Description

Die Erfindung bezieht sich auf die Reduzierung der Ver­ keimung und Infektionsgefahr bei Dentalgeräten.The invention relates to the reduction of Ver Germination and risk of infection in dental devices.

Im Wasserkreislauf bis zum Dentalbohrer können Keime aus einem vorgeschalteten Ionenaustauscher oder aus dem Lei­ tungssystem zum Befall oder zur Verstopfung der Zuleitung (zum Beispiel Pilze, Algen) führen. Durch Wasserrück­ schlag vom Bohrer gelangen Bakterien und pathogene Keime, zum Beispiel Hepatitis-Viren, in den angrenzenden Zulei­ tungsbereich. Über Sprühnebel verbreiten sich diese Kei­ me in der Umgebung auf zum Beispiel Arzt, Geräte. Die Keime finden sich auch im Wasserablauf wieder.Germs can spread from the water circuit to the dental drill an upstream ion exchanger or from the Lei system for infestation or blockage of the supply line (for example mushrooms, algae). By water return bacteria and pathogenic germs for example hepatitis viruses, in the adjacent Zulei area. These ki spread through spray mist me in the area on for example doctor, equipment. The Germs can also be found in the water drain.

In der DE-OS 34 35 553 sind für Gasleitungssysteme in Beatmungsgeräten geeignete Maßnahmen gegen Bakterien­ wachstum vorgeschlagen. Sie sind jedoch auf den Wasser­ kreislauf nicht ohne weiteres übertragbar.In DE-OS 34 35 553 are for gas pipe systems in Respirators suitable measures against bacteria growth suggested. However, they are on the water circuit not readily transferable.

Die zur Wasserentkeimung üblicherweise angewandten Ver­ fahren, wie zum Beispiel Chlorung oder Silberung, erge­ ben keine sichere Wirkung, weil das Chlor an den orga­ nischen Schlauchwänden verbraucht wird bzw. die Silber­ ionen erst nach Stunden wirken.The Ver usually used for water disinfection driving, such as chlorination or silvering ben no safe effect because the chlorine on the org African hose walls is consumed or the silver ions take effect only after hours.

Im Zuleitungsbereich zu den Dentalgeräten steht das Was­ ser längere Zeit und schlägt vom Bohrer zurück. In Ris­ sen oder an Stellen ungünstiger Konstruktion sind gute Bedingungen für Keimwachstum gegeben. Mikrobizide Wirk­ stoffe herkömmlicher Art, die man zum Beispiel den Schläuchen zumischt, haben eine nicht ausreichende keim­ tötende Wirkung.What is in the supply area to the dental equipment longer and strikes back from the drill. In Ris or in places of poor construction are good Conditions for germ growth are given. Microbicidal active fabrics of a conventional type that are used, for example, in Hoses mixed in, have an insufficient germ  killing effect.

Eine elektrochemische Entkeimung ist in der DE-OS 34 30 616 beschrieben. Zum Entkeimen von Trinkwasser wird ein Verfahren vorgeschlagen, nach dem das zu be­ handelnde Wasser durch eine nach dem Prinzip der elek­ trolytischen Dissoziation arbeitende Zelle mit zwei an Gleichspannung anliegenden Elektroden hindurchgeleitet wird. Die elektrolytische Zelle besteht zum Beispiel aus einem Kunststoffgehäuse, in dem zwei plattenförmige Elektroden in einem Abstand von etwa 0,5 bis 2 mm zuein­ ander angeordnet sind. Der dazwischenliegende Raum bil­ det eine Durchflußkammer, die einerseits mit einem Zu­ flußkanal und andererseits mit einem Abflußkanal in Ver­ bindung steht. Zwischen Zufluß- und Durchflußkammer be­ findet sich ein Verteilerraum, der zwei ebenfalls in Ab­ stand zueinander angeordnete Meßelektroden aufnimmt.Electrochemical disinfection is in DE-OS 34 30 616. For sterilizing drinking water a method is proposed according to which to be acting water through an elec trolytic dissociation working with two cells DC voltage applied electrodes passed through becomes. The electrolytic cell consists of, for example a plastic housing in which two plate-shaped Electrodes at a distance of about 0.5 to 2 mm are arranged differently. The space in between bil det a flow chamber, on the one hand with a closed flow channel and on the other hand with a drain channel in Ver bond stands. Between the inflow and flow chamber there is a distribution room, the two also in Ab stood to each other arranged measuring electrodes.

Das Kunststoffgehäuse ist längsgeteilt. Zwischen den beiden Hälften ist im montierten Zustand eine Dichtung vorgesehen. Die Platten der Elektroden bestehen vorzugs­ weise aus Platin oder platiniertem Titan. Um eine besse­ re Durchwirbelung des vom Zufluß über den Verteilerraum und die Durchgangskammer zum Abflußkanal fließenden Was­ sers zu erreichen, ist es vorteilhaft, wenn die Elektro­ den aus Streckmetall gebildet sind.The plastic housing is divided lengthways. Between Both halves are a seal when assembled intended. The plates of the electrodes are preferred made of platinum or platinum-plated titanium. For a better one re whirling of the inflow over the distribution room and the passage chamber to the flow of what flows To achieve it, it is advantageous if the electrical which are made of expanded metal.

Der Erfindung liegt die Aufgabe zugrunde, durch eine be­ sonders keimtötende Ausrüstung von Dentalgeräten die In­ fektionsgefahr für Arzt und Patient zu reduzieren. Die Lösung nach der Erfindung soll folgende Anforderungen erfüllen:
unschädlich gegenüber dem Patienten,
hohe Wirksamkeit gegen pathogene Keime, Pilze und Bakterien,
ortsunabhängige Wirkung und
Verträglichkeit der oxidierenden Substanz mit dem wirksamen Stoff. The invention has for its object to reduce the risk of infection for doctor and patient by a particularly germicidal equipment of dental devices. The solution according to the invention should meet the following requirements:
harmless to the patient,
high effectiveness against pathogenic germs, fungi and bacteria,
location-independent effect and
Compatibility of the oxidizing substance with the active substance.

Die der Erfindung zugrundeliegende Aufgabe wird gemäß den kennzeichnenden Merkmalen der Patentansprüche ge­ löst. Dabei handelt es sich nicht um eine reine Kombi­ nation von mikrobizider Ausrüstung der Kunststoffe und oxidativer Entkeimung, sondern um eine präzise Abstim­ mung der einzelnen Komponenten.The object underlying the invention is according to the characterizing features of the claims ge solves. It is not a pure station wagon nation of microbicidal equipment of plastics and oxidative disinfection, but a precise tuning of the individual components.

Der Vorteil der Erfindung liegt darin begründet, daß in allen Fällen die Grenzwerte der Trinkwasserverordnung eingehalten werden, eine vollständige Entkeimung im Zu­ führungskanal erfolgt und in den anderen Bereichen Bak­ terien und Pilze weitgehend abgetötet werden.The advantage of the invention is that in the limit values of the Drinking Water Ordinance in all cases be complied with, complete disinfection in the room channel and in the other areas Bak terie and fungi are largely killed.

Für die kurzzeitige oxidative Entkeimung des Wassers wird zunächst eine Chlorung, Ozonisierung oder direkte elektrochemische Behandlung zum Beispiel anodische Oxi­ dation, vorgenommen. Den Vorzug erhält dabei die elek­ trochemische Methode, weil die dazu nötige Vorrichtung ins Gerät eingebaut werden kann. Es handelt sich dabei um die bekannte Elektrolysezelle, die aus Chloridionen Chlor erzeugt oder mit direkter anodischer Oxidation die Keime tötet (siehe zum Beispiel: A. Reis, Anodische Oxi­ dation in der Wasser-und Lufthygiene, Verlag GIT, Darm­ stadt, 1981). Besonders im letzten Fall wird häufiger Elektrodenkontakt durch einen langen Weg des Wassers durch die Elektrolysezelle ermöglicht.For the brief oxidative disinfection of the water chlorination, ozonization or direct electrochemical treatment, for example anodic oxi dation, made. The elek trochemical method because the necessary device can be built into the device. These are the well-known electrolytic cell made of chloride ions Chlorine produces or with direct anodic oxidation Kills germs (see for example: A. Reis, Anodische Oxi dation in water and air hygiene, publisher GIT, Darm city, 1981). Especially in the latter case it becomes more common Electrode contact through a long path of water made possible by the electrolytic cell.

Die Chlorerzeugung muß unter dem für die Trinkwasserauf­ bereitungsverordnung zulässigen Niveau von 0,1 ... 0,6 mg/l liegen und darf auch nicht die mikrobiziden Zusätze zerstören. Die Chlorung wirkt besonders gegen pathogene Keime, wie zum Beispiel Hepatitis-Viren.The chlorine production must be below that for the drinking water preparation regulation permissible level of 0.1 ... 0.6 mg / l are and must not be the microbicidal additives to destroy. Chlorination is particularly effective against pathogenic ones Germs, such as hepatitis viruses.

Die langzeitige Entkeimung wird erreicht durch einen mikrobiziden Zusatzstoff, der in alle wasserführenden Leitungen und Systeme zum Beispiel die Schlauchmateria­ lien, eingearbeitet wird. Er erfüllt folgende Forderun­ gen: er wandert aus den verwendeten Schlauch-Kunststoffen wie Silikonharz, Polyamid, Polyurethan, Polypropylen, Lacke in einer wirksamen Konzentration genügend schnell aus,
die wirksame Konzentration liegt unter den nach der Trinkwasserverordnung zulässigen Grenzwerten,
Verarbeitungstemperaturen bis 250°C werden ohne Schädi­ gung überstanden,
der Wirkstoff wirkt gegen die meisten Bakterien und Pilze.Long-term disinfection is achieved through a microbicidal additive that is incorporated into all water-carrying pipes and systems, for example hose materials. It fulfills the following requirements: it migrates sufficiently quickly from the hose plastics used, such as silicone resin, polyamide, polyurethane, polypropylene, lacquers in an effective concentration,
the effective concentration is below the limit values permitted by the Drinking Water Ordinance,
Processing temperatures up to 250 ° C can be withstood without damage,
the active ingredient works against most bacteria and fungi.

Ein geeigneter Wirkstoff ist zum Beispiel 10, 10′-Phen­ oxybisarsin. Bei einer Konzentration von 0,02 bis 0,2% zugesetztem Wirkstoff werden die Grenzwerte nach der Trinkwasserverordnung von 50 µg/l weit unterschritten. Die Wirksamkeit ist selbst nach 6 Wochen Lagerung in Wasser von 60°C noch praktisch unverändert (Testkeime: Pseudomonas Putida, E-coli, Aspergillus niger, A. flavus, Penicillium funiculosum, Chaetomium globosum).A suitable active ingredient is, for example, 10, 10'-phen oxybisarsine. At a concentration of 0.02 to 0.2% added active ingredient, the limit values after the Drinking water regulation well below 50 µg / l. The effectiveness is in even after 6 weeks of storage Water of 60 ° C still practically unchanged (test germs: Pseudomonas Putida, E-coli, Aspergillus niger, A. flavus, Penicillium funiculosum, Chaetomium globosum).

Die Wirksamkeit läßt sich nach der in der Mikrobiologie üblichen Kulturmethode zum Beispiel auf der Basis des Hemmhoftestes nachweisen. Aus dem Hemmhof kann abgelei­ tet werden, daß die Besiedlung von Schlauch, Hohlräumen und Wasserkanal wirksam verhindert wird, wenn obenge­ nannte Methoden angewendet werden.The effectiveness can be compared to that in microbiology common culture method, for example, based on the Evidence of inhibition tests. From the inhibition yard can run off be that the colonization of hose, cavities and water channel is effectively prevented when above named methods are applied.

Im Bereich des Abwassers wird die wirksame Konzentration auf bis zu 0,5% 10, 10′-Phenoxybisarsin erhöht. Speischa­ le, Filter und Schläuche werden damit ausgerüstet. Mate­ rial: zum Beispiel Polypropylen, Alkydlacke, DD-Lacke. Durch die hohe Konzentration am Wirkstoff werden gleich­ zeitig auch die abgebohrten Zahnreste entkeimt.Effective concentration is in the area of wastewater increased to up to 0.5% 10, 10'-phenoxybisarsine. Speischa oils, filters and hoses are equipped with it. Mate rial: for example polypropylene, alkyd paints, DD paints. Because of the high concentration of the active ingredient, disinfected the drilled tooth remnants.

Mit 10, 10′-Phenoxybisarsin bis 0,2% werden auch die Gehäusewerkstoffe wie ABS (= Acrylnitril - Butadien- Styrol) oder Noryl (modifiziertes Polyphenylenoxid) oder Lacke ausgestattet. Andere handelsübliche Wirkstoffe zeigten bei diesen Werkstoffen keine Migrationsneigung. Die mikrobizide Ausrüstung der Kunststoffe hat neben der Verhinderung einer Besiedelung den Sinn, die Keimkonzen­ tration für die Elektrolysezelle zu reduzieren, weil mit der Zelle nur eine gewisse Menge an Keimen abgetötet wer­ den kann. Die Funktion der Zelle ist die wirksame Besei­ tigung pathogener Keime. Mit den Mikrobiziden können nur Bakterien und Pilze abgetötet werden.The housing materials such as ABS (= acrylonitrile - butadiene styrene) or noryl (modified polyphenylene oxide) or paints are also equipped with 10, 10′-phenoxybisarsine up to 0.2%. Other commercially available active substances showed no tendency to migrate with these materials. In addition to preventing colonization, the microbicidal treatment of the plastics has the purpose of reducing the concentration of germs for the electrolysis cell, because only a certain amount of germs can be killed with the cell. The function of the cell is the effective elimination of pathogenic germs. With the microbicides, only bacteria and fungi can be killed.
