An airway device 10 is provided for sealing a patient's pharynx P, the device comprising a hollow stem 40 for passing through mouth M; an elongate flexible chamber for sealing against the pharynx; and an attachment formation 42 of 22mm diameter, for attaching to external ventilation apparatus. The sealing component is made of resilient material with a leading end 14 and trailing end 16, and top 18 and bottom 19 elongate surfaces. The top surface has raised ridge 20 (see figure 5) to seal at the base B of the tongue T. An opening 26 is defined in the top surface and serves to link the chamber and hollow tube with the laryngeal inlet L. The bottom surface is shaped to seal the back of the throat, and has a gutter 28 (see figure 3) from the leading edge along the length of the bottom surface 19 to provide access to the oesophagus O. Lateral gutters 44 along the stem are for directing gastric instruments into the gutter 28 in the bottom surface. |
