Abstract

L'invention concerne un dispositif pour la fixation de cathéter dans des procédés d'anesthésie épidurale et d'anesthésie mixte épidurale-sous-durale. Le dispositif comprend : un corps principal avec une extrémité proximale et une extrémité distale ; une base qui colle à la peau du patient ; la base présente une paroi intérieure pour maintenir et contenir le cathéter. Le dispositif comprend un membre mobile relié pivotant à la base et présente une position de fixation et une de libération ; dans la position de fixation, le membre mobile est introduit dans la base, définissant une trajectoire pour maintenir le cathéter qui demeure emprisonné à l'intérieur du corps principal. Le dispositif présente un revêtement transparent qui protège et permet de voir le point de ponction ; ledit revêtement loge un matériau absorbant. Dans la position de libération, le membre mobile tourne pour se retirer de l'intérieur de la base en libérant le cathéter, permettant son extraction à l'aide d'une paire de nervures latérales, le dispositif présente une bande qui maintient le cathéter sur le dos du patient.
