Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary operation devices for immune laboratories, in particular to a slide dewatering and circle drawing device. Background Art
[0002] In the process of immunohistochemical staining, immunofluorescence staining, in situ hybridization, special staining and other experiments, it is necessary to first dewax and hydrate the tissue sections, then wipe the liquid on the edge of the tissue on the slide with a thin paper, and then use an immunohistochemical pen to draw circles around the specimen on the slide, dry for 10-15 seconds, and then immerse the slide in PBS buffer. During the operation, because the slide is a horizontal surface with a relatively smooth surface, it is necessary to ensure that the antibody completely covers the tissue to be tested, avoid excessive antibody flow range, and avoid dry slices and peeling caused by the loss of surface reagents.
[0003] The existing water absorption and circle drawing steps are generally performed manually, which is cumbersome, increases processing time, and affects work efficiency. In the disclosed prior art, CN 210376382 U discloses an immunohistochemical circle drawing device, which adjusts the distance between the rotating rod and the inclined rod by telescopic adjustment of the electric telescopic rod, so as to adjust the circle size of the circle drawing device, and draws circles by rotating the rotating rod. However, this solution has a complex structure, requires power supply, and has a high cost. In addition, the operation of rotating the rotating rod is no different from rotating the immunohistochemical pen, and manual circular drawing operation is still required, which does not achieve a convenient and quick effect.
[0004] In another prior art disclosed, CN206593933U discloses a glass slide wiper, which uses a motor to drive a threaded tube with a water-absorbing layer at the bottom to descend and absorb water from the glass slide. However, the device still needs to be manually rotated and driven by a motor, which is not only expensive, but also easy to generate excessive pressure on the glass slide, causing the glass slide to be crushed.
[0005] Therefore, it is necessary to improve the existing technology and develop a low-cost, easy-to-operate glass slide dewatering and circle drawing device, thereby saving manpower and financial resources and improving work efficiency. Utility Model Content
