An infusion system for administering multiple medical fluids to a patient comprises: a multiplicity of infusion devices (20, 30); an organization device (2, 3) comprising a multiplicity of slots (201-208) for receiving the multiplicity of infusion devices (20, 30); and a control device (7) for controlling an infusion operation of the multiple infusion devices (20, 30), the control device (7) comprising a storage device (73) for storing infusion parameters to control the infusion operation of the multiplicity of infusion devices (20, 30). Herein, the storage device (73) stores information relating to a desired allocation of at least a portion of the multiplicity of infusion devices (20, 30) to the slots (201 -208) of the organization device (2, 3), wherein the control device (7) is constituted, for setting up the infusion operation, to provide instructions to a user (U), according to the desired allocation, how to allocate the infusion devices (20, 30) to the slots (201- 208) of the organization device (2, 3). In this way an infusion system for administering multiple medical fluids to a patient is provided which facilitates the set-up of an infusion operation for a user in particular when multiple medical fluids shall be administered to a patient using multiple different infusion devices at the same time.La présente invention concerne un système de perfusion pour administrer des fluides médicaux multiples à un patient qui comprend : une pluralité de dispositifs de perfusion (20, 30) ; un dispositif d'organisation (2, 3) comprenant une pluralité de logements (201-208) pour recevoir la pluralité de dispositifs de perfusion (20, 30) ; et un dispositif de commande (7) pour commander une opération de perfusion des dispositifs de perfusion multiples (20, 30), le dispositif de commande (7) comprenant un dispositif de stockage (73) pour stocker des paramètres de perfusion pour commander l'opération de perfusion de la pluralité de dispositifs de perfusion (20, 30).
