[0002] Flushing the conjunctival sac is a common ophthalmic care operation, used to remove secretions in the conjunctival sac, wash the eyes before special foreign body examinations, and wash urgently after chemical burns. It is also a routine preoperative preparation for ophthalmic surgery. Currently, most methods for flushing the conjunctival sac use needle-free "infusion" method, hand-held kettle method, and needle-free syringe suction flushing method.

[0003] When using the ophthalmic conjunctival sac flushing device on the market, the medical staff holds the flushing liquid in one hand to flush the conjunctival sac, and uses the other hand to hold the patient's eyelid open with a cotton swab or to wipe with gauze, adjust the flushing liquid flow, etc. Usually, the patient himself or a caregiver or another medical staff member is required to help fix the water receiver with his hands. The water receiver needs to be close to the patient's face to prevent the liquid from contaminating the head, face and clothing, which is not convenient for single-person operation and affects work efficiency. In the related art, a rotating water receiver is set to fit the patient's eyes tightly, and the damping of the universal damping ball head is used to prevent the water receiver from rotating at will. It is suitable for flushing when the patient is in a side-lying or sitting position. Although it can facilitate the close fit of the water receiver and the patient's eyes, in actual use, the position of the water receiver is not convenient to adjust. The water receiver needs to be adjusted and fixed up and down and left and right in turn before it can fit the patient's eyes. It has certain limitations and is inconvenient for the operator to use.

[0042] After the support assembly 1 is fixed in the specified position using the clamping plate 11, the mounting block 16 is manually pulled to make the mounting block 16 slide up and down, thereby driving the fixing block 15 and a plate body 14 to slide out from the plate body 13, so as to adjust the height of the fixing block 15 and the mounting block 16. At the same time, the mounting block 16 is pulled laterally to make it pull the other plate body 13 to slide out from the plate body 14, so as to adjust the lateral position of the mounting block 16. Finally, the adjusting rod 21 is rotated to make the adjusting rod 21 drive the two threaded rods 22 to rotate through the bevel gear 23, and then the threaded connection between the threaded rod 22 and the slider 24 is made to make the slider 24 slide laterally in the plate body 14 until the slider 24 contacts the inner end of the round head rod 1 25, slides along the inclined surface of the inner end of the round head rod 1 25, and pushes the round head rod 1 25 to slide outward. The spring 1 26 is pressed until the outer ends of the two round-headed rods 1 25 are respectively pressed against the two plate bodies 1 13, and the positions between the two plate bodies 1 13 and the two plate bodies 2 14 are locked, so as to complete the adjustment of the up-down and left-right positions of the mounting block 16 and the water receiver 17. Finally, after the water supply pipe and the drainage pipe are respectively connected to the two water tanks 12, the water supply pipe is wound around the outside of the shaping rod 34, and one end of the water supply pipe is directed toward the water receiver 17. The drainage pipe is connected to the bottom of the water receiver 17 to make it communicate with the other water tank 12. When flushing, the water receiver 17 is closely fitted to the patient's eyes. The cleaning liquid is passed through the water supply pipe by the submersible pump in the water supply tank 12 to perform the conjunctival sac flushing operation. The flushed water flows back to the other recovery water tank 12 through the drainage pipe to complete the cleaning action.

[0043] When cleaning is completed or the equipment needs to be repaired, the round head rod 2 32 is pulled outward to make one end of the round head rod 2 slide out from the plate body 13, and then the plate body 13 is pulled outward to separate the plate body 13 from the plate body 2 14, and the disassembly is completed. Conversely, the installation is realized, which is convenient for the maintenance of the separated equipment;

[0044] When in use, when the adjusting rod 21 is rotated clockwise, the slider 24 slides in the direction close to the round head rod 1 25, and at the same time, the rod body 41 is driven to rotate through the gear set 42, and then the height of the push plate 44 is adjusted through the adjustment box 43, so that when the slider 24 slides toward the round head rod 1 25, the push plate 44 slides in the direction away from the round head rod 2 32, and conversely, when the slider 24 moves away from the round head rod 1 25, the push plate 44 pushes the round head rod 2 32 downward, thereby canceling the limit on the plate body 13, facilitating subsequent disassembly.

[0045] In some embodiments, the interior of the adjustment box 43 is composed of a bevel gear group and a threaded rod, the threaded rod is threadedly connected to the push plate 44, and the threaded rod is connected to the rod body 41 through a bevel gear transmission. When in use, when the rod body 41 rotates, one end of the rod drives the threaded rod to rotate through the bevel gear group, and the push plate 44 is threadedly connected to the threaded rod to slide up and down to achieve adjustment.

[0046] In some embodiments, the round head rod 2 32 and the spring 2 33 are a group, and multiple groups are provided on the shell 31. When in use, multiple round head rods 2 32 are inserted into the plate body 13 at the same time, which has a better limiting effect on the plate body 13 and makes its sliding more stable.

[0047] In some embodiments, the round head rod 25 and the spring 26 are a group, and multiple groups are arranged in each of the plate bodies 14. When in use, multiple round head rods 25 are pressed against the inner side of the plate body 13 at the same time to improve the fixing effect.

[0049] When in use, after adjusting the position of the mounting block 16 and the water receiver 17, the ring body 51 is manually pushed to slide on the outside of the shell 31, thereby adjusting the position of the shaping rod 34 and the positioning ring 52, thereby facilitating the water supply pipe to align with the flushing position and facilitating the conjunctival sac flushing operation.

[0050] In some embodiments, the sliding assembly 5 also includes: a connecting rod 53 is arranged on one side of the ring body 51, and one end of the connecting rod 53 is connected to the mounting block 16. When in use, when the position of the mounting block 16 is adjusted, it pulls the connecting rod 53 and the ring body 51, so that when the position of the mounting block 16 is adjusted, the position of the ring body 51 is adjusted at the same time, thereby ensuring that the distance between the shaping rod 34 and the positioning ring 52 and the water receiver 17 remains unchanged, thereby facilitating the flushing operation.
