Eye drop device

Abstract

The invention relates to an eye drop device. The eye drop device comprises:a central cylinder; two elastic jaws,wherein the two elastic jaws are symmetrically arranged at a first end of the central cylinder and are arranged in a figure-eight shape on both sides of the axis of the central cylinder, the two elastic jaws are used to open the upper and lower eyelids when the eye drops are injected; adrug guiding tube assembly, the drug guiding tube assembly is used for guiding the eye drops during the dropping, and the first end along the axis of the central cylinder passes through the central cylinder from the second end of the central cylinder andthe first end of the central cylinder is exposed; wherein the drug guiding tube assembly is rotatably disposed on the central cylinder, the secondend of the drug guiding tube assembly is used for securing the ophthalmic vial and enabling the ophthalmic vial to be communicated with the drug guiding tube assembly, the first end of the drug guiding tube assembly is used for facing the eyes and injecting the eye drops into the eyes. The eye drop device enables the eye drops to be accurately instilled into the patient's conjunctival sac, whileavoiding the injection of the eye drops into the outside of the eyes, and avoiding contact infection with the eyes, thereby achieving high quality and efficient infusion of the eye drops.

Description

technical field [0001] The invention relates to the technical field of medical devices, more specifically, to an eye dropper for ophthalmology. Background technique [0002] Eye drops are one of the most commonly used pharmaceutical dosage forms for eye diseases. For many eye diseases, eye drops have direct and quick therapeutic effects. The eye drops are directly instilled through the eye drops bottle. Due to reasons such as arm shaking, accurate and stable positioning of the bottle mouth cannot be achieved. The bottle mouth is easy to touch the cornea of ​​the patient's eye, stimulating the patient to blink, and causing the patient's contact infection; On the one hand, this form of instillation is easy to drip the eye drops to the outside of the eye, resulting in waste of liquid medicine. [0003] Although there are some eye droppers in the prior art, there are also problems of simple structure or unreasonable design, which makes the expected effect of instillation unsati...

Problems solved by technology

The eye drops are directly instilled through the eye drops bottle. Due to reasons such as arm shaking, accurate and stable positioning of the bottle mouth cannot be achieved. The bottle mouth is easy to touch the cornea of ​​the patient's eye, stimulating the patient to blink, and causing the patient's contact infection; On the one hand, this form of instillation is easy to drip the eye drops to the outside of the eye, resulting in waste of liquid medicine

[0003] Although there are some eye droppers in the prior art, there are also problems of poor structure or unreasonable design, which makes the expected effect of instillation unsatisfactory
