A conveyor apparatus and a method for supplying amedicine-solution mixture from a plurality of medicine-activeingredient solutions and additional solutionconstituents in a body by means of a plurality of feeddevices is disclosed. The medicine-active ingredientsolutions have different medicine-active ingredientparameters and constituents； the solution constituents havedifferent parameters and constituents. The constituents ofat least two medicine-active ingredient solutions andsolution constituents are saved in at least one storagedevice； and are selected by means of one selection devicefor selection of at least one specific parameter and/orconstituent of each medicine-active ingredient solutionand/or the solution constituents. By means of a calculatingdevice, at least one additional parameter from all selectedparameters is calculated for the control and operation ofat least one additional feed device for supplying at leastone additional medicine-solution mixture to the body.
