Integrated lacrimation retarder and matched placing device thereof

Abstract

The invention discloses an integrated lacrimation retarder and a matched placing device thereof. The integrated lacrimation retarder is in an integrated design and comprises a front hollow mushroom-type closing head, a middle hollow cylinder structure and a bowl-shaped flange. The matched placing device of the integrated lacrimation retarder is in a syringe design and comprises a front gradually-narrowed push injecting channel, a middle piston and a rear internal push rod pushing unit, wherein the push injecting channel is provided with a thin tip which can enter a dacryon; the front part of the piston is a solid cylinder which is in nested connection with the hollow cylinder structure of the integrated lacrimation retarder, and the middle of the piston is an elastic sponge. The integrated lacrimation retarder and the matched placing device of the integrated lacrimation retarder are tightly preassembled together, an operator can insert the front tip of the syringe type placing device into the dacryon and push the piston to plant the integrated lacrimation retarder into a lacrimal passage to complete operation with one hand, thereby achieving use convenience. The integrated lacrimation retarder can be effectively and tightly fit with the lacrimal passage to retard lacrimation and further to effectively relieve xerophthalmia.

Description

technical field [0001] The invention relates to a retarder for treating dry eye syndrome, in particular to an integrated tear outflow retarder and a matching installation device. Background technique [0002] Dry eye syndrome is a general term for various diseases that lead to a decrease in the stability of the tear film, such as abnormal tear quality or quantity, accompanied by ocular discomfort and / or ocular surface tissue lesions. Common symptoms include dry eyes, easy tiredness, itchy eyes, foreign body sensation, etc. [0003] With the rapid increase in the number of mobile phone users in our country, more than 50% of users use mobile phones for more than 5 hours a day. There are more and more drivers and late-night workers. Most patients with eye diseases use eye drops irregularly. Since eye drops generally contain preservatives, preservatives can damage the epithelial cells of the ocular surface, causing damage to the tear film, and easily forming dry eyes. , Extensi...

AI Technical Summary

Problems solved by technology

[0004] At present, we mostly choose artificial tears for the treatment of dry eye, but its treatment can only achieve temporary relief, and has little effect on patients with severe dry eye

[0005] Aiming at the disadvantages of the existing technology, we try to design an integrated tear outflow delayer and its matching installation device, in order to achieve the purpose of long-term relief of dry eye and reduce the use of uninterrupted artificial tears for patients, especially for those who are treated with drugs Patients with severe dry eye who are not effective will have a significant improvement
