Medical device with a fluid port

摘要

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.

主权项

1. A medical device comprising:
a fluid port; a tube; a socket part having a socket part first connection end for connection to said fluid port with freely selectable socket part rotation positions about a socket part first end axis and having a socket part second connection end for connection to said tube with freely selectable socket part rotation positions about a socket part second end axis to establish a fluid connection between said fluid port and said tube; a transponder provided at an end of said tube at which said tube is connected to said socket; a writing and reading device for communication with said transponder, said writing and reading device having an antenna in an area of said fluid port; a first coil fixed to said socket and disposed rotationally symmetrical in an area of said first connection end essentially coaxial to said first end axis; a second coil fixed to said socket and disposed rotationally symmetrical in an area of said second connection end essentially coaxial to said second end axis; an electric line connecting said first coil and said second coil; a capacitor connected to said electric line as a circuit component, wherein said first coil, said second coil, said electric line and said circuit component form an electric oscillatory circuit for transmitting signals from the writing and reading device to said transponder and vice versa independently from a relative rotational position of the socket in the fluid port and also independently from a relative rotational position of the socket relative to the tube.
