Description

Technical Field

[0001] This utility model relates to laboratory equipment, and in particular to a cell cluster embedding cassette. Background Technology

[0002] Common embedding cassettes include a body and a lid, both of which have through holes. For example, the embedding cassette with Chinese Patent Publication No. CN215179087U includes a body and a positioning tube. A straight tube is integrally formed at the bottom of the body, penetrating the body. The positioning tube passes inside the straight tube, with its outer wall surface fitting against the inner wall surface of the straight tube. The end of the positioning tube facing the positioning tube is closed. Several through holes are formed on the positioning tube, and a biological sample is placed on the positioning tube, fitting against the through holes. After cell clusters dehydrate within the embedding cassette, their volume decreases, and some cell clusters may fall out through the through holes and be lost. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a cell cluster embedding cassette to solve the problem of cell cluster loss.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cell cluster embedding box, including a box body and a box cover, wherein the box body has a first concave cavity, and the bottom of the first concave cavity has a plurality of first through holes; the box cover includes a cover plate and a dam provided on the cover plate, and a second concave cavity is formed in the dam; after the box cover and the box body are fitted together, the dam is inserted into the first concave cavity; the cover plate in the second concave cavity has a plurality of second through holes; a first weighing paper is provided at the bottom of the first concave cavity, and a second weighing paper is provided at the bottom of the second concave cavity; a fixing member for pressing the first weighing paper and the second weighing paper is provided between the box body and the box cover. The principle of this invention is as follows: A first weighing paper is placed in the first concave cavity. The first weighing paper can block the first through hole, but allows the fixative to enter the embedding box. A second weighing paper is placed in the second concave cavity. The second weighing paper can block the second through hole, but allows the fixative to enter the embedding box. The weighing paper can prevent the cell clusters from falling out through the through hole on the embedding box after dehydration and shrinkage, but does not affect the dehydration operation of the cell clusters. The weighing paper is pressed tightly by the fixing component, so that the weighing paper is close to the bottom, ensuring that the weighing paper can block the through hole without affecting the space inside the embedding box.

[0005] As an improvement, the fixing member includes four columns distributed at the four corners of the first cavity. The four columns are arranged in a rectangular shape, and adjacent columns are connected by a connecting rod. The bottom of the column presses against the first weighing paper, and the top of the column presses against the second weighing paper.

[0006] As an improvement, the column and connecting rod are integrally injection molded.

[0007] As an improvement, the upper part of the column is provided with cutting grooves on both sides near the inner wall of the first concave cavity to avoid the dam.

[0008] As an improvement, the bottom of the connecting rod is flush with the bottom of the column.

[0009] As an improvement, one side of the lid is rotatably connected to the box body via a connecting strap, and the other side of the box body is fixedly connected to the box body via a buckle.

[0010] The beneficial effects of this utility model compared with the prior art are:

[0011] Weighing paper prevents cell clusters from falling out through the holes in the embedding cassette after dehydration and shrinkage, without affecting the dehydration process. The weighing paper is pressed tightly against the bottom using a fixing device, ensuring that the weighing paper can block the holes without affecting the space inside the embedding cassette. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the present invention.

[0013] Figure 2 This is an exploded view of the present invention. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 , 2 As shown, a cell embedding cassette includes a body 1 and a lid 2. One side of the lid 2 is rotatably connected to the body 1 via a connecting strap, and the other side of the body 1 is fixedly connected to the body 1 via a snap fastener. The body 1 has a first recess 11, and the bottom of the first recess 11 has a plurality of first through holes 12 arranged in a rectangular array. The lid 2 includes a cover plate 21 and a retaining wall 22 provided on the cover plate 21. A second recess 23 is formed in the retaining wall 22. After the lid 2 and the body 1 are engaged, the retaining wall is inserted into the first recess 11. The cover plate 21 in the second recess 23 has a plurality of second through holes 24 arranged in a rectangular array.

[0016] like Figure 1 , 2 As shown, the first cavity 11 is rectangular, and a first weighing paper 3 is provided at the bottom of the first cavity 11. The size of the first weighing paper 3 is approximately the same as the size of the first cavity 11. After the first weighing paper 3 is laid, it can cover all the first through holes 12. The second cavity 23 is rectangular, and a second weighing paper 4 is provided at the bottom of the second cavity 23. The size of the second weighing paper 4 is approximately the same as the size of the second cavity 23. After the second weighing paper 4 is laid, it can cover all the second through holes 24.

[0017] like Figure 1, 2 As shown, a fixing member 5 for pressing the first weighing paper 3 and the second weighing paper 4 is provided between the box body 1 and the box cover 2. The fixing member 5 includes four pillars 51 distributed at the four corners of the first cavity 11. The four pillars 51 are rectangularly distributed, and adjacent two pillars 51 are connected by a connecting rod 52. The pillars 51 and the connecting rods 52 are integrally injection molded. After the box cover 2 is closed, the bottom of the pillars 51 presses the first weighing paper 3, and the top of the pillars 51 presses the second weighing paper 4. The upper part of the pillars 51 is provided with cutting grooves 53 on both sides near the inner wall of the first cavity 11 to avoid the dam 22. The lower part of the pillars 51 is cylindrical and is attached to the inner walls of both sides of the first cavity 11 for positioning. The fixing member is an integral structure, and it can be positioned by placing it into the first cavity 11. The bottom of the connecting rod 52 is flush with the bottom of the pillars 51, increasing the area for pressing the first weighing paper 3 and making it more flexible.

[0018] The principle of this invention is as follows: A first weighing paper 3 is placed in the first concave cavity 11. The first weighing paper 3 can block the first through hole 12, but allows the fixative to enter the embedding box. A second weighing paper 4 is placed in the second concave cavity 23. The second weighing paper 4 can block the second through hole 24, but allows the fixative to enter the embedding box. The weighing paper can prevent the cell clusters from falling out through the through hole on the embedding box after dehydration and shrinkage, but does not affect the dehydration operation of the cell clusters. The weighing paper is pressed tightly by the fixing component, so that the weighing paper is close to the bottom, ensuring that the weighing paper can block the through hole without affecting the space inside the embedding box.
