[0002] The virus sampling tube is a specimen transport tube used for virus sampling. It can be used for sampling various influenza viruses and hand, foot and mouth virus. It can store nasopharyngeal swab specimens and facilitate transportation to the testing site for testing. During the transportation of the virus sampling tube, it is necessary to ensure that the sample does not leak during transportation to avoid the leakage of pathogenic substances.

[0003] In the prior art, when sampling virus tubes, when conducting large-scale testing in the laboratory, the operations of opening the cover and closing the cover after sampling are time-consuming and laborious; the sampling tubes are generally sealed with screw caps, and the sealing effect is not good; the sampling tubes are large in size, which is not convenient for storing small-volume samples. Summary of the invention

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1-5 , the present invention provides a technical solution:

[0025] The invention discloses a virus sampling tube, comprising a sampling tube body 1. The upper end of the sampling tube body 1 is connected with a screw cover 2. The screw cover 2 can be removed from the sampling tube body 1 by twisting the screw cover 2. A sealing ring 14 is provided at the connection between the top end of the sampling tube body 1 and the inside of the screw cover 2. The sealing ring 14 is bonded to the inner wall of the screw cover 2. The sealing ring 14 plays a sealing role to prevent the collected virus preservation liquid from flowing out. The upper end of the screw cover 2 is connected with a sliding sleeve 3. The inner side walls of the sliding sleeve 3 are both provided with first rubber blocks 4. An annular groove 16 is provided around the middle of the upper end of the screw cover 2. The sliding sleeve 3 is detachably connected to the annular groove 16. The sliding sleeve 3 is held and pulled. Since the first rubber block 4 and the second rubber block 6 are both elastic, under the action of the pulling force, the first rubber block 4 is separated from the second rubber block 6, and the sliding sleeve 3 can be pulled out to pour out the virus liquid in the sampling tube body 1.

[0026] A through hole 9 is provided in the middle of the convex tip 8, and the through hole 9 runs through the middle of the convex tip 8. The sampling tube body 1 is inverted, and the virus liquid in the sampling tube body 1 can flow out from the through hole 9 and the through groove 10 of the convex tip 8. A rubber sealing sleeve 5 is provided on the surface of the convex block 7, and the rubber sealing sleeve 5 is bonded to the convex block 7. The second rubber clamping block 6 is fixedly connected to the two side surfaces of the rubber sealing sleeve 5. The rubber sealing sleeve 5 is in contact with the sliding sleeve 3, so that the connection between the sliding sleeve 3 and the convex block 7 is sealed to prevent the virus liquid from leaking. A through groove 10 is provided at one end of the rubber sealing sleeve 5 relative to the through hole 9, and the middle part of the through groove 10 is connected to the through hole 9. A sleeve foot 17 is provided at the lower end of the middle part of the rubber sealing sleeve 5, and the sleeve foot 17 is integrally connected to the rubber sealing sleeve 5. The sleeve foot 17 is inserted between the middle part of the convex block 7 and the convex tip 8, and the sleeve foot 17 of the rubber sealing sleeve 5 is fixed more firmly.

[0027] A protrusion 7 is provided in the middle of the upper end of the screw cover 2, and the protrusion 7 is integrally connected to the screw cover 2. The protrusion 7 is provided in the middle of the annular groove 16, and the sliding sleeve 3 is clamped on the protrusion 7. The sliding sleeve 3 is embedded in the annular groove 16. The sliding sleeve 3 is held and pulled to pull the sliding sleeve 3 from the protrusion 7 to sample the virus liquid in the sampling tube body 1. A middle groove 12 is provided in the middle of the protrusion 7, and a convex tip 8 is provided in the middle groove 12. The convex tip 8 is fixedly connected to the inner groove wall of the middle groove 12. The sampling tube body 1 is inverted, and the virus liquid in the sampling tube body 1 can flow out from the through hole 9 of the convex tip 8 and the through groove 10.

[0028] The surface of the screw cap 2 is provided with annular anti-skid patterns 13, and a plurality of anti-skid patterns 13 are evenly distributed on the surface of the screw cap 2. The anti-skid patterns 13 provided on the surface of the screw cap 2 are more convenient when twisting to prevent slipping and falling. The surface of the sampling tube body 1 is provided with sampling scales 15. A 10ml storage tube is used, and the volume of the virus preservation liquid is 3-6ml, which reduces the volume of the sample preservation. The volume of the virus liquid inside the sampling tube body 1 can be observed through the sampling scales 15 on the surface of the sampling tube body 1, and sampling can be performed according to one's own needs, and the sampling is more accurate.

[0029] The inner side wall of the screw cover 2 is provided with a thread 11 , and the sampling tube body 1 is threadedly connected to the inner wall of the screw cover 2 via the thread 11 . The screw cover 2 can be removed from the sampling tube body 1 by twisting the screw cover 2 .

[0030] Specifically, when the sampling tube body 1 is used, a screw cap 2 is threadedly connected to the upper end of the sampling tube body 1, and a sealing ring 14 is arranged at the connection between the inside of the screw cap 2 and the upper end of the sampling tube body 1. The sealing ring 14 plays a sealing role to prevent the collected virus preservation liquid from flowing out. The surface of the screw cap 2 is provided with an anti-slip pattern 13, which is more convenient when twisting to prevent the hand from slipping and falling. When transporting to the laboratory for sampling, the sliding sleeve 3 is held and pulled. Since the first rubber block 4 and the second rubber block 6 are both elastic, under the action of tension, the first rubber block 4 is separated from the second rubber block 6, and the sliding sleeve 3 can be pulled out, and the sampling tube body 1 is inverted, so that the virus liquid in the sampling tube body 1 flows out from the through hole 9 and the through groove 10. The volume of the virus liquid inside the sampling tube body 1 can be observed through the sampling scale 15 on the surface of the sampling tube body 1, and sampling can be performed according to one's own needs, and the sampling is more accurate;

[0031] After the sampling is completed, pick up the sliding sleeve 3 and push the sliding sleeve 3 so that the sliding sleeve 3 is pushed into the annular groove 16, so that the first rubber block 4 and the second rubber block 6 are engaged, and the sliding sleeve 3 can be firmly embedded in the annular groove 16, so that the inner wall of the sliding sleeve 3 fits with the rubber sealing sleeve 5, and the rubber sealing sleeve 5 plays a sealing role to prevent leakage of the virus sampling liquid.
