Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and more specifically, to a sealing device for tested vacuum blood collection tube samples. Background Technology

[0002] Blood samples are typically stored in pre-tested vacuum blood collection tubes. After collection, these tubes must be sealed to ensure sample integrity and safety. Currently, there are two main sealing methods: one is to seal each tube with an individual rubber stopper. While this method ensures the seal of a single sample, it is inefficient for processing large batches of samples because it only supports individual sealing, making it unsuitable for batch sealing and affecting the speed of the process.

[0003] Another method is to use a single-use plastic cover for batch sealing. This method can seal all blood collection tubes in the storage box at once, greatly improving operational efficiency. However, this method fails to provide direct sealing protection for each individual sample, resulting in poor overall sealing and increasing the risk of sample contamination. Furthermore, during the movement of the storage box, the lack of effective individual sealing measures may lead to blood leakage, posing a biosafety risk. Moreover, when a single sample needs to be extracted, the entire cover must be opened, exposing all samples to the external environment and further increasing the possibility of sample contamination. Utility Model Content

[0004] The present invention aims to provide a sealing device for tested vacuum blood collection tube samples to solve the problem that existing blood collection tube sealing devices cannot simultaneously achieve sealing efficiency and sealing effect.

[0005] This utility model is achieved using the following technical solution:

[0006] This utility model provides a sealing device for tested vacuum blood collection tube samples, including a blood collection tube placement base and a sealing cover plate. The blood collection tube placement base is provided with multiple vertical insertion holes, and each insertion hole is used to insert a blood collection tube.

[0007] The sealing cover plate has multiple through holes, the positions of which correspond to the positions of the insertion holes; each through hole is provided with a sealing plug, one side of which is connected to the sealing cover plate by a flexible connector, and each sealing plug can be inserted into the opening of one of the blood collection tubes to independently seal the blood collection tube.

[0008] As a preferred technical solution:

[0009] Each of the sealing plugs is provided with a lifting component at the top.

[0010] As a preferred technical solution:

[0011] The lifting component uses a pull ring, which is integrated with the sealing plug.

[0012] As a preferred technical solution:

[0013] The lifting component uses a lifting head, which is integrated with the sealing plug.

[0014] As a preferred technical solution:

[0015] A gasket is fitted onto the sealing plug, and the gasket is used to make an interference fit with the inner wall of the blood collection tube.

[0016] As a preferred technical solution:

[0017] A strip is connected to the other side of the sealing plug. One end of the strip is fixedly connected to the sealing plug, and the other end of the strip rests on the upper surface of the sealing cover.

[0018] As a preferred technical solution:

[0019] The size of the through hole is larger than the size of the insertion hole.

[0020] As a preferred technical solution:

[0021] All the aforementioned sockets are arranged in a matrix.

[0022] As a preferred technical solution:

[0023] The sealing plug is made of rubber.

[0024] As a preferred technical solution:

[0025] The flexible connector is made of rubber strip.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0027] 1. The vacuum blood collection tube sample sealing device of this utility model can seal multiple blood collection tubes simultaneously through multiple sealing plugs on the whole plate. By closing the whole plate, batch sealing can be achieved, the sealing efficiency is higher, the operation process can be accelerated, and the operation is simple.

[0028] 2. The vacuum blood collection tube sample sealing device of this utility model has a separate sealing plug (independent sealing structure), which can independently seal each sample, with good sealing performance. Even if it is tilted or even upside down, blood leakage is not likely to occur, thus avoiding biosafety risks.

[0029] 3. The sealing device for tested vacuum blood collection tube samples of this utility model takes into account both sealing efficiency and sealing effect.

[0030] 4. Each sealing plug of the vacuum blood collection tube sample sealing device of this utility model can be opened individually. When extracting a sample, the pull ring on the corresponding sealing plug can be pulled to open the sample to be extracted. Other samples remain sealed, which can avoid spillage of other samples when extracting a single sample, avoid causing biosafety risks, and also avoid contamination of other samples. In addition, the opening operation is simple and the extraction is fast. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Example 1

[0039] like Figures 1-4 As shown, this embodiment proposes a sealing device for tested vacuum blood collection tube samples, including a blood collection tube placement base 1 and a sealing cover plate 2. The blood collection tube placement base 1 is provided with a plurality of vertical insertion holes 101, and a blood collection tube 3 can be inserted into each insertion hole 101.

[0040] The sealing cover plate 2 has multiple through holes 201, the positions of which correspond to the positions of the insertion holes 101. Each through hole 201 contains a sealing plug 6, one side of which is connected to the sealing cover plate 2. Each sealing plug 6 can be inserted into the opening of one of the blood collection tubes 3, independently sealing the blood collection tube 3. In this embodiment, the sealing plug 6 can be a rubber plug.

[0041] Each of the sealing plugs 6 is provided with a lifting component at its top, and the sealing plug 6 can be pulled out of the blood collection tube 3 by lifting the lifting component.

[0042] The lifting component can be a pull ring 5, such as... Figure 5 As shown, this design facilitates the application of force to pull the sealing plug 6 out of the blood collection tube 3. While it's possible to apply force directly to the sealing plug 6 without the pull ring 5, it's not as convenient as using the pull ring 5. The pull ring 5 can be made of plastic, but is not limited to this material.

[0043] However, it is not limited to using a pull ring 5; it can also be achieved by providing a pull head 4 on the sealing plug 6, such as... Figures 1-4 As shown, the sealing plug 6 can be easily lifted. The lifting part of the lifting head 4 can be positioned away from the flexible connector 7 to facilitate the removal and prying off of the sealing plug 6.

[0044] One side of the sealing plug 6 is connected to the sealing cover plate 2 via a flexible connector 7, so that the lifting component can pull the sealing plug 6 out of the blood collection tube 3. The flexible connector 7 can be a rubber band with a certain strength. When no tension is applied to the sealing plug 6, the rubber band can support the sealing plug 6 and keep it horizontal. When tension is applied to the sealing plug 6, the rubber band can bend so as to remove the sealing plug 6 from the blood collection tube 3.

[0045] During the sampling process, the blood collection tubes 3 containing the sample are sequentially inserted into the insertion holes 101 on the blood collection tube placement base 1. After sampling, during the sealing process, the sealing cover plate 2 is placed above all the blood collection tubes 3, and each sealing plug 6 on the sealing cover plate 2 is aligned with each of the blood collection tubes 3. The upper surface of the sealing cover plate 2 is pressed down by hand so that each sealing plug 6 is tightly inserted into each of the blood collection tubes 3, thus sealing all the blood collection tubes 3 at once. Compared with the prior art of using independent rubber plugs to seal each blood collection tube 3, this utility model achieves batch sealing by closing the entire plate, which has higher sealing efficiency and can speed up the operation process.

[0046] Moreover, this invention has an independent sealing structure, which still achieves independent sealing of each sample. The sealing performance is good, and even if it is tilted or placed upside down during movement, blood leakage is not likely to occur in each blood collection tube 3, thus avoiding biosafety risks.

[0047] When separate sampling is required later (such as when a sample needs to be extracted separately for additional testing), simply pull the lifting part on the sealing plug 6 corresponding to the target sample to separate the sealing plug 6 from the blood collection tube 3 and remove the sample from the blood collection tube 3. This allows for separate opening of the plug. During this process, other samples remain sealed. This operation is not only simple and quick to extract via the pull ring 5 or the lifting head 4, enabling rapid sampling, but also does not interfere with or affect surrounding samples, thus avoiding contamination of other samples and the risk of spillage.

[0048] In this embodiment, the blood collection tube placement base 1 is provided with 100 insertion holes 101, all of which are arranged in a 10×10 matrix. The sealing cover plate 2 has 100 through holes 201, all of which are also arranged in a 10×10 matrix. The position of each through hole 201 corresponds to the position of the insertion hole 101. The size of the through hole 201 is larger than the size of the insertion hole 101 because the through hole 201 needs to leave space for the installation of the sealing plug 6 and the flexible connector 7, while the insertion hole 101 only needs to allow the blood collection tube 3 to be inserted. The number and arrangement are not limited to the above; they can be selectively set according to actual needs.

[0049] In this embodiment, the blood collection tube placement base 1 is a foam base, but is not limited to foam material. The sealing cover 2 can be a plastic cover, but is not limited to plastic material.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that:

[0052] To further improve the sealing effect of the sealing plug 6, a silicone annular washer 9 is fitted on each sealing plug 6. The silicone annular washer 9 can be connected to the sealing plug 6 as a whole, or it can be tightly fitted on the sealing plug 6 and will not fall off the sealing plug 6. The silicone annular washer 9 is used to fit tightly with the inner wall of the blood collection tube 3 with an interference fit of 0.5-1mm to ensure good sealing performance.

[0053] Example 3

[0054] The difference between this embodiment and Embodiment 1 is that:

[0055] To prevent the flexible connector 7 from failing to keep the sealing plug 6 horizontal when it is connected to the sealing cover plate 2 on one side, thus affecting subsequent sealing operations and causing inconvenience in aligning the sealing plug 6 with the blood collection tube 3, a support strip 8 is connected to the other side of the sealing plug 6. One end of the support strip 8 is fixedly connected to the sealing plug 6, and the other end of the support strip 8 rests on the upper surface of the sealing cover plate 2. The support strip 8 can be made of rigid plastic, but is not limited to this material.

[0056] The gusset 8 prevents the flexible connector 7 from failing to keep the sealing plug 6 in a horizontal position, while not affecting the use of the lifting component, and the sealing plug 6 can still be pulled out of the blood collection tube 3.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
