Description

Technical Field

[0001] The utility model relates to the technical field of kits, in particular to an immunoassay kit. Background Art

[0002] Immunology has a long history. Ancient China used smallpox vaccination to prevent smallpox, marking humanity's earliest attempt to utilize immune principles to prevent disease. Later, Western medical scientists also gradually began to study immune phenomena. For example, the development of microbiology in the late 19th century laid the foundation for the formation of immunology, with discoveries such as leukocyte phagocytosis, diphtheria antitoxin, and complement. These discoveries supported the development of humoral and cellular immunity. Since the mid-20th century, immunological theory has continued to evolve and improve. For example, the theory of clonal selection has been proposed, explaining most immune phenomena and providing theoretical support for the further development of immunology. Simultaneously, research on immune cells has deepened, with discoveries such as B cells and T cells and their subsets, the synergistic effects between immune cells, and major histocompatibility complex restriction, furthering our understanding of the immune system.

[0003] In a laboratory, there are many reagent tubes containing test samples. In order to prevent the reagent tubes from being contaminated by being exposed to the air for a long time and to prevent the reagent tubes from being damaged by bumps, the reagent tubes are usually placed in a test kit to achieve the purpose of protecting the reagent tubes. Most existing test kits are composed of a box body, a reagent tube holder and a box cover. In the process of taking the reagent tubes, it is necessary to open the box cover to expose all the reagent tubes in the box body. This way of taking increases the risk of the reagent tubes being contaminated and reduces the protective effect of the reagent tubes. At the same time, the simultaneous presentation of multiple groups of reagent tubes is likely to cause interference to the experimenter, thereby causing the experimenter to take the reagent tubes incorrectly and making it inconvenient to take the reagent tubes. In addition, the existing reagent tube holder does not have a clamping function. When the reagent tubes are placed in the reagent tube holder, the reagent tubes can still move relative to the reagent tube holder. When the box body is shaken by external force, the reagent tubes are likely to collide with the reagent tube holder or fall off from the reagent tube holder.

[0004] Therefore, there is an urgent need for a technology to replace the existing method in which the reagent tube in the reagent test kit can still move relative to the reagent tube fixing seat, so as to solve the problem of how to reduce the collision between the reagent tube and the reagent tube fixing seat and the problem of falling off from the reagent tube fixing seat. Summary of the Invention

[0005] In view of this, the utility model proposes an immunoassay kit, which aims to solve the problem of how to reduce the collision between the reagent tube and the reagent tube fixing seat and the problem of the reagent tube falling off the reagent tube fixing seat.

[0036] See Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides an immunoassay kit, comprising:

[0037] The box body 100 has an accommodating cavity inside, and a through hole 120 is provided on the lower surface of the accommodating cavity;

[0038] The fixing frame 200 is arranged inside the accommodating cavity and fixedly connected to the inner side of the box body 100. The upper surface of the fixing frame 200 is provided with a placement cavity 230, and the placement cavity 230 is provided with a clamping device 240;

[0039] The push plate 300 is provided on the lower surface of the fixing frame 200. The push plate 300 is provided with a push rod 310 on the lower surface thereof. The push rod 310 corresponds to the shape of the through hole 120 and extends through the through hole 120 to the outside of the box body 100.

[0040] The cover plate 400 is disposed on the upper surface of the box body 100 .

[0041] Specifically, the accommodating cavity provides a larger internal space for placing the fixing frame 200 and the push plate 300 to meet different usage requirements; the setting of the through hole 120 facilitates the movement of the push rod 310, making the operation of the push plate 300 more convenient, and the movement of the push plate 300 can be controlled from the outside of the box body 100 by the push rod 310 to achieve specific functions; the placement cavity 230 and the clamping device 240 on the fixing frame 200 can stably fix the reagent tube placed therein, prevent the reagent tube from shaking or moving in the box body 100, and ensure the safety and stability of the items.

[0042] It can be understood that this structure can be applied to a variety of scenarios. It can be used to place and fix experimental samples in the laboratory. Specific operations can be performed through the push plate 300. The clamping device 240 can be customized or replaced according to different usage requirements, thereby improving the applicability of the box body 100. The overall structural design is reasonable, and the various components cooperate with each other, allowing users to easily operate and use it.

[0043] Specifically, in the immunoassay kit, a first slideway 110 is provided on the inner side of the box body 100 , and the first slideway 110 is triangular.

[0044] Specifically, the triangular first slideway 110 is more stable than slideways of other shapes and can guide the slider 430 to be better fixed.

[0045] See Figure 4 As shown, the immunoassay kit has a clamping device that passes through the fixing frame 200 . The clamping device is composed of two half rings. The clamping device is connected to the inner wall of the placement cavity 230 through a first spring 210 .

[0046] Specifically, during the immunoassay process, sample stability is crucial. The clamping device can firmly fix the sample reagent tube to prevent the sample from spilling or mixing due to shaking or collision during transportation. When transferring the test kit from one area of ​​the laboratory to another for different stages of testing, the clamped sample can remain stable even after bumps, ensuring the integrity of the sample and providing the prerequisite for subsequent accurate testing.

[0047] It is understandable that different types of sample reagent tubes may differ in shape, size, etc. The clamping device has a certain degree of adjustability and can adapt to sample reagent tubes of various specifications. Whether it is routine clinical testing or special sample testing in scientific research experiments, as long as some components of the clamping device are replaced or adjusted, different sample containers can be compatible, thereby improving the versatility and economy of the test kit.

[0048] Specifically, the outer side of the immunoassay kit is provided with a second slide 220 , which corresponds in shape to the first slide 110 . The slide formed by the first slide 110 and the second slide 220 is in perfect engagement with the slider 430 .

[0049] See Figure 5 and Figure 6 As shown, in the immunoassay kit, a second spring 320 is provided on the lower surface of the push plate 300, and the other end of the second spring 320 is connected to the bottom of the accommodating cavity for buffering and pulling the push plate 300 back to its original position.

[0050] Specifically, during the immunoassay process, the push plate 300 may be affected by various external forces. When the push plate 300 is pushed manually, since the operating force may be difficult to accurately control, the second spring 320 can play a buffering role. If there is no spring, excessive thrust may cause the push plate 300 to collide violently with the bottom of the reagent tube, thereby damaging the reagent tube in the test kit. The spring buffer can reduce the impact force and prevent the sample from leaking or being damaged.

[0051] Specifically, when taking the reagent tube, the cover 400 is opened to separate the slider 430 from the third slide 330 of the push plate 300, thereby releasing the fixation of the push plate 300. At this time, the box body 100 is pressed downward. Since the push rod 310 of the push plate 300 passes through the through hole 120 at the bottom of the box body 100 and contacts the supporting surface and cannot move downward, the box body 100 moves downward relative to the push plate 300, and the push plate 300 moves upward relatively. The buffer layer on its surface pushes the bottom of the reagent tube, so that the reagent tube is upwardly separated from the restraint of the clamping assembly 240 in the placement cavity 230 of the fixing frame 200. The reagent tube can be taken out when it is exposed to a sufficient length. After taking the tube, the pressure on the box body 100 is removed, and the push plate 300 is reset downward to its initial position under the action of the second spring 320.

[0052] It can be understood that after the push plate 300 completes a pushing operation, the second spring 320 can pull it back to its original position. When the same detection operation needs to be performed multiple times, this automatic reset function can facilitate the reuse of the test kit. In automated immunoassays, the push plate 300 automatically resets after a detection cycle, allowing the test kit to quickly enter the next detection cycle without manual intervention to manually restore the position of the push plate 300, thereby improving the efficiency and automation of the detection.

[0053] Specifically, in the immunoassay kit, a slider 430 is provided on the surface of the cover plate 400 . The slider 430 is triangular in shape and corresponds to the slideway formed by the box body 100 and the fixing frame 200 .

[0054] Specifically, in the immunoassay kit, a third slideway 330 is provided on the side of the push plate 300 . The shape of the third slideway 330 corresponds to the shape of the slider 430 , and is used to fix the push plate 300 to prevent the push plate 300 from moving upward under force.

[0055] Specifically, a third slideway 330 is provided on the side of the push plate 300 , the shape of which corresponds to the triangle at the top of the slider 430 , and is used to prevent the push plate 300 from moving upward when the cover 400 is engaged with the box body 100 .

[0056] Specifically, in the immunoassay kit, a sealing layer is provided on the lower surface of the cover plate 400 between the sliders 430 , and the sealing layer can cover the entire upper surface of the fixing frame 200 to seal the reagent tube.

[0057] It is understandable that during the immunoassay process, many reagents may be volatile or sensitive to environmental factors. The sealing layer can effectively prevent the reagents from volatilizing and maintain a stable concentration of the reagents in the reagent tube. Through the protection of the sealing layer, the chemical stability of the reagents can be ensured throughout the storage and detection process, thereby improving the accuracy of the test results.

[0058] Specifically, in the immunoassay kit, a buffer layer is provided on the upper surface of the push plate 300 to alleviate the squeezing force on the reagent tube.

[0059] It is understood that reagent tubes are typically made of glass or plastic, which are relatively fragile. Without a buffer layer, the squeezing force exerted by the push plate 300 when it pushes upward to contact the tube could cause the tube to rupture. The buffer layer effectively disperses and mitigates this squeezing force, preventing damage to the tube due to excessive localized pressure. For example, during transportation or if the test kit is subjected to unexpected vibrations, the buffer layer can prevent the tube from rupturing, ensuring that the reagent does not leak, thereby maintaining the integrity of the sample and reagents within the test kit.

[0060] Specifically, in the immunoassay kit, a handle portion 420 is provided on the upper surface of the cover 400 , and a buckle 410 is also provided on the upper surface of the cover 400 for tightly connecting the lower surface of the cover 400 with the upper surface of the box body 100 .

[0061] It can be understood that the hand-held part 420 is arranged so that the immunoassay kit can be conveniently lifted when it needs to be moved, and the user can easily carry the kit through the hand-held part 420 without directly holding the whole box by hand, which is particularly convenient when carrying multiple kits or holding other detection equipment at the same time; the presence of the buckle 410 enables the lower surface of the cover plate 400 to be tightly connected to the upper surface of the box body 100, forming a relatively closed space, which is crucial for the stability of the internal environment of the immunoassay kit. The kit may contain reagents and samples that are sensitive to environmental conditions, and the tight connection can prevent external air, dust, moisture, etc. from entering the inside of the box body 100, thereby protecting the reagents and samples from contamination and deterioration.

[0062] It can be understood by those skilled in the art that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
