Abstract
Description
Die Erfindung betrifft eine Wasseraufbereitungseinrichtung für medizinische Zwecke, insbesondere für Zahnbehandlungsstühle, an der mindestens ein Verbraucher angeschlossen ist.The invention relates to a water treatment device for medical purposes, in particular for dental chairs, to which at least one consumer is connected.
Wasser für medizinische Zwecke und hier insbesondere Wasser, das auch mit offenen Wunden in Berührung kommen kann, muss keimfrei sein, um eine mögliche Infektion des behandelten Patienten ausschließen zu können. Dies trifft auch für das Wasser bei zahnärztlichen Tätigkeiten zu. Dort wird Wasser außer zum Spülen des Mundes des Patienten auch als Kühlmittel für die verschiedenen zahnärztlichen Instrumente eingesetzt. Auch das als Kühlmittel eingesetzte Wasser muss absolut keimfrei sein, da bei Zahnbehandlungen häufig offene Wunden im Mund entstehen und eine Keimübertragung auf den Patienten durch das Kühlwasser nicht riskiert werden kann.Water for medical purposes, especially water, which may also come into contact with open wounds, must be germ-free in order to rule out possible infection of the treated patient. This also applies to the water in dental activities. There, water is also used as a coolant for the various dental instruments except to rinse the patient's mouth. Also, the water used as a coolant must be absolutely germ-free, since dental treatments often open wounds in the mouth and germ transmission to the patient by the cooling water can not be risked.
Um eine Übertragung von Keimen von Patient zu Patient zu vermeiden, wird bei medizinischen Verbrauchern häufig ein Desinfektionsmittel dem Wasser beigemischt. Diese können bei empfindlichen Patienten jedoch zu Nebenwirkungen führen. Bei den bisher eingesetzten Wasseraufbereitungssystemen kann jedoch ein Keimeintrag von der Wasserquelle her zu den Verbrauchern nicht sicher ausgeschlossen werden. Das aufbereitete Wasser wird häufig durch zu groß dimensionierte Wasserenthärtungsanlagen aufbereitet. Auf den Ionenaustauscherkerzen können sich Keime bilden. Dies gilt umso mehr, wenn nur geringe Mengen an Wasser durch das System hindurchfließen und nicht jeden Tag Wasser entnommen wird, wie dies bei Zahnbehandlungsstühlen der Fall ist.In order to avoid transmission of germs from patient to patient, a disinfectant is often added to the water in medical consumers. However, these can lead to side effects in sensitive patients. In the water treatment systems used hitherto, however, germination from the water source to the consumers can not be securely excluded. The treated water is often treated by oversized water softening systems. Germs can form on the ion exchange candles. This is even more so if only small amounts of water flow through the system and not every day water is removed, as is the case with dental chairs.
Die bisher bekannten Wasseraufbereitungsanlagen, die meist mit Ionenaustauschern und Vorfiltern ausgerüstet sind, gewährleisten eine Keimfreiheit nur in unzureichendem Maße.The previously known water treatment plants, which are usually equipped with ion exchangers and prefilters, ensure sterility only to an insufficient extent.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Wasseraufbereitungseinrichtung für medizinische Zwecke und hier insbesondere für Zahnbehandlungsstühle zu schaffen, bei der eine Übertragung von Keimen zu den Verbrauchern sicher vermieden werden kann.The present invention has for its object to provide a water treatment device for medical purposes and in particular for dental chairs, in which a transmission of germs to consumers can be safely avoided.
Die Aufgabe wird gelöst durch eine Wasseraufbereitungseinrichtung für medizinische Zwecke, insbesondere für Zahnbehandlungsstühle, an der mindestens ein Verbraucher angeschlossen ist und die mehrere Vorfilter und eine Umkehrosmoseeinrichtung aufweist, wobei der Umkehrosmoseeinrichtung mindestens eine nicht-chemische Entkeimungseinrichtung vorgeschaltet ist.The object is achieved by a water treatment device for medical purposes, in particular for dental treatment chairs, to which at least one consumer is connected and which has a plurality of prefilters and a reverse osmosis device, wherein the reverse osmosis device is preceded by at least one non-chemical sterilization device.
Umkehrosmoseeinrichtungen sind im Vergleich zu Ionenaustauschern deutlich leistungsfähiger und sorgen für eine maximale Entsalzung und Entkalkung des Wassers, was insbesondere für die Lebensdauer zahnärztlicher Instrumente von Bedeutung ist. Damit auch Viren sicher ausgesiebt werden können, ist vor der Umkehrosmoseeinrichtung mindestens eine Entkeimungseinrichtung, beispielsweise ein Ultrafilter angeordnet, dessen Filterfeinheit vorzugsweise zwischen 0,01 und 0,2 μm betragen kann. Durch diese Filterfeinheit kann gewährleistet werden, dass selbst Viren vom Filter zurückgehalten werden und dem Verbraucher ein keimfreies Wasser zur Verfügung steht. Statt Ultrafiltern könnten auch UV-Entkeimungseinrichtungen eingesetzt werden.Reverse osmosis devices are significantly more efficient compared to ion exchangers and ensure maximum desalination and descaling of the water, which is particularly important for the life of dental instruments. So that viruses can be safely screened out, at least one sterilization device, for example an ultrafilter, is arranged in front of the reverse osmosis device, the filter fineness of which may preferably be between 0.01 and 0.2 μm. Through this filter fineness can be ensured that even viruses are retained by the filter and the consumer a germ-free water is available. Instead of ultrafilters UV disinfection devices could also be used.
Wird nur relativ wenig aufbereitetes Wasser benötigt, wie dies beispielsweise bei Zahnbehandlungsstühlen der Fall ist, so können die Verbraucher, bei Zahnbehandlungsstühlen also die zu kühlenden Instrumente, und der Hahn zum Spülen des Mundes direkt an den Ausgang der Umkehrosmoseeinrichtung angeschlossen werden. Dies hat den Vorteil, dass sich nach der Umkehrosmoseeinrichtung kein stehendes Wasser mehr bilden kann, wodurch einer erneuten Verkeimungsgefahr wirksam begegnet werden kann.If only relatively poorly treated water is required, as is the case, for example, with dental chairs, then consumers, with dental chairs, the instruments to be cooled, and the tap for flushing the mouth can be connected directly to the outlet of the reverse osmosis device. This has the advantage that after the reverse osmosis device no stagnant water can form, whereby a renewed risk of contamination can be effectively counteracted.
Sind die zu entnehmenden Wassermengen jedoch größer, kann es von Vorteil sein, dass der Umkehrosmoseeinrichtung mindestens ein Wasservorratstank nachgeordnet ist. In diesem Fall kann zwischen dem mindestens einen Wasservorratstank und dem mindestens einen Verbraucher mindestens eine weitere nicht-chemische Entkeimungseinrichtung vorgesehen sein. Das im Vorratstank stehende Wasser neigt auch bei Edelstahlgefäßen zur erneuten Verkeimung. Wird jedoch ein Ultrafilter oder eine UV-Entkeimungseinrichtung zwischen den Wasservorratstank und den oder die Verbraucher geschaltet, so kann dies eventuell neu gebildete Keime ausfiltern. Das beim Verbraucher ankommende Wasser ist somit wieder keimfrei. Eine Wasseraufbereitungsanlage mit einem oder mehreren Wasservorratsbehältern kann beispielsweise in Zahnarztpraxen Verwendung finden, wenn mit der Wasseraufbereitung gleich mehrere Behandlungsstühle versorgt werden sollen.However, if the quantities of water to be withdrawn are greater, it can be advantageous for the reverse osmosis device to be arranged downstream of at least one water storage tank. In this case, at least one further non-chemical sterilization device can be provided between the at least one water storage tank and the at least one consumer. The standing in the storage tank water tends to re-germination even with stainless steel vessels. If, however, an ultrafilter or a UV sterilization device is connected between the water storage tank and the consumer or consumers, this may possibly filter out newly formed germs. The water arriving at the consumer is thus germ-free again. A water treatment plant with one or more water reservoirs can be used, for example, in dental practices, if the treatment of water to be treated several treatment chairs.
Bei beiden Lösungen, d. h. bei Anlagen mit und bei Anlagen ohne Wasservorratstank, kann außerdem vor dem oder den Verbrauchern ein Rückschlagventil vorgesehen sein, das eine Rückverkeimung der Wasseraufbereitungseinrichtung von der Verbraucherseite her verhindert.For both solutions, i. H. in systems with and in systems without water storage tank, may also be provided in front of the consumer or a check valve, which prevents re-contamination of the water treatment device from the consumer side.
Die in der Wasseraufbereitungseinrichtung vorgesehenen Vorfilter können unterschiedlich ausgestaltet und den jeweiligen Wasserversorgungsverhältnissen angepasst werden. So kann beispielsweise ein 50-μm-Filter zum Ausfiltern grober Schmutzpartikel vorgesehen sein. Zweckmäßigerweise kann außerdem ein Aktivkohlefilter und/oder ein feineres Filter mit beispielsweise 5 μm Filterfeinheit vorgesehen werden. Nach den Vorfiltern sind somit schon ein Großteil der Belastungen aus dem Wasser ausgefiltert, bevor dieses in das Ultrafilter und die Umkehrosmoseeinrichtung gelangt.The pre-filters provided in the water treatment device can be designed differently and adapted to the respective water supply conditions. For example, a 50 μm filter can be provided for filtering out coarse dirt particles. Conveniently, also an activated carbon filter and / or a finer filter with, for example, 5 micron filter fineness can be provided. After the pre-filters, therefore, a large part of the loads are filtered out of the water before it enters the ultrafilter and the reverse osmosis device.
Weitere entscheidende Vorteile ergeben sich, wenn die Wasseraufbereitungseinrichtung in einem austauschbaren Gehäuse angeordnet ist, an das der mindestens eine Verbraucher und eine Wasserversorgung anschließbar ist. Ist ein Wechsel eines der Filter notwendig, so wird einfach die gesamten Wasseraufbereitungsanlage ausgetauscht, sodass die Versorgung mit aufbereitetem Wasser nur für sehr kurze Zeit unterbrochen wird. In der entnommenen Anlage können die nicht mehr wirksamen Filter ausgetauscht und somit die Einsatzfähigkeit der Anlage wiederhergestellt werden. Diese Ausgestaltung der Wasseraufbereitungseinrichtung eignet sich für sämtliche medizinischen Geräte, die aufbereitetes Wasser benötigen, und insbesondere für Zahnbehandlungsstühle.Further decisive advantages arise when the water treatment device is arranged in a replaceable housing, to which the at least one consumer and a water supply can be connected. If a change of one of the filters is necessary, then simply the entire water treatment plant is replaced, so that the supply of treated water is interrupted only for a very short time. In the removed system, the no longer effective filters can be replaced and thus the operational capability of the system can be restored. This embodiment of the water treatment device is suitable for all medical devices that require treated water, and in particular for dental chairs.
Die Erfindung betrifft außerdem einen Zahnbehandlungsstuhl mit einer Wasseraufbereitungseinrichtung nach einem der Ansprüche 1 bis 8. In einem solchen Stuhl kann außerdem zusätzlich eine austauschbare, nicht-chemische Entkeimungseinrichtung integriert sein. Dadurch kann der Einsatz von Desinfektionsmitteln vermieden werden.The invention also relates to a dental treatment chair with a water treatment device according to one of
Nachfolgend werden zwei Ausführungsbeispiele einer erfindungsgemäßen Wasseraufbereitungsanlage anhand der Zeichnung näher beschrieben.Two embodiments of a water treatment plant according to the invention will be described in more detail with reference to the drawing.
