Abstract
Description
Technical Field
[0001] This utility model relates to the field of artificial lens technology, and more specifically, to a packaging structure for artificial lenses. Background Technology
[0002] Intraocular lenses (IOLs) are typically made of synthetic polyacrylate materials, possessing excellent biocompatibility and optical properties. They are implanted into the human eye to restore or improve a patient's vision. Proper preservation of the IOL is crucial to ensuring its proper functioning after implantation. During preservation, it should be stored in a light-protected, sterile environment, avoiding violent vibrations or drastic temperature changes.
[0003] Currently, intraocular lenses (IOLs) are typically stored in vials containing a 0.9% sodium chloride solution. However, this packaging method has the following problems: IOLs are thin and soft, and tend to sink to the bottom of the vial in the solution. Furthermore, the small opening of the vial makes handling during surgery difficult and may damage the IOL. Secondly, the IOL cannot remain stably suspended in the 0.9% sodium chloride solution due to buoyancy, affecting its storage and transportation stability. Utility Model Content
[0004] This invention addresses the problem in existing technologies where intraocular lenses sink to the bottom of the bottle and are difficult to remove. It provides a packaging structure for intraocular lenses that can fix the position of the intraocular lens while also making it easy to remove it from the packaging.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A packaging structure for intraocular lenses includes a bottle body;
[0007] The bottle cap is detachably connected to the bottle body; and
[0008] A crystal holder, detachably connected to the bottle cap, and suspended inside the bottle body when the bottle cap is connected to the bottle body; wherein, the crystal holder includes:
[0009] The connecting part, one end of which is detachably connected to the bottle cap,
[0010] A clamping portion, connected to the other end of the connecting portion, for clamping the intraocular lens, and the clamping portion comprising:
[0011] A slot for receiving the artificial lens, and
[0012] A pair of hooks are provided on both sides of the slot to restrain the intraocular lens within the clamping part.
[0013] In the above solution, when packaging the intraocular lens, the intraocular lens is placed in the slot, and then the displacement of the intraocular lens in the axial direction of the slot is restricted by the hook, thereby preventing the intraocular lens from separating from the lens holder; then the bottle cap is connected to the bottle body to complete the packaging of the intraocular lens.
[0014] Preferably, the maximum distance between the two hooks is equal to the diameter of the main body of the intraocular lens.
[0015] Preferably, the maximum vertical distance between the bottom of the slot and the hook is less than the straddle height of the intraocular lens and greater than the vertical distance between the cut surface of the intraocular lens and the end face of the optical body of the intraocular lens.
[0016] Preferably, the surface shape of the slot matches the surface shape of the support portion of the artificial lens.
[0017] Preferably, the clamping part further includes a through hole, which communicates with the slot along the axial direction of the slot, and the diameter of the through hole is smaller than the diameter of the intraocular lens optical body.
[0018] Preferably, the clamping part further includes a clamping port, which communicates with the card slot along the radial direction of the card slot.
[0019] Preferably, the bottle cap has a connector inside, and the connector is detachably connected to the connecting part.
[0020] Preferably, the total length of the crystal holder is between 2 / 3 and 5 / 6 of the total length of the bottle.
[0021] The beneficial effects of this utility model solution are:
[0022] 1. Secure the intraocular lens within the packaging structure without damage and ensure stable storage of the intraocular lens in the preservation solution.
[0023] 2. When storing or using the intraocular lens, it can be easily accessed from the packaging structure without damaging the intraocular lens. Attached Figure Description

[0036] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0037] Example 1
[0038] like Figure 1-4The illustrated packaging structure for an intraocular lens includes a bottle cap 1 and a bottle body 2; the bottle cap 1 and the bottle body 2 are detachably connected; it also includes a lens holder 3, which is detachably connected to the bottle cap 1. When the bottle cap 1 and the bottle body 2 are connected, the lens holder 3 is suspended inside the bottle body 2. The lens holder 3 includes a connecting part 31 and a clamping part 32. One end of the connecting part 31 is detachably connected to the inside of the bottle cap 1, and the other end is connected to the clamping part 32. The clamping part 32 is provided with a slot 321 and a pair of hooks 322. The slot 321 is used to accommodate the intraocular lens 4; the pair of hooks 322 are provided on both sides of the slot 321 to facilitate the confinement of the intraocular lens 4 within the slot 321.
[0039] The working principle of this embodiment is as follows: The artificial lens 4 is placed in the slot 321, that is, the slot 321 is used to accommodate the artificial lens 4. The artificial lens 4 is limited by the hooks 322 on both sides of the clamping part 32, so that the artificial lens 4 cannot be detached from the slot 321, thus preventing the artificial lens from falling into the bottle body 2 during transportation.
[0040] The beneficial effects of this embodiment are: by using the slot 321 and the hook 322 together, the artificial lens 4 can be fixed on the lens holder 3, ensuring that it is stored stably within the packaging structure.
[0041] Example 2
[0042] like Figure 4-7 As shown, Embodiment 2 of a packaging structure for an intraocular lens differs from Embodiment 1 mainly in that:
[0043] The maximum distance between the two hooks 322 and the main body diameter D1 of the artificial lens 4 (e.g.) Figure 6 (As shown) are equal.
[0044] The maximum vertical distance H between the bottom of the slot 321 and the hook 322 (e.g.) Figure 5 (As shown) less than the straddle height h1 of the intraocular lens 4 (e.g.) Figure 7 As shown), and greater than the vertical distance h2 between the cut surface of the intraocular lens 4 and the end face of the optical body of the intraocular lens 4 (as shown). Figure 7 As shown), Figure 6-7 As shown, the cross-section is the protrusion of the artificial lens 4 in the direction of the main body diameter D1.
[0045] The surface shape of the slot 321 matches the surface shape of the support portion 41 of the artificial lens 4, for example, Figure 5 The surface of the card slot 321 is curved, which is consistent with... Figure 7 The curved surfaces of the central support portion 41 are matched with each other.
[0046] In addition, the clamping part 32 also includes a through hole 323, which communicates with the slot 321 along the axial direction of the slot 321. Figure 5 The Z-direction is indicated in the diagram, and the diameter of the through-hole 323 is smaller than the diameter D2 of the optical body of the artificial lens 4 (e.g., Figure 6 (As shown).
[0047] The clamping part 32 also includes a clamping opening 324, which is located along the radial R of the slot 321 (e.g., Figure 4 (As shown) is connected to the card slot 321.
[0048] The working principle of this embodiment is as follows: Since the distance between the inner walls of the two hooks 322 is equal to the diameter D1 of the main body of the intraocular lens 4, when the intraocular lens 4 is placed in the slot 321, the movement space of the intraocular lens 4 between the two hooks 322 is restricted. Furthermore, since the hooks 322 limit the cross-section of the intraocular lens 4, the intraocular lens 4 has a certain amount of movement space in the axial direction Z of the slot 321. This prevents the intraocular lens 4 from being tightly fitted to the slot 321 when stored in the packaging structure containing preservation fluid, and also facilitates the use of clamping tools to store or remove the intraocular lens 4 from the packaging structure without damage. In clinical use, when it is necessary to remove the intraocular lens 4 from the lens holder 3, the intraocular lens 4 can be pulled out from the slot 321 by clamping the loops of the intraocular lens 4 with tweezers or other clamps. Meanwhile, a through hole 323 is provided so that the artificial lens 4 can fully contact the preservation solution in the bottle body 2 when the cap 1 is connected to the bottle body 2.
[0049] The beneficial effects of this embodiment are as follows: By designing the distance between the two hooks 322, the range of the distance between the bottom of the slot 321 and the hooks 322, and the shape of the slot 321, the intraocular lens 4 can be better secured on the lens holder 3, while avoiding damage to the intraocular lens 4. Furthermore, by designing the clamping opening 324, the intraocular lens 4 can be easily clamped from the lens holder 3, improving the ease of clamping. Simultaneously, by providing the through hole 323, it is ensured that the intraocular lens 4 can be fully immersed in the preservation solution.
[0050] The remaining technical features and working principles of this embodiment are the same as those of Embodiment 1.
[0051] Example 3
[0052] like Figure 1 , 8 As shown, Example 3 of a packaging structure for intraocular lenses differs from Example 2 in that, based on Example 1, the main difference is:
[0053] The bottle cap 1 has a connector 11 inside, which is detachably connected to the crystal holder 31.
[0054] The total length of the crystal holder 3 is between 2 / 3 and 5 / 6 of the total length of the bottle body 2.
[0055] The working principle of this embodiment is as follows: When assembling the bottle cap 1 and the crystal holder 3, the connecting part 11 located inside the bottle cap 1 is connected to the connecting part 31 of the crystal holder 3 to complete the assembly.
[0056] In practical applications, to ensure the safety of the product during the sterilization process, it is optimal to fill the bottle 2 with the preservation solution to 75% of the total volume of the bottle. Therefore, the total length of the lens holder 3 designed in this embodiment can ensure that the artificial lens 4 can be fully immersed in the preservation solution in the bottle 2.
[0057] The beneficial effects of this embodiment are as follows: By precisely controlling the length of the lens holder 3, it is ensured that the intraocular lens 4 can be fully immersed in the preservation solution inside the bottle 2. The detachable design of the lens holder 3 and the bottle cap 1 ensures that every component of the packaging structure (bottle cap 1, bottle 2, and lens holder 3) is fully sterilized and disinfected before use, thus improving the safety of intraocular lens preservation.
[0058] The remaining technical features and working principles of this embodiment are the same as those of Embodiment 1.
