AI Technical Summary

Technical Problem

Existing nasal irrigation devices are limited in function, cannot heat the irrigation fluid, irritate the nasal cavity when used in cold environments, are inconvenient to collect and dispose of waste fluid, have unstable structures, are cumbersome to operate, have unstable pressure regulation, provide a poor user experience, and lack parameter monitoring.

Method used

A nasal irrigation device for allergic rhinitis was designed. It consists of a liquid-collecting cylinder connected to a mounting frame via a threaded connection, an electric heating element to regulate temperature, a booster pump to regulate pressure, a PLC controller to monitor and display, a horn-shaped liquid receiving plate to collect waste liquid, a protective tube to prevent leakage, a multi-directional spray head for directional rinsing, and a PLC to control the output mode of the booster pump, thereby achieving precise control of temperature and pressure.

Benefits of technology

It features convenient liquid heating and pressure regulation, a robust structural design, and efficient waste liquid collection, enhancing the user experience, reducing the risk of nasal irritation, and improving rinsing effectiveness and comfort.
