Abstract
A medical device has a fluid port (2), a tube (20), a socket (4), which can be connected to the fluid port and to the tube with freely selectable rotation positions. The tube is provided with a transponder (22) and with a writing and reading device for communication with the transponder, which has an antenna (24) in the area of the fluid port. The socket is provided with a coil (5, 6) each, whose axis of rotation is directed essentially coaxially to the axis of rotation about which the relative rotation position of the socket is variable. The two coils are connected by electric lines (8), to which at least one capacitor (9) is connected as a circuit component. The coils, the electric lines and the circuit component form an electric oscillatory circuit for transmitting signals between the writing and reading device and the transponder.
