Abstract

The lacrimal plug with adhesive coating comprises a lacrimal plug and an adhesive layer, and the lacrimal plug is wrapped with the adhesive layer. Slightly hypertonic inorganic salts are added into the adhesive layer, so that the hydration speed of the adhesive layer is increased, adhesive force is quickly generated, and falling or untight pluging is prevented; antibacterial substances are added into the adhesion layer to overcome the defect that lacrimal passage inflammation is generated in the using process of the lacrimal plug; a fluorescent indicating substance is added into the adhesion layer, so that a doctor can conveniently observe whether the lacrimal plug is in place or not by using cobalt blue light.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a punctum plug with an adhesive coating and a manufacturing process thereof. Background technique [0002] Dry eye syndrome refers to a tear secretion disorder eye disease caused by various factors, with dry eyes as the main symptom, often accompanied by itching, foreign body sensation, burning sensation in both eyes, or photophobia, blurred vision, vision fluctuations, etc. Performance. Common symptoms include dry eyes, easy fatigue, itchy eyes, foreign body sensation, burning sensation, sticky secretions, fear of wind, photophobia, and sensitivity to external stimuli; sometimes the eyes are too dry, and there is basically insufficient tear fluid, which stimulates the reflex In severe cases, the eyes will be red and swollen, congested, keratinized, and the corneal epithelium is broken and there are filaments adhered. This kind of damage can cause keratoconjunctival...
