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 discloses hydrogel beads for treating keratitis and their use during sleep. Polyvinyl alcohol (PVA) is dissolved in water and heated, followed by heating water-soluble short-chain chitosan (CS) and stirring until dissolved to obtain a PVA / CS mixed solution. Tobramycin is dissolved in water, followed by addition of terephthalic acid and baicalin, and ultrasonication until completely dissolved to obtain a TOB / BA mixed solution. The PVA / CS mixed solution is then added dropwise to the TOB / BA mixed solution, where the droplets form hydrogel beads under gravity, resulting in hydrogel beads for treating keratitis. The hydrogel microspheres continuously degrade and release TOB and BA during sleep. TOB exhibits broad-spectrum antimicrobial activity, while BA promotes the transformation of macrophages from M1 to M2 morphology and scavenges reactive oxygen species, achieving simultaneous antibacterial, anti-inflammatory, and antioxidant effects. In vivo experiments in a rabbit corneal S. aureus infection model further confirmed that the PCBT hydrogel microspheres exhibit superior therapeutic efficacy and clinical potential compared to existing commercially available eye drops, making them suitable for the treatment and management of BK during sleep.

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.
