There is disclosed an oropharyngeal airway (10) which comprises a curved portion (11) which provides a pharyngeal end (12) of the airway, and a straight portion (13) which communicates with the curved portion (11) and which provides a buccal end (14) of the airway. The straight portion (13) is formed integrally with the curved portion (11) and is made from plastics and/or elastomeric material. At least one circular cross- section passage extends substantially throughout the length of the straight portion (13), and the straight portion (13) has a substantial wall thickness surrounding the passage to provide rigidity sufficient to resist collapse of the straight portion under biting-action of a patient. Conveniently, one of the passages serves as a catheter guide, while the remaining passage serves to convey air to the curved portion. <IMAGE> |
