Description

Technical Field

[0001] This invention belongs to the field of detection kit technology, specifically an immunoassay kit. Background Technology

[0002] In today's medical diagnostics, biological research, and public health control fields, accurate, rapid, and convenient testing methods are crucial. Immunoassay, as one of the core methods, plays an irreplaceable role in disease diagnosis, pathogen detection, and biomarker analysis due to its high sensitivity, high specificity, and wide range of applications. Immunoassay kits are the key tools enabling the widespread application of this technology.

[0003] Chinese patent CN221563901U discloses a chemiluminescence immunoassay kit. This kit separates the reagent bottles by using independent sponge blocks, preventing the bottles from interfering with each other. Even if one bottle leaks, it will not affect the others, thus solving the problem that existing test kits do not have protective measures for the reagent bottles.

[0004] The aforementioned immunoassay kit uses a sponge block to provide a cushioned and shock-absorbing storage environment for the reagent bottle. However, due to the friction between the sponge block and the reagent bottle, the operation of picking up and putting down the reagent bottle is not smooth enough. In particular, when picking up the reagent bottle with one hand, the box is easily lifted up due to excessive friction, which is not conducive to one-handed operation. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an immunoassay kit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an immunoassay kit, comprising a box body and a lid. The surface of the box body has multiple placement slots evenly distributed. Inside each placement slot, four arc-shaped plates are coaxially arranged at equal angles, with the upper ends of the arc-shaped plates extending to the outer side of the placement slot. A first sponge pad is provided on the inner side of each arc-shaped plate, and an arc-shaped compression block is provided on the outer surface of the upper end of each arc-shaped plate. The inner side of the lid has multiple clearance slots evenly distributed, corresponding to the placement slots. The edges of the openings of the clearance slots are chamfered, and the chamfered portions are press-fitted with the arc-shaped compression blocks.

[0007] Preferably, the inner wall of the placement groove is provided with a slot, and the outer surface of the arc plate is provided with an insert block, which is slidably disposed in the slot.

[0008] Preferably, the inner wall of the placement slot is provided with a groove, and a spring is provided inside the groove. One end of the spring is connected to the inner wall of the groove, and the other end of the spring is connected to the outer surface of the arc-shaped plate.

[0009] Preferably, a sealing ring is provided on the surface of the box body and on the outside of the placement groove, and the sealing ring is coaxially distributed with the placement groove.

[0010] Preferably, a second sponge pad is provided on the bottom wall of the placement groove.

[0011] Preferably, a lock is provided between the box body and the box lid, and a handle is installed on the outer surface of the box lid.

[0012] Preferably, the height of the arc-shaped plate on the outside of the box is lower than the depth of the relief groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the lid is closed on the box body, the curved extrusion blocks are squeezed by the chamfered part, which drives the four curved extrusion blocks in the same group to move towards the center of the placement groove. This causes the first sponge pad to clamp the outside of the reagent bottle, providing a clamping and fixing function to ensure the stability of the reagent bottle during transportation. When the lid is opened, the curved extrusion blocks lose their extrusion, and under the action of the spring, they can pull the four first sponge pads away from the surface of the reagent bottle. Then, the reagent bottle can be removed from the placement groove with one hand, avoiding the box body being lifted due to excessive friction. Furthermore, when placing the reagent bottle into the placement groove, it can avoid the friction of the first sponge pad that would cause the operation to be unsmooth, making it easy to operate with one hand.

[0022] 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.

[0023] like Figures 1 to 6 As shown, this utility model provides an immunoassay kit, including a box body 1 and a box cover 2. The surface of the box body 1 has a plurality of placement slots 101 evenly distributed. Four arc-shaped plates 102 are coaxially and equidistantly arranged inside the placement slots 101, with the upper ends of the arc-shaped plates 102 extending to the outer side of the placement slots 101. A first sponge pad 103 is provided on the inner side of the arc-shaped plates 102, and an arc-shaped compression block 104 is provided on the outer surface of the upper end of the arc-shaped plates 102. The inner side of the box cover 2 has a plurality of clearance slots 201 evenly distributed, and the clearance slots 201 correspond to the placement slots 101. A chamfered portion 202 is provided at the edge of the opening of the clearance slot 201, and the chamfered portion 202 is press-fitted with the arc-shaped compression block 104.

[0024] Insert the reagent bottle into the placement slot 101, then close the lid 2. The inner side of the lid 2 allows the chamfered portion 202 on the slot 201 to apply pressure to the arc-shaped compression block 104, thereby driving the four arc-shaped compression blocks 104 in the same group to move towards the center of the placement slot 101. This causes the first sponge pad 103 to clamp the outside of the reagent bottle, providing a clamping and fixing function to ensure the stability of the reagent bottle during transportation. When the lid 2 is opened, the arc-shaped compression block 104 loses its compression, and the clamping force of the first sponge pad 103 on the reagent bottle disappears. The reagent bottle can then be removed from the placement slot 101 with one hand, avoiding the situation where the box 1 is lifted due to excessive friction, and facilitating one-handed operation.

[0025] like Figures 5 to 6 As shown, the inner wall of the placement groove 101 has a slot 3, and the outer surface of the arc plate 102 is provided with an insert 301, which is slidably disposed in the slot 3. The inner wall of the placement groove 101 has a groove 4, and a spring 401 is disposed inside the groove 4. One end of the spring 401 is connected to the inner wall of the groove 4, and the other end of the spring 401 is connected to the outer surface of the arc plate 102.

[0026] The above solution is adopted: the slot 3 and the insert block 301 limit the arc plate 102, so that the arc extrusion block 104 can drive the arc plate 102 to move horizontally under the extrusion of the chamfered part 202, ensuring that the first sponge pad 103 has a uniform clamping force on the reagent bottle. When the arc plate 102 drives the first sponge pad 103 to clamp the reagent bottle, the spring 401 is stretched. When the lid 2 is opened to release the extrusion force of the chamfered part 202 on the arc extrusion block 104, the stretched spring 401 automatically retracts and drives the first sponge pad 103 away from the surface of the reagent bottle, so that the reagent bottle can be taken out of the placement slot 101 more conveniently. When placing the reagent bottle into the placement slot 101, the friction of the first sponge pad 103 can be avoided, which would cause the operation to be difficult, making it easy to operate with one hand.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, a sealing ring 5 is provided on the surface of the box body 1 and outside the placement groove 101, and the sealing ring 5 is coaxially distributed with the placement groove 101. The height of the arc plate 102 outside the box body 1 is lower than the depth of the relief groove 201.

[0028] The above solution ensures that when the lid 2 is closed, its lower surface presses against the sealing ring 5, thus achieving a seal and individually sealing each reagent bottle in the placement slot 101, preventing leakage during transportation that could contaminate other reagent bottles. Furthermore, when the lid 2 is closed, the outer portion of the arc-shaped plate 102 can be fully inserted into the clearance slot 201, without affecting the complete closure of the lid 2.

[0029] like Figures 1 to 5 As shown, a second sponge pad 6 is provided on the bottom wall of the placement slot 101. A lock is provided between the box body 1 and the box cover 2, and a handle is installed on the outer surface of the box cover 2.

[0030] Using the above solution: the second sponge pad 6 can cushion and protect the bottom of the reagent bottle, reducing the risk of impact. After the lid 2 is closed to the box body 1 with the lock, it can be carried by the handle.

[0031] Working principle and usage process of this utility model:

[0032] When placing the reagent bottle, first open the lid 2. At this time, the arc plate 102 can stick to the inner wall of the placement groove 101 under the pulling force of the spring 401. Then the reagent bottle can be directly placed into the placement groove 101. Since the inner diameter of the four first sponge pads 103 is larger than the diameter of the reagent bottle, the friction of the first sponge pads 103 can be avoided, which may cause the operation to be difficult. After the reagent bottle is placed, close the lid 2. Use the chamfered part 202 on the inner side of the lid 2 to apply pressure to the arc-shaped extrusion block 104, thereby driving the four arc-shaped extrusion blocks 104 in the same group to move towards the center of the placement groove 101, and driving the first sponge pads 103 to clamp the outside of the reagent bottle, providing a clamping and fixing function, and ensuring the stability of the reagent bottle during transportation.

[0033] When the lid 2 is opened, the arc-shaped squeezing block 104 loses its squeezing force. Under the action of the spring 401, it can pull the four first sponge pads 103 away from the surface of the reagent bottle. Then, the reagent bottle can be taken out from the placement slot 101 with one hand, avoiding the situation where the box 1 is lifted due to excessive friction, which is convenient for one-handed operation.
