System for regulating the concentration of glucose in the blood of a person and use of such a system

A system for regulating the concentration of glucose in the blood of a person, said system comprising:

• a device for selectively supplying at least two substances, said device comprising:
• at least two receiving spaces for accommodating at least two reservoirs containing said substances;
• at least two ports for connecting to a respective transport element, and
• a controller for controlling said device such that a certain amount of said substance is supplied and thereby infused into the body of the person via a respective infusion set,
• at least two infusion sets, each infusion set comprising:
• an infusion element comprising an infusion means for infusing a substance into a body of said person, said infusion means comprising an inlet end for receiving said substance and an outlet end for infusing said substance into said body, wherein said infusion element comprises a first connector for connecting to a second connector of a transport element of the infusion set, and
• said transport element comprising a transport means, a second connector arranged at an outlet end of the transport means that is connectable to said first connector of said infusion element such that in a connected condition in which the second connector of the transport element is connected to the first connector of the infusion element a medium through flow connection is provided between the outlet end of the transport means and the inlet end of the infusion means for feeding the substance to the infusion means, and a third connector arranged at an inlet end of the transport means for connecting to said port such that in a connected condition in which the third connector is connected to said port a medium through flow connection is provided between said reservoir accommodated in said receiving space and the inlet end of the transport means for receiving said substance from said reservoir,
• wherein said system comprises a mischannelling detection system for detecting mischannelling of the infusion element and transport element and/or for detecting mischannelling of the transport element and port, and wherein said controller is arranged for controlling said device to not supply said substance and/or to provide a warning signal to said person if mischannelling is detected.
