DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0034] FIG. 1 illustrates a simplified representation of an apparatus for extracorporeal blood treatment 1 comprising a display device 2 in the present case having an external convexly curved display 3 and a person locating/identifying device 4. The display device 2 is preferably disposed in the upper area of the apparatus for extracorporeal blood treatment 1 (dialysis machine) so that it is within the viewing range of the user. The surface of the curved display 3 on the display device 2 is convexly curved and is turned away from the center of curvature so that it faces the user in the perimeter (preferably 360) of the apparatus for extracorporeal blood treatment 1 from all positions in the room, where appropriate. In the preferably upper area of the display device 2 the person locating/identifying device 4 is provided the sensor system of which covers the (complete) perimeter of the apparatus for extracorporeal blood treatment 1. The position of a person in the perimeter of the apparatus for extracorporeal blood treatment 1 is detected by the person locating/identifying device 4 and the detection signals of a controller/control unit/computer are preferably supplied to the apparatus for extracorporeal blood treatment 1. Since apparatuses for extracorporeal blood treatment 1 already belong to the state of the art and, as is known, they are always equipped with a control unit for controlling/regulating the functions internal to the apparatus, a more detailed description of such apparatus as well as of the control thereof can be dispensed with here; instead, the relevant state of the art, for example to the applicant of this application, can be referred to. The controller controls the display device 2 in such way that the information to be displayed can always be displayed in the direction of the user via the curved display thereof.
[0035] FIG. 2 illustrates a schematic representation of the ranges of interaction around the apparatus for extracorporeal blood treatment 1. The range of manual interaction 5 (average arm length) is the range indicated by the broken line around the apparatus for extracorporeal blood treatment 1 in which the user can establish direct contact with the apparatus for extracorporeal blood treatment 1 so as to manually operate e.g. actuating elements such as buttons and switches on the machine or the display device 2 or a touchscreen on the display device 2. The range of sensory interaction 6 indicated by a dash-dot line extends from the apparatus for extracorporeal blood treatment 1 beyond the range of manual interaction. Within the range of sensory interaction 6 the user is identified by the person identifying device 4 (not shown in FIG. 2) and the information displayed via the display device 2 is displayed in the direction of the user. Within the range of sensory interaction 6 e.g. gestures and/or the user identity of the user can be detected by the person locating/identifying device 4 so that the user can operate the apparatus for extracorporeal blood treatment 1 and/or display device 2 within the range of sensory interaction 6 contactless in a manner preferably selected/individually reduced to the user.
[0036] FIG. 3 illustrates a simplified top view onto a display device 2 including a polyhedral display 7 and plural display subareas 8 each having a viewing angle . The polyhedral shape is realized by planar adjacent display subareas 8 facing away from the center of the polyhedron and being orientated to different directions of the room. The viewing angle is chosen so that from each position within the perimeter around the apparatus for extracorporeal blood treatment 1 at least one display subarea 8 can be seen by the user. For reasons of simplification, the viewing angle was indicated at one display subarea 8 only.
[0037] FIG. 4 illustrates a schematic representation of the apparatus for extracorporeal blood treatment comprising machine components according to aspects of the invention. The apparatus for extracorporeal blood treatment 1 is equipped with a control unit 9 being connected to the display device 2 and the person locating/identifying device 4. The person locating/identifying device 4 is preferably equipped with a face recognition device 10. Signals that are detected/generated by the sensor system of the person locating/identifying device 4, for example the position of a person in the environment of the apparatus for extracorporeal blood treatment 1, the gestures and/or user identity thereof, where appropriate, and signals of the related face recognition device 10, where appropriate, are forwarded to the control unit 9. In response to the signals of the person locating/identifying device 4, the control unit 9 controls the display of the information on the display device 2, for example in response to the current position of the person detected by the person locating/identifying device 4 in the environment of the apparatus for extracorporeal blood treatment 1 the display direction of the information to be displayed on the display of the display device 2 is controlled. Equally, signals are forwarded from the apparatus for extracorporeal blood treatment 1 to the control unit 9 which, in response to the transmitted information from the apparatus for extracorporeal blood treatment 1, controls the information to be displayed by the display device 2. Also, the user-dependent authorizations for operating the apparatus for extracorporeal blood treatment 1 and the display device 2 are controlled by the control unit 9. For this purpose, the user identity is detected by the user identifying device 4, for example by reading out a person-related chip, or by face recognition by the face recognition device 10 and is forwarded to the control unit 9 which, in response to the pertinent user profile stored on the control unit 9, admits or blocks the operating inputs of the user.
