Medical apparatus with improved user interface
First Claim
1. 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, andcalculate 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.

Abstract
A medical apparatus comprises a control system allowing storage of a number of shaping profiles. Each shaping profile is stored as a plurality of pairs, including a shaping profile reference value and a time interval value. The reference value is represented as fraction, for instance a percentage, of the total weight loss the apparatus should achieve at the end of a treatment time. Each time interval value is represented either as fraction of the total treatment time or as a prefixed actual time interval. The control system calculates the actual weight loss rate versus time profile based on the desired total weight loss, on the desired total treatment time as well as on selected desired shaping profile.
