Abstract
Abstract A medical instrument (11) has a main body (12), on which surface at least one antimicrobial agent is located. The antimicrobial agent is selected from the group consisting of N-(fluorodichloromethylthio)-phthalimide, 2-(4-thiazolyl)-benzimidazole, N,N-dimethyl-Nʹ-phenyl-(N-fluorodichloromethylthio)-sulphamide, 2,4,5,6-tetrachloroisophtharonitrile, parachlorometaxylenol, sodium 2-pyridinethiol-1-oxide, zinc 2-pyridinethiol-1-oxide, and 2,4,4ʹ-trichloro-2ʹ-hydroxyphenyl ether, and suppresses the increase of microorganisms contacting the surface of the main body (12).

Claim 1
Independent Claim
56 words
A medical instrument comprising: a main body of the medical instrument; and at least one antimicrobial agent located on at least a surface of the main body and selected from the group consisting of N-(fluorodichloromethylthio)-phthalimide, 2-(4-thiazolyl)-benzimidazole, N,N-dimethyl-Nʹ-phenyl-(N-fluorodichloromethylthio)-sulphamide, 2,4,5,6-tetrachloroisophtharonitrile, parachlorometaxylenol, sodium 2-pyridinethiol-1-oxide, zinc 2-pyridinethiol-1-oxide, and 2,4,4ʹ-trichloro-2ʹ-hydroxyphenyl ether, wherein the increase of microorganisms contacting the surface is suppressed.
