Abstract: Methods for customization of a user interface of a microprocessor controlled medical apparatus for extracorporal blood treatment are disclosed, whereby the medical apparatus comprises a software component driving the user interface on a touch screen of the medical apparatus, and the software component has a technical support and maintenance mode and a treatment mode. At least one target window is displayed on the touch screen during therapy in the treatment mode, and such target window shows at least data regarding measured and/or set values of the therapy, whereby at least the appearance of one target window is modified by a customization procedure that is performed within the target window in the treatment mode. The invention further relates to a medical apparatus for extracorporal blood treatment that uses the method.

Abstract: Methods for setting mutually dependent parameters of a microprocessor controlled medical apparatus are disclosed. Mutually dependent parameters may be set by displaying mutually dependent parameter settings, displaying possible values for at least one parameter setting, whereby limits of the range of possible values is mutable and is automatically determined based on the current parameter settings, adjusting a parameter setting upon manual selection by an operator, automatically determining and displaying the value of at least one parameter setting depending on the parameter setting that is adjusted by the operator, whereby the determination of the dependent parameter setting is based on a stored relationship between parameter settings, implementing the set of adjusted parameter settings by actuating a batch setting acceptance operation, and operating the medical apparatus based on the set of adjusted parameter settings.
