Technical Field

[0001] This utility model relates to the field of quantitative fluorescence detection technology for ractopamine, specifically a quantitative fluorescence detection kit for ractopamine. Background Technology

[0002] Ractopamine is a drug used by humans and veterinarians to treat asthma. In livestock, overdose can convert adipose tissue into muscle tissue. Because it can significantly improve fat percentage and production efficiency, there are some illegal cases of using ractopamine to replace clenbuterol as a feed additive. Therefore, it is necessary to use a ractopamine fluorescence quantitative detection kit for detection.

[0003] In the existing technology, a reagent kit for the quantitative detection of ractopamine with fluorescence is disclosed, with patent number CN201120403867.3. It uses a mixture of fluorescein and ractopamine antigen, and the mixed solution is dropped onto a test strip for detection.

[0004] However, the mixing process of fluorescein and ractopamine antigen requires manual stirring, which results in low stirring efficiency. Furthermore, existing stirring blades are generally fixed to the rotating shaft and cannot be disassembled, leading to insufficient cleaning and subsequent contamination during use, thus causing errors in the detection results. Therefore, these methods do not meet the current requirements. To address this, we propose a ractopamine fluorescence quantitative detection kit. Utility Model Content

[0005] The purpose of this invention is to provide a ractopamine fluorescence quantitative detection kit to solve the problems mentioned in the background art, such as the need for manual mixing of fluorescein and ractopamine antigen in the existing technology, which results in low mixing efficiency; at the same time, the existing stirring blades are generally fixed on the rotating shaft and cannot be disassembled, resulting in insufficient cleaning and mixing contamination in the next use, which in turn leads to errors in the detection results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ractopamine fluorescence quantitative detection kit, comprising an outer fixation frame, a kit inserted into the inner side of the outer fixation frame, a first storage cavity provided on the upper side of the kit, a stirring box inserted inside the first storage cavity, a motor fixing cavity provided at the bottom of the stirring box, a micro motor fixedly connected to the bottom of the motor fixing cavity, a partition fixedly connected around the micro motor, an output end of the micro motor extending through the partition to the upper side of the stirring box, and multiple stirring blades snapped onto the output end of the micro motor;

[0007] Both sides of the bottom of the first storage cavity are fixedly connected to a fixing block. The fixing block has an inner cavity. A through hole is transversely provided in the middle of the inner cavity. A movable column is transversely movably provided inside the through hole. A second movable plate is fixedly connected to the upper and lower sides of one end of the movable column. A spring is connected to one end of the second movable plate.

[0008] Preferably, the mixing box has fixing grooves on both sides, one end of the movable column passes through the middle of the inner cavity, and the other end of the movable column is inserted into the fixing groove.

[0009] Preferably, the second movable plate moves inside the inner cavity, and one end face of the two second movable plates and one end face inside the inner cavity are connected by a spring.

[0010] Preferably, the output end of the micro motor is connected to a rotating shaft via a coupling, and metal clips are fixedly connected to both sides of the rotating shaft, with a connecting block clipped to the upper end of the rotating shaft.

[0011] Preferably, the cross-section of the connecting block is designed as an inverted U-shaped structure, and both sides of the inside of the connecting block are provided with snap-fit ​​grooves, and the metal snap-fit ​​pieces on both sides of the rotating shaft are snapped into the snap-fit ​​grooves.

[0012] Preferably, the lower side of the reagent kit is provided with a second storage cavity, the test strip is placed inside the second storage cavity, and the front and rear sides of the second storage cavity are both secured with a first movable plate.

[0013] Preferably, an end cap is snapped onto the upper end of the first storage cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model involves pouring fluorescein into a stirring box inside the first storage chamber, then turning on the micro motor. The rotating shaft on the micro motor rotates, which in turn rotates the connecting block and stirring blade at the top. This allows the stirring blade to mix the fluorescein and the collected ractopamine antigen liquid inside the stirring box. The micro motor, rotating shaft, connecting block, and stirring blade replace the existing manual stirring, which greatly improves the stirring efficiency.

[0016] 2. This utility model allows the connecting block and stirring blade to move outward by pulling them together. Since the metal clips are made of elastic metal, their deformation during the pulling process allows the connecting block and rotating shaft to separate quickly. The user can then clean the surface of the stirring blade and insert the cleaned stirring blade and connecting block onto the rotating shaft. The metal clips on both sides of the rotating shaft can then engage in the slots on both sides of the connecting block. This design allows the stirring blade and connecting block to be quickly disassembled and installed on the rotating shaft, thereby enabling the surface of the stirring blade to be cleaned and preventing contamination during use.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 4An embodiment of this utility model provides a ractopamine fluorescence quantitative detection kit, including an outer fixation frame 1, a kit 2 inserted inside the outer fixation frame 1, a first storage cavity 7 provided on the upper side inside the kit 2, a stirring box 9 inserted inside the first storage cavity 7, a motor fixing cavity 12 provided at the bottom inside the stirring box 9, a micro motor 13 fixedly connected to the bottom inside the motor fixing cavity 12, a partition fixedly connected around the micro motor 13, the output end of the micro motor 13 extending through the partition to the upper side inside the stirring box 9, and multiple stirring blades 19 snapped onto the output end of the micro motor 13.

[0024] The output end of the micro motor 13 is connected to a rotating shaft 20 via a coupling. Metal clips 8 are fixedly connected to both sides of the rotating shaft 20. A connecting block 21 is clipped to the upper end of the rotating shaft 20. The cross-section of the connecting block 21 is designed as an inverted U-shaped structure. Both sides of the connecting block 21 are provided with clip grooves 22. The metal clips 8 on both sides of the rotating shaft 20 are clipped into the clip grooves 22. When the user turns on the switch of the micro motor 13, the rotating shaft on the micro motor 13 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the upper connecting block 21 and the stirring blade 19 to rotate, thereby making the stirring blade 19 mix and stir the liquid inside the stirring box 9.

[0025] After mixing is complete, the user pulls the connecting block 21 and the stirring blade 19 outwards, causing the entire connecting block 21 and stirring blade 19 to move outwards. Since the metal clip 8 is made of elastic metal material, the deformation of the metal clip 8 during the pulling of the connecting block 21 allows the entire connecting block 21 and the rotating shaft 20 to separate quickly. At this time, the user cleans the surface of the stirring blade 19, and then inserts the cleaned stirring blade 19 and connecting block 21 onto the rotating shaft 20. The metal clips 8 connected to both sides of the rotating shaft 20 can then be engaged in the engagement grooves 22 on both sides inside the connecting block 21. This design allows the entire stirring blade 19 and connecting block 21 to be quickly disassembled and installed on the rotating shaft 20, thereby enabling the surface of the stirring blade 19 to be cleaned and avoiding mixing contamination caused by use.

[0026] Fixed blocks 4 are fixedly connected to both sides of the bottom of the first storage cavity 7. The fixed blocks 4 have an inner cavity 14 inside. A through hole 17 is horizontally provided in the middle of the inner cavity 14. A movable column 6 is horizontally movably provided inside the through hole 17. A second movable plate 16 is fixedly connected to the upper and lower sides of one end of the movable column 6. A spring 15 is connected to one end of the second movable plate 16.

[0027] Both sides of the mixing box 9 are provided with fixing grooves 18. One end of the movable column 6 passes through the middle of the inner cavity 14 and is inserted into the fixing groove 18. The second movable plate 16 moves inside the inner cavity 14. One end face of the two second movable plates 16 and one end face of the inner cavity 14 are connected by springs 15. The stretching force of the springs 15 pushes the second movable plates 16 into the inner cavity 14, so that one end of the movable column 6 can be inserted into the fixing groove 18, thereby achieving the fixing function of the entire mixing box 9 inside the first storage cavity 7.

[0028] The lower side of the reagent kit 2 is provided with a second storage cavity 10, and the test strip 11 is placed inside the second storage cavity 10. The front and rear sides of the second storage cavity 10 are both secured with a first movable plate 5, and the upper end of the first storage cavity 7 is secured with an end cap 3.

[0029] During use, the fluorescein and the collected ractopamine antigen liquid need to be mixed and stirred during the preparation process. First, the fluorescein is poured into the stirring box 9 inside the first storage chamber 7. Then, the switch of the micro motor 13 is turned on. The rotating shaft on the micro motor 13 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the upper connecting block 21 and the stirring blade 19 to rotate. In this way, the stirring blade 19 mixes and stirs the fluorescein and the collected ractopamine antigen liquid inside the stirring box 9. The setting of micro motor 13, rotating shaft 20, connecting block 21 and stirring blade 19 replaces the existing manual stirring. This setting greatly improves the stirring efficiency.

[0030] After stirring, the user opens the first movable plates 5 on the front and rear sides of the second storage chamber 10, takes out the test strip 11 from the inside of the second storage chamber 10, and drops the fluorescein and the collected ractopamine antigen liquid onto the test strip 11, so that the test strip 11 displays the color of the fluorescein in the mixture, thereby determining the content of ractopamine antigen in the sampled liquid.

[0031] After the test strip 11 has finished testing the mixture, the user pulls the movable column 6 inside the fixing block 4, causing the movable column 6 to move the second movable plate 16 on the inner side laterally. As the second movable plate 16 moves laterally inside the inner cavity 14, it squeezes the spring 15, causing one end of the movable column 6 to disengage from the fixing groove 18. This completes the limiting and fixing of the two movable columns 6 on the mixing box 9, allowing the mixing box 9 to be removed from the first storage cavity 7. This makes it convenient for the user to clean the first storage cavity 7 and the inside of the mixing box 9.

[0032] After the entire interior of the mixing box 9 is cleaned, the mixing box 9 is inserted into the first storage cavity 7. Then, the second movable plate 16 inside the movable column 6 is affected by the stretching force of the spring 15. The second movable plate 16 drives the entire movable column 6 to move laterally inward, so that the movable column 6 can move into the fixing groove 18 on one side of the mixing box 9. Then, one end of the movable column 6 is directly inserted into the second movable plate 16. At this time, the two movable columns 6 engage with the mixing box 9, and finally the mixing box 9 is positioned inside the first storage cavity 7, in preparation for the next mixing and preparation of fluorescein and collected ractopamine antigen liquid.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
