The invention relates to the technical field of artificial throats, and provides a transnasal pneumatic type artificial
throat which comprises a sound
guide tube assembly, the sound
guide tube assembly comprises an intranasal sound
guide tube and an extranasal sound guide tube, the intranasal sound guide tube is placed through a
nasal cavity, the placing end of the intranasal sound guide tube extends to the upper section of a
pharyngeal cavity or an
esophagus, and the extending end of the intranasal sound guide tube is fixed outside the
nasal cavity; the sound guide tube is connected with one end of the out-of-
nose sound guide tube; the trachea cannula
assembly is connected with the other end of the extranasal sound guide tube; and the vibration assembly is arranged in the intranasal sound guide tube or the extranasal sound guide tube and is used for converting the air flow of the trachea into
sound wave vibration. Through the
collaborative design of the
nasal cavity sound guide path, the vibration
film structure and
reverse airflow sound wave conduction, the intranasal sound guide tube is designed to directly reach the
pharyngeal cavity from the
nasal vestibule to the lower nasal meatus to the nasopharynx, and the
sound wave channel independent of the
oral cavity is designed, so that the problems that the
oral cavity or the trachea channel needs to be occupied in the placement mode of the existing
sound production device, and the operation is inconvenient are solved. And the
vowel definition is reduced due to the interference of the tongue, lip and tooth
vowel motion.
