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.

Abstract: The present invention relates to a process for the estimation of treatment duration of peritoneal dialysis treatment: wherein the estimation of treatment duration is performed based on an ideal treatment duration, wherein the ideal treatment duration is increased by one or more delay values, wherein the delay values depend on one or more apparatus-specific and/or patient-specific and/or process-specific parameters.
