Description

Technical Field

[0001] The present invention belongs to the technical field of ear and nose washing devices, and in particular relates to an ear and nose washing device. Background Art

[0002] Otolaryngology is an important branch of medicine, involving many aspects of human hearing, breathing, smell, language, etc. Common diseases in otolaryngology include otitis, sinusitis, pharyngitis, tonsillitis, etc. These diseases not only affect the quality of life of patients, but also may lead to serious consequences such as hearing loss, breathing difficulties, olfactory disorders, and pronunciation disorders. Therefore, it is very necessary to treat otolaryngology diseases in a timely and effective manner.

[0003] During the treatment of ENT, it is often necessary to clean and rinse the ears, nose and throat to remove foreign matter, secretions, germs, etc. in these parts, reduce inflammation and symptoms, and promote healing. At present, there are some irrigating devices for ENT on the market, such as ear irrigators, nasal irrigators, throat irrigators, etc. These irrigating devices usually achieve the purpose of irrigating by injecting or spraying warm water or drug solutions into the ENT area.

[0004] However, existing flushing devices are usually unable to effectively control the pressure, temperature and flow of water, resulting in unsatisfactory flushing effects and even possible damage or discomfort to the ENT area. At the same time, most flushing is done by manual squeezing, which is difficult to operate and has unstable water pressure. Excessive water pressure may irritate or damage sensitive tissues of the ENT area, causing bleeding or infection; if the water flow is too large or too small, it may result in incomplete flushing or waste of cleaning solution. Utility Model Content
