Description

Technical Field

[0001] This invention relates to the field of reagent kit technology, and more specifically to a reagent kit for serum detection. Background Technology

[0002] With the continuous advancement of the biomedical field, rapid detection methods based on specific target molecules have gradually become a research hotspot. For example, convenient and efficient reagent kits have emerged, becoming important tools for screening and diagnosing many diseases. Reagent kits are typically designed using antibody-antigen reaction principles or other molecular recognition technologies, combined with chemical or biosensor technologies, to achieve efficient, specific identification and quantitative detection of target substances.

[0003] The patent (publication number: CN204214872U) discloses an ELISA kit, including a box body, and an enzyme-labeled plate, standard tubes, antibody tubes, washing solution bottle, diluent bottle and substrate bottle inside the box body. The enzyme-labeled plate includes a plate body and wells on the plate body. The bottom of the wells is coated with capture antibodies, and a filter cartridge is inserted into the upper opening. The filter cartridge includes a filter cap and a filter membrane. The filter cap has membrane pores, and the membrane pores contain the filter membrane.

[0004] ELISA kits (Enzyme-Linked Immunosorbent Assay kits) are typically classified as serum assay kits. ELISA is a commonly used biochemical analysis method widely applied to the detection of specific antigens or antibodies in serum samples. Using ELISA, certain biomarkers in serum can be quantitatively or qualitatively analyzed, such as bacterial and viral infection markers, hormones, antibodies, and enzymes. Currently, the commonly used ELISA kit is the one described in the aforementioned application. During storage, ELISA kits are prone to accidental inversion by staff. If the reagent bottles are inverted, air bubbles or precipitates may form, affecting the accuracy of the experimental results. This necessitates extending the settling time before use, impacting detection efficiency. This is especially true for enzyme-labeled or antibody reagents, which are easily affected by temperature changes or uneven stirring; therefore, settling is necessary to ensure their activity. Meanwhile, existing ELISA kits require highly skilled personnel to use them, who need to be familiar with the specific operating procedures and steps, especially the number of microplates used, which is easy to get confused. Furthermore, the microplates are stored in separate sealed bags, making them difficult to access. Moreover, existing ELISA kits are disposable and can only hold one type of reagent. When performing multiple types of tests, different types of kits need to be carried separately, and the number of microplates required for each test needs to be clearly identified, which is very easy to cause confusion. Summary of the Invention

[0005] The purpose of this invention is to provide a reagent kit for serum detection in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A serum detection kit includes a modular base box and an enzyme-labeled plate. The outer side of the modular base box is tightly fitted with a lid. The interior of the modular base box has a storage cavity for storing the enzyme-labeled plate. A top plate is slidably connected to the interior of the storage cavity. A top spring is provided between the top plate and the inner wall of the storage cavity. A pull plate is inserted into the outlet of the storage cavity, and the pull plate can bring out the enzyme-labeled plate without restriction.

[0008] The top of the module base box has two sets of ball grooves. The bottom of the ball grooves is equipped with airbags. A spherical outer frame is tightly inserted into the inside of the ball grooves. Rollers are provided on the inner wall of the spherical outer frame. A storage ball box for storing test reagents is inserted into the inside of the spherical outer frame. A counterweight is provided at the bottom of the storage ball box. The counterweight ensures that the center of gravity of the storage ball box is always at the bottom.

[0009] The module's bottom box has a sliding cavity inside, which is connected to the storage cavity. Two sets of sliders are slidably connected inside the sliding cavity. A transmission air cylinder is fixedly installed on the top of the slider, and the transmission air cylinder is connected to an air bladder on the same side. A baffle is fixedly installed on the top of the telescopic end of the transmission air cylinder, and a compression spring is provided on the top of the baffle. The baffle restricts the outward movement of the enzyme-labeled plate between itself and the top plate.

[0010] Furthermore, the top of the pull-out plate is hinged with several swing claws, which are arranged in a linear row and the enzyme-labeled plates are staggered. The side of the swing claws closest to the storage cavity is inclined. Several limiting spring strips are fixedly installed on the top of the pull-out plate. The limiting spring strips are located on the side of the swing claws closest to the storage cavity. A torsion spring is provided at the hinge of the swing claws.

[0011] Furthermore, a sealing plate is provided at the front end of the pull-out plate, and a handle groove is provided on the outer side of the sealing plate. A handle is hinged to the top of the handle groove. A sliding hole is provided at the top of the sealing plate, and a locking block is slidably connected inside the sliding hole. A retaining spring is provided between the locking block and the inner wall of the sliding hole. The handle is connected to the locking block by a pull rope. The locking block is designed with an inclination on the side near the storage cavity. A locking groove is provided at the top of the inner side of the storage cavity. When the sealing plate completely seals the storage cavity, the locking block is inserted into the locking groove.

[0012] Furthermore, a tray is provided at the bottom of the storage cavity, and the length of the tray and the pull-out plate is the same as the length of the storage cavity. Several arc grooves are provided on the top of both the tray and the pull-out plate.

[0013] Furthermore, adjusting bolts are rotatably installed at both ends of the sliding cavity, and a nut sleeve is provided on the outer side of the slider. The nut sleeve is threadedly connected to the adjusting bolt, and the adjusting bolt is a countersunk bolt.

[0014] Furthermore, the spherical outer frame is composed of a support base and several external claw rods. The external claw rods are distributed in a ring on the support base. Rollers are provided on both the external claw rods and the support base. An elastic connecting rod is provided in the middle of the external claw rod. The central angle of the ball groove is 200-220 degrees. When the spherical outer frame is fully inserted into the ball groove, the upper half of the elastic connecting rod is located at the top edge of the ball groove. Several grooves are formed in a ring on the inner wall of the ball groove, and the external claw rods are inserted into the grooves.

[0015] Furthermore, the top of the outer claw bar is provided with a hook portion.

[0016] Furthermore, the ball storage box consists of two semi-circular boxes connected by threads. The interior of each semi-circular box is equipped with a sponge liner, and the outer side of the sponge liner is provided with a medicine storage slot. The counterweight iron block is located at the bottom of the inner side of the semi-circular box.

[0017] Furthermore, at least two sets of module base boxes are provided, with adjacent module base boxes glued together, and the box cover is adapted to the parallel module base boxes.

[0018] Furthermore, a film is stored on the inner top of the lid.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. In this invention, a spherical outer frame is inserted into a spherical groove, and a storage box is inserted into the spherical outer frame. A roller is provided between the spherical outer frame and the storage box. The storage box contains a counterweight iron block. No matter how the reagent kit is turned over, the storage box always keeps the reagent opening facing upward, thus improving storage stability.

[0021] 2. This invention adopts a modular design, using a storage box to independently store different types of test reagents. Combined with the use of baffles and ELISA plates, after taking out the corresponding test reagent, the pull-out plate can bring out the corresponding number of ELISA plates, improving detection efficiency. In the process of multiple types of detection, it is not easy to cause confusion in the number of ELISA plates used, making detection convenient.

[0022] 3. This invention can combine modular boxes according to actual usage needs to achieve customization for different customer requirements, and the entire reagent kit can be reused. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1, as Figures 1-7 As shown, a serum detection kit includes a module base box 1 and an enzyme-labeled plate 4. A box cover 2 is tightly fitted to the outside of the module base box 1. A storage cavity 14 for storing the enzyme-labeled plate 4 is opened inside the module base box 1. A top plate 16 is slidably connected inside the storage cavity 14. A top spring 17 is provided between the top plate 16 and the inner wall of the storage cavity 14. A pull plate 5 is inserted into the outlet of the storage cavity 14. The pull plate 5 can bring out the enzyme-labeled plate 4 without restriction.

[0033] The top of the module base box 1 is provided with two sets of ball grooves 11. An air bag 13 is provided at the bottom of the ball groove 11. A spherical outer frame 6 is tightly inserted inside the ball groove 11. Rollers 62 are provided on the inner wall of the spherical outer frame 6. A storage ball box 7 for storing test reagents is inserted inside the spherical outer frame 6. A counterweight iron block 73 is provided at the bottom of the storage ball box 7. The counterweight iron block 73 ensures that the center of gravity of the storage ball box 7 is always located at the bottom.

[0034] The module base box 1 has an internal sliding cavity 18, which is connected to the storage cavity 14. Two sets of sliders 3 are slidably connected inside the sliding cavity 18. A transmission air cylinder 31 is fixedly installed on the top of each slider 3, and the transmission air cylinder 31 is connected to an air bag 13 on the same side. A baffle 32 is fixedly installed on the top of the telescopic end of the transmission air cylinder 31, and a compression spring 33 is provided at the top of the baffle 32. The baffle 32 restricts the outward movement of the enzyme-labeled plate 4 between itself and the top plate 16. A covering film is stored inside the top of the box lid 2.

[0035] In use, open the lid 2, remove the film from the lid 2 for later use, and then place the desired storage sphere 7 and spherical outer frame 6. The air bladder 13 is not compressed, and the air bladder 13 inflates. The internal air pressure of the transmission air cylinder 31 connected to it decreases, and the compression spring 33 pushes the corresponding baffle 32 down. The baffle 32 blocks the corresponding enzyme-labeled plate 4, and the baffle 32 restricts the enzyme-labeled plate 4 between it and the top plate 16 from moving outward. The enzyme-labeled plate 4 between the baffle 32 and the pull plate 5 can be pulled out with the pull plate 5. Therefore, the pull plate 5 is removed, and the enzyme-labeled plate 4 is removed quantitatively at once. After removal, the pull plate 5 is pushed back into the storage cavity 14 to keep the remaining enzyme-labeled plates 4 sealed and stored. The operation is simple.

[0036] When performing the next type of test, the completed reagents are stored back in the storage box 7, and then placed into the ball slot 11 along with the spherical outer frame 6. The air bladder 13 is compressed, increasing the internal air pressure of the transmission air cylinder 31 connected to it. The transmission air cylinder 31 pushes the corresponding baffle 32 upward away from the ELISA plate 4. At this time, the top spring 17 pushes the top plate 16 to slide, and the top plate 16 pushes the remaining ELISA plate 4 towards the pull plate 5. Then, the other storage box 7 and the spherical outer frame 6 are removed, and the air bladder 13 is no longer compressed and inflates. When the internal air pressure of the transmission air cylinder 31 connected to it decreases, the compression spring 33 pushes the corresponding baffle 32 to descend. The baffle 32 blocks the corresponding enzyme-labeled plate 4. The baffle 32 restricts the outward movement of the enzyme-labeled plate 4 between it and the top plate 16. The enzyme-labeled plate 4 between the baffle 32 and the pull plate 5 can be pulled out with the pull plate 5. Since the positions of the corresponding baffle 32 are different, the number of enzyme-labeled plates 4 between the baffle 32 and the pull plate 5 is different, so that it can meet the detection requirements, quickly realize different types of detection, and is less prone to errors.

[0037] After all tests are completed, the ball storage boxes 7 are reset and the lid 2 is closed. The friction between the spherical outer frame 6 and the ball groove 11 is large and they are in close contact, so the spherical outer frame 6 will not rotate. However, due to the setting of the roller 62, the ball storage box 7 can rotate freely in the spherical outer frame 6. Therefore, no matter how the test box is flipped, the counterweight iron block 73 at the bottom of the ball storage box 7 always faces downwards, and the reagent opening in the ball storage box 7 always faces upwards, ensuring stable storage.

[0038] Example 2, based on the above examples, further includes a plurality of swing claws 51 hinged to the top of the pull-out plate 5. The swing claws 51 are arranged in a linear row, and the enzyme-labeled plates 4 are arranged in a staggered manner. The side of the swing claws 51 closest to the storage cavity 14 is designed to be inclined. A plurality of limiting spring strips 52 are fixedly installed on the top of the pull-out plate 5. The limiting spring strips 52 are located on the side of the swing claws 51 closest to the storage cavity 14. A torsion spring is provided at the hinge of the swing claws 51.

[0039] A sealing plate 53 is provided at the front end of the pull-out plate 5. A handle groove 54 is provided on the outer side of the sealing plate 53. A handle 55 is hinged to the inner top of the handle groove 54. A sliding hole is provided at the top of the sealing plate 53. A locking block 56 is slidably connected inside the sliding hole. A retaining spring 57 is provided between the locking block 56 and the inner wall of the sliding hole. The handle 55 is connected to the locking block 56 by a pull rope. The side of the locking block 56 near the storage cavity 14 is inclined. A slot 19 is provided at the inner top of the storage cavity 14. When the sealing plate 53 completely seals the storage cavity 14, the locking block 56 is inserted into the slot 19.

[0040] This embodiment provides a specific structure for the pull-out plate 5. By pulling the handle 55, the handle 55 drives the locking block 56 to slide down away from the locking slot 19 via the pull rope. At this time, the pull-out plate 5 is brought out by the handle 55. The pull-out plate 5, through the swing claws 51 on it, brings out the enzyme-labeled plate 4 between the baffle 32 and the sealing plate 53. It should be noted that the number of rows of swing claws 51 is greater than the number of enzyme-labeled plates 4, so different numbers of enzyme-labeled plates 4 can be brought out. Therefore, the enzyme-labeled plates 4 between the baffle 32 and the sealing plate 53 are not restricted. Therefore, under the blocking force of the limiting elastic bar 52, the corresponding claw 51 at this position cannot swing backward. The claw 51 can stably carry out the enzyme-labeled plate 4 between the baffle 32 and the sealing plate 53. However, the enzyme-labeled plate 4 between the baffle 32 and the top plate 16 is restricted by the baffle 32. Therefore, the claw 51 at this position will swing backward and bend the limiting elastic bar 52. The claw 51 will disengage from the blocked enzyme-labeled plate 4, so only the corresponding number of enzyme-labeled plates 4 can be taken out. Moreover, the position of the baffle 32 can be adjusted to remove the number of enzyme-labeled plates 4.

[0041] After removal, the pull plate 5 is pushed into the storage cavity 14. When the card block 56 approaches the edge of the storage cavity 14, it is pressed into the sliding hole under the action of the inclined surface. When the sealing plate 53 completely seals the storage cavity 14, the card spring 57 pushes the card block 56 into the card slot 19, realizing the resetting and sealing of the pull plate 5. When the used test reagent is reset, the corresponding baffle 32 moves away from the enzyme labeling plate 4, and the top spring 17 pushes the top plate 16 to slide. The top plate 16 pushes the remaining enzyme labeling plate 4 towards the pull plate 5. Since there is no restriction in front of the swing claw 51, the swing claw 51 will swing forward under the action of the enzyme labeling plate 4. It should be noted that the swing claw 51 is equipped with a torsion spring. The torsion spring has a small elastic force, which only makes the swing claw 51 swing to the vertical position. When the enzyme labeling plate 4 passes through the swing claw 51, the swing claw 51 swings to the vertical position under the action of the torsion spring and is located between adjacent enzyme labeling plates 4, which does not affect the automatic feeding of the enzyme labeling plate 4.

[0042] In embodiment three, based on the above embodiments, a tray 15 is provided at the bottom of the storage cavity 14. The length of the tray 15 and the pull-out plate 5 is the same as the length of the storage cavity 14. Several arc grooves are provided on the top of both the tray 15 and the pull-out plate 5. This design allows for more stable storage of the enzyme-labeled plate 4.

[0043] Example 4, based on the above examples, further includes adjusting bolts 35 rotatably installed at both ends of the sliding cavity 18, and a nut sleeve 34 provided on the outer side of the slider 3. The nut sleeve 34 is threadedly connected to the adjusting bolts 35. The adjusting bolts 35 are countersunk bolts, which do not affect the box cover 2 being fitted onto the module bottom box 1.

[0044] With this design, when the type of reagent in the storage box 7 needs to be changed, the required number of ELISA plates 4 also changes. In this case, rotating the adjusting bolt 35 causes the slider 3 to move through the nut sleeve 34 into the sliding cavity 18. The slider 3 then moves the baffle 32 to change position, thereby changing the number of ELISA plates 4 that can be retrieved at one time. Therefore, with this embodiment, the detection box of the present invention has a wider range of reusability, is not limited by reagent type, and can store any type of reagent, making it more convenient to use. Therefore, the material of the present invention can be low-cost plastic.

[0045] Example 5, based on the above examples, further includes a spherical outer frame 6 composed of a bottom support 61 and several outer claw rods 63. The several outer claw rods 63 are distributed in a ring on the bottom support 61. Rollers 62 are provided on both the outer claw rods 63 and the bottom support 61. An elastic connecting rod 64 is provided in the middle of the outer claw rods 63. The central angle of the ball groove 11 is 200-220 degrees. When the spherical outer frame 6 is fully inserted into the ball groove 11, the upper half of the elastic connecting rod 64 is located at the top edge of the ball groove 11. Several grooves 12 are provided in a ring on the inner wall of the ball groove 11. The outer claw rods 63 are inserted into the grooves 12. The grooves 12 can more effectively prevent the spherical outer frame 6 from rotating.

[0046] The top of the outer claw rod 63 is provided with a hook portion 65.

[0047] With the design of this embodiment, when it is necessary to take out the storage box 7, the spherical outer frame 6 is pulled upward by the hook part 65. At this time, under the action of the top edge of the ball groove 11, the elastic connecting rod 64 bends inward, and the radius of the spherical outer frame 6 at this position decreases, so that it can just disengage from the ball groove 11. When inserted, since the central angle of the ball groove 11 is 200-220 degrees, the spherical outer frame 6 will not disengage from the ball groove 11. The insertion is tight, ensuring that the spherical outer frame 6 will not disengage from the ball groove 11 during transportation, making storage and retrieval convenient.

[0048] Example 6, based on the above examples, further includes a ball storage box 7 consisting of two semi-circular boxes 71 connected by threads. The interior of each semi-circular box 71 is provided with a sponge liner 72, and the outer side of the sponge liner 72 is provided with a medicine storage slot. A counterweight iron block 73 is provided at the bottom of the inner side of the semi-circular box 71.

[0049] The ball storage box 7 can be quickly assembled and disassembled through the threaded connection, and the sponge inner liner 72 can stably store reagents.

[0050] Example 7, based on the above examples, further includes at least two sets of module base boxes 1, with adjacent module base boxes 1 bonded together, and the cover 2 adapted to the parallel module base boxes 1.

[0051] This invention allows for the production of reagent kits with multiple modular base boxes 1 arranged side-by-side to better meet customer needs. Furthermore, due to the design of the ball storage box 7, customers can choose not to use the corresponding lid 2. This way, when expansion is needed later, only the modular base box 1 needs to be purchased, eliminating the need to separately select the corresponding lid 2. The lid 2 has a simple manufacturing process, no complex structure, and relatively low production cost per specification. Moreover, this invention can also use half of the modular base box 1, that is, only one ball groove 11 is required, making it flexible and highly scalable.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
