Abstract

In order to create a process and a device for the monitoring and control of the flow of material in a hospital it is provided for the units generating the flow of material to each be provided with their own individual identification, for this individual identification to be read at various transit stations in the hospital, the read data of the individual identification and the transit stations to be fed to a central monitoring and control unit, stored and/or processed in it and for monitoring signals or control signals controlling the flow of material to be generated as a function of the stored and/or processed data.
