Disinfectant dispenser for storing and delivering an agent for disinfecting surfaces and/or skin, disinfectant and method for publically signalling a disinfected state of persons
The invention relates to a disinfectant dispenser for storing and delivering an agent for disinfecting surfaces and/or skin, to a disinfectant and to a method for publicly signalling a disinfected state of persons. The disinfectant dispenser comprises: a first storage container with a disinfectant contained therein； a second storage container with a marking substance contained therein, the marking substance being inactive inside the second storage container； and a mixing section, in which the marking substance is mixed with the disinfectant when the disinfectant dispenser is actuated, the marking substance becoming active after the delivery step from the disinfectant dispenser. The disinfectant consists of a disinfecting basic component and a marking substance that can be admixed with the basic component, the marking substance being inactive before it is admixed with the disinfecting basic component and once admixed, and after application of the disinfectant to a surface, the marking substance marking the disinfected surface by a colouring, so that it is noticeable to the human eye and can be detected by technical means. The marking effect vanishes as the disinfected state diminishes. The method for publicly signalling a disinfected state of persons comprises the steps: application of a disinfecting mixture consisting of a disinfecting component and a marking component to an area of skin that should be disinfected, at a disinfecting station； colouring of the area of skin that should be disinfected by the marking component during the disinfection step； a resultant visible persistence of the colouring on the disinfected area of skin, the disinfected state of the area of skin being generally noticeable and detectably signalled； and a fading persistence of the colouring, at the latest as the sterility of the skin area diminishes, a resultant discolouration or change in colour being likewise generally noticeable and detectably signalled.
