Description

Technical Field

[0001] The present invention relates to the technical field of animal immune disease detection, in particular to a kit for animal immune disease detection. Background Art

[0002] In the field of veterinary medicine, especially for the diagnosis of animal immune diseases, timely diagnosis of immune diseases can detect and isolate sick animals, prevent the spread of diseases in animal groups, and protect other healthy animals. In the diagnosis of animal immune diseases, ELISA kits are mainly used to verify the efficacy of vaccines and whether booster immunization is needed, which is of great significance for protecting animal health and preventing the spread of diseases.

[0003] ELISA kit, the full name of which is enzyme-linked immunosorbent assay kit, is a biochemical method used to quantitatively detect the concentration of target substances in liquid samples. The kit is composed of ELISA plates, standards, sample diluent bottles, detection antibodies, multiple washing buffer bottles, substrates, stop solution bottles, sealing plates, self-sealing tapes and instructions.

[0004] Among them, the use of ELISA plates often requires adjusting the number of wells according to experimental requirements and removing and storing excess wells. However, traditional test kits usually do not provide a convenient way to remove or store excess ELISA well strips, resulting in the need for practical personnel to spend a lot of time and energy to manually press the excess wells one by one to remove them during the operation.

[0005] In addition, the detection of animal immune diseases often needs to be carried out under specific conditions, such as light-proof reaction, etc. Traditional test kits usually do not provide special solutions for these special conditions, and users often need to prepare additional accessories such as light-proof sealing bags, which increases the complexity and cost of the experiment.

[0006] At the same time, when injecting the test liquid into the small holes of the ELISA plate, the liquid may overflow and contaminate the experimental table due to the small holes of the ELISA plate, which requires time-consuming cleaning by the experimenter;

[0007] In addition, the ELISA plate needs to be cleaned after use. Currently, after cleaning, the experimenters often need to manually grab the ELISA plate and tap the table to drain the water. This is not only cumbersome, but also difficult to ensure that the water is completely drained.

[0008] In summary, the existing animal immune disease detection kits still have many inconveniences and limitations during use, and cannot meet the user's needs for convenient, efficient and accurate detection. Therefore, the development of a new, fully functional animal immune disease detection kit has important practical significance and application value. Summary of the invention

[0015] Furthermore, the liquid-absorbing cover is a sponge cover or a cotton cover.

[0016] Furthermore, the height between the support frame and the side plate body is smaller than the overall height of the cleaning interference structure.

[0017] Furthermore, the rubber film is connected to a liquid absorbent pad on one side facing the support frame via a Velcro structure, and the material of the liquid absorbent pad is the same as that of the liquid absorbent jacket.

[0018] Furthermore, the two U-shaped rails are symmetrically connected with a plurality of elastic support structures, which extend into the U-shaped frame plate.

[0035] The number of the small holes on the ELISA plate 4 is equal to the number of the cleaning conflict structures 33 and they correspond one to one.

[0036] Specifically, the outer sealing film of the reagent box body 1 is torn open, and then the flip cover 2 is opened, and the internal ELISA plate 4, the ziplock bag 5 and the multiple detection reagents 6 inserted on the cushion seat 7 are taken out, and then the multifunctional side plate structure 3 is pulled out of the opening of the reagent box body 1 and placed on the laboratory bench to perform animal immune disease diagnosis and detection work; when the ELISA plate 4 is needed during the detection process, the packaging bag of the ELISA plate 4 is torn open, the ELISA plate 4 is taken out, and according to the number of ELISA plates 4 to be used, the excess ELISA well plate strips are removed and put into the ziplock bag 5 for storage. When taking out the excess well plates of the ELISA plate 4, the side plate body 31 is grabbed, and the bottom rubber film 313 is pressed by fingers to contact the multiple cleaning resistance structures 33, and the corresponding number of cleaning resistance structures 33 are contacted and pushed into the telescopic grooves 341 of the support frame 34. The cleaning resistance structures 33 can be extended in appropriate horizontal and vertical quantities according to needs. The user only needs to align the ELISA plate 4 with the extended cleaning resistance structures 33 and press it down to push the excess ELISA well plate strips out of the casing. The ELISA well plate strips at different positions can be taken out at will, which is relatively convenient and does not require manual pressing one by one. After the excess ELISA well plate strips are taken out of the ELISA plate 4, the animal immune disease detection experiment is started. When the ELISA plate 4 needs to be subjected to a light-proof reaction during practical use, all the cleaning resistance structures 33 can be pushed into the telescopic groove 341 of the support frame 34, thereby leaving an internal space between the support frame 34 and the side panel body 31, and the ELISA plate 4 can be inserted into the internal space for a light-proof reaction. There is no need to prepare a light-proof sealing bag, thereby reducing accessories.

[0037] The height between the support frame 34 and the side plate body 31 is smaller than the overall height of the cleaning interference structure 33 , and when the cleaning interference structure 33 separates from the telescopic slot 341 of the support frame 34 and falls onto the side main plate body 31 , it will not be displaced or detached.

[0038] In this embodiment, two concave seats 342 are symmetrically fixed on the opposite side walls inside the telescopic groove 341, and the cleaning interference structure 33 includes a telescopic block 331, and two limit blocks 332 are symmetrically fixed on the opposite sides of the upper part of the telescopic block 331. A stop block 333 is fixed on the top of the telescopic block 331, and a liquid-absorbing jacket 334 is sleeved on the outside of the stop block 333. The telescopic block 331 is inserted into the telescopic groove 341 through the two limit blocks 332 and is clamped and limited with the two concave seats 342, and the height between the bottom of the telescopic block 331 and the side plate body 31 is greater than the thickness of the ELISA plate 4.

[0039] Specifically, when taking out the excess well plates of the ELISA plate 4, the side plate body 31 is grabbed, and the bottom rubber membrane 313 is pressed by fingers to contact with the multiple cleaning resistance structures 33, and the corresponding number of cleaning resistance structures 33 are pushed into the telescopic groove 341 of the support frame 34 and extended; the telescopic block 331 is forced to enter the telescopic groove 341 upward, and is fixed in the concave seat 342 through the connected limit block 332, and the resistance block 333 protrudes outside; the multiple cleaning resistance structures 33 can be extended in appropriate horizontal and vertical quantities according to needs, and the user only needs to align the ELISA plate 4 with the multiple extended cleaning resistance structures 33 and press them down to push the excess ELISA well plate strips out of the casing, and the ELISA well plate strips at different positions can be taken out arbitrarily, which is relatively convenient and does not need to be pressed out one by one manually;

[0040] A conical absorbent coat 334 is installed on the top of the block 333 of each cleaning resistance structure 33. When the ELISA plate 4 is used and cleaned, the support plate is picked up, and the absorbent coats 334 of the multiple blocks 333 are aligned with the small holes of the ELISA plate 4 to contact it. The absorbent coats 334 are made of cotton material, which absorbs the liquid in the small holes of the ELISA plate 4 to keep it clean. There is no need to manually grab the ELISA plate 4 and pat it on the table to drain water. The operation is simple and convenient, and it saves time and effort.

[0041] The force of the enzyme-labeled well strip pushed out is smaller than the resistance of the cleaning resistance structure 33 being engaged in the telescopic groove 341 , so that the cleaning resistance structure 33 will not be pressed down and separated from the telescopic groove 341 .

[0042] The liquid-absorbing cover 334 is a sponge cover or a cotton cover, and the sponge cover or the cotton cover can absorb the liquid well.

[0043] Embodiment 2, on the basis of embodiment 1, the rubber membrane 313 is connected to the liquid absorbent pad 311 through the Velcro structure on the side facing the support frame 34, the material of the liquid absorbent pad 311 is the same as the material of the liquid absorbent jacket 334, and multiple elastic support structures are symmetrically connected inside the two U-shaped rails 321, and the multiple elastic support structures extend into the U-shaped frame plate 32. The two sides of the support frame 34 are inserted into the two U-shaped rails 321 to squeeze and shrink the multiple elastic support structures inside the U-shaped rails 321.

[0044] Specifically, when injecting the detection liquid into the small hole of the ELISA plate 4, the two U-shaped rails 321 can be pulled out of the support plate, and the support plate carrying multiple cleaning resistance structures 33 can be separated from the U-shaped frame plate 32. The two elastic support structures are extended, and the ELISA plate 4 is placed on the multiple elastic support structures and suspended in the air. During the injection of the detection liquid, part of the liquid is injected too much and flows out of the ELISA plate 4 and drips. The liquid can be absorbed by the absorbent pad 311 to prevent contamination of the desktop, and no manual cleaning is required. The absorbent pad 311 is connected by a Velcro structure and can be torn open and replaced with a new absorbent pad 311 later, which is relatively convenient.

[0045] In this embodiment, the elastic support structure includes a connecting shaft 3221 rotatably connected to the inside of the U-shaped rail 321, a support rod 322 is fixedly connected to the upper part of the connecting shaft 3221, a torsion spring 3222 is sleeved on the lower part of the connecting shaft 3221, and the two ends of the torsion spring 3222 are respectively fixedly connected to the inner wall of the U-shaped rail 321 and the support rod 322.

[0046] Specifically, the support rod 322 is rotatably installed inside the U-shaped rail 321 through the connecting shaft 3221, and is elastically limited by the torsion spring 3222. Under the normal state, the torsion spring 3222 drives the support rod 322 to rotate out of the U-shaped rail 321. When the support frame 34 is inserted into the U-shaped rail 321, the support rod 322 is squeezed and retracted into the U-shaped rail 321. The torsion spring 3222 contracts and accumulates force. When the support frame 34 is separated from the U-shaped rail 321, the torsion spring 3222 rebounds and drives the support rod 322 to rotate out. At this time, the ELISA plate 4 can be placed on multiple support rods 322 and suspended in the air.

[0047] Working principle:

[0048] When in use, tear off the outer sealing film of the reagent box body 1, then open the flip cover 2, take out the internal ELISA plate 4, the ziplock bag 5 and the multiple detection reagents 6 inserted on the cushion 7, then pull out the multifunctional side plate structure 3 from the opening of the reagent box body 1, and place it on the laboratory table for use:

[0049] When the ELISA plate 4 is needed during the detection process, the packaging bag of the ELISA plate 4 is torn open, the ELISA plate 4 is taken out, and according to the number of ELISA plates 4 to be used, the excess ELISA well strips are removed and stored in the ziplock bag 5;

[0050] When taking out the extra wells of the ELISA plate 4, grab the side plate body 31, press the bottom rubber membrane 313 with your fingers to contact the multiple cleaning resistance structures 33, and push the corresponding number of cleaning resistance structures 33 into the telescopic grooves 341 of the support frame 34 and extend out;

[0051] The telescopic block 331 is forced upward into the telescopic slot 341, and is fixed in position by the connected limiting block 332 which is inserted into the concave seat 342, and the stop block 333 protrudes outside;

[0052] The plurality of cleaning resistance structures 33 can be extended in appropriate horizontal and vertical quantities as required. The user only needs to align the ELISA plate 4 with the plurality of extended cleaning resistance structures 33 and press them down to push the excess ELISA well strips out of the housing. The ELISA well strips at different positions can be taken out at will, which is relatively convenient and does not require manual pressing one by one.

[0053] After the ELISA plate 4 takes out the extra ELISA well strips, the animal immune disease detection experiment begins. When the ELISA plate 4 needs to be subjected to a light-proof reaction during practical use, the entire cleaning resistance structure 33 can be pushed into the telescopic groove 341 of the support frame 34, thereby leaving an internal space between the support frame 34 and the side plate body 31, and the ELISA plate 4 can be inserted into the internal space for a light-proof reaction, without the need to prepare a light-proof sealing bag, thereby reducing accessories;

[0054] When the detection liquid is injected into the small hole of the ELISA plate 4, the two U-shaped rails 321 can be pulled out of the support plate, and the support plate carrying multiple cleaning resistance structures 33 detaches from the U-shaped frame plate 32, and the two elastic support structures extend. When the support frame 34 detaches from the U-shaped rail 321, the torsion spring 322 rebounds and drives the support rod 322 to rotate out. At this time, the ELISA plate 4 can be placed in the air on multiple support rods 322. During the injection of the detection liquid, some liquid is injected too much and flows out of the ELISA plate 4 and drips. The liquid can be absorbed by the absorbent pad 311 to prevent contamination of the desktop, and no manual cleaning is required. The absorbent pad 311 is connected by a Velcro structure and can be torn open and replaced with a new absorbent pad 311 for use later, which is relatively convenient.

[0055] After the ELISA plate 4 is used and cleaned, the water in each small hole can be cleaned through multiple cleaning resistance structures 33. A conical liquid-absorbing jacket 334 is installed on the top of the resistance block 333 of each cleaning resistance structure 33. The support plate is picked up, and the liquid-absorbing jackets 334 of the multiple resistance blocks 333 are aligned with the small holes of the ELISA plate 4 to contact with them. The liquid-absorbing jackets 334 are made of cotton material, which absorbs the liquid in the small holes of the ELISA plate 4 to keep it clean. There is no need to manually grab the ELISA plate 4 and pat it on the desktop to drain water. The operation is simple and convenient, and it saves time and effort.

[0056] At a later stage, the plurality of cleaning resistance structures 33 can be carried on the support frame 34 to the disinfection room for disinfection and cleaning, and can be reinserted into the U-shaped frame for repeated use.
