Technical Field

[0001] The utility model relates to a detection kit, in particular to a detection kit used for a colloidal gold method. Background Art

[0002] A colloidal gold test kit utilizes colloidal gold immunolabeling technology. This kit typically contains a test strip pre-loaded with specific antibodies. When the sample comes into contact with the test strip, the target antigen in the sample binds to the antibodies on the strip, forming an antigen-antibody complex. This complex produces a visible color development at a specific location, thereby determining the presence of the target antigen in the sample.

[0003] On the market, colloidal gold test kits are usually packaged with detection reagents and cotton swabs, and are packaged separately. However, due to the small size of the kits, detection reagents and cotton swabs, it is easy to lose an item during use, or contaminate an item due to improper operation, resulting in a large amount of cost consumption and waste of resources.

[0004] Therefore, it is necessary to design an integrated detection kit for the colloidal gold method. Utility Model Content

[0007] Furthermore, a guide rod is fixedly connected to one side of the detection box, the guide rod is slidably connected to the limit block, an elastic member is wound around the guide rod, and both ends of the elastic member are respectively connected to the limit block and the end of the guide rod.

[0008] Furthermore, an inclined block for guiding the reagent liquid is fixedly connected to one end of the connecting tube close to the detection box.

[0009] Furthermore, a transparent shell is provided outside the detection box and the reagent bottle, and the transparent shell is used to protect the detection box and the reagent bottle.

[0010] Further, the transparent shell is screw-connected with a second screw cap for closing the opening of the transparent shell on one side, and a cotton swab is fixedly connected inside the second screw cap, with one end of the cotton swab extending into the interior of the transparent shell.

[0011] Further, the transparent shell is screw-connected with a second screw cap for closing the opening of the transparent shell on one side, and a cotton swab is fixedly connected inside the second screw cap, with one end of the cotton swab extending into the interior of the transparent shell.

[0012] The utility model has the advantages of the following: 1. The utility model is integrated with the detection box, the reagent bottle and the cotton swab, so that the user can easily complete sample collection, reagent mixing and detection preparation, simplifying the operation steps and improving the detection efficiency, and avoiding the loss or pollution of an article.

DETAILED DESCRIPTION

[0021] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments.

[0022] Embodiment: A detection kit for colloidal gold method, as shown in Figure 2 and Figure 3 , comprising a detection box 2, test paper 3, connecting pipe 4, reagent bottle 5, first screw cap 6 and sealing ring 7, the test paper 3 is fixedly connected inside the detection box 2, the connecting pipe 4 is fixedly connected on one side of the detection box 2, the reagent bottle 5 is movably connected with the connecting pipe 4, the reagent bottle 5 is communicated with the inside of the detection box 2 through the connecting pipe 4, the sealing ring 7 is fixedly connected on one side of the reagent bottle 5 close to the connecting pipe 4, and the first screw cap 6 for closing the reagent bottle 5 is threadedly connected on the end of the reagent bottle 5 away from the detection box 2, wherein, in the process of pressing the reagent bottle 5 to make the reagent bottle 5 slide inward, the sealing ring 7 in the reagent bottle 5 slides downward and is extruded by the connecting pipe 4, so that the connecting pipe 4 extends into the inside of the reagent bottle 5 through the sealing ring 7, thereby communicating the reagent bottle 5 with the detection box 2, and the reagent in the reagent bottle 5 enters the inside of the detection box 2 through the connecting pipe 4.

[0023] As shown in Figure 4 , the detection box 2 is fixedly connected with a guide rod 8 on one side, the guide rod 8 is slidably connected with a limiting block 9, and an elastic member 10 is wound on the guide rod 8, and the two ends of the elastic member 10 are respectively connected with the limiting block 9 and the end of the guide rod 8, wherein the elastic member 10 is rubber or plastic with elasticity, so that the elastic member 10 can work normally while saving production cost, when the reagent bottle 5 is pressed to make the reagent bottle 5 slide inward, the reagent bottle 5 extrudes and drives the limiting block 9 to slide downward, at this time the elastic member 10 is stretched, the limiting block 9 no longer blocks the reagent bottle 5 from sliding downward, so that the limiting block 9 releases the limiting of the reagent bottle 5 and releases the reagent bottle 5, at this time the elastic member 10 returns to the initial state and drives the limiting block 9 to return to the initial position, the limiting block 9 drives the reagent bottle 5 to slide upward, and the limiting block 9 limits the reagent bottle 5 again, preventing the reagent bottle 5 from moving randomly.

[0024] As shown in Figure 3 , the connecting pipe 4 is fixedly connected with an inclined block 11 for guiding the reagent liquid on one end close to the detection box 2, wherein the design of the inclined block 11 in the inside of the connecting pipe 4 makes the reagent guided by the inclined block 11 after entering the inside of the connecting pipe 4, so that the reagent flows to the inside of the detection box 2 along the inclined surface of the inclined block 11, preventing the reagent from accumulating, thereby ensuring the efficiency of the detection work.

[0025] As shown in Figure 1 and Figure 2As shown, the detection box 2 and the reagent bottle 5 are externally provided with a transparent shell 1, which is used to protect the detection box 2 and the reagent bottle 5. Here, the detection box 2 is fixedly connected with the transparent shell 1, and the reagent bottle 5 is slidingly connected with the transparent shell 1. The design of the transparent shell 1 not only provides protection for the reagent bottle 5 and the detection box 2, thereby improving the service life of the reagent bottle 5 and the detection box 2, but also facilitates the user to observe the internal situation of the device and the detection result.

[0026] As shown in Figure 1 and Figure 2 , the transparent shell 1 is threadedly connected with a second screw cap 12 on one side for closing the opening of the transparent shell 1. The second screw cap 12 is fixedly connected with a cotton swab 13 inside. One end of the cotton swab 13 extends into the inside of the transparent shell 1. Here, counterclockwise twisting of the second screw cap 12 makes the second screw cap 12 no longer connected with the transparent shell 1, so that the cotton swab 13 can be taken out.

[0027] As shown in Figure 1 and Figure 5 , the transparent shell 1 is fixedly connected with a fixed frame 14 on the side opposite to the second screw cap 12. The fixed frame 14 is slidingly connected with a placing frame 15 for storing a lancet. Here, when blood sampling is needed, the placing frame 15 can be pushed outward to be unclosed, and then the lancet in the placing frame 15 can be taken out for blood sampling, thereby improving the flexibility of the device.

[0028] The device is commonly used for detecting whether the human body carries new coronavirus and malaria virus, etc. When in use, the second screw cap 12 is counterclockwise twisted to make the second screw cap 12 no longer connected with the transparent shell 1, so that the cotton swab 13 can be taken out. Then the cotton swab 13 is extended into the nasal cavity and slightly rotated to obtain a nasal swab sample. Then the first screw cap 6 is counterclockwise twisted to make the first screw cap 6 no longer close the reagent bottle 5. The cotton swab 13 is extended into the reagent bottle 5. Then the second screw cap 12 is clockwise twisted to make the second screw cap 12 connected with the reagent bottle 5 and close the reagent bottle 5. Then the device is slightly shaken to make the reagent in the reagent bottle 5 fully react with the nasal swab sample. Finally, the second screw cap 12 is pressed inward to make the second screw cap 12 drive the reagent bottle 5 to slide inward. In the process of the reagent bottle 5 sliding inward, the sealing ring 7 in the reagent bottle 5 slides downward and is extruded by the connecting pipe 4, so that the connecting pipe 4 extends into the inside of the reagent bottle 5 through the sealing ring 7, thereby connecting the reagent bottle 5 with the detection box 2. The reagent in the reagent bottle 5 enters the inside of the detection box 2 through the connecting pipe 4. Then the test paper 3 in the detection box 2 absorbs the reagent by capillary action. The test paper 3 reacts with the reagent and produces a visible color detection result at a specific position. Thus, the detection work is completed.

[0029] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
