The lymph tissue at the junction of the top wall and the posterior wall is called proliferator or pharyngeal tonsil (adenoid), and the anterior part of the nasopharynx is connected with the posterior nostril and the posterior septum. The posterior wall is continuous with the posterior wall of the oropharynx, corresponding to the first and second cervical vertebrae, and is collectively called the pharyngeal posterior wall. A funnel-shaped opening is arranged at the position of about 1cm of the rear end of the inferior turbinate on the left side and the right side of the nasopharynx, and is a eustachian tube pharyngeal opening (pharyneal opening of tympanopharyneal tube), and the front edge, the upper edge and the rear edge of the opening are provided with lip bulges formed by the tail end of the eustachian tube cartilage, which are called eustachian tube bulge and are also called eustachian tube round pillow (torus tubalis). A deep fossa, known as the pharyngeal pouch (pharyngeal access), is located above the posterior aspect of the eustachian tube bulge and is the well-developed part of nasopharyngeal carcinoma, and the upper part of the deep fossa is only about 1cm away from the rupture hole of the skull base, so that malignant nasopharyngeal tumors can enter the cranium. The abundant lymphoid tissue around the pharyngeal orifice of the eustachian tube is called the eustachian tube tonsil (tubal tonsil). The nasopharynx has a large number of common diseases in clinic, and patients are generally required to be treated by oral administration, or operation, radiotherapy and chemotherapy, but a device capable of directly spraying the medicines for treatment to the nasopharynx by avoiding the nasal valve in the nasal cavity and the interference of the nasal turbinates is also required in clinic.
However, at present, only a device for spraying the medicine is arranged at the position of the nasal cavity in the nasal vestibule, the medicine spraying mouth is designed to only spray the medicine to the nasal vestibule of the nasal cavity, then the medicine is absorbed by the mucous membranes near the nasal vestibule and the nasal inner hole of the nasal cavity, and the medicine is distributed to all organs of the whole body through blood circulation; the effective bioavailability of the drug reaching the nasopharynx is extremely low and the need to locally enhance the bioavailability of the drug in the nasopharynx cannot be met. The nasopharynx part is arranged at the back of the nasal cavity from the skull base to the level of the free edge of the soft palate, and the nasal cavity of a human body has physiological structures of a turbinate and a nasal valve, so that the medicine cannot be directly delivered to the nasopharynx part by utilizing the existing nasal cavity medicine spraying device. At present, no device or method can meet the clinical requirement of local administration to the nasopharynx part.
