Description
Technical Field
[0001] The utility model relates to the technical field of biological science, and particularly relates to a dewaxing device for paraffin sections. Background Art
[0002] Paraffin sectioning is a basic experimental method in biology. Paraffin sections are not only used to observe the morphological structure of cell tissues, but also can be used to measure the content of DNA / RNA and protein expression, and are widely used in pathology and tumor detection. Therefore, how to quickly and efficiently obtain nucleic acids in paraffin sections has become particularly important. Making paraffin sections includes steps such as material sampling, fixation, washing and dehydration, clearing, wax infiltration, embedding, sectioning and pasting, dewaxing, staining, dehydration, clearing, and coverslipping. Among them, the dewaxing process requires immersing paraffin sections in multiple groups of xylene with different concentrations and ethanol with different concentrations for a certain period of time.
[0003] In an existing dewaxing device for paraffin sections, when immersed in the xylene solution, the xylene solution volatilizes into the air and enters the body of the staff through the respiratory tract, skin, and digestive tract, resulting in depression of the human central nervous system, symptoms such as dizziness, nausea, fatigue, and eye and nose irritation. In severe cases, it can cause confusion or even coma, and usually only one section can be dewaxed at a time, with low dewaxing efficiency. Therefore, a dewaxing device for paraffin sections is proposed to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0027] In the embodiment, given by Figures 1-5 a dewaxing device for paraffin sections, the present utility model includes a processing box 1 and a loading frame 2. A filter box 3 is fixedly connected to the outside of the processing box 1, an activated carbon box 4 is assembled inside the filter box 3, an air pump 5 is fixedly connected to the inside of the processing box 1 in front of the activated carbon box 4, a connecting pipe 6 extending to the inside of the processing box 1 is fixedly connected to the outside of the air outlet of the air pump 5, a fan 7 is fixedly connected to the inside of the processing box 1 behind the connecting pipe 6, a placing plate 8 is fixedly connected to the inner wall of the loading frame 2, a placing groove is opened inside the placing plate 8, and a lid 9 is snap-fitted to the top of the loading frame 2.
[0028] It should be noted that, referring to Figure 5 , the engaging structure of the lid 9 includes an engaging rod rotatably connected to the outside of the lid 9, and an engaging seat is fixedly connected to the outside of the loading frame 2. The outer shape of the engaging seat is C-shaped. When the engaging rod rotates into the inside of the engaging seat, the bottom of the engaging rod will abut against the engaging seat, resulting in the inability to remove the lid 9.
[0029] First, place the paraffin section inside the placement groove of the placement plate 8, cover the lid 9 for immersion dewaxing. The liquid for immersion volatilizes into the air, and the harmful gas needs to be treated. Start the air pump 5. The air pump 5 sucks the gas inside the processing box 1 into the inside of the filtering box 3, absorbs it through the activated carbon box 4, and then enters the connecting pipe 6 after treatment. Start the fan 7, and the treated air is blown into the inside of the processing box 1 by the fan 7 through the connecting pipe 6.
[0030] Specifically, referring to Figure 2 and Figure 3 , a strip-shaped hole is provided inside the loading frame 2, and a sliding column 10 is slidably connected inside the lid 9. A spring 11 is fixedly connected to the outside of the sliding column 10, and a lower pressing plate 12 is fixedly connected to the bottom of the sliding column 10.
[0031] In this embodiment, after the paraffin section is placed inside the loading frame 2, cover the lid 9. The lower pressing plate 12 fixes the paraffin section, the spring 11 is compressed, and the lower pressing plate 12 drives the sliding column 10 to slide upward, so that the paraffin section will not shake during immersion dewaxing.
[0032] Specifically, referring to Figure 3 and Figure 4 , a filter plate 13 located behind the activated carbon box 4 is fixedly connected inside the filtering box 3, and a connecting column 14 is slidably connected inside the filtering box 3. A scraping plate 15 that abuts against the filter plate 13 is fixedly connected to the left side of the connecting column 14.
[0033] In this embodiment, the filter plate 13 filters dust and impurities in the air. When there is more dust on the outside of the filter plate 13 and it clogs the filter plate 13, pull the connecting column 14 to the right. The connecting column 14 drives the scraping plate 15 to slide to the right, and the scraping plate 15 scrapes off the dust on the outside of the filter plate 13.
[0034] Specifically, referring to Figure 1 , a dust discharge frame 16 is fixedly connected to the bottom of the filtering box 3, and a fixed cover 17 is assembled at the bottom of the dust discharge frame 16.
[0035] In this embodiment, the dust scraped off by the scraping plate 15 falls into the inside of the dust discharge frame 16, and the dust inside the dust discharge frame 16 is taken out by removing the fixed cover 17.
[0036] Specifically, referring to Figure 2 and Figure 3, a lead screw slide rail 18 is installed inside the processing box 1. A bottom of a slider of the lead screw slide rail 18 is fixedly connected to an electric push rod 19. An output end of the electric push rod 19 is fixedly connected to a fixing plate 20, and the fixing plate 20 is fixedly connected to the loading frame 2.
[0037] In this embodiment, the electric push rod 19 is driven to slide by the lead screw slide rail 18, so that the loading frame 2 slides under the electric push rod 19 through the fixing plate 20, so that paraffin sections can be placed in different liquids for immersion dewaxing. When the electric push rod 19 retracts, the loading frame 2 moves upward to be separated from the immersion in the immersion box 21. When the electric push rod 19 extends outward, the loading frame 2 moves downward to approach the immersion box 21 and be immersed therein.
[0038] Specifically, referring to Figure 2 , an inner bottom wall of the processing box 1 is fixedly connected to an immersion box 21, and a rear side of the processing box 1 is fixedly connected to a controller 22.
[0039] In this embodiment, by replacing different immersion boxes 21, the loading frame 2 can slide through the lead screw slide rail 18 into different immersion boxes 21 for immersion. The controller 22 controls the downward immersion of the loading frame 2, the transfer of different immersion boxes 21, and the treatment of harmful gases inside the processing box 1.
[0040] Working principle:
[0041] First: First, place the paraffin section inside the placement groove of the placement plate 8, cover the box cover 9, drive the electric push rod 19 to slide through the lead screw slide rail 18, so that the loading frame 2 slides under the electric push rod 19 through the fixing plate 20, so that the paraffin section can be placed in different immersion boxes 21 for immersion dewaxing. The liquid for immersion volatilizes into the air, and the harmful gas needs to be treated;
[0042] Then: Start the air pump 5. The air pump 5 sucks the harmful gas inside the processing box 1 into the inside of the filter box 3, absorbs it through the activated carbon box 4, and the filter plate 13 filters the dust and impurities in the air. When there is more dust on the outside of the filter plate 13 and it blocks the filter plate 13, pull the connecting column 14 to the right. The connecting column 14 drives the scraper 15 to slide to the right, and the scraper 15 scrapes off the dust on the outside of the filter plate 13. After treatment, it enters the connecting pipe 6. Start the fan 7, and the treated air is blown into the inside of the processing box 1 by the fan 7 through the connecting pipe 6.
