The process of transferring cells from liquid samples to glass slides and labeling them is called liquid-based cell preparation.

[0021] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides a liquid-based cell preparation liquid circuit, including at least one group of reagent needle groups, the reagent needle group includes a liquid A reagent needle 9, a liquid B reagent needle 10, a cleaning liquid reagent needle 11, a transparent liquid reagent needle 12, a buffer solution reagent needle 13, and a waste liquid needle 14. The reagent needle group centrally arranges various reagent needles to reduce the physical size and save space. The structural design will be more optimized, making it easier to achieve miniaturization and lightweight of the equipment. A liquid reagent needle 9, B liquid reagent needle 10, cleaning liquid reagent needle 11, transparent liquid reagent needle 12, buffer reagent needle 13 are connected to dyeing reagent A liquid container 1, dyeing reagent B liquid container 2, cleaning liquid container 3, transparent liquid container 4, buffer container 5 through electromagnetic valve 1, electromagnetic valve 2, electromagnetic valve 3, electromagnetic valve 4, electromagnetic valve 5 and pipelines respectively; dyeing reagent A liquid container 1, dyeing reagent B liquid container 2, cleaning liquid container 3, transparent liquid container 4, buffer container 5 are connected to the compressed air device through pipelines and electromagnetic reversing valves; electromagnetic valve 1, electromagnetic valve 2, electromagnetic valve 3, electromagnetic valve 4, electromagnetic valve 5, and electromagnetic reversing valve are electrically connected to the control device respectively. The control device is PIC. The compressed air device provides positive pressure to dyeing reagent A liquid container 1, dyeing reagent B liquid container 2, cleaning liquid container 3, transparent liquid container 4, and buffer container 5, so that the liquids therein are added to the corresponding reagent needles in the reagent needle group respectively. The driving force provided by air pressure can reduce the failure of the liquid circuit system and make the use performance more stable. The control system realizes quantitative multiple liquid addition at each reagent needle position by controlling solenoid valve one, solenoid valve two, solenoid valve three, solenoid valve four, solenoid valve five and solenoid reversing valve, while also reducing the number of liquid circuit pumps and control solenoid valves used and simplifying the liquid circuit.
[0022] The waste liquid needle 14 of the reagent needle group is connected to the sedimentation bin 7 through a filter device and a pipeline. The filter device is preferably a diaphragm pump, which discharges the waste liquid of the reagent needle group into the sedimentation bin 7. The sedimentation bin 7 is connected to the separation liquid container 6 through an electromagnetic valve 11, and the separation liquid is placed in the separation liquid container 6. The electromagnetic valve 11 is electrically connected to the control device, and the separation liquid container 6 is connected to the compressed air device, and the separation liquid is added to the sedimentation bin 7 by controlling the electromagnetic valve 11.
[0023] In this embodiment, it is preferred that there are four reagent needle groups; they are reagent needle group 1, reagent needle group 2, reagent needle group 3 and reagent needle group 4. Reagent needle group 1 and reagent needle group 2 are connected to the dyeing reagent A liquid container 1, dyeing reagent B liquid container 2, cleaning liquid container 3, transparent liquid container 4 and buffer solution container 5 through electromagnetic valve 1, electromagnetic valve 2, electromagnetic valve 3, electromagnetic valve 4, electromagnetic valve 5 and pipelines, tees 8 and other equipment; reagent needle group 3 and reagent needle group 4 are connected to the dyeing reagent A liquid container 1, dyeing reagent B liquid container 2, cleaning liquid container 3, transparent liquid container 4 and buffer solution container 5 through electromagnetic valve 6, electromagnetic valve 7, electromagnetic valve 8, electromagnetic valve 9, electromagnetic valve 10 and pipelines, tees 8 and other equipment; electromagnetic valve 6, electromagnetic valve 7, electromagnetic valve 8, electromagnetic valve 9 and electromagnetic valve 10 are electrically connected to the control device.

The two groups of reagent needle groups share a solenoid valve control, which further reduces the number of liquid circuit pumps and control solenoid valves used and simplifies the liquid circuit. Of course, it is understandable that in other embodiments, after being equipped with corresponding solenoid valves, pipelines, tees 8 and other equipment, the number of reagent needle groups can be expanded to six groups, eight groups, etc. In order to simplify the pipeline for waste liquid discharge, reagent needle group 1 and reagent needle group 2 are connected to sedimentation bin 7 through filter device 1 and pipelines; reagent needle group 3 and reagent needle group 4 are connected to sedimentation bin 7 through filter device 2 and pipelines.
