Description

Technical Field

[0001] The utility model relates to the technical field of biological experimental equipment, in particular to a HE staining slide device. Background Art

[0002] HE stained slides refer to slides made after conventional histological staining, which are usually used for tissue section observation and analysis in the fields of medicine and biology. HE refers to the abbreviation of the two dyes hematoxylin and eosin.

[0003] HE staining is a commonly used staining method used to highlight the morphology and structure of the cell nucleus and cytoplasm in tissue sections. Hemoglobin staining will stain the cell nucleus blue or purple, while acetohematin staining will stain the cytoplasm pink. Through HE staining, different types of cells, tissue structures, and the staining properties of the cell nucleus can be clearly observed and distinguished.

[0004] For example, the utility model with application number 201720452436.3 discloses a microorganism-stained slide, which can more clearly observe the state and structure of the microorganisms through the anti-reflection film, and can also measure the diameter of the microorganisms through the ruler in the groove, making the observation results more accurate and the research more thorough.

[0005] Similar to the above application, there are still some shortcomings:

[0006] This type of microorganism-stained slide is provided with a groove for placing the sample for detection. Although it is conducive to the stability of sample placement, there is a right angle inside the groove. Although it is conducive to the stability of the sample, it is not conducive to cleaning the slide after the sample is tested. The cleaning time of the slide needs to be increased, otherwise the sample is very likely to remain in the groove, affecting the experimental detection.

[0007] Therefore, a HE staining slide device was designed to optimize the above problems. Utility Model Content

[0008] The main purpose of the utility model is to provide a HE staining slide device to solve the related technical problems raised in the above background technology.

[0009] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0010] A HE staining glass slide device comprises a taking area, a substrate is fixed on one side of the taking area, a scale line is arranged at the middle position of the top of the substrate, a glass slide is fixed on the top of the substrate, a fixing plate is fixed on the top of the glass slide, and a curved groove is arranged on the top of the fixing plate.

[0011] Preferably, a contrast area is provided on the top of one end of the slide glass close to the taking area, and a protective layer is fixed on the top of the contrast area.

[0012] Preferably, the taking area comprises a label plate and a groove, the label plate is located on one side of the base plate, and the top of the label plate is symmetrically provided with grooves.

[0013] Preferably, the groove is an arc-shaped groove, and stripes are evenly arranged inside the groove.

[0014] Preferably, reinforcing fibers are arranged inside the arc surface groove, and the reinforcing fibers are mesh fibers.

[0015] Preferably, circular positioning grooves are provided at four corners of the bottom of the base plate, and anti-slip sheets are provided inside the circular positioning grooves.

[0016] The beneficial effects of the utility model are:

[0017] The HE staining glass slide device provided by the utility model can limit the sample to a certain extent through the arc grooves communicating on both sides through the coordinated use of the taking area, the base plate, the scale line, the glass slide, the fixing plate and the arc groove, and the arc setting is more conducive to the cleaning of the glass slide, which is not only conducive to the stability of the sample but also reduces the risk of cross contamination, thereby improving the practicality of the microorganism staining glass slide device;

[0018] Through the coordinated use of the comparison area and the protective layer, the comparison area places the comparison sample inside for sample detection comparison, and the protective layer protects the top of the comparison area, reduces the wear and tear that affects the use of the glass slide, increases the use frequency of the microbial staining glass slide device, and thus reduces the use cost;

[0019] Through the coordinated use of the label plate, the grooves and the stripes, the label content is recorded on the label plate, and the tweezers are clamped through the grooves. The stripes increase the friction with the ends of the tweezers, making it easier to pick up and improve the stability of picking up, thereby facilitating the smooth progress of experimental testing.

[0027] The test sample is picked out and smeared on the slide glass 4. The size and diameter of the sample can be observed through the scale lines 3. The scale lines 3 set at the bottom of the slide glass 4 can reduce corrosion and maintain the clarity of the scale. The sample can have a certain limiting effect through the arc grooves 6 connected on both sides. At the same time, the arc setting is more conducive to the cleaning of the glass slide.

[0031] In this embodiment, the groove 10 is an arc-shaped groove, and stripes 11 are evenly arranged inside the groove 10 .

[0032] The arc groove not only makes it easier for the staff to hold the device, but the stripes 11 also increase the friction, making it more convenient to hold the device.

[0033] In this embodiment, reinforcing fibers are disposed inside the arc surface groove 6 , and the reinforcing fibers are mesh fibers.

[0034] The toughness of the arc surface groove 6 is enhanced by strengthening the mesh fibers, thereby improving the overall firmness.
