Description

Technical Field

[0002] Generally speaking, most microorganisms, such as bacteria and protozoa, are composed of a single cell, i.e., single-celled organisms. Higher plants and higher animals are multicellular organisms. Cells can be divided into two categories: prokaryotic cells and eukaryotic cells. However, some people have proposed that they should be divided into three categories, that is, to separate archaic cells, which originally belonged to prokaryotic cells, as a separate category. The discipline that studies cells is called cell biology.

[0003] Currently, most cell screening, cleaning, and arranging operations require manual completion, resulting in low automation and inefficiency. Therefore, an intelligent automatic cell cleaning and screening device is proposed. Summary of the Invention

[0046] Servo motor 11 provides power for the rotation of rotary platform 28;

[0047] The petri dish cleaner 19 has two waste tubes 30 inside. A negative pressure chamber 29 is opened inside one end of the petri dish cleaner 19. One side of the negative pressure chamber 29 is connected to one end of each of the two waste tubes 30.

[0050] Two check valves cause the liquid in the two waste pipes 30 to flow in opposite directions;

[0051] The vacuum cell suction device 15 has a suction chamber 40 on its inner side, and a piston 41 is slidably connected to the inner side of the suction chamber 40. A rotating platform 28 is fixedly connected to one end of the vacuum cell suction device 15, and a capillary tube is provided on the inner side of the rotating platform 28. One end of the capillary tube is connected to one end of the suction chamber 40.

[0052] The rotary platform 28 is used to aspirate cells. When the cells enter the aspiration chamber 40, the cells rub against the liquid, thereby washing the cells.

[0053] A drive motor 37 is provided on the inner side of the motor base 35, and a connecting seat 36 is provided on the power output end of the drive motor 37. A placement platform shaft 6 is provided on the bottom of the petri dish placement platform 2, and one end of the placement platform shaft 6 is inserted into the inner side of the connecting seat 36.

[0054] The drive motor 37 controls the rotation of the petri dish placement stage 2 through the connecting seat 36 and the placement stage shaft 6. The placement stage shaft 6 cooperates with the connecting seat 36 to transmit the power of the drive motor 37 to the petri dish placement stage 2.

[0055] The inner side of the housing 1 is provided with a connecting wire 33 and a power supply 34. The power supply 34 is connected in series with the photoelectric switch 24, the status indicator light 21, and the photoelectric switch 24 via the connecting wire 33. The power supply 34 is a 24V battery. The photoelectric switch 24 is model E3S-GS30E4. The status indicator light 25 and the status indicator light 21 are both LED lights, model WD06L.

[0056] The light colors of the status indicator 25 and the status indicator 21 can display the working status, and the intelligent image processing system 13 can directly control the status of the status indicator 25.

[0057] A microfluidic air pump 12 is provided at one end of the air passage 14, and an air passage 14 is provided at one end of the microfluidic air pump 12. One end of the air passage 14 is fixedly connected to one end of the vacuum cell suction and release device 15.

[0058] The microfluidic air pump 12 uses a vacuum cell aspirator 15 to aspirate, release, arrange, exchange liquid, and identify cells.

[0059] The specific implementation method is as follows: Initial state: The culture dish containing the cells to be washed is placed inside the push plate 17 on the top of the sample placement stage 18.

[0060] Step 1: Control the movement of the push plate 17. The push plate 17 of the sample placement stage 18 pushes the clean culture dish to the top of the culture dish placement stage 2. During the movement of the push plate 17, the top of the photoelectric switch 24 briefly passes by. The photoelectric switch 24 senses the movement of the push plate 17, and the status indicator light 21 will light up red. The intelligent image processing system 13 will mark the culture dish placement stage 2 as a sample to be cleaned.

[0061] Simultaneously, the culture medium dispenser 20 discharges the culture medium from the culture medium tank into a clean culture dish on top of the culture dish placement platform 2 through the connecting pipe 22. The drive motor 37 controls and drives the connecting seat 36 to rotate. The connecting seat 36 drives the culture dish placement platform 2 to rotate through the placement platform shaft 6, so that the culture medium is evenly spread on the inner side of the culture dish placement platform 2. The servo motor 11 controls and drives the rotary platform 28 to rotate. The rotary platform 28 drives the rotary conveyor belt 3. The rotary conveyor belt 3 and the rotary platform 28 drive the motor base 35 to rotate. The motor base 35 drives the culture dish placement platform 2 to rotate around the central axis of the rotary platform 28 on the top of the shell 1. Different culture dish placement platforms 2 are rotated to the positions corresponding to the sample placement platform 18 in sequence. Then, as needed, several clean culture dishes are automatically placed on the top of the culture dish placement platform 2, and then culture medium is added one by one. The first clean culture dish contains cells.

[0062] Step 2: Cell aspiration: When the first clean culture dish is conveyed to the vacuum cell aspirator 15, the microfluidic air pump 12 starts and generates negative pressure at one end of the vacuum cell aspirator 15 through the air passage 14. The piston 41 inside the vacuum cell aspirator 15 moves, and the inner cavity of the vacuum cell aspirator 15 on one side of the piston 41 generates suction force on the outside through the rotating platform 28. Based on the image captured by the vacuum cell aspirator 15, the rotating platform 28 aspirates all the cells in the clean culture dish containing cells into the syringe. Then the conveyor belt continues to convey the cells, and the status indicator light 25 of the culture dish placement platform 2 containing the clean culture dish turns off.

[0063] Step 3: Initial Cleaning: When the second culture dish placement stage 2, carrying a clean culture dish, is transported to the area under the high-definition high-magnification electron microscope 16, the vacuum cell aspirator 15 releases cells under the control of the microfluidic air pump 12. Simultaneously, the drive motor 37 rotates the culture dish placement stage 2 at a controlled speed, working in coordination with the vacuum cell aspirator 15 to arrange the cells evenly in a circular pattern on the culture dish placement stage 2. The system identifies and marks normal cells using images acquired by the high-definition high-magnification electron microscope 16. Based on the marked position information, the system then uses the vacuum cell aspirator 15 to aspirate normal cells. After aspiration, the conveyor belt continues to transport the cells, and the intelligent image processing system 13 controls the status indicator light 25 inside the second culture dish placement stage 2 to turn off.

[0064] Step 4: Secondary Cleaning: When the third culture dish stage 2, carrying a clean culture dish, is brought to the area below the high-definition high-power electron microscope 16, the vacuum cell aspirator 15 releases the cells. Simultaneously, the culture dish stage 2 rotates at a controlled speed, working in tandem with the vacuum cell aspirator 15 to arrange the cells evenly in a circular pattern. The system then uses the image acquired by the high-definition high-power electron microscope 16 to identify and mark normal cells. The vacuum aspirator then picks up normal cells based on the marked position information. After the picking is complete, the conveyor belt continues to transport the cells, and the intelligent image processing system 13 controls the status indicator light 25 of the culture dish stage 2 to turn off.

[0065] Step 5: When the fourth culture dish placement stage 2, carrying a clean culture dish, is brought to the area below the high-definition high-magnification electron microscope 16, the vacuum cell aspirator 15 releases the cleaned cells, and the intelligent image processing system 13 controls the status indicator light 25 on the top of the culture dish placement stage 2 to illuminate. When the first three culture dish placement stages 2, carrying culture dishes, reach the positions corresponding to the culture dish cleaner 19, the stepper motor 31 drives the blades 32 to rotate. The change in the rotation direction of the blades 32 changes the flow direction of the liquid in the negative pressure chamber 29. When the negative pressure chamber 29 absorbs liquid, it draws the liquid from the culture dish into the inner cavity of the negative pressure chamber 29. The negative pressure chamber 29 then sends the liquid through a one-way valve and connecting pipe 3 27 to the waste liquid storage tank 9. When the negative pressure chamber 29 discharges liquid, it draws the cleaning liquid from the cleaning liquid storage tank 5 through a one-way valve, waste pipe 30, and connecting pipe 2 26, and discharges the cleaning liquid into the culture dish. Then, the negative pressure chamber 29 draws the excess cleaning liquid from the culture dish into the inner cavity of the waste liquid storage tank 9.
