Abstract

In an instrument oil based on mineral oil and/or vegetable oil for use in surgical and dental instruments and apparatus, in particular in the handles thereof, it is proposed to add cationic emulsifiers in order to improve the sterilisability of the instrument oil.

Description

Die Erfindung betrifft ein Instrumentenöl auf Mineralöl- und/oder Pflanzenölbasis zur Verwendung bei chirurgischen und zahnmedizinischen Instrumenten und Geräten, insbesondere bei deren Handstücken.The invention relates to an instrument oil Mineral oil and / or vegetable oil based for use for surgical and dental instruments and devices, especially in their handpieces.

Pflegemaßnahmen für chirurgische und zahnmedizinische Instrumente und Geräte schließen in der Regel nach der Reinigung eine Behandlung des Instruments oder Gerätes mit einem Instrumentenöl oder Schmiermittel ein. Danach erst wird eine Sterilisation durchgeführt, die vorzugsweise in einer Wasserdampfsterilisation besteht.Care measures for surgical and dental Instruments and devices usually close cleaning a treatment of the instrument or Device with an instrument oil or lubricant a. Only then is sterilization carried out preferably in a steam sterilization consists.

In letzter Zeit ist in der Fachliteratur des öfteren das Problem angesprochen worden, daß Instrumentenöle oder Schmiermittel ein Nährmedium oder einen Schutz für potentiell pathogene Keime darstellen können.Lately has been in the specialist literature quite often the problem has been raised that instrument oils or lubricant a nutrient medium or a protection for potentially pathogenic germs.

Es ist zwar bekannt, daß bei der Wasserdampfsterilisation auch dünne Schichten aus Öl, beispielsweise 10 µm dicke Ölfilme, unter üblichen Sterilisationsbedingungen keimfrei werden, ein besonderes Problem stellen jedoch die häufig vorhandenen Spalte in den Instrumenten und Geräten dar, die sich bei der Schmierung mit Öl füllen. Diese Volumina sind bei der Wasserdampfsterilisation für den Wasserdampf unzugänglich und stellen aus diesem Grunde ein nicht kalkulierbares Infektionsrisiko dar.It is known that in steam sterilization also thin layers of oil, for example Oil films 10 µm thick, under normal sterilization conditions becoming sterile, a particular problem  place the frequently existing columns in the Instruments and devices that are in the Fill the lubrication with oil. These volumes are at steam sterilization for water vapor inaccessible and therefore do not hire calculable risk of infection.

Um auch diese Schmiermittelanteile bei Verwendung von herkömmlichen Instrumentenölen sicher zu sterilisieren, müßten wesentlich höhere Sterilisiertemperaturen und längere Sterilisierdauern gewählt werden. Statt der bei der Wasserdampfsterilisation üblichen Temperatur von ungefähr 130°C bei 2 bar Druck müßte man auf Temperaturen von 180 bis 200°C erhitzen. Diese wesentlich höheren Temperaturen sind jedoch wegen den häufig in Instrumenten vorhandenen Kunststoffteilen problematisch und erfordern zudem einen höheren Energie- und Zeitaufwand.To also use these lubricant parts sterilize safely from conventional instrument oils, would need much higher sterilization temperatures and longer sterilization times can be selected. Instead of the usual for steam sterilization Temperature of about 130 ° C at 2 bar pressure to heat to temperatures of 180 to 200 ° C. However, these are much higher temperatures because of the plastic parts often found in instruments problematic and also require one higher expenditure of energy and time.

Neben den Instrumentenölen sind Konzentrate im Handel, die durch Verdünnung mit Wasser eine als Instrumentenmilch bezeichnete Wasser/Öl-Emulsion ergeben. Meist ist das verwendete Wasser nicht keimfrei, und die Emulsionen wirken geradezu als Nährbouillon für eine Keimproliferation. Eine Anwendung der üblichen Konservierungsstoffe zur Abtötung der Keime, wie z. B. Formaldehyd, Phenol und deren Derivate, scheidet aus, da diese Stoffe physiologisch bedenklich sind und die Schmierstoffe teilweise mit offenen Wunden in Kontakt kommen.
In addition to the instrument oils, concentrates are commercially available which, when diluted with water, give a water / oil emulsion called instrument milk. Most of the water used is not germ-free, and the emulsions act as a broth for germ proliferation. An application of the usual preservatives to kill the germs, such as. B. formaldehyde, phenol and their derivatives, is eliminated because these substances are physiologically questionable and the lubricants come into contact with open wounds.

Aufgabe der Erfindung ist es, ein Instrumentenöl zu schaffen, das auch in größerer Schichtdicke und an unzugänglichen Stellen mit Hilfe der herkömmlichen Wasserdampfsterilisation unter üblichen Bedingungen sicher sterilisiert werden kann.The object of the invention is to provide an instrument oil create that even in thicker layers and inaccessible places with the help of conventional Steam sterilization under normal conditions can be safely sterilized.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß dem Instrumentenöl kationaktive Emulgatoren zugesetzt sind.According to the invention, this object is achieved by that the instrument oil cationic emulsifiers are clogged.

Die kationaktiven Emulgatoren sorgen während der Wasserdampfsterilisation für eine gleichmäßige Wasseraufnahme und -verteilung im Instrumentenöl. Die bei der Wasserdampfsterilisation üblichen Temperaturen und Verweildauern im Autoklaven reichen damit für eine sichere Keimabtötung aus. Die kationaktiven Emulgatoren sind zudem thermisch stabil, so daß durch den Sterilisationsprozeß keine Zersetzung dieser Verbindungen eintritt.The cationic emulsifiers provide during the Steam sterilization for a uniform Water absorption and distribution in the instrument oil. The usual temperatures for steam sterilization and residence times in the autoclave are sufficient for safe germ killing. The cation active Emulsifiers are also thermally stable, so that by the sterilization process does not decompose it Connections occur.

Die Anteile der Emulgatoren im Instrumentenöl betragen vorzugsweise 1 bis 10 Vol.%.The proportions of the emulsifiers in the instrument oil are preferably 1 to 10% by volume.

Besondere thermische Stabilität, gute Emulgier- und Dispergierwirkung sowie gute biologische Abbaubarkeit und hervorragende Hautverträglichkeit weisen die Emulgatoren auf, die Derivate von Fettaminen bzw. Polyalkylaminen sind. Insbesondere haben sich Emulgatoren von Talgfettpropylendiamin bewährt. Diese sind wesentlich wirksamer als Ethoxylate von Fettalkoholen bzw. linearen aliphatischen Alkoholen (nichtionogene Tenside). Dies hängt mit ihrem polaren Charakter (kationische Tenside) zusammen. Bevorzugt werden Amin-Ethoxylate eingesetzt, die 3 Mol Ethylenoxid enthalten.Special thermal stability, good emulsification and Dispersing effect and good biodegradability and excellent skin tolerance Emulsifiers, the derivatives of fatty amines or Are polyalkylamines. Emulsifiers in particular have proven by tallow fat propylene diamine. These are much more effective than ethoxylates of fatty alcohols or linear aliphatic alcohols (non-ionic surfactants). This depends on her  polar character (cationic surfactants) together. Amine ethoxylates are preferably used which Contain 3 moles of ethylene oxide.

In dem Instrumentenöl kommt vorzugsweise reines Paraffinöl entsprechend den Spezifikationen des Deutschen Arzneimittelbuches (DAB 8) für dickflüssiges Paraffinöl zum Einsatz, wobei in speziellen Fällen physiologisch unbedenkliche Additive zur Erhöhung der Schmierwirkung und/oder zur Konservierung des Instrumentenöls zugesetzt sind. Die Schmierwirkung läßt sich insbesondere durch Zusatz von Triglyceriden von Fettsäuren mit C8- bis C10-Ketten mit einem Anteil von 5 bis 25 Vol.% erzielen. Mit diesen Stoffen lassen sich früher übliche Antiabriebsmittel vollständig ersetzen, so daß das Instrumentenöl nur noch aus physiologisch praktisch unbedenklichen Komponenten zusammengesetzt ist.Pure paraffin oil in accordance with the specifications of the German Medicinal Products Book (DAB 8) for viscous paraffin oil is preferably used in the instrument oil, with physiologically harmless additives for increasing the lubricating effect and / or for preserving the instrument oil being added in special cases. The lubricating effect can be achieved in particular by adding triglycerides of fatty acids with C 8 to C 10 chains in a proportion of 5 to 25% by volume. With these substances, conventional anti-abrasion agents can be completely replaced in the past, so that the instrument oil is only composed of physiologically practically harmless components.

Die nachfolgenden Testreihen zeigen die Verbesserung der Sterilisierbarkeit eines handelsüblichen Instrumentenöls durch die erfindungsgemäßen Amin- Ethoxylate.The following test series show the improvement the sterilizability of a commercially available Instrument oil by the amine Ethoxylates.

Die Untersuchungen wurden an einem Instrumentenmodell durchgeführt, welches aus zwei kreisrunden Metallplättchen mit 10 mm Durchmesser besteht, die durch eine Stahldrahtklammer aufeinander gepreßt werden und durch drei Vorsprünge auf einem Abstand von 0,1 mm gehalten sind. The investigations were carried out on an instrument model performed, which consists of two circular metal plates with a diameter of 10 mm, which consists of a steel wire clamp are pressed together and by three protrusions at a distance of 0.1 mm are kept.  

Das untere Plättchen wurde mit einer Suspension von Testsporen beschickt, anschließend mit dem Öl versehen und nach dem Aufsetzen des zweiten Plättchens im Autoklaven sterilisiert. Als Testsporen dienten in der Versuchsreihe A native Erdsporen, das Inokulum enthielt ca. 2,7 × 105 Keime pro Plättchen. Bei den Versuchsreihen B, C und D wurde Bacillus subtilis verwendet, pro Plättchen wurden ca. 5,3 × 106 Sporen aufgebracht. Die Sterilisationsbedingungen sind der Tabelle 1 zu entnehmen. Bei Versuch D wurde ein handelsübliches Sterilisationsgerät mit fraktioniertem Vakuum verwendet. Die sich an die Sterilisation anschließende Prüfung auf microbielles Wachstum erfolgte durch Überführen der Plättchen in ein Nährmedium (Trypticase-Soja-Bouillon (TSB)). In Kontrollexperimenten wurden die Plättchen nur mit den Sporen versehen, jedoch nicht mit Öl beschichtet und anschließend im Autoklaven sterilisiert.The lower plate was loaded with a suspension of test spores, then oiled and sterilized in the autoclave after placing the second plate. In test series A, native soil spores served as test spores; the inoculum contained approx. 2.7 × 10 5 germs per plate. In the test series B, C and D, Bacillus subtilis was used, about 5.3 × 10 6 spores were applied to each plate. The sterilization conditions are shown in Table 1. In experiment D, a commercial sterilizer with a fractionated vacuum was used. The microbial growth test following the sterilization was carried out by transferring the platelets into a nutrient medium (trypticase soy broth (TSB)). In control experiments, the platelets were only provided with the spores, but not coated with oil and then sterilized in an autoclave.

Als Öl wurde zunächst ein handelsübliches Instrumentenöl verwendet, dem in einer weiteren Versuchsreihe 10% des erfindungsgemäßen Instrumentenölzusatzes (Ethoxylat mit 3 Mol Ethylenoxid von Talgfettpropylendiamin) zugegeben wurde. Als Vergleich für die Wirkungsintensität diente eine Versuchsreihe mit einem entsprechenden Zusatz eines nichtionogenen Emulgators (Ethoxylat mit 5 Mol Ethylenoxid von linearen aliphatischen sekundären Alkoholen mit C12- bis C15-Ketten).A commercially available instrument oil was initially used as the oil, to which 10% of the instrument oil additive according to the invention (ethoxylate with 3 moles of ethylene oxide of tallow fat propylene diamine) was added in a further test series. A series of experiments with a corresponding addition of a nonionic emulsifier (ethoxylate with 5 mol ethylene oxide of linear aliphatic secondary alcohols with C 12 to C 15 chains) served as a comparison for the intensity of action.

Die Ergebnisse dieser Versuchsreihen sind in Tabelle 2 aufgelistet. Angegeben werden jeweils unsterile Proben zur Zahl der untersuchten Proben. In einem weiteren Kontrollexperiment wurden jeweils mit Keimen und Öl behandelte Plättchen hergestellt, die nicht sterilisiert wurden. Diese Proben zeigten stets ein bakterielles Wachstum (Ergebnisse sind nicht in Tabelle 2 enthalten).The results of these test series are in Table 2 listed. Non-sterile are given in each case  Samples for the number of samples examined. In one further control experiments were carried out with germs and oil-treated platelets that are not have been sterilized. These samples always showed one bacterial growth (results are not in Table 2 included).

Das Kontrollexperiment in Tabelle 2 zeigt, daß Plättchen, die nicht mit Öl beschichtet waren, nach der Sterilisierung zum Teil nicht ausreichend steril waren, was bedeutet, daß die Sterilisationsbedingungen insgesamt nur knapp ausreichend waren und sich jede Behinderung durch das Öl als vermehrtes Auftreten von unsterilen Proben zeigen mußte.The control experiment in Table 2 shows that Platelets that were not coated with oil sterilization is sometimes not sufficiently sterile were, which means the sterilization conditions overall were just barely sufficient and each Obstruction by the oil as an increased occurrence of non-sterile samples.

Aus der Tabelle 2, 3. Zeile kann eindeutig die Verbesserung der Sterilisationsfähigkeit des Instrumentenöles durch den erfindungsgemäßen Zusatz von kationaktiven Amin-Ethoxylaten abgelesen werden, da bei gleichen Sterilisationsbedingungen keine unsterilen Proben aufgetreten sind, im Gegensatz zu dem handelsüblichen Öl ohne diesen Amin-Ethoxylat-Zusatz und im Gegensatz zu dem handelsüblichen Öl mit einem anderen nichtionischen Ethoxylat-Zusatz.From table 2, 3rd line, the improvement can clearly be seen the sterilization ability of the instrument oil by the addition of cation-active according to the invention Amine ethoxylates can be read, because at same sterilization conditions no non-sterile Samples have occurred, in contrast to the commercially available Oil without this amine ethoxylate addition and in Contrary to the commercial oil with another non-ionic ethoxylate additive.

In einem Praxistest wurde schließlich die Schmierwirkung eines Öls mit dem erfindungsgemäßen Amin- Ethoxylat-Zusatz geprüft. Dabei konnte festgestellt werden, daß selbst bei der Zugabe von 10 Vol.% Amin- Ethoxylat die Erwärmung des getesteten Handstücks nur unwesentlich höher war als bei Verwendung des handelsüblichen Instrumentenöls. Die Unterschiede im Abrieb bei einer Schmierung mit handelsüblichem und erfindungsgemäßem Instrumentenöl waren ebenfalls gering.The lubricating effect was finally tested in a practical test an oil with the amine Ethoxylate addition checked. It was found that even with the addition of 10 vol.% amine Ethoxylate the warming of the tested handpiece was only slightly higher than when using the commercially available instrument oil. The differences  in abrasion with a lubrication with commercially available and instrument oil according to the invention were also low.

Insgesamt kann also festgehalten werden, daß die erfindungsgemäßen Amin-Ehtoxylat-Zusätze zum Instrumentenöl einerseits die Schmiereigenschaften des Instrumentenöls nicht beeinträchtigen und andererseits jedoch die Sterilisierbarkeit des Instrumentenöls so verbessern, daß bei den üblichen Bedingungen der Wasserdampfsterilisation mit einer sicheren Keimabtötung auch in Spalten und anderen dem Wasserdampf unzugänglichen Volumina der Instrumente und Handstücke gerechnet werden kann. Damit konnte eindeutig nachgewiesen werden, daß der erfindungsgemäße Amin- Ethoxylat-Zusatz die negativen Auswirkungen der Ölbeschichtung für den Dampfzutritt aufheben kann. Overall, it can be said that the Amine ethoxylate additives according to the invention for Instrument oil on the one hand the lubricating properties of the instrument oil and on the other hand however the sterilizability of the instrument oil so improve that under the usual conditions steam sterilization with safe germ killing also in crevices and other water vapor inaccessible volumes of instruments and handpieces can be expected. This could be clearly demonstrated be that the amine according to the invention Adding ethoxylate the negative effects of oil coating can pick up for steam access.
