Description

Technical Field

[0001] This invention relates to the field of mixers, specifically a rapid mixer for semi-quantitative ferritin assay kits. Background Technology

[0002] The use of a sample mixer in semi-quantitative ferritin assay kits is crucial to ensuring the accuracy, reliability, and consistency of test results. Ferritin assays are typically based on principles such as immunochromatography or enzyme-linked immunosorbent assay (ELISA). These methods are highly sensitive to the binding reaction between the target antigen and the labeled antibody or test reagent in the sample. If the sample is not thoroughly mixed, ferritin may exhibit a concentration gradient due to precipitation, adsorption, or uneven distribution. This results in the amount of antigen in contact with the reagent reaction area not representing the true concentration of the sample, thus causing deviations in the detection signal and affecting the interpretation of semi-quantitative results. Furthermore, ferritin in blood or serum samples may change after standing due to… Due to gravity, some ferritin may settle or undergo non-specific adsorption with the tube wall. When sampling directly, the concentration of ferritin in the liquid drawn from different depths of the pipette may vary significantly. Using a dedicated sample mixer, through gentle but continuous rotation, vortexing, or repeated inversion mixing, this uneven state can be broken, allowing ferritin to be redistributed evenly throughout the liquid matrix. This not only ensures the consistency of each sampling but also ensures a stable and reliable dynamic process of antigen-antibody binding during subsequent reactions with test reagents. As a result, the correlation between the colorimetric reaction and the ferritin concentration is more consistent with the preset range of the standard curve or colorimetric card.

[0003] In existing technologies, when mixing test reagents or samples, manual shaking or the use of a rotating device is usually relied upon. If manual shaking is used, the operator needs to continuously apply physical force to repeatedly shake, which is time-consuming, labor-intensive, and inefficient. Moreover, the mixing effect is easily inconsistent due to operator fatigue or differences in technique, which directly affects the accuracy and repeatability of subsequent test results. Another common method, rotational mixing, although reducing some labor consumption, usually relies on the slow rotation of the container around the axis. For liquids with high viscosity, easy precipitation, or those that require rapid and uniform mixing, its mixing efficiency is often insufficient, and the mixing time is long. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rapid sample mixer for semi-quantitative ferritin detection kits, solving the problem of low efficiency caused by manually mixing or rotating the reagents.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid sample mixer for a semi-quantitative ferritin detection kit, comprising a shell, a fixed plate installed inside the shell, the fixed plate being fixed to the inner wall of the shell via a connecting column, a connecting frame above the fixed plate, the connecting frame being fan-shaped, and multiple arc-shaped blocks movably connected to the connecting frame, the arc-shaped blocks being equidistantly and staggered around their circumference, each arc-shaped block being provided with a clamping mechanism for clamping test tubes or containers, a drive shaft being eccentrically mounted at the bottom of the connecting frame, and an oscillation component being provided on the fixed plate, the arc-shaped blocks, and the connecting frame.

[0006] Through the above technical solution: by cooperating with the oscillation component and the drive motor, the equipment can achieve efficient mixing of reagents in test tubes. After the motor starts, the eccentric rotation of the connecting frame and the arc-shaped block causes the test tube to rotate at high speed. At the same time, the pressing of the drive block and the adapter block not only causes the arc-shaped block to move back and forth in the vertical direction, but also causes a slight horizontal sway. This combination of multi-dimensional motion ensures that the reagents in the test tube are mixed quickly and evenly in a very short time, thereby significantly improving work efficiency. Meanwhile, the clamping mechanism uses an adjustable pull rod to hold the test tube, effectively preventing the test tube from falling and breaking during the mixing process. During mixing, the fixation of the test tube can significantly reduce the risk of falling off due to external vibration or high-speed rotation, avoiding sample contamination and loss. This not only improves the stability of the equipment, but also provides a safer environment for operators and reduces the risk of personal injury caused by accidents during the experiment.

[0007] Preferably, the oscillation assembly includes a driving block installed at the bottom of the arc-shaped block, an adapter block installed on the fixed disk, the bottom end of the driving block and the top end of the adapter block are both conical, the driving block and the adapter block cooperate to drive the arc-shaped block to move upward, the width of the adapter block is greater than the width of the driving block, the oscillation assembly also includes a long plate installed at the end of the arc-shaped block, the side wall of the connecting frame has multiple grooves, the long plate is inserted into the grooves, a first spring is installed on the long plate, and the other end of the first spring is connected to the upper wall of the groove.

[0008] Preferably, the clamping mechanism includes a square groove opened on the arc-shaped block, racks symmetrically installed on the inner wall of the square groove, and a slider installed at the bottom of the square groove. The slider slides in the square groove, a pair of baffles are installed on the upper surface of the slider, and a second spring is provided between the baffles. One end of the second spring is connected to the upper surface of the slider, and the other end of the second spring is connected to a toothed block. The toothed block meshes with the rack. Stops are symmetrically installed on the inner wall of the square groove. The stops are located above the rack, and the distance between the stops is less than the width of the toothed block. A clamping claw is installed on one side wall of the slider.

[0009] Preferably, each of the arc-shaped blocks is equipped with a limiting rod on both sides, the limiting rod supports the arc-shaped block, and the connecting frame has a straight groove that is compatible with the limiting rod. The limiting rod is inserted into the straight groove, and the width of the straight groove is greater than the diameter of the limiting rod.

[0010] Preferably, each of the arc-shaped blocks has a holding slot for placing test tubes or containers.

[0011] Preferably, the gripping claw is curved, a first rubber strip is installed on the side wall of the gripping claw, and a second rubber strip is installed on the side wall of the holding groove.

[0012] Preferably, a protective shell is installed at the bottom of the outer casing, and a drive motor is provided inside the protective shell. The output end of the drive motor is connected to one end of the transmission shaft.

[0013] Preferably, the upper end of the toothed block is provided with a pull rod. When the pull rod is pressed down, the toothed block disengages from the rack and moves up and down within the baffle.

[0014] Preferably, a rubber pad is installed at the bottom of the outer casing, and a top cover is provided at the top of the outer casing.

[0015] Preferably, when the connecting frame rotates, the lower end of each driving block abuts against the upper end of the adapter block.

[0016] Working principle: During operation, open the top cover and place the test tube into the holding slot. Press down the pull rod to move the toothed block downwards, disengaging it from the rack. Simultaneously, the second spring deforms as the toothed block presses down, pulling the pull rod outwards. This causes the toothed block, second spring, slider, and clamping claw to move outwards together. Place the test tube into the holding slot and push the pull rod to ensure the clamping claw fits tightly against the outer wall of the test tube. Release the pull rod; the second spring rebounds, pushing the toothed block upwards between the rack to secure it. Start the drive motor, which rotates the transmission shaft, thereby rotating the connecting frame and the arc-shaped block. As the connecting frame rotates the arc-shaped block, the drive block moves in a circular motion, its conical bottom periodically contacting, pressing against, and opposing the conical top surface of the adapter block. During sliding, due to the larger width of the adapter block, the driving block generates an upward thrust along the conical surface of the adapter block during rotation, causing the entire arc-shaped block to rise upward. Simultaneously, because the drive shaft is eccentrically mounted at the bottom of the connecting frame, each driving block follows a different circular trajectory. However, the larger width of the adapter block ensures that each driving block can contact and press against the adapter block during rotation. When the arc-shaped block moves upward, the first spring deforms. When the driving block rotates away from the adapter block, the thrust disappears, and the arc-shaped block quickly falls back under its own weight and the restoring pull of the first spring, completing one vertical reciprocating motion. This process repeats in subsequent operations. Because the diameter of the limiting rod is smaller than the width of the straight groove, the arc-shaped block also experiences slight horizontal swaying during rotation, achieving multi-dimensional motion.

[0017] This invention provides a rapid sample mixer for a semi-quantitative ferritin detection kit. It offers the following advantages:

[0018] 1. This invention achieves efficient and thorough mixing of reagents in test tubes through the oscillation component and drive motor. After the drive motor is started, the drive connecting frame and the arc-shaped block installed on it rotate eccentrically, thereby driving the test tube to rotate at high speed. At the same time, during the rotation of the connecting frame, the drive block on it will periodically contact the adapter block and generate pressure, causing the arc-shaped block to reciprocate in the vertical direction and shake slightly in the horizontal direction. Under the multi-dimensional motion of high-speed rotation, vertical oscillation and horizontal slight shaking, the reagents in the test tube can achieve rapid and uniform mixing in a short time, significantly improving the mixing efficiency and effect.

[0019] 2. This invention, through its clamping mechanism, clamps the test tubes when they are placed in the holding tank by pulling a lever, preventing them from falling off and being damaged during the mixing process. This ensures the stability and safety of the equipment, avoids the risk of sample spillage, contamination, and test tube breakage caused by accidental test tube detachment, and also prevents collision damage to internal components of the equipment due to loose test tubes. This significantly improves the safety and reliability of the entire mixing process, enabling the equipment to maintain stable operation during long-term work, while providing a safer experimental environment for operators.

[0020] 3. The invention, through the provision of a first rubber strip and a second rubber strip, effectively avoids the risk of scratches, indentations, or even breakage on the surface of the test tube due to rigid contact between the test tube and the clamping claws during clamping.

[0021] Meanwhile, the high coefficient of friction of the rubber material further increases the stability of the test tube during high-speed rotation. Attached Figure Description

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example:

[0033] Reference Figure 1 and Figure 2 as well as Figure 3 This invention provides a rapid sample mixer for a semi-quantitative ferritin detection kit, comprising a housing 1, a fixed plate 2 installed inside the housing 1, the fixed plate 2 being fixed to the inner wall of the housing 1 by a connecting column, a connecting frame 3 above the fixed plate 2, the connecting frame 3 being fan-shaped, and multiple arc-shaped blocks 4 being movably connected to the connecting frame 3, the arc-shaped blocks 4 being equidistantly staggered around their circumference, each arc-shaped block 4 being provided with a clamping mechanism 5 for clamping test tubes or containers, a drive shaft 6 being eccentrically mounted at the bottom of the connecting frame 3, and an oscillation component 7 being provided on the fixed plate 2, the arc-shaped blocks 4, and the connecting frame 3.

[0034] Specifically, the oscillation component 7 and the drive motor 13 work together to achieve multi-dimensional motion of the test tube during mixing, including eccentric rotation, vertical oscillation, and horizontal micro-shaking. This effectively solves the problems of low efficiency and uneven mixing in traditional single-rotation mixing methods. After the drive motor 13 is started, the eccentric rotation of the connecting frame 3 drives the test tube to perform high-speed circular motion, causing the reagent inside the test tube to produce a centrifugal stirring effect. At the same time, the drive block 701 and the adapter block 702 of the oscillation component 7 periodically cooperate to drive the test tube to perform high-frequency vertical reciprocating oscillation, breaking the laminar flow state inside the reagent. The gap fit between the limiting rod 8 and the straight groove allows the arc-shaped block 4 to move vertically simultaneously. The slight horizontal shaking further enhances the reagent mixing effect. The three motion modes act simultaneously on the test tube, causing the reagent molecules to move violently in a short time. This not only significantly shortens the mixing time but also ensures that the reagent components are fully contacted and uniformly mixed, avoiding local concentration deviations from affecting the accuracy of semi-quantitative detection results. In addition, the width of the adapter block 702 is greater than the width of the drive block 701, allowing each drive block 701 to contact the adapter block 702, thereby driving the arc block 4 to oscillate vertically. The elastic buffering effect of the first spring 704 further controls the oscillation rhythm, ensuring the mixing effect while reducing damage to the sample in the test tube.

[0035] Reference Figure 3 and Figure 4 as well as Figure 5The oscillation assembly 7 includes a drive block 701 installed at the bottom of the arc-shaped block 4, and an adapter block 702 installed on the fixed disk 2. The bottom end of the drive block 701 and the top end of the adapter block 702 are both conical. The drive block 701 and the adapter block 702 cooperate with each other to drive the arc-shaped block 4 to move upward. The width of the adapter block 702 is greater than the width of the drive block 701. The oscillation assembly 7 also includes a long plate 703 installed at the end of the arc-shaped block 4. The side wall of the connecting frame 3 has multiple grooves. The long plate 703 is inserted into the grooves. A first spring 704 is installed on the long plate 703. The other end of the first spring 704 is connected to the upper wall of the groove.

[0036] Specifically, through the oscillation component 7, both the drive block 701 installed at the bottom of the arc-shaped block 4 and the adapter block 702 on the fixed disk 2 adopt a conical end face design, and the width of the adapter block 702 is greater than the width of the drive block 701. When the connecting frame 3 drives the arc-shaped block 4 to rotate, the drive block 701 moves in a circular motion with the arc-shaped block 4. Its conical bottom end will periodically contact, press against, and slide relative to the conical upper end face of the adapter block 702. Because the adapter block 702 is wider, the drive block 701 will generate an upward pushing force along the conical surface of the adapter block 702 during rotation, causing the arc-shaped block 4 to lift upward as a whole. At the same time, since the transmission shaft 6 is eccentrically installed at the bottom of the connecting frame 3, that is, the trajectory of each drive block 701 in circular motion is different, but the adapter block 702 is wider, so that each drive block 701 can contact and press against the adapter block 702 during rotation. When the arc-shaped block 4 When moving upward, the first spring 704 deforms. When the drive block 701 rotates and disengages from the adapter block 702, the pushing force disappears, and the arc-shaped block 4 quickly falls back under its own weight and the restoring pull of the first spring 704, completing one reciprocating motion in the vertical direction. Since the diameter of the limiting rod 8 is smaller than the width of the straight groove, the arc-shaped block 4 also wobbles slightly in the horizontal direction during rotation, achieving multi-dimensional motion and accelerating the mixing of reagents. The limiting rods 8 installed on both sides of each arc-shaped block 4 cooperate with the straight groove on the connecting frame 3 to support the arc-shaped block 4. At the same time, the long plate 703 and the first spring 704 further support the arc-shaped block 4. The width of the straight groove is slightly larger than the diameter of the limiting rod 8, so that the arc-shaped block 4 performs reciprocating oscillating motion in the horizontal direction and prevents the arc-shaped block 4 from shifting or jamming during the combined rotation and oscillation motion, ensuring stable operation of the equipment.

[0037] Reference Figure 6 and Figure 7 as well as Figure 8The clamping mechanism 5 includes a square groove opened on the arc-shaped block 4. A rack 501 is symmetrically installed on the inner wall of the square groove. The clamping mechanism 5 also includes a slider 502 installed at the bottom of the square groove. The slider 502 slides in the square groove. A pair of baffles 503 are installed on the upper surface of the slider 502. A second spring 504 is provided between the baffles 503. One end of the second spring 504 is connected to the upper surface of the slider 502. The other end of the second spring 504 is connected to a toothed block 505. The toothed block 505 meshes with the rack 501. A stop block 506 is symmetrically installed on the inner wall of the square groove. The stop block 506 is located above the rack 501. The distance between the stop blocks 506 is less than the width of the toothed block 505. A clamping claw 507 is installed on one side wall of the slider 502.

[0038] Specifically, the clamping mechanism 5, through the engagement of the rack 501 and the toothed block 505 with the cooperation of the second spring 504, achieves adaptive clamping of test tubes of different diameters without the need to change to special clamps, greatly improving the versatility of the equipment. It can be adapted to different specifications of reaction tubes, sampling tubes, and other containers in semi-quantitative ferritin detection kits. During the clamping process, the cooperation between the curved clamping claw 507 and the first rubber strip 10 not only achieves stable clamping but also provides a buffering and protective function for the test tubes, avoiding sample spillage and contamination risks caused by test tube breakage. In semi-quantitative detection experiments, samples are usually clinical blood, serum, etc., and may be biohazardous. Sample breakage in test tubes not only results in sample loss but may also lead to biological contamination and threaten the health of operators. The clamping mechanism 5 avoids this risk. At the same time, the clamping mechanism 5 uses the meshing of the rack 501 and the toothed block 505 to fix the test tube in the holding tank 9, ensuring that the test tube remains stable during high-speed rotation and violent vibration. This prevents the test tube from loosening or falling off and colliding with internal components of the equipment, thus preventing the test tube from breaking and protecting the internal drive and transmission components of the equipment. This reduces the failure rate of the equipment, extends the service life of the equipment, and enables the equipment to maintain a stable clamping effect during long-term continuous operation.

[0039] Reference Figure 4 and Figure 5 Each arc-shaped block 4 has a limit rod 8 installed on both sides. The limit rod 8 supports the arc-shaped block 4. The connecting frame 3 has a straight groove that matches the limit rod 8. The limit rod 8 is inserted into the straight groove, and the width of the straight groove is greater than the diameter of the limit rod 8.

[0040] Specifically, the limiting rod 8 and the straight groove are designed to support the arc-shaped block 4. The limiting rod 8 is inserted into the straight groove to support the arc-shaped block 4. Even when the arc-shaped block 4 is rotating at high speed, it will not fall off, thus increasing the stability of the equipment. The width of the straight groove is slightly larger than the diameter of the limiting rod 8, which allows the arc-shaped block 4 to sway slightly in the horizontal direction when rotating at high speed, further enhancing the mixing effect.

[0041] Reference Figure 7Each arc-shaped block 4 has a holding groove 9 for placing test tubes or containers; the clamping claw 507 is curved, and a first rubber strip 10 is installed on the side wall of the clamping claw 507, and a second rubber strip 11 is installed on the side wall of the holding groove 9.

[0042] Specifically, by setting the first rubber strip 10 and the second rubber strip 11, the rubber material itself has elasticity and flexibility during the clamping process of the test tube, which can form a buffer layer, effectively avoiding rigid contact between the test tube and the clamping claw 507 and the holding groove 9. This effectively avoids the problem of the test tube being easily scratched, indented, or even broken due to rigid contact. Compared with materials such as metal and hard plastic, the rubber material has a higher coefficient of friction. The tight fit between the first rubber strip 10 and the second rubber strip 11 and the side wall of the test tube can significantly increase the friction between the test tube and the clamping claw 507 and the holding groove 9, even under the operation of high-speed rotation and high-frequency vibration of the equipment, effectively suppressing the sliding or even falling off of the test tube.

[0043] Reference Figure 4 and Figure 6 A protective shell 12 is installed at the bottom of the outer shell 1. A drive motor 13 is installed inside the protective shell 12. The output end of the drive motor 13 is connected to one end of the transmission shaft 6. A pull rod is provided at the upper end of the toothed block 505. When the pull rod is pressed down, the toothed block 505 disengages from the rack 501 and moves up and down in the baffle 503.

[0044] Specifically, the engagement of the rack 501 and the toothed block 505 further ensures the stability of the test tube during the mixing process.

[0045] Reference Figure 1 and Figure 3 A rubber pad 14 is installed at the bottom of the outer shell 1, and a top cover is provided at the top of the outer shell 1; when the connecting frame 3 rotates, the lower end of each drive block 701 abuts against the upper end of the adapter block 702.

[0046] Specifically, the rubber pad 14 absorbs vibrations generated during equipment operation by utilizing the elastic cushioning properties of the rubber material, reducing resonance between the equipment and the placement surface and lowering operating noise. The high coefficient of friction of rubber enhances the anti-slip performance of the equipment during placement, preventing displacement of the equipment during high-speed rotation and vibration. The top cover design of the outer shell 1 creates a closed environment during equipment operation, preventing external dust and impurities from entering the equipment and affecting the operation of transmission components. It also prevents sample splashing when test tubes are accidentally ejected, further improving operational safety.
