摘要:
The present invention provides methods of coating or impregnating medical devices with an antiseptic composition that will inhibit or prevent the nosocomial infections typically associated with the use of such medical devices. The present invention further provides methods of coating or impregnating medical devices that produce devices with effective activity against infection, while avoiding destroying the devices or causing the devices to become toxic. In addition, the invention provides medical devices coated or impregnated with antiseptic compositions by the aforementioned novel methods.
摘要:
A composition for rendering materials fluorescent substantially without visible trace comprises an organic fluorescent compound dissolved in a solvent characterized by a boiling point or distillation range at atmospheric pressure of between about 12.degree.-35.degree. C. The preferred composition comprises fluorescent azoles, such as 2-(o-Hydroxyphenyl)benzoxazole, 2-(o-Hydroxyphenyl)benoxazole, and derivatives thereof dissolved in volatile halocarbon solvents, such as Fluorotrichlormethane, 1,1-Dichloro-1-Fluoroethane, and 2,2-Dichloro-1,1,1-Trifluoroethane. The resultant product is particularly suited for marking currency, papers, fabrics, and other porous webs and surfaces. Treated surfaces appear normal in white light, are highly fluorescent under UV light and feature excellent transfer of the fluorescent compound to fingertips and other surfaces in direct or glancing contact.
