Description

Technical Field

[0001] This invention relates to the field of sampling tube technology, specifically to a spill-proof sample collection container and its usage method. Background Technology

[0002] Sample collection, often simply called sampling, is a method of obtaining samples and a scientific research technique. In the medical field, sampling is also a common technique for pathological examination. The collected sample solution is usually placed in a sampling tube and then transported to the laboratory for testing. Current sampling tubes typically consist of a tube body and a cap, with the cap locking into the tube body for sealing. While this structure facilitates sampling, gaps exist at the locking point between the cap and the tube body. When the tube body is shaken, a small amount of sample solution may leak out from the locking point, potentially causing biosafety issues. Therefore, a sampling tube that is both easy to use and has a better seal is urgently needed. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the sample solution is easily leaked at the seal when the collection tube is shaken in the prior art, thereby providing a spill-proof sample collection container and its usage method.

[0004] To address the above problems, the present invention provides a spill-proof sample collection container, comprising:

[0005] Cover;

[0006] The container body has a liquid-containing cavity inside, and the opening end of the liquid-containing cavity is detachably connected to the cover.

[0007] An isolation gasket is glued to the opening of the liquid-containing cavity and located within the cover body; the isolation gasket has an glued state before sampling and a removed state during sampling.

[0008] A sealing sheet is disposed within the cover body and is adapted to be located on the side of the isolation gasket opposite to the liquid-containing cavity when the isolation gasket is in the adhesive state, and adapted to be adhesive to the opening of the liquid-containing cavity when the isolation gasket is in the removable state.

[0009] Optionally, the sealing sheet is made of an elastic material and has cuts on it suitable for a sampling tool to pass through.

[0010] Optionally, the cut is a cross-shaped cut.

[0011] Optionally, the thickness of the sealing sheet is 0.5 mm to 1 mm.

[0012] Optionally, the sealing sheet is made of a hydrophobic material.

[0013] Optionally, the isolation pad includes:

[0014] The gasket body is connected to the opening of the liquid-containing cavity;

[0015] A tear strip is attached to the gasket body and protrudes from the outer periphery of the gasket body.

[0016] Optionally, the gasket body is annular.

[0017] Optionally, the gasket body is sheet-shaped.

[0018] Optionally, the cover is threadedly connected to the container body.

[0019] A method of use, applied to a spill-proof sample collection container as described above, includes the following steps:

[0020] Disassemble and separate the cover, the container body, and the sealing sheet;

[0021] Remove the isolation pad;

[0022] sampling;

[0023] The sealing sheet and the cover are sequentially installed on the container body.

[0024] The present invention has the following advantages:

[0025] 1. The spill-proof sample collection container provided by the present invention includes a lid, a container body, an isolation gasket, and a sealing sheet. The container body has a liquid-containing cavity, the opening of which is detachably connected to the lid. The isolation gasket is glued to the opening of the liquid-containing cavity and located within the lid. The isolation gasket has an glued state before sampling and a removed state during sampling. The sealing sheet is disposed within the lid and is adapted to be located on the side of the isolation gasket opposite to the liquid-containing cavity when the isolation gasket is in the glued state, and adapted to be glued to the opening of the liquid-containing cavity when the isolation gasket is in the removed state.

[0026] By sealing the opening of the liquid-containing chamber with an adhesive sealing strip, it is possible to prevent the sample solution from overflowing from the opening and spilling out from the connection between the cap and the container body when the collection tube is shaken, thus avoiding cross-contamination and biosafety risks caused by accidental spillage, splashing, and evaporation of the sample solution during laboratory testing. Simultaneously, the open opening of the liquid-containing chamber facilitates sampling. Therefore, an isolation gasket is first adhesive-bonded to the opening of the liquid-containing chamber to prevent the sealing strip from being fixed to the opening before sampling. During sampling, the cap and sealing strip can be removed first, and then the adhesive isolation gasket can be peeled off to obtain the open opening of the liquid-containing chamber. Sampling can then be performed. After sampling, the sealing strip can be placed directly at the opening of the liquid-containing chamber, where the adhesive sealant further secures the sealing strip. Finally, the cap is replaced to provide a second seal to the container body.

[0027] The sealing strip in this device achieves a better sealing effect, preventing sample solution from leaking from the seal when the device is shaken, and also preventing the sample solution in the liquid-containing chamber from evaporating; at the same time, the isolation gasket ensures that the opening of the liquid-containing chamber is completely open during sampling. Therefore, this device not only has good sealing performance but also facilitates sampling.

[0028] 2. The spill-proof sample collection container provided by the present invention has a sealing sheet made of elastic material. The sealing sheet has a cut suitable for the sampling tool to pass through. During sampling, the test tube can be directly inserted into the container body. The cut on the elastic sealing sheet undergoes elastic deformation to facilitate the passage of the sampling tool. When the sampling tool is removed, the edge of the cut on the elastic sealing sheet can retain the sample solution carried on the surface of the sampling tool. At the same time, the cut is small and there is almost no leakage of sample solution at the cut, ensuring the sealing performance of the device.

[0029] 3. The spill-proof sample collection container provided by the present invention includes an isolation pad comprising a pad body and a tear strip. The pad body is connected to the opening of the liquid-containing cavity; the tear strip is connected to the pad body and protrudes from the outer periphery of the pad body.

[0030] The isolation gasket can be easily removed by tearing the tear strip on the gasket body by hand, without the need for other tools, saving operation time. It also has a simple structure and low manufacturing cost.

[0031] 4. The spill-proof sample collection container provided by the present invention has a lid that is threadedly connected to the container body. Compared with snap-fit, the threaded connection has better sealing performance. Attached Figure Description

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] This embodiment provides a spill-proof sample collection container, such as... Figure 1 As shown, the container includes a cover 1, a container body 2, an isolation gasket 3, and a sealing sheet 4. The container body 2 has a liquid-containing cavity 21, the opening of which is detachably connected to the cover 1. The isolation gasket 3 is glued to the opening of the liquid-containing cavity 21 and is located within the cover 1. The isolation gasket 3 has an glued state before sampling and a removable state during sampling. The isolation gasket 3 can be made of an anti-stick material for easy removal. The sealing sheet 4 is disposed within the cover 1, adapted to be located on the side of the isolation gasket 3 opposite to the liquid-containing cavity 21 when the isolation gasket 3 is in the glued state, and adapted to be glued to the opening of the liquid-containing cavity 21 when the isolation gasket 3 is in the removable state. The materials of the cover 1 and the container body 2 are not further limited here; for example, they can be plastic.

[0043] By sealing the liquid-containing cavity 21 with the sealing sheet 4 glued at the opening of the liquid-containing cavity 21, the sample solution is prevented from overflowing from the opening of the liquid-containing cavity 21 and from spilling out from the connection between the cover 1 and the container body 2 when the collection tube is shaken, thus preventing sample solution leakage. This also avoids cross-contamination and biosafety risks caused by accidental spillage, splashing and volatilization of sample solution during laboratory testing. Meanwhile, the open opening of the liquid-containing cavity 21 facilitates sampling. Therefore, the isolation gasket 3 is first glued to the opening of the liquid-containing cavity 21 to prevent the sealing sheet 4 from being fixed to the opening of the liquid-containing cavity 21 before sampling. Then, during sampling, the cover 1 and the sealing sheet 4 can be disassembled first, and then the glued isolation gasket 3 can be torn off to obtain the open opening of the liquid-containing cavity 21. Sampling can then be performed. After sampling is completed, the sealing sheet 4 can be placed directly at the opening of the liquid-containing cavity 21. The adhesive at the opening will stick the sealing sheet 4 to the opening, thereby fixing the sealing sheet 4. Finally, the cover 1 is put on to seal the container body 2 for the second time.

[0044] The sealing sheet 4 in this device achieves a better sealing effect, preventing sample solution from leaking from the seal when the device is shaken, and also preventing the sample solution in the liquid-containing chamber 21 from evaporating; at the same time, the isolation pad 3 ensures that the opening of the liquid-containing chamber 21 is completely open when sampling. Therefore, this device not only has good sealing performance but also facilitates sampling.

[0045] Optionally, a sealing adhesive may be provided at the opening of the liquid-containing cavity 21 to achieve bonding of the isolation gasket 3 or the sealing sheet 4. The sealing adhesive may be a waterproof, weather-resistant, inert adhesive.

[0046] Optionally, the sealing sheet 4 is made of an elastic material, such as silicone. The sealing sheet 4 has a slit suitable for a sampling tool to pass through. During sampling, the test tube can be directly inserted into the container body. The elastic deformation of the slit on the sealing sheet facilitates the passage of the sampling tool. When the sampling tool is removed, the edge of the slit on the elastic sealing sheet can trap sample solution carried on the surface of the sampling tool. Simultaneously, the slit is small, and there is almost no leakage of sample solution at the slit, ensuring the sealing of the device. Specifically, the sampling tool can be a sampling tube.

[0047] Optionally, the cut 5 is a cross-shaped cut, which makes sampling more convenient while ensuring the sealing of the device. As an alternative implementation, the cut 5 can also be snowflake-shaped, as long as it meets the requirements of convenient sampling and sealing effect.

[0048] Optionally, the thickness of the sealing sheet 4 is 0.5 mm to 1 mm. Specifically, it can be 0.5 mm, 0.8 mm, or 1 mm.

[0049] Optionally, the sealing sheet 4 is made of a hydrophobic material to prevent the sealing sheet 4 from being wetted or corroded by the sample solution.

[0050] Optionally, the isolation gasket 3 includes a gasket body and a tear strip. The gasket body is connected to the opening of the liquid-containing cavity 21; the tear strip is connected to the gasket body and protrudes from the outer periphery of the gasket body. Specifically, the isolation gasket 3 can be made of aluminum foil.

[0051] The isolation pad 3 can be removed by tearing the tear strip on the pad body by hand, which makes it convenient to remove the isolation pad 3 without the need for other tools, saving operation time. It also has a simple structure and low manufacturing cost.

[0052] Optionally, the gasket body is annular and can cover the sealing adhesive at the opening of the liquid-containing cavity 21. The annular gasket body uses less material, saving manufacturing costs.

[0053] Optionally, the cover 1 is threadedly connected to the container body 2. Compared with snap-fit, the threaded connection has better sealing performance.

[0054] Optionally, the bottom of the liquid-containing cavity 21 can be designed as an inverted cone, so that the bottom of the liquid-containing cavity 21 matches the sampling head of the sampling tool, making it easier for the sampling tool to remove all the sample solution in the liquid-containing cavity 21.

[0055] A method of use, applied to the spill-proof sample collection container as described above, includes the following steps: disassembling and separating the cover 1, the container body 2, and the sealing sheet 4; removing the isolation gasket 3; sampling; and sequentially installing the sealing sheet 4 and the cover 1 onto the container body 2. Since different sampling methods exist for different samples, the sampling steps are not further limited here. Specifically, sampling in this document refers to obtaining a sample and placing it within the liquid-containing cavity 21.

[0056] Example 2

[0057] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the gasket body is sheet-shaped, which is sufficient to cover the sealing adhesive at the opening of the liquid-containing cavity 21. The sheet-shaped gasket body can provide a better sealing effect on the container body 2 before use, preventing the liquid-containing cavity 21 from being contaminated.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
