Abstract: The invention relates to an arrangement and a method for preparing a formulation for parenteral nutrition. In more detail the invention relates to a mixing system for parenteral nutrition, comprising at least two containers, wherein the at least two containers form a modular system. The mixing system comprises a septum, which is pierceable by a spike or a needle and a hanger for attaching the mixing system to an infusion rack. A first container comprises a male connector and a second container comprises a female connector, which fit together. First and second container can be coupled together, thereby forming a channel, which enables the passage of liquid and the mixing of the ingredients of the containers.

Abstract: Container for a mixing system being filled with liquid parenteral nutrition and comprising a male connector and a female connector. The male connector is placed on the opposite side of the container compared to the female connector and the male connector and the female connector are embodied to be mechanically engageable with each other and to engage a mechanical connection with a male connector or a female connector respectively of another container and to form a channel, which enables the passage of liquid. At least two containers form a modular system for parenteral nutrition.
