The device includes an airway tube, a mask attached to the airway tube, a peripheral inflatable cuff, and an outlet for gas. The mask is attached to the airway tube for gaseous communication between the tube and an outlet. The device further includes an oesophageal drain that includes a conduit that extends from an inlet at the distal end of the mask to an outlet disposed outside the patient when the device is in place. The conduit includes a mask section and airway tube section, wherein the mask section is formed integrally in the material of the body of the mask.
