A laryngeal mask airway device is provided that incorporates a video sensor, such as a CCD, CMOS or NMOS imaging chip, arranged to provide an image of the laryngeal inlet or other airway structures. The video sensor is electrically coupled to a reusable processing unit that receives the signals generated by the video sensor and generates a digital image of the interior of the patient's airway, thereby enabling the clinician to have immediate optical confirmation of the position of the mask aperture relative to the laryngeal inlet from the moment of insertion of the device. |
