Abstract

Es wird ein Gasanalysator für die medizinische Diagnostik beschrieben, der die bei einer Erkrankung aus festen, flüssigen oder gasförmigen Körperausscheidungen oder aus Kulturen von pathogenen Erregern oder Parasiten freigesetzten charakteristischen, gasförmigen Substanzen oder mit der Erkrankung korrelierende Veränderungen in der Gaszusammensetzung in Signalmuster umwandelt und mit den vorher in einer Datenbank abgespeicherten charakteristischen Signalmustern von bei bekannten Erkrankungen entstehenden gasförmigen Substanzen vergleicht. Der Gasanalysator zeichnet sich dadurch aus, dass er ein aus einem oder mehreren Gassensoren bestehendes Sensorarray aufweist, in dem mindestens einer der Sensoren ein spezifischer Detektor für ein zur Einregelung einer konstanten Konzentration in einer Sensorkammer verwendetes, angesaugtes Gas ist, einen weiteren Gassensor oder ein weiteres, aus mehreren Sensoren bestehendes Sensorarray aufweist, in dem mindestens einer der Sensoren ein spezifischer oder unspezifischer Detektor für eine mit einer Erkrankung verbundene, charakteristische, gasförmige Substanz ist und eine Verdünnungseinheit enthält, mit der eine bestimmte Konzentration der im Gasvolumen enthaltenen Bestandteile eingestellt werden kann.
