[0021] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0022] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0023] like Figure 1 As shown, a pathological tissue slice bleaching and drying device includes a box body 1, and a cover plate 15 is provided above the front of the box body 1. The sample in the box body 1 can be taken out and placed by opening and closing the cover plate 15. In addition, in a specific embodiment, the opening and closing angle of the cover plate 15 can be set to 90 degrees, so that the cover plate 15 not only has the function of opening and closing, but also can be used as a workbench to facilitate the placement of objects in the experiment. In addition, different grooves can be provided on the cover plate 15 to ensure the stable placement of objects.

[0024] A control device is provided below the box 1, and the operation control of the whole structure can be realized through the control device. A heating layer 13 is provided above the box, and the heating layer 13 can realize the heating inside the box 1. A vent 14 is provided on the top of the box 1, and the vent 14 facilitates the flow of air during the heating process and facilitates the drying of the slide 16. The control device is electrically connected to the heating layer 13, the vent 14, and the rotating bracket 2, and the overall stable operation can be realized through the control device.

[0025] like Figure 2 As shown, a placement plate 3 for fixing a glass slide 16 is provided on a rotating bracket 2 in the box 1, and the rotating bracket 2 is a hexagonal prism structure. During operation, the rotating bracket 2 rotates, and then the glass slide 16 rotates with the placement plate 3, thereby entering the bottom of the box 1, and then rotating from the bottom to the top.

[0026] The bottom of the box 1 is provided with an arc-shaped water storage tank 10. When the upper storage plate 3 of the rotating bracket 2 rotates to the bottom, the sample in the slide 16 contacts with water and is rinsed, and at the same time, the slice is unfolded. The water storage tank 10 has a water inlet 11 above and a drain outlet 12 at its bottom. Water flows in from the water inlet 11 and then is discharged from the drain outlet 12.

[0027] The depth of the water tank 10 is smaller than the diameter of the rotating bracket 2, so that the storage plate 3 enters the water tank 10 at an inclined angle, and then tilts upward to leave the water tank 10. In this process, the curled slices or poorly flattened slices are flattened under the impact of the water flow, and at the same time, the excess paraffin is also washed away. When the slices leave the water surface, the slices are above the slide 16, and as the water flows downward, it is further ensured that the slices are stably spread on the slide 16.

[0028] like Figure 3 As shown, the placement plate 3 is vertically arranged on the connecting rod 4 on the side of the rotating bracket 2, and the connecting rod 4 provides support for the placement plate 3. A limiting groove 5 is provided on the placement plate 3, and the limiting groove 5 realizes the stable placement of the glass slide 16. The depth of the limiting groove 5 is greater than the thickness of the glass slide 16, so that the glass slide 16 is placed in the limiting groove 5, and at the same time, a certain space is formed between the limiting groove 5 to provide a guarantee for the flattening of the slice. A wedge-shaped clamping edge 6 is provided on the outer edge of one side of the limiting groove 5, and the clamping edge 6 ensures the stable fixation of one end of the glass slide 16. A limiting strip 7 is provided on the other side of the limiting groove 5, and the limiting strip 7 realizes the fixation of the other end of the glass slide 16. The material of the limiting strip 7 is rubber, which can achieve stable stretching.

[0029] like Figure 4 As shown, the bottom of the limit groove 5 is provided with a through hole 8 corresponding to the slide 16, and the through hole 8 provides space for the flow of water, which is convenient for the water flow to rinse the slice. An arc groove 9 is provided on one side of the limit groove 5, and the slide can be taken and placed through the groove 9, which is convenient for operation.

[0030] When the device of the present invention is used, first, a slice is placed on the glass slide 16, one side of the slice is aligned with the through hole 8, and the glass slide 16 is placed in the limiting groove 5. At this time, a pocket-like structure is formed between the clamping edge 6 and the limiting groove 5 to fix the glass slide 16. Then the other end of the glass slide 16 is fixed by the limiting strip 7.

[0031] Then, the rotating bracket 2 is operated, driving the slide 16 to immerse in the water tank 10, the slice is flattened under the flushing of the water flow, and the excess paraffin is removed, and then it rises to the top of the box 1. The heating layer 13 is turned on, and at the same time, the vent 14 is operated, and the slice is quickly dried under the heating condition.

[0032] Therefore, the present invention adopts the above-mentioned pathological tissue section rinsing and drying device to realize the automatic completion of section rinsing and drying, and can rinse multiple times, which is convenient and efficient.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
