Description

Technical Field

[0001] This invention relates to the field of veterinary drug testing equipment technology, and more specifically, to a convenient fluorescent quantitative detection device for veterinary drug residues. Background Technology

[0002] Veterinary drug residues refer to the accumulation or retention of the original drug or its metabolites in the bodies or products (such as eggs, dairy products, and meat products) of livestock and poultry after drug administration, including the residues of impurities related to veterinary drugs. They are generally measured in μg / ml or μg / g. With the shift in consumer demand for animal-derived foods from a demand-driven to a quality-driven approach, veterinary drug residues in animal-derived foods have gradually become a global focus.

[0003] A search revealed a Chinese patent, CN118275206B, which discloses a veterinary drug residue detection device and method, belonging to the field of detection equipment technology. It includes a mixing tank for holding animal tissue, with a feeding tube fixedly installed on the outside of the mixing tank for adding tissue processing reagents. This application utilizes a detection tank that slides inside the mixing tank. A crushing component at the bottom of the detection tank directly crushes the animal tissue inside the mixing tank. After crushing, the tissue is stirred inside the mixing tank to remove interfering components. After removing the interfering components, the tissue fluid inside the mixing tank can be directly extracted using pressure through the detection tank. This eliminates the need to transfer animal tissue and wait for tissue fluid extraction, solving the problem of reduced tissue fluid extraction efficiency caused by the need for transfer, impurity removal, and settling after crushing animal tissue, thus improving the efficiency of veterinary drug residue detection.

[0004] The inventors discovered that the above-mentioned technology, which involves mixing tissue fluid with detection reagents and then comparing it with a comparison card, relies on visual comparison, which is not accurate and is easily influenced by human subjectivity, resulting in inaccurate detection. Furthermore, after obtaining the tissue fluid, only a single test can be performed on that sample, and the detection data is unique and not precise enough. Therefore, this invention proposes a convenient fluorescent quantitative detection device for veterinary drug residues. Summary of the Invention

[0005] The purpose of this invention is to provide a convenient fluorescent quantitative detection device for veterinary drug residues, which can solve the problems mentioned in the background art.

[0006] The embodiments of the present invention are implemented as follows:

[0007] A portable fluorescent quantitative detection device for veterinary drug residues includes:

[0008] The base has four sets of support legs fixed at the bottom corner, and pulleys with foot brakes are installed under the support legs;

The shunt pipe is fixed above the fixing frame, and its ends extend through the fixing frame into the fixing seat. The top of the test tube is fitted onto the end of the shunt pipe.

[0018] As a further preferred embodiment of this technical solution, the part-retrieving assembly further includes three sets of filter screens fixed inside the filter sleeve from top to bottom, and the aperture of the three sets of filter screens increases sequentially from top to bottom. The top of the filter sleeve is machined with an internal thread, and the end of the input pipe is machined with an external thread. The filter sleeve is fitted onto the end of the input pipe through the internal and external threads, and a fixing member is fitted and fixed on the input pipe above the filter sleeve. The input pipe is fixed to the inner wall of the processing tank through the fixing member.

[0019] As a further preferred embodiment of this technical solution, the clamping assembly further includes four sets of wedges movably disposed on the side of the fixed base. The inner side of each wedge is connected to the inner wall of the fixed base by a spring, and a positioning rod is fixed to the side of each wedge. The end of the positioning rod is arc-shaped and contacts the side of the test tube.

[0020] As a further preferred embodiment of this technical solution, the bottom of the wedge block is integrally formed with an inclined surface, a ball is machined in the upper part of the inner part of the limiting ring, the ball is in contact with the inclined surface, a groove is machined on the side of the fixing seat, a slider is welded and fixed to the inner wall of the limiting ring, the slider is slidably connected to the inside of the groove, a thread matching the inner wall of the fixing ring is machined on the fixing seat outside the groove, the fixing ring is connected to the fixing seat through the thread, and the fixing ring is in contact with the bottom of the limiting ring.

[0021] As a further preferred embodiment of this technical solution, the light-shielding component includes a threaded rod rotatably connected inside the detection box. Two sets of guide rods are fixed inside the detection box on the front and rear sides of the threaded rod. A movable frame is welded and fixed to the lower left side of the baffle. The movable frame is slidably connected to the guide rod, and a threaded sleeve is fixed in the middle of the movable frame. The threaded sleeve is threadedly connected to the threaded rod. A movable motor is fixed to the right side of the detection box, and the output shaft of the movable motor is fixedly connected to the end of the threaded rod.

[0022] As a further preferred embodiment of this technical solution, the light-shielding assembly further includes two sets of fixing blocks welded and fixed inside the detection box on the right side of the test tube. A rotating rod is rotatably connected between the two sets of fixing blocks via a bearing.

[0024] The beneficial effects of the embodiments of the present invention are:

[0025] By combining the processing components with the sampling components, multiple sets of samples can be obtained in one preparation, which can then be used for multiple tests. This avoids insufficient data caused by testing a single sample, thus affecting the accuracy of the test.

[0026] The clamping components allow for quick installation of test tubes. The fixed ring pushes the limiting ring, causing the limiting ring to move upward. This pushes the wedge towards the fixed seat, which in turn causes the positioning rod to clamp the test tube, thus achieving positioning. The device is applicable to test tubes of different specifications within a certain range, thereby improving the flexibility of the equipment.

[0027] The light-shielding component, which uses a servo motor, can rotate the light-shielding base to store the test tubes and hide them with a baffle. This separates the test tubes and prevents the samples inside the test tubes from interfering with each other during the detection process, thus affecting the detection accuracy of the fiber optic probe.

[0028] Automatic detection is achieved by using a fiber optic probe in conjunction with a xenon lamp. The xenon lamp illuminates the fluorescent substances in the sample, and the fiber optic probe monitors the fluorescence time and intensity of the sample, transmitting the signal to the control panel for data analysis. This allows for the quantitative detection of veterinary drug residues in the sample, ensuring accuracy and avoiding errors caused by direct comparison using comparison cards.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] This invention provides a technical solution: such as Figures 1-10 As shown, in this embodiment, a convenient fluorescent quantitative detection device for veterinary drug residues includes:

[0048] Base 1, with four sets of support legs fixed at the bottom corner of base 1, and pulleys with foot brakes installed under the support legs;

[0049] The test box 2 has a cover 3 hinged to its right side, and a control panel 10 is fixed to the cover 3 by screws.

[0050] The processing component is located on the upper left side of the detection box 2. The processing mechanism includes a processing tank 4 fixed to the top of the detection box 2 by a support leg, and a sealing cover 5 is fixed to the top of the processing tank 4 by bolts.

[0051] The sampling assembly is located above the detection box 2 on the right side of the processing tank 4. The sampling assembly includes a pump body 9 fixed to the upper end of the detection box 2. An input pipe 16 is fixed to the input end of the pump body 9. The end of the input pipe 16 passes through the processing tank 4 and is threadedly connected to a filter sleeve 35.

[0052] The clamping assembly is located inside the detection box 2. The clamping assembly includes a fixing frame 18 fixed inside the detection box 2 by screws and four sets of fixing seats 28 fixed at equal intervals to the lower side of the fixing frame 18. Limiting rings 32 are fitted on the sides of the four sets of fixing seats 28, and fixing rings 30 are threadedly connected to the sides of the fixing seats 28 below the limiting rings 32.

[0053] The light-shielding component is located inside the detection box 2. The light-shielding component includes a baffle 19 that is movably located inside the detection box 2 and a light-shielding seat 25 that is rotatably located inside the detection box 2. The baffle 19 is located on the left side of the fixing frame 18 and the light-shielding seat 25 is located on the right side of the fixing frame 18.

[0054] The detection assembly is located inside the detection chamber 2. The detection assembly includes four sets of test tubes 31 installed inside the mounting base 28, four sets of fiber optic probes 20 fixed inside the baffle 19, and a xenon lamp 26 fixed inside the chamber cover 3. The four sets of fiber optic probes 20 are located directly to the left of the four sets of test tubes 31, and the fiber optic probes 20 and the xenon lamp 26 are electrically connected to the control panel 10.

[0055] like Figure 1 and Figure 2 As shown, a power supply box 15 is fixed on the base 1 at the rear of the test box 2. The power supply box 15 contains a battery for power supply, and a push rod is welded and fixed on the base 1 at the rear of the power supply box 15. The battery (not shown) inside the power supply box 15 can supply power to the equipment, avoiding the trouble caused by an external power supply. The push rod can be used in conjunction with the pulleys of the base 1 to move the equipment, making it convenient to carry and transport.

[0056] like Figure 1 and Figure 2 As shown, the processing assembly also includes a stirring motor 7 fixed to the top of the sealing cover 5, and a feed pipe is fixed to the sealing cover 5 on the left side of the stirring motor 7. It should be noted that a crushing rod (not shown) is fixed to the output shaft of the stirring motor 7. The crushing rod is inserted into the processing tank 4. Since the filter sleeve 35 and the input pipe 16 are fixed to the inner wall of the processing tank 4, the crushing rod can be prevented from contacting them during rotation and causing damage. The top of the processing tank 4 and the lower side of the sealing cover 5 are integrally formed with a pressing edge. The two sets of pressing edges are fixedly connected by bolts. A drain pipe 6 is fixed to the lower left side of the processing tank 4, and a valve is installed on the drain pipe 6. The pressing edge facilitates the installation of bolts, which in turn facilitates the subsequent opening of the sealing cover 5 to clean the inside of the processing tank 4. The sample inside the processing tank 4 can be discharged through the drain pipe 6.

[0057] like Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 8As shown, the sampling assembly also includes an output pipe 8 fixed to the output end of the pump body 9. The end of the output pipe 8 extends through the detection box 2 and is fixed with a diverter pipe 27. The diverter pipe 27 is fixed above the mounting bracket 18, and its ends extend through the mounting bracket 18 to the inside of the mounting base 28. The top of the test tube 31 is fitted onto the end of the diverter pipe 27. The sampling assembly also includes three sets of filter screens 34 fixed from top to bottom inside the filter sleeve 35. The aperture of the three sets of filter screens 34 increases sequentially from top to bottom. The top of the filter sleeve 35 is machined with an internal thread, and the end of the input pipe 16 is machined with an external thread. The filter sleeve 35 is fitted onto the end of the input pipe 16 through the internal and external threads. A fixing member 33 is fitted and fixed on the input pipe 16 above the filter sleeve 35. The input pipe 16 is fixed to the inner wall of the processing tank 4 by the fastener 33. The output pipe 8 facilitates the pump body 9 to deliver the prepared tissue fluid to the inside of the diversion pipe 27. The diversion pipe 27 can introduce the tissue fluid into the test tube 31, so that multiple sets of test samples can be obtained at one time. It should be noted that in order to ensure that the volume of tissue fluid inside the test tube 31 is consistent, a flow meter can be installed at the end of the diversion pipe 27. The tissue fluid can be filtered by the three sets of filters 34 from top to bottom inside the filter sleeve 35 when the pump body 9 draws it, which can avoid the need to wait for sedimentation. The filter sleeve 35 can be disassembled periodically to rinse the internal filter screens 34 through the threads machined on the input pipe 16 and the filter sleeve 35.

[0058] like Figure 3 , Figure 4 , Figure 5 , Figure 9 as well as Figure 10As shown, the clamping assembly also includes four sets of wedges 29 movably disposed on the side of the fixed base 28. The inner side of the wedges 29 is connected to the inner wall of the fixed base 28 by springs 40, and a positioning rod 39 is fixed to the side of the wedges 29. The end of the positioning rod 39 is arc-shaped and contacts the side of the test tube 31. The bottom of the wedges 29 is integrally formed with an inclined surface. A ball is machined in the upper part of the limiting ring 32 and contacts the inclined surface. A groove is machined on the side of the fixed base 28. A slider is welded and fixed to the inner wall of the limiting ring 32 and slides inside the groove. The slider is slidably connected to the inside of the groove. A matching thread is machined on the inner wall of the fixing ring 30 on the fixed base 28 outside the groove. The fixing ring 30 is connected to the fixed base 28 by the thread and contacts the bottom of the limiting ring 32. By connecting the wedges 29 to the fixed base 28 using springs 40, the wedges 29 can be reset when the limiting ring 32 is separated from the wedges 29. This design allows the positioning rod 39 to separate from the test tube 31. The arc-shaped design of the positioning rod 39 facilitates contact with the side of the test tube 31. The inclined surface at the bottom of the wedge block 29 allows it to move towards the interior of the fixed seat 28 when the limiting ring 32 moves upward, thereby moving the positioning rod 39 to clamp the test tube 31. The ball bearings on the limiting ring 32 reduce wear between the limiting ring 32 and the wedge block 29. The slider and groove allow the limiting ring 32 to move, preventing it from easily rotating axially on the fixed seat 28. The threaded connection between the fixed ring 30 and the fixed seat 28 allows the fixed ring 30 to move when rotated, thereby moving the limiting ring 32 upward and providing support, thus limiting the wedge block 29 and facilitating clamping of the test tube 31. This design is suitable for test tubes 31 of certain specifications.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 6 as well as Figure 7As shown, the light-shielding assembly includes a threaded rod 23 rotatably connected inside the test chamber 2. Two sets of guide rods 22 are fixed inside the test chamber 2 on the front and rear sides of the threaded rod 23. A movable frame 21 is welded and fixed to the lower left side of the baffle 19. The movable frame 21 is slidably connected to the guide rods 22, and a threaded sleeve is fixed in the middle of the movable frame 21. The threaded sleeve is threadedly connected to the threaded rod 23. A movable motor 17 is fixed to the right side of the test chamber 2. The output shaft of the movable motor 17 is fixedly connected to the end of the threaded rod 23. The light-shielding assembly also includes a test chamber 2... Two sets of fixing blocks 24 are located inside the detection box 2 on the right side of tube 31. A rotating rod 37 is rotatably connected between the two sets of fixing blocks 24 via bearings. A connector 38 is fixedly fitted to the end of the rotating rod 37, and the other end of the connector 38 is welded to the side of the light shield 25. A servo motor 13 is fixed to the front of the detection box 2 via a bracket 14. A drive gear 11 is fixedly fitted on the rear output shaft of the servo motor 13. The front part of the rotating rod 37 extends to the front of the detection box 2 and is fitted with a driven gear 12. The drive gear 11 and the driven gear 12 mesh with each other. The light-shielding base 25 has three sets of partitions 36 integrally formed inside. A first notch is integrally formed on the right side of the light-shielding base 25. The baffle 19 has an L-shaped cross-section in side view and a second notch integrally formed on its top. The moving motor 17 drives the threaded rod 23 to rotate, which in turn engages with the threaded sleeve on the moving frame 21. The guide rod 22 limits the movement of the moving frame 21, allowing it to move left and right reciprocally. This facilitates the movement of the baffle 19, enabling it to engage with the light-shielding base 25. Adjacent test tubes 31 are separated to avoid mutual interference. The servo motor 13 drives the drive gear 11 to rotate, which in turn drives the driven gear 12 to rotate. This causes the rotating rod 37 to drive the light shield 25 to rotate. When the rotation is vertical, the test tubes 31 can be hidden. The rotation of the light shield 25 does not affect the illumination of the xenon lamp 26. The baffle 19 and the light shield 25 separate the test tubes 31, making it convenient for each group of fiber optic probes 20 to detect the samples in the corresponding test tubes 31.

[0060] This invention provides a convenient fluorescent quantitative detection device for veterinary drug residues. The specific working principle is as follows: During normal use, the device is first moved to the designated location using pulleys and then connected to power. The device data is adjusted via the control panel 10. Samples and reagents are added to the processing tank 4. The stirring motor 7 drives the internal pulverizing rod to rotate, stirring and pulverizing the sample. After mixing, the pump 9 extracts the tissue fluid. The fluid is filtered through the filter screen 34 inside the filter sleeve 35 during extraction. The pump 9 delivers the tissue fluid through the output pipe 8 to the split pipe 27 and then into the test tube 31, obtaining multiple sets of test samples. Extraction is then stopped. The control panel 10 controls the xenon lamp to run for a specified time. At this time, the light shield 25 is in a horizontal position, not affecting the irradiation of the tissue fluid in the test tube 31 by the xenon lamp. After irradiation, the fluorescent substance in the tissue fluid emits light, and the servo motor 1... 3. The driving gear 11 rotates, which in turn drives the driven gear 12 to rotate the rotating rod 37. The rotating rod 37 drives the light-shielding seat 25 to rotate through the connecting piece 38 until the light-shielding seat 25 is vertical. At this time, the test tube 31 is located inside the light-shielding seat 25. Then, the moving motor 17 is run, which drives the threaded rod 23 to rotate. The moving frame 21 drives the baffle 19 to move until the baffle 19 is in contact with the light-shielding seat 25, thereby separating the test tubes 31. At this time, the corresponding fiber optic probe 20 on the inner side of the baffle 19 is used to detect the fluorescence brightness and time emitted by the fluorescent substance in the corresponding test tube 31. Since the baffle 19, together with the partition 36 and the light-shielding seat 25, separates the test tubes 31, the detection data of each fiber optic probe 20 does not affect each other and is transmitted to the control panel 10 for display, thereby achieving quantitative and rapid detection and ensuring the accuracy of the detection.

[0061] When test tube 31 needs to be disassembled, the operator opens the box cover 3 and rotates the fixing ring 30 in sequence. The fixing ring 30 moves downward, and the limiting ring 32 also moves downward. At this time, the wedge 29 moves outward under the force of the spring 40. The wedge 29 drives the positioning rod 39 to move, and the positioning rod 39 separates from the test tube 31. The operator can then remove the test tube 31. This process can be repeated to facilitate replacement. It should be noted that the electronic components used in this technical solution are all existing products. The technical solution of this application does not have any special requirements or changes to the structure of the above-mentioned electronic components. During the implementation of this technical solution, those skilled in the art need to connect all electrical components and their compatible power supplies through wires. They should also select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle of this technical solution and the sequential working sequence of each electrical component. The detailed connection methods are well-known in the art. This technical solution mainly introduces the working principle and process, and will not describe the electrical control further.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
