Technical Field
[0001] This utility model relates to the field of reagent kit technology, specifically a low-density lipoprotein cholesterol detection kit. Background Technology
[0002] Low-density lipoproteins (LDL-C) exhibit heterogeneity, consisting of a series of particles varying in size, density, and chemical composition. Current methods for measuring small, dense LDL-C primarily include nuclear magnetic resonance spectroscopy, molecular sieve chromatography, electron microscopy, dynamic light scattering, and microfluidic chip capillary electrophoresis. Lipoprotein cholesterol testing requires a detection kit, and the collection box divides the sample into multiple equal portions during testing.
[0003] Chinese Utility Model Patent Publication No. CN220340236U discloses a low-density lipoprotein cholesterol (LDL-C) test kit. The kit's specifications disclose that aluminum foil seals the test chamber, preventing contamination. A cutting line allows for easy removal of the aluminum foil. A reagent bottle storage slot and a dropper storage slot store the reagent bottles and droppers, respectively. Sample solutions can be drawn from the reagent bottles using the droppers. However, while the kit allows for the storage of reagent bottles and droppers, it is not convenient for storing bottles of different sizes, potentially leading to low storage capacity. Furthermore, the lack of a flip-top design necessitates frequent full-cap opening, causing internal temperature fluctuations and affecting subsequent normal use. Summary of the Invention

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1: As Figure 1-6 As shown, the present invention provides a low-density lipoprotein cholesterol test kit, including a storage box 1, anti-collision sleeves 2 fixedly installed at the four corners of the storage box 1, at least two slots 3 opened on the inner edge of the storage box 1, insert plates 5 inserted into the storage box 1 through the slots 3, storage rack 7 and storage rack 9 arranged inside the storage box 1, storage slot 8 and storage slot 10 through the storage rack 7 and storage rack 9, and flip cover 11 and flip cover 25 rotatably installed on the outer edge of the storage box 1, the flip cover 11 and flip cover 25 being located above the storage rack 7 and storage rack 29.
[0030] Specifically, a groove 4 is provided on the inner edge of the storage box 1, and an extension plate 6 is fixedly installed on the upper edge of the insert plate 5. The extension plate 6 overlaps with the groove 4. The advantage is that the insert plate 5 can be inserted into the slot 3 through the cooperation of the extension plate 6 and the groove 4, which can then separate the internal space of the storage box 1, avoid collisions between reagent bottles of different sizes during transportation, and facilitate the classified storage of different components such as buffer solutions and antibody reagents required for testing.
[0031] Specifically, there are multiple identical storage slots 8 and 10, which are equidistantly distributed. The diameter of storage slot 10 is larger than that of storage slot 8. The advantage is that the equidistantly distributed storage slots 8 and the larger diameter storage slots 10 can be adapted to small-dose reagent bottles and large-dose reagent bottles respectively, realizing modular storage of test kits and facilitating quick access by users.
[0032] Specifically, hinge 12 and hinge 20 are provided on the outer edge of storage box 1. Hinge 12 is provided with flip cover 11 at the end away from storage box 1, and hinge 20 is provided with flip cover 25 at the end away from storage box 1. The advantage is that hinge 12 and hinge 20 connect flip cover 11 and flip cover 25 to storage box 1 respectively, forming a double flip cover structure. Storage rack 1 7 and storage rack 2 9 can be opened separately, which makes it convenient for operators to take out reagents from specific areas as needed and avoids internal temperature fluctuations caused by frequent full opening of the flip cover. It is especially suitable for the protective storage of temperature-sensitive reagents.
[0033] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.
[0034] Specifically, latch 18 and latch 2 19 are fixedly installed on the outer edge of storage box 1. Snap-fit blocks 14 and 2 17 are fixedly installed on the ends of flip cover 11 and flip cover 2 15 near latch 18 and latch 2 19. The advantage is that the cooperation between latch 18, latch 2 19 and snap-fit blocks 14 and 2 17 can form a locking structure, which can fix flip cover 11 and flip cover 2 15.
[0035] Specifically, the second flip cover 15 abuts against the extension plate 6. The side of the first flip cover 11 and the second flip cover 15 near the storage box 1 is fixedly equipped with the first protrusion 13 and the second protrusion 16. The first protrusion 13 and the second protrusion 16 correspond one-to-one with the first storage slot 8 and the second storage slot 10. The advantage is that the first protrusion 13 and the second protrusion 16 on the inside of the flip cover correspond one-to-one with the first storage slot 8 and the second storage slot 10. When the flip cover is closed, the protrusions can press the bottle cap of the reagent bottle to form an elastic buffer fixation, which can prevent the reagent bottle from shaking up and down during transportation.
[0036] Specifically, there are two identical insert plates 5, extension plates 6, flip covers 11, hinges 12, protrusions 13, snap-fit blocks 14, and latches 18. The two insert plates 5, extension plates 6, flip covers 11, hinges 12, protrusions 13, snap-fit blocks 14, and latches 18 are symmetrically distributed about the center line of the storage box 1. The advantage is that the two sets of symmetrically distributed insert plates 5, flip covers 11, and other components can balance the internal load of the storage box 1, prevent the center of gravity from shifting due to reagents stored on one side, and at the same time increase its storage capacity and improve its practicality.
[0037] Working principle: During use, the extension plate 6 cooperates with the groove 4 to insert the insert plate 5 into the slot 3, which then separates the internal space of the storage box 1, preventing reagent bottles of different sizes from colliding during transportation. This also facilitates the classified storage of different components such as buffer solutions and antibody reagents required for testing. The equidistantly distributed storage slots 1-8 and 2-10 (with a larger diameter) can accommodate small-dose and large-dose reagent bottles respectively, achieving modular storage of the test kits and allowing for quick retrieval by users. Hinges 1-12 and 2-20 connect the flip-top 1-11, flip-top 2-15, and storage box 1 respectively, forming a double-flip-top structure. Storage racks 1-7 and 2-9 can be opened separately, allowing operators to retrieve specific components as needed. This storage box is designed for regional reagent storage, avoiding internal temperature fluctuations caused by frequent full opening of the lid. It is especially suitable for the protective storage of temperature-sensitive reagents. The locking mechanism of latches 18 and 19, along with locking blocks 14 and 17, forms a locking structure that secures lids 11 and 15. The protrusions 13 and 16 on the inside of the lid correspond one-to-one with storage slots 8 and 10. When the lid is closed, the protrusions press against the reagent bottle cap, forming an elastic buffer and preventing the reagent bottle from shaking during transportation. The two sets of symmetrically distributed inserts 5 and lids 11 balance the internal load of the storage box 1, preventing the center of gravity from shifting due to reagent storage on one side. This also increases its storage capacity and practicality.
