Abstract

Ce réservoir d'anesthésique (1), utilisé en particulier pour le desflurane, voit sa sécurité de fonctionnement nettement améliorée grâce à des dispositifs de surveillance, se complétant les uns les autres, permettant de surveiller le niveau de remplissage. Le réservoir d'anesthésique (1) est équipé d'un tube indicateur de niveau (3) monté dans ou sur la paroi extérieure, d'une conduite de liaison (6) présente à l'intérieur, ainsi que d'un détecteur optique du niveau de remplissage (4), et l'axe optique (5) du détecteur du niveau de remplissage (4) se trouve à la même hauteur qu'un marquage (33) présent sur le tube indicateur de niveau (3).
