A medical device having a surface with car disinfection effect

To reduce the risk of infection in the medical facilities, it is proposed for a medical device (6, 7) with a potentially contaminatable surface (10, 15) an auto disinfecting effect of the surface (10, 15) to produce. For this purpose the surface (10, 15) with a coating (11, 16) is provided, consisting essentially containing graphene oxide or graphene oxide composite material, or the surface (10) comprehensive component of the medical device (7) is made from a graphene containing composite material manufactured.
