Abstract
A device for impedance measurements on body segments. Outputs of a current source are connected to inputs of current changeover switches. Each current changeover switch has outputs that are interconnectable with the input of the respective current changeover switch. The outputs of the current changeover switches are connected to electric feed lines of current electrodes. Measuring electrodes detect voltage signals, which are used with the current supplied by the current source for the impedance measurements of the body segments. Switching devices are incorporated into the electric feed lines near the current electrodes. By switching the current changeover switches and switching devices, the device respectively connects only two current electrodes to the current source and disconnects all other current electrodes from the electric feed line by switching the switching device and the electric feed line from the current source by switching the current changeover switches.
