[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figs. 1-3 A rapid pathological slide preparation device includes a box body 1, a top cover 2 at the top of the box body 1, and a lifting device connecting the top cover 2 and the box body 1. The lifting device includes a first fixing plate 3 fixedly connected to the side wall of the top cover 2, and a second fixing plate 6 fixedly connected to the side wall of the box body 1 at the corresponding position. Two hydraulic rods 5 are fixedly connected between the first fixing plate 3 and the second fixing plate 6.

[0020] The top cover 2 has a through groove at its lower end, and a clamping seat 4 is provided in the through groove. The clamping seat 4 clamps a glass slide 12. The clamping seat 4 is composed of a first side plate 11 and a second side plate 14. A card holder is fixedly connected to the side wall of the first side plate 11. An electric telescopic rod 10 is fixedly connected to the inner wall of the through groove at the corresponding position. The extended end of the electric telescopic rod 10 is fixedly connected to the side wall of the card holder. A groove is provided through the side wall of the card holder. A connecting post is fixedly connected to the side wall of the second side plate 14. A spring 13 is elastically connected to the end of the connecting post. The other end of the spring 13 is elastically connected to the bottom of the groove. A nozzle 9 is fixedly connected to the inner wall of the first side plate 11. A water inlet pipe 8 is fixedly connected to the nozzle 9. Slots are provided through the opposite side walls of the first side plate 11 and the second side plate 14. The glass slide 12 is clamped in the two slots.

[0021] The housing 1 contains a rotating disk 15, and a liquid storage device is installed through the side wall of the rotating disk 15. The liquid storage device includes multiple fixed slots installed through the side wall of the rotating disk 15, and a liquid storage bottle 16 is fitted in each of the multiple fixed slots. The positions of the multiple liquid storage bottles 16 correspond vertically to the positions of the clamping seats 4. The number of liquid storage bottles 16 is multiple, not just three. The specific number can be determined according to the actual use. A cleaning device is installed through the side wall of the rotating disk 15. The cleaning device includes an opening 17 installed through the side wall of the rotating disk 15. A drain pipe 7 is fixedly connected through the side wall of the housing 1 at the corresponding position. A motor 18 is fixedly connected to the bottom of the housing 1 at the corresponding position. The output shaft of the motor 18 is fixedly connected to the rotating disk 15.

[0022] Specifically, the clamping seat 4 can be fully inserted into the through groove.

[0023] In this utility model, the operator can add hematoxylin dye, hydrochloric acid ethanol solution, weak alkaline solution, eosin dye, etc. to each of the storage bottles 16 respectively. The second side plate 14 on one side is pulled to insert the glass slide 12 into the two slots. Then, the top cover 2 is driven down by the two hydraulic rods 5, so that the clamping seat 4 enters the box 1.

[0024] First, the clamping seat 4, carrying the glass slide 12, is immersed in the hematoxylin staining solution for several minutes, causing the chromatin in the cell nucleus and the nucleic acid in the cytoplasm to turn purple-blue. Then, the electric telescopic rod 10 moves the glass slide 12 back into the channel. Next, the motor 18 drives the rotating disk 15 to rotate to the opening 17, and the glass slide 12 falls back down. The water inlet pipe 8 is controlled by the relevant control equipment in the prior art to spray cleaning water through the nozzle 9 to wash away the residual staining solution. Then, the glass slide 12 is raised, and the rotating disk 15 rotates to the hydrochloric acid ethanol solution position. Place the slide 12 in a solution and immerse it in the solution. The cytoplasm and connective tissue will be destained by the hydrochloric acid-ethanol differentiation, leaving only the nucleus stained. Repeat the above operation, rinsing off the excess solution with clean water and then immersing the slide 12 in a weakly alkaline solution to turn it blue again, making the cell nucleus blue. Repeat the above water rinsing operation to remove the excess solution and then immerse the slide 12 in the corresponding eosin staining solution to stain the components in the cytoplasm and extracellular matrix red. Then remove the slide 12 and proceed to the next step.

[0025] 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.
