1. A device for generating measurement data relating to movements of the abdominal wall of a person, comprising:

  • at least one first pair of sensor units which are configured for detachable fixing to the skin on an abdominal area of a person, spaced apart by a first distance (L1), a measuring device connected to the first pair of sensor units and configured for detecting signals of the sensor units which can be electronically evaluated, and for generating a first distance signal corresponding to the first distance (L1) and changes thereto;

    an evaluation unit connected to an output of the measuring device, where the evaluation unit evaluates pulsed and/or waveform changes in the first distance signal by;

    (1) identifying non-periodic or periodic changes lasting at least 10 seconds;

    (2) distinguishing the changes lasting at least 10 seconds from periodic changes caused by human breathing by identifying whether the signal has a form that is symmetrical with respect to a signal/time diagram of the first distance signal, and (3) outputting an output signal which can be displayed or evaluated further.
