[0028] Special staining is the most basic pathological tissue chemical staining technology. During the process of dripping the reagent and incubating in a water bath, it is necessary to ensure that the special staining reagent completely and adequately covers the histological specimen to prevent the specimen from drying up. Currently, there is no special staining device for pathological histology. Usually, a conventional staining jar is used to add the staining reagent and then the glass slide is directly immersed in it, resulting in reagent waste, increased costs, and increased harmful liquid emissions. In order to solve the above problems, the utility model proposes a staining device for special staining of pathological histology and a medical and hygienic clinical testing equipment, aiming to provide a staining device for special staining of pathological histology and a medical and hygienic clinical testing equipment that reduces reagent waste, saves costs and is low in pollution. Figures 1 to 4The present invention is a structural schematic diagram of an embodiment of a slide staining device for special staining of pathological histology provided by the present invention.

[0029] Please refer to Figures 1 to 3 In one embodiment of the present invention, the staining device 100 for special staining of pathological histology includes a base plate 1 and a accommodating tube 2; the base plate 1 is provided with two protrusions 11 arranged in pairs, and a clamping interval 111 is formed between the two protrusions 11, and a slide 12 is clamped in the clamping interval 111; the accommodating tube 2 is cylindrical and has an accommodating cavity 21 therein to accommodate a pathological tissue block; one end of the accommodating tube 2 is provided with a clamping arm 22 protruding horizontally relative to each other to clamp with the two protrusions 11 and cover the slide 12.

[0030] The technical solution of the present invention is to place the pathological tissue block in the accommodating cavity 21 of the accommodating tube 2, then install the accommodating tube 2 on the holding section 111 of the substrate 1, and seal the accommodating tube 2 with a glass slide 12. At the same time, only special staining reagents need to be added to the accommodating tube 2 to ensure that the special staining reagents completely and adequately cover the histological specimens and prevent the specimens from drying up, without having to add reagents to a large-capacity container, thereby reducing reagent waste and saving costs.

[0031] In addition, please refer to Figure 1 and Figure 2 , the two protrusions 11, the glass slide 12, and the accommodating tube 2 are set as an observation group, and there are two observation groups, which are arranged at intervals on the substrate 1. It can be understood that the two protrusions 11, the glass slide 12, and the accommodating tube 2 are set as an observation group. In some embodiments, one substrate 1 carries one observation group, and generally, the observation group includes an experimental group and a control group. In this case, another substrate 1 is required to carry the observation group, and only two substrates 1 can be placed in the water bath, that is, each carrying the experimental group and the control group. Otherwise, too many substrates are placed and easy to confuse. Therefore, in other embodiments, the experimental group and the control group are set on the same substrate 1, and then more pathological tissue blocks can be heated in the water bath at the same time, thereby improving the efficiency of water heating. At the same time, the same substrate 1 carries both the experimental group and the control group, which is not easy to confuse with other experimental groups or the control group.

[0032] Furthermore, the substrate 1 is made of a hard plastic material. It is understood that the glass slide 12 needs to be held within the holding space formed by the two protruding bumps 11 provided on the substrate 1. This inevitably requires a certain degree of plastic deformation of the substrate 1 during the holding process. Therefore, the use of a hard plastic material for the substrate 1 allows for a certain degree of plastic deformation, facilitating the insertion of the glass slide 12 into the holding space. Furthermore, the high toughness of the hard plastic ensures stable and reliable holding even after repeated use.

[0033] In addition, please refer to Figure 1 The lower end surface of the substrate 1 is equipped with a counterweight 13 to allow the substrate 1 to sink into the water bath. It is understandable that in most cases, in order to accelerate the diffusion of the staining reagent into the pathological tissue block, high temperature can help accelerate the diffusion rate of the staining reagent, and most heating is to immerse the staining device 100 for special staining of pathological histology in a water bath for water bath heating. However, since the substrate 1 is made of hard plastic and the accommodating tube 2 is provided with the accommodating cavity 21, the substrate 1 cannot be immersed in water with the accommodating tube 2. Therefore, the lower end surface of the substrate 1 is equipped with the counterweight 13 to allow the substrate 1 to sink into the water bath. The counterweight 13 can be arranged in a plate shape on the lower side of the substrate 1, or it can be arranged in a plurality of blocks and evenly distributed on the lower end surface of the substrate 1. The specific arrangement form is not specifically limited here.

[0034] In addition, please refer to Figure 4 A silicone barrier layer 211 is provided around the sidewall of the accommodating chamber 21. It is understood that the dye diffuses upon heating and easily stains the accommodating tube 2. Therefore, the silicone barrier layer 211 is provided around the sidewall of the accommodating chamber 21. Since silicone is used, it is highly stable and will not react with or be stained by the dye even when heated, thus not affecting the final observation results and thereby ensuring the accuracy of the final pathology experiment.

[0035] In addition, please refer to Figure 1 The accommodating tube 2 is further provided with a cover 23 for sealing the accommodating chamber 21. It is understandable that in order to prevent impurities from entering the accommodating chamber 21 during the staining process of the staining reagent, or to prevent water from entering the accommodating tube 2 when the water bath is heated, the accommodating tube 2 is further provided with the cover 23 for sealing the accommodating chamber 21, thereby ensuring that no impurities enter the accommodating tube 2 when the staining reagent is staining the pathological tissue block, thereby affecting the experimental results, and at the same time avoiding the possibility of water entering the accommodating chamber 21 when the water bath is heated.

[0036] For further information, please refer to Figure 3 The cover 23 is also provided with an operating portion 231 for holding. It is understood that in order to facilitate the operator to seal the accommodating tube 2 with the cover 23 and to facilitate the removal of the cover 23 from the accommodating tube 2, the cover 23 is also provided with an operating portion 231, which is convenient for the operator to hold, thereby making it easier for the operator to seal the accommodating tube 2 or remove the cover 23 from the accommodating tube 2.

[0037] For further information, please refer to Figure 3 The end face of the cover 23 that is inserted into the accommodating chamber 21 is provided with a sealing ring 232. It is understood that in order to prevent water from entering the accommodating tube 2 during water bath heating and to prevent the liquid from volatilizing due to heating, the end face of the cover 23 that is inserted into the accommodating chamber 21 is provided with the sealing ring 232. The sealing performance of the sealing ring 232 prevents water from entering the accommodating tube 2 during water bath heating, thereby avoiding affecting the experimental results. In this embodiment, in order to further improve the sealing performance, the sealing ring 232 is provided with two circles.

[0038] For further information, please refer to Figure 3 The cover 23 further includes a connector 233, one end of which is connected to the cover 23 and the other end is connected to the accommodating tube 2. In some embodiments, the cover 23 and the accommodating tube 2 are separated. The accommodating cavity 21 of the accommodating tube 2 has different diameters to accommodate the sizes of various pathological tissue blocks. Therefore, corresponding to the accommodating tubes 2 of various diameters, the cover 23 should be provided one-to-one. If a separate arrangement is adopted, on the one hand, it is easy to find the cover 23 corresponding to the accommodating tube 2 among the many covers 23, which may easily cause the seal to fail or fail to seal the accommodating tube 2. On the other hand, the cover 23 may be easily lost due to repeated plugging and unplugging by the operator. Therefore, the cover 23 further includes the connector 233, one end of which is connected to the cover 23 and the other end is connected to the accommodating tube 2. In this way, the cover 23 will not be mixed up or lost.

[0039] The present invention also proposes a medical and health clinical testing equipment, which includes the staining device 100 for special staining of pathological histology. The specific structure of the staining device 100 for special staining of pathological histology refers to the above embodiment. Since the medical and health clinical testing equipment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
