The invention relates to an artificial airway device (1) to facilitate lung ventilation of a patient, comprising an airway tube (2) and a mask (3) carried at one end of the airway tube, the mask (3) having a distal end (4) and a proximal end (5) and a peripheral formation (6) capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation (6) surrounding a hollow interior space or lumen (7) of the (mask (3) and the bore of the airway tube (2) opening into the lumen (7) of the mask, the airway tube including support means (44) such that the cross sectional area of the bore is substantially maintained upon application of pressure by the patient's teeth, while allowing local deformation of the tube at the point of tooth contact.患者の肺の通気を容易にするための人工気道装置（１）は、気道チューブ（２）と気道チューブの一端に取付けられたマスク（３）とを備え、マスク（３）は遠位端（４）と近位端（５）と喉頭口の周辺部の周りに封止を形成可能な周辺構成部（６）とを含み、周辺構成部（５）はマスク（３）の内部の中空空間または内腔（７）を囲み、気道チューブ（２）の穴はマスクの内腔（７）の中へ開口し、気道チューブは、歯の接触部でチューブの局所的変形を許容しながら、患者の歯によって圧力が加わる際に穴の断面領域が実質的に維持されるような支持手段（４４）を含む。
