Abstract

Procédé et dispositif permettant de déterminer avec précision, pendant et après la phase d'insertion, la position en longueur normale des cathéters (y compris des dispositifs d'accès implantés (64)), des tubes (30) et des guides de pose métalliques (22) sous le tissu biologique. Ledit dispositif est constitué d'un ensemble émetteur/détecteur (2) comprenant un émetteur haute fréquence (H.F.) à courant alternatif (C.A.) doté d'une antenne (14), et d'un émetteur de signaux radioélectriques ayant l'apparence d'une antenne de réception en fil fin continue ou segmentée (28, 32, 74) laquelle est positionnée sur toute la longeur du cathéter, du guide métallique et des ensembles de dispositifs d'accès implantés (22, 30, 64). Le dispositif de guide métallique comprend aussi une antenne d'extrémité. Ces antennes se raccordent au moyen d'une pince amovible (18) à un circuit de détection H.F. à large bande se trouvant à l'intérieur de l'ensemble émetteur/détecteur (2). Le circuit de transmission/détection H.F. fournit une sortie en tension, laquelle est fonction de la proximité spatiale relative de l'antenne émettrice. Cette proximité est signalée visuellement à l'utilisateur au moyen d'une matrice de diodes luminescentes linéaires séquentielles (8) dont la sensibilité est ajustée par un bouton de réglage de gain (10).
