AI Technical Summary
Existing ophthalmic medication application devices tend to have medication sticking to the inside when using ointment-like medications, making cleaning difficult and limiting the number of times they can be reused.
A structure including a cartridge, syringe, interface, cavity, hollow tube, clamp, and clamp is designed. The clamp and elastic pressure roller push the ointment medicine and squeeze the medicine out through the hollow tube to avoid the medicine coming into contact with the inner wall. The hollow tube can be easily replaced through the interlocking structure of the locking block and the connector.
This reduces the difficulty of cleaning the medication application device, avoids drug waste, enables sterile replacement and recycling of the device, and prevents cross-infection.

Technical Field
[0001] This utility model relates to the field of ophthalmic technology, specifically to an ophthalmic ointment application device. Background Technology
[0002] In ophthalmology, doctors often administer eye drops to patients to treat eye diseases. However, eye drops need to be instilled into the eyelids to be effective. Different medications are used depending on the eye disease. In addition to liquid eye drops, there are also ointments. Liquid eye drops and ointments are commonly used treatments in ophthalmology.
[0003] Existing ophthalmic medication application devices fall into two categories: one involves manually opening the eye to drip or squeeze in the medication, which is commonly used for liquid medications; the other uses an application device. For ointment-type medications, the stickiness of the ointment causes the inner wall of the application device to become adhered to the ointment, making it difficult to clean. Furthermore, with prolonged use, the ointment can solidify inside the application device. Due to the limited internal space, it is not easy to scrape and clean the deep inside. This eventually renders the application device unusable, limiting its reusability.
