Technical Field
[0001] The utility model relates to the technical field of nucleic acid detection collection tubes, in particular to an alcohol-free nucleic acid detection collection tube. Background Technique
[0002] Nucleic acid detection is to determine whether a patient is infected with COVID-19 by detecting whether there is nucleic acid of foreign invading viruses in the patient's respiratory samples, blood or feces. Nucleic acid detection requires five steps: sampling, sample retention, preservation, nucleic acid extraction, and computer detection. After swabbing the nasal cavity or the posterior pharyngeal wall and bilateral pharyngeal tonsils with a nasal swab or pharyngeal swab, medical staff need to retain the sample, immerse the swab head in the cell preservation solution in the collection tube, and immediately tighten the tube cap after cutting off the tail.
[0003] The existing technology has the following problems:
[0004] The existing alcohol-free nucleic acid detection collection tube has a simple structure. It simply seals the swab head in the collection tube. When the cell preservation solution in the collection tube is subsequently transferred for detection, the cotton fibers in the cell preservation solution will cause unnecessary influence on the transfer of the cell preservation solution. Content of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the utility model provides an alcohol-free nucleic acid detection collection tube, which solves the problem of inconvenient transfer of the cell preservation solution existing nowadays.
[0006] To achieve the above object, the utility model provides the following technical solution: An alcohol-free nucleic acid detection collection tube, including a collection tube body, a snap ring is arranged on the collection tube body, and a pressing block is connected to the outside of the snap ring. A sliding groove is opened on the inner wall of the pressing block, and a spring is arranged in the sliding groove. A sealing gasket is arranged on the upper surface of the pressing block, and a first thread groove is opened at the upper end of the collection tube body. A connecting block is connected to the first thread groove, and a second thread groove is opened at the upper end of the connecting block. A first groove is opened on the lower bottom surface of the connecting block, and a clamping block is arranged in the first groove. A sealing ring is arranged on the outer wall of the clamping block, and a filter screen is arranged at the center of the clamping block. A second groove is opened above the first groove, and a sealing block is arranged in the second groove. A sealing cover is connected above the connecting block, and a third groove is opened on the lower bottom surface of the sealing cover.
[0007] As a preferred technical solution of the utility model, the pressing block is of an annular structure, and the pressing block is slidably connected to the collection tube body through the sliding groove.
[0008] As a preferred technical solution of the utility model, the connecting block is threadedly connected to the collection tube body through the first thread groove, and the sealing cover is threadedly connected to the connecting block through the second thread groove.
[0009] As a preferred technical solution of the present utility model, the outer diameter of the clamping block matches the inner diameter of the main body of the collection tube, and the clamping block is a hollow columnar structure.
[0010] As a preferred technical solution of the present utility model, the first groove and the second groove are communicated, and the outer diameter of the sealing block matches the inner diameter of the second groove.
[0011] As a preferred technical solution of the present utility model, anti-slip patterns are provided on the outer side walls of the connecting block and the sealing cover, and the outer diameters of the connecting block and the sealing cover are the same.
[0012] Compared with the prior art, the present utility model provides an alcohol-free nucleic acid detection collection tube, which has the following beneficial effects:
[0013] 1. For this alcohol-free nucleic acid detection collection tube, by providing a connecting block and a sealing cover at the upper end of the main body of the collection tube, arranging a clamping block and a sealing block in the connecting block, and setting a filter screen on the clamping block. During use, after cutting off the tail of the swab head, it is placed into the main body of the collection tube, and then the connecting block and the sealing cover are covered. When it is necessary to transfer the cell preservation solution, just open the sealing cover and then remove the sealing block. This design can realize the filtration of the cell preservation solution by using the filter screen to prevent the cotton fibers and cotton fiber residues of the swab head from being transferred together with the cell preservation solution. Through this design, it is very convenient for the staff to transfer and detect the cell preservation solution in the main body of the collection tube.
[0014] 2. For this alcohol-free nucleic acid detection collection tube, by providing a snap ring and a pressing block on the main body of the collection tube, opening a sliding groove on the inner wall of the pressing block, arranging a spring in the sliding groove, and providing a sealing gasket on the upper surface of the pressing block. During use, the connecting block is connected to the first threaded groove and the pressing block is pressed downward. The acting force of the spring can make the sealing gasket keep in contact with the lower bottom surface of the connecting block, thus avoiding the phenomenon that the cell preservation solution in the main body of the collection tube leaks due to the connecting block not being tightened or loosening during threaded connection. Through this design, the sealing performance of the device can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS
