Description
Beschre iDescribe i
Die Forderung nach keimfreiem Wasser (wie auch nach staubfreier Luft) spielt heute in weiten Bereichen der industriellen Fertigung, besonders aber auch in der Medizin eine zunehmend größere Rolle.The demand for germ-free water (as well as dust-free air) is playing an increasingly important role in many areas of industrial production, but especially in medicine.
Besonders aktuell ist die Problematik der Wasserentkeimung im Bereich der Zahnbehandlung und der Kieferchirurgie. Um einer möglichen Keimübertragung durch Kühl- und Mundspülwasser vorzubeugen, ist die Entkeimung des verwendeten Leitungswassers dringend erforderlich.The problem of water disinfection is particularly relevant in the field of dental treatment and jaw surgery. In order to prevent possible transmission of germs through cooling and mouthwash water, it is urgently necessary to disinfect the tap water used.
Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, ein besonders für den zahnärztlichen Bereich hochwirksames, kompaktes und einfach zu installierendes Gerät bereitzustellen, welches es gewährleistet, eine Kontaminierung des Patienten mit keimhaltigem Wasser auszuschließen.The invention specified in the protection claim is based on the problem of providing a highly effective, compact and easy-to-install device, particularly for the dental field, which ensures that contamination of the patient with germ-containing water is excluded.
Dieses Problem wird durch die kombinierte Wirkung der Keimtötung durch UV-Strahlung und der Desinfizierung durch Zudosierung von Wasserstoffperoxid durch die im Schutzanspruch genannte Erfindung gelöst.This problem is solved by the combined effect of germ killing by UV radiation and disinfection by dosing hydrogen peroxide by the invention mentioned in the protection claim.
Die gesamte Vorrichtung kann in kompakter Form an einer Trinkwasserzuleitung mittels eines Bypasses installiert werden.The entire device can be installed in a compact form on a drinking water supply line using a bypass.
Der mit der Erfindung erzielte Vorteil besteht hauptsächlich darin, daß erstmalig für den zahnmedizinischen Bereich ein Gerät zur Verfügung steht, das in der Lage ist, das zur Behandlung verwendete Wasser (Kühl- und Mundspülwasser in zahnärztlichen Geräten wie: Wasserspritze, Wehrfunktionsspritze, Winkelstück, Turbine, Trinkwasserspender, Zahnsteininstrumenten) zu entkeimen und somit das mit einer Kontaminierung verbundene Risiko für die Patienten zu minimalisieren.The main advantage achieved with the invention is that for the first time a device is available for the dental field that is able to disinfect the water used for treatment (cooling and mouthwash water in dental devices such as: water syringes, military syringes, contra-angles, turbines, drinking water dispensers, tartar instruments) and thus minimize the risk for patients associated with contamination.

Ein mögliches Ausführungbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.A possible embodiment of the invention is shown in the drawing and is described in more detail below.
Das zu behandelnde Wasser gelangt über den Rohwassereinlauf (3) zunächst über einen Kontaktwasserzähler (5) in einen physikalischen Vorfilter (7) zur Entfernung eventuell vorhandener physikalischer Verunreinigungen.The water to be treated enters the raw water inlet (3) first via a contact water meter (5) into a physical pre-filter (7) to remove any physical impurities that may be present.
Der Filter besteht aus einem Kunststoffgehäuse (6) mit einem darin befindlichen Standardfilterelement. Als Filtermaterial wird Polypropylen verwendet, welches Verschmutzungen innerhalb der Filtermatrix zurückhält.The filter consists of a plastic housing (6) with a standard filter element inside. The filter material used is polypropylene, which retains dirt within the filter matrix.
Nach dem Vorfilter passiert das Wasser einen Aktivkohlefilter
(8). Mit dem ebenfalls in einem Kunststoffgehäuse (6)
untergebrachten Filtersubstrat können auch feinste Feststoffpartikel
abgeschieden werden. Außerdem adsorbiert die Aktivkohle organische Moleküle, wie z.B. Pestizidrückstände.
Beide Filtergehäuse sind mit Entlüftungsventilen als Überdruckschutz ausgestattet.After the pre-filter, the water passes through an activated carbon filter (8). The filter substrate, which is also housed in a plastic housing (6), can separate even the finest solid particles. The activated carbon also adsorbs organic molecules, such as pesticide residues.
Both filter housings are equipped with vent valves to protect against overpressure.
Vor dem Eintritt in die UV-Einheit (12) wird dem Wasser eine dem Gesamtdurchfluß angepaßte Menge Wasserstoffperoxid zudosiert. Die Konzentration des Wasserstoffperoxids entspricht den gesetzlichen Vorschriften, ohne den Wirkungsgrad hinsichtlich der Keimabtötung zu beeinträchtigen.Before entering the UV unit (12), a quantity of hydrogen peroxide is added to the water that is adapted to the total flow. The concentration of the hydrogen peroxide complies with the legal regulations without affecting the effectiveness in killing germs.
Das Wasserstoffperoxid befindet sich in einem chemikalienbeständigen Vorratsbehälter (11). Mittels der Dosierpumpe (10) wird die ensprechende Menge Wasserstoffperoxid in den Wasserstrom eingespeist.The hydrogen peroxide is located in a chemical-resistant storage container (11). The appropriate amount of hydrogen peroxide is fed into the water flow using the dosing pump (10).
Die Dosierpumpe ist mit dem Kontaktwasserzähler (5) gekoppelt. Entsprechend der von diesem registrierten registrierten Durchflußmenge dosiert die Pumpe die festgelegte Menge Wasserstoffperoxid zu.The dosing pump is coupled to the contact water meter (5). The pump doses the specified amount of hydrogen peroxide according to the flow rate registered by the meter.
Auf diese Weise wird die im Reinwasser enthaltene Konzentration an Wasserstoffperoxid ständig konstant gehalten.In this way, the concentration of hydrogen peroxide in the pure water is kept constant.
Im letzten Schritt gelangt das Wasser in die UV-Einheit, wo aufgrund des Prinzips der Entkeimung durch UV-Strahlung alle Bakterien, Keime und Viren abgetötet werden.In the final step, the water enters the UV unit, where all bacteria, germs and viruses are killed based on the principle of disinfection by UV radiation.
Die UV-Einheit besteht aus einem zylindrischen Behälter (13) mit je einem Anschluß für den Wasserzulauf und -ablauf. Im Behälter befindet sich ein UV-Quecksilberniederdruckstrahler (17), der von einem aus Quarzglas bestehenden Mantel umgeben ist. Während seines Weges vom Zulauf zum Ablauf wird das Wasser der von der UV-Lampe emittierten Strahlung ausgesetzt und auf diese Weise keimfrei gemacht.The UV unit consists of a cylindrical container (13) with a connection for the water inlet and outlet. The container contains a low-pressure UV mercury lamp (17) which is surrounded by a jacket made of quartz glass. During its journey from the inlet to the outlet, the water is exposed to the radiation emitted by the UV lamp and thus made germ-free.
Nach dem Durchströmen des Kontaktwasserzählers (5) kann das mit Wasserstoffperoxid angereicherte und keinfreie Wasser über den Reinwasserauslauf (4) das Gerät verlassen und der Behandlungseinheit des Zahnarztes zugeführt, oder anderweitig genutzt werden.After flowing through the contact water meter (5), the water enriched with hydrogen peroxide and free of nitrates can leave the device via the pure water outlet (4) and be fed to the dentist's treatment unit or used for other purposes.
