Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical consumables technology, and in particular to a test kit with a quick-replaceable test strip. Background Technology
[0002] A test kit (or diagnostic kit) is a single-use medical or laboratory device for a specific testing purpose. It typically contains all the necessary reagents, sample collection materials, and operating instructions, thus requiring a test kit with a quick-change reagent strip.
[0003] According to a test kit disclosed on the patent website (authorization announcement number: CN 217536003 U), "This application discloses a test kit, belonging to the field of medical consumables. A test kit includes: a box with an opening at one end; a sample pool, a reaction pool, and an exhaust column, all disposed within the box and connected sequentially, wherein the sample pool has a sample inlet, and the exhaust column is through-connected to the outside; and a cover disposed on the opening. The test kit of this application not only avoids the risk of damage to the reaction environment within the reaction pool from the external environment, but also prevents the reaction liquid within the reaction pool from leaking into the air, achieving a completely sealed and pollution-free environment."
[0004] Regarding the above description, the applicant believes the following issues exist: Optimization (logical, expanded and supplemented to avoid over-embellishment): Not only can the seal of the lid block the connection between the inside of the box and the external environment, but the preservation solution and the sample to be tested entering the exhaust column can also isolate the environment inside the reaction chamber from the external environment, thus forming a double-layer isolation; thereby avoiding the risk of the external environment damaging the environment inside the reaction chamber, and also avoiding the risk of the reaction solution inside the reaction chamber leaking into the air and generating nucleic acid aerosols that pollute the environment. However, the kit is designed with test tubes of a specific size. If this cannot be adjusted, it may lead to too much or too little sample being added, affecting the accuracy of the test results. Utility Model Content
[0005] To overcome the problem that the kit is designed with test tubes of a specific size, which cannot be adjusted, resulting in too much or too little sample being added, thus affecting the accuracy of the test results.
[0006] The technical solution of this utility model is as follows: a test kit with a quick-change reagent strip, including a base plate; and a test box and a quick-change component. The test box is fixedly connected to the top of the base plate, and the quick-change component is provided on the outside of the test box. A spring plate is fixedly connected to the inside of the test box, a movable plate is slidably connected inside the test box, an installation box is fixedly connected to the outside of the movable plate, a fixed plate is fixedly connected inside the installation box, a sliding rod is slidably connected inside the fixed plate, a pressing block is fixedly connected to the top of the sliding rod, a sliding plate is fixedly connected to the bottom of the sliding rod, a spring one is provided at the middle position between the bottom of the pressing block and the top of the fixed plate, a spring two is fixedly connected to the end of the installation box away from the pressing block, a slider is fixedly connected to the outside of the spring two, a cover plate is rotatably connected to the outside of the test box, a limit block is fixedly connected to the outside of the slider, a spring three is fixedly connected to the outside of the movable plate, and a push plate is fixedly connected to the outside of the spring three.
[0007] Preferably, the mounting box has a through hole, and the limiting block is slidably connected to the inside of the mounting box through the through hole.
[0008] Preferably, the detection box has a second through hole, and the limiting block slides through the first through hole and is connected to the inside of the detection box.
[0009] Preferably, the slider has a groove, and the sliding plate is slidably connected to the inside of the slider through the groove.
[0010] Preferably, when the limiting block disengages from the second through hole of the detection box, the mounting box is released from its restriction, and the moving plate can slide freely inside the detection box.
[0011] Preferably, the mounting box has a through hole three, and the push block is slidably connected to the inside of the mounting box through the through hole three.
[0012] Preferably, the quick-fixing component includes a reagent strip plate, which is fixedly connected to the outside of the test box. A second magnet is fixedly connected to the outside of the reagent strip plate, a first magnet is disposed outside the second magnet, and a transparent plate is fixedly connected to the outside of the first magnet.
[0013] The beneficial effects of this utility model are as follows: When the actuating block is pressed, it drives the sliding plate connected to the bottom to slide within the fixed plate via the sliding rod. The sliding plate moves along the guide groove of the slider, driving the slider to retract into the mounting box, and simultaneously driving the limiting block to exit the through hole of the detection box. At this time, the locking state of the moving plate is released, and it can slide freely along the inner wall of the detection box. By adjusting the distance between the push plate and the spring plate, it can accommodate test tubes of different specifications, ensuring clamping stability during testing and ultimately improving the accuracy of the test results.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-7This utility model provides an embodiment of a test kit with a quick-change reagent strip, including a base plate 1; it also includes a test box 21 and a quick-change assembly. The test box 21 is fixedly connected to the top of the base plate 1. The quick-change assembly is provided on the outside of the test box 21. A spring plate 22 is fixedly connected to the inside of the test box 21. A moving plate 23 is slidably connected inside the test box 21. A mounting box 24 is fixedly connected to the outside of the moving plate 23. A fixing plate 25 is fixedly connected inside the mounting box 24. A sliding rod 26 is slidably connected inside the fixing plate 25. A pressing block 27 is fixedly connected to the top of the sliding rod 26. A sliding plate 29 is fixedly connected to the bottom of the sliding rod 26. A spring 28 is provided at the midpoint between the bottom of the pressing block 27 and the top of the fixing plate 25. A spring 210 is fixedly connected to the end of the mounting box 24 away from the pressing block 27. A slider 211 is fixedly connected to the outside of the spring 210. A cover plate 215 is rotatably connected to the outside of the test box 21. An externally fixed limit block 212 is connected, and a spring 213 is externally fixed to the movable plate 23. A push plate 214 is externally fixed to the spring 213. When the distance between the spring plate 22 and the push plate 214 is not suitable for the size of the test tube, pressing the push block 27 causes the push block 27 to drive the sliding plate 29 at the bottom of the sliding rod 26 to slide inside the fixed plate 25. At this time, the sliding plate 29 will slide in the groove of the slider 211, causing the slider 211 to move towards the fixed plate 25 under the action of the sliding plate 29. The internal sliding of the mounting box 24 causes the slider 211 to retract the limiting block 212 from the through hole of the detection box 21. At this time, the moving plate 23 is released from its restriction and slides inside the detection box 21, thereby adjusting the distance between the push plate 214 and the spring plate 22 to accommodate the size of the test tube. The mounting box 24 has a through hole, and the limiting block 212 is slidably connected to the inside of the mounting box 24 through the through hole. The mounting box 24 provides a foundation for the installation of other components.
[0024] Please see Figure 2-6In this embodiment, the detection box 21 has a second through hole, and the limiting block 212 slides through the first through hole and is slidably connected to the inside of the detection box 21. Due to the setting of the limiting block 212, it is pushed into the inside of the detection box 21 by the second spring 210 outside the slider 211 to fix the moving position of the moving plate 23. The slider 211 has a first sliding groove, and the sliding plate 29 slides through the first sliding groove and is slidably connected to the inside of the slider 211. Due to the setting of the sliding plate 29, it is beneficial to drive the slider 211 to slide inside the mounting box 24. When the limiting block 212 disengages from the second through hole of the detection box 21, the mounting box 24 is released from restriction, and the moving plate 23 can slide freely inside the detection box 21. Due to the setting of the detection box 21, it is beneficial to provide placement space for storing test tubes. The mounting box 24 has a third through hole, and the pressing block 27 slides through the third through hole and is slidably connected to the inside of the mounting box 24. Due to the setting of the pressing block 27, it is beneficial to push the sliding plate 29 at the bottom of the sliding rod 26 to slide inside the mounting box 24.
[0025] Please see Figure 7 In this embodiment, the quick fixation component includes a reagent strip 31, which is fixedly connected to the outside of the test box 21. A second magnet 34 is fixedly connected to the outside of the reagent strip 31, and a first magnet 33 is provided on the outside of the second magnet 34. A transparent plate 32 is fixedly connected to the outside of the first magnet 33. The first magnet 33 is provided to facilitate the use of the second magnet 34 to fix the transparent plate 32 to the outside of the reagent strip 31.
[0026] When the distance between the spring plate 22 and the push plate 214 is not suitable for the size of the test tube, the push block 27 is pressed, causing the push block 27 to drive the sliding plate 29 at the bottom of the sliding rod 26 to slide inside the fixed plate 25. At this time, the sliding plate 29 will slide in the groove of the slider 211, causing the slider 211 to slide into the mounting box 24 under the drive of the sliding plate 29. At this time, the slider 211 will drive the limiting block 212 to retract from the through hole of the detection box 21. At this time, the moving plate 23 is released from the restriction and moves inside the detection box 21, thereby adjusting the distance between the push plate 214 and the spring plate 22 to adapt to the size of the test tube. By pulling up the transparent plate 32, the magnet 1 33 and the magnet 2 34 are separated. Then the reagent strip is placed on the back of the magnet 1 33. Then the transparent plate 32 is attached to the outside of the reagent strip plate 31, so that the magnet 1 33 and the magnet 2 34 are attracted to each other.
[0027] By pressing the actuating block 27, the sliding plate 29 connected to the bottom moves within the fixed plate 25 via the sliding rod 26. The sliding plate 29 moves along the guide groove of the slider 211, driving the slider 211 to retract into the mounting box 24, simultaneously causing the limiting block 212 to exit the through hole of the detection box 21. At this time, the locking state of the moving plate 23 is released, allowing it to slide freely along the inner wall of the detection box 21. By adjusting the distance between the pushing plate 214 and the spring plate 22, different specifications of test tubes can be accommodated, ensuring clamping stability during testing and ultimately improving the accuracy of the test results.
