Description

Contrast agent injection device for dacryocystography

The present invention provides a contrast agent injection device for performing lacrimal angiography, in which a contrast agent is injected into the nasal tear duct of the lacrimal sac to find the problem part (tear canal, lacrimal pouch, nasal duct, etc.) when the tear length is blocked or narrow About.

The tears produced in the eye evenly cover the cornea, so it prevents visible objects from appearing crushed, and functions to wash away impurities and foreign substances, supplies nutrients to the cornea, kills germs, and is discharged through the nose.

However, there is a symptom that tears cannot be discharged to the nose and flows outside the eyes, which can be broadly divided into a case where the secretion of tears becomes excessive, and a discharge disorder that is a problem due to clogged tears.

Excessive tear secretion is usually caused by abnormal eyelids, irritation of eyelashes, foreign objects, conjunctivitis due to inflammation, keratitis, dry eye syndrome, functional and anatomical abnormalities leading to tear discharge, etc. In the case of functional problems due to hearing, the conjunctiva is sagging, interfering with the flow of tears, or being well guided by muscle paralysis around the eyes such as facial paralysis.

Excessive tear secretion can occur in cases of reflexive tears even when the eyes are dry, and can occur when there is a lot of irritation due to various conjunctivitis or corneal diseases including allergies, windy times or the use of lenses. Disorders can occur when the path through which tears are discharged into the nose becomes functionally problematic or blocked due to various causes.

If tears continue to overflow due to clogged tears, it can interfere with daily life and cause various inflammatory diseases such as conjunctivitis and weakening of vision.

Patients with a lot of tears like this (aka: Epiphora) determine whether the nasolacrimal duct is blocked or not by putting a colored liquid into the tear duct to determine whether it is blocked, or by injecting a contrast agent and then an X-ray. A fistula angiography test is required to confirm the blockage by a line.

Although the diagnosis of symptoms of eospatic patients is a preferred examination by medical institutions as it can be accurately determined through photographing by lacrimal cyst angiography, the examination medical staff avoids the risk of exposure damage due to the radiation leaked during the process.
