Description

Technical Field

[0001] The utility model relates to the technical field of nasal medical instruments, in particular to a nasal irrigation device which is convenient for controlling the irrigation dosage. Background Art

[0002] A nasal irrigator is a medical device for cleaning the nasal cavity. The existing nasal irrigator is composed of an elastic bottle body and an irrigation tube. When in use, the irrigation tube is inserted into the nasal cavity, and then the elastic bottle body is squeezed to force the cleaning fluid into the nasal cavity, flowing through the nasal vestibule, sinuses, nasal passages, bypassing the nasopharynx, or being discharged from one nostril, or from the mouth. Through the above paths, with the help of the impact force of the cleaning fluid flow, the pathogenic bacteria and dirt that have accumulated in the nasal cavity are discharged, thereby restoring the nasal cavity to a normal physiological environment, restoring the nasal cavity's self-detoxification function, and achieving the purpose of protecting the nasal cavity.

[0003] With existing nasal irrigation devices, after the doctor presses the elastic bottle body, the cleaning liquid flows out. Often, the elastic bottle body is released before the irrigation head is taken out of the nasal cavity, and the bottle body rebounds, which easily attracts residual liquid inside the nasal cavity, causing it to flow back into the elastic bottle body, contaminating the elastic bottle body and making it inconvenient to use. Therefore, a nasal irrigation device with convenient control of the irrigation dosage is proposed. Utility Model Content
