Description

Technical Field

[0001] This utility model relates to the field of mouse organ specimen preparation technology, specifically a mouse intestinal roll specimen preparation device. Background Technology

[0002] Pathophysiological verification of intestinal tissue is an indispensable part of medical experimental research. In medical experiments, small animals such as rats, mice, and rabbits are usually used as the subjects for collecting intestinal samples. Specifically, when collecting intestines, intestinal tissue is sampled and the intestine is cut open along its length to form a rectangular intestinal lining. One side of the intestinal lining is the outer wall of the intestine, and the other side is the inner wall of the intestine. The intestinal lining is then soaked in formalin solution for dehydration and preservation. However, the intestinal lining is placed directly in formalin solution in a clump. During the soaking in formalin solution, the intestinal lining will twist, turn, and bend due to dehydration, which greatly increases the difficulty of subsequent smoothing operations.

[0003] In view of the above problems, this utility model is proposed. Utility Model Content

[0025] like Figure 1-3 As shown, a mouse intestinal roll specimen preparation device includes a box body 1, a box cover 2, a sliding plate 3 and an insertion post 4. The top surface of the box body 1 is open, and the box cover 2 is inserted into the top surface of the box body 1. Formalin solution is placed in the box body 1, and the box cover 2 seals the formalin solution after it is closed.

[0026] The sliding plate 3 is located on the inner bottom surface of the box body 1, and the side of the sliding plate 3 is slidably connected to the inner side wall of the box body 1. The sliding direction of the sliding plate 3 is up and down, that is, the sliding plate 3 can move up and down inside the box body 1.

[0027] The upper surface of the sliding plate 3 is symmetrically provided with two rows of insertion holes 33, each row of insertion holes 33 has three holes. The lower end of the insertion post 4 is provided with an insertion block, which is plugged into and connected to the hole 33. The side of the insertion post 4 is provided with multiple rows of horizontal posts 41 at equal intervals from bottom to top, and the horizontal posts 41 are all perpendicular to the insertion post 4.

[0028] The upper surface of the sliding plate 3 is symmetrically provided with two rows of water-permeable holes 32, with three holes in each row. Formalin can easily pass through the water-permeable holes 32, allowing the sliding plate 3 to move smoothly up and down.

[0029] A top handle 21 is provided in the center of the upper surface of the lid 2. The top handle 21 is in the shape of an "n". Two side handles 34 are symmetrically provided on the upper surface of the sliding plate 3. The side handles 34 are in the shape of an "n". The top handle 21 makes it easy to open the lid 2, and the side handles 34 make it easy to remove the sliding plate 3.

[0030] Multiple sliders 31 are symmetrically arranged at equal intervals on the side of the sliding plate 3, and multiple sliding grooves 11 are symmetrically arranged at equal intervals on the inner side of the box body 1. The sliding grooves 11 are parallel to the height direction of the box body 1 and penetrate the upper surface of the box body 1. The sliders 31 are slidably installed in the sliding grooves 11.

[0031] There are two horizontal posts 41 on each side of the insert post 4. The two horizontal posts 41 in each row are symmetrically arranged on the surface of the insert post 4, and the two horizontal posts 41 in each row are staggered vertically.

[0032] The horizontal bars 41 on the left and right insertion posts 4 are distributed in a front-to-back position, while the horizontal bars 41 on the middle horizontal bar 4 are distributed in a left-to-right position. The horizontal bars 41 on the left and right insertion posts 4 and the horizontal bars 41 on the middle insertion post 4 are aligned in the height direction. In this way, the mouse intestine can wrap around the horizontal bars 41 of the insertion post 4 in circles.

[0033] The water-permeable hole 32 is elongated and circular, and the area of ​​the sliding plate 3 is smaller than the area of ​​the inner bottom surface of the box 1.

[0034] In summary: Pour formalin solution into box 1, remove sliding plate 3 and multiple inserts 4 from box 1, wrap mouse intestines around left insert 4, middle insert 4 and right insert 4, and wrap mouse intestines around the horizontal column 41 of left insert 4, middle insert 4 and right insert 4. The horizontal column 41 separates the mouse intestines in the vertical direction to prevent the upper and lower layers of mouse intestines from sticking together.

[0035] Slide the sliding plate 3, multiple inserts 4, and the wrapped mouse intestine into the box 1. The formalin solution can pass smoothly through the water-permeable hole 32. In this way, the mouse intestine is soaked in the formalin solution in the box 1. After soaking for a period of time, wait until the mouse intestine is completely dehydrated, and then completely remove the sliding plate 3, inserts 4, and mouse intestine from the box 1.

[0036] Since the mouse intestine is wrapped in multiple loops 4, there is no natural twisting or bending of the mouse intestine. The mouse intestine only bends at the turning points of the loops 4, so the mouse intestine has a large number of straight segments. This makes it easier to prepare mouse intestine samples later.

[0037] After the mouse intestine is completely dehydrated, the sliding plate 3 and the insert 4 are moved up and completely removed from the formalin solution. The multiple inserts 4 are pulled out from the insertion holes 33. This makes it easier to remove the mouse intestine from the insert 4 for subsequent sample preparation.

[0038] The mouse intestine has a specific shape. After being soaked in formalin solution and dehydrated, the mouse intestine has many straight segments, which facilitates the subsequent processing and preparation of specimen samples.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
