Patent attributes
A laryngeal airway device, having an airway tube which has an internal passage in the airway tube wall for receiving a cuff inflation line, and a dome having an inlet and an outlet, where the dome is connected at its inlet with the distal end of the airway tube. The device also includes an annular spoon-shaped inflatable cuff connected with the periphery of the outlet of the dome; a cuff inflation line configured to be in fluid communication with the internal space of the cuff; and a multi-lobed aperture formed in the dome. The aperture is configured to be in fluid communication with the proximal end of the airway tube. The dome has protrusions forming the multi-lobed aperture, such that a flap is configured to prevent the obstruction of the aperture by a patient's epiglottis when the device is inserted into the patient.
