[0001] This utility model relates to the field of detection technology, and in particular to a convenient reading card for rapid test strips. Background Technology

[0002] The reader card is used to carry the test sample and work with the test strip to realize the detection function. Through a specific structural design, the test results are presented in a visual form. It is portable and can support rapid testing operations in non-laboratory environments, providing convenient technical support for rapid diagnosis.

[0003] The convenient reading card for rapid test strips is the core carrier used with rapid test strips. It is mainly used to carry test samples and assist in reading results. Its structural design allows the test reaction to be completed within the card, and the results can be presented in a visual way such as color development and fluorescence. It can meet the needs of rapid on-site testing without relying on laboratory equipment and simplifies the testing operation steps.

[0004] In existing technologies, some test strip reading cards use manual sample addition or rely on natural siphon transfer of liquid, which leads to significant deviations in sample addition. Adding too much sample causes excessive dilution of the reaction system, resulting in false negative results, while adding too little sample leads to false positives or difficulty in interpretation due to insufficient sample, affecting the repeatability and reliability of test results. Therefore, a convenient reading card for rapid test strips is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a convenient reading card for rapid test strips, which aims to improve the problem of uneven sample dosage in traditional rapid test cards that leads to deviations in test results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick test strip easy-read card, including a shell, a groove is provided at the bottom of the shell, a slider is slidably connected inside the groove, a slider button is fixedly connected to the front side of the slider, a transmission gear plate is fixedly connected to the rear side of the slider, a base is detachably connected to the bottom of the shell, a rotating support rod is fixedly connected inside the base, a gear turntable is rotatably connected to the top of the rotating support rod, and an optical component is provided at the top of the shell for easy observation of the display slot;

[0007] As a further description of the above technical solution: the optical component includes an observation slot, the observation slot 13 is opened on the outside of the housing 1, a fixing plate is fixedly connected inside the observation slot, and a light-shielding convex lens is fixedly connected inside the fixing plate.

[0008] As a further description of the above technical solution: the top inner wall of the outer shell is provided with a fixing hole, and the fixing hole has a screw-in latch that rotates inside;

[0009] As a further description of the above technical solution: a sample groove is provided on the top inner wall of the outer shell, and a filter pad is fixedly connected inside the sample groove;

[0010] As a further description of the above technical solution: a capillary tube is fixedly connected to the bottom of the filter pad, and the outside of the capillary tube is in contact with the inside of the gear turntable;

[0011] As a further description of the above technical solution: the base is internally fixedly connected to multiple support platforms, and test strips are detachably connected to adjacent sides of the multiple support platforms;

[0012] As a further description of the above technical solution: the top of the transmission gear plate is provided with multiple slots, and the bottom of the screw-in tenon is slidably connected to the inside of one of the slots;

[0013] As a further description of the above technical solution: the rear side of the transmission gear plate is meshed with the outside of the gear turntable, and the inside of the gear turntable is provided with a turntable through hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the screw-in tenon to disengage from the slot, the limiting position on the transmission gear plate is released. Pushing the sliding button causes the slider to slide in the groove, driving the transmission gear plate to move, thereby driving the gear turntable to rotate around the rotating support rod. The gear turntable has a turntable through hole inside. Because the gear turntable has a turntable through hole inside and its top is in contact with the capillary tube, the sample flows into the capillary tube after being filtered by the filter pad through the sample groove. As the turntable rotates, the cross-section of the turntable through hole and the capillary tube changes continuously, accurately controlling the sample flow rate and avoiding interference to the test results caused by too much or too little sample.

[0016] 2. In this invention, a fixed plate is fixed inside the observation slot, and a light-shielding convex lens is positioned above the color development area of ​​the test strip. The light-shielding convex lens can focus and magnify the color development area of ​​the test strip. At the same time, the outer shell structure and the light-shielding convex lens together block stray light from the outside, allowing only vertical light to pass through. The optical element light-shielding convex lens can reduce ambient light interference, making the color change of the color strip clearer. This solves the problem that weak positive results are difficult to identify due to light influence in traditional rapid test cards, effectively improving the accuracy of users' interpretation of test results.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a convenient reading card for rapid test strips, including a shell 1. The shell 1 serves as the overall frame of the reading card, protecting the internal components and providing installation space. A groove 2 is provided at the bottom of the shell 1, providing a base for subsequent devices. A slider 3 is slidably connected inside the groove 2, and the slider 3 slides within the groove 2, transmitting operating power and driving the internal components to move. A button 4 is fixedly connected to the front of the slider 3, and the button 4 is an operating component exposed on the outside of the shell 1. The user drives the slider 3 to move by pushing and pulling the button 4. A transmission gear plate 5 is fixedly connected to the rear of the slider 3, transmitting power to the slider 3. A base 6 is detachably connected to the bottom of the shell 1, providing a base for subsequent devices. A rotating support rod 7 is fixedly connected inside the base 6, providing support for subsequent devices. A gear turntable 8 is rotatably connected to the top of the rotating support rod 7, and the gear turntable 8 is driven to rotate by the transmission gear plate 5. An optical component is provided at the top of the shell 1 for easy observation of the display slot 13, providing the user with a clearer display function.

[0025] Reference Figure 1 and Figure 2The optical components include an observation slot 13, which is used to observe the color development results. The exterior of the observation slot 13 is opened inside the housing 1. The housing 1 and the observation slot 13 work together to reduce stray light. A fixing plate 14 is fixedly connected inside the observation slot 13 to ensure structural stability. A light-shielding convex lens 15 is fixedly connected inside the fixing plate 14 to focus and magnify the color development area.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The housing 1 has a fixing hole 11 inside, which provides a mounting and fixing function for subsequent devices. The fixing hole 11 is connected to a screw-in latch 12 inside, which screws into the fixing hole 11 to fix the subsequent devices. The housing 1 has a sample slot 16 inside, which is used to store the liquid sample to be tested. The sample slot 16 is fixedly connected to a filter pad 17 inside, which filters impurities in the sample to ensure the accuracy of the test. The bottom of the filter pad 17 is fixedly connected to a capillary tube 18, which transfers the sample to the test area through capillary action. The outside of the capillary tube 18 is in contact with the top of the gear turntable 8, and the contact between the capillary tube 18 and the gear turntable 8 prevents liquid leakage. The base 6 has multiple support platforms 19 fixedly connected inside, which are used for support and positioning. The test strips 20 are detachably connected to the adjacent sides of the multiple support platforms 19. The test strips 20 react with the sample and develop color, which is used to judge the test results.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The top of the transmission gear plate 5 is provided with multiple slots 10, which serve a fixing function. The bottom of the screw-in tenon 12 is slidably connected to the inside of one of the slots 10, and the screw-in tenon 12 is connected to the inside of one of the slots 10 for a fixing function. The rear side of the transmission gear plate 5 is meshed with the outside of the gear turntable 8. The gear turntable 8 is rotated by the force of the transmission gear plate 5. The inside of the gear turntable 8 is provided with a turntable through hole 9. The flow rate of the liquid can be controlled by the rotation of the gear turntable 8.

[0028] Working principle: When a sample is added, the rotating screw-in latch 12 disengages from the slot 10 of the transmission gear plate 5, releasing the limiting position of the transmission gear plate 5. The push of the sliding button 4 drives the slider 3 to slide, and the transmission gear plate 5 drives the gear turntable 8 to rotate around the rotating support rod 7. The gear turntable 8 has a turntable through hole 9 inside, and the top of the gear turntable 8 contacts the capillary tube 18. The sample is added into the sample slot 16, filtered by the filter pad 17, and then flows into the capillary tube 18. When the turntable rotates, the cross-section of the turntable through hole 9 and the capillary tube 18 changes continuously, thereby realizing the control of the flow rate.

[0029] When observing the test results, the light-shielding convex lens 15 is positioned above the color development area of ​​the test paper 20 by the fixing plate 14 fixed in the observation slot 13, focusing and magnifying the color development area of ​​the test paper 20. At the same time, the outer shell 1 and the light-shielding convex lens 15 jointly block stray light from the outside, allowing vertical light to pass through. The optical element light-shielding convex lens 15 can reduce ambient light interference, making the color change of the color development strip clearer, reducing ambient light reflection and scattering interference, and solving the problem that weak positive results are difficult to identify due to light influence in traditional rapid test cards, effectively improving the accuracy of users' interpretation of test results.
