Description

Technical Field

[0001] The present invention relates to the technical field of immunoassay, and particularly to a rapid detection kit for food allergens. Background Art

[0002] Food allergens refer to antigenic substances contained in foods that can induce allergic reactions in the human or animal body. They are foreign macromolecules that the immune system cannot recognize, mainly proteins or glycoproteins, with a molecular weight of about 10 - 80 kDa, and contain multiple epitopes (antigenic determinants) that can bind to IgE antibodies. They are usually also referred to as sensitizers or allergens. Currently, the main methods for determining allergens are intradermal tests and prick tests. These methods can generally obtain test results within half an hour and have the advantages of simplicity, rapidity, and low cost. However, the disadvantages are high false positives and being greatly affected by other drugs. Taking anti-allergy drugs within 24 hours before the test will affect the test results, and even for patients with severe allergic reactions, skin tests may pose a certain risk to life.

[0003] In the prior art, the types of allergens are also detected through in vitro experiments. For example, by extracting a small amount of serum and then using the enzyme-linked immunosorbent assay (ELISA) to detect the content of specific IgG produced against certain allergens in the sample to complete allergen screening and the detection of specific allergens; such as a rapid detection kit for food allergens with the publication number CN214703654U, which can rapidly detect food allergens, including: a box body and a test strip arranged inside the box body; the test strip sequentially includes, according to the flow direction of the sample to be tested: a sample pad for dropping the sample to be tested, a quenching antibody binding pad, a membrane strip for detecting the sample to be tested, and a blotting paper; the quenching antibody binding pad is provided with a fluorescently labeled antibody or antigen; the membrane strip serves as a carrier for the test line and the quality control line and is the place where the immune reaction occurs. Different food allergens are coated in the test line; the test strip is sequentially arranged with adjacent sample pads, quenching antibody binding pads, and membrane strips in a continuous amplification manner.

[0004] However, when using the kits of the prior art, they need to be placed horizontally on the desktop, and then the collected liquid is dropped onto the dropper hole on the kit. The liquid extends into the test paper through the dropper hole, and the allergen can be known by observing the color reaction on the test paper; however, the disadvantage of the kits of the prior art is that they are prone to sliding or falling when placed on the desktop, which will affect the test results, and the kits are packaged in a packaging bag. When the packaging bag is opened and not used, the kit will deteriorate if not used for a long time, which will cause waste of the kit; for this reason, the present application proposes a rapid detection kit for food allergens. Summary of the Invention

[0005] The object of the present invention is to solve the above technical problems and propose a rapid detection kit for food allergens.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A rapid detection kit for food allergens, comprising a kit, on which a plurality of test paper slots are provided, detection test papers are placed in the test paper slots, a strip-shaped slot is provided above the test paper slots on the kit, a liquid dropping hole is provided through the inner bottom of the strip-shaped slot, the liquid dropping hole is arranged opposite to the test paper and communicated with the test paper slot, and it is characterized in that: A sliding slot and a sealing slot are provided oppositely in the strip-shaped slot, a sealing plate is slidably connected in the sliding slot, a plurality of first springs are provided between the sealing plate and the sliding slot, and the sealing plate extends into the sealing slot to seal and block the strip-shaped slot; A circular slot is provided on the inner wall of the sliding slot, a piston connected to the sealing plate is slidably connected in the circular slot, a limiting rod is fixedly connected to the piston, an inner cavity and a vertical cavity are provided in the kit, the inner cavity is communicated with the circular slot through a pipeline located in the kit, a plurality of rubber suction cups communicated with the inner cavity are installed at the bottom of the kit, a driving member penetrating through the bottom of the kit is arranged in the inner cavity, a baffle is slidably connected in the vertical cavity, when the kit is placed on a tabletop and the driving member is displaced, the rubber suction cups can adsorb on the tabletop before the sealing plate can be opened, and when the driving member is displaced and the rubber suction cups cannot adsorb on the contact surface, the sealing plate cannot be opened.

[0007] Preferably, a connecting rod is fixedly connected to the piston, a guiding ring is fixedly connected in the circular slot, the connecting rod penetrates through the guiding ring and is slidably connected therewith, the connecting rod is fixedly connected to the sealing plate, and a second spring is fixed between the piston and the circular slot.

[0008] Preferably, the limiting rod penetrates through the kit and is slidably arranged thereon, and a removable circular block is provided on the kit, and the circular block is arranged opposite to the limiting rod.

[0009] Preferably, the driving member includes a rectangular rod penetrating through the bottom of the kit and slidably arranged thereon, a rack plate is fixedly connected to the upper end of the rectangular rod, a blocking block is fixedly connected to the rack plate, the blocking block can seal the pipeline, an air hole opposite to the pipeline is provided through the blocking block, a transmission rod is arranged in the inner cavity, the transmission rod penetrates through the kit and is rotatably connected therewith, the other end of the transmission rod extends into the vertical cavity, and a gear is fixed on the transmission rod, and the gear meshes with the rack plate.

[0010] Preferably, a reset mechanism is further included, and the reset mechanism includes a cross block fixed on the blocking block, a third spring is fixedly connected to the bottom of the cross block, and the other end of the third spring is fixedly connected to the inner wall of the inner cavity.

[0011] Preferably, it further includes a driving mechanism capable of driving the baffle to move up and down. The driving mechanism includes a circular plate fixed on the transmission rod. A connecting rod is eccentrically hinged to the circular plate, and the other end of the connecting rod is hinged to the baffle. A guide plate is fixedly connected in the vertical cavity, and the baffle penetrates through the guide plate and is slidably connected thereto.

[0012] Preferably, a limiting hole is penetrated through the baffle, and the limiting rod can extend into the limiting hole to limit the baffle.

[0013] Preferably, an exhaust hole communicating with the circular groove is penetrated through the upper end of the kit, and the exhaust hole is located between the baffle and the piston.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. If the user directly pulls the sealing plate by pulling the strip-shaped buckle groove, the sealing plate is applied with a thrust and fed back to the connecting rod, and then the thrust is fed back to the piston through the connecting rod. The limiting rod on the piston is blocked by the baffle and cannot move, and then it is fed back to the piston and finally fed back to the sealing plate. At this time, the sealing plate cannot move, and the strip-shaped groove is still sealed and blocked; thus, it is avoided that the user uses the kit without placing it horizontally, resulting in uneven liquid penetration on the test paper or poor effect, leading to inaccurate test results.

[0015] 2. Even when the user tears the packaging bag and no longer uses the kit, the test paper can still be sealed and preserved, so that it will not deteriorate and be discarded and wasted.

[0016] 3. The rubber suction cup and the rectangular rod are abutted against the desktop. It should be noted that the user needs to press down the kit. At this time, the rubber suction cup can be abutted against the desktop over a large area. The rectangular rod moves due to the downward pressure of the kit, and the upward movement of the rectangular rod drives the rack plate and the block to move upward. After the block moves upward, the air hole on the block is opposite to the pipeline. At this time, the limiting hole on the block is directly opposite to the limiting rod and will not block the limiting rod, and the sealing plate can be opened for subsequent use.

[0017] 4. By pulling the strip-shaped buckle groove to drive the sealing plate to move, the sealing plate is applied with a thrust and fed back to the connecting rod, and then the thrust is fed back to the piston through the connecting rod. Since the pipeline is no longer sealed and blocked by the block, when the piston is applied with a thrust and moves, it will suck the air in the pipeline into the circular groove, so as to suck the air in the inner cavity into the circular groove. The negative pressure state in the inner cavity makes the rubber suction cup adsorb on the desktop. In this way, the stability of the kit can be ensured, and it can be avoided that it is touched and dropped, resulting in inability to detect or inaccurate test results.

[0018] 5. When the user only presses the rectangular rod to move upward, since the distance of the upward movement of the rectangular rod is fixed to make the limiting hole align with the limiting rod, the rubber suction cup will adsorb on the tabletop and be in a fixed position with the rectangular rod. When the user presses the rectangular rod to be in the above-mentioned fixed position, the limiting hole can be aligned with the limiting rod. Otherwise, the limiting rod is still blocked by the baffle, so the sealing plate still cannot be opened. Therefore, there will be no problem that the user uses the kit without placing it horizontally, resulting in uneven liquid penetration on the test paper or poor effect, leading to inaccurate test results.

[0019] In summary, the present invention ensures that the kit needs to be placed horizontally to be used, avoiding inaccurate test results caused by uneven liquid penetration; even if the packaging bag is torn, the test paper can be sealed and preserved, reducing waste. Through the design of the rubber suction cup and the rectangular rod, it is ensured that the kit is stably adsorbed on the tabletop to prevent falling and affecting the test. At the same time, only when the rectangular rod is pressed to a fixed position can the sealing plate be opened, further ensuring horizontal placement during use and improving the test accuracy. The overall design is highly practical and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-9 A rapid detection kit for food allergens includes a kit 1, wherein the kit 1 is provided with a plurality of test paper slots 2, wherein test paper is placed in the test paper slots 2, wherein a plastic transparent plate is fixed in the test paper slots 2, and the test paper slots 2 can be sealed to prevent air from affecting the test paper, causing the test paper to deteriorate or inaccurate results; the kit 1 is provided with a strip groove 3 located above the test paper slot 2, and a drip hole 9 is penetrated through the inner bottom of the strip groove 3, the drip hole 9 is arranged opposite to the test paper and is connected to the test paper slot 2, and the collected liquid (such as serum) is dripped into the drip hole 9, and the liquid penetrates into the test paper through the drip hole 9.

[0024] Among them, the multiple test paper slots 2 are separate strip-shaped placement slots that can hold test papers, that is, the test papers will not affect each other, so as to avoid the test kit 1 being damaged or unqualified, causing some test papers to deteriorate, and thus causing the test results to be false positive or false negative. A sliding groove 11 and a sealing groove 10 are arranged opposite to each other in the strip groove 3. A sealing plate 4 is slidably connected in the sliding groove 11. The sealing plate 4 extends into the sealing groove 10 to seal and block the strip groove 3. The notch of the sealing groove 10, the inner wall of the strip groove 3 and the notch of the sliding groove 11 are all fixed with rubber rings. The sealing plate 4 abuts against the rubber ring to ensure that the strip groove 3 is sealed. Since a plurality of first springs 12 are arranged between the sealing plate 4 and the sliding groove 11, the sealing plate 4 can be limited so that it is not easy to separate from the sealing groove 10.

[0025] In order to facilitate the driving of the sealing plate 4 to move without interfering with the sealing plate 4, a plurality of strip buckle grooves may be provided on the sealing plate 4, and the sealing plate 4 may be driven to move by buckling the strip buckle grooves.

[0026] A circular groove 16 is provided on the inner wall of the slide groove 11, and an exhaust hole 6 connected to the circular groove 16 is penetrated at the upper end of the reagent box 1, and the exhaust hole 6 is located between the baffle 21 and the piston 15; a piston 15 connected to the sealing plate 4 is slidably connected in the circular groove 16, a connecting rod 14 is fixedly connected to the piston 15, a guide ring 13 is fixedly connected in the circular groove 16, the connecting rod 14 penetrates the guide ring 13 and is slidably connected to it, the connecting rod 14 is fixedly connected to the sealing plate 4, and a second spring 17 is fixed on the piston 15 and the circular groove 16.

[0027] A limiting rod 18 is fixedly connected to the piston 15, and the limiting rod 18 passes through the reagent box 1 and is slidably arranged therewith. A removable circular block 5 is provided on the reagent box 1, and the circular block 5 is arranged opposite to the limiting rod 18. A circular hole is penetrated through the reagent box 1, and the circular block 5 is in the circular hole. The circular block 5 is installed in the circular hole by glue or other connection methods, so that it is not easy to get out of the circular hole, but applying a certain pressure can drive the circular block 5 to get out of the circular hole. A mushroom-shaped limiting block made of rubber material is fixed to the end of the limiting rod 18. After the limiting block passes through the circular block 5, the limiting block abuts against the outer wall of the reagent box 1, which can limit the limiting rod 18 and make it difficult to move.

[0028] An inner cavity 23 and a vertical cavity 19 are provided in the reagent box 1. The inner cavity 23 is connected to the circular groove 16 through a pipe 22 located in the reagent box 1. A plurality of rubber suction cups 7 connected to the inner cavity 23 are installed at the bottom of the reagent box 1. Ventilation grooves are penetrated through the rubber suction cups 7, and the ventilation grooves are connected to the inner cavity 23.

[0029] A driving member penetrating the bottom of the reagent box 1 is provided in the inner cavity 23, and the driving member includes a rectangular rod 8 penetrating the bottom of the reagent box 1 and slidingly arranged therewith. In order to ensure the seal between the rectangular rod 8 and the reagent box 1, a rubber film can be covered on the outside of the rectangular rod 8, and the rubber film is fixed on the reagent box 1, so that the sliding part between the rectangular rod 8 and the reagent box 1 can be covered and sealed.

[0030] The upper end of the rectangular rod 8 is fixedly connected to a rack plate 32, to which a stopper 29 is fixedly connected. The rack plate 32 also includes a reset mechanism, which includes a cross block 28 fixed on the stopper 29, and a third spring 24 is fixedly connected to the bottom of the cross block 28. The other end of the third spring 24 is fixedly connected to the inner wall of the inner cavity 23.

[0031] The block 29 can seal the pipeline 22. The block 29 is penetrated by an air hole 30 opposite to the pipeline 22. A transmission rod 31 is provided in the inner cavity 23. The transmission rod 31 penetrates the reagent box 1 and is rotatably connected thereto. The other end of the transmission rod 31 extends into the vertical cavity 19. A gear 33 is fixed on the transmission rod 31, and the gear 33 meshes with the rack plate 32.

[0032] A baffle plate 21 is slidably connected inside a vertical cavity 19, and further includes a driving mechanism capable of driving the baffle plate 21 to move up and down. The driving mechanism includes a circular plate 26 fixed on a transmission rod 31. A connecting rod 27 is eccentrically hinged to the circular plate 26, and the other end of the connecting rod 27 is hinged to the baffle plate 21. A guide plate 20 is fixedly connected inside the vertical cavity 19. The baffle plate 21 passes through the guide plate 20 and is slidably connected thereto. A limiting hole 25 is provided through the baffle plate 21, and a limiting rod 18 can extend into the limiting hole 25 to limit the baffle plate 21.

[0033] When the reagent kit 1 is placed on a tabletop and the driving member is displaced, the rubber suction cup 7 can adsorb on the tabletop before the sealing plate 4 can be opened. When the driving member is displaced and the rubber suction cup 7 cannot adsorb on the contact surface, the sealing plate 4 cannot be opened.

[0034] When the present invention is used, the user tears the packaging bag of the reagent kit 1 and takes out the reagent kit 1; Incorrect usage method 1: If the user directly triggers the sealing plate 4 by pressing the strip-shaped buckle groove, the sealing plate 4 is subjected to a thrust force and feedback to the connecting rod 14. Then, the thrust force is feedback to the piston 15 through the connecting rod 14. The limiting rod 18 on the piston 15 is blocked by the baffle plate 21 and cannot move, and then feedback to the piston 15, and finally feedback to the sealing plate 4. At this time, the sealing plate 4 cannot move, and the strip-shaped groove 3 is still sealed and blocked; thus, it is avoided that the user uses the reagent kit 1 without placing it horizontally, resulting in uneven liquid penetration on the test paper or poor effect, and inaccurate test results. Even when the user tears the packaging bag and no longer uses the reagent kit 1, the test paper can still be sealed and stored so that it will not deteriorate and be discarded and wasted.

[0035] The correct usage method is to place the reagent kit 1 on the tabletop. At this time, the rubber suction cup 7 and the rectangular rod 8 are in contact with the tabletop. It should be noted that the user needs to press down on the reagent kit 1. At this time, the rubber suction cup 7 can be in large-area contact with the tabletop. The rectangular rod 8 moves due to the downward pressure of the reagent kit 1. The upward movement of the rectangular rod 8 drives the rack plate 32 and the block 29 to move upward. After the block 29 moves upward, the air hole 30 on the block 29 is opposite to the pipeline 22. In this way, the pipeline 22 is no longer blocked. The upward movement of the block 29 drives the cross block 28 to move upward. At this time, the third spring 24 is stretched; The upward movement of the rack plate 32 drives the gear 33 to rotate. The rotation of the gear 33 drives the transmission rod 31 to rotate, and then drives the circular plate 26 to rotate. The rotation of the circular plate 26 drives the connecting rod 27 to move. The connecting rod 27 drives the baffle plate 21 to move upward. When the rectangular rod 8 stops moving, at this time, the baffle plate 21 stops moving, and the limiting hole 25 on the baffle plate 21 is aligned with the limiting rod 18; The sealing plate 4 is driven to move by pressing the strip buckle groove, and the sealing plate 4 is applied with thrust and fed back to the connecting rod 14, and then the thrust is fed back to the piston 15 through the connecting rod 14. Since the pipe 22 is no longer sealed and blocked by the block 29, the piston 15 is applied with thrust and moves to suck the air in the pipe 22 into the circular groove 16, thereby sucking the air in the inner cavity 23 into the circular groove 16. The inner cavity 23 is in a negative pressure state, so that the rubber suction cup 7 is adsorbed on the desktop, so as to ensure the stability of the reagent kit and prevent it from being touched and falling, resulting in failure to detect or inaccurate test results. At this time, the reagent kit 1 is in a horizontal state, and the sealing plate 4 is opened; It should be noted that the distance of the rectangular rod 8 moving upward is fixed so that the limiting hole 25 and the limiting rod 18 are aligned, so the rubber suction cup 7 is adsorbed on the desktop and is in a fixed position with the rectangular rod 8; The movement of the piston 15 drives the limiting rod 18 to move, and the limiting rod 18 passes through the limiting hole 25 and finally abuts against the circular block 5. Under the thrust of the limiting rod 18, the limiting rod 18 pushes the circular block 5 to make it separate from the circular hole, and the circular block 5 is separated from the reagent box 1, and finally the limiting rod 18 is fixed in the circular hole; in this way, it can be known whether the reagent box 1 is used by observing the circular block 5; Although the third spring 24 is stretched, the rubber suction cup 7 is adsorbed on the table, and the effect of the third spring 24 is minimal and will not affect the reagent kit 1; The sealing plate 4 is opened and the strip groove 3 is no longer blocked. At this time, the drip holes 9 are exposed, and the user can drip liquid into the multiple drip holes 9; the liquid penetrates the test paper, and the allergen can be found by observing the color of the test paper and comparing the color with the comparison card.

[0036] According to the above description of the correct method of use, there is an incorrect method of use 2: when the user only presses the rectangular rod 8 to move upward, the distance of the rectangular rod 8 moving upward is fixed so that the limit hole 25 can be opposite to the limit rod 18, so the rubber suction cup 7 is adsorbed on the desktop and will be in a fixed position with the rectangular rod 8; when the user presses the rectangular rod 8 to be in the above-mentioned fixed position (the probability of pressing it to make it opposite is small), the limit hole 25 can be opposite to the limit rod 18, otherwise the limit rod 18 is still blocked by the baffle 21, so the sealing plate 4 cannot be opened, so that the user will not use the reagent kit 1 without placing it horizontally, resulting in uneven liquid penetration on the test paper or poor effect, resulting in inaccurate test results.

[0037] After use, the limiting rod 18 is pressed, and under the action of the first spring 12 and the second spring 17, the sealing plate 4 and the like are reset. At this time, the rubber suction cup 7 is no longer adsorbed on the desktop, so that the reagent kit 1 can be removed and processed.

[0038] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention any equivalent replacement or change made according to the technical solution and inventive concept of the present invention.
