Description

Technical Field

[0001] This utility model belongs to the field of histological slide preparation tools, specifically relating to a dispensing box for multiple labeling staining reagents for tissue sections. Background Technology

[0002] In the preparation of tissue sections, to improve the resolution of the specimen under an optical microscope, the tissue sections laid flat on the slide need to be stained. A variety of staining reagents are used in the staining process, therefore, staining kits that package multiple staining reagents are available on the market. Existing staining kits mostly contain large-capacity bottles of staining reagents. When using these reagents to stain tissue sections, operators need to take each staining reagent sequentially. During this process, on the one hand, operators need to use droppers to draw the staining reagents, and the large volume of reagents can easily lead to contamination and waste. On the other hand, according to standard operating procedures, after opening the cap of the corresponding reagent bottle to draw the liquid, the operator needs to immediately close the cap. Therefore, during the entire staining process, the operator needs to repeatedly pick up and put down the dropper and repeatedly rotate the cap, which is inconvenient and limits operational efficiency. To address these problems, this invention proposes a tissue section multiple-label staining reagent dispensing box. Utility Model Content

[0003] The purpose of this invention is to provide a tissue section multiple labeling staining reagent dispensing box in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] This utility model provides a tissue section multiple labeling staining reagent dispensing box, including a box body and a box lid. The box body has a plurality of reagent dispensing components arranged in a linear manner. Each reagent dispensing component includes a back plate, and one side of the back plate is provided with a membrane. The membrane includes a liquid storage part, a flow guiding part and a sealing part. The membrane and the back plate form a sealed cavity for filling with staining reagent.

[0006] As a further optimization of this utility model, the liquid outlet of the guide section is located at one corner of the back plate.

[0007] As a further optimization of this utility model, the back plate is provided with a fold line groove.

[0008] As a further optimization of this utility model, the reagent dispensing component is provided with snap-fit ​​components on both sides, and the inner wall of the box is provided with a number of positioning components that correspond one-to-one with the snap-fit ​​components.

[0009] As a further optimization of this utility model, the outlet end of the guide section is fixedly connected to the inner wall of the box body through a sealing strip.

[0010] The beneficial effects of this utility model are as follows:

[0011] This tissue section multiple labeling staining reagent dispenser uses a backplate and a membrane to encapsulate the staining reagent, achieving the effect of dispensing the staining reagent. During repeated staining, it provides a separate reagent dispenser for each staining step. When using it, the operator does not need to use additional tools to get the reagent; they only need to squeeze the membrane to squeeze out the staining reagent from the dispenser. The method of use is convenient and efficient. Moreover, each reagent dispenser is independent of the others, and each dispenser is sealed before use, which greatly reduces the probability of staining reagent contamination. This comprehensively improves the convenience and efficiency of operation when staining tissue sections. Attached Figure Description

[0018] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1-5 As shown, the tissue section multiple labeling staining reagent dispensing box of this embodiment includes a box body 1 and a box lid 2. The box body 1 and the box lid 2 can be fixed in one go by adhesive or tape wrapping. It is preferably made of plastic. The box body 1 is provided with a number of reagent dispensing components arranged in a linear manner. The reagent dispensing components include a back plate 3. A film is provided on one side of the back plate 3. The film includes a liquid storage part 4, a flow guiding part 5 and a sealing part 6. The film and the back plate 3 form a sealed cavity for filling the staining reagent.

[0021] When using this tissue section multiple labeling staining reagent dispenser to package staining reagents, different staining reagents can be distinguished by setting different colored back plates 3. When staining tissue sections, simply take the corresponding reagent dispenser in the staining order. After taking it out, the operator only needs to squeeze the film to pressurize the sealed cavity, so that the staining reagent breaks through the seal 6 to complete the output. No additional tools are needed during the operation, eliminating the need for repeated bottle opening and avoiding the problem of staining reagent contamination.

[0022] Preferably, the outlet of the guide section 5 is located at one corner of the back plate 3. The location of the guide section 5 at one corner makes it easier to observe the position of the outlet, which facilitates the accurate dripping of the staining reagent onto the location of the tissue section on the glass slide.

[0023] Preferably, the back plate 3 is provided with a fold line groove. By pinching the back plate 3 and folding it along the fold line groove, the film can be squeezed evenly and thoroughly, thereby completely releasing the dyeing reagent in the sealed cavity, further improving the ease of operation.

[0024] Preferably, the reagent dispensing components are provided with snap-fit ​​components 7 on both sides, and the inner wall of the box body 1 is provided with several positioning components 8 that correspond one-to-one with the snap-fit ​​components 7. With the cooperation of the snap-fit ​​components 7 and the positioning components 8, the back plate 3 can be fixed vertically, which can avoid the problem of the various reagent dispensing components squeezing each other, causing damage to the coating and leakage of dyeing reagents, and also facilitates quick and easy use.

[0025] Preferably, the outlet end of the guide section 5 is fixedly connected to the inner wall of the box body 1 by the sealing strip 9. When not disassembled, the sealing section 6 is completely covered by the sealing strip 9. When the reagent dispenser is taken out, the sealing strip 9 is naturally torn off, and the sealing section 6 is exposed. The sealing strip 9 not only reinforces the reagent dispenser, but also provides a double sealing effect in conjunction with the sealing section 6. Therefore, the sealing can be made of an easily breakable film. The sealing strip 9 can prevent the sealing section 6 from being damaged, thereby ensuring the sealing performance. The easily breakable film allows the staining reagent to be dispensed with only slight pressure when the film is squeezed. The staining reagent can be squeezed out slowly and will not cause excessive impact when it comes into contact with the tissue section.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
