Abstract:
1. A mobile diagnosis device comprising: an ECG unit to record an ECG signal, with the ECG unit being connected to two or more ECG electrodes to measure electrical signals from a patient's body; a pulsoximetry unit for simultaneous recording of a volume pulse signal, the pulsoximetry unit comprising at least one light source and at least one light sensor for optical measurement of blood perfusion in the vascular system of a patient's body tissue; a program-controlled evaluation unit to evaluate the ECG signal and the volume pulse signal; and a casing that accommodates the ECG unit, the pulsoximetry unit and the evaluation unit, wherein the ECG electrodes and the light source and the light sensor of the pulsoximetry unit are arranged on an exterior surface of the casing, the ECG electrodes being connected to the device without a cable connection, wherein the light source and the light sensor of the pulsoximetry unit are integrated in a first ECG electrode of the ECG electrodes in such a manner that a patient can touch the first ECG electrode with one hand and a second ECG electrode with the other hand, while touching the light source and the light sensor at the same time; wherein said evaluation unit is appropriately equipped to allow for automatic recognition of R peaks in the ECG signal, automatic recognition of extreme levels in the volume pulse signal, and for determination of the time difference between an R peak in the ECG signal and a successive extreme value in the volume pulse signal.
