摘要

Laryngeal mask tube coupled with the secondary entrance laminar flow of additional gas for breathing circuits, consisting of an air circuit (I) 5 for ventilation system, comprising a cannula (2) equipped with outlet nozzle (3) in its edge distaI, qua L receive, according to the project, a secondary tube (4) attached by one of its ends (4a),The supply system of the air + anesthetic and, at the end (4b) opposite free, forming a terminal (5) in sharp 10 curvature, said secondary tube (4) arranged in parallel, and through the terminal (5) of the free edge (4b) penetrating through the proximal end of the cannula (2).The cannula (2) is positioned with its proximal end coupled to the terminal (5) of the secondary tube (4) along the airways of the lung (P) of the patient (PA), and with the laminar flow toward the nozzle 15 in an exit (3) air circuit (I).The CO2 from the breathing process is, of course, swept by laminar flow in the interior of the fi cannula (2) and the volume of air + anesthetic penetrates directly to the airways of the patient (P). The circuit is improved pienituu00e0e most air u00e0e Ar + 20 to facilitate the ofereciu00e0o anaesthetic and respiratory movements by the patient (PA).
