Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material fungus detection, in particular to a fluorescent immunochromatographic test paper detection device for Chinese medicinal material fungal toxins. Background Art

[0002] The fluorescent immunochromatographic test strip detection device for mycotoxins in traditional Chinese medicine is an instrument specially used to detect whether traditional Chinese medicine contains mycotoxins. It is based on the specific immune reaction of antigen and antibody. The mycotoxins in the sample are first allowed to bind to the antigens labeled with fluorescent microspheres on the test strip. The test strip is then placed in the card insertion hole of the detection device. The fluorescent signal is stimulated by the light source of the detection device, and the signal is analyzed to obtain the test result.

[0003] However, the optical system of the existing detection device (such as the excitation light source and the fluorescence signal collection component) is usually precisely designed and calibrated according to the detection area of ​​a test strip. A single card slot has only one test strip in the detection light path at a time. When a large number of Chinese herbal medicine samples need to be tested for mycotoxins, the staff needs to insert the samples into the card slot one by one. Therefore, manual insertion and removal operations are required frequently. The manual operation speed is relatively slow, and the staff is prone to fatigue during long-term repeated operations, further reducing the detection speed. To this end, a fluorescent immunochromatographic test strip detection device for Chinese herbal medicine mycotoxins is proposed. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By transmitting the test strips that have been tested and those to be tested one by one, the test strips that have been tested can be automatically pulled out of the card insertion hole, and the test strips to be tested can be automatically inserted into the card insertion hole for testing, thus realizing seamless connection of the mycotoxin testing process of Chinese medicinal materials.

When facing a large number of Chinese medicinal materials samples, the testing can be completed quickly in sequence, which significantly improves the overall throughput of mycotoxin testing of Chinese medicinal materials, so that the testing work can be completed in a shorter time, meeting the needs of batch testing.

[0017] The staff only needs to place the test strip to be tested in the designated position without directly touching the card insertion hole and performing complicated plug-in and pull-out operations, which reduces the difficulty of operation and labor intensity, and can avoid manual errors caused by fatigue, unskilled operation or negligence when replacing the test strip, improve the convenience and safety of operation, and can always ensure that the test strip is accurately inserted into the card insertion hole, thereby improving the accuracy and reliability of the test results of Chinese herbal medicine fungal toxins;

[0018] When the test strip is inserted into the card insertion hole, the raised end of the cam contacts the push plate 1, so that the test strip inside the card insertion hole is pressed by the cam in the direction of the card insertion hole. The continuous pressure can ensure that the test strip will not be displaced in the card insertion hole due to external interference, so that the test strip can always be kept in an accurate detection position, and maintain a stable relative position relationship with the excitation light source and the fluorescent signal collection component inside the detection device, thereby ensuring the consistency of the detection light path, which is conducive to improving the accuracy of the detection results of mycotoxins in traditional Chinese medicines;

[0019] The test strips that have passed the test are separated by the card return plate and fall into the discarded card box, which effectively avoids the contact between the tested test strips and the new test strips, prevents the spread of fungal toxins between different samples and between different test strips, and significantly reduces the possibility of cross-contamination, ensuring that each test is independent and pollution-free, thereby providing accurate data basis for the detection of fungal toxins in traditional Chinese medicines and avoiding misjudgment due to cross-contamination;

[0020] Through the continuous transmission of the belt, the long rod suction cup separated from the test strip is transmitted to the staff loading position on the right side of the belt, so that the staff only needs to place the new test strip to be tested at a specific loading position, without having to participate in the complicated removal and sorting of the test strips, which simplifies the operation process and reduces the work intensity and operation difficulty of the staff;

[0021] By disinfecting the card insertion hole during the time between the completion of the test and the switching of the test strip to be tested, residual mycotoxins, impurities and microorganisms from the previous test can be removed to prevent these residual substances from contaminating the next test strip to be tested, ensuring that each time the detection device detects mycotoxins in traditional Chinese medicines, it is based on a pure and interference-free environment, thereby significantly improving the accuracy and reliability of the detection results of mycotoxins in traditional Chinese medicines.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiments provided by the present invention:

[0040] Embodiment 1:

[0041] See also Figures 1 to 12As shown, a fluorescent immunochromatographic test strip detection device for mycotoxin in traditional Chinese medicine comprises a detection device 11, a card insertion hole 12 and a plurality of test strips 13, wherein the card insertion hole 12 is arranged on the detection device 11, and an advance and retreat component is arranged on the detection device 11, and the advance and retreat component comprises four rotating columns 21, and the four rotating columns 21 are rotatably connected to a side of the detection device 11 close to the card insertion hole 12, and a belt 22 is commonly connected to the four rotating columns 21 for transmission, and a plurality of telescopic tubes 23 are connected to the side wall of the belt 22 in a rectangular array, and a plurality of The ends of the telescopic tubes 23 away from the belt 22 are each fixedly connected with a push plate 24. The interiors of the multiple telescopic tubes 23 are hollow. A spring 25 is disposed inside each of the multiple telescopic tubes 23. The two ends of the spring 25 are respectively fixedly connected to the belt 22 and the corresponding push plate 24. The sides of the multiple push plates 24 close to the telescopic tubes 23 are each fixedly connected with two long rod suction cups 26. The long rod suction cups 26 are electric vacuum suction cups. The side of the detection device 11 close to the belt 22 is fixedly connected with a support rod 27. The end of the support rod 1 27 away from the detection device 11 is fixedly connected to the micro motor 28, and the output shaft of the micro motor 28 is fixedly connected to the cam 29. The side of the cam 29 away from the micro motor 28 is fixedly connected to the half gear 210. The side of the detection device 11 close to the half gear 210 is fixedly connected to the support rod 211. The end of the support rod 211 away from the detection device 11 is rotatably connected to the rotating shaft 212. The end of the rotating shaft 212 close to the half gear 210 is fixedly connected to the side gear 213. The rotating shaft 212 is far away from the detection device 11. One end of the side gear 213 is fixedly connected to a bevel gear 1 214, a connecting rod 216 is fixedly connected to a rotating column 21 on the side close to the cam 29, and the end of the connecting rod 216 away from the rotating column 21 is fixedly connected to a bevel gear 215, a card discarding box 217 is fixedly connected to the bottom of the detection device 11 close to the rotating column 21, a card ejection plate 218 is fixedly connected to the bottom of the inner wall of the card discarding box 217, an inner support plate 219 is fixedly connected to the detection device 11, and an outer support plate 220 is fixedly connected to the top of the inner wall of the card discarding box 217.

[0042] Among them: Reference Figure 5 As shown, the inner support plate 219 and the outer support plate 220 are both arranged in a ring shape, and the outer ring surface of the inner support plate 219 is in contact with and fits with the multiple telescopic tubes 23, and the inner ring surface of the outer support plate 220 is in contact with and fits with the multiple telescopic tubes 23. Specifically, the inner ring surface of the outer support plate 220 and the outer ring surface of the inner support plate 219 can limit the moving path of the multiple telescopic tubes 23, and at the same time prevent the outer ring surface of the belt 22 from being subjected to fatigue deformation due to long-term stress.

[0043] Wherein: when in use, the test strip 13 is fixed by the long rod suction cup 26 through low pressure adsorption, and the test strip 13 is fixed to the push plate 1 24 through the long rod suction cup 26, and the end of the push plate 1 24 close to the telescopic tube 1 23 is set as an arc surface.

[0044] The side gear 213 meshes with the half gear 210 , and the number of teeth of the side gear 213 is equal to the number of teeth of the half gear 210 , that is, the half gear 210 rotates half a circle to drive the side gear 213 to rotate one circle, and the bevel gear 1 214 and the bevel gear 2 215 mesh with each other.

[0045] Among them: there is an electrical connection between the micro motor 28 and the detection device 11 through the controller, that is, when the detection device 11 completes a detection, it is necessary to pull out the test strip 13 that has completed the detection from the inside of the card insertion hole 12, and when a new test strip 13 is inserted into the inside of the card insertion hole 12, the micro motor 28 receives the electrical signal and its output shaft rotates one circle.

[0046] Among them: Figure 7 , Fig.10 In the example of the position relationship, the output shaft of the micro motor 28 rotates counterclockwise, that is, the cam 29 and the half gear 210 both rotate counterclockwise, the half gear 210 engages to drive the side gear 213 to rotate clockwise, and the bevel gear 1 214 rotates in the same direction as the side gear 213 through the rotating shaft 212, that is, the bevel gear 1 214 drives the bevel gear 2 215 to rotate counterclockwise. Specifically: when the output shaft of the micro motor 28 rotates, the rotating column 21 rotates one circle counterclockwise.

[0047] The distance of one rotation of the four rotating columns 21 is equal to the distance between two adjacent push plates 24. Fig.12 It is a position example, that is, the rotating column 21 rotates one circle, and the test strip 13 located on the right side of the top of the belt 22 advances one position to the left.

[0048] The top of the card ejection plate 218 is set as an inclined surface, and the top of the card ejection plate 218 is located on the moving path of the plurality of long-rod suction cups 26 , specifically on the moving path of the long-rod suction cups 26 and the adsorption position of the test strip 13 .

[0049] When the feeding and withdrawing components are running, Figure 1 The state shown in the figure is that the test strips 13 are adsorbed on the top of the belt 22 and the long rod suction cup 26 on the left side, and a test strip 13 is inserted into the card insertion hole 12. The detection device 11 detects the test strip 13 inside the card insertion hole 12. The detection device 11 excites the light source to excite the fluorescent signal of the test strip 13, analyzes the signal and obtains the detection result. The cam 29 rotates until its protruding end contacts the push plate 24 located at the card insertion hole 12, and the spring 25 at the card insertion hole 12 is in an elastically contracted state. The half gear 210 is not engaged with the side gear 213. Figure 1 As shown, at this time, the staff sucks the test strip 13 to be tested onto the long rod suction cup 26 located on the right side of the belt 22.

[0050] When the detection device 11 completes the detection of the test strip 13 inside the card insertion hole 12, at this time, the micro motor 28 receives the electrical signal and its output shaft rotates one circle counterclockwise, and the output shaft of the micro motor 28 drives the cam 29 to rotate one circle counterclockwise synchronously, that is, the raised end of the cam 29 rotates toward the top of the detection device 11 at this time, and when the cam 29 rotates to the state, the raised end of the cam 29 no longer squeezes the push plate 24 at the position of the card insertion hole 12, and under the elastic extension action of the spring 25, the output end of the telescopic tube 23 is extended, and then the telescopic tube 23 drives the test strip 13 to move away from the detection device 11 through the push plate 24, so that the test strip 13 located inside the card insertion hole 12 is separated from the inside of the card insertion hole 12.

[0051] like Figure 7 , Figure 8 As shown, when the cam 29 rotates to the vertical state, the half gear 210 is meshed with the side gear 213, and then as the cam 29 continues to rotate counterclockwise, the half gear 210 meshes and drives the side gear 213 to rotate clockwise. Combined with the above, at this time, the bevel gear 215 drives the rotating column 21 to rotate one circle counterclockwise through the connecting rod 216, that is, at this time, the belt 22 drives the rotating column 21 counterclockwise for a distance of one circle of the circumference, specifically, the length between two adjacent push plates 24 driven counterclockwise by the belt 22, so that the tested test strip 13 is driven counterclockwise, and the test strip 13 to be tested that was previously located on the right side of the belt 22 is driven counterclockwise. At this time, the test strip 13 to be tested is located at the card insertion hole 12. At this time, the cam 29 rotates to the position where the protruding end faces downward, and the tooth surface of the half gear 210 faces the detection device 1 1 side, with the continuous rotation of the cam 29, specifically: the raised end of the cam 29 rotates upward toward the detection device 11, at this time, the half gear 210 rotates until it is no longer engaged with the side gear 213, and at the same time, during the rotation of the cam 29 toward the detection device 11, the raised end of the cam 29 contacts the push plate 124 corresponding to the test paper strip 13 to be detected, so that the push plate 124 moves toward the detection device 11, and elastically compresses the spring 125, so that the push plate 124 pushes the test paper strip 13 into the inside of the card insertion hole 12 through the long rod suction cup 26. At this time, the test paper strip 13 enters the inside of the card insertion hole 12 for detection, and the rotating column 21 no longer rotates, that is, the corresponding telescopic tube 123, the push plate 124 and the long rod suction cup 26 remain stationary, specifically: the positional relationship between the test paper strip 13 and the card insertion hole 12 remains stationary.

[0052] In this reciprocating manner, the test strips 13 that have been tested and those to be tested can be driven counterclockwise one by one. When the test strips 13 that have been tested are driven to the bottom of the belt 22, as the belt 22 continues to drive, the inclined surface of the card ejection plate 218 contacts the position between the test strips 13 that have been driven here and the long rod suction cup 26, and shovels the test strips 13 and the long rod suction cup 26 apart. The separated test strips 13 that have been tested fall into the discarded card box 217 under the action of gravity.

[0053] In the above process, by transmitting the test strips 13 that have been tested and those to be tested one by one, the test strips 13 that have been tested can be automatically pulled out of the card insertion hole 12, and the test strips 13 to be tested can be automatically inserted into the card insertion hole 12 for testing, thereby achieving a seamless connection of the Chinese medicinal materials mycotoxin testing process. There is no need to manually replace the test strips 13, which effectively reduces the interval time between the tests of each test strip 13. When faced with a large number of Chinese medicinal materials samples, the tests can be completed quickly and one by one, which significantly improves the overall Chinese medicinal materials mycotoxin testing throughput, enables the testing work to be completed in a shorter time, and meets the needs of batch testing.

[0054] The staff only needs to place the test strip 13 to be tested at the designated position without directly contacting the card insertion hole 12 and performing complicated plugging and unplugging operations, thereby reducing the difficulty of operation and labor intensity, and avoiding manual errors caused by fatigue, unskilled operation or negligence when replacing the test strip 13, thereby improving the convenience and safety of operation, and being able to always ensure that the test strip 13 is accurately inserted into the card insertion hole 12, thereby improving the accuracy and reliability of the detection results of mycotoxins in traditional Chinese medicines.

[0055] When the test strip 13 is inserted into the card insertion hole 12, the raised end of the cam 29 abuts against the push plate 24, so that the test strip 13 inside the card insertion hole 12 is exerted with pressure in the direction of the card insertion hole 12 by the cam 29. The continuous pressure can ensure that the test strip 13 will not be displaced in the card insertion hole 12 due to external interference, so that the test strip 13 can always be kept in an accurate detection position, and maintain a stable relative position relationship with the excitation light source and the fluorescent signal collection component inside the detection device 11, thereby ensuring the consistency of the detection light path, which is beneficial to improving the accuracy of the detection results of mycotoxins in traditional Chinese medicine.

[0056] At the same time, the test strip 13 inside the card insertion hole 12 is pressed toward the card insertion hole 12 by the cam 29, so that the signal transmission contacts or other functional components between the test strip 13 and the inside of the card insertion hole 12 are in close contact, thereby avoiding unstable or interrupted signal transmission due to poor contact, and ensuring the complete and accurate collection of the mycotoxin detection data of traditional Chinese medicine.

[0057] At the same time, the test strips 13 that have passed the test are separated by the card return plate 218 and fall into the discarded card box 217, which effectively avoids the contact between the tested test strips 13 and the new test strips 13, prevents the spread of fungal toxins between different samples between different test strips 13, and significantly reduces the possibility of cross-contamination, ensuring that each test is independent and pollution-free, thereby providing accurate data basis for the detection of fungal toxins in traditional Chinese medicines and avoiding misjudgment due to cross-contamination.

[0058] At the same time, as the belt 22 continues to drive, the long rod suction cup 26 detached from the test strip 13 is transmitted to the staff loading position on the right side of the belt 22, so that the staff only needs to place the new test strip 13 to be tested at the specific loading position, without having to participate in the complicated removal and sorting of the test strips 13, which simplifies the operation process and reduces the work intensity and operation difficulty of the staff.

[0059] Embodiment 2:

[0060] There are many kinds of mycotoxins in existing Chinese medicinal materials, and the toxin components and contents in different samples may be different. The existing detection device 11 does not have the function of disinfecting the card insertion hole 12 after each test of the test strip 13. When a test strip 13 containing a high concentration of mycotoxins is tested, toxins may remain in the card insertion hole 12. When the test strip 13 of the next sample is inserted, it may be contaminated with these residual toxins, causing interference with the test results, thereby reducing the accuracy of the test.

[0061] Reference Figures 9 to 11 As shown, a disinfection component is provided on the detection device 11, and the disinfection component is used to disinfect the card insertion hole 12 during the time when different test strips 13 are switched for insertion and removal. The disinfection component includes a telescopic tube 2 31, which is fixedly connected to the side of the detection device 11 close to the card insertion hole 12, and the end of the telescopic tube 2 31 away from the detection device 11 is fixedly connected to a disinfection box 32, the interior of the telescopic tube 2 31 is set to be hollow, and a spring 2 33 is provided inside the telescopic tube 2 31, and the two ends of the spring 2 33 are respectively fixedly connected to the detection device 11 and the disinfection box 32, and the outer wall of the disinfection box 32 away from the detection device 11 is fixedly connected to a push plate 2 34, and a filling port is provided on the top surface of the disinfection box 32, and a filling cap 35 is clamped in the filling port of the disinfection box 32, and a pump rod 36 is inserted on the side of the disinfection box 32 close to the detection device 11, and the end of the pump rod 36 close to the detection device 11 is fixedly connected to a through pipe 37, and the side of the detection device 11 close to the card insertion hole 12 is fixedly connected to a nozzle 38.

[0062] Among them: Reference Fig.11 As shown, the nozzle 38 is sleeved on the outside of the card insertion hole 12, the nozzle 38 is connected to the inside of the through pipe 37, and the side of the nozzle 38 close to the card insertion hole 12 is set as an atomizing spray hole oblique to the card insertion hole 12.

[0063] Among them: Reference Fig.10 As shown, the push plate 2 34 is configured to be arc-shaped and is located on the rotation path of the cam 29 . Specifically, the rotation of the cam 29 can push the push plate 24 toward the detection device 11 .

[0064] When not in use, the staff can pull out the filling cap 35 and inject disinfectant into the disinfection box 32 through the filling port. It should be noted that the disinfectant has the characteristic of quick drying.

[0065] When the disinfection component is running, the material feed and retract component is in operation, specifically: the cam 29 rotates to the point where the protruding end faces downward. Combined with what is known above, at this time, the test strip 13 is not inserted into the card insertion hole 12, and the tested test strip 13 is in the process of being transferred and the test strip 13 to be tested is being transferred toward the card insertion hole 12.

[0066] As the cam 29 continues to rotate, the raised end of the cam 29 rotates upward toward the detection device 11. During this process, the cam 29 pushes the push plate 2 34 toward the detection device 11, so that the spring 2 33 is elastically compressed. At the same time, the filling cap 35 moves synchronously toward the pump rod 36, and then the pump rod 36 pumps out disinfectant from the inside of the disinfection box 32. The disinfectant flows into the inside of the nozzle 38 through the through pipe 37. At this time, the disinfectant is sprayed into the inside of the card insertion hole 12 through the atomizing nozzle on the nozzle 38, so that the inside of the card insertion hole 12 is disinfected. Subsequently, when the cam 29 rotates to a position where it no longer conflicts with the push plate 2 34, under the elastic extension of the spring 2 33, the push plate 2 34 and the disinfection box 32 move away from the detection device 11. At this time, the pump rod 36 no longer pumps out disinfectant from the inside of the disinfection box 32. When the cam 29 rotates to Fig.10 When the test strip 13 to be tested is in the position shown in FIG. 1 , the test strip 13 to be tested is inserted into the sterilized card insertion hole 12 .

[0067] By disinfecting the card insertion hole 12 during the time between the completion of the test and the switching of the test strip 13 to be tested, the residual mycotoxins, impurities and microorganisms from the previous test can be removed to prevent these residual substances from contaminating the next test strip 13 to be tested, ensuring that each time the detection device 11 detects the mycotoxins of traditional Chinese medicines, it is based on a pure and interference-free environment, thereby significantly improving the accuracy and reliability of the detection results of mycotoxins of traditional Chinese medicines.
