Abstract
The invention relates to an apparatus for measuring cross sections in a patient's right and left nose cavity in the cavity behind the nose separation (epipharyn), and in the throat (oropharynx), and for detecting the opening of the Eustachian tube. The apparatus comprises an electro-acoustic sound emitter, a first transmission tube leading from the emitter to a first connecting piece, connecting means for connecting the first connecting piece to a patient's one nostril, a proximal microphone located adjacent the emitter and/or a first microphone built into the first connecting piece, and a computer for generating electrical signals for the emitter and for sampling and analyzing electrical signals from the microphone or microphones. According to the invention the apparatus further comprises a preferably releasable second acoustic transmission tube leading from the emitter in an opposite direction of the first acoustic transmission tube, hereby constituting an elongation of this pass the emitter. The invention further relates to a method for measuring the above-mentioned cross sections.
