Technical Field
[0001] This utility model relates to the technical field of cholesterol detection kits, specifically a small and dense low-density lipoprotein cholesterol detection kit. Background Technology
[0002] Low-density lipoprotein (LDL) is heterogeneous, consisting of a series of particles of varying sizes, densities, and chemical compositions. Currently, the main methods for measuring small and dense low-density lipoprotein cholesterol include nuclear magnetic resonance spectroscopy, molecular sieve chromatography, electron microscopy, dynamic light scattering, and microfluidic chip capillary electrophoresis. Detection of lipoprotein cholesterol requires the use of test kits, test strips, and reagent bottles for proper storage.
[0003] Chinese Utility Model Patent Publication No. CN218318136U discloses a small and dense low-density lipoprotein cholesterol (LDL-C) test kit. The kit's instruction manual discloses a cover and sealing assembly that cooperate with each other on the box body. Samples and reagents are sequentially dripped into each sample compartment. The cover is placed on the box body, and one end of the sealing assembly is inserted into the sample compartment, preventing samples from mixing when the box is removed, thus improving the device's practicality. However, this small and dense LDL-C test kit makes it inconvenient to separately store reagents, test strips, and test tubes, leading to mixed storage and potential contamination. Summary of the Invention
[0004] The technical problem to be solved by this invention is to provide a small and dense low-density lipoprotein cholesterol detection kit, which can effectively solve the problem in the prior art that it is not convenient to classify and store reagents, test strips and test tubes, resulting in mixed storage of reagents, test strips and test tubes, which makes them prone to contamination.
[0005] The technical solution adopted by this utility model is: a small and dense low-density lipoprotein cholesterol test kit, including a storage box, a first placement component and a second placement component. The storage box has at least two storage slots. The first placement component and the second placement component are placed in the storage box through the storage slots. A hinge is provided at the outer edge of the storage box. A top cover is provided at the other end of the hinge away from the storage box.
[0006] The first placement component includes a placement rack with a placement slot, and the placement rack has retrieval slots on both sides near the placement slot. A bracket one and a bracket two are engaged in the placement slot.
[0007] The second placement component includes a base plate, a support column, and a top plate. A limiting groove is formed through the top plate, and a cover plate is engaged in the limiting groove. A reagent tube is inserted into the cover plate. A limiting block is fixedly installed on one end of the base plate near the top plate, and the reagent tube is in contact with the limiting block.
[0008] Preferably, the limiting block, cover plate and reagent tube are provided in at least five identical sets, wherein the diameter of three sets of the limiting block, cover plate and reagent tube is larger than the diameter of the other two sets of the limiting block, cover plate and reagent tube.
[0009] Through the above technical solution, three sets of large-diameter limiting blocks are adapted to conventional reagent tubes, and two sets of small-diameter limiting blocks are adapted to micro-reagent tubes, which meets the classification and storage requirements in the detection of small and dense low-density lipoproteins and improves its practicality.
[0010] Preferably, a front handle is fixedly installed at the end of the storage box away from the hinge, and a top handle is rotatably installed at the end of the top cover away from the storage box.
[0011] Through the above technical solution, the front handle and the top handle of the storage box form a two-way grip structure. The front handle is convenient for horizontal handling, and the top handle is suitable for vertical lifting. The design of the two handles makes it easier for users to pick up the items.
[0012] Preferably, slot 1 is provided through the four corners of the base plate from top to bottom, slot 2 is provided through the four corners of the top plate from top to bottom, and positioning posts are fixedly installed inside the storage box, with the positioning posts being plugged into slot 1 and slot 2.
[0013] Through the above technical solution, the slot one of the bottom plate and the slot two of the top plate are inserted into the positioning post to form a detachable three-dimensional placement structure, which facilitates the quick placement of the second placement component into the storage box, facilitates displacement, and also facilitates the retrieval of the second placement component.
[0014] Preferably, the storage box is provided with a latch at the end away from the hinge, and a locking hook is fixedly installed at the end of the top cover near the latch, and the latch and the locking hook are fastened together.
[0015] The above technical solution forms a locking structure by connecting the latch and the hook, which prevents the top cover from being accidentally opened and causing reagent contamination. At the same time, it is easy to accidentally open during movement, which could cause the reagent kit and test tubes to fall out.
[0016] Preferably, the first bracket is provided with test strips, and the second bracket is provided with a test tube rack.
[0017] With the above technical solution, tray one stores the test strips, and tray two holds the test tubes, forming a partitioned storage to prevent the test strips from getting damp and becoming ineffective.
[0018] Preferably, a support base is fixedly installed at the end of the storage box and the top cover near the hinge, and the end of the support base away from the storage box and the top cover has anti-slip texture, and the end of the storage box near the hinge has a slot.
[0019] With the above technical solution, the support base is fixed on both sides of the hinge. When the top cover is opened, it can support the top cover to maintain the tilt angle and prevent the top cover from colliding with the storage box after it is fully opened. The anti-slip texture increases the friction between the support base and the table surface and prevents the storage box from sliding during operation.
[0020] Compared with the prior art, this utility model provides a small and dense low-density lipoprotein cholesterol detection kit, which has the following beneficial effects:
[0021] 1. This small and compact low-density lipoprotein cholesterol test kit, through the design of the first and second placement components, can facilitate the classified storage of reagents, test strips and test tubes, avoiding the problem of mixed storage of reagents, test strips and test tubes, which is prone to contamination, and can increase its storage capacity, thereby improving its overall practicality.
[0022] 2. This small and compact low-density lipoprotein cholesterol test kit has a support base fixed on both sides of the hinge. When the top cover is opened, it can support the top cover to maintain the tilt angle and prevent the top cover from colliding with the storage box after it is fully opened. The anti-slip texture increases the friction between the support base and the table surface to prevent the storage box from sliding during operation. The front handle of the storage box and the top handle of the top cover form a two-way grip structure. The design of the two handles makes it easier for users to pick up the kit.

[0031] 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.
[0032] Example 1: As Figure 1-7 As shown, the present invention provides a small and dense low-density lipoprotein cholesterol test kit, including a storage box 1, a first placement component 5 and a second placement component 6. The storage box 1 has at least two storage slots 4. The first placement component 5 and the second placement component 6 are placed in the storage box 1 through the storage slots 4. A hinge 7 is provided at the outer edge of the storage box 1, and a top cover 8 is provided at the other end of the hinge 7 away from the storage box 1.
[0033] The first placement component 5 includes a placement rack 501 with a placement slot 502, and two sides of the placement rack 501 near the placement slot 502 with retrieval slots 503. A bracket 1 504 and a bracket 2 506 are engaged in the placement slot 502.
[0034] The second placement component 6 includes a base plate 601, a support column 602, and a top plate 605. A limiting groove 607 is formed through the top plate 605. A cover plate 608 is snapped into the limiting groove 607. A reagent tube 609 is inserted into the cover plate 608. A limiting block 603 is fixedly installed on one end of the base plate 601 near the top plate 605. The reagent tube 609 is in contact with the limiting block 603.
[0035] Specifically, there are at least five identical sets of limiting blocks 603, cover plates 608, and reagent tubes 609. Among them, the diameters of three sets of limiting blocks 603, cover plates 608, and reagent tubes 609 are larger than the diameters of the other two sets of limiting blocks 603, cover plates 608, and reagent tubes 609. The advantage is that the three sets of large-diameter limiting blocks 603 are adapted to conventional reagent tubes 609, and the two sets of small-diameter limiting blocks 603 are adapted to micro-reagent tubes 609, which meets the classification and storage requirements in the detection of small and dense low-density lipoproteins and improves its practicality.
[0036] Specifically, a front handle 2 is fixedly installed at the end of the storage box 1 away from the hinge 7, and a top handle 9 is rotatably installed at the end of the top cover 8 away from the storage box 1. The advantage is that the front handle 2 of the storage box 1 and the top handle 9 of the top cover 8 form a two-way grip structure. The front handle 2 is convenient for horizontal handling, and the top handle 9 is suitable for vertical lifting. The design of the two handles makes it easier for users to take things out.
[0037] Specifically, slot 1 604 is provided through the four corners of the base plate 601 from top to bottom, and slot 2 606 is provided through the four corners of the top plate 605 from top to bottom. Positioning post 14 is fixedly installed inside the storage box 1. The positioning post 14 is plugged into slot 1 604 and slot 2 606. The advantage is that the slot 1 604 of the base plate 601 and slot 2 606 of the top plate 605 are plugged into the positioning post 14 to form a detachable three-dimensional placement structure, which makes it easy to quickly place the second placement component 6 into the storage box 1, facilitates displacement, and also makes it easy to retrieve the second placement component 6.
[0038] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.
[0039] Specifically, a latch 3 is provided at the end of the storage box 1 away from the hinge 7, and a hook 13 is fixedly installed at the end of the top cover 8 near the latch 3. The latch 3 and the hook 13 are fastened together. The advantage is that the fastening structure of the latch 3 and the hook 13 forms a locking structure, which prevents the top cover 8 from being opened accidentally and causing reagent contamination. At the same time, it is easy to cause accidental opening when moving, which may cause the reagent kit and test tubes to fall out.
[0040] Specifically, test strips 505 are placed on bracket 1 504, and test tube racks 507 are placed on bracket 2 506. The advantage is that the test strips 505 are stored on bracket 1 504, and the test tube racks 507 on bracket 2 506 fix the reagent tubes 609, forming a partitioned storage to prevent the test strips 505 from getting damp and becoming ineffective.
[0041] Specifically, a support base 10 is fixedly installed on the storage box 1 and the top cover 8 near the hinge 7. The end of the support base 10 away from the storage box 1 and the top cover 8 is provided with anti-slip texture 11. The end of the storage box 1 near the hinge 7 is provided with a slot 12. The advantage is that the support base 10 is fixed on both sides of the hinge 7, and can support the top cover 8 to maintain its tilt angle when the top cover 8 is opened, so as to avoid the top cover 8 from colliding with the storage box 1 after it is fully opened. The anti-slip texture 11 increases the friction between the support base 10 and the table surface, preventing the storage box 1 from sliding during operation.
[0042] Working principle: During use, three sets of large-diameter limiting blocks 603 are adapted to conventional reagent tubes 609, and two sets of small-diameter limiting blocks 603 are adapted to micro-reagent tubes 609, meeting the classification and storage needs in the detection of small and dense low-density lipoproteins and improving its practicality. The front handle 2 of the storage box 1 and the top handle 9 of the top cover 8 form a two-way grip structure. The front handle 2 is convenient for horizontal carrying, and the top handle 9 is suitable for vertical lifting. The design of the two handles makes it easier for users to pick up the tubes. The slot 1 604 of the bottom plate 601 and the slot 2 606 of the top plate 605 are inserted into the positioning post 14 to form a detachable three-dimensional placement structure, which facilitates the quick placement of the second placement component 6 into the storage box 1, and facilitates the release of the product. The top cover 8 is designed to facilitate displacement and easy access to the second placement component 6. The locking structure of the latch 3 and the hook 13 forms a locking structure to prevent accidental opening of the top cover 8 and resulting reagent contamination. At the same time, it is easy to cause accidental opening during movement, which could lead to the scattering of reagent kits and test tubes. The first bracket 504 stores the test strip 505, and the second bracket 506's test tube rack 507 fixes the reagent tubes 609, forming a partitioned storage to prevent the test strip 505 from becoming damp and ineffective. The support base 10 is fixed on both sides of the hinge 7 and can support the top cover 8 to maintain its tilt angle when the top cover 8 is opened, preventing the top cover 8 from colliding with the storage box 1 after it is fully opened. The anti-slip texture 11 increases the friction between the support base 10 and the table surface to prevent the storage box 1 from sliding during operation.
