Dialysis system with measuring devices for the detection of the blood pressure, as well as a method for determining the blood pressure, as well as a storage medium for use in a dialysis system

摘要

The present invention relates to a dialysis system with a the dialysis machine and associated measuring unit for detection of the blood pressure, with a the dialysis machine and associated measuring device for recording a pulse-wave running time, as well as with an evaluation unit, in which the evaluation unit is configured such that from this a pulse-wave running time the blood pressure representierendes signal can be derived, wherein the parameters of the relationship between the pulse-wave running time and the blood pressure of a plurality of measured values of the measuring unit for detection of the blood pressure and simultaneously measured values of the measuring device for detecting the pulse-wave running time can be determined, wherein at least two of these measured-value pairs at times, can be ascertained in the case of which the absolute and / or the relative deviation of the pulse-wave running time and / or of the blood pressure is above a threshold value. The invention also relates to a process for the determination of the parameters of the relationship between a pulse waves running time signal and a blood pressure measuring signal, wherein below from the pulse-wave running time a signal representing the blood pressure is derived, wherein the parameters of the relationship between the pulse-wave running time and the blood pressure of measured values of the blood pressure measuring signal and instantaneous measured values of the pulse-wave running time are determined, wherein at least two of these measuring value pairs at times be determined, in which the absolute and / or the relative deviation of the pulse-wave running time and / or of the blood pressure ..
