Tube nozzle for a respirator

A medical system comprising:

• a medical device with a medical device inductance for generating an electromagnetic field and a writing and/or reading module;
• an accessory with an accessory inductance for generating an electromagnetic field and a semiconductor chip;
• and
• a coupling device for mechanically and electromagnetically coupling the medical device with the accessory, the coupling device comprising a mechanical coupling means for mechanically coupling the medical device with the accessory, a coupling device inductance, a capacitance and an electric line to form an electric circuit as a resonant circuit for the electromagnetic coupling of the inductance at the medical device with the inductance at the accessory and with a semiconductor chip for storing and/or processing at least one piece of information and/or for sending and/or receiving at least one signal.
