Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical testing supplies, in particular to a sealing structure of a disease screening test tube. Background Art
[0002] Test tubes are extremely commonly used testing aids in medicine. Compared to going to the hospital for systematic sampling and testing, which requires a long wait for test results, test tubes are easy to use and allow people to conduct preliminary screening for diseases at home, which is convenient for use. Simple initial examinations of diseases can also be performed in the hospital, without the need for in-depth testing, simplifying the testing process. However, the test tubes currently on the market generally consist of a sampling cotton swab, a rubber-tipped dropper filled with reagents, and a test cartridge. People need to use the sampling cotton swab to take a sample of body fluids, feces, etc., then put it into the rubber-tipped dropper to mix the reagents, and then drop it into the test cartridge to wait for the results. Although this method is faster than in-depth testing in the hospital, the body fluids, feces, etc. samples have an odor during the testing process, which will greatly affect people's user experience. In the process of mixing the sample and reagent, the reagent may leak out of the rubber tube, which is not conducive to use. Utility Model Content
[0003] In view of the above shortcomings, the purpose of the present invention is to provide a sealing structure for a disease screening test tube, which is conducive to reagent filling and sealing. After the lid is closed, it has good sealing performance, does not leak sample odor and reagents, effectively prevents odor, and is convenient for people to use.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:
[0005] A sealing structure for a disease screening test tube includes a test tube body and a lid that covers the test tube body. The lid and the test tube body are provided with a first sealing structure.

[0007] As a further improvement of the present invention, the cover includes a cap and a cover body integrally formed under the cap, the first sealing ring is arranged on the outside of the middle part of the cover body, the second sealing ring is arranged on the outside of the lower end of the cover body, and the cover body is placed in the upper end of the test tube body.
[0008] As a further improvement of the present invention, a cover insertion groove for inserting the cover body is opened at the upper end of the test tube body, and the first sealing embedding groove is arranged on the inner side wall of the cover insertion groove.
[0009] As a further improvement of the present invention, an insertion ring platform is provided outwardly around the upper end of the cover insertion groove, and the lower end of the cover cap is inserted into the insertion ring platform.
[0010] As a further improvement of the present invention, a first covering guide surface is formed at the connection between the insertion ring platform and the covering insertion groove, which extends obliquely from the upper outside to the lower inside, and a second covering guide surface is formed at the connection between the cover cap and the cover body, which extends obliquely from the upper outside to the lower inside and matches the first covering guide surface.

[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0027] Please refer to Figures 1 to 4 The present invention provides a sealing structure for a disease screening test tube, comprising a test tube body 1 and a lid 2 covering the test tube body 1. A first sealing structure 3 is provided on the lid 2 and the test tube body 1. The first sealing structure 3 includes a first sealing ring 31 formed on the outside of the middle portion of the lid 2 and pressed against the inner wall of the test tube body 1 when the lid 2 is closed, and a second sealing ring 32 formed on the outside of the lower end of the lid 2 and pressed against the inner wall of the test tube body 1 when the lid 2 is closed. Both the first sealing ring 31 and the second sealing ring 32 form an interference fit with the inner wall of the test tube body 1.
[0028] When the present sealing structure is needed to seal the test tube body 1 for testing, the cap 2 only needs to be aligned with the upper end of the test tube body 1 and inserted, so that the first sealing ring 31 and the second sealing ring 32 press against the inner wall of the test tube body 1. Because the first sealing ring 31 and the second sealing ring 32 form an interference fit with the inner wall of the test tube body 1, the first sealing ring 31 and the second sealing ring 32 tightly contact the inner wall of the test tube body 1 without external force after the cap is closed and cannot be separated. The structural arrangement of the two sealing rings improves the sealing performance of the test tube body 1, prevents the leakage of sample odor and reagents, effectively prevents odor, and facilitates human use.
[0029] In order to further improve the sealing performance of this sealing mechanism, Figure 2 and Figure 4 As shown, the first sealing structure 3 also includes a first sealing embedding groove 33 formed on the inner wall of the test tube and matching the first sealing ring 31. When the lid 2 is closed on the test tube body 1, the first sealing ring 31 moves in the test tube body 1 until it is placed in the first sealing embedding groove 33. The first sealing ring 31 and the first sealing embedding groove 33 are interference fit, so that the first sealing ring 31 is tightly pressed in the first sealing embedding groove 33 and cannot be separated without external force, thereby further improving the sealing performance of the sealing structure, preventing the leakage of sample odor and reagents, effectively preventing odor, and facilitating human use.
[0030] Regarding the specific structural setting of the cover 2, as shown in FIG. Figures 1 to 4 As shown, the lid 2 comprises a cap 21 and a cover body 22 integrally formed below the cap 21. A first sealing ring 31 is disposed on the outer side of the middle portion of the cap body 22, and a second sealing ring 32 is disposed on the outer side of the lower end of the cap body 22. The cap body 22 is inserted into the upper end of the test tube body 1. The diameter of the cap body 22 matches the diameter of the test tube body 1, facilitating insertion of the cap body 22 into the test tube body 1 and sealing the test tube body 1, preventing odor and reagent leakage and facilitating user use. The diameter of the cap 21 is larger than the diameters of the cap body 22 and the test tube body 1. When the cap 2 is precisely fitted onto the test tube body, the lower end of the cap 21 presses against the upper end of the test tube body 1, preventing the entire cap 2 from becoming embedded in the test tube and becoming inadvertently unable to be removed, thus facilitating user use.
[0031] Regarding the specific method of placing the cover 22 into the test tube body 1, Figure 2 and Figure 4As shown, the upper end of the test tube body 1 is provided with a covering insertion groove 11 for the cover body 22 to be inserted into. The first sealing insertion groove 33 is provided on the inner side wall of the covering insertion groove 11. When the lid 2 is covered on the test tube body 1, the cover body 22 is correspondingly inserted into the covering insertion groove 11, and the first sealing ring 31 thereon is correspondingly pressed into the first sealing insertion groove 33. The two are matched, which helps to improve the sealing degree of the sealing structure.
[0032] In order to limit the position of the cover 2 and improve the efficiency and accuracy of the cover 2 covering the test tube body 1, as shown in FIG. Figures 1 to 2 as well as Figure 4 As shown, an insertion ring 12 is provided outwardly around the upper end of the cover insertion groove 11, and the lower end of the cover cap 21 is inserted into the insertion ring 12, thereby effectively limiting the covering position of the cover 2. Under the limiting effect of the insertion ring 12, the efficiency and accuracy of the cover 2 covering the test tube body 1 can be effectively improved.
[0033] In order to further improve the closing accuracy and efficiency of the lid 2, as Figure 2 and Figure 4 As shown, a first covering guide surface 13 extending obliquely from the upper outside to the lower inside is formed at the connection between the insertion ring 12 and the covering insertion groove 11. A second covering guide surface 23 extending obliquely from the upper outside to the lower inside and matching the first covering guide surface 13 is formed at the connection between the cap 21 and the cover body 22. When the lid 2 is covered on the test tube body 1, the lower end of the cover body 22 is first guided by the oblique first covering guide surface 13, thereby more easily and accurately entering the covering insertion groove 11. When the lid 2 is covered in place, the second covering guide surface 23 abuts against the first covering guide surface 13, and the two guide each other, so that the lid 2 is more tightly covered on the test tube body 1, further improving the covering accuracy and efficiency of the lid 2.
[0034] Preferably, in order to make the cover 22 better used, as Figures 1 to 4 As shown, the cover 2 further includes a handle 24 provided on the outer side of the cap 21 , and people can better operate the cover 2 (close or remove the cover 2 from the test tube body 1 ) through the handle 24 , thereby improving people's user experience.
[0035] Preferably, Figure 1 As shown, the insertion ring 12 is further formed with a handle clearance groove 25 for accommodating the handle 24 . When the lid 2 is closed on the test tube body 1 , the handle 24 is placed in the handle clearance groove 25 , thereby limiting the position of the handle 24 and allowing the lid 2 to be more accurately closed on the test tube body 1 .
[0036] Preferably, Figures 1 to 4 As shown, in order to prevent the cover 2 from being lost when not in use, a connecting strip is provided between the cover 2 and the test tube body 1. The cover 2 and the test tube body 1 are connected by the connecting strip, thereby effectively preventing the cover 2 from being lost when not in use and facilitating use.
[0037] like Figures 1 to 2 as well as Figure 4 As shown, the sealing structure further includes a second sealing structure 4 disposed within the test tube body 1. The second sealing structure 4 includes a sealing tube 41 disposed within the test tube body 1 and a sealing paper 42 disposed at the upper end of the sealing tube 41. The sealing paper 42 seals the sealing tube 41, thereby effectively ensuring that the reagent in the sealing tube 41 will not be contaminated before use, thereby improving the accuracy of the test.
[0038] Preferably, the sealing paper 42 is aluminum foil, which is cheap and easy to process, effectively reducing production costs, and has moisture-proof, airtight, light-shielding and other properties, effectively sealing the reagents in the sealed tube 41, thereby effectively ensuring that the reagents in the sealed tube 41 will not be contaminated before being used, thereby improving the accuracy of detection.
[0039] Regarding the specific structural setting of the sealing paper 42, as shown in FIG. Figure 1 As shown, the sealing paper 42 is in the shape of a teardrop as a whole, and its rounded end is sealed on the sealing tube 41 to ensure the sealing of the sealing tube 41. Its pointed end extends out of the test tube body 1, so that people can hold the pointed end to peel off the sealing paper 42 as a whole and use the reagent.
[0040] Preferably, Figure 2 and Figure 4 As shown, in order to better fill the reagent into the sealing tube 41 and better pressurize the sealing paper 42 on the sealing tube 41, the height of the sealing tube 41 is higher than the height of the test tube body 1, thereby facilitating the mechanical positioning and processing of the sealing tube 41, so that the reagent can be better filled into the sealing tube 41 and the sealing paper 42 can be better pressurized on the sealing tube 41, thereby improving the efficiency of the sealing structure.
[0041] It should be noted that the sealing structure of the disease screening test tube disclosed in this utility model is an improvement to a specific structure, and the specific control method is not the innovation of this utility model. The reagents, aluminum foil, and other components involved in this utility model can be commonly used standard parts or components known to those skilled in the art. Their structure, principles, and control methods are all known to those skilled in the art through technical manuals or routine experimental methods.
[0042] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are within the scope of protection of the present invention.
