Description

Technical Field

[0001] This utility model belongs to the field of embedding box technology and relates to an anti-pollution embedding box. Background Technology

[0002] An embedding cassette is a laboratory accessory primarily used for sample processing in histological and pathological studies. In these fields, the preparation of biological tissues for microscopic observation typically involves steps such as sample fixation, dehydration, clearing, infiltration, and embedding to create sections.

[0003] Existing embedding cassettes, such as the convenient tissue embedding cassette for ESD specimen embedding in pathology disclosed in Chinese patent literature [Patent No.: 202210070079.X; Application Publication No.: CN114383923A], include a cover plate and an embedding cassette body. A latch is provided on one side of the upper end of the cover plate, and an inlay frame is fixedly connected to the middle of the end face of the cover plate facing the embedding cassette body. A locking block is fixedly connected to the middle of the upper end of the cover plate above the inlay frame. A slot is opened in the middle of the upper right end of the embedding cassette body, and a writing panel is provided at the right end of the embedding cassette body. Two rotating shaft blocks are symmetrically fixedly connected to opposite sides of the bottom of the inlay frame, and two connecting shafts are symmetrically fixedly connected to opposite sides of the two rotating shaft blocks. Two connecting grooves are provided on opposite sides of the upper left end of the embedding cassette body to cooperate with the two rotating shaft blocks of the cover plate. Two mounting grooves are symmetrically opened on opposite sides of the inner side walls of the connecting grooves, and a limit connecting seat is fixedly installed in each of the two mounting grooves.

[0004] In this type of embedding cassette, to prevent tissue contamination, the tissue is typically wrapped in filter paper and repeatedly folded before being placed into the cassette for dehydration. Removal requires repeatedly unfolding and retrieving the filter paper, a cumbersome and time-consuming process. Furthermore, wrapping the tissue in paper can cause it to deform due to compression, potentially damaging the tissue. Alternatively, placing the tissue between two flat sheets of filter paper and securing them with a cover plate and the cassette body can lead to problems such as the filter paper edges protruding outside the cassette and the cover plate and cassette body not being securely fastened, causing the tissue to fall out and become contaminated. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an anti-contamination embedding cassette. The technical problem solved is how to prevent tissue from being contaminated and how to prevent tissue from falling out of the embedding cassette.

[0006] The objective of this utility model can be achieved through the following technical solution: a pollution-proof embedding box, comprising a box body and a cover plate hinged to the rear end of the box body, wherein the front end of the box body has an inclined writing board, characterized in that the box body has a holding frame and a paper pressing frame, a paper pressing cavity is provided between the holding frame and the box body, a paper pressing groove is provided between the front end of the holding frame and the writing board, the paper pressing cavity and the paper pressing groove are connected and surround the holding frame, the rear end of the paper pressing frame is hinged to the rear end of the box body, the paper pressing frame can be embedded in the paper pressing cavity and the paper pressing groove, and the front end of the cover plate is fastened to the writing board to cover the holding frame and the paper pressing frame.

[0007] In use, place the first filter paper on the container frame. Push the first filter paper to make it adhere to the inner wall of the container frame. Place the tissue on the first filter paper, then cover it with the second filter paper. Press down the paper holder, which presses the edges of the first and second filter papers into the paper pressing chamber and groove. When the paper holder is embedded in the paper pressing chamber and groove, the first and second filter papers are firmly pressed and positioned, ensuring a high degree of firmness and preventing the first and second filter papers from being exposed. Both the first and second filter papers are flat and enclose the tissue, preventing contamination and damage. Then, fasten the front end of the cover plate onto the writing board, which again presses down the first and second filter papers, preventing the tissue from falling out of the embedding cassette. The embedding cassette containing the tissue can then be removed for dehydration. The writing board is used to write numbers. The paper pressing slot is located between the front of the holding frame and the writing board, so that the paper pressing frame will not block the writing board and it is convenient for the operator to read and write numbers.

[0008] In the aforementioned anti-contamination embedding cassette, the paper presser includes a U-shaped paper press frame located in the center. The paper press frame can be fitted over the holding frame, and the paper press frame and the holding frame are in clearance fit. This structure allows the paper presser to hold down the first and second filter papers without crushing them, preventing tissue contamination and preventing the tissue from falling out of the embedding cassette.

[0009] In the aforementioned anti-contamination embedding cassette, the paper presser includes a pair of hinged rods located at the rear end, which are hinged to the upper part of the rear end of the cassette body. The bottom of the paper pressing groove has a raised support plate. When the paper presser abuts against the support plate, there is a certain distance between the paper presser and the bottom wall of the paper pressing cavity. This structure provides sufficient space below the paper presser to accommodate the circumferential edges of the first and second filter papers, preventing the paper presser from being lifted after pressing down the first and second filter papers. The paper presser has good stability, preventing tissue contamination and preventing the tissue from falling out of the embedding cassette. The certain distance can be 2-5mm.

[0010] In the aforementioned anti-contamination embedding box, the paper holder includes a lever at the front end, and an extension groove is provided between one end of the writing board and the box body. When the paper holder abuts against the support plate, the lever is embedded in the extension groove. The lever is designed for the operator to grip, facilitating the operation of the paper holder and making it easy to open and close. Furthermore, there is only one extension groove and one lever, both located at one end of the writing board, ensuring that the lever does not obstruct the writing of labels on the writing board.

[0011] In the aforementioned anti-contamination embedding box, when the paper presser abuts against the support plate, the front ends of both of the levers are located outside the box body. This structure facilitates the operator in manipulating the paper presser, making its opening and closing convenient.

[0012] In the aforementioned anti-contamination embedding cassette, the rear end of the cover plate has a pair of hinge shafts, and the rear end of the cassette body has a pair of hinge holes. The hinge holes extend upwards through the top of the cassette body, and the openings at the upward-extending points of the hinge holes are constricted. The hinge shafts can pass through the openings and enter the hinge holes, allowing the cover plate and the cassette body to be detachably hinged. With this structure, applying a certain external force can separate the cover plate from the cassette body, allowing the cover plate to be removed when applying wax to the tissue.

[0013] In the above-mentioned anti-pollution embedding box, the writing board has a snap-fit ​​groove at the middle of its top, and the cover plate has a snap-fit ​​connector at the bottom of its front end. The snap-fit ​​connector is embedded in the snap-fit ​​groove to snap-fit ​​and fix the cover plate and the box body together. The cover plate can completely cover the holding frame and the paper presser.

[0014] In the aforementioned anti-contamination embedding cassette, the bottom of the cover plate has a clamping frame. When the cover plate and the cassette body are snapped together, the clamping frame is embedded in the holding frame, and the clamping frame and the holding frame are in clearance fit. The clamping frame can further compress the first and second filter papers. When used in conjunction with the paper presser, it improves the stability of the first and second filter papers after they are pressed, preventing tissue contamination and damage.

[0015] Compared with the prior art, the anti-pollution embedding box provided by this utility model has the following advantages:

[0016] 1. This embedding cassette uses a paper presser to hold down the first and second filter papers, thereby wrapping the tissue between the first and second filter papers. This ensures that the tissue is not contaminated and prevents the tissue from falling out of the embedding cassette. It effectively avoids the problems of mutual compression and deformation caused by the traditional method of wrapping tissue with folded filter paper, and also avoids the problem of reduced dehydration efficiency caused by the stacking of filter paper.

[0017] 2. The paper holder of this embedding cassette maintains a certain distance from the bottom wall of the paper pressing chamber, providing sufficient space for the circumferential edges of the first and second filter papers. After the paper holder presses down on the filter paper, the filter paper will not lift up, thus preventing tissue contamination and preventing the tissue from falling out of the embedding cassette.
