Comprising a liquid storage container, a liquid outlet valve, a dripping nozzle and a gland, the liquid outlet valve is arranged at one end of the liquid storage container and comprises a fixing seat and a valve rod located on a top plate of the fixing seat, and a first liquid outlet is formed in the top plate; the gland is connected to one end of the liquid outlet container and covers the liquid outlet valve; the drip nozzle comprises a drip nozzle part and an elastic piece which is located at the lower end of the drip nozzle part and can elastically deform, the drip nozzle part covers the valve rod, the upper end of the drip nozzle part extends out of the gland, the elastic piece is located between the gland and the top plate, and a second liquid outlet is formed in the top of the drip nozzle part. A liquid outlet channel is formed between the valve rod and the drip nozzle part and between the elastic sheet and the top plate, and the top of the valve rod blocks the second liquid outlet in a normal pressure state; bacteria blocking is achieved in a physical mode, and safety and reliability are achieved.

The present disclosure provides suspendable ophthalmic solutions with excellent redispersibility. The present disclosure provides an aqueous suspension agent comprising (E)-2-(7-trifluoromethylchroman-4-ylidene)-N-(7-hydroxy-5,6,7,8-tetrahydronaphthalen-1-yl)acetamide or a pharmaceutically acceptable salt or solvate thereof, a cellulosic polymer, and a nonionic surfactant.

The utility model provides a medicine dripping device for the ophthalmology department, and belongs to the technical field of medicine dripping devices. Comprising a positioning box and an eyeshade installed at the bottom end of the positioning box, a storage bin is formed in the top end of the positioning box, sliding grooves are formed in the two ends of the positioning box, a medicine storage bag is fixedly embedded in the bottom end of the positioning box, a push plate is slidably inserted into the top end of the positioning box, and clamping grooves are formed in the two sides of the inner wall of each sliding groove; sliding parts embedded in the sliding grooves are fixed to the two ends of the push plate, and clamping plates are inserted into the clamping grooves in a damping mode. The pushing plate is pushed by the extruding plate to move downwards to extrude the medicine storage bag, the sliding parts at the two ends of the pushing plate abut against the clamping plate in the extruding process, the extruding and moving stroke of the pushing plate is controlled by adjusting the position of the clamping plate, and therefore the extruding amount of liquid medicine is accurately controlled, and the situation that too much liquid medicine is extruded, and waste of eye drops is caused is avoided.

The utility model discloses a medicine dropping device for ophthalmology, which relates to the technical field of medical treatment and comprises a clamping piece, clamping heads are fixed at the lower ends of two sides of the clamping piece, pressing pieces are clamped at the clamping heads, a through hole is formed in the middle of the surface of the clamping piece in a penetrating manner, a clamping seat is fixed at the through hole, and an eyedrop bottle is inserted on the clamping seat in an inverted manner. A rubber sleeve piece is fixed to the inner wall of the clamping base and used for improving the inserting stability of the eyedrop bottle. According to the medicine dropping device for the ophthalmology department, the two pressing pieces are pinched by hands, the two rubber shifting pieces are matched to push the upper eyelid and the lower eyelid aside, meanwhile, the squeezing plates on the outer surfaces of the pressing pieces can squeeze the eyedrops bottle, eyedrops penetrate through the through opening and drop on the eyeball, the eyelid opening effect can be effectively guaranteed in the whole process, and the eyedrops are prevented from falling off. The treatment effect is ensured.

The cornea covering device comprises a storage bin, an arc-shaped supporting seat is arranged on the inner wall of the storage bin, the cornea covering device is stored on the inner wall of the storage bin, the cornea covering device is used for the strabismus surgery of the ophthalmology department, a cavity is formed in the cornea covering device, a light shielding plate is arranged on the top of the cornea covering device, and the arc-shaped supporting seat is arranged on the light shielding plate. A covering piece is arranged at the bottom of the cornea covering device, eyedrops are stored in the cornea covering device, a cavity is formed in the cornea covering device, the effect of conveniently storing the eyedrops through the cavity is achieved, meanwhile, the covering piece with micropores is arranged at the bottom of the cornea covering device, and therefore the cornea covering device is convenient to use. The eyedrops can slowly permeate into the cornea of the patient through the micropores in the surface of the covering sheet, so that the cornea of the patient is moisturized, and the comfort level is improved.

The present disclosure provides suspendable ophthalmic solutions with excellent redispersibility. The present disclosure provides an aqueous suspension agent comprising (E)-2-(7-trifluoromethylchroman-4-ylidene)-N-(7-hydroxy-5,6,7,8-tetrahydronaphthalen-1-yl)acetamide or a pharmaceutically acceptable salt or solvate thereof, a cellulosic polymer, and a nonionic surfactant.

The present invention relates to a preservative-free aqueous solution in the form of eye drops packaged in a container that ensures product stability, an ideal drop volume and less variability in drop volume, as well as providing efficient dosing.

The utility model discloses an eye drop medicine adding frame, including frame, have the cavity, the baffle that can fix eye drop bottle is equipped in the cavity, the baffle has the bayonet for the neck of eye drop bottle carding, fixed element, be located in the lateral wall of cavity, push and resist eye drop bottle and lean on the baffle, add liquid element, slidingly set up in the frame, including sliding limit piece, communicating pipe spare and needle guide piece, needle guide piece is equipped in one end of communicating pipe spare, the other end of communicating pipe spare can approach or be far from the bottle mouth of eye drop bottle, the syringe needle passes through the passage in the inside of communicating pipe spare by needle guide piece, enters eye drop bottle through the bottle mouth of eye drop bottle, and sliding limit piece restricts the sliding distance of adding liquid subassembly. The utility model can not directly hold eye drop bottle, and simultaneously needle guide piece guides the syringe needle and inserts eye drop bottle, avoids the syringe needle and stabs hand, and also can accurate and stab into eye drop bottle and add medicine.
