Die Erfindung bezieht sich auf einen Prüfkörper für die Prüfung des Reinigungsvorgangs von medizinischen Instrumenten und insbesondere von chirurgischen Instrumenten.The invention relates to a test body for testing the cleaning process of medical instruments and in particular surgical instruments.
Medizinische Instrumente, wie beispielsweise Endoskope, Scheren, Zangen, Skalpelle etc. werden in speziellen medizinischen Reinigungsgeräten gereinigt und gegebenenfalls desinfiziert. Ein Beispiel für derartige Reinigungsgeräte sind die handelsüblichen Waschdesinfektionsautomaten.Medical instruments such as endoscopes, scissors, forceps, scalpels, etc. are cleaned and, if necessary, disinfected in special medical cleaning devices. An example of such cleaning devices are commercially available washing and disinfection machines.
Diese Reinigungsgeräte weisen in der Regel Siebschalen auf, in die die Instrumente eingelegt werden.These cleaning devices usually have sieve trays into which the instruments are placed.
Weitgehend unabhängig von dem speziellen Aufbau des jeweiligen Reinigungsgeräts und der verwendeten Siebschalen ist problematisch, daß durch die spezielle Formgebung des Instruments, Verschmutzungen des Geräts etc. der Reinigungserfolg unterschiedlich ausfallen kann.Largely independent of the specific design of the respective cleaning device and the sieve bowls used, the problem is that the cleaning success can vary due to the special shape of the instrument, contamination of the device, etc.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, die die Überprüfung des Reinigungserfolges erlaubt.The invention is based on the object of providing a device which allows the checking of the cleaning success.
Erfindungsgemäß wird ein Prüfkörper für die Prüfung des Reinigungsvorgangs von medizinischen Instrumenten und insbesondere von chirurgischen Instrumenten geschaffen, der ein Trägerteil, das so geformt ist, daß es in eine Siebschale des Reinigungsgerätes einlegbar oder an einer Sieb-According to the invention, a test body for testing the cleaning process of medical instruments and in particular of surgical instruments is created, which has a carrier part which is shaped in such a way that it can be inserted into a sieve tray of the cleaning device or attached to a sieve

schale anbringbar ist, und ein Testplättchen aufweist, das an dem Trägerteil gehalten ist. Das Testplättchen weist eine Testverschmutzung auf, die es einer Bedienungsperson für das Reinigungsgerät erlaubt, nach Beendigung des Reinigungsvorgangs den Reinigungserfolg beispielsweise visuell zu überprüfen. Selbstverständlich ist es aber auch möglich, den Reinigungs- bzw. Desinfektionserfolg automatisiert zu überprüfen.bowl and has a test plate that is held on the carrier part. The test plate has a test contamination that allows an operator of the cleaning device to check the cleaning success, for example visually, after the cleaning process has been completed. Of course, it is also possible to check the cleaning or disinfection success automatically.
Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben: Further developments of the invention are specified in the dependent claims:
So kann das Trägerteil Ausnehmungen aufweisen, mit denen es an den Draht der Siebschalen anklemmbar ist. Diese Ausbildung hat den vorteil, daß sie „möglichst" wirklichkeitsgetreu die Verhältnisse bei der Reinigung bzw. Deinfektion eines medizinischen Instruments simuliert.The carrier part can have recesses with which it can be clamped to the wire of the sieve trays. This design has the advantage that it simulates the conditions during the cleaning or disinfection of a medical instrument as realistically as possible.
Unabhängig davon, wie der Prüfkörper in dem Gerät gehalten wird, ist es weiterhin von Vorteil, wenn das Trägerteil wenigstens eine Abwinklung bevorzugt wenigstens zwei Abwinklungen - aufweist, die auf gegenüberliegenden Seiten des Testplättchens angeordnet sind aufweist, durch die der durch Gelenke, Kröpfungen etc. hervorgerufene Spülschatten bei medizinischen Instrumenten simuliert wird.Regardless of how the test specimen is held in the device, it is furthermore advantageous if the carrier part has at least one bend - preferably at least two bends - which are arranged on opposite sides of the test plate, by means of which the rinsing shadow caused by joints, bends, etc. in medical instruments is simulated.
Weiterhin ist es von Vorteil, wenn das Trägerteil aus einem Kunststoff besteht, da dann nur weniges Verschmutzungen an ihm anhaften, so daß das Trägerteil die weiteren in dem Reinigungsgerät befindlichen Instrumente nicht kontaminieren kann. Besonders bevorzugt ist es, wenn das Trägerteil aus einem durchsichtigen Kunststoff besteht, da dann der Reinigungserfolg auf beiden Seiten des Testplättchens ohne Abbau des Testplättchens kontrolliert werden kann.It is also advantageous if the carrier part is made of plastic, as only a small amount of dirt will adhere to it, so that the carrier part cannot contaminate the other instruments in the cleaning device. It is particularly preferred if the carrier part is made of transparent plastic, as the cleaning success can then be checked on both sides of the test plate without dismantling the test plate.

Durch die Ausbildung des Trägerteils als Spritzgußteil insbesondere aus Makroion erhält man ein vergleichsweise kostengünstig herzustellendes Teil.By forming the carrier part as an injection-molded part, particularly from Makrolon, a part is obtained that is comparatively inexpensive to produce.
Bei dem Testplättchen andererseits ist es besonders bevorzugt, wenn dieses aus einem Metall und insbesondere Edelstahl besteht. Bei einer derartigen Materialwahl lassen sich nicht entfernte Verschmutzungen besonders einfach visuell feststellen.On the other hand, it is particularly preferred for the test plate to be made of metal, particularly stainless steel. With this type of material, it is particularly easy to visually detect any contamination that has not been removed.
Das Testplättchen kann dabei von dem Trägerteil abnehmbar sein. Insbesondere ist e» hierzu möglich, Testplättchen in Ausnehmungen in dem Trägerteil einzusetzen.The test plate can be removable from the carrier part. In particular, it is possible to insert test plates into recesses in the carrier part.
Weiterhin können die Abmessungen des Testplättchens etwa t5 * 50 mm betragen.Furthermore, the dimensions of the test plate can be approximately t5 * 50 mm.
Die Erfindung wird nachstehend ohne Beschränkung des allgemeinen Erfindungsgedankens anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung exemplarisch beschrieben, auf die im übrigen hinsichtlich der Offenbarung aller im Text nicht näher erläuterten erfindungsgemäßen Einzelheiten ausdrücklich verwiesen wird. Es zeigen:The invention is described below without limiting the general inventive concept using exemplary embodiments with reference to the drawing, to which reference is expressly made with regard to the disclosure of all inventive details not explained in more detail in the text. They show:

Das in Fig. 1 gezeigte Trägerteil weist eine Grundplatte 1 mit zwei Abwinklungen 2 auf, in denen Ausnehmungen 3 vorgesehen sind, mit denen es an den Draht der Siebschalen eines nicht dargestellten Reinigungsgeräts anklemmbar ist.The carrier part shown in Fig. 1 has a base plate 1 with two angled portions 2 in which recesses 3 are provided, with which it can be clamped to the wire of the sieve bowls of a cleaning device (not shown).
Die Abwinklungen simulieren den durch Gelenke, Kröpfungen etc. hervorgerufenen Spülschatten bei medizinischen Instrumenten.The bends simulate the rinsing shadow caused by joints, bends, etc. on medical instruments.
Fig. 2 zeigt, daß in das Trägerteil ein Testplättchen 4 einklemmbar ist, das beispielsweise aus Stahl und insbesondere einer für medizinische Instrumente verwendeten Stahlsorte besteht, und auf dem eine Testverschmutzung aufbringbar ist.Fig. 2 shows that a test plate 4 can be clamped into the carrier part, which consists for example of steel and in particular of a type of steel used for medical instruments, and on which a test contamination can be applied.
Das Testplättchen 4 und die Grundplatte 1 schließen einen Winkel ein, so daß ihr Abstand unterschiedlich ist. Hierdurch ist es möglich, den Reinigungserfolg für unterschiedlich große Zwischenräume visuell zu kontrollieren. Die optische Kontrolle wird dadurch erleichtert, daß das Trägerteil aus einem durchsichtigen Kunststoff, beispielsweise Makroion besteht.The test plate 4 and the base plate 1 form an angle so that their distance is different. This makes it possible to visually check the cleaning success for gaps of different sizes. The visual inspection is made easier by the fact that the carrier part is made of a transparent plastic, for example Makrolon.
Zusätzlich ist das Testplättchen abnehmbar; hierdurch wird ebenfalls die optische Kontrolle erleichtert.In addition, the test plate is removable, which also makes visual inspection easier.
