Description

Technical Field

[0001] This utility model relates to the field of detection card technology, specifically a qualitative detection card for urine samples. Background Technology

[0002] Qualitative test cards for urine samples are mainly used for rapid screening of the presence of specific drugs or metabolites (such as methamphetamine, ketamine, morphine, etc.) in urine. The principle is based on competitive immunochromatography combined with monoclonal antibody technology to achieve highly specific detection.

[0003] A search revealed a patent, CN214895319U, which discloses a urine test card for rapid drug testing. The test box has a sliding groove on one side of its interior, a sliding plate on one side of the inner wall of the sliding groove, a test card on the top side of the sliding plate, a test port on the top side of the test box, a display window on the top side of the test box near the test port, an outer plate fixedly installed on the outer end of the sliding plate, and a drying mechanism connected to the outer end of the test box. A test area is provided on the top side of the test card corresponding to the test port. This utility model's urine test card for rapid drug testing allows for more precise storage of the test card, improves the accuracy of rapid drug detection, effectively enhances the practicality of the overall device, and brings better application prospects.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the aforementioned comparative document, the test card is placed on a sliding plate, which is then slid into the test box. During subsequent testing, a urine sample is added through the test port and observed through the display window. However, in actual operation, since the entire test card is pre-assembled, it is removed when needed. During long-term storage, particulate impurities from the outside air may fall onto the test card through the test port and display window, potentially affecting the accuracy of qualitative testing of urine. Therefore, there is an urgent need in the art to improve the urine test card to address the shortcomings of the existing technology. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a qualitative detection card for urine samples, improving the accuracy of subsequent testing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a qualitative detection card for urine samples, comprising a suitable detection box and a box cover. The detection box contains a detection paperboard for detection, and a movable plate that can move within the detection box is provided. The detection paperboard is mounted on the upper part of the movable plate. Two connecting rods penetrating the detection box are fixedly installed on the side of the movable plate. A pull rod is fixedly installed between the outer ends of the two connecting rods. The detection paperboard has a detection area and a display area. The box cover has a through-hole for adding a sample and an observation port that are adapted to the detection and display areas. When the movable plate moves to one side of the detection box, the detection area and the display area completely avoid the sample and observation ports.

[0008] Preferably, a sealing strip is fixedly installed on the upper part of the movable plate, with one side abutting against the side of the box cover, and the sealing strip is elastic.

[0009] Preferably, a number of snap-fit ​​posts are fixedly installed on the movable plate, and a number of snap-fit ​​holes adapted to the snap-fit ​​posts are opened through both ends of the test cardboard.

[0010] Preferably, both the sample inlet and the observation port are provided with a sealing plate that can be opened and closed, and the inner sidewalls of both the sample inlet and the observation port are provided with a displacement groove that is adapted to the sealing plate, and the displacement groove extends through one side of the box cover.

[0011] Preferably, a backing plate is fixedly installed on the side of the sealing plate, and the backing plate is pushed to move when the moving plate moves.

[0012] Preferably, the lid and the test box are rotatably connected.

[0013] Preferably, two symmetrical and elastic plates are fixedly installed on one side of the box cover. One side of the elastic plate is provided with a snap-fit ​​protrusion, and the side of the test box is provided with a snap-fit ​​groove that matches the snap-fit ​​protrusion.

[0014] To address the shortcomings of existing technologies, this invention provides a qualitative detection card for urine samples, overcoming these deficiencies. The beneficial effects of this invention are as follows:

[0015] In this invention, the moving plate is moved by pulling the lever. When the test card is not in use, the test cardboard avoids the sample inlet and the observation port, preventing particulate impurities in the air from falling or sticking to the test area or display area of ​​the test cardboard when it is stored or before it is packaged, thus improving the accuracy of subsequent tests.

[0016] In this invention, the snap-fit ​​hole on the test cardboard snaps into the snap-fit ​​post position on the moving plate, which facilitates the installation of the test cardboard.

[0017] In this invention, the upper part of the sealing strip abuts against the lower part of the box cover, and both ends abut against the inner side wall of the test box, ensuring the sealing of the test cardboard after it is placed inside the test box, thus achieving the effects of moisture prevention and dust prevention.

[0018] In this invention, the sample inlet and the observation port are sealed by a sealing plate. Pulling the lever moves the moving plate, which in turn moves the abutment plate. The abutment plate then moves the sealing plate within the displacement groove, thus opening the sample inlet and the observation port. This improves the moisture and dust protection of the test paperboard and makes it easier to use.

[0019] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-5 A qualitative detection card for urine samples includes a matching detection box 1 and a box cover 3. The detection box 1 contains a detection paper 2 for detection. The detection box 1 also contains a movable plate 6 that can move within the detection box 1. The detection paper 2 is mounted on the upper part of the movable plate 6. Two connecting rods 8 that penetrate the detection box 1 are fixedly installed on the side of the movable plate 6. A pull rod 7 is fixedly installed between the outer ends of the two connecting rods 8. The detection paper 2 has a detection area 4 and a display area 5. The box cover 3 has a through-hole for sample application 10 and an observation port 11 that are adapted to the detection area 4 and the display area 5. When the movable plate 6 moves to one side inside the detection box 1, the detection area 4 and the display area 5 completely avoid the sample application port 10 and the observation port 11.

[0029] Specifically, the test paper 2 is mounted on the movable plate 6. When qualitative testing of urine is required, pulling the lever 7 moves the two connecting rods 8, which in turn move the movable plate 6. The movable plate 6 then moves the test paper 2 to the other side of the test paper 2. At this point, the positions of the test area 4 and the display area 5 on the test paper 2 are aligned with the positions of the sample application port 10 and the observation port 11. The urine sample is then added to the test area 4 on the test paper 2 through the sample application port 10. The test area 4 is equipped with a gold-labeled pad. The urine migrates to the gold-labeled pad, dissolving the colloidal gold-labeled antibody. The display area 5 has C-lines and T-lines. If the urine contains MAMP / K... ET / MOR binds to the gold-labeled antibody, inhibiting the reaction between the antibody and the detection line conjugate, resulting in the corresponding T line not showing color. The C line always showing color indicates a valid test. If the C line is showing color and any T line is colorless, it indicates a positive result. If the C line and all T lines are showing color, it indicates a negative result. If the C line is colorless, the test needs to be repeated. The test strip 2 can move within the test box 1. When the test card is not in use, the test strip 2 avoids the sample dispensing port 10 and the observation port 11 to prevent particulate impurities in the air from falling or sticking to the test area 4 or display area 5 on the test strip 2 during storage or before packaging, thus improving the accuracy of subsequent tests.

[0030] As a technical optimization of this utility model, a sealing strip 9 is fixedly installed on the upper part of the movable plate 6, with one side abutting against the side of the box cover 3. The sealing strip 9 is elastic. When the movable plate 6 is located away from the sample inlet 10 and the observation port 11, the upper part of the sealing strip 9 is tightly abutting against the lower part of the box cover 3, and both ends abut against the inner side wall of the test box 1, ensuring the sealing of the test paperboard 2 after it is placed in the test box 1, thus achieving the effect of moisture prevention and dust prevention.

[0031] As a technical optimization of this utility model, a number of snap-fit ​​posts 12 are fixedly installed on the movable plate 6, and a number of snap-fit ​​holes 13 adapted to the snap-fit ​​posts 12 are opened through both ends of the detection paperboard 2. When the detection paperboard 2 is installed, the snap-fit ​​holes 13 on the detection paperboard 2 are snapped into the snap-fit ​​posts 12 on the movable plate 6, which facilitates the installation of the detection paperboard 2.

[0032] As a technical optimization of this utility model, both the sample inlet 10 and the observation port 11 are provided with a sealing plate 14 that can be opened and closed. The inner sidewalls of the sample inlet 10 and the observation port 11 are provided with a displacement groove 15 that is adapted to the sealing plate 14. The displacement groove 15 passes through one side of the box cover 3. A backing plate 16 is fixedly installed on the side of the sealing plate 14. When the moving plate 6 moves, it pushes the backing plate 16 to move. When the test card is not in use, the sample inlet 10 and the observation port 11 are closed by the sealing plate 14. When urine needs to be tested, the pull rod 7 is pulled to move the moving plate 6. When the moving plate 6 moves, it drives the backing plate 16 to move. The backing plate 16 drives the sealing plate 14 to move in the displacement groove 15, which opens the sample inlet 10 and the observation port 11, improves the moisture-proof and dust-proof effect of the test cardboard 2, and facilitates use.

[0033] As a technical optimization of this utility model, the lid 3 and the test box 1 are rotatably connected. Two symmetrical and elastic plates 17 are fixedly installed on one side of the lid 3. One side of the elastic plate 17 is provided with a snap-fit ​​protrusion 18. The test box 1 is provided with a slot 19 that matches the snap-fit ​​protrusion 18 on one side. The lid 3 is opened by rotating, which makes it easier to install the test paperboard 2. After the test paperboard 2 is installed, the lid 3 is rotated, and the snap-fit ​​protrusion 18 on the elastic plate 17 snaps into the slot 19, thus connecting the test box 1 and the lid 3.
