Abstract
(EN) An endo-tracheal catheter (1) for use in an anesthetic procedure comprises a catheter tube (10) to be inserted into the trachea (40) of a patient (4), the catheter tube (10) having a tubular wall (101) defining an inner lumen (102) for guiding a gaseous flow, and a connection piece (11) which defines a chamber (110) being in fluid connection with the catheter tube (10) and comprising a port (110) for connecting a detection device (2) to the endo-tracheal catheter (1) for detecting at least one substance in the gaseous flow flowing through the catheter tube (10). Herein, an insert tube (13) is received in the inner lumen (102) of the catheter tube (10) for guiding the gaseous flow through the catheter tube (10) and/or a coating (103) covers the tubular wall (101) at a side facing the inner lumen (102) for guiding the gaseous flow through the catheter tube (10). In this way, an endo-tracheal catheter is provided which allows for an accurate measurement of a substance concentration in a gaseous flow, in particular in the context of an anesthesia procedure.
(FR) La présente invention concerne un cathéter endo-trachéal (1) destiné à être utilisé dans une procédure anesthésique qui comprend un tube de cathéter (10) destiné à être inséré dans la trachée (40) d'un patient (4), le tube de cathéter (10) ayant une paroi tubulaire (101) définissant une lumière interne (102) pour guider un flux gazeux, et une pièce de connexion (11) qui définit une chambre (110) en communication fluidique avec le tube de cathéter (10) et comprenant un orifice (110) pour relier un dispositif de détection (2) au cathéter endo-trachéal (1) afin de détecter au moins une substance dans le flux gazeux s'écoulant à travers le tube de cathéter (10). Dans la présente invention, un tube d'insertion (13) est reçu dans la lumière interne (102) du tube de cathéter (10) pour guider l'écoulement gazeux à travers le tube de cathéter (10) et/ou un revêtement (103) recouvre la paroi tubulaire (101) sur un côté faisant face à la lumière interne (102) pour guider l'écoulement gazeux à travers le tube de cathéter (10). De cette manière, l'invention concerne un cathéter endo-trachéal qui permet une mesure précise d'une concentration de substance dans un flux gazeux, en particulier dans le contexte d'une procédure d'anesthésie.
