Abstract

An ophthalmic drug delivery device comprises a shell, a pushing device and an injection device, the pushing device and the injection device are installed on the shell, a speed reducing mechanism is connected between the pushing device and the injection device, and the pushing device pushes the injection device after being decelerated through the speed reducing mechanism. The advancing distance of the injection device is smaller than the propelling distance of the pushing device, so that the dosage error of eye administration is reduced, and the accuracy of eye micro-administration is improved.

Description

technical field [0001] The present invention relates to the technical field of medicine, and more specifically, relates to an ophthalmic drug delivery device. Background technique [0002] The eyeball is a sensory organ with a very delicate structure and extremely complex functions, especially the back of the eyeball, which has a fine and complex structure and plays an important role in maintaining normal visual function. Diseases in the back of the eye often cause serious damage to visual function, or even complete blindness . [0003] Ocular drug delivery is the main means of ophthalmic treatment. In order to achieve the dosage of drugs at the back of the eye, retrobulbar injection has been used clinically. This type of drug delivery is the most direct way to deliver drugs to the posterior segment of the eye. The drug gathers rapidly near the retina and vitreous body, and the concentration of the drug in the back tissue of the eye can reach a high level, with quick onset,...
