Description

Technical Field

[0001] The utility model relates to the technical field of tissue cell staining, and more specifically, it relates to a dehydration box. Background Art

[0002] Tissue dehydration is a very important part of pathological section preparation. This process indirectly affects the subsequent staining results and the accuracy of experimental observation. The actual operation of tissue dehydration is to perform pre-treatment for embedding. By using the processes of dehydration and embedding, the water in the tissue is replaced with paraffin, which is convenient for section preparation and long-term preservation.

[0003] In the prior art, after dehydration is performed in most dehydration boxes, the pathological tissue needs to be taken out of the dehydration box and re-placed in an embedding box for embedding operations, resulting in an unsmooth connection of the entire process and overly cumbersome operations. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present utility model is to provide a dehydration box that can establish a connection between the dehydration process and the embedding process, and on the premise of realizing the dehydration process operation, achieve the basis for implementing the embedding process, so as to simplify the process and operation.

The bottom box and the frame are respectively provided with a first grid groove and a second grid groove on the side close to each other. The frame is provided with a channel for injecting a dehydrating solution. A through-hole for embedding the frame is opened in the top cover. The frame gradually moves within the through-hole to form a receiving space for placing and dehydrating pathological tissues or cell clusters.

[0006] Preferably, a contact edge is provided on the inner side of the bottom box, and the contact edge is circumferentially arranged around the grid groove. A groove is provided on the inner side of the top cover, and the groove is circumferentially arranged around the through-hole. When the top cover is snap-fitted to the bottom box, the contact edge is inserted into the groove to form a side seal within the receiving space.

[0007] Preferably, a contact post and a blind hole are respectively provided on the bottom box and the top cover on the side close to each other. The contact post can be inserted into the blind hole to form a pre-connection and fixation.

[0008] Preferably, both ends of the frame at the channel are respectively provided in a funnel shape, and a cut surface is provided at the connection of the inner side of the frame at the end of the channel.

[0009] Preferably, a plurality of pulling handrails are provided on the frame.

[0010] In summary, the beneficial effects of the present utility model are as follows:

[0011] 1. When entering the dehydration stage, first place the pathological tissue or cell mass on the first grid slot, and the top cover is buckled on the bottom box.

[0021] A dehydration box, see Figures 1 to 3 , including a bottom box 1, a top cover 11 buckled with the bottom box 1, and a frame 12 embedded in the top cover 11. The bottom box 1 and the frame 12 are respectively provided with a first grid groove 13 and a second grid groove 21 on the side close to each other. A channel 14 for injecting dehydration liquid is provided on the frame 12. A through diameter 15 for embedding the frame 12 is opened in the top cover 11. The frame 12 gradually moves within the through diameter 15 and forms a receiving space for placing and dehydrating pathological tissues or cell masses.

[0022] During specific implementation, when entering the dehydration stage, first place the pathological tissue or cell mass on the first grid groove 13, buckle the top cover 11 on the bottom box 1. The first grid groove 13, the second grid groove 21, and the through diameter 15 form a receiving space for placing the pathological tissue or cell mass. Both the first grid groove 13 and the second grid groove 21 are in an open state. The frame 12 slides along the through diameter 15 and is embedded on the top cover 11, and then it is immersed in the dehydration liquid. The dehydration liquid is respectively poured in through the first grid groove 13 and the second grid groove 21 to complete the dehydration process.

[0023] When entering the embedding stage, by blocking the notch of the first grid groove 13, liquid paraffin is injected through the through diameter 15, and the pathological tissue or cell mass is wrapped and solidified within the receiving space. While injecting paraffin under high pressure, the frame 12 slides and ascends within the through diameter 15 along with the extrusion of the paraffin, causing a certain extrusion on the pathological tissue or cell mass within the receiving space, prompting the pathological tissue or cell mass to be evenly laid at the bottom of the receiving space. After the wax block reaches the preset wax block thickness, wait for the paraffin to cool and solidify, then disassemble the bottom box 1, the top cover 11, and the frame 12 to complete dewaxing, realizing the dual use of one object, simplifying the design structure, and optimizing the process operation.

[0024] Moreover, through the design of the box body 12 and the through diameter 15, a connection is established between the dehydration process and the embedding process, enabling the two processes to be quickly implemented one after another. On the premise of realizing the operation of the dehydration process, a foundation for implementing the embedding process is constructed.

[0025] Specifically, an abutting edge 16 is provided inside the bottom box 1, and the abutting edge 16 is arranged circumferentially around the grille groove. A groove 17 is provided inside the top cover 11, and the groove 17 is arranged circumferentially around the through diameter 15. When the top cover 11 is buckled on the bottom box 1, the abutting edge 16 is inserted into the groove 17 to form a side seal within the accommodation space.

[0026] Due to the high-pressure injection of paraffin, it is easy to overflow. When the top cover 11 is buckled on the bottom box 1, the abutting edge 16 is inserted into the groove 17 to form a side seal within the accommodation space, preventing the paraffin from overflowing from the accommodation space and avoiding waste of paraffin.

[0027] During dehydration, the dehydrating liquid flows into the accommodation space through the first grille groove 13, the second grille groove 21, and the through diameter 15. The abutting edge 16 is inserted into the groove 17 to form a side seal within the accommodation space, which facilitates the full immersion of pathological tissues or cell clusters by the dehydrating liquid.

[0028] Specifically, the bottom box 1 and the top cover 11 are respectively provided with an abutting post 18 and a blind hole 19 on the side close to each other. The abutting post 18 can be inserted into the blind hole 19 to form a pre-connection and fixation.

[0029] To improve the matching efficiency between the abutting edge 16 and the groove 17, the abutting post 18 is inserted into the blind hole 19 to form a pre-connection and fixation, and then the abutting edge 16 is inserted into the groove 17 to form a side seal of the accommodation space.

[0030] Specifically, the box body 12 is respectively arranged in a funnel shape at both ends of the channel 14, and a cut surface 2 is arranged at the connection of the inner side of the box body 12 at the end of the channel 14.

[0031] The funnel-shaped setting on the outside of the channel 14 helps the dehydrating liquid to be slowly injected into the accommodation space under the high-pressure injection of the dehydrating liquid, effectively increasing the pressure of the injected dehydrating liquid.

[0032] At the same time, the funnel-shaped setting on the inside of the channel 14, combined with the cut surface 2 arranged at the connection of the inner side of the box body 12 at the end of the channel 14, enables the dehydrating liquid to diffuse around the accommodation space relying on the funnel-shaped edge and the cut surface 2 when the dehydrating liquid enters the accommodation space, avoiding the accumulation of the dehydrating liquid around the channel 14.

[0033] Specifically, a plurality of pulling handrails 3 are provided on the housing 12.

[0034] The pulling handrail 3 of this embodiment provides a force application point for tensile stretching of the movement of the housing 12 within the through diameter 15.

[0035] The above embodiments are merely explanations of the present invention, and they are not limitations to the present invention. After reading this specification, those skilled in the art can make modifications to the embodiments without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
