Description

Technical Field

[0001] This utility model relates to the field of test card sealing shell technology, specifically a closed immunochromatographic reagent test card compartment. Background Technology

[0002] An immunochromatographic analyzer is an analytical instrument used in basic medical fields. Immunochromatographic test strip technology is widely used in various areas of point-of-care testing (POCT) for rapid detection. The reagents to be tested include colloidal gold, latex, and immunofluorescence reagents. During detection, the system acquires sample information by capturing images or colors after the sample has been tested. A wide range of samples can be tested, including human or animal body fluids such as blood and urine, as well as cell or tissue specimens. Its key feature is that specific antibodies are immobilized on a specific zone of the nitrocellulose membrane on the chromatography card. When this zone comes into contact with the sample (urine or serum), the antibody specifically binds, and the area displays a certain color. The intensity of the color is proportional to the concentration of the sample being tested. An image acquisition device, such as a CCD or CMOS sensor, acquires the color information of the chromatography strip. Image processing and analysis of the color development results yield quantitative detection results.

[0003] In short, the specific operating procedure is as follows: first, place the test solution against the chromatography test card, allow the test card to wait for 15-20 minutes, and then insert the chromatography test card into the immunochromatographic analyzer (e.g., Figure 5 The test can be performed inside the test strip (as shown). However, the chromatography test strip requires a certain amount of time to complete the test. During this process, viruses and other microorganisms from the external environment may enter the test strip, potentially affecting the test results.

[0004] For example, the closed immunochromatographic reagent test card compartment proposed in document number "CN213337657U" involves placing the reagent card inside the compartment and then closing the door. While this process avoids exposing the reagent card to air, the large size of the compartment means that a significant amount of air remains inside, which can still affect the chromatographic test card. Therefore, we propose a closed immunochromatographic reagent test card compartment to address these technical issues. Utility Model Content

[0005] To address the shortcomings of existing chromatographic test cards, which are susceptible to interference with test results when exposed to air, this invention provides a closed immunochromatographic reagent test card compartment. This compartment has the advantage of sealing the chromatographic test card within a sealed compartment, isolating it from the external environment, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a closed immunochromatographic reagent detection card compartment, including a sealed compartment body, one end of the sealed compartment body is provided with a placement opening, the placement opening is provided with a compartment cover, and the inner wall of the sealed compartment body is provided with at least one support ridge perpendicular to the plane where the opening is located.

[0007] The chromatography test card is inserted into the sealed chamber through the placement port. The size of the internal cavity of the sealed chamber and the chamber cover matches the size of the chromatography test card, so that the chromatography test card will not shake in the sealed chamber and the surface of the chromatography test card is in contact with the support edge.

[0008] Preferably, a first slot is provided on the outer edge of the placement opening;

[0009] The inner edge of the opening of the compartment cover is provided with a second slot that matches the first slot. The second slot is tightly engaged with the first slot, so that the sealed compartment body is flush with the inner and outer surfaces of the compartment cover.

[0010] Preferably, the compartment cover has a notch on the side near the first slot.

[0011] Preferably, there are two support ridges symmetrically arranged on the bottom surface of the sealed chamber, and the bottom of the chromatography detection card is placed on the support ridges, so that there is a gap between the bottom surface of the chromatography detection card and the bottom of the sealed chamber.

[0012] Preferably, the support ridge is elastic, and under the support of the elastic force of the support ridge, the display window on the top surface of the chromatography detection card is closely attached to the top surface inside the sealed chamber.

[0013] Preferably, the sealed chamber is transparent, allowing direct observation of the display window and dropper on the chromatography test card through the sealed chamber.

[0014] Preferably, the top of the sealed chamber is provided with a detection port and an observation port, the positions of which correspond to the display window and the droplet port on the chromatography detection card, respectively, and the detection port and the observation port are sealed with a transparent sealing film.

[0015] Preferably, a sealing groove is provided around the drip nozzle, and the sealing groove is sealed by a sealing plate, which is tightly engaged in the sealing groove.

[0016] Compared with the prior art, this invention allows the chromatographic detection card to be firmly fixed inside the sealed chamber without shaking during use. After the chromatographic detection card is inserted into the sealed chamber, the sealed chamber can be directly inserted into the immunochromatographic analyzer. The sealed chamber is shaped to match the chromatographic detection card and is sealed by the chamber cover. Furthermore, the sealed chamber is small in size and fits tightly to the chromatographic detection card, which not only improves the detection accuracy but also avoids interference from the external environment.

[0023] 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.

[0024] Please see Figures 1 to 4 The technical solution provided by this utility model is: a closed immunochromatographic reagent detection card compartment, including a sealed compartment 1, one end of the sealed compartment 1 is provided with a placement port 13, and a compartment cover 7 is provided on the placement port 13;

[0025] The chromatography detection card 11 is inserted into the sealed chamber 1 through the placement port 13. The internal cavity size of the sealed chamber 1 and the chamber cover 7 matches that of the chromatography detection card 11, so that the chromatography detection card 11 will not shake inside the sealed chamber 1. The sealed chamber 1 and the chamber cover 7 are rectangular structures, and their specific shapes are consistent with the shape of the chromatography detection card 11.

[0026] First, let's explain the chromatography test card 11. When using it, as follows... Figure 1 As shown, the test solution is dripped into the chromatographic test card through the dropper 9. After waiting 15-20 minutes, the test result will be displayed in the display window 12. Then, the chromatographic test card 11 can be inserted into the immunochromatographic analyzer (e.g., [insert instrument name here]). Figure 5 The detection card slot (as shown) Figure 5Within the area indicated by the middle arrow A, allow the immunochromatographic analyzer to analyze the test results;

[0027] This application is designed for situations where a 15-20 minute waiting period is required after the test solution is added to the dropper 9. After the chromatography test card 11 is inserted into the card compartment and sealed, the interference of the external environment on the test results can be reduced.

[0028] The specific structural relationship between the sealed chamber 1 and the chromatography detection card 11 will be described below. When the chromatography detection card 11 is placed inside the sealed chamber 1, as follows... Figure 3 As shown, the end of the chromatography detection card 11 near its droplet 9 protrudes to the outside, while the portion protruding from the sealed chamber 1 is located inside the chamber cover 7. The operator can easily insert and remove the chromatography detection card 11 by pinching one end. A first slot 5 is provided on the outer edge of the placement port 13, and a second slot 14 matching the first slot 5 is provided on the inner edge of the opening of the chamber cover 7. In use, the second slot 14 is tightly engaged with the first slot 5, and the inner and outer surfaces of the sealed chamber 1 and the chamber cover 7 are flush. The chamber cover 7 firmly presses the end of the chromatography detection card 11 inside the sealed chamber 1. The chamber cover 7 and the sealed chamber 1 are connected by an insert-and-plug mechanism with an interference fit to prevent the chamber cover 7 from loosening.

[0029] like Figure 1 As shown, due to the tight fit between the chromatography detection card 11 and the sealed chamber 1, air inside the sealed chamber 1 is difficult to expel when the chromatography detection card 11 is inserted into the sealed chamber 1. Therefore, to facilitate insertion, at least one support ridge 4 perpendicular to the plane of its opening is provided on the inner wall of the sealed chamber 1, and the surface of the chromatography detection card 11 contacts the support ridge 4. In actual use, there are two support ridges 4 symmetrically arranged on the bottom surface of the sealed chamber 1. The bottom of the chromatography detection card 11 rests on the support ridge 4, creating a gap between the bottom surface of the chromatography detection card 11 and the bottom of the sealed chamber 1. The air squeezed out by the chromatography detection card 11 will be discharged outward from the gap.

[0030] Furthermore, the supporting rib 4 is elastic and made of elastic rubber. Supported by the elasticity of the supporting rib 4, the display window 12 on the top surface of the chromatography test card 11 is tightly attached to the inner top surface of the sealed chamber 1. Because the immunochromatographic analyzer needs to test the chromatography test card 11 after the sealed chamber 1 is inserted, this design ensures that there is no gap between the display window 12 on the top of the chromatography test card 11 and the sealed chamber 1, resulting in more accurate test results.

[0031] The sealed chamber 1 in this application has two implementation schemes:

[0032] Firstly, in one embodiment of the sealed chamber 1, the sealed chamber 1 is transparent, allowing direct observation of the display window 12 and the dropper 9 on the chromatography detection card 11 through the sealed chamber 1. The sealed chamber 1 and the chamber cover are made of transparent plastic.

[0033] Secondly, in another embodiment of the sealed chamber 1, the sealed chamber 1 and the cover can be transparent or not. The top of the sealed chamber 1 is provided with a detection port 2 and an observation port 3. The positions of the detection port 2 and the observation port 3 correspond to the positions of the display window 12 and the dropper 9 on the chromatography detection card 11, respectively. The detection port 2 and the observation port 3 are sealed by a transparent sealing film, and the detection results can be observed through the sealing film. However, regardless of whether it is the first embodiment or the other embodiment, the top surface of the chromatography detection card 11 can be tightly attached to the inner wall of the sealed chamber 1 with the support of the support rib 4, so that the chromatography detection card 11 is firmly fixed and will not shake.

[0034] It should be noted that after the support ridge 4 is squeezed by the chromatography detection card 11, the support ridge 4 will be flattened and its volume can be ignored. Therefore, the gap between the support ridge 4 and the chromatography detection card 11 will not interfere with the detection results.

[0035] To further enhance the sealing effect and reduce interference from the external environment on the detection structure, this application also improves the chromatography detection card 11. First, the display window 12 on the chromatography detection card 11 is sealed with a transparent sealing film, and a sealing groove 8 is provided around the dropper 9. The sealing groove 8 is sealed by a sealing plate 10, which is tightly engaged in the sealing groove 8. When the detection liquid is dropped in, the sealing plate 10 is engaged in the sealing groove 8 and sealed, thus ensuring that the test strip inside the chromatography detection card 11 is completely sealed.

[0036] In actual use, the sealed chamber 1, the chamber cover 7, and the chromatography detection card 11 are all disposable and can be scrapped after one use. However, there may be extreme situations where the chromatography detection card 11 needs to be removed. In this case, the operator can simply pull off the chamber cover 7. There is a notch 6 on the side of the chamber cover 7 near the first card slot 5. The thumb and forefinger can pinch the notch 6 to pull out the chamber cover 7.
