Safe virus preservation tube

Abstract

The utility model relates to the technical field of virus sampling devices, in particular to a safe virus preservation tube. In the sampling process, after sampling is completed through the swab assembly, the swab assembly extends into the pipe assembly, and the swab head of the swab penetrates through the clamping assembly, so that the clamping assembly can clamp the swab rod. After the pipe cover assembly is screwed down, the clamping assembly clamps the swab rod, and therefore the swab swab head can stably stay in the pipe assembly. Due to the fact that the swab assembly is installed on the pipe cover assembly, after the pipe cover assembly covers the pipe fitting assembly in a sealing mode, the whole swab assembly is sealed in the pipe fitting assembly, and the swab rod and the swab swab head are sealed at the same time through the safety type virus preservation pipe. And the problem that the risk of virus diffusion is increased due to improper treatment of the swab rod is avoided. Therefore, the safety of the virus sampling process is ensured.

Description

Technical Field

[0001] This application relates to the technical field of virus sampling devices, and in particular to a safe virus preservation tube. Background Art

[0002] Swab sampling is widely used in the collection of clinical virus specimens. During the swab sampling process, after the cotton swab head of the swab is wiped at the designated part of the subject, the cotton swab head is then placed into a preservation tube containing a virus preservation solution.

[0003] In order to ensure the safety of the sampler and enable the cotton swab head to reach the designated part of the subject smoothly, the length of the swab rod of the swab is usually long. After sampling, usually the swab rod is broken, and the part with the cotton swab head is left in the virus preservation tube. Currently, it is usually the sampler who breaks the swab rod by hand, which not only increases the risk of contaminating the cotton swab head, but also exposes the sampler to the risk of infection. And the swab rod will also be contaminated by the virus during the sampling process. If no special treatment is done, it will increase the risk of virus spread.

[0004] It can be seen that how to ensure the safety of the virus sampling process is a technical problem to be solved urgently. Utility Model Content

[0040] Please refer to Figures 1 to 2 , in some embodiments of the present application, the present application provides a safety-type virus preservation tube 10 for preserving virus samples during sampling by a swab assembly 60. The swab assembly 60 includes a swab rod 61 and a swab cotton tip 62. The swab cotton tip 62 is located at one end of the swab rod 61 and includes: a tube cap assembly 20, a tube member assembly 30, and a clamping assembly 40. The tube cap assembly 20 is used to install the swab assembly 60. The tube member assembly 30 is used to load the swab cotton tip 62. The clamping assembly 40 is used to clamp the swab rod 61. Wherein, during the sampling process, after the swab assembly 60 extends into the tube member assembly 30 and passes through the clamping assembly 40, and the tube cap assembly 20 is tightened, the clamping assembly 40 clamps the swab rod 61.

[0041] During the sampling process, after sampling is completed by the swab assembly 60, the swab assembly 60 is extended into the tube member assembly 30, and the swab cotton tip 62 is made to pass through the clamping assembly 40 so that the clamping assembly 40 can clamp the swab rod 61. After the tube cap assembly 20 is tightened, the clamping assembly 40 clamps the swab rod 61, so that the swab cotton tip 62 can stably stay in the tube member assembly 30. Since the swab assembly 60 is installed on the tube cap assembly 20, when the tube cap assembly 20 caps the tube member assembly 30, the entire swab assembly 60 is sealed in the tube member assembly 30, thereby simultaneously sealing the swab rod 61 and the swab cotton tip 62 by the safety-type virus preservation tube 10 provided by the present application, and avoiding the problem of an increased risk of virus spread caused by improper handling of the swab rod 61. Thus, the safety of the virus sampling process is ensured.

[0042] In some embodiments of the present application, after the clamping assembly 40 clamps the swab rod 61, the tube cap assembly 20 can be further rotated to break the swab rod 61.

[0043] After tightening the tube cap assembly 20, the clamping assembly 40 tightly clamps the swab rod 61, and then fixes the swab rod 61 and the swab cotton tip 62 through the clamping assembly 40. Continuing to turn the tube cap assembly 20, the swab rod 61 is twisted and deformed until the swab rod 61 is broken off. In this way, after the swab assembly 60 is sealed in the pipe fitting assembly 30 by the tube cap assembly 20, the swab rod 61 is broken off to separate the swab rod 61 from the swab cotton tip 62. Breaking off the swab rod 61 in a closed space, on the one hand, avoids the sampler directly contacting the swab assembly 60, thus avoiding the risk of the sampler being infected. On the other hand, after the swab rod 61 is broken off, it is still sealed in the pipe fitting assembly 30, which can effectively avoid the problem of increased risk of virus spread caused by improper handling of the swab rod 61. By breaking off the swab rod 61, the swab rod 61 is separated from the swab cotton tip 62 contaminated with a large amount of virus, so as to separately process the swab rod 61 and the swab cotton tip 62, improving the efficiency and reliability of killing redundant viruses. By separating the swab rod 61 from the swab cotton tip 62, it can also effectively avoid the contamination of the virus preservation solution by the miscellaneous bacteria on the swab rod 61, making the subsequent detection process and detection results more effective.

[0044] In some embodiments of the present application, the pipe fitting assembly 30 includes: a first pipe fitting 31 and a second pipe fitting 32. The first pipe fitting 31 is used to load the swab cotton tip 62. The second pipe fitting 32 is adapted to the tube cap assembly 20. The first pipe fitting 31 is installed in the second pipe fitting 32, and the pipe orifice of the first pipe fitting 31 faces the pipe orifice of the second pipe fitting 32. Among them, the clamping assembly 40 is arranged at the pipe orifice of the first pipe fitting 31.

[0045] After sampling with the swab assembly 60, the swab assembly 60 is inserted into the second pipe fitting 32, and then the swab cotton tip 62 passes through the clamping assembly 40 and is inserted into the first pipe fitting 31. After tightening the tube cap assembly 20, the clamping assembly 40 clamps the swab rod 61 and makes the swab cotton tip 62 stay stably in the first pipe fitting 31. When the swab rod 61 is broken off, the swab rod 61 stays in the second pipe fitting 32, and the second pipe fitting 32 is capped by the tube cap assembly 20 to prevent virus spillage. The swab rod 61 and the swab cotton tip 62 are separately sealed by the first pipe fitting 31 and the second pipe fitting 32, avoiding the virus of the swab cotton tip 62 from contaminating the swab rod 61 and reducing the risk of virus spread.

[0046] In some embodiments of the present application, the clamping assembly 40 includes: a pipe plug assembly 41 and a pushing assembly 50. The pipe plug assembly 41 is adapted to the pipe orifice of the first pipe fitting 31, and the pipe plug assembly 41 includes at least two clamping members 411. The pushing assembly 50 is configured to push the pipe plug assembly 41 into the interior of the first pipe fitting 31, so that the clamping members 411 in the pipe plug assembly 41 approach each other and seal the first pipe fitting 31. Wherein, during the process of the swab assembly 60 extending into the first pipe fitting 31, the swab cotton swab head 62 passes through between the clamping members 411 and then extends into the first pipe fitting 31.

[0047] The first pipe fitting 31 is sealed by the pipe plug assembly 41, thereby preventing the virus preservation liquid in the first pipe fitting 31 from overflowing. During the process of the pipe plug assembly 41 sealing the first pipe fitting 31, the pipe plug assembly 41 is pushed into the interior of the first pipe fitting 31 by the pushing assembly 50, and then the inner wall of the first pipe fitting 31 squeezes the clamping members 411 in the pipe plug assembly 41, so that the clamping members 411 approach each other and clamp the swab rod 61, so that the swab cotton swab head 62 stays in the first pipe fitting 31 and the swab rod 61 stays in the second pipe fitting 32. Thus, the first pipe fitting 31 is sealed by the pipe plug assembly 41 to prevent the virus preservation liquid from overflowing from the first pipe fitting 31 and reduce the risk of virus spread; during the process of the pipe plug assembly 41 sealing the first pipe fitting 31, the swab rod 61 is clamped and the swab cotton swab head 62 and the swab rod 61 are respectively sealed in the first pipe fitting 31 and the second pipe fitting 32 to prevent the virus on the swab cotton swab head 62 from contaminating the swab rod 61 and reduce the risk of virus spread; since the pipe plug assembly 41 tightly clamps the swab rod 61, during the process of continuing to turn the pipe cap assembly 20, the swab rod 61 can be broken off to prevent the sampler from directly contacting the swab assembly 60, thereby avoiding the risk of the sampler being infected.

[0048] In some embodiments of the present application, one end of the pushing assembly 50 abuts against the pipe cap assembly 20, and the other end of the pushing assembly 50 abuts against the pipe plug assembly 41. During the process of turning the pipe cap assembly 20, the pushing assembly 50 pushes the pipe plug assembly 41 to move.

[0049] During the process of screwing the tube cap assembly 20, the tube cap assembly 20 gradually moves towards the other end of the tube fitting assembly 30. During the movement of the tube cap assembly 20, the pushing assembly 50 pushes the tube plug assembly 41 into the first tube fitting 31, and then the inner wall of the first tube fitting 31 squeezes the clamping member 411 in the tube plug assembly 41, so that the clamping members 411 approach each other and clamp the swab rod 61, so that the swab cotton tip 62 stays in the first tube fitting 31 and the swab rod 61 stays in the second tube fitting 32. In this way, the first tube fitting 31 is sealed by the tube plug assembly 41 to prevent the virus preservation liquid from overflowing from the first tube fitting 31 and reduce the risk of virus spread; during the process of sealing the first tube fitting 31 by the tube plug assembly 41, the swab rod 61 is clamped and the swab cotton tip 62 and the swab rod 61 are respectively sealed in the first tube fitting 31 and the second tube fitting 32 to prevent the virus on the swab cotton tip 62 from contaminating the swab rod 61 and reduce the risk of virus spread.

[0050] In some embodiments of the present application, the clamping member 411 is provided with a guiding portion 412, and the guiding portion 412 is connected to the pipe orifice of the first pipe fitting 31. During the process of the pushing assembly 50 pushing the tube plug assembly 41, the pipe orifice wall of the first pipe fitting 31 presses against the guiding portion 412, so that the clamping members 411 approach each other. After the tube cap assembly 20 is tightened, the clamping members 411 squeeze each other and tightly clamp the swab rod 61, and the clamping members 411 and the pipe orifice of the first pipe fitting 31 squeeze each other.

[0051] During the process of screwing the tube cap assembly 20, the tube cap assembly 20 pushes the pushing assembly 50 to move, and then the pushing assembly 50 pushes the tube plug assembly 41 into the first tube fitting 31. During the process of the tube plug assembly 41 moving into the first tube fitting 31, the pipe orifice wall of the first tube fitting 31 squeezes the guiding portion 412, so that the clamping members 411 approach and squeeze each other. After the tube cap assembly 20 is tightened, the tube plug assembly 41 is pushed into the first tube fitting 31. At this time, the clamping members 411 and the pipe orifice of the first tube fitting 31 squeeze each other, and the clamping members 411 squeeze each other and tightly clamp the swab rod 61. In this way, the pipe orifice of the first tube fitting 31 is sealed by the tube plug assembly 41 and there is no gap at the pipe orifice of the first tube fitting 31, so as to prevent the virus preservation liquid in the first tube fitting 31 from overflowing and ensure the safety of the virus sampling process.

[0052] In some embodiments of the present application, the outer diameter of the first tube fitting 31 is adapted to the inner diameter of the second tube fitting 32.

[0053] By making the outer diameter of the first tube fitting 31 adapted to the inner diameter of the second tube fitting 32, the first tube fitting 31 is prevented from shaking in the second tube fitting 32, and the risk of the virus preservation liquid in the first tube fitting 31 overflowing is further reduced.

[0054] In some embodiments of the present application, the first pipe fitting 31 is provided with a first inner pipe portion 311 and a first outer pipe portion 312. A coolant chamber 313 is provided between the first inner pipe portion 311 and the first outer pipe portion 312. The coolant chamber 313 is filled with coolant, and the first inner pipe portion 311 is used for loading the virus preservation solution.

[0055] By filling the coolant chamber 313 of the first pipe fitting 31 with coolant, the virus preservation solution is thus in a low-temperature state, thereby extending the preservation time of the virus sample and ensuring the activity of the virus sample.

[0056] In some embodiments of the present application, the second pipe fitting 32 is provided with a second inner pipe portion 321 and a second outer pipe portion 322. A cavity 323 is provided between the second inner pipe portion 321 and the second outer pipe portion 322, and the first pipe fitting 31 is disposed within the second inner pipe portion 321.

[0057] By setting the second pipe fitting 32 as a double-layer structure with a cavity 323, the heat exchange between the first pipe fitting 31 and the outside is thus reduced, the temperature of the environment where the first pipe fitting 31 is located is kept stable, and further the temperature of the virus preservation solution within the first pipe fitting 31 is prevented from rising too fast, thereby extending the preservation time of the virus sample and ensuring the activity of the virus sample.

[0058] In some embodiments of the present application, the cavity 323 is in a vacuum state.

[0059] By making the cavity 323 of the second pipe fitting 32 in a vacuum state, the heat exchange between the first pipe fitting 31 and the outside is further reduced, and thus the preservation time of the virus sample is extended more effectively, ensuring the activity of the virus sample.
