A modified laryngeal mask airway device (LMA-device) (20) is provided with means to improve ease of insertion, reliability of function and higher seal pressure (i.e., cuff pressure ratio). The LMA-device (20) includes an indented section (140) of the airway tube (47) to offer locating means and purchase for the inserting finger, and extended mask aperture bars (115, 117) to increase the effective ventilating area of the mask (20) and reduce the possibility of epiglottis displacement occasioned by mask insertion. The LMA-device (20) further includes a modification of the airway tube angle (137) of attachment to the mask (20), and provision of a posterior or back--cushion (77) covering the entire posterior surface of the mask (20).

L'invention concerne un dispositif (20) respiratoire à masque laryngé doté de moyens permettant d'améliorer la facilité d'insertion, la fiabilité d'emploi, et d'assurer une plus haute pression d'étanchéité (c'est-à-dire le taux de pression du ballonnet). Ledit dispositif (20) comprend une section indentée (140) du tube respiratoire (47) pour offrir des moyens de localisation et un point d'appui au doigt d'insertion, et des tiges (115, 117) d'ouverture du masque prolongées pour augmenter la surface de ventilation effective du masque (20) et réduire la possibilité d'un déplacement de l'épiglotte provoqué par l'insertion du masque. Ledit dispositif (20) comprend également une modification de l'angle de fixation (137) du tube respiratoire au masque (20), ainsi qu'un coussinet (77) postérieur ou arrière qui couvre toute la surface postérieure du masque (20).
