[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. The device cover is opened by a hinge, and the test strips are stored inside the storage box of the device body. A drying groove is opened on one side of the storage box to dry the test strips stored inside, avoiding the problem of inaccurate test results due to moisture inside the box. The disinfection spray is fixed by a magnetic strip inside the disinfection box. Pressing the disinfection spray disinfects the hands, avoiding the influence of bacteria on the sampling and inaccurate test results. The isolation plate divides the inside into a sampling area and a testing area to prevent accidental contamination of the device body during the sampling process, thus avoiding the waste of internal test strips and preventing re-contamination. The puncture needle inside the device cover punctures the inside of the collection tube to allow the internal sampling liquid and culture medium to flow onto the test strip. The puncture needle cap seals the puncture needle to prevent contamination. The suction cup fixes the device body to help keep the internal test strips in a horizontal position, avoiding misalignment of the collection tube and test strip due to test misalignment, thus improving the detection accuracy.

[0017] 2. In this utility model, telescopic rod holes are provided on both sides of the device body, and telescopic rods are inserted into the telescopic rod holes. The telescopic rods cause the spring to deform and compress the elastic ring through the protrusions inside the spring. The gears inside the elastic ring then compress the collection tube, ensuring that the collection liquid and culture medium inside are fully and evenly mixed. This avoids the problem of inaccurate test results due to uneven mixing of the collection liquid. The sealing cap seals the collection tube to prevent contamination of the internal culture medium and to prevent the test reagents from becoming ineffective due to contamination. The collection liquid inside flows into the test strip by puncturing the lower surface of the collection tube.

[0018] 3. In this utility model, a balance connecting block is rotatably connected inside the balance shaft seat. The balance connecting block drives the balance frame to adjust to a horizontal position. The counterweight causes the adjusting rods on both sides of the test strip frame to adjust the angle of the test strip frame, keeping the test strip inside horizontal. This allows the drop frame on the upper surface of the test strip to quickly immerse the reagent strip inside the test strip while maintaining a horizontal position, making the detection time faster and more accurate. It also avoids the overflow of the sample collected inside the drop frame due to displacement and tilt. The drop frame has spikes inside, allowing the collection tube to be inserted into the collection hole on the upper surface of the device cover, so that the spikes can penetrate into the collection tube. The sample collected inside flows into the drop frame along the spikes. The test strip is located on the side of the device body near the storage box. The observation window on the upper surface of the device cover allows you to see the detection status of the test strip and the dripping of the collected sample, greatly improving the detection efficiency.

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.

[0025] Example: Reference Figures 1-4An immunoassay kit is shown, comprising a device body 1, a storage box 2 inside the device body 1, a disinfection box 3 inserted into one side of the device body 1, a disinfection spray 4 inside the disinfection box 3, a suction cup 5 on the lower surface of the device body 1, an isolation plate 6 inserted into the inside of the device body 1, a hinge 7 rotatably connected to one side of the device body 1, a device cover 8 on one side of the hinge 7, a puncture needle 9 inside the device cover 8, a puncture needle cap 10 inserted into the inside of the device cover 8, and telescopic rods 11 inserted into both sides of the device body 1. Springs 12 are sleeved on the outer surface of the telescopic rods 11. One side of the device is provided with an elastic rubber ring 13, inside which is provided a collection tube 14, and inside the collection tube 14 is a sealing cap 15. Inside the device body 1 is provided a balance shaft seat 16, inside which is rotatably connected a balance connecting block 17. One side of the balance connecting block 17 is provided with a balance frame 18, inside which is inserted an adjustment shaft seat 19, inside which is rotatably connected an adjustment rod 20, one side of the adjustment rod 20 is fitted with a detection strip frame 21, the lower surface of the detection strip frame 21 is fixedly connected with a counterweight block 22, and inside the detection strip frame 21 is provided a test strip 23.

[0026] As a preferred embodiment of this example, Figure 2As shown, the device body 1 has a storage box 2 inside, a disinfection box 3 inserted into one side of the device body 1, a disinfection spray 4 inside the disinfection box 3, a suction cup 5 on the lower surface of the device body 1, an isolation plate 6 inserted into the inside of the device body 1, a hinge 7 rotatably connected to one side of the device body 1, a device cover 8 on one side of the hinge 7, a puncture needle 9 inside the device cover 8, a puncture needle cover 10 inserted into the inside of the device cover 8, grooves are formed on both sides of the inside of the device body 1 near the middle, the grooves are adapted to the isolation plate 6, and a temperature... A temperature sensor is present. A magnetic strip is located on one side of the interior of the disinfection box 3. An iron ring is fitted onto the outer surface of the disinfection spray 4, and the iron ring and magnetic strip are compatible. An arc-shaped groove, the same size as the disinfection spray 4, is located on one side of the disinfection box 3 near its upper surface. A fixing bolt is located inside the device body 1, with its thread penetrating the hinge 7, the device body 1, and the device cover 8. A desiccant recess is located inside the storage box 2. A desiccant box is located near one side of the interior of the device body 1. Both the desiccant box and the storage box 2 contain desiccant, and the interior of the desiccant box is hollow. During use, the device cover 8 is opened via hinge 2, and the reagent strips are stored inside the storage box 2 within the device body 1. A drying groove on one side of the storage box 2 allows the desiccant inside to dry and preserve the stored reagent strips, preventing inaccurate test results due to moisture inside the box. The disinfection spray 4 is secured by a magnetic strip inside the disinfection box 3. Pressing the disinfection spray 4 disinfects the hands, preventing bacteria on the hands from affecting sampling and causing inaccurate test results. The partition 6 divides the interior into a sampling area and a testing area. To prevent accidental contamination of the device body 1 during sampling, thus avoiding the waste of internal reagent strips and preventing re-contamination, a puncture needle inside the device cover 8 is used to puncture the inside of the collection tube 14, allowing the sampling liquid and culture medium inside to flow out onto the test strip 23. The puncture needle 9 is sealed and stored by the puncture needle cover 10 to prevent contamination of the puncture needle. The suction cup 5 fixes the device body 1 to help keep the internal test strip 23 in a horizontal position, preventing misalignment and tilting of the collection tube 14, which would cause the test strip 23 to misalign, thus improving the detection accuracy.

[0027] like Figure 2 and Figure 3As shown, in this embodiment, telescopic rods 11 are inserted into both sides of the device body 1. A spring 12 is sleeved on the outer surface of the telescopic rod 11. An elastic rubber ring 13 is provided on one side of the spring 12. A collection tube 14 is provided inside the elastic rubber ring 13, and a sealing cap 15 is inserted inside the collection tube 14. The elastic rubber ring 13 is hollow and has a gear-shaped groove inside. The collection tube 14 is also hollow, and a connecting strip is provided on one side of the collection tube 14 and the sealing cap 15. During use, telescopic rod holes are provided on both sides of the device body 1. An internal telescopic rod 11 is inserted, which compresses and deforms the spring 12. The protrusion inside the spring 12 compresses the elastic ring 13, and the gear inside the elastic ring 13 compresses the collection tube 14, ensuring that the collection solution and culture solution inside are fully mixed and uniform. This avoids the problem of inaccurate test results due to uneven mixing of the collection solution. The sealing cap 15 seals the collection tube 14 to prevent contamination of the internal culture solution and to prevent the test reagent from becoming ineffective due to contamination. The collection solution inside flows into the test strip 23 by puncturing the lower surface of the collection tube 14.

[0028] As shown in the figure and Figure 4 As shown, in this embodiment, the device body 1 has a balance shaft seat 16 inside, a balance connecting block 17 is rotatably connected inside the balance shaft seat 16, a balance frame 18 is provided on one side of the balance connecting block 17, an adjustment shaft seat 19 is inserted inside the balance frame 18, an adjustment rod 20 is rotatably connected inside the adjustment shaft seat 19, a detection strip frame 21 is sleeved on one side of the adjustment rod 20, a counterweight 22 is fixedly connected to the lower surface of the detection strip frame 21, a test strip 23 is provided inside the detection strip frame 21, the counterweight 22 is semi-circular in shape, and the plane of the counterweight 22 is fixedly connected to the lower surface of the detection strip frame 21. During use, the balance connecting block 17 is rotatably connected inside the balance shaft seat 16, the balance connecting block 17 drives the balance frame 18 to be adjusted to the horizontal direction, and the counterweight 22 makes the detection strip frame 23... The adjusting rods 20 on both sides drive the detection strip frame 21 to adjust its angle, so that the detection strip 23 inside is kept horizontal. The drop frame on the upper surface of the detection strip 23 is kept horizontal and quickly immersed in the reagent strip inside the detection strip 23, making the detection time faster and more accurate. It avoids the overflow of the sample collected inside the drop frame due to displacement and tilt. The spikes inside the drop frame allow the collection tube 14 to be inserted into the collection hole on the upper surface of the device cover plate 8, so that the spikes can be inserted into the inside of the collection tube 14. The sample collected inside flows into the inside of the drop frame along the spikes. The detection strip 23 is located on the side of the device body 1 near the storage box 2. The detection status of the detection strip 23 and the drop status of the collected sample can be seen through the observation window on the upper surface of the device cover plate 8, which greatly improves the detection efficiency.

[0029] The working principle of this practical application is as follows:

[0030] During use, the device cover 8 is opened via hinge 2, and the reagent strips are stored inside the storage box 2 within the device body 1. A drying groove on one side of the storage box 2 allows the desiccant inside to dry and preserve the stored reagent strips, preventing inaccurate test results due to moisture inside the box. The disinfection spray 4 is secured by a magnetic strip inside the disinfection box 3. Pressing the disinfection spray 4 disinfects the hands, preventing bacteria on the hands from affecting sampling and causing inaccurate test results. The partition 6 divides the interior into a sampling area and a testing area, preventing accidental contamination of the device body 1 during sampling and thus avoiding the waste of the internal reagent strips and preventing recontamination. A puncture needle inside the device cover 8 punctures the inside of the collection tube 14, allowing the sampling liquid and culture medium inside to flow out onto the test strip 23. The puncture needle 9 is sealed and stored by the puncture needle cover 10 to prevent contamination. The device body 1 is fixed by the suction cup 5 to help keep the internal test strip 23 horizontal, preventing misalignment and tilting of the collection tube 14, thus improving detection accuracy. Telescopic rod holes are provided on both sides of the device body 1, and telescopic rods 11 are inserted into these holes. The telescopic rods 11 cause the spring 12 to deform, and the protrusions inside the spring 12 compress the elastic ring 13, causing the elastic ring 13 to... The gears squeeze the collection tube 14 to ensure that the collection liquid and culture medium inside are fully mixed evenly, avoiding inaccurate test results due to uneven mixing of the collection liquid. The sealing cap 15 seals the collection tube 14 to prevent contamination of the internal culture medium and to prevent the test reagents from becoming ineffective due to contamination. By puncturing the lower surface of the collection tube 14, the collection liquid inside flows into the test strip 23. The balance connecting block 17 is rotatably connected inside the balance shaft seat 16. The balance connecting block 17 drives the balance frame 18 to be adjusted to a horizontal position. The counterweight 22 causes the adjusting rods 20 on both sides of the test strip frame 21 to adjust the angle of the test strip frame 21, so that the test strip 23 inside is kept horizontal. The test strip 23 is positioned so that the droplet frame on its upper surface is quickly immersed in the reagent strip inside the test strip 23 while maintaining a horizontal position. This makes the detection time faster and more accurate, and avoids the overflow of the sample collected inside the droplet frame due to displacement or tilting. The droplet frame has spikes inside, which allow the collection tube 14 to be inserted into the collection hole on the upper surface of the device cover plate 8 so that the spikes can penetrate into the collection tube 14. The sample collected inside flows into the droplet frame along the spikes. Since the test strip 23 is located on the side of the device body 1 near the storage box 2, the detection status of the test strip 23 and the droplet status of the collected sample can be seen through the observation window on the upper surface of the device cover plate 8, which greatly improves the detection efficiency.
