Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, in particular to an adjustable lacrimal duct flushing auxiliary device. Background Art

[0002] Tear duct irrigation is mainly an operation performed on patients with narrow lacrimal puncta or blocked tear ducts. This is because excessive secretions in the tear ducts may block the tear ducts, so this can avoid blockage. If the patient has chronic dacryocystitis, local infection can also be avoided, but local irrigation is difficult to be completely cured and requires subsequent surgical treatment. Tear duct irrigation is an operation technique that injects liquid into the tear duct to clear blockages in different parts of it. It can be used as a diagnostic technique as well as a treatment method. Patients need to do tear duct irrigation during ophthalmic treatment, and normal saline will flow out during irrigation.

[0003] At present, the adjustable tear duct flushing aid on the market has the following disadvantages: when in use, it is not convenient to adjust the aid according to the size of the user's head, and the adjustability of the aid needs to be improved. At the same time, when using the aid, it is not convenient to disassemble and clean it, and frequent use will cause cross infection.

[0004] For example, CN213251141U discloses a head fixing device for assisting children's tear duct flushing, which includes a C-shaped stopper, a chin stopper and a mandibular angle stopper for supporting the tear duct to flush the neck of the child, the C-shaped stopper is provided with a neck opening for the child's neck to enter, the chin stopper is two and respectively connected to the two free ends of the C-shaped stopper, the mandibular angle stopper is two and respectively connected to the upper wall of the C-shaped stopper, and the two mandibular angle stoppers are respectively close to the two free ends and symmetrically arranged with the neck opening as the center. However, the fixing device cannot be adjusted in size to suit most head circumferences, and is not detachable, which is prone to cross contamination. Utility Model Content
