Description

Technical Field

[0001] This utility model belongs to the field of ophthalmic lumen instrument cleaning technology, specifically relating to a multi-channel cleaning rack for ophthalmic lumen instruments. Background Technology

[0002] Ultrasonic emulsification handpieces, irrigation needles, and I / A handpiece-type ultrasonic emulsification aspiration devices are the most commonly used reusable instruments in ophthalmic surgery. To avoid cross-infection, these instruments must be cleaned, disinfected, and sterilized after each ophthalmic surgery. Cleaning is the first step. Currently, commercially available ophthalmic cleaning frames can only clean one side of the lumen, but ultrasonic emulsification lumens are bilateral. Therefore, only one side can be cleaned during the cleaning process, while the other side must be cleaned again by the cleaning machine or manually. This is not only time-consuming and labor-intensive, reducing work efficiency, but also results in incomplete cleaning. It cannot avoid the uncertainties of human operation in cleaning the lumen instruments, and cannot guarantee the cleaning effect of the lumen instruments. Utility Model Content

[0003] This invention provides a multi-channel cleaning rack for ophthalmic tubular instruments to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted in this utility model is as follows: a multi-channel cleaning frame for ophthalmic tubular instruments, which is provided with a connecting tube. The connecting tube includes: a rigid fixing head connected to the connecting tube, with a suction-aiding connection part at one end away from the connecting tube for detachable connection with the suction-aiding hole of the infusion handle; and an elastic flexible tube located on the side of the rigid fixing head, with an infusion connection part at the front end for sealed connection with the infusion hole of the infusion handle.

[0005] In a preferred embodiment, the suction-aiding connection is a threaded fastener with an embedded nylon ring for screwing into the suction-aiding hole of the injection handle to form an axial seal.

[0006] In a preferred embodiment, the suction-aiding connection is a spring sleeve with a retaining bead and a retaining spring on its inner wall for engaging with the groove on the outer wall of the suction-aiding port.

[0007] In a preferred embodiment, the end of the suction-aiding connector is provided with a tapered guide surface for assisting alignment and extending into the suction-aiding hole.

[0008] In a preferred embodiment, the outer wall of the injection connection is provided with an annular sealing flange, and the flange is provided with anti-slip teeth.

[0009] In a preferred embodiment, the injection connection is provided with a radial expansion groove, which generates radial deformation when under pressure to fit tightly against the inner wall of the injection hole.

[0010] In a preferred embodiment, the connecting pipe is further provided with dual liquid supply channels that respectively connect the rigid fixing head and the elastic hose.

[0011] In a preferred embodiment, the dual-channel liquid supply is equipped with a flow regulating valve, and the flow regulating valve is provided with a scale.

[0012] In a preferred embodiment, the connecting pipe is further provided with an elastic groove, and both the rigid fixing head and the elastic hose are provided with protrusions that cooperate with the elastic groove for fixing the position of the rigid fixing head and the elastic hose.

[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. As a preferred embodiment of this utility model, by installing an elastic hose on the side of a rigid fixing head, one side of the instrument is fixed to the rigid fixing head, and the other side is connected by a connector of the elastic hose, so that the two channels can be flushed at the same time. This ensures the cleaning effect of the instrument while reducing the manual labor of the staff and improving work efficiency.

[0015] 2. As a preferred embodiment of this utility model, the rigid fixing head and the suction port of the injection handle are tightly fixed by threaded fasteners, which improves the reliability and fastening force of the rigid fixing head and the suction port, and is easy to disassemble and reuse. The embedded nylon ring can prevent liquid leakage and ensure the sealing of the connection between the two.

[0016] In addition, when the suction aid connection is set as a spring sleeve, the elastic structure of the snap ring can achieve one-click insertion and removal, making installation and disassembly more efficient. The snap ball is inserted into the groove on the outer wall of the suction port under the spring pressure, forming a stop to prevent axial pull-out, ensuring the tightness of the connection between the two and improving the efficiency of loading and unloading.

[0017] At the same time, by setting a tapered guide surface, a positioning function is provided to assist in the precise alignment of the suction hole, avoid misalignment, and extend into the suction hole. The tapered slope also ensures a tight fit with the suction hole, improving the connection between the rigid fixing head and the suction hole.

[0018] 3. As a preferred embodiment of this utility model, an annular sealing flange is provided on the outer wall of the filling connection part. The sealing and locking properties between the elastic hose and the filling hole are enhanced by elastic deformation. The diameter of the annular sealing flange is slightly larger than the inner diameter of the mating hole. After insertion, it forms a circumferential seal to block liquid leakage. This design also prevents loosening after insertion and improves the efficiency of loading and unloading.

[0019] In addition, when the injection connection is provided with a radial expansion groove, the radial expansion groove will deform radially when under pressure to fit tightly against the inner wall of the injection hole, thereby achieving the connection between the elastic hose and the injection hole and preventing the injection hole from loosening.

[0020] 4. As a preferred embodiment of this utility model, independent liquid supply can be achieved by setting a dual-channel liquid supply system in the connecting pipe. The dual channels can transport different types of fluids separately, avoiding mixing and contamination.

[0021] Meanwhile, the flow regulating valve installed in the liquid supply channel can achieve independent pressure control, with one high-pressure channel and one low-pressure channel, which can be switched or combined as needed to adapt to different pressure requirements.

[0022] 5. In a preferred embodiment of this utility model, the elastic groove and the rigid fixing head and the protrusion on the elastic hose are provided by the connecting pipe. The protrusion of the elastic groove is retractable and used to fix the position of the rigid fixing head and the elastic hose, and to prevent the rigid fixing head and the elastic hose from loosening on the connecting pipe.

[0039] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] Furthermore, it should be understood in the description of this utility model that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] Example 1:

[0045] A preferred embodiment, such as Figure 1 and Figure 2 As shown, a multi-channel cleaning frame for ophthalmic tubular instruments has a main frame that is a rectangular support. Support plates, fixed within the main frame, are spaced apart along its height. A rotating spray arm connected to the main water inlet is positioned above the lower support plate. The main water inlet is located at the bottom of the main frame and supplies liquid to the connecting pipe 1. The main water inlet is connected to two connecting pipes 1, one on the left and one on the right. A rigid fixing head 2 and an elastic flexible hose 3, mounted on the connecting pipe 1 on the support, are fixedly connected to the suction handle connector. Specifically, the connecting pipe 1 includes a rigid fixing head 2 connected to the connecting pipe 1, with a suction-aiding connection part 21 at the end furthest from the connecting pipe 1. The suction port 4 of the suction handle is detachably connected. During cleaning, the suction port 4 of the suction handle is first fixedly connected to the rigid fixing head 2. The design of the suction connection part allows the suction port 4 to be quickly connected to the rigid fixing head 2 and is not prone to leakage. The elastic hose 3 is located on the side of the rigid fixing head 2, and the front end is provided with a filling connection part 31 for sealing connection with the filling port 5 of the suction handle. Then the filling port 5 is connected to the elastic hose 3. The filling connection part 31 can make the filling port 5 snap into the elastic hose 3 to make it securely connected. After the suction port 4 and the filling port 5 are connected, liquid is sprayed through the connecting tube 1 to rinse them clean.

[0046] In addition, the connecting pipe 1 is also equipped with a dual-channel liquid supply 11 that connects the rigid fixing head 2 and the elastic hose 3 respectively. When the suction port 4 and the irrigation port 5 are connected, liquid can be supplied to the rigid fixing head 2 and the elastic hose 3 through two different liquid supply channels. The dual-channel design reduces the single-channel pressure peak by diverting the liquid, protects the elastic hose 3 from high-pressure impact, and extends its service life. At the same time, the flow regulating valve 12 set in the dual-channel liquid supply 11 is fixed and has a scale, which can adjust the pressure of the two liquid supply channels, so that the suction port 4 and the irrigation port 5 can be flushed at different pressures. This ensures the cleaning effect of the instrument cleaning, reduces the manual labor of the staff, and improves work efficiency.

[0047] Example 2:

[0048] like Figures 3-5 As shown, a multi-channel cleaning frame for ophthalmic tubular instruments, differing from Embodiment 1, features a threaded fastener 22 for the suction connection 21. The threaded fastener 22 has an embedded nylon ring 221, which is screwed into the suction port 4 of the suction handle to form an axial seal. During cleaning, the external thread of the rigid fixing head 2 tightly engages the suction port 4, fixing it to the rigid fixing head 2. The design of the threaded fastener 22 allows for quick connection of the suction port 4 to the rigid fixing head 2, and the embedded nylon ring 221 forms an axial seal, ensuring the suction port 4 is securely connected to the rigid fixing head 2 while maintaining the sealing performance of the suction connection 21.

[0049] In addition, such as Figure 4 and Figure 5 When the suction-assisted connection part 21 is a spring sleeve 23, its inner wall is provided with a retaining bead 231 and a retaining spring 232. During cleaning, the spring sleeve 23 is pulled down, and the retaining spring 232 inside receives pressure, pulling down the outside of the spring sleeve 23 to expose the internal locking part. The suction port is inserted into the spring sleeve 23, and the retaining bead 231 is aligned with the groove 41 on the outer wall of the suction port and locked in. At this time, the outside of the spring sleeve 23 is extended and retracted by the retaining spring 232 and returns to its original position. The spring sleeve 23 and the retaining bead 231 are used to firmly lock the suction port 4, making it difficult to loosen, and the sealing performance can also be guaranteed.

[0050] Meanwhile, the end of the suction-assisted connection part 21 is set as a tapered guide surface 24. The inclined structure of the tapered surface can serve as a guide. Even in blind insertion scenarios, the interface can be quickly aligned through structural cooperation, reducing operation time. When the tapered surface cooperates with the suction-assisted hole 4, the negative pressure or external pressure generated by suction will force the contact surface to fit tightly, forming a dynamic seal.

[0051] Example 3:

[0052] like Figure 6 and Figure 7As shown, a multi-channel cleaning frame for ophthalmic tubular instruments, different from embodiment 1, has an annular sealing flange 32 on the outer wall of the infusion connection 31, and the flange has anti-slip teeth. During installation, the elastic hose 3 extends into the infusion hole 5. The diameter of the annular sealing flange 32 is slightly larger than the inner diameter of the mating hole. After insertion, it can lock the infusion hole 5 to form a circumferential seal. The anti-slip teeth of the flange can form a surface contact seal with the inner wall of the infusion hole 5. Compared with the smooth outer wall, it increases the friction and prevents the elastic hose 3 from falling off. The surface contact seal enhances the sealing performance of the infusion hole 5 and the elastic hose 3.

[0053] In addition, the injection connection 31 is provided with a radial expansion groove 33, which generates radial deformation when under pressure to tightly adhere to the inner wall of the injection hole 5. The purpose of sealing and locking is achieved through elastic deformation. During installation, the elastic hose 3 extends into the injection hole 5, and the radial expansion groove 33 expands outward under pressure, pressing the outer wall of the groove 41 tightly against the inner wall of the injection hole 5 to achieve the purpose of locking the injection hole 5. The compression of the radial expansion groove 33 increases the friction between the two, thus preventing the elastic hose 3 from falling out of the injection hole 5.

[0054] Example 4:

[0055] like Figure 8 As shown, a multi-channel cleaning rack for ophthalmic tubular instruments, differing from Embodiment 1, includes an elastic groove 13 on the connecting tube 1. Both the rigid fixing head 2 and the elastic flexible tube 3 have protrusions 14 that mate with the elastic groove 13, used to fix their positions. In use, the sidewalls of the rigid fixing head 2 and the elastic flexible tube 3 contact the protrusions 14 on the elastic groove 13. A spring inside the protrusion 14 compresses it into the connecting tube 1, causing the protrusions on the rigid fixing head 2 and the elastic flexible tube 3 to engage with the groove in the elastic groove 13. At this point, the spring inside the protrusion 14 relaxes, and the protrusion returns to its original shape. This protrusion acts as a barrier, preventing the rigid fixing head 2 and the elastic flexible tube 3 from falling off the connecting tube 1, thus achieving a fixed connection between the rigid fixing head 2 and the elastic flexible tube 3.
