Description

Technical Field

[0001] This application relates to the field of sampling tubes, and more particularly to a virus sampling and preservation kit. Background Technology

[0002] Saliva can serve as a mirror of human health, and saliva testing can provide valuable diagnostic information in various environments. Saliva has been used to detect HIV, HBV, and various drugs such as cocaine and alcohol.

[0003] Saliva collection typically involves a collection tube, a preservation tube, and a sampling funnel. The preservation tube contains a preservation solution. During sampling, the sampling funnel is attached to the collection tube. Saliva is spat into the sampling funnel until it reaches the marked line. The preservation solution from the preservation tube is then poured into the collection tube, and the funnel is inverted to mix the saliva thoroughly. The used sampling funnel is then discarded.

[0004] In particular, it is important to avoid the presence of foam in the collected saliva, as this can affect the quality of the saliva collection. During the conventional saliva collection process, it is impossible to effectively filter out the foam in the saliva.

[0005] Therefore, how to design a storage tube kit for saliva foam filtration has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This application provides a virus sampling and preservation kit to at least solve the above-mentioned technical problems existing in the prior art.

[0007] A virus sampling and preservation kit is provided, comprising a tube with openings at both ends;

[0008] Filter funnel; the filter funnel is detachably installed in the inner cavity of the tube body;

[0009] The first tube cap or sampling funnel is installed at one end of the tube body and presses the filtrate funnel tightly into the inner cavity of the tube body;

[0010] The second tube cap is sealed at the other end of the tube body and switches between the first and second states.

[0011] A sealing rod is installed on the second tube cap and extends into the drain port at the bottom of the filter hopper;

[0012] The sealing rod includes a sealing section and a filter section, with the outer diameter of the filter section being smaller than that of the sealing section.

[0013] In the first state, the outer wall of the sealing section abuts against the inner wall of the leak, sealing the leak. In the second state, the sealing section extends to the outside of the leak, and the outer wall of the filter section and the inner wall of the leak form a gap for saliva to pass through.

[0014] In one embodiment, the filtrate hopper includes an overlapping ring, and the inner wall of the tube body is provided with a supporting ring seat. The filtrate hopper is installed in the inner cavity of the tube body, and the bottom wall of the overlapping ring abuts against the top wall of the supporting ring seat.

[0015] In one embodiment, the outer walls at both ends of the pipe body are respectively provided with a first threaded section and a second threaded section, the first pipe cap is threadedly connected to the first threaded section, and the first pipe cap is also provided with a first pressing part extending into the inner cavity of the pipe body and pressing against the overlapping ring.

[0016] In one embodiment, the outer walls at both ends of the tube body are respectively provided with a first threaded section and a second threaded section. The sampling funnel is threadedly connected to the first threaded section. The sampling funnel is provided with a second pressing part extending into the inner cavity of the tube body. The bottom wall of the second pressing part abuts against the top wall of the overlapping ring.

[0017] In one embodiment, the second pipe cap is provided with a plug seat, the sealing rod is plugged into the plug seat, and the second pipe cap is threadedly connected to the second threaded section.

[0018] In one embodiment, the second cap, the inner wall of the tube body, and the outer wall of the filtrate hopper form a storage cavity, which is filled with a storage solution.

[0019] In one embodiment, the sealing section is cylindrical and a sealing ring is installed on the sealing section. In the first state, the sealing ring abuts against the inner wall of the leakage port. The filter section is installed on the sealing section and is conical.

[0020] In one embodiment, the second pipe cap is provided with a drain port and also includes a sealing head; the sealing head is detachably installed on the drain port to seal the drain port.

[0021] In one embodiment, the tube body is provided with a compression part, which is disposed between the first threaded section and the second threaded section to compress the storage cavity.

[0022] In one embodiment, the outer wall of the tube is provided with graduation lines.

[0023] Compared with existing technologies, the virus sampling and preservation kit of this application has the following advantages:

[0024] The first cap encloses the filtrate funnel within the inner cavity of the tube body. In the first state, the sealing section on the second cap extends into the leak and seals the leak, thus sealing the preservation liquid within the chamber formed by the second cap, the filtrate funnel, and the sealing rod. When the first cap is replaced with a sampling funnel, saliva can be spat into the filtrate funnel through the sampling funnel. At this time, a certain amount of foam is present in the saliva. The tube body is placed vertically, and the second cap is adjusted to the second state. At this time, the filtration section and the leak form a gap for the saliva to pass through, thereby filtering the water in the saliva into the preservation liquid and leaving the foam in the filtrate funnel, achieving separation of saliva foam. When the amount of saliva reaches the standard, the second cap is adjusted to the first state and the leak is resealed. Then, the sampling funnel is removed and discarded, and the end of the tube body is sealed with the first cap, thus encapsulating the foam in the filtrate funnel and preventing the saliva foam from being carelessly discarded and causing environmental pollution.

[0043] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] like Figure 1 and Figure 2 As shown, it includes a tube 1 with openings at both ends, wherein the two ends of the tube 1 are interconnected, and the tube 1 can be regarded as a cylindrical structure.

[0045] The tube body 1 has a first cap 3 installed at one end and a second cap 5 installed at the other end. The first cap 3 and the second cap 5 can seal both ends of the tube body 1, thereby allowing the solution to be stored in the inner cavity of the tube body 1.

[0046] It is worth noting here that Figure 1 This refers to the preservation state, specifically the preservation of a preservation solution or a mixture of a preservation solution and saliva. Figure 3 In sampling mode, saliva can be sampled and processed.

[0047] The first tube cap 3 can be replaced with a sampling funnel 4, thereby switching the storage tube from storage state to sampling state, which facilitates saliva sampling.

[0048] Specifically, in order to install the first tube cap 3, the second tube cap 5, and the sampling funnel 4, in this embodiment, as follows: Figure 2As shown, the outer walls of the two ends of the tube body 1 are respectively provided with a first threaded section 11 and a second threaded section 12. The first tube cap 3 and the sampling funnel 4 can be threadedly connected to the tube body 1 through the first threaded section 11, and the second tube cap 5 can be threadedly connected to the tube body 1 through the second threaded section 12.

[0049] It is worth noting that when the second pipe cap 5 is threadedly connected to the pipe body 1, it can switch between a first state and a second state. The first state is as follows: Figure 3 As shown, the second state is as follows Figure 6 As shown.

[0050] During the saliva collection process, foam may appear in the saliva. This foam can affect the quality of the saliva collection. Under normal circumstances, the foam in the collected saliva cannot be filtered out.

[0051] In this embodiment, as Figure 2 and Figure 3 As shown, it also includes a filter funnel 2 installed in the inner cavity of the tube body 1. The filter funnel 2 is funnel-shaped, with a drain outlet 21 at the bottom and an overlapping ring 22 at the outer edge of the top. The inner wall of the tube body 1 is provided with a support ring seat 10. When the filter funnel 2 is installed, the bottom wall of the overlapping ring 22 overlaps with the support ring seat 10 to prevent the filter funnel 2 from falling further downward. To improve the stability of the filter funnel 2, in this embodiment, as shown... Figure 2 and Figure 3 As shown, the first tube cap 3 is also provided with a first pressing part 31 extending into the inner cavity of the tube body 1. When the first tube cap 3 is installed on the tube body 1, the bottom wall of the first pressing part 31 abuts against the top wall of the overlapping ring 22, thereby restricting the upward movement of the filtrate hopper 2 and improving the stability of the filtrate hopper 2 installation.

[0052] In the sampling state, such as Figure 5 and Figure 6 As shown, the sampling funnel 4 includes a second pressing part 41. After the sampling funnel 4 is threadedly connected to the first threaded section 11 of the tube body 1, the second pressing part 41 extends into the inner cavity of the tube body 1. The bottom wall of the second pressing part 41 abuts against the top wall of the overlapping ring 22, thereby restricting the upward movement of the filtrate funnel 2 and improving the stability of the filtrate funnel 2 installation. It is worth noting that, as Figure 7 As shown, the bottom of the second pressing part 41 contracts inward and connects smoothly with the top opening of the filtrate funnel 2. The saliva collected by the sampling funnel 4 can slide down the inner wall of the second pressing part 41 into the sampling funnel 4, ensuring that the saliva is smoothly transferred from the sampling funnel 4 to the tube body 1.

[0053] To enable filtration of collected saliva, in this embodiment, the second tube cap 5 is provided with a vertically upward-extending sealing rod 6. The top of the sealing rod 6 extends through the leakage port 21 into the inner cavity of the filter funnel 2. The sealing rod 6 includes a sealing section 61 and a filtering section 62. In the first state, as shown... Figure 3 As shown, the outer wall of the sealing section 61 abuts against the inner wall of the leakage port 21, thereby sealing the leakage port 21 and preventing saliva from moving downward from the leakage port 21. In the second state, as... Figure 6 As shown, at this time, the filter section 62 is located at the outlet 21. There is a gap between the outer wall of the filter section 62 and the inner wall of the outlet 21. At this time, the water in the saliva in the filter funnel 2 flows down from the gap between the outlet 21 and the filter section 62, leaving the foam in the saliva in the inner cavity of the filter funnel 2.

[0054] In this embodiment, as Figure 3 and Figure 6 As shown, the second cap 5, the inner wall of the tube body 1, and the outer wall of the filter hopper 2 form a storage cavity 13. The storage cavity 13 contains a storage solution. When the storage solution is not in use, the sealing section 61 seals the leakage port 21, sealing the storage solution within the storage cavity 13. When saliva needs to be mixed with the storage solution, such as... Figure 6 As shown, by rotating the second tube cap 5, the sealing rod 6 is moved to the second state. At this time, the saliva filtered in the filter funnel 2 will enter the storage chamber 13 and mix with the storage liquid. When the amount of saliva reaches the specified requirement, the sealing section 61 will re-seal the leak 21, thereby sealing the foam in the saliva in the filter funnel 2.

[0055] In order to observe whether the amount of saliva added meets the standard, in this embodiment, the outer wall of the tube 1 is provided with scale lines 15, wherein the tube 1 is made of transparent material.

[0056] To achieve the installation of the sealing rod 6, in this embodiment, as follows: Figure 3 and Figure 6 As shown, the second pipe cover 5 is provided with a plug seat 51, wherein the sealing rod 6 is plugged into the plug seat 51.

[0057] Specifically, in this embodiment, such as Figure 3 and Figure 6 As shown, the sealing section 61 is cylindrical, and the filter section 62 is installed on top of the sealing section 61 and is conical.

[0058] To further improve the sealing effect of the leak outlet 21, in this embodiment, such as Figure 2 and Figure 3 As shown, the outer wall of the sealing section 61 is provided with a sealing ring 7, wherein the outer wall of the sealing ring 7 abuts against the inner wall of the leakage port 21, thereby strengthening the sealing of the leakage port 21.

[0059] When it is necessary to test the saliva in the storage cavity 13, in order to facilitate the removal of the saliva, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the second tube cap 5 is provided with a drain port 52, and also includes a sealing head 53 that can seal the drain port 52. The sealing head 53 is detachably connected to the second tube cap 5. The sealing head 53 is made of rubber. The tube body 1 is also provided with a squeezing part 14, which is located between the first threaded section 11 and the second threaded section 12 to squeeze the storage cavity 13.

[0060] After the sealing head 53 is removed from the drain port 52, the storage cavity 13 can be easily reduced by squeezing the squeezing part 14. At this time, the mixture of saliva and storage liquid in the storage cavity 13 is squeezed out through the drain port 52, which makes it easier to test the saliva.

[0061] It is worth noting that the extrusion section 14 is made of a flexible material that can be deformed by extrusion, while the first threaded section 11 and the second threaded section 12 of the tube body 1 are made of a hard material to facilitate the installation of the first tube cap 3, the second tube cap 5, and the sampling funnel 4.

[0062] With the above setup, before saliva sampling, the first cap 3 is sealed onto the tube body 1 and fixes the filter funnel 2. At this time, the second cap 5 is in the first state, and the sealing section 61 on the sealing rod 6 blocks the leakage port 21. The preservation solution is stored in the preservation chamber 13. When saliva needs to be collected, the first cap 3 is replaced with a sampling funnel 4. The sampling funnel 4 continues to seal the filter funnel 2 in the inner cavity of the tube body 1. Saliva is spit into the filter funnel 2 using the sampling funnel 4, left to stand for a period of time to allow the foam in the saliva to rise, and then the second cap 5 is rotated to switch the sealing rod 6 to the first state. In the second state, the filter section 62 is located inside the leakage port 21. The outer wall of the filter section 62 and the inner wall of the leakage port 21 have a gap for the saliva to flow down, so that the water in the saliva flows into the storage chamber 13 and mixes with the storage solution. When the mixture reaches the mark 15, the second tube cap 5 can be switched to the first state. At this time, the sealing section 61 re-seals the leakage port 21. The sampling funnel 4 can be removed from the tube body 1 and discarded. The first tube cap 3 is used to seal the tube body 1, so that the foam of saliva is sealed in the filter funnel 2. At this time, the storage tube can be inverted to mix the storage solution and saliva evenly.
