Abstract
Description
Die Erfindung betrifft eine Krankenwaschvorrichtung mit einer in ein Bett einlegbaren wasserundurchlässigen Kunststoffolie, deren Ränder allseits unter Bildung einer Wanne hochgezogen und gegen Umknicken verstärkt bzw. gesichert sind, einer Zuleitung zur Wanne und einem Abfluß.The invention relates to a medical washing device a waterproof plastic film that can be inserted into a bed, the edges of which form a tub pulled up and reinforced or secured against twisting are, a feed line to the tub and a drain.
Eine gattungsgemäße Krankenwaschvorrichtung ist beispielsweise aus dem deutschen Gebrauchsmuster 88 11 746 bekannt.A generic sick washing device is for example known from German utility model 88 11 746.
Derartige Krankenwaschvorrichtungen werden dann eingesetzt, wenn ein Tansport einer kranken oder immobilen Person schwierig oder unmöglich ist und eine Reinigung bzw. Körperpflege stationär im Krankenbett vorgenommen werden muß. Insbesondere Kranke, die großflächige Hautverletzungen oder offene Wunden aufweisen, können nur schwierig transportiert werden und müssen daher in derartigen Waschvorrichtungen gewaschen werden.Such washing devices are then used if a transport of a sick or immobile person is difficult or impossible and cleaning or personal hygiene must be carried out in the hospital bed. Especially sick people who have extensive skin injuries or open wounds are difficult to transport are and must therefore be in such washing devices getting washed.
Bei den bekannten Waschvorrichtungen bestanden die Kunststoffteile, also beispielsweise die als Wanne dienende Kunststoffolie bzw. die Kunststoffteile der Zuleitung und des Abflusses üblicherweise aus einem Polyvinylchlorid-Kunststoff (PVC), der jedoch entscheidende Nachteile aufweist. Zum einen sind derartige Kunststoffe nicht oder nur schlecht sterilisierbar, da sie nicht kochfest bzw. chemisch nicht ausreichend beständig sind. Bei den üblichen Sterilisationsverfahren entweichen aus diesen Kunststoffen die normalerweise zugesetzten Weichmacher, so daß die Kunststoffolien einerseits leicht verspröden und andererseits im Laufe der Zeit eine hohe Oberflächenporosität aufweisen, die dazu führt, daß sich in den Microporen Bakterien und andere Krankheitskeime festsetzen.In the known washing devices, the plastic parts for example, the one that serves as a tub Plastic film or the plastic parts of the supply line and the drain usually made of a polyvinyl chloride plastic (PVC), which has decisive disadvantages. On the one hand, such plastics are not or only difficult to sterilize as they are not boil-proof or chemical are not sufficiently stable. With the usual sterilization processes escape from these plastics normally added plasticizer so that the plastic films slightly brittle on the one hand and Have a high surface porosity over time, which leads to bacteria and others in the micropores Fix disease germs.
So kam es bei den bisher verwendeten Krankenwascheinrichtungen häufig zu Infektionen, die ihre Einsatzmöglichkeiten im klinischen Gebrauch stark einschränkten.So it came with the previously used medical washing facilities often lead to infections that can be used in severely restricted clinical use.
Darüber hinaus kann es selbst dann zu Infektionen kommen, wenn die Kunststoffolie bzw. die Kunststoffteile der Zuleitung bzw. des Abflusses ausreichend steril sind. Es ist nämlich nicht sichergestellt, daß das zum Waschen verwendete Wasser völlig keimfrei ist. In den Armaturen der Wasserleitung können sich trotz der üblichen Reinigungsmaßnahmen Krankheitskeime festsetzen, die beim Waschen vom Wasser mitgerissen werden und den Patienten infizieren können. Auch bei der Verwendung von mobilen Servicetanks besteht diese Gefahr.In addition, infections can occur even if the plastic film or the plastic parts of the supply line or the drain are sufficiently sterile. It is namely not ensured that the used for washing Water is completely germ-free. In the fittings of the water pipe can despite the usual cleaning measures Fix disease germs when washing from water get carried away and infect the patient. Also this exists when using mobile service tanks Danger.
Eine weitere Infektionsquelle ist durch das dem Abfluß zugeführte Brauchwasser gegeben, das in Kontakt mit dem Patienten war. Dieses Wasser kann mit Krankheitskeimen durchsetzt sein, die vom Patienten stammen und zu einer Ansteckung anderer Personen führen, wenn geringe Mengen von Aerosolen des meist warmen Waschwassers frei werden oder Wasser beim Anschließen des Abflusses an einen Entsorgungstank oder eine übliche Abwasserleitung verspritzt wird.Another source of infection is that of the drain Given service water that is in contact with the patient was. This water can be infused with pathogens be from the patient and become contagious lead to other people if small amounts of aerosols of the mostly warm washing water or water when connecting the drain to a disposal tank or a common sewage pipe is splashed.
Der Erfindung liegt die Aufgabe zugrunde, eine Krankenwaschvorrichtung zu schaffen, bei der die Gefahr einer Infektion für den Patienten oder sonstige Personen verringert ist.The invention has for its object a medical washing device to create at the risk of infection is reduced for the patient or other persons.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kunststoffolie und/oder die Kunststoffteile der Zuleitung und des Abflusses aus einer Polyorganosiloxan-Verbindung oder einem hochvernetzten fluorierten Kunststoff besteht und/oder in der Zuleitung und/oder dem Abfluß keimtötende Filter, vorzugsweise in Form von UV-C-Strahlern, vorgesehen sind.This object is achieved in that the Plastic film and / or the plastic parts of the supply line and the drain from a polyorganosiloxane compound or a highly cross-linked fluorinated plastic and / or germicidal in the supply line and / or the drain Filters, preferably in the form of UV-C emitters, are provided are.
Die erfindungsgemäß verwendeten, auch als Silikone bezeichneten Kunststoffe, sind gegenüber den bisher gebräuchlichen Kunststoffen zwar etwas teurer, sie weisen jedoch hinsichtlich ihrer Gebrauchseigenschaften im klinischen Bereich, insbesondere bei der Heiß- bzw. chemischen Sterilisation, enorme Vorzüge gegenüber den bekannten, üblicherweise verwendeten Kunststoffen auf. Die Silikone, insbesondere die Silikonkautschuke gemäß Anspruch 2 bzw. 3 weisen eine Temperaturbeständigkeit bis ca. 250 °C auf, so daß sie wiederholt problemlos mit den bekannten Heiß-Sterilisationsverfahren sterilisiert werden können, ohne daß Weichmacher oder ähnliche flüchtige Verbindungen austreten können und auf der Oberfläche der Kunststoffe Poren entstehen.Those used according to the invention, also referred to as silicones Plastics are compared to the previously used Plastics are a little more expensive, but they show in terms of their use properties in the clinical area, especially with hot or chemical sterilization, enormous advantages over the known, commonly used Plastics. The silicones, especially the Silicone rubbers according to claim 2 or 3 have a temperature resistance up to about 250 ° C so that it repeats easily with the known hot sterilization processes can be sterilized without plasticizers or the like volatile compounds can leak and on the Surface of the plastic pores arise.
Auf diese Weise ist bei den erfindungsgemäßen Krankenwaschvorrichtungen bei entsprechender Lagerung eine absolute Keimfreiheit zu erreichen, so daß keine Infektionsgefahr für die betroffenen Kranken besteht.In this way, the inventive washing devices with appropriate storage an absolute To achieve sterility, so that no risk of infection for the affected patient exists.
Auch für chemische Sterilisationsverfahren sind die erfindungsgemäßen Krankenwaschvorrichtungen hervorragend geeignet, da sie gegen die dort eingesetzten keimabtötenden Wirkstoffe aufgrund ihrer chemischen Zusammensetzung weitestgehend beständig sind.The inventive ones are also for chemical sterilization processes Excellent for washing the sick, because they fight the germicidal agents used there largely because of their chemical composition are stable.
Die Temperaturbeständigkeit des Silikonkautschuks läßt sich ggf. durch den Einbau verschiedener Zusatzstoffe in das Kunststoffgefüge erhöhen. So können z.B. die Methylgruppen durch Fluoralkylgruppen ersetzt werden oder Carboraneinheiten eingebaut werden. The temperature resistance of the silicone rubber can be if necessary by incorporating various additives into the Increase the plastic structure. For example, the methyl groups be replaced by fluoroalkyl groups or carborane units to be built in.
Neben der Verwendung von Kunststoffen auf Siloxanbasis können für den vorgesehenen Verwendungszweck auch generell fluorierte Kunststoffe eingesetzt werden, die aufgrund ihrer hohen Vernetzung eine vergleichsweise hohe Temperaturbeständigkeit und chemische Widerstandsfähigkeit aufweisen.In addition to the use of siloxane-based plastics also generally for the intended use fluorinated plastics are used because of their high networking a comparatively high temperature resistance and have chemical resistance.
Durch die Verwendung von in die Zuleitung und/oder den Abfluß der Krankenwaschvorrichtung eingebauten keimtötenden Filtern, insbesondere UV-Strahlern, kann eine weitere Infektionsgefahr sicher verhindert werden. Als UV-Strahler werden vorzugsweise die bekannten Quecksilberdampflampen eingesetzt, die nach außen abgeschirmt sind und mittels UV-durchlässiger Rohr- bzw. Schlauchleitungsteile das möglicherweise keimhaltige Wasser bestrahlen können.By using in the supply line and / or the drain the germ washing device built into the sick washer Filtering, especially UV lamps, can pose a further risk of infection can be prevented safely. As a UV lamp preferably the known mercury vapor lamps used, which are shielded from the outside and UV-permeable Pipe or hose line parts possibly can irradiate germ-containing water.
Zum Abpumpen des gebrauchten Waschwassers wird zweckmäßigerweise eine sogenannte Schlauchpumpe eingesetzt, die mit dem Inneren der Schlauchleitung nicht in Berührung kommt und daher nicht sterilisiert werden muß. Das gleiche gilt für die Zuleitung, wenn z.B. das Zuleitungswasser einem separaten Servicetank entnommen werden soll.For pumping out the used washing water, it is expedient a so-called peristaltic pump used with the Inside the hose line does not come into contact and therefore does not need to be sterilized. The same applies the supply line if e.g. the supply water to a separate Service tank should be removed.
