[0002] Pharyngeal cancer is one of the most common malignant tumors in my country. Radiotherapy is its main treatment method. Patients with nasal cancer have more nasal secretions. Especially during radiotherapy, the patient's nasal cavity needs to be kept clean, so patients need to perform nasopharyngeal irrigation every day to ensure the efficacy. However, radiotherapy can easily cause damage to the nasal mucosa and lose its self-cleaning function. Therefore, nasopharyngeal and nasal irrigation is required during and after radiotherapy.

[0003] However, there are some problems in the prior art: 1) During the preparation process, the staff needs to prepare warm water, put the medicine into the warm water and stir it to dissolve. The warm water will cool down during use, irritating the nasal cavity and causing discomfort to the patient; 2) Traditional nasopharyngeal irrigation often causes patients to choke and cough during irrigation due to the fast and slow irrigation flow rate, which brings pain to the patients; 3) The current irrigator lacks a stirring device. When the medicine solution is added to the inside of the irrigator, it cannot be fully mixed with water, which easily affects the concentration of the medicine solution in the cleaning solution.
