Full nasal cavity air pressure detecting device and application method thereof

Abstract

The invention relates to the technical field of detection. A full nasal cavity air pressure detecting device comprises a bracket, a nasal cavity model simulating a human nasal cavity, a pressure detecting system and a breathing simulation system. The nasal cavity model is provided with a vestibule simulation air port and a nasopharyngeal simulation air port, and at least two test holes are openedin the nasal cavity model. All test holes are connected with a test air pipe respectively, and each test air pipe is equipped with a pressure sensor. The breathing simulation system includes an exhalation unit and an inhalation unit. The inhalation unit includes a vacuum pump, and the vacuum pump is connected with the nasopharyngeal simulation air port through an air suction channel provided withan intake valve. The exhalation unit includes an air compressor, the air compressor and the nasopharyngeal simulation air port are connected through an air passage, and the air passage is provided with an exhalation valve. The device simulates the breathing of the human body by alternately controlling the air bleeding and suction of the nasopharyngeal simulation air port, and simulates the pressure of different parts of the human body during breathing through the pressure sensors.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a nasal air pressure detection device and an application method thereof. Background technique [0002] Solving abnormal nasal airflow is one of the main purposes of nasal septum and nasal cavity surgery, so accurate assessment of nasal airflow is the key to improving the level of diagnosis and treatment. At present, the evaluation of nasal airflow is mainly based on the detection of nasal resistance, which can only reflect the overall resistance (pressure change) of the nasal cavity. Due to the complex and changeable anatomical structure of the nasal cavity, it is impossible to detect and analyze the air pressure changes in various parts of the nasal cavity, and it is impossible to accurately evaluate the nasal cavity. Abnormal internal airflow. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a whole nasal a...
