Description

Technical Field

[0001] The utility model belongs to the technical field of biomedicine, and in particular relates to a fixing device for a glass slide. Background Art

[0002] In biological research, immunohistochemistry is an important technical method that can be used to study the relationship and mechanism of action between various biological molecules. Immunohistochemistry technology is widely used, including tumor research, gene expression analysis, pathogen detection and other fields. Among them, immunohistochemical staining is one of the most commonly used methods. Immunohistochemical staining uses the principles of immunology to couple specific antibodies with specific antigens or molecules on tissue sections, and then uses antibodies or avidins labeled with fluorescent, chemiluminescent and other signals for detection, and finally obtains information about tissue sections through image processing technology.

[0003] When conducting immunohistochemical staining experiments, glass slides are very important experimental materials. First, glass slides are used to carry and organize slices, which is the first step in immunohistochemical staining. Generally speaking, biological tissue slices that have been pre-treated are selected and then placed on glass slides. Next, the slices need to undergo a series of treatments, including immunofixation, immunowashing, immunohistochemistry, etc. During immunofixation and immunowashing, the role of the glass slide is to prevent the slices from moving or deforming. In addition, in some experiments, we will drop some liquid reagents, such as buffer, antibody solution, etc., on the glass slide to keep the slices moist. Finally, for the glass slides that have been treated with immunohistochemistry, they need to be washed, dehydrated and sealed for subsequent observation and analysis. In this process, special tweezers and tools are needed to remove and move the glass slides, which requires great care and stability. However, existing fixing devices often have some problems, such as the inability to stably fix the glass slides, easy displacement or tipping, and the inability to conveniently take and place the glass slides, which seriously affect the progress of the experiment and the accuracy of the results. In view of this, it is necessary to study a glass slide fixing device. Summary of the invention

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A fixing device for a glass slide comprises a limiting seat 1, a fixing component and a locking component for locking the fixing component. The limiting seat 1 is provided with a placement groove 101 for placing a glass slide 2 and a sealing plate 3.

[0021] The fixing assembly includes a fixing seat 4, a plurality of pressure covers 5 and a plurality of springs 6. The rear side of the fixing seat 4 is rotatably connected to the rear side of the top end of the limiting seat 1. A first connecting sleeve 102 is fixed to the rear side of the top end of the limiting seat 1. A second connecting sleeve 402 is arranged on the rear side of the fixing seat 4. The first connecting sleeve 102 and the second connecting sleeve 402 are rotatably connected together through a first pin shaft 7. A first spacing sleeve 8 is arranged between the first connecting sleeve 102 and the second connecting sleeve 402 to realize the rotation of the fixing seat 4 relative to the limiting seat 1.

[0022] Both sides of the fixing seat 4 are provided with a plurality of mounting channels 401 running through both ends thereof, and a first spring is inserted into the mounting channel 401. The bottom end of the first spring is fixedly connected to the pressure cover 5, and the top end is fixedly connected to the spring pressure cover fixed to the top of the fixing seat 4. The spring pressure cover is fixed to the fixing seat 4 by screws, and the expansion and contraction of the first spring can drive the pressure cover 5 to move up and down.
