[0001] This utility model relates to the field of cell preparation technology, and in particular to a centrifugal liquid-based cell preparation machine. Background Technology

[0002] In the field of modern medical diagnostics, liquid-based cytology is a widely used and important testing method, playing a crucial role, especially in the early screening of diseases such as cervical cancer and lung cancer. The centrifugal liquid-based cytology slide preparer, as the core equipment for liquid-based cytology testing, directly affects the accuracy and efficiency of the test results.

[0003] Traditional centrifugal liquid-based cell slide preparation machines require thorough cleaning after each use to prevent cross-contamination caused by sample residue, which could affect the accuracy of subsequent test results. However, most existing centrifugal liquid-based cell slide preparation machines have significant design flaws in their centrifuge cups. These traditional devices typically use a complex connection method between the centrifuge cup and the slide preparation machine body, secured by multiple small screws, or employ an integrated nested structure. This means that operators need to spend a lot of time and effort to disassemble the centrifuge cup when they want to thoroughly clean it, which is time-consuming and laborious.

[0004] Therefore, it is necessary to provide a centrifugal liquid-based cell slide preparation machine to solve the above-mentioned technical problems. Utility Model Content

[0029] The working principle of the centrifugal liquid-based cell slide preparation machine provided by this utility model is as follows:

[0030] When it is necessary to clean the centrifuge cup 4, press down the lever 22. As the lever 22 moves downward, it will drive the limiting slider 17 downward along the vertical groove 20. At this time, the limiting slider 17 will compress the telescopic spring 18 downward. Simultaneously, the limiting slider 17 will drive the vertical slider 16 to slide downward to release the restriction on the limiting block 3. The centrifuge cup 4 can then be removed for cleaning. After cleaning, the centrifuge cup 4 can be inserted into the mounting slot 15 and rotated. At this time, the limiting block 3 will squeeze the vertical slider 16. After passing the vertical slider 16, the telescopic spring 18 will use its own elasticity to push the vertical slider 16 to reset and restrict the limiting block 3.

[0031] Compared with related technologies, the centrifugal liquid-based cell slide preparation machine provided by this utility model has the following beneficial effects:

[0032] When it is necessary to clean the centrifuge cup 4, the pressure lever 22 can be pressed down. As the pressure lever 22 moves downward, it will drive the limiting slider 17 downward along the vertical slide groove 20. At the same time, the limiting slider 17 will drive the vertical slider 16 downward to release the restriction on the limiting block 3. At this time, the centrifuge cup 4 can be removed for cleaning. This device adds a quick disassembly function for the centrifuge cup 4, which can be removed for thorough cleaning. Thorough cleaning can effectively reduce the risk of cross-contamination between different samples and avoid inaccurate test results due to cross-contamination between samples. By making it easy to clean the centrifuge cup, the cleanliness of the slide preparation machine can be better maintained, ensuring the accuracy of the test, thereby achieving the effect of improving the accuracy of the test.
