[A method for worst-case study of coupling between medical equipment].
The increasing use of electronic devices in operating theatres and intensive-care units leads to possible interactions of such devices and consequently to serious immunity problems. This paper presents a numerical near field worst-case-study of the coupling between coagulators and ECG devices under consideration of the human body. For this purpose a special body model has been developed which meets the geometrical dimensions given in DIN 33402 part 2. The model's electrical properties correspond to a weighted average of those of different tissues of the human body. Different parameters (coagulation frequency, positions of electrodes, etc.) are considered.
