1. A medical measurement device having an impedance measurement unit having at least one measurement electrode pair comprising a first electrode and a second electrode and at least one feed electrode pair,
wherein the impedance measurement unit is for detecting an impedance measurement signal on a skin surface of a patient by way of the at least one measurement electrode pair, wherein a distance between the first and second electrodes of the at least one measurement electrode pair is within a range of from 1000 micrometers to 1 centimeter, wherein the at least one feed electrode pair comprises a first feed electrode and a second feed electrode for applying an alternating current of variable frequency to a body tissue of the patient, wherein the at least one measurement electrode pair and the at least one feed electrode pair are configured to simultaneously touch a first region of the skin surface, wherein the medical measurement device further comprises a program-controlled evaluation unit connected with the impedance measurement unit, wherein the program-controlled evaluation unit comprises a data processor programmed with software to determine changes in a local impedance measurement signal, and wherein the program-controlled evaluation unit is programmed to determine local resistance and local reactance from the local impedance measurement signal in that the program-controlled evaluation unit comprises an analog/digital converter configured to digitalize the local impedance measurement signal and to subject a digitalized local impedance measurement signal to a discrete Fourier transformation to determine at least one member selected from the group consisting of
a heart rate,a pulse amplitude,a local perfusion,a local body temperature, anda blood glucose levelfrom the changes in the local impedance measurement signal over time caused by an amount of blood changing within a pulse beat. |
