For reflectometric examinations and measurement of human or animal cavities, e.g. examination of air passages, eating passages etc., the device includes a flexible hose (1), which in the passage in question is introduced into the cavity in question, with the distal end of the hose placed past the zone of the passage to be examined. A transducer (3) converts an activation signal from a signal generator (2) to an excitation signal which is sent onwards to the interior of the hose. A response signal depending on the local deformations of the hose in the examined zone is picked up by a transducer (5) and subjected to analysis in relation to the excitation signal. An analysis circuit (4) and a computer (6) give an image on a screen indicating the results of the examination.
La présente invention concerne un dispositif d'examen et de mesure réflectométriques de cavités humaines ou animales, telles que notamment les voies respiratoires ou digestives. Ce dispositif comporte un tube flexible (1) à introduire par la voie concernée dans la cavité à examiner, l'extrémité distale du tube se situant au-delà de la zone à examiner. Un transducteur (3) convertit un signal d'activation envoyé par un générateur de signaux (2), en signal d'excitation qui est envoyé à l'intérieur du tube. Un signal de réponse proportionnel aux déformations locales du tube dans la zone examinée est récupéré par un transducteur (5) et soumis à analyse en fonction du signal d'excitation. Un circuit d'analyse (4) et un ordinateur (6) permettent de restituer à l'écran une image représentative des résultats de l'examen.
