AI Technical Summary
例如在制作细胞蜡块前,需要进行离心富集,在离心作用下细胞会在离心管的底部富集,在转移制作细胞蜡块过程中,细胞块结构容易受损,而且由于细胞会残留在离心管的底部或侧壁,导致细胞损失率较高
[0010]As can be seen from the above technical solution, the advantages and positive effects of this novel centrifugal enrichment device for preparing cell blocks are as follows: By placing the embedding paper at the bottom of the centrifuge tube, cells adhere to the embedding paper during centrifugation. When transferring the cell blocks, the embedding paper is directly removed by a lifting thread, reducing cell adhesion to the bottom or sidewall of the centrifuge tube. Simultaneously, the integrity of the cell blocks is better maintained during transfer, reducing cell damage caused by operation. This effectively solves the problems of easily damaged cell block structure and high cell loss rate in traditional processes. The support not only provides stable support for the embedding paper but also ensures its fixed position during centrifugation, thereby improving the centrifugal enrichment effect.

Abstract
Description
Technical Field
[0001] This utility model generally relates to the field of medical technology, and more specifically, to a novel centrifugal enrichment device for preparing cell wax blocks. Background Technology
[0002] Cell paraffin blocks are one of the key techniques in cytopathology for processing liquid specimens, allowing liquid samples to be preserved for a long time, facilitating further pathological molecular biological analysis and subsequent examinations.
[0003] Currently, traditional cell block fabrication processes have some limitations. For example, before fabricating cell blocks, centrifugation is required. During centrifugation, cells tend to accumulate at the bottom of the centrifuge tube. The cell block structure is easily damaged during the transfer process, and because cells may remain at the bottom or sidewall of the centrifuge tube, the cell loss rate is relatively high. Utility Model Content
[0004] This application provides a novel centrifugal enrichment device for preparing cell wax blocks to solve the above-mentioned technical problems.
[0005] This application provides a novel centrifugal enrichment device for preparing cell wax blocks, comprising: a centrifuge tube, embedding paper, a lifting thread, and a support member. The embedding paper is disposed inside the centrifuge tube near the bottom. One end of the lifting thread is connected to the embedding paper, and the other end extends to the opening of the centrifuge tube. The support member is disposed at the bottom of the centrifuge tube and supports the embedding paper.
[0006] According to some embodiments of the present invention, the shape of the embedding paper matches the cross-sectional shape of the centrifuge tube.
[0007] According to some embodiments of the present invention, the lifting lines include four sets, which are respectively connected to the 0°, 90°, 180° and 270° positions of the embedding paper.
[0008] According to some embodiments of the present invention, the support member includes a partition and a frame, wherein a plurality of partitions are arranged in the frame and are interconnected with each other.
[0009] According to some embodiments of the present invention, the top of the support member is a plane, and the bottom of the support member matches the bottom shape of the centrifuge tube.
[0010] As can be seen from the above technical solution, the advantages and positive effects of this novel centrifugal enrichment device for preparing cell blocks are as follows: By placing the embedding paper at the bottom of the centrifuge tube, cells adhere to the embedding paper during centrifugation. When transferring the cell blocks, the embedding paper is directly removed by a lifting thread, reducing cell adhesion to the bottom or sidewall of the centrifuge tube. Simultaneously, the integrity of the cell blocks is better maintained during transfer, reducing cell damage caused by operation. This effectively solves the problems of easily damaged cell block structure and high cell loss rate in traditional processes. The support not only provides stable support for the embedding paper but also ensures its fixed position during centrifugation, thereby improving the centrifugal enrichment effect.

[0024] like Figure 1 As shown in the embodiment, a novel centrifugal enrichment device for preparing cell blocks includes: a centrifuge tube 1, embedding paper 2, a lifting thread 3, and a support 4. The embedding paper 2 is disposed inside the centrifuge tube 1 near the bottom. One end of the lifting thread 3 is connected to the embedding paper 2, and the other end extends to the opening of the centrifuge tube 1. The support 4 is disposed at the bottom of the centrifuge tube 1 and supports the embedding paper 2. By placing the embedding paper 2 at the bottom of the centrifuge tube 1, cells adhere to the embedding paper 2 during centrifugation. When transferring the cell blocks, the embedding paper 2 is directly removed via the lifting thread 3, reducing cell adhesion to the bottom or sidewalls of the centrifuge tube 1. Simultaneously, the integrity of the cell blocks is better maintained during transfer, reducing cell damage caused by operation. This effectively solves the problems of easily damaged cell block structure and high cell loss rate in traditional processes. The support 4 not only provides stable support for the embedding paper 2 but also ensures its fixed position during centrifugation, thereby improving the centrifugation enrichment effect.
[0025] like Figure 2 As shown, in some embodiments of this invention, the shape of the embedding paper 2 matches the cross-sectional shape of the centrifuge tube 1. This matching design ensures that the embedding paper 2 completely covers the bottom area of the centrifuge tube 1, preventing cells from slipping to the edges or sidewalls during centrifugation, thereby improving the uniformity and integrity of cell enrichment. Especially for trace samples, this greatly reduces cell loss during the operation.
[0026] like Figure 2 As shown, in some embodiments of this invention, the lifting threads 3 comprise four sets, respectively connected to the 0°, 90°, 180°, and 270° positions of the embedding paper 2. This symmetrical distribution facilitates the rapid and stable removal of the embedding paper 2 via the lifting threads 3 after centrifugation, reducing cell loss during the operation and ensuring the high efficiency of subsequent cell block preparation.
[0027] like Figure 3 As shown, in some embodiments of this utility model, the support member 4 includes partitions 5 and a frame 6, with multiple partitions 5 intersecting and connecting to each other within the frame 6. The partitions 5 intersect to form a grid structure, which can stably support the embedding paper 2, keeping it flat during centrifugation and preventing wrinkles or displacement due to centrifugal force, thereby ensuring that cells are evenly distributed on the surface of the embedding paper 2.
[0028] like Figure 3As shown, in some embodiments of this utility model, the top of the support member 4 is a flat surface, and the bottom of the support member 4 matches the bottom shape of the centrifuge tube 1. This design allows the support member 4 to be stably placed inside the centrifuge tube 1. The top flat surface provides a flat and reliable support base for the embedding paper 2, ensuring that the embedding paper 2 can fully contact the support surface during centrifugation. At the same time, the close fit between the bottom and the bottom of the centrifuge tube 1 effectively prevents the support member 4 from shifting or shaking inside the tube during centrifugation, ensuring the stable transmission of centrifugal force.
[0029] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
[0030] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any manner.
