Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of instruments for pathological cells, diagnostics, and pathological biomolecular diagnostics, and in particular to a cell sheet device, and in particular to a fully automatic liquid-based thin layer cell sheet making device and a sheet making method. Background Art
[0002] In medical testing and biological research, it is often necessary to prepare and stain cell samples for better observation. Traditional preparation and staining processes are all done manually. However, manual smears contain a large amount of cell accumulation and interfering factors such as red blood cells, mucus, and impurities, which affect the correct diagnosis. There will be a false negative rate of 2% to 50%, and it is easy to cause eye fatigue for the diagnostic staff. It is time-consuming, labor-intensive, and inefficient. In recent years, the application of liquid-based cytology technology has made new breakthroughs in cell preparation and staining technology. Liquid-based cytology technology is a method of preserving exfoliated cells in cell preservation fluid. It can effectively remove interfering diagnostic factors such as red blood cells, mucus, and impurities, and disperse and dissociate cell clusters, significantly improving the quality of pathological cytology preparation. The cell structure and background are clear, which is conducive to differential diagnosis and significantly reduces the false negative rate.
[0003] Through the search of literature and patents, patents and documents related to cell preparation, such as the Chinese patent document with publication number CN106018033A and publication date October 12, 2016, entitled "Fully Automatic Liquid-Based Thin-Layer Cell Slide Preparation and Staining Device," disclose a fully automatic liquid-based thin-layer cell slide preparation and staining device. In the technical solution disclosed in this patent document, the device can fully automatically implement the mechanisms of setting out, pipetting, slide preparation, and staining. Although it can automatically prepare slides to a certain extent and partially replace manual operations, the slide preparation and staining device will result in different staining depths at different temperatures and lacks effective quality control. At the same time, it can only achieve setting out and staining, but cannot achieve automation of the entire process such as cleaning and collecting slides. Therefore, manual participation is still required, which increases labor costs and production time, which is not conducive to reducing the cost of the entire process. Summary of the Invention

The inner layer of the heat-insulating layer close to the turntable body is provided with heat-insulating cotton, while the outer layer away from the turntable body is provided with a metal cladding.
3. The constant temperature fully automated cell preparation integrated device according to claim 1, characterized in that: The temperature control component controls the temperature of the sedimentation cup in the sedimentation cup accommodating tank to be 20-60°C.
4. The constant temperature fully automated cell preparation integrated device according to claim 1, characterized in that: The slide adding mechanism includes a slide box with an opening and a pushing device. The pushing device pushes the slides stored in the slide box to the slide entrance position through the opening, and then the slides enter the slide card slot of the rotating sedimentation plate from the slide entrance.
5. The constant temperature fully automated cell preparation integrated device according to claim 1, characterized in that: The cleaning and sample loading integrated device further comprises a robotic arm, one end of which is connected to the Z-axis adjustment mechanism, and the other end of which is connected to the fluid of the cleaning liquid component and the sample loading component; The Z-direction adjustment mechanism reciprocates in the vertical direction to adjust the relative height of the robotic arm with respect to the turntable body.
6. The constant temperature fully automated cell preparation integrated device according to claim 5, characterized in that: The robotic arm has an arc-shaped portion.
7. The constant temperature fully automated cell preparation integrated device according to claim 1, characterized in that: The sheet discharging mechanism comprises a sheet discharging fork and a driving mechanism connected to the sheet discharging fork.
8. A method for using the constant temperature fully automated cell preparation integrated device according to any one of claims 1 to 7, characterized in that: The steps include: Step S1: The slide to be loaded enters the rotating sedimentation tray through the slide inlet and rotates intermittently along with the turntable body; Step S2: The cleaning liquid component and the sample loading component in the cleaning and loading integrated device add liquid to two different sedimentation cups respectively along with the intermittent rotation of the turntable body. At this time, the sample loading component adds sample to the glass slide to be loaded through the sedimentation cup, while the cleaning component cleans the sedimentation cup that has been loaded with sample, and the loaded glass slide is removed from the slide outlet.
