Description

Technical Field

[0001] This utility model relates to the field of conjunctival sac irrigation technology, and in particular to a disposable conjunctival sac irrigation device. Background Technology

[0002] Ophthalmic surgeries, such as cataract surgery and corneal transplantation, are performed within the conjunctival sac. If the sac is not cleaned after surgery, residual foreign objects and bacteria can easily cause infection and postoperative inflammation, thus affecting the surgical outcome. Furthermore, patients often experience discomfort such as pain, a foreign body sensation, and eye irritation after surgery. Irrigating the conjunctival sac can alleviate these symptoms and help restore vision.

[0003] Therefore, after ophthalmic surgery, doctors often recommend that patients undergo conjunctival sac irrigation multiple times daily to promptly remove residue and bacteria, ensuring postoperative recovery and effectiveness. However, levofloxacin eye drops are frequently used clinically for conjunctival sac irrigation. The bottle cap has a pointed tip that allows the eye drops to be opened by tightening the cap. While this opening is sufficient for daily eye drops, it's too small for preoperative conjunctival sac irrigation. Simply designing a larger opening to meet irrigation needs presents the following problems: When irrigating the conjunctival sac, the patient lies on the bed, and medical staff need to invert the bottle at a certain angle for better irrigation. However, with the larger opening, the eye drops can easily leak out, making it inconvenient for medical staff to use. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems of the above-mentioned disposable conjunctival sac irrigation device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a disposable conjunctival sac irrigation device, which solves the problem of the current clinical use of levofloxacin eye drops for rinsing the conjunctival sac. The bottle cap has a pointed tip on the inside, which can be opened by tightening the cap. As a daily eye drop, this opening can meet clinical needs. However, it is too small for preoperative conjunctival sac irrigation. If the opening is designed to be larger to meet the irrigation needs, the following problems exist. When rinsing the conjunctival sac, the patient is lying on the bed, and medical staff need to invert the bottle at a certain angle to better rinse the conjunctival sac. When the bottle is inverted at an angle, the eye drops in the bottle can easily flow out directly due to the large opening, which is inconvenient for medical staff to use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a disposable conjunctival sac irrigation device, comprising:

[0008] The main unit includes a medicine bottle, a bottleneck fixed and connected to the medicine bottle, a threaded cylinder fixed and connected to the bottleneck, a conduit fixed and connected to the threaded cylinder, a semi-circular flushing tube fixed and connected to the conduit, a nozzle fixed and connected to the end of the semi-circular flushing tube away from the bottleneck, and a threaded cap threadedly connected to the threaded cylinder.

[0009] The control unit includes a baffle fixed inside a conduit, the baffle having a circular hole, and a plug for blocking the circular hole being disposed inside the conduit.

[0010] In a preferred embodiment of the disposable conjunctival sac irrigation device of this utility model, the length of the threaded cap is greater than the sum of the lengths of the catheter, the semi-circular irrigation tube, and the threaded cylinder.

[0011] In a preferred embodiment of the disposable conjunctival sac irrigation device of this utility model, a hollow plate is fixed together on the catheter and the semi-circular irrigation tube, a through groove is opened in the hollow plate, and a rubber ring is fixed in the catheter.

[0012] In a preferred embodiment of the disposable conjunctival sac irrigation device of this utility model, a cylindrical rod is fixed on one side of the plug, and the cylindrical rod passes through the rubber ring and slides in a sealed manner within the rubber ring. The cylindrical rod also passes through the through groove and slides within the through groove.

[0013] In a preferred embodiment of the disposable conjunctival sac irrigation device of this utility model, a pressure plate is fixed to the outside of the cylindrical rod, and the pressure plate is located inside the hollow plate.

[0014] In a preferred embodiment of the disposable conjunctival sac irrigation device of this utility model, a spring is sleeved on the outer side of the cylindrical rod, with one end of the spring abutting against the pressure plate and the other end of the spring abutting against the inner wall of the hollow plate.

[0015] The beneficial effects of this invention are as follows: Medical staff hold the medicine bottle upside down, tilting the semi-circular irrigation tube and the conjunctival sac at an angle. Then, they squeeze the bottle to release the eye drops from the stopper. Once the stopper is removed from the round hole, the eye drops are discharged from the round hole, the semi-circular irrigation tube, and the nozzle, thus rinsing the patient's conjunctival sac. During this process, when the medical staff does not squeeze the bottle, the stopper blocks the round hole, preventing the eye drops from flowing out. This allows the medical staff to easily adjust the semi-circular irrigation tube and nozzle to the appropriate angle with the conjunctival sac before rinsing. Attached Figure Description

[0026] Reference Figures 1-4 As one embodiment of the present invention, a disposable conjunctival sac irrigation device is provided, comprising:

[0027] The main unit 100 includes a medicine bottle 101, a neck 102 fixed and connected to the medicine bottle 101, a threaded cylinder 103 fixed and connected to the neck 102, a conduit 104 fixed and connected to the threaded cylinder 103, a semi-circular flushing tube 105 fixed and connected to the conduit 104, a nozzle 107 fixed and connected to the end of the semi-circular flushing tube 105 away from the neck 102, and a threaded cap 106 threadedly connected to the threaded cylinder 103. The length of the threaded cap 106 is greater than the sum of the lengths of the conduit 104, the semi-circular flushing tube 105, and the threaded cylinder 103.

[0028] The control unit 200 includes a baffle 201 fixed inside the conduit 104, a circular hole 202 is provided in the baffle 201, and a plug 203 for blocking the circular hole 202 is provided inside the conduit 104.

[0029] When it is necessary to irrigate the patient's conjunctival sac, first rotate the threaded cap 106 to remove it from the threaded cylinder 103. Then, the medical staff holds the medicine bottle 101 and inverts it so that the semi-circular irrigation tube 105 and the conjunctival sac are at an angle. At this time, the stopper 203 blocks the round hole 202, and the eye drops will not flow out. During irrigation, the medical staff squeezes the medicine bottle 101 to squeeze the stopper 203. When the stopper 203 is removed from the round hole 202, the eye drops are discharged from the round hole 202, the semi-circular irrigation tube 105, and the nozzle 107, and the patient's conjunctival sac can be irrigated. During this process, the eye drops will not flow out when the medical staff does not squeeze the medicine bottle 101, which makes it convenient for the medical staff to adjust the semi-circular irrigation tube 105 and the nozzle 107 to the appropriate angle with the conjunctival sac before irrigating.

[0030] In addition, a hollow plate 204 is fixed together on the conduit 104 and the semi-circular flushing pipe 105. A through groove 208 is opened in the hollow plate 204. A rubber ring 209 is fixed in the conduit 104. A cylindrical rod 205 is fixed on one side of the plug 203. The cylindrical rod 205 passes through the rubber ring 209 and is located in the rubber ring 209 for sealing and sliding. The cylindrical rod 205 passes through the through groove 208 and is located in the through groove 208 for sliding. A pressure plate 206 is fixed on the outside of the cylindrical rod 205. The pressure plate 206 is located in the hollow plate 204. A spring 207 is sleeved on the outside of the cylindrical rod 205. One end of the spring 207 abuts against the pressure plate 206, and the other end of the spring 207 abuts against the inner wall of the hollow plate 204.

[0031] It should be noted that, under normal conditions, the stopper 203 blocks the round hole 202. When the stopper 203 is squeezed by the eye drops, it moves out of the round hole 202. At this time, the pressure plate 206 compresses the spring 207. When the medical staff does not squeeze the medicine bottle 101, the stopper 203 blocks the round hole 202 again under the rebound force of the spring 207. The hollow plate 204 is designed to prevent metal substances from reacting with the eye drops by placing the spring 207 inside the hollow plate 204, thus preventing the eye drops from being contaminated.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
