Abstract

A peritoneal dialysis machine including a membrane pump and a touch screen display that includes a mode-indicating portion and an operation-descriptive portion, the mode-indicating portion having a plurality of touch sensitive indicia each indicating one of a plurality of modes in which the machine can operate, the display being used to keep a patient continually informed of which one mode of at least three operating modes the machine is operating in, as the operation-descriptive portion changes to display details of a specific operation being carried out within the one mode, the indicia for each of the three operating modes always being visible to the patient while the machine is operating, the operating mode being selected by the patient touching one of the indicia on the screen.

Claims26

Dependent claims

A peritoneal dialysis method for operating a peritoneal dialysis system, the system including

a stepper motor housed by an enclosure,
a pump head in operable communication with the stepper motor,
a disposable unit including at least one flexible membrane attached to a rigid piece, the enclosure configured to receive the disposable unit such that the stepper motor can move the pump head towards and away from the flexible membrane, and
a graphical user interface including a display device, the method comprising:
displaying a plurality of peritoneal dialysis (“PD”) screens on the display device, a first area of the display device dedicated to a plurality of mode selection icons, each mode selection icon dedicated to a single mode, the area and the mode selection icons displayed on each of the peritoneal dialysis screens;
temporarily displaying on a second area of the display device, exclusively as a result of a user selection of one of the mode selection icons, at least one of a graphic and text specific to a selected corresponding mode, the modes including a therapy mode, a parameter adjustment mode and a log mode;
and
causing, upon selection of one of the modes, the display device to operate in the selected mode, the therapy mode including a graphic pictorially discerning between a PD fill cycle and a PD drain cycle and pictorially indicating how far the fill or drain cycle has proceeded.

A method for operating a peritoneal dialysis machine, the machine including a touch screen display that includes a mode-indicating portion and an operation-descriptive portion, the mode-indicating portion having a plurality of touch sensitive icons each indicating one of a plurality of modes in which the machine can operate, the display being used to keep a patient continually informed of which one mode of at least three operating modes the machine is operating in, as the operation-descriptive portion changes to display details of a specific operation being carried out within the one mode, the icon for each of the three operating modes always being visible to the patient while the machine is operating, the operating mode being selected by the patient touching one of the icons on the screen, the method including:

(i) touching one of the icons to select a current operating mode in which the machine is operating, the icon for the selected mode being highlighted in response to that mode being selected;
(ii) displaying, in the operation-descriptive portion of the display, and exclusively as a result of a touching of one of the icons, information concerning the operation of the machine within the selected operating mode without changing either the display of the icon for each of the three operating modes or changing the highlighting of the icon for the selected mode;
and
(iii) selecting a different icon to change the mode of operation of the machine, which operates as an exclusive way to (a) cause a different icon to be highlighted and at the same time (b) cause the previously selected icon for the prior mode of operation to be unhighlighted.
