Patent ID: 7988850

Claim:
A blood treatment apparatus comprising: at least a user interface for enabling setting of at least one time-varying parameter pertinent to operation of said apparatus or pertinent to a process to be performed by said apparatus, the time-varying parameter being defined by a plurality of different parameter values that the at least one time-varying parameter takes during operation of the apparatus; and a control system programmed to control operation of said blood treatment apparatus, the control system being connected to the user interface and being responsive to actions by a user on said user interface, said control system being programmed to: store a plurality of reference values defining a shaping profile, store the value of at least a discriminating factor which relates to the time-varying parameter, and calculate each of the parameter values as a function of a corresponding reference value of the shaping profile and of the value of said discriminating factor, wherein each of said reference values is represented as a fraction of the discriminating factor value, and wherein the calculation of each parameter value comprises the step of multiplying each reference value by the value of said discriminating factor.
