Abstract: The present invention relates to the field of blood treatment machines such as hemodialysis machines. The object of this invention is to improve upon a generic blood treatment machine such that a certain individualization of the treatment station with little or no expenditure of materials is made possible in order to make the treatment environment more pleasant for the patient to be treated on the machine. The inventive blood treatment machine (10) therefore includes a control unit (16) that is configured so that image files transmitted and/or indexed via a data interface (15) can be displayed on the display screen (13) of the blood treatment machine during a blood treatment. The present invention also includes an external memory means (20) for connection to the data interface (15) and a combination consisting of the blood treatment machine (10) and the external memory means (20).
