<p>A device (10) for maintaining an airway in a patient comprises a mask (12), the mask having a resilient conformable peripheral portion (20, 22) shaped such that the mask (12) forms a seal with the larynx when the mask is positioned in the laryngo pharynx to thereby prevent ingress of extraneous fluids into the larynx, the peripheral portion (20, 22) of the mask defining at least one cavity (32, 34) for providing fluid communication to the oesophagus when the mask is inserted into the laryngo pharynx, and an airway tube (14) connected to or formed with the mask for passing gas to the larynx when the mask is properly inserted into the laryngo pharynx. The airway tube (14) preferably is curved as it leaves the mask.</p> |
