Description

Technical Field

[0001] The utility model relates to the field of earwax cleaning, in particular to a disposable earwax washer. Background Art

[0002] The skin of the cartilaginous part of the external auditory canal contains cerumen glands, which secrete a sticky, yellowish substance called earwax, commonly known as earwax. When air-dried, earwax forms flakes; some forms resemble thick, greasy oil, often referred to as "greasy ear." Earwax protects the skin of the external auditory canal and helps retain foreign matter. Normally, earwax is expelled naturally through chewing and mouth opening. However, if earwax gradually clumps and blocks the external auditory canal, it's called cerumen blockage.

[0003] Cerumen irrigation is a common procedure in otolaryngology. Its primary purpose is to flush out cerumen, epidermal plugs, and foreign matter from the external auditory canal. Given the increasing emphasis on quality of life and the growing acceptance of aseptic practices, more and more patients are choosing to visit hospitals for cerumen removal. Clinically, irrigation often uses a 20ml syringe with a flexible tube. This can lead to the needle and tube becoming easily dislodged, making it difficult to control the direction of irrigation and resulting in poor irrigation effectiveness. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a disposable earwax flusher, which can effectively solve the problems of easy detachment of the needle and the hose, difficulty in controlling the flushing direction and poor flushing force.
