[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Refer to the instruction manual appendix Figures 1-6 This utility model provides a 25-hydroxyvitamin D time-resolved detection card, including a test card 2 disposed inside the card body 1 for detecting the time of 25-hydroxyvitamin D. The card body 1 is provided with an addition hole 3 for adding samples and an observation window 4 for observing the detection results. The observation window 4 is disposed on one side of the addition hole 3. The card body 1 is provided with a sealing component to prevent dust contamination.

[0027] The encapsulation component includes an encapsulation plate 5 disposed on the top of the card body 1. The encapsulation plate 5 is vertically aligned with the position of the addition hole 3. A deformable encapsulation plug 6 is installed at the bottom of the encapsulation plate 5. The bottom end of the encapsulation plug 6 extends into the interior of the addition hole 3. Two spaced positioning grooves 15 are formed at the bottom of the encapsulation plug 6. Two positioning posts 16 for fixing the encapsulation plug 6 are installed at the top of the end of the card body 1 away from the observation window 4. Because anti-slip pads 17 for enhancing grip stability are installed on both the front and rear sides of the encapsulation plate 5, the friction between the inspector's hand and the card body 1 can be enhanced, thereby improving the stability of the inspector holding the card body 1 and preventing it from loosening and falling off.

[0028] In use, the staff lifts the encapsulation plate 5 to pull out the encapsulation plug 6, and uses the positioning groove 15 on the encapsulation plug 6 to engage with the outside of the positioning post 16. The positioning post 16 limits the encapsulation plug 6 to prevent it from falling out and being lost. Then, the tester places the sample on the test card 2 through the addition hole 3 and uses the test card 2 to test for 25-hydroxyvitamin D. At the same time, the tester places the encapsulation plug 6 on the encapsulation plate 5 into the addition hole 3 to seal the addition hole 3. This prevents dust and other impurities from adhering to the outside of the test card 2 and causing contamination, thus ensuring the accuracy of the test card 2.

[0029] At the same time, to avoid the reuse of inspection card 2 due to negligence, inspection card 2 needs to be labeled with reminders, such as... Figure 1 , 2 As shown in Figures 4 and 5, the encapsulation plate 5 has a cavity 7 inside, and a fixed shaft 9 for a limiting adjustment ring 8 is installed inside the cavity 7. The adjustment ring 8 is sleeved on the outside of the fixed shaft 9. The top of the adjustment ring 8 is machined with a used marking surface 10 and an unused marking surface 11. The unused marking surface 11 is located on the side of the addition hole 3 near the observation window 4. The top of the front end of the encapsulation plate 5 has an adjustment hole 12, which is located on the top of the cavity 7 and communicates with the cavity 7.

[0030] When the test card 2 is not in use, the unused marking surface 11 on the adjusting ring 8 is inside the adjusting hole 12, informing the testing personnel that the test card 2 has not been used. After the test card 2 is used, the testing personnel move the adjusting ring 8 so that the used marking surface 10 on the adjusting ring 8 rotates to the adjusting hole 12, informing the testing personnel that the test card 2 has been used. This can avoid the situation of repeated use due to negligence and reduce medical risks.

[0031] During the operation of the adjusting ring 8, in order to prevent the adjusting ring 8 from becoming loose, it is necessary to limit the adjusting ring 8, such as... Figure 4 As shown, multiple anti-slip strips 13 are installed on the top of the adjusting ring 8 on both the used marking surface 10 and the unused marking surface 11. A deformable limiting pad 14 is installed on the top of the inner cavity of the cavity 7 to enhance the stability of the adjusting ring 8. The front end of the limiting pad 14 is sleeved on the outside of the fixed shaft 9. By using the deformable limiting pad 14, when the adjusting ring 8 rotates into the cavity 7 and contacts the limiting pad 14, the limiting pad 14 is squeezed and deformed by the adjusting ring 8. This allows the limiting pad 14 to rebound and squeeze and limit the adjusting ring 8, ensuring the stability of the adjusting ring 8 after adjustment. At the same time, the anti-slip strips 13 on the adjusting ring 8 can enhance the friction between the inspector's hand and the adjusting ring 8, thereby ensuring the stability of the adjusting ring 8 when the inspector rotates it.

[0032] Refer to the instruction manual appendix Figure 6This utility model provides a reagent kit, including a box 18 for storing card body 1 and test card 2. The box 18 stores card body 1 and test card 2, thereby facilitating the transportation and carrying of card body 1 and test card 2.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
