Abstract
Description
Die Erfindung betrifft ein Prüfsystem zur Kontrolle der Reinigungsleistung von Wasch-/Desinfektions- und Reinigungsautomaten.The The invention relates to a test system to control the cleaning performance of washing / disinfecting and Cleaning machines.
Im Zuge der minimal invasiven Medizintechnik werden immer mehr rohr- oder schlauchartige Hohlkörper zur Diagnostik oder chirurgischer Korrektur eingesetzt. Der Vorteil der minimal invasiven Medizintechnik liegt eindeutig in der Vermeidung oder Minimierung von Traumata, die den Heilungsprozess verzögern und auch den Patienten unnötig belasten.in the As part of minimally invasive medical technology, more and more tube or tubular hollow bodies used for diagnosis or surgical correction. The advantage The minimally invasive medical technology is clearly in the avoidance or minimizing trauma that delays the healing process and also unnecessary for the patient strain.
Unvermeidbar ist eine Kontaminierung sowohl auf den Außen- als auch auf den Innenflächen der rohr- bzw. schlauchartigen Instrumente mit Körperflüssigkeiten. Diese Körperflüssigkeiten können Sekrete, Gewebsflüssigkeit aber auch Blut sein, die beispielsweise mit Viren oder auch Bakterien jeglicher Art kontaminiert sein können.Unavoidable is a contamination on both the outer and the inner surfaces of the tubular or tubular instruments with body fluids. These body fluids can secretions, lymph but also be blood, for example, with viruses or bacteria of any kind can be contaminated.
Vor bzw. nach einem minimal invasiven Eingriff werden die Instrumente in der Regel in Waschautomaten gereinigt und desinfiziert.In front or after a minimally invasive procedure the instruments become usually cleaned and disinfected in washing machines.
Während das Wasch- und Reinigungsergebnis auf den Außenseiten der Instrumente recht einfach durch eine Sichtprüfung kontrolliert werden kann, stellt sich diese Sichtprüfung für die Innenseiten der Hohlkörper bedeutend schwieriger bis unmöglich dar, da diese Instrumente nur wenige Millimeter Innendurchmesser aufweisen können, jedoch ihre Länge bei einigen Metern liegen kann.While that Washing and cleaning result on the outside of the instruments right simply by a visual inspection can be controlled, this visual inspection turns out for the insides the hollow body significantly more difficult to impossible because these instruments are only a few millimeters inside diameter can have however, their length can be at a few meters.

Aufgabe der vorliegenden Erfindung ist es, ein Prüfsystem zur Kontrolle der Reinigungsleistung von Waschautomaten im speziellen für minimal invasive Instrumente zu entwickeln, bei dem ein Prüfsystem es ermöglicht den Reinigungsvorgang praxisnah zu simulieren und zu interpretieren, wobei vorrangig die Einfachheit der Bedienung des Prüfkörpers und eine möglichst geringe Fehlerquote durch den Anwender (z.B. verwechseln der Testanschmutzung mit einer bakteriellen Kontamination, etc.) zu realisieren ist. Gleichzeitig soll eine Rekontamination der gereinigten bakteriell kontaminierten Testträgern durch das Personal verhindert werden, da das Prüfsystem erst im auswertenden Labor geöffnet werden muss.task It is the object of the present invention to provide a test system for controlling the cleaning performance of Washing machines in special for to develop minimally invasive instruments using a testing system allows to simulate and interpret the cleaning process in practice priority being the simplicity of operation of the test specimen and a preferably low error rate by the user (for example confusing the test stain) with bacterial contamination, etc.). At the same time, a recontamination of the purified bacterially contaminated test carriers be prevented by the staff, since the test system only in the evaluating Laboratory opened must become.
Diese
Aufgabe wird erfindungsgemäß dadurch
gelöst,
dass Prüfsystem
aus mindestens zwei aufeinander abgestimmten Gehäuseteilen (
Sinnvollerweise ist der Leitungsgraben an einer Seite mit einem Anschluss versehen, der es erlaubt über eine Schnittstelle mit der Medienzufuhr des Wasch- und Reinigungsautomaten verbunden zu werden. Vorzugsweise ist dieser Anschluss als Luer-Lock Anschluss ausgebildet.Logically, the trench is provided with a connection on one side, who allows it over an interface with the media supply of the washing and cleaning machine to be connected. Preferably, this port is a luer lock Connection formed.
Das Wasch- und Reinigungsmediums wird über den Zulauf des Prüfsystems in den Leitungsgraben eingeleitet, über- bzw. umspült die Testanschmutzung bzw. die bakterielle Kontamination und fließt über den Ablauf aus dem Prüfsystem. Weist das Prüfsystem nach dem Waschvorgang keine Unreinheiten mehr auf, kann davon ausgegangen werden, dass auch im Inneren der minimal invasiven Instrumente keine Verschmutzung mehr vorhanden ist. Voraussetzung ist, dass es sich bei der Testanschmutzung um eine Verschmutzung handelt, die sich in der Regel zumindest gleichschwierig entfernen lässt wie die typischerweise in minimal invasiven Instrumenten anhaftenden Verschmutzungen wie Blut, Körpersekrete, etc.The washing and cleaning medium is introduced via the inlet of the test system into the trench, overflows or surrounds the test soil or the bacterial contamination and flows out of the test system via the outlet. If the test system no longer shows any impurities after the washing process, it can be assumed that there is no more contamination inside the minimally invasive instruments. The prerequisite is that the test soiling is a soiling that can usually be removed at least as difficult as the contaminants typically found in minimally invasive instruments, such as Blood, body secretions, etc.
Der
in das Gehäuseteil
(
Durch das Einarbeiten des Leitungsgraben in das Gehäuseteil wird eine sehr kompakte Bauweise realisiert. Der Leitungsgraben liegt geschützt im Inneren des Gehäuses und ist gegen äußere Beschädigungen optimal geschützt.By the incorporation of the trench in the housing part is a very compact Construction realized. The trench is protected inside of the housing and is against external damage optimally protected.
Ebenfalls vorteilhaft ist es das Prüfsystem aus einem durchscheinenden Material herzustellen, da dann das Prüfsystem nach dem Waschvorgang nicht geöffnet werden muss um die Testanschmutzung zu begutachten.Also Advantageously, it is the test system a translucent material, because then the test system not open after the washing process must be to assess the test soil.
Grundsätzlich können wahlweise
die Gehäuseteile
so gestaltet sein, dass sie die Möglichkeit bieten, sich sowohl
vor als auch nach dem Waschvorgang öffnen und schließen zu lassen,
um an Testanschmutzung (
Eine weitere Variante stellt sich derart dar, dass auf einen Prüfkörper ausschließlich in einer Testkammer verzichtet werden kann und die Testanschmutzung zusätzlich über den kompletten Leitungsgraben verteilt eingebracht ist. Dies bietet die Möglichkeit eine Verschmutzung eines minimal invasiven Instrumentes korrekt wiederzuspiegeln, da bei diesen Instrumenten die Verschmutzung nicht definiert an einer bestimmten Stelle des Instrumentes zu finden sind, sondern, wie bei den zu reinigenden Instrumenten auch, über die komplette Länge des Instruments bzw. Schlauchs.A Another variant is such that on a specimen exclusively in a test chamber can be omitted and the test soiling additionally over the complete trench is introduced distributed. This offers the possibility contamination of a minimally invasive instrument is correct again, because pollution is not present in these instruments defined to find at a specific location of the instrument but, as with the instruments to be cleaned, over the complete length of the instrument or hose.
Ebenfalls sinnvoll erscheint es, das Prüfsystem für den Einweggebrauch mit einem maschinenlesbaren fortlaufenden Code zu versehen, da so eine eindeutige Rückführbarkeit der Prüfsystems bis hin zum Herstellungsprozess des Prüfsystems gewährleistet ist.Also it makes sense, the test system for the Disposable with a machine-readable continuous code too provided, as a clear traceability of the test system guaranteed up to the manufacturing process of the test system is.
