Abstract

A powdery fluorescent pigment is suspended as detection agent in a detergent and/or disinfectant. In order to detect the use of the detergent and/or disinfectant on a surface to be treated, the surface is irradiated by means of a U.V. light source that reveals at least traces of detection agent.

Description

Verfahren zum Nachweis der Behandlung einer Oberfläche mit einem Reinigungs- und/oder Desinfektionsmittel Process for the detection of the treatment of a surface with a cleaning and / or disinfectant
Die Erfindung betrifft ein Nachweisverfahren für die Anwendung eines Reinigungs- und/oder Desinfektionsmittels. Insbesondere im medizinischen Bereich ist die regelmäßige Reinigung und Desinfektion der Oberfläche von Gegenständen aller Art unerläßlich. Für die Kontrolle des Reinigungsgrades ist es mehrfach bekannt, Mittel einzusetzen, die die Anwesenheit von Verschmutzungsrückständen detektieren, und beispielsweise eine direkt oder etwa unter UV-Licht erkennbare Verfärbung bewirken (EP-A 347 494, WO-A 90/14591 , WO-A 92/06671 , WO 93/19152), wobei die Detektionsmittel getrennt oder auch gleichzeitig mit dem Reinigungs- oder Desinfektionsmittel aufgetragen werden. Die Detektion der Verunreinigungen erfordert natürlich, daß die Detektionsmittel mit den Verunreinigungen reagieren können, d.h. für spezielle Verunreinigungen spezielle Detektionsmittel notwendig sind.The invention relates to a detection method for the use of a cleaning and / or disinfectant. Regular cleaning and disinfection of the surface of objects of all kinds is essential, especially in the medical field. To check the degree of cleaning, it is known several times to use agents which detect the presence of contamination residues and, for example, cause discoloration which can be recognized directly or approximately under UV light (EP-A 347 494, WO-A 90/14591, WO-A 92/06671, WO 93/19152), the detection means being applied separately or simultaneously with the cleaning agent or disinfectant. Detection of the contaminants naturally requires that the detection means can react with the contaminants, i.e. special detection agents are required for special contaminants.
Von Ausnahmen abgesehen, in denen eine Sterilität des gesamten Bereichs erforderlich ist, ist es häufig vor allem von Interesse, ob eine Reinigung bzw. Desinfektion der Oberfläche durchgeführt wurde und nicht versehentlich unterblieben ist, sowie welcher Zeitraum seit der letzten Behandlung der Oberfläche vergangen ist.Apart from exceptions in which sterility of the entire area is required, it is often of primary interest whether the surface has been cleaned or disinfected and has not been inadvertently omitted, and what time has elapsed since the last treatment of the surface.
Die Erfindung schlägt hiefür ein Nachweisverfahren vor, das die Behandlung der Oberfläche bei einer Bestrahlung mit Licht erkennbar macht, in dem zumindest Reste eines mit dem Reinigungs- und/oder Desinfektionsmittels vermischten Detektionsmittels sichtbar werden. Das Detektionsmittel enthält insbesondere einen Fluoreszenzfarbstoff, der durch UV-Bestrahlung sichtbar wird. Erfindungsgemäß wird also nicht der Reinigungsgrad geprüft und die Anwesenheit von verbliebenen Verunreinigungen, sondern die Anwesenheit des Reinigungs- und/oder Desinfektionsmittels festgestellt, wobei je nach Flüchtigkeit des Reinigungs- und/oder Desinfektionsmittels oder des Detektionsmittels ersichtlich wird, daß die letzte Behandlung mit dem Mittel innerhalb einer bestimmten Zeitspanne erfolgt ist.For this purpose, the invention proposes a detection method which makes it possible to detect the treatment of the surface when irradiated with light, in which at least residues of a detection agent mixed with the cleaning and / or disinfecting agent become visible. The detection means contains, in particular, a fluorescent dye which is visible through UV radiation. According to the invention, it is not the degree of cleaning that is checked and the presence of remaining impurities, but rather the presence of the cleaning agent and / or disinfectant, which, depending on the volatility of the cleaning and / or disinfectant or the detection agent, shows that the last treatment with the agent has occurred within a certain period of time.
So kann beispielsweise ein Arzt in seiner Ordination dem jeweils folgenden Patienten in einfacher Weise darlegen, daß er zwischenzeitlich seine Hände gereinigt und desinfiziert hat, in dem er die Hände unter eine UV-Lampe hält, die das Detektionsmittel zum Aufleuchten bringt. Speziell in diesem Fall hätte die Darstellung verbliebener Verunreinigungen mittels des Detektionsmittels nach dem Stand der Technik genau den gegenteiligen Effekt, und eine rückstandsfreie Reinigung könnte auch nicht dargelegt werden, da ja dann nichts sichtbar würde. Eine Überprüfung, ob eine Reinigung bzw. Desinfektion von Geräten und Werkzeugen oder von Arbeitsflächen erfolgt ist, ist in gleicher Weise möglich. Weiters kann auf diese Weise auch amtlichen Kontrollen eindeutig belegt werden, daß ein Reinigungs- und/oder Desinfektionsmittel angewendet worden ist.For example, a doctor in his office can simply explain to the following patient that he has meanwhile cleaned and disinfected his hands by holding his hands under a UV lamp that lights up the detection means. Especially in this case the representation would have remaining contaminants by means of the detection means according to the prior art have exactly the opposite effect, and a residue-free cleaning could also not be demonstrated, since then nothing would be visible. A check whether cleaning or disinfection of devices and tools or work surfaces has taken place is possible in the same way. Furthermore, official controls can be clearly demonstrated in this way that a cleaning and / or disinfectant has been used.
Nachstehend werden zwei Beispiele für ein erfindungsgemäßes Nachweisverfahren näher beschrieben.Two examples of a detection method according to the invention are described in more detail below.
Für die Reinigung von Oberflächen wird eine wässerige Seifenlösung mit einem pulverigen Leuchtpigment, beispielsweise einem Yttriumoxidsulfid vermischt. Für eine Desinfektion einer Oberfläche wird 2-Propanol mit einem pulverigen Leuchtpigment, beispielsweise Yttriumoxid vermischt. In beiden Fällen verbleiben Reste des suspendierten Leuchtpigments auf der Oberfläche, das unter UV-Bestrahlung luminisziert. Die Luminiszenz verringert sich unter Tageslichteinfluß und endet spätestens 6 Stunden nach der Anwendung. For cleaning surfaces, an aqueous soap solution is mixed with a powdery luminous pigment, for example an yttrium oxide sulfide. To disinfect a surface, 2-propanol is mixed with a powdery luminous pigment, for example yttrium oxide. In both cases, residues of the suspended luminous pigment remain on the surface, which luminesces under UV radiation. Luminance decreases under the influence of daylight and ends at the latest 6 hours after application.
