[0027] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0029] Reference Figures 1 to 6 As shown, this embodiment provides a colloidal gold method integrated detection tube, including: an outer tube body 10, an intermediate tube body 30, an inner tube body 40 and an end cap 50; at least one detection test strip 21 is arranged in the outer tube body 10, preferably multiple, such as four detection test strips 21 in this specific embodiment; using multiple detection test strips 21, the same item can be detected at the same time to ensure accuracy, and multiple items can also be detected. Of course, in other embodiments, the number of detection test strips 21 can also be one, two, or more than two. The intermediate tube body 30 is inserted into the outer tube body 10, and the bottom of the intermediate tube body 30 is provided with a raised central boss 301 and a through hole 302 located on the periphery of the central boss 301, and the through hole 302 is connected to the accommodating space 101 of the outer tube body 10 (i.e., the space for accommodating the detection test strip 21).

[0030] The inner tube body 40 is inserted into the middle tube body 30, and a through bottom opening 401 is formed at the bottom of the inner tube body 40. The inner tube body 40 and the middle tube body 30 are threadedly assembled, and the central boss 301 of the middle tube body 30 is inserted into the bottom opening 401 of the inner tube body 40 to form a sealing fit. The end cap 50 is detachably assembled on the top opening of the inner tube body 40.

[0031] In the colloidal gold integrated detection tube provided in this embodiment, the bottom opening 401 of the inner tube body 40 is sealed by the central boss 301 of the intermediate tube body 30, so that the diluent can be stored in the inner tube body 40 in advance; after collecting the sample, the end cap 50 is opened, and the sample is immersed in the diluent of the inner tube body 40. At this time, the end cap 50 can be re-covered, and the sample can be diluted by shaking or the like. After the dilution is completed, the inner tube body 40 is rotated to separate the bottom opening 401 of the inner tube body 40 from the central boss 301, and the diluted sample flows into the accommodating space 101 of the outer tube body 10 through the bottom opening 401 and the through hole 302 in turn, thereby contacting the test paper 21 to achieve antigen detection; the sample dilution and antigen detection are integrated; the process is completed inside the detection tube to avoid harm to the human body due to improper operation.

[0032] Furthermore, in this embodiment, a test paper holder 22 is installed in the outer tube body 10, and the test paper holder 22 is located between the outer tube body 10 and the intermediate tube body 30, and the test paper 21 is fixed on the test paper holder 22; thus, it is convenient to fix the test paper 21. Of course, in other embodiments, the test paper 21 can also be fixed on the inner wall of the outer tube body 10.

[0033] Specifically, the outer tube 10 is a transparent tube, which can visually confirm the detection structure. Of course, in other embodiments, a display window can be opened at the position of the outer tube 10 corresponding to the detection test paper 21, but the sealing of the display window must be ensured; or other methods can be used to confirm the detection result of the detection test paper 21.

[0034] The intermediate tube body 30 includes a first tube section 31 inserted into the outer tube body 10 and a first tube head 32 abutting against the tube mouth of the outer tube body 10; the central boss 301 and the through hole 302 are arranged at the bottom of the first tube section 31. Such arrangement facilitates the positioning and installation of the intermediate tube body 30 and the outer tube body 10, and the installation position is more accurate. Of course, in other embodiments, the structure of the intermediate tube body 30 is not limited to this.

[0035] Meanwhile, the inner tube body 40 includes a second tube section 41 inserted into the first tube section 31 and a second tube head 44 protruding from the first tube head 32; the bottom opening 401 is formed at the bottom of the second tube section 41, and the second tube head 44 includes a screw cap 42 covering the outside of the first tube head 32 and a third tube section 43 protruding from the screw cap 42, and the screw cap 42 is provided with raised ribs, which is convenient for holding and rotating to operate the inner tube body 40 to screw in or out. The second tube section 41 and the third tube section 43 are connected, and the top opening is formed at the top of the third tube head 43; the end cap 50 covers the top of the third tube head 43. Such a configuration facilitates the operation of opening the end cap 50 and screwing out the inner tube body 40, and the structure is simple. Of course, in other embodiments, the structure of the inner tube body 40 is not limited to this, such as not using a structure of the screw cap 42, etc.

[0036] Furthermore, the screw cap 42 of the inner tube body 40 forms a limiting cooperation with the first tube head 32 of the intermediate tube body 30. Specifically, in the present embodiment, the screw cap 42 of the inner tube body 40 has a hook 421 extending inwardly, and the top protrusion of the first tube head 32 has a limiting step 321. When the inner tube body 40 is unscrewed and upwardly separated from the intermediate tube body 30, the upward movement distance of the inner tube body 40 is limited by the cooperation between the hook 421 and the limiting step 321; that is, when the inner tube body 40 is unscrewed, it moves upward relative to the intermediate tube body 30, and when it moves upward to the point where the hook 421 is stuck on the limiting step 321, it cannot continue to move upward and separate; before this, the center boss 301 is separated from the bottom opening 401.

[0037] Specifically, in this embodiment, the inner wall of the intermediate tube body 30 is formed with an internal thread 311, and the bottom outer wall of the inner tube body 40 is provided with an external thread 411, and the inner tube body 40 is threadedly connected by the external thread 411 of the bottom outer wall cooperating with the internal thread 311 of the inner wall of the intermediate tube body 30. Such a configuration does not affect the sealing cooperation between the central boss 301 and the bottom opening 401. Of course, in other embodiments, the position of the threaded connection structure of the inner tube body 40 and the intermediate tube body 30 is not limited to this, such as the external thread can be provided on the central boss 301, and the internal thread cooperating therewith can be provided on the inner wall of the bottom opening 401.

[0038] At the same time, the inner wall of the intermediate tube body 30 and the outer wall of the inner tube body 40 are sealed by a sealing ring 60 to prevent the diluent in the inner tube body 40 from leaking through the gap between the intermediate tube body 30 and the inner tube body 40 when flowing out from the bottom opening 401, thereby improving safety.

[0039] Specifically, in this embodiment, the end cap 50 is a nut, and the end cap 50 is threadedly connected with the inner tube body 40 and assembled on the top opening of the inner tube body 40. As shown in the figure, the third tube section 43 of the inner tube body 40 is provided with an external thread 412, and the external thread 412 is used to be threadedly matched with the end cap 50. The installation of the nut 50 adopts a threaded connection method, which has a simple structure and is easy to operate. More preferably, the tightening direction of the end cap 50 on the inner tube body 40 is opposite to the tightening direction of the inner tube body 40 on the intermediate tube body 30, such as the end cap 50 is screwed on the inner tube body 40 clockwise, and the inner tube body 40 is screwed on the intermediate tube body 30 counterclockwise; to prevent the inner tube body 40 from rotating together when the end cap 50 is unscrewed, causing the bottom opening 401 to be opened.
