Problems solved by technology

[0002] Due to the strong infectivity of the new coronavirus pneumonia virus, special attention should be paid to avoid cross-infection when collecting specimens. During the detection of blood or secretion samples, it is necessary to extract the sample liquid into a nucleic acid test tube, and then centrifuge to make the nucleic acid in the sample liquid Separation; however, prior art tubes do not have caps that can be locked, and after the sample is loaded and snapped through the caps, the caps can be easily removed, making it impossible to tell if the caps of multiple tubes fall off Which tube cap has been matched with which test tube, when the tube cap is fastened again, it is easy to make mistakes and affect the test results

Embodiment 1

[0040] like Figure 1-9 As shown, the improved new coronavirus nucleic acid virus preservation test tube includes a test tube body 1, a tearing piece 2, a stepped connecting tube 3, a tube cap assembly 4 and an anti-opening stopper assembly 5;

[0041] The top of the test tube body 1 is sealed and inserted into the lower section of the stepped connecting tube 3 , and the lower section of the stepped connecting tube 3 and the test tube body 1 are fixedly connected through the tearing piece 2 . ;

[0042]The upper pipe body of the stepped connecting pipe 3 is matched and connected to the inner side of the pipe cap assembly 4 so as to be blocked by the pipe cap assembly 4; the inner diameter of the upper pipe body of the stepped connecting pipe 3 is smaller than that of the stepped connecting pipe 3 The inner diameter of the lower pipe body of the connecting pipe 3;

[0043] The anti-opening blocking assembly 5 is matched and connected to the inner side of the pipe cap assembly...

Embodiment 2

[0048] like Figure 1-9 As shown, the cap assembly 4 includes a cap body 401 and a central vertical pipe 402; one end of the cap body 401 is open and one end is closed, and the inner side of the open end of the cap body 401 is threadedly connected to the stepped connecting pipe The upper pipe body of 3; the center standpipe 402 is fixed at the center of the inside of the pipe cap body 401, and the axis of the pipe cap body 401 is collinear with the axis of the center standpipe 402; the center standpipe 402 is located on the inner side of the stepped connecting pipe 3; the cap body 401 can be connected to the outside of the upper section of the stepped connecting pipe 3 by turning the cap body 401, and the central vertical pipe 402 is controlled to be inserted into the inside of the stepped connecting pipe 3 to increase the The stability of the connection between the pipe cap assembly 4 and the stepped connecting pipe 3 .

[0049] One end of the anti-opening blocking assembly ...

Embodiment 3

[0055] like Figure 1-9 As shown, the anti-opening blocking assembly 5 includes a flip blocking rod 501, a push-pull sliding shaft 502, an inner and outer sliding rod 503, an inclined connecting rod 504, a sliding plate 505, a guide vertical shaft 506, a connecting seat 507 and a tensioning spring 508;

[0056] One end of the guide vertical shaft 506 is provided with an adapter seat 507, and the adapter seat 507 is glued to the center of the inner side surface of the cap body 401; the guide vertical shaft 506 is located on the inner side of the central vertical pipe 402, and The axis of the guide vertical shaft 506 is collinear with the axis of the central vertical pipe 402 ; the sliding plate 505 is slidably fitted in the middle of the guide vertical shaft 506 ; the outer side of the sliding plate 505 evenly rotates and connects multiple One end of the inclined connecting rod 504, the other ends of the plurality of inclined connecting rods 504 are respectively connected to t...

Abstract

The present invention relates to the technical field of test tubes, and more particularly, to an improved new coronavirus nucleic acid virus preservation test tube, comprising a test tube body, a tearing piece, a stepped connecting tube, a tube cap assembly and an anti-opening stopper assembly; The top is sealed and plugged into the lower section of the stepped connecting tube, and the lower section of the stepped connecting tube and the test tube body are fixedly connected through the tearing piece; the upper section of the stepped connecting tube is connected. The inner diameter of the upper pipe body of the stepped connecting pipe is smaller than the inner diameter of the lower pipe body of the stepped connecting pipe; After the cap assembly and the ladder connecting tube are connected and installed, they can form a locking structure that cannot be opened from the outside, so that the cap assembly cannot be opened from the outside, preventing the staff from misoperating and covering the wrong cap assembly or someone concealing the truth in order to avoid nucleic acid detection. The body of the test tube from which the sample was collected.

Description

technical field [0001] The present invention relates to the technical field of test tubes, and more particularly, to an improved test tube for preservation of new coronavirus nucleic acid. Background technique [0002] Due to the strong contagiousness of the new coronavirus pneumonia virus, special attention should be paid to avoid cross-infection when collecting specimens. During the detection of blood or secretion samples, it is necessary to extract the sample liquid into a nucleic acid test tube, and then centrifuge to make the nucleic acid in the sample liquid. However, the test tubes in the prior art do not have caps that can be locked. After the sample is loaded and the caps are fastened, the caps can be easily removed. If the caps of multiple test tubes are dropped, it cannot be distinguished. Which tube cap has been matched with which test tube, when the tube cap is re-fastened, errors are prone to occur, which will affect the test results. SUMMARY OF THE INVENTION...
