<p>A device (10) for the non-invasive determination of arterial blood pressure of a human or animal body, comprising at least a bioimpedance measuring device (20) having a plurality of electrode pairs (21, 22, 23) for capturing the admittance signals (Y(t)) caused by an impressed alternating current on at least one first section of the body, wherein the captured admittance signals (Y(t)) correspond to a composite signal made of signal components of a pulse admittance (YP(t)), a respiration admittance (YB(t)) as well as a base admittance (Y0(t)), as well as at least one device for the non-invasive measurement of the blood pressure (30), wherein a processor (40) of the device (10), which separates from the admittance measurement signals (Y(t)), which are received by the bioimpedance measuring device (20) from several electrode pairs (21, 22, 23) arranged at a distance from each other on at least one first section of the body, wherein the measurements are carried out multiple times, each time using electrode pairs arranged at different sites of the body and/or at respectively different measuring frequencies, at least the signal components of the pulse admittance (YP(t)) and which determines the arterial blood pressure (PC(t)) from pressure signals (PP(t)) of a second section of the body, which is preferably disposed at a distance from the first section, which signals are received from the blood pressure measuring device for determining a scaling factor (k).</p> |
