Description

Technical Field

[0001] The invention relates to the technical field of conjunctival sac flushing, in particular to an ophthalmic conjunctival sac flushing device. Background Art

[0002] Conjunctival sac irrigation is a common ophthalmic procedure used to clear secretions from the conjunctival sac, wash the eye before special foreign body examinations, and provide emergency irrigation after chemical burns. It is also a routine preoperative preparation for ophthalmic surgery. Currently, conjunctival sac irrigation methods mostly use needle-free "infusion" methods, handheld water bottles, and needle-free syringe aspiration.

[0003] When using the ophthalmic conjunctival sac irrigation device on the market, the medical staff holds the irrigation liquid in one hand to irrigate the conjunctival sac, and uses the other hand to hold the patient's eyelid with a cotton swab or to wipe with gauze, adjust the flow of the irrigation liquid, etc. Usually, the patient himself or his companion 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 clothes. It is not convenient for one person to operate, which 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 irrigation when the patient is in a side-lying or sitting position. Although it can facilitate the close fit of the water receiver to 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 respectively before it can fit the patient's eyes. It has certain limitations and is inconvenient for the operator to use. Summary of the Invention

[0037] When using the ophthalmic conjunctival sac irrigation device on the market, medical staff hold the irrigation liquid in one hand to flush the conjunctival sac, and use the other hand to use a cotton swab to hold the patient's eyelid open or take gauze to wipe, adjust the flow of irrigation liquid, etc. Usually, the patient himself or her companion 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. It is not convenient for one person to operate, which affects work efficiency.

[0038] In the related art, a rotating water receiver is provided to fit tightly around the patient's eyes, and the damping of a universal damping ball head is used to prevent the water receiver from rotating at will. This is suitable for flushing when the patient is in a side-lying or sitting position. Although this allows the water receiver to fit tightly around the patient's eyes, the position of the water receiver is not convenient to adjust in actual use. The water receiver needs to be adjusted and fixed up and down and left and right in turn before it can fit around the patient's eyes. This has certain limitations and is inconvenient for the operator to use.

[0039] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an ophthalmic conjunctival sac irrigation device. When it needs to be used, it is only necessary to pull the mounting block 16 up and down and left and right, adjust the position of the water receiver 17, rotate the adjustment rod 21, fix the position of the plate body 14, and complete the adjustment. It is more convenient and quick, and improves the convenience of the device.

[0040] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0042] After using the splint 11 to fix the support assembly 1 in the specified position, manually pull the mounting block 16 so that when the mounting block 16 slides up and down, it drives the fixing block 15 and a plate body 2 14 to slide out from the plate body 1 13, thereby adjusting the height of the fixing block 15 and the mounting block 16. At the same time, pull the mounting block 16 laterally so that it pulls the other plate body 13 to slide out from the plate body 2 14, thereby adjusting the lateral position of the mounting block 16. Finally, turn the adjusting rod 21 so that the adjusting rod 21 drives 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 so that the slider 24 slides laterally in the plate body 2 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 first step is to move the first rod 25 and squeeze the spring 26 until the outer ends of the two round-headed rods 25 are respectively pressed against the two plate bodies 13, and the position between the two plate bodies 13 and the two plate bodies 2 14 is locked, thereby completing the adjustment of the up and down, left and 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 wrapped 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 so that it is connected to the other water tank 12. When flushing, the water receiver 17 is closely fitted to the patient's eyes, and 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 flushing 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-headed rod 2 32 is pulled outward to slide one end of the rod out from the plate 1 13, and then the plate 1 13 is pulled outward to separate the plate 1 13 from the plate 2 14, completing the disassembly. Conversely, the installation is completed, which facilitates the maintenance of the separated equipment.

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

[0045] In some embodiments, the interior of the adjustment box 43 is composed of a bevel gear set 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 it drives the threaded rod to rotate through the bevel gear set, and the push plate 44 is threadedly connected to the threaded rod, so that the push plate 44 slides up and down to achieve adjustment.

[0046] In some embodiments, the round-headed 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-headed 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 provided 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.

[0048] In some embodiments, a sliding assembly 5 is provided on the outside of the shell 31; the sliding assembly 5 includes: a ring body 51 slidably connected to the outside of the shell 31, the shaping rod 34 is fixedly connected to the ring body 51; and a positioning ring 52 is fixedly connected to one end of the shaping rod 34.

[0049] During use, after adjusting the position of the mounting block 16 and the water receiver 17, manually push the ring body 51 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 to adjust the position of the mounting block 16. At the same time, the position of the ring body 51 is adjusted, 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.

[0051] In some embodiments, the sliding assembly 5 also includes: a tightening bolt 54 threadedly connected to the ring body 51, and the connecting rod 53 passes through the ring body 51, and one end of the tightening bolt 54 is tightly pressed against the connecting rod 53. When in use, the tightening bolt 54 is rotated to separate one end of the tightening bolt from the connecting rod 53, and then the ring body 51 is pushed so that the ring body 51 can slide horizontally on the shell 31, thereby changing the distance between the mounting block 16 and the ring body 51 and improving the scope of application.

[0052] In some embodiments, the length of the connecting rod 53 is equal to the length of the shell 31 , and the anti-ring body 51 affects the normal use of the round head rod 32 .
