sensiblen Hygienebereichen oder als Erfolgskontrolle nach der Durchführung einer Desinfektionsmaßnahme bereitgestellt. Da Biofilme mit der Zeit in fast allen trinkwasserführenden Systemen entstehen und durch die Abgabe von fakultativ pathogenen Mikroorganismen und deren Stoffwechselprodukte (u.a. Toxine) vor allem im Health Care Sektor ein erhebliches gesundheitliches Risiko darstellen können, ist eine rechtzeitige Einschätzung des Gefährdungspotentials sehr wichtig. Eine Kontrolle des Biofilmbildungspotentials in trinkwasserführenden Systemen und somit der Quelle von pathogenen Mikroorganismen und die Kontrolle des Erfolgs einer Desinfektionsmaßnahme gegen Biofilme sind mit den etablierten Methoden nur schwer möglich. Durch die kompakte Bauweise und die verwendeten Bauteile (u.a. Ventile, die eine mögliche Rückverkeimung durch den verwendeten Bioindikator verhindern) konnte ein System erschaffen werden, das vor Ort einfach an bestehende Wassersysteme angeschlossen werden kann und so eine Überwachung des Trinkwassers ermöglicht. Das System oder Teile davon können zudem leicht ausgetauscht und zur Untersuchung ins Labor geschickt werden. Bisherige Kontrollen beinhalteten nur eine Wasserprobe, unser System simuliert zusätzlich den Zustand des Rohrleitungssystems, in dem das Wasser fließt. Durch den Austausch des Bioindikators im Inneren des Geräts kann sehr einfach zwischen den verschiedenen Einsatzbereichen gewechselt werden.With This invention will become an instrument for controlling biofilm formation potential in water-bearing Management systems for the practical use on site, u.a. in sensitive hygiene areas or provided as a success check after the execution of a disinfection measure. Because biofilms over time in almost all drinking water Systems arise and through the delivery of facultative pathogenic Microorganisms and their metabolites (including toxins) especially in the health care sector, a significant health risk can represent is a timely assessment of the risk potential very important. A control of biofilm formation potential in potable water Systems and thus the source of pathogenic microorganisms and The control of the success of a disinfection measure against biofilms are with the established methods are difficult. Due to the compact design and the components used (including valves that have a potential recontamination prevent by the used bioindicator) could a system be created on site simply to existing water systems can be connected and so a monitoring of drinking water allows. The system or parts of it can also easily exchanged and sent to the laboratory for examination become. Previous controls included only one water sample, our system simulates additionally the condition of the piping system in which the water flows. By the replacement of the bio-indicator inside the device can very easily switched between the different areas of application become.

Einsatzbereicheareas of application

(1) As success check of a disinfection measure.
(2) As a monitor in all areas where hygienic Drinking water or sterile water is needed.

Claims

Device (biomonitor) for controlling the success of a disinfection measure in drinking water-carrying piping systems. The device for this application is characterized in that the bio-indicator used is a silicone tube overgrown with up to 4 years of biofilm. This biofilm was generated exclusively by constant drinking water flow and thus simulates pipelines in a water-bearing system under "worst case" conditions. If the existing microorganisms in the bioindicator are inactivated by a disinfection measure, it can be assumed that the disinfection was successful. In addition, the construction method allows on-site use and is not dependent on a laboratory. Check valves prevent recontamination by the bioindicator, and a pressure reducer reduces high inlet pressures.

device (Biomonitor) to control the biofilm formation or microbial potential a drinking water leading Line system. The device For this Scope is characterized by the use of a at the beginning of the trial sterile silicone tube, in which, depending on the degree of contamination of the aquifer to be checked Systems, a biofilm can grow. By choosing the tubing have existing microorganisms ideal growth conditions. The Speed of biofilm development and the shape of the biofilm gives direct information about this the degree of contamination or over the sterility of the examined system. With the exception of depending on the application chosen Bioindicators, both devices consist of the same autoclavable Materials and are by check valves against recirculation and Dehydration assured. By a pressure reducer high input pressures be reduced. Through a quick coupling the equipment simply connected to existing water supply points or in the water-bearing system integrated.
