[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] The independent micro-staining chamber unit in the embodiment of the utility model realizes the clamping of the glass slide through the independent micro-staining chamber, the fixed clamping parts and the movable clamping mechanism to ensure that the glass slide will not be thrown out and broken during high-speed rotation, thereby ensuring the effectiveness of staining.
[0021] like Figure 1 - Figure 3 As shown, the independent micro-staining chamber unit includes an independent micro-staining chamber 1, a fixed clamping member 2 and a movable clamping mechanism 3. The fixed clamping member 2 is arranged at one end of the independent micro-staining chamber 1, and the movable clamping mechanism 3 is arranged at the other end of the independent micro-staining chamber 1. A glass slide 5 to be stained can be placed between the fixed clamping member 2 and the movable clamping mechanism 3. The movable clamping mechanism 3 includes a movable clamping column 31, a spring 32 and a cover plate 33. A slide groove 34 is arranged at the end of the independent micro-staining chamber 1, and the movable clamping column 31 is slidably arranged in the slide groove 34. The spring 32 is arranged in the slide groove 34 and abuts against the movable clamping column 31. The cover plate 33 is arranged on the slide groove 34.
[0022] Through the above arrangement, the glass slide 5 can be clamped between the fixed clamping part 2 and the movable clamping column 31 during staining. Due to the action of the spring 32, the movable clamping column 31 can always clamp the glass slide 5, thereby avoiding the flying phenomenon of the glass slide 5 during high-speed rotation.
[0023] In some embodiments, the fixed clamping member 2 includes a glass slide fixing oblique clamping column, and the side of the glass slide fixing oblique clamping column that abuts against the glass slide is tilted downward and inward, so that the glass slide can be pressed by the glass slide fixing oblique clamping column and will not warp up.
[0024] In other embodiments, the side of the movable clamping column 31 that contacts the glass slide is tilted downward and inwardly arranged, so that the glass slide 5 can also be pressed by the movable clamping column 31 and will not be lifted up.
[0025] like Figure 3 As shown, a support step 35 is provided in the slide groove 34, and the upper part of the movable clamping column 31 and the spring 32 are both provided on the support step 35. By providing the support step 35, the upper part of the movable clamping column 31 and the bottom of the independent micro-staining chamber 1 are at a certain height to prevent the staining liquid from being immersed, and the spring 32 is not immersed in the staining liquid to cause cross contamination of the sample.
[0026] In other embodiments, a sliding step 11 is provided at the bottom of the independent micro-staining chamber 1. The sliding step 11 is in a long strip shape and is arranged close to one end of the movable column 31. The sliding step 11 is spaced apart from the movable column 31. The sliding step 11 is helpful in guiding when inserting the glass slide and can prevent the movable column 31 from falling off.
[0027] like Figure 3 As shown, a support column 12 is provided at the bottom of the independent micro-staining chamber 1, and the support column 12 plays a role in supporting the glass slide, so that when the front side of the glass slide faces the bottom, it is conducive to the staining liquid soaking on the glass slide sample.
[0028] In other embodiments, a centrifugal slide staining tray 4 for preventing flying slides is also disclosed, such as Figure 1As shown, the centrifugal slide staining tray 4 for preventing flying slides comprises a tray body 41, and a plurality of independent micro-staining chamber units are arranged around the edge of the tray body 41, so that a plurality of slides can be loaded at one time for staining.
[0029] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
