Device and method for the authentication of a user of a medical device

A treatment system for treating a patient, comprising:

• a medical device, and
• a portable authentication device, wherein
• the medical device and the portable authentication device are adapted to communicate wirelessly with each other,
• the medical device is adapted to wirelessly transmit a signal containing a signal corresponding to an acoustic signal when a wireless communication connection is successfully established between the medical device and the portable authentication device,
• the portable authentication device is adapted to receive the signal containing the signal corresponding to the acoustic signal, to generate, based on the received signal, an acoustic signal corresponding to the signal corresponding to the acoustic signal, and to output the generated acoustic signal to the medical device, and
• the medical device is adapted to determine whether or not the portable authentication device is located at a position where acoustic communication between the medical device and the portable authentication device is possible, depending on whether or not it receives the acoustic signal.

• the medical device is adapted to determine whether or not the portable authentication device is located at a position where acoustic communication between the medical device and the portable authentication device is possible, depending on whether or not it receives the signal indicating that the portable authentication device has received the acoustic signal.

A treatment system for treating a patient, comprising:

• a medical device, and
• a portable authentication device, wherein
• the medical device and the portable authentication device are adapted to communicate wirelessly with each other,
• the portable authentication device is adapted to output a predetermined acoustic signal, when a wireless communication connection between the medical device and the portable authentication device is successfully established, and
• the medical device is adapted to determine whether or not the portable authentication device is located at a position where acoustic communication between the medical device and the portable authentication device is possible, depending on whether or not it receives the predetermined acoustic signal.
