[0018] Reference Figure 1-5 This utility model provides a molecular diagnostic test card, which includes a test shell 1, an observation slot 11 on the test shell 1, symmetrical pull holes 17 on the side of the test shell 1, and push-pull rods 9 correspondingly connected in the pull holes 17 to facilitate simultaneous operation on both sides. The other end of the test shell 1 has a placement slot 16 to reserve installation space for the heating component.

[0019] Specifically, a positioning ring 18 is fixedly connected to the side of the observation slot 11, and a transparent plastic sealing cover 2 is fitted on the positioning ring 18 to ensure that the detection process is safe and reliable.

[0020] Specifically, a sample pad 12 is movably connected inside the test housing 1, a binding pad 13 is movably connected inside the test housing 1, a nitrocellulose membrane 14 is movably connected inside the test housing 1, and an absorbent pad 15 is movably connected inside the test housing 1. The nitrocellulose membrane 14 is movably connected to the observation slot 11 to ensure the visualization of the test results.

[0021] Specifically, a sealing plate 3 is fixedly connected to one end of the push-pull rod 9, a bearing plate 7 is fixedly connected to the side of the sealing plate 3, a permeation bearing mesh 8 is fixedly connected through the bearing plate 7, and the bearing plate 7 is movably connected inside the test shell 1 to realize the controllable transmission of the sample and optimize the sample processing flow.

[0022] Specifically, the other end of the push-pull rod 9 is fixedly connected to a bearing shaft 10, and the side of the bearing shaft 10 is fixedly connected to a friction push block 5.

[0023] Specifically, a sliding groove 4 is provided on the side of the pull hole 17, and the friction push block 5 is movably connected to the sliding groove 4 to ensure that the push-pull rod 9 slides smoothly in the pull hole 17, while providing a gripping point during operation.

[0024] Specifically, a return spring 20 is correspondingly connected within the observation slot 11. The return spring 20 is movably connected to the push-pull rod 9, and one end of the push-pull rod 9 is movably connected to the bearing shaft 10 to ensure that each component returns to its initial position.

[0025] Specifically, an external power supply terminal 6 is movably connected to the side of the placement slot 16, and a heating tube 19 is fixedly connected to the side of the external power supply terminal 6. The heating tube 19 is movably connected inside the placement slot 16, so that the test card can adapt to the temperature requirements of different test items.

[0026] Working principle: The sample is added through the inlet formed by the push-pull rod 9 and the sealing plate 3, and carried by the permeation carrier mesh 8. The user pushes the push-pull rod 9, moving the carrier plate 7 and the permeation carrier mesh 8 to controllably transfer the sample to the sample pad 12, preventing random sample diffusion and precisely controlling the sample processing flow. After initial processing on the sample pad 12, the sample flows sequentially to the conjugation pad 13, the nitrocellulose membrane 14, and the absorbent pad 15. On the conjugation pad 13, the target substance in the sample binds to the marker, subsequently undergoing an immunoreaction and color development on the nitrocellulose membrane 14. Since the nitrocellulose membrane 14 extends to the observation tank 11, the user can observe the color development results through the transparent plastic sealing cover 2 on the positioning ring 18 on the side of the observation tank 11. The transparent plastic sealing cover 2 prevents external contamination from interfering with the detection. If the test requires a specific temperature environment, a power supply can be connected through the external power terminal 6 on the side of the placement tank 16, and the heating tube 19 controls the temperature inside the test card. Once the test is complete, the external force on the push-pull rod 9 is removed, and the reset spring 20 in the observation slot 11 releases its elastic potential energy, causing the push-pull rod 9 and related components to reset.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
