Abstract: A medical device, such as a hemodialysis or peritoneal dialysis machine, has at least one housing, electrical and/or electronic components arranged inside the housing, and a user interface. The medical device has a first receiving device accessible outside of the housing and a first communications interface for receiving a proximal end of a medium carrying communication signals. A distal end of the medium is provided for connection to a second communications interface associated with a communications network. Components of the medical device are communicatively connected to the first communications interface. A communication link between the distal end of the medium and the components of the medical device has at least two segments. At least one of the segments transmits communication signals in an electrically non-conductive manner and has electrical isolation between the input and output and/or between the output and input of the segment with a predetermined first dielectric strength.
