[0033] The embodiments of this utility model will be described in detail below.

[0034] Example 1

[0035] See Figures 1-4 This embodiment provides a cross-contamination prevention and material separation device, including an operating table 1 that can be movably installed inside a fume hood (not shown in the figure). The operating table 1 includes a tabletop 11 made of stainless steel and legs 12. The tabletop 11 of the operating table 1 has two independent operating areas 13, and each operating area 13 is provided with a specimen retrieval container 2, a waste liquid collection container 3, a specimen bag fixing container 4, a tool container 5, and an embedding cap container 6 at intervals.

[0036] When using the tool, first take out the sampling tool from the tool container 5, then take out the specimen to be sampled from the specimen extraction container 2, and then pour the waste liquid (formaldehyde fixative) remaining in the specimen extraction container 2 into the waste liquid collection container 3. After sampling, put the specimen to be preserved and the fixative into the specimen fixation bag, and then put the specimen fixation bag into the specimen fixation container 4. Take out the embedding box lid from the embedding cap container 6 and cover the specimen after sampling for dehydration preservation. Finally, put the sampling tool back into the tool container 5 for storage.

[0037] As can be seen from the above, various containers are set up on the operating table 1. Arranging these containers in different positions effectively avoids cross-contamination and confusion of specimens, achieves standardized sampling, and significantly improves the accuracy and safety of pathological sampling. It also allows for the standardized use and storage of sampling tools, effectively utilizes the space of the fume hood, and improves work efficiency. Furthermore, since the operating table 1 can be moved inside the fume hood, it facilitates the cleaning of the fume hood and allows for flexible use of the space.

[0038] The purpose of a fume hood is to promptly remove harmful gases such as formaldehyde released by fixative solutions (formaldehyde fixative) to prevent them from affecting the health of the operator.

[0039] Based on the above operating procedure, in order to better suit operating habits and make full use of space, the specimen removal container 2, waste liquid collection container 3, specimen bag fixing container 4, and embedding cap container 6 are arranged sequentially along the length of the table 11, and the tool container 5 and embedding cap container 6 are arranged along the width of the table 11.

[0040] When using, first take out the sampling tool from the tool container 5, and then, according to the operation sequence from right to left, first take out the specimen to be sampled from the specimen extraction container 2, then pour the waste liquid (formaldehyde fixative) in the specimen extraction container 2 into the waste liquid collection container 3. After sampling, put the specimen to be preserved and the fixative into the specimen fixation bag, then put the specimen fixation bag into the specimen fixation container 4, take out the embedding box cap from the embedding cap container 6 and cover the specimen after sampling for dehydration preservation; finally, put the sampling tool back into the tool container 5 for storage.

[0041] The specimen retrieval containers 2 located in the two operating areas 13 are kept far apart from each other, which can keep containers with the same purpose in the two operating areas 13 far apart, further reducing the chance of instrument mixing, specimen cross-contamination or confusion.

[0042] The operating table 1 has multiple storage holes, each used to accommodate a specimen retrieval container 2, a waste liquid collection container 3, a specimen bag fixing container 4, a tool container 5, and an embedding cap container 6. The shape of the storage hole is adapted to the shape of the above containers. For example, the specimen retrieval container 2, waste liquid collection container 3, specimen bag fixing container 4, tool container 5, and embedding cap container 6 are cylindrical, and the storage holes are round holes, with each container inserted into the corresponding storage hole.

[0043] A partition 7 is detachably connected between the two operating areas 13 to enhance physical isolation and help achieve zero confusion. Specifically, the operating table 1 is connected to a connector 8, and one side of the connector 8 has a vertically extending slot 81. One side of the partition 7 is engaged with the connector 8 through this slot 81. In this embodiment, the connector 8 is located on the front side of the operating table 1, the slot 81 is located on the front side of the connector 8, and the partition 7 is mainly used to separate the two operators located on the front side of the operating area 13.

[0044] A right-angle ruler 14 made of stainless steel is installed at the front corner of the operating table 1. The right-angle ruler 14 is used as a measuring tool to measure the size of the specimen during the sampling process, which facilitates standardized sampling and maintains the consistency of the specimen (tissue block) size after sampling.

[0045] The specimen bag fixing container 4, tool container 5, and embedding cap container 6 all have multiple drainage holes to prevent water accumulation inside the containers. The specimen removal container 2 and waste liquid collection container 3 do not have drainage holes.

[0046] Example 2

[0047] See Figures 1-4 This embodiment also includes a stainless steel limiting clip 9, which is used to engage with the lower corner of the partition 7. The limiting clip 9 and the connecting piece 8 are located on opposite sides of the partition 7, and the limiting clip 9 and the connecting piece 8 work together to restrict the movement of the partition 7. The limiting clip 9 is U-shaped and has a thickness of 1mm. A bevel 71 is provided at the lower corner of the partition 7 to facilitate the insertion of the partition 7 into the limiting clip 9. The installation method of the limiting clip 9 and the connecting piece 8 is not limited.

[0048] Example 3

[0049] See Figures 1-4 The difference between this embodiment and embodiment 1 is that the worktable 1 has at least three operating areas 13 on its surface 11.

[0050] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
