Abstract
Alcohol solution containing fluorescein for visualization of hygienic hand disinfection also contains a refatting agent and wetting agent. An Independent claim is also included for a test kit for visualization of hygienic hand disinfection, consisting of this alcohol solution and a 365 nm ultraviolet (UV) lamp, which can be used in a darkened room or with darkened articles.
Description
Technisches Gebiet
Die Anwendung des visualisierenden Testkits empfiehlt sich im medizinisch/pharmazeutischen Bereich und in der Lebensmittelverarbeitung. Darüber hinaus überall dort, wo aus hygienischen Gründen eine Desinfektion der Hände mit alkoholischen L²sungen eingesetzt wird (z.B. Labors).
Stand der Technik
Die Händedesinfektion mit alkoholischen L²sungen ist das anerkannte Verfahren zur Abt²tung von Krankheitserregern auf den Händen. Mit der Desinfektion wird eine Keimübertragung innerhalb Einrichtungen des Gesundheitswesens oder des Lebensmittelbereiches angestrebt, um die daraus entstehenden Krankenhausinfektionen bzw. Keimübertragungen auf Lebensmittel zu minimieren. Das in den genannten kritischen Bereichen tätige Personal muss für eine korrekte Händedesinfektion geschult werden, da die Einreibetechnik eine wesentliche Voraussetzung für eine effiziente Keimabt²tung darstellt. Zu Schulungszwecken wurden bisher Händeabklatsch mittels Agarplatten durchgeführt. Dabei werden die Hände oder Fingerspitzen auf einer Nähragarplatte abgedrückt und das Bakterienwachstum beurteilt. Dieses mikrobiologische Verfahren erfordert eine 24-stündige Bebrütung der Agarplatten.
Die Ergebnisse sind deshalb nicht sofort an der Schulung verfügbar und bewerten nur einen Ausschnitt der Hände. Gemäss der Recherche durch das Eidgen²ssische Institut für geistiges Eigentum befinden sich fluoreszierende L²sungen auf dem Markt, die eine Benetzung von Haut- und Schleimhäuten nach Desinfektion darstellen (z.B. vor operativen Eingriffen). Nicht aber solche mit Fluorescein und solche, die für Schulungen/Gewerbe für die hygienische Händedesinfektion eingesetzt werden.
Detaillierte Darstellung der Erfindung
Die vorliegende Erfindung betrifft die Schulung von medizinischem oder anderem Personal in der Technik der hygienischen Händedesinfektion. Erfunden wurde eine Formulierung einer fluoreszierenden, alkoholischen L²sung für Hände und Haut im Zusammenhang mit einer technischen M²glichkeit, die Benetzung schnell und gut sichtbar darzustellen. Alkohol (Ethanol 63 Gewichts% und Aqua 37 Gew.%) wurde mit fluoreszierendem Farbstoff (Fluorescein 0,1 Gew.%), einem Rückfetter (Propylenglykol 0,5 Gew.%) und Netzmittel (Tween 80, 0,5 Gew.%) versetzt. Die bisherige L²sung enthielt nur Ethanol und Fluorescein (in anderen Konzentrationen). Die Formulierung wurde dadurch wesentlich verbessert. Damit sich die gefärbte L²sung auf der Hand gut verteilen kann, wurde sie mit Tween angereichert (Netzmittel).
Damit keine Austrocknung der Haut entsteht, wurde das Mittel mit Rückfetter (Propylenglykol) versetzt Damit sich die Benetzung der Hände und Haut noch besser darstellt, wurde die Konzentration des fluoreszierenden Farbstoffes (Fluorescein) verändert. Die mit Alkohol benetzte Haut kann mithilfe einer UV-Lampe in einem verdunkelten Raum oder in einer Schaukiste oder hnlichem dargestellt werden. Dabei fährt man mit einer UV-Lampe (365 nm (nanoMeter) Wellenlänge) über die Hände und stellt die benetzten Hautareale hellgelb dar, die nicht mit Alkohol benetzten Stellen dunkelviolett. Bei den Schulungen sind häufig die Fingerspitzen, Handrücken, Daumen und Fingerzwischenräume nicht ausreichend benetzt. Eine Schulung mit diesem Test zeigt nachweislich eine Verbesserung des Verhaltens bei der Händedesinfektion.
Die geschulten Personen verbrauchen zwei- bis dreimal mehr Händealkohol (eigene Untersuchungen, C. Conrad).
Ausführung der Erfindung
Ethanol absolutum wird mit Aqua (Endkonzentration 70% V/V) versetzt. Hinzugefügt wird Fluorescein Natrium 0,1%, Propylenglykol 0,5% und Tween 80 0,5%.
Technische Details über die UV-Lampe
365 nanoMeter Wellenlänge, nur für kurzzeitigen Einsatz geeignet (Schulungen), da es bei Dauereinsatz zu Hautschäden kommen kann.
Technical field
The use of the visualizing test kit is recommended in the medical / pharmaceutical sector and in food processing. In addition, wherever hygienic reasons use hand disinfection with alcoholic solutions (e.g. laboratories).
State of the art
Hand disinfection with alcoholic solutions is the recognized method for killing pathogens on the hands. Disinfection aims to transmit germs within healthcare or food facilities in order to minimize the resulting hospital infections and germ transmission to food. The personnel working in the above-mentioned critical areas must be trained for correct hand disinfection, since the rub-in technique is an essential prerequisite for efficient germ screening. So far, clapping of hands with agar plates has been carried out for training purposes. The hands or fingertips are pressed on a nutrient agar plate and the bacterial growth is assessed. This microbiological process requires a 24-hour incubation of the agar plates.
The results are therefore not immediately available at the training and only evaluate a section of the hands. According to research by the Swiss Federal Institute of Intellectual Property, there are fluorescent solutions on the market that represent wetting of the skin and mucous membranes after disinfection (e.g. before surgery). But not those with fluorescein and those that are used for training / trade for hygienic hand disinfection.
Detailed description of the invention
The present invention relates to the training of medical or other personnel in the technique of hygienic hand disinfection. A formulation of a fluorescent, alcoholic solution for hands and skin was invented in connection with a technical possibility of displaying the wetting quickly and clearly. Alcohol (ethanol 63% by weight and aqua 37% by weight) was mixed with fluorescent dye (fluorescein 0.1% by weight), a refatting agent (propylene glycol 0.5% by weight) and wetting agent (Tween 80, 0.5% by weight ) offset. The previous solution only contained ethanol and fluorescein (in other concentrations). This significantly improved the wording. So that the colored solution can be distributed well on the hand, it was enriched with Tween (wetting agent).
To prevent the skin from drying out, the agent has been treated with lipid replenishing agent (propylene glycol). In order to improve the wetting of the hands and skin, the concentration of the fluorescent dye (fluorescein) has been changed. The skin wetted with alcohol can be displayed using a UV lamp in a darkened room or in a showcase or similar. You drive a UV lamp (365 nm (nanoMeter) wavelength) over your hands and show the wetted areas of the skin in light yellow, the areas not wetted with alcohol are dark purple. During the training, the fingertips, back of the hand, thumb and spaces between fingers are often not adequately wetted. Training with this test demonstrably shows an improvement in behavior in hand disinfection.
The trained people consume two to three times more hand alcohol (own research, C. Conrad).
Implementation of the invention
Absolute ethanol is mixed with aqua (final concentration 70% v / v). Fluorescein sodium 0.1%, propylene glycol 0.5% and Tween 80 0.5% are added.
Technical details about the UV lamp
365 nanoMeter wavelength, only suitable for short-term use (training), since permanent use can damage the skin.
