Graphical operator machine interface and method for information entry and selection in a dialysis machine

A method of programming a dialysis machine using a graphical operator machine interface to establish machine operating and dialysis treatment parameters employed by the dialysis machine in a dialysis treatment, comprising the steps of:

• using a graphical screen to access, select, display and enter information;
• displaying in a first screen display on the graphical screen a first predetermined group of a plurality of predetermined machine operating and dialysis treatment parameters used by the dialysis machine in a dialysis treatment;
• and
• entering parameter selection information on the graphical screen at the first screen display to select a second selected group of the parameters from the first group, the second selected group formed by a lesser number of the parameters than are present in the first group;
• and thereafter
• displaying the second selected group of parameters on the graphical screen in a second screen display, the second screen display being different from the first screen display.

A dialysis machine having a graphical operator machine interface ("OMI") by which to establish machine operating and dialysis treatment parameters employed by the dialysis machine in a dialysis treatment, wherein the graphical OMI comprises:

• a graphical screen by which to access, select, display and enter information;
• a screen display circuit connected to the graphical screen to display on the graphical screen a plurality of screen displays, the plurality of screen displays include a first screen display of a first predetermined group of a plurality of predetermined machine operating and dialysis treatment parameters;
• and
• a touch-responsive input circuit connected to the graphical screen and to the screen display circuit, each screen display on the graphical screen being correlated with the input circuit to allow touch-responsive entering of information correlated to the screen display;
• the input circuit responding to entered information from the first display screen to identify a plurality of parameters from the first predetermined group and to assemble the identified parameters from the first predetermined group into a second selected group formed of a lesser number of the parameters than are present in the first predetermined group;
• and
• the screen display circuit responding to the identification of the second selected group of parameters to display the second selected group of parameters on the graphical screen in a second screen display, the second screen display being different from the first screen display.
