Description

Anwendungsgebiet der Erfindung:Field of application of the invention:

Die Erfindung kann überall dort angewendet werden, wo viele Gebrauchsgegenstände von immunschwachen Personengruppen berührt werden und die Gefahr einer Keimübertragung besteht. Das sind viele Gegenstände mit oft unbekanntem Infektionsrisiko wie Türklinken, Computertastaturen, Computermäuse, Haltegriffe im Autobus oder in der Bahn, Griffflächen einer Rolltreppe im Kaufhaus, Griffleisten am Einkaufswagen, Kopflehnen in Zügen, Telefonhörer, Klimaanlagen, Zahnbürsten, Lichtschalter, Geldschein und -münzen, Sporttaschen und Sportgeräte im Fitnesszentrum.The Invention can be everywhere be applied where many commodities of immunocompromised groups of people and the danger of a transmission of germs consists. These are many items with often unknown risk of infection such as door handles, computer keyboards, Computer mice, Grab handles on the bus or in the train, gripping surfaces of an escalator in the department store, Handle rails on the shopping cart, headrests in trains, telephone receivers, air conditioners, toothbrushes, Light switches, banknotes and coins, Sports bags and sports equipment in the Fitness center.

Bezugsstoffe für Alten- und Pflegeheime und Arztpraxen sowie Sporttaschen.Upholstery fabrics for the elderly and nursing homes and doctors' offices and sports bags.

Stand der Technik:State of the art:

Es gibt viele Gegenstände im täglichen Leben, die schnell hintereinander von den Händen mehrerer Personen berührt werden und damit zur Keimübertragung geeignet sind. In der Regel haben wir falsche hygienische Vorstellungen von unserer Umwelt. Nicht der Toilettensitz, sondern beispielsweise Türklinken, Computertastaturen, Computermäuse, Haltegriffe im Autobus oder in der Bahn, Griffflächen einer Rolltreppe im Kaufhaus, Griffleisten am Einkaufswagen, Kopflehnen in Zügen, Telefonhörer, Klimaanlagen, Zahnbürsten, Lichtschalter, Geldschein und -münzen, Sporttaschen und Sportgeräte im Fitnesszentrum, Mülleimereinsätze sind Keimträger und können Infektionen übertragen. Die Handhygiene ist eine wichtige Vorsorgemaßnahme, denn unsere Hände sind der häufigste Übertragungsweg. Speziell im Krankenhausbereich, in Arztpraxen und in Pflege- und Altenheimen, wo sich immungeschwächte Menschengruppen aufhalten, besteht ein Bedarf an infektionssicheren Gegenständen. Die Krankenhaushygiene setzt in erster Linie auf eine sachgemäße Desinfektion (z. B. Ethylenoxid, Formaldehyd, Aldehyde, Peressigsäure und Alkohole). Für den Privatbereich sollten keine chemischen Keulen eingesetzt werden, sondern es genügt bereits, die Keime an der Oberfläche des Kontaktbereiches auszudünnen (z. B. Sagrotan). Keime sind praktisch überall und nur wenige sind bei immungeschwächten Personen in der Lage, Infektionen (nosokominale Keime) auszulösen. Dennoch gibt es warnende Stimmen, dass eine völlig sterile Umwelt unser natürliches Immunsystem verkümmern lässt und die Anfälligkeit wird dann umso höher. Es ist folglich ratsam, ein zweites ergänzendes Immunsystem beispielsweise mit Silber aufzubauen.It are many things in the daily Lives that are touched in quick succession by the hands of several persons and thus for germ transmission are suitable. As a rule, we have wrong hygienic ideas from our environment. Not the toilet seat, but for example Doorknobs, Computer keyboards, computer mice, Grab handles on the bus or in the train, gripping surfaces of an escalator in the department store, Handle rails on the shopping cart, headrests in trains, telephone receivers, air conditioners, toothbrushes, Light switches, banknotes and coins, Sports bags and sports equipment in the Fitness center, trash cans are germ carrier and can Transmit infections. Hand hygiene is an important precaution because our hands are the most common transmission route. specially in hospitals, doctors' offices and nursing homes, where immunocompromised There is a need for infection-proofing Objects. Hospital hygiene focuses primarily on proper disinfection (For example, ethylene oxide, formaldehyde, aldehydes, peracetic acid and Alcohols). For the private sector should not use chemical maces, but it is enough already, the germs on the surface of the contact area thinned (eg Sagrotan). Germs are practically everywhere and only a few are in immunocompromised persons able to cause infections (nosokominale germs). Yet There are warning voices that a completely sterile environment is our natural one Immune the immune system lets and the vulnerability then gets higher. It is therefore advisable to have a second supplemental immune system, for example build up with silver.

Es gibt relativ wenig Zahlenmaterial über die Keimbedrohung mit Gegenständen aus dem persönlichen Leben. Eine Studie in Autobahn-Raststätten von 2004 wies unlängst nach, dass 13% mit Fäkalien und 1,6% mit pathogenen Keimen auf der Türklinke belastet war. Inzwischen gibt es sogar einen Reinigungsservice für Zahlungsmittel. In den USA werden beispielsweise Türklinken aller 15 min automatisch mit einem Desinfektionsmittel besprüht. Durch die Globalisierung benötigt ein Grippevirus nur wenige Tage zur Umrundung unseres Planeten.It Issues relatively little data on the germ threat of objects the personal Life. A study in motorway service areas from 2004 recently showed that 13% with feces and 1.6% was loaded with pathogenic germs on the doorknob. meanwhile There is even a cleaning service for means of payment. In the USA for example, doorknobs automatically sprayed every 15 minutes with a disinfectant. By globalization is needed a flu virus only a few days to orbit our planet.

Weiterhin ist bekannt, dass besonders Silber als Metall, Kolloid oder Ion eine keimtötende Eigenschaft aufweist, die neu entdeckt und durch den komplexen Angriff über die drei Ebenen (Enzyme werden funktionsuntüchtig, die Atmungskette wird unterbrochen und die Vermehrung der Erbsubstanz wird gestoppt) können sich keine Resistenzen durch wandlungsfähige Keime wie bei Antibiotika ausbilden.Farther It is known that especially silver as a metal, colloid or ion a germicidal Has property that rediscovered and through the complex attack over the three levels (enzymes become dysfunctional, the respiratory chain becomes interrupted and the multiplication of the genetic material is stopped) can become no resistance due to versatile germs as in antibiotics form.

Inzwischen gibt es bereits Verfahren zur Silberapplikation wie das Galvanikverfahren für Metalle (Messing und andere Legierungen), oder der Einsatz von Leitlacken für Kunststoff und zuletzt der Einsatz von Lacken mit Nanosilber. Letzteres behindert die Bakterienvermehrung und ihre Lebensfähigkeit, ohne eine absolute Sterilität zu erzielen. Wegen der hohen Oberfläche von Nanopartikeln sind nur geringe Konzentrationen notwendig (wenige 100 ppm), um bei Erhalt der Materialeigenschaft die Materie vor bakterieller Zerstörung durch Bakterien und Pilze zu schützen.meanwhile There are already methods for silver application such as the electroplating process for metals (brass and other alloys), or the use of conductive paints for plastics and finally the use of paints with nanosilver. The latter hinders Bacterial multiplication and its viability without an absolute sterility to achieve. Because of the high surface area of nanoparticles only low concentrations necessary (a few 100 ppm) in order to receive the material property the matter from bacterial destruction Protect bacteria and fungi.

Ziel der Erfindung:Object of the invention:

Ziel der Erfindung ist die Keimverdünnung auf den Gegenständen, die oft durch mehrere immungeschwächte Personen berührt werden. Eine Vollsterilisation ist oft nicht erwünscht, jedoch eine Verdünnung der Keimbesiedlung Erfindungsgemäß geschieht das in der Weise, dass nur eine sehr dünne Auflage an Silber entweder auf metallischen Gegenständen bzw. Kunststoffen unter Verwendung von Leitlacken galvanisch aufgetragen werden oder es werden nanosilberhaltige Silberlacke eingesetzt. Besonders dort, wo Temperaturen um 25–30°C und eine hohe Feuchte vorliegt, wird die Keimvermehrung begünstigt, denn die meisten Bakterien bis auf Sporenbildner benötigen zur Vermehrung eine hohe Wasseraktivität (0,6–0,998). Das ist gegeben bei Zahlungsmitteln in der Geldbörse, denn hier herrschen Vermehrungsbediungungen (37%, 28°C).aim The invention is the germ dilution the objects, which are often touched by several immunocompromised persons. Full sterilization is often undesirable, but a dilution of the Germination According to the invention happens that in the way that only a very thin layer of silver either on metallic objects or plastics using lead coatings galvanically applied be or nanosilver silver paints are used. Especially where temperatures are around 25-30 ° C and high humidity, the germ multiplication is favored, because most bacteria except spore formers need to Propagate a high water activity (0.6-0.998). That is given with means of payment in the purse, because here reproductive conditions prevail (37%, 28 ° C).
