In some embodiments, after the sampling swab 300 is placed in the first tube 100, in order to maintain the activity of the virus on the sampling swab 300, the sampling swab 300 is contacted and soaked in the preserving fluid 211 for a period of time, i.e., the first tube 100 is connected to the second tube 200, the first storage cavity 110 is communicated with the second storage cavity 210, and the preserving fluid 211 is transferred from the second storage cavity 210 to the first storage cavity 110, and wets the sampling swab 300 in the first storage cavity 110. Thus, referring to fig. 1, the piercing tube 130 is provided at one end of the first tube 100 where the first connection portion 120 is located, the communication portion 240 is provided at one end of the second tube 200 where the second connection portion 220 is located, and the contact portion 250 is provided at one end of the second tube 200 where the third connection portion 230 is located.

Specifically, referring to fig. 2, the puncture tube 130 includes a hard cylindrical protrusion, a small hole is formed at the bottom end of the protrusion, and the preservation solution 211 can flow into or out of the first tube 100 through the small hole, referring to fig. 3, the communicating part 240 includes a rubber body disposed at one end of the second tube 200 where the second connecting part 220 is located, and the rubber body has a large area and a small thickness, so that when the first tube 100 and the second tube 200 are connected through the first connecting part 120 and the second connecting part 220, the puncture tube 130 can puncture the rubber body, thereby communicating the first storage cavity 110 and the second storage cavity 210; the abutting portion 250 includes a rubber body at one end of the second tube 200 where the third connection portion 230 is located, and has a small area and a large thickness, so that when the first tube 100 and the second tube 200 are connected to each other through the first connection portion 120 and the third connection portion 230, the puncture tube 130 abuts against the rubber body and enters a part of the rubber body of the abutting portion 250, and thus the puncture tube 130 does not move relative to the abutting portion 250, and there is a risk that the virus-containing preservation solution 211 leaks.

After the sampling swab 300 is placed in the first tube 100, in order to maintain the activity of the virus on the sampling swab 300, the sampling swab 300 needs to be contacted and soaked in the preservation solution 211 for a period of time, referring to fig. 4 and 5, the first tube 100 and the second tube 200 are connected into a whole by the first connection part 120 and the second connection part 220 being in threaded connection, and the piercing tube 130 of the first tube 100 pierces the communication part 240 of the second tube 200, thereby communicating the first storage chamber 110 with the second storage chamber 210; referring to fig. 6, the first tube 100 and the second tube 200 are turned upside down, so that the preservation solution 211 in the second tube 200 flows into the first tube 100 through the small hole of the puncture tube 130, and the sampling swab 300 is soaked for a period of time, and then the positions of the first tube 100 and the second tube 200 are turned upside down once, that is, as shown in fig. 7, the preservation solution 211 in which the virus on the sampling swab 300 is dissolved flows back to the second tube 200 from the first tube 100, that is, the sampling swab 300 is separated from the preservation solution 211 in which the virus is absorbed, thereby solving the problem that the impurities may affect the subsequent detection result. In order to avoid the poor virus collection effect of the preservation solution 211, the above operations can be repeated several times, so that the preservation solution 211 can fully absorb the viruses on the sampling swab 300.

After the preservation solution 211 that has absorbed the virus on the sampling swab 300 completely flows back to the second tube 200, the first connection part 120 and the second connection part 220 are unscrewed, thereby separating the first tubular body 100 from the second tubular body 200, turning the first tubular body 100 upside down, and the second tube 200 is placed above the first tube 100, the third connection portion 230 of the second tube 200 is threadedly connected with the first connection portion 120 of the first tube 100, that is, as shown in fig. 8, the second tube 200 and the first tube 100 are connected by the first connection portion 120 and the third connection portion 230, and the puncture tube 130 of the first tube 100 abuts against the abutment portion 250 of the second tube 200, so that the puncture tube 130 does not move relative to the abutment portion 250, and the risk of leakage of the virus-containing preservation solution 211 is prevented, and the screw connection between the first connection portion 120 and the third connection portion 230 is tightened, and the first tube 100 and the second tube 200 are connected more firmly. At this time, the communicating portion 240 of the second tube 200 is disposed above and exposed to the external environment, thereby facilitating the syringe to suck the preservation solution 211 for virus detection.

In some embodiments, in order to facilitate the preservation fluid 211 to flow out of the first tube 100, the bottom of the first tube 100 is configured to be an outwardly convex arc surface, and specifically, referring to fig. 5, the preservation fluid 211 after soaking the sampling swab 300 flows out of the small hole of the puncture tube 130 of the first tube 100, so that the bottom of the first tube 100 is configured to be an arc shape in which the tube wall gradually sinks inwards, that is, the preservation fluid 211 does not accumulate fluid on the tube wall of the first tube 100, thereby causing a safety hazard.

It can be understood that, in order to facilitate the absorption and transfer of the preservation solution 211 with viruses from the second tube 200, the end of the second tube 200 where the abutting portion 250 is located is an outwardly convex arc surface, specifically, referring to fig. 8, the bottom of the second tube 200 is an arc with a gradually sinking tube wall, that is, the preservation solution 211 does not accumulate liquid on the tube wall of the second tube 200, thereby causing a safety hazard.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
