They can produce daughter cells with exactly the same phenotype and genotype as themselves, as well as specialized cells that make up the body's tissues and organs. They can also differentiate into progenitor cells. After cultivating the cells under different conditions, they need to be stained and then observed to see if there are any missing or deformed shapes.

[0016] The present invention has the following beneficial effects:

[0017] (1) The cell detection device is provided with a placement plate, a support frame, a transmission frame and a transmission member. After a culture dish is placed on the placement plate, the transmission member can move upward to cause the arc-shaped clamping plates on the placement plate to move toward each other, thereby fixing the culture dish. Afterwards, after moving downward, the transmission frame can be driven to vibrate by vibration, thereby vibrating the culture dish on the placement plate.

[0035] Specifically, a driving motor 8 is fixedly connected to the bottom of the supporting bottom cover 1, and a rotating shaft 9 is fixedly connected to the end of the output shaft of the driving motor 8. The rotating shaft 9 movably penetrates the supporting bottom cover 1 and is fixedly connected to the supporting frame 3. The bottom of the supporting frame 3 is movably connected to the inner wall of the supporting bottom cover 1 through a connecting bearing; the staining frame 2 is fixedly connected to the supporting frame 3 by screws, and a laser transmitter 10 is fixedly connected to the staining frame 2. The positions corresponding to the placement plates 4 on the supporting frame 3 are fixedly connected with laser receivers 11. When staining is required, after the laser receiver 11 receives the optical signal of the laser transmitter 10, the controller cuts off the power to the driving motor 8, and the extrusion component pushes the dye out of the liquid outlet pipe on the staining frame 2. At the same time, the transmission frame 5 drives the placement plate 4 to rotate, so that the dye is in uniform contact with the cells inside the culture dish.

[0036] The extrusion component includes a driving motor 12 and a threaded rod 13. The driving motor 12 is fixedly connected to the bottom of the dyeing frame 2. The output shaft thereof movably penetrates the dyeing frame 2 and is fixedly connected to one end of the threaded rod 13. A piston 14 is threadedly sleeved on the surface of the threaded rod 13. A guide block 15 is fixedly connected to the surface of the piston 14. The surface of the guide block 15 is movably connected to the inner wall of the dyeing frame 2.

[0037] In this embodiment, when one of the placement trays 4 moves to the dyeing position, the laser emitted by the laser transmitter 10 on the dye will be received by the laser receiver 11, and the received light signal will be transmitted to the processor. After processing by the processor, the driving motor 8 is powered off and self-locked through the controller, so that the support frame 3 stops rotating. At this time, the circular tube portion 501 on the rotating member 17 contacts the transmission member, and the teeth on the circular tube portion 501 can engage with the teeth on the transmission member 7. Then the driving motor 12 is started, driving the threaded rod 13 and the transmission pulley 18 on its output shaft to rotate. The rotation of the threaded rod 13 can cause the piston 14 on it to move upward, so that the dye inside the dyeing frame 2 can be pushed out of the dyeing tube.

[0038] Specifically, a support plate 16 is fixedly connected to the surface of the dyeing frame 2, a rotating member 17 is fixedly connected to the bottom of the support plate 16, a transmission pulley 18 is fixedly sleeved on the output shaft of the driving motor 12, and the rotating member 17 is connected to the transmission pulley 18 through belt transmission; the transmission frame 5 includes a circular tube portion 501 and a support portion 502, the support portion 502 is fixedly connected to the top of the circular tube portion 501, the top of the support portion 502 is fixedly connected to the surface of the placement plate 4, the surface of the circular tube portion 501 is fixedly connected with teeth meshing with the rotating member 17, and the placement plate 4 is connected to the support frame 3 through a fixed bearing.

[0039] In this embodiment, the transmission pulley 18 rotates the rotating member 17 through the belt, which can drive the circular tube portion 501 to rotate, and the placement plate 4 can be rotated through the support portion 502 on the circular tube portion 501, and the culture dish can be rotated, so that the dye can be evenly dripped into the culture dish.

[0040] Specifically, the transmission member 7 includes an intermediate portion 701, an abutting portion 702 and an adjusting portion 703. The abutting portion 702 is integrally formed at the top of the intermediate portion 701, and the adjusting portion 703 is integrally formed at the bottom of the intermediate portion 701. The surface of the intermediate portion 701 is uniformly arrayed with a plurality of external teeth 19, and the interior of the circular tube portion 501 is uniformly arrayed with a plurality of internal teeth 20, and the surface of the external teeth 19 is movably connected to the surface of the internal teeth 20; a toothed member is arranged on the abutting portion 702, and after the rotating member 17 moves upward, the external teeth 19 are disengaged from the internal teeth 20, and the adjusting portion 703 drives the rotating member 17 to rotate, so that the toothed member on the abutting portion 702 causes the arc-shaped clamping plate 6 to move away from or toward each other through the transmission component; a connecting spring 21 is fixedly connected to the surface of the abutting portion 702, and one end of the connecting spring 21 is connected to the interior of the circular tube portion 501 through a limit bearing.

[0041] A vibration-boosting plate 22 is fixedly connected to the inside of the supporting bottom cover 1 on the same side of the detection position and the dyeing position. Both sides of the vibration-boosting plate 22 are provided with inclined surfaces facing the bottom of the supporting bottom cover 1. A number of vibration points are evenly arrayed on the bottom surface of the vibration-boosting plate 22, and a number of baffle bars 23 are fixedly and evenly arrayed on the top surface of the adjustment part 703.

[0042] In this embodiment, an inclined surface is provided on the vibration-assisting plate 22. Under the action of the inclined surface, the adjusting portion 703 drives the entire rotating member 17 to move downward. At this time, the connecting spring 21 is compressed to the minimum. A plurality of baffles 23 are evenly arranged in an array on the adjusting member. At the same time, a plurality of vibration points are fixedly connected to the vibration-assisting plate 22. The baffles 23 contact the vibration points and vibrate. High-frequency and low-amplitude vibrations can be achieved according to the density of the baffles 23 and the density of the vibration points, so that the rotating frame is vibrated through the rotating member 17, and then the rotation of the placement plate 4 is achieved, so that the components of the cell fluid and the dye can be mixed, which is convenient for rapid dyeing.

[0043] Specifically, an unlocking position and a fixing position are sequentially arranged inside the supporting bottom cover 1 at the same side of the detecting position and the dyeing position. A rising arc plate 24 is fixedly connected at the detecting position and the dyeing position inside the supporting bottom cover 1 for moving the rotating member 17 upward. An outer tooth plate 25 with adjustable position is arranged on the unlocking position of the supporting bottom cover 1. A screw rod 26 is fixedly connected to the surface of the outer tooth plate 25. One end of the screw rod 26 is threadedly penetrates the supporting bottom cover 1 and extends to the outside thereof. A guide rod 27 is also fixedly connected to the surface of the outer tooth plate 25. The guide rod 27 is movably connected to the supporting bottom cover 1. An inner tooth plate 28 is fixedly connected to the fixed position of the supporting bottom cover 1. When the adjusting portion 703 moves to the position of the inner tooth plate 28, it rolls on the inner tooth plate 28 to rotate the rotating member 17, and drives the arc-shaped clamping plate 6 to move toward each other through the gear-moving member on the abutting portion 702.

[0044] The geared member includes an upper gear ring 29 and a lower gear ring 30. The upper gear ring 29 is connected to the surface of the abutment portion 702 through a positioning bearing, and the lower gear ring 30 is slidably connected to the surface of the abutment portion 702 through a connecting block. Tooth blocks 31 are provided on opposite sides of the upper gear ring 29 and the lower gear ring 30. The tooth blocks 31 on the upper gear ring 29 and the tooth blocks 31 of the lower gear ring 30 are arranged opposite to each other, and magnet sheets 32 are fixedly connected to the surfaces of the tooth blocks 31; an abutment spring 33 is fixedly connected to the surface of the lower gear ring 30, and one end of the abutment spring 33 is fixedly connected to the surface of the abutment portion 702.

[0045] In this embodiment, the upper gear ring 29 and the opposite side of the upper gear ring 29 are fixedly connected with a tooth block 31, the tooth block 31 is arranged at an angle, and a magnet sheet 32 ​​is also fixedly connected to the tooth block 31. When the rotating member 17 rotates, the lower gear ring 30 and the upper gear ring 29 rotate due to magnetic force, and the two arc-shaped clamping plates 6 on the placement plate 4 are moved toward each other through the transmission component, thereby fixing the culture dish.

[0046] Specifically, the transmission component includes a screw rod 34 and a transmission bevel gear 35. The screw rod 34 is movably connected to the placement plate 4. The arc-shaped clamping plate 6 is threadedly sleeved on the surface of the screw rod 34. The transmission bevel gear 35 is fixedly sleeved on the surface of the screw rod 34. The bottom of the placement plate 4 is also movably connected with an active bevel gear 36 and a pressure plate 37 through a connecting shaft. The active bevel gear 36 is meshed with the transmission bevel gear 35, and the opposite sides of the pressure plate 37 and the upper gear ring 29 are fixedly connected with extrusion teeth 38.

[0047] In this embodiment, the transmission component includes an active bevel gear 36 and a pressure plate 37 movably connected to the bottom of the placement plate 4 through a connecting shaft. A plurality of extrusion teeth 38 are evenly fixed in an array on the pressure plate 37. When the rotating member 17 moves upward, the upper gear ring 29 docks with the extrusion teeth 38 between the pressure plate 37. Therefore, when the rotating member 17 rotates, the active bevel gear 36 can drive the two transmission bevel gears 35 meshing with it to rotate through the connecting shaft, thereby realizing the rotation of the screw rod 34, and then the arc-shaped clamping plates 6 can move toward each other to fix the culture dish.

[0048] Specifically, an electromagnet 39 is fixedly connected to the position of the support frame 3 corresponding to the placement plate 4, and a brake member 40 is movably connected to the surface of the placement plate 4. A magnet block 41 is fixedly connected to the surface of the brake member 40. When dyeing is required, after the laser receiver 11 receives the optical signal from the laser transmitter 10, the electromagnet 39 is energized to separate the brake member 40 from the placement plate 4 by adsorbing the magnet block 41.

[0049] In this embodiment, when dyeing is not required, the electromagnet 39 remains energized, and the current thereon can cause the magnet block 41 to be subjected to a repulsive force, thereby causing it to drive the brake member 40 to squeeze the placement plate 4 to prevent the placement plate 4 from rotating. When dyeing is required, a reverse current is passed through the electromagnet 39, and the rotating member 17 is disengaged from the placement plate 4, so that the rotation can be achieved under the action of the rotating frame.

[0050] When in use, the culture dish containing the cell fluid is placed on the placement tray 4. Each placement tray 4 is provided with two arc-shaped clamping plates 6. The spacing between the two arc-shaped clamping plates 6 is wide enough to place a culture dish of conventional maximum size. The staining rack 2 is fixed to the support frame 3 by screws, and the pre-prepared stain is injected into it.

[0051] After the culture dish is placed on the placement tray 4, the driving motor 8 is started. Under the action of the driving motor 8, the rotating shaft 9 is driven to rotate, and the rotating shaft 9 drives the support frame 3 to rotate, so that the plurality of placement trays 4 thereon can be driven to rotate simultaneously. In this process, the electromagnet 39 is kept energized, and the current on the electromagnet 39 can cause the magnet block 41 to be subjected to a repulsive force, so that it can drive the brake member 40 to squeeze the placement tray 4 to prevent the placement tray 4 from rotating. A rotating frame is fixedly connected to the bottom of the placement tray 4, and a rotating member 17 is connected to the interior of the rotating frame. The rotating member 17 includes an intermediate portion 701, which is integrally formed in the middle. The abutment portion 702 at the top of the middle portion 701 and the adjusting portion 703 integrally formed at the bottom of the middle portion 701, under the action of the support frame 3, the bottom of the adjusting portion 703 will contact the surface of the rising arc plate 24, so that it will be squeezed and move upward under the action of the rising arc plate 24. At this time, the connecting spring 21 is stretched, and after the rotating member 17 rises to the highest point, the outer teeth 19 on the middle portion 701 are disengaged from the inner teeth 20 inside the circular tube portion 501, and one end of the connecting spring 21 is connected to the inside of the circular tube portion 501 through a limit bearing, which will not cause any influence when the rotating member 17 rotates.

[0052] When unlocking is not required, the outer tooth plate 25 will not contact the teeth on the adjusting portion 703 under the action of the screw 26, so that it will not rotate. Then the adjusting portion 703 contacts the inner tooth plate 28 and meshes with the teeth thereon. The adjusting portion 703 drives the intermediate portion 701 and the abutting portion 702 thereon to rotate. The abutting portion 702 is also movably connected with an upper tooth ring 29, and a plurality of extrusion teeth are evenly arrayed on the top of the upper tooth ring 29. A lower tooth ring 30 is also slidably sleeved on the abutting portion 702. Specifically, the lower tooth ring 30 is 0, the inner connecting block is connected to the inner side wall of the abutment portion 702, an abutment spring 33 is fixedly connected between the lower gear ring 30 and the abutment portion 702, the upper gear ring 29 and the opposite side of the upper gear ring 29 are fixedly connected with tooth blocks 31, the tooth blocks 31 are arranged obliquely, and a magnet sheet 32 ​​is fixedly connected to the tooth blocks 31. When the rotating member 17 rotates, the lower gear ring 30 and the upper gear ring 29 rotate due to magnetic force, and the two arc-shaped clamping plates 6 on the placement plate 4 move toward each other through the transmission component, so as to fix the culture dish.

[0053] The transmission component includes an active bevel gear 36 and a pressure plate 37 movably connected to the bottom of the placement plate 4 through a connecting shaft. A plurality of extrusion teeth 38 are evenly fixed on the pressure plate 37. When the rotating member 17 moves upward, the upper gear ring 29 docks with the extrusion teeth 38 between the pressure plate 37. Therefore, when the rotating member 17 rotates, the active bevel gear 36 drives the two transmission bevel gears 35 meshing with it to rotate through the connecting shaft, thereby realizing the rotation of the screw rod 34, and then the arc-shaped clamping plates 6 can move toward each other to fix the culture dish. Inclined surfaces are provided on both sides of the rising arc plate 24 to facilitate the rising and falling of the rotating member 17. When the rotating member 17 is out of contact with the rising arc plate 24, the rotating member 17 automatically resets downward under the action of the connecting spring 21, and the outer teeth 19 on the middle part 701 are again in contact and meshed with the inner teeth 20 inside the circular tube part 501, so as to limit the rotating member 17 and prevent shaking.

[0054] When one of the placement trays 4 moves to the dyeing position, the laser emitted by the laser transmitter 10 on the dye will be received by the laser receiver 11, and the received light signal will be transmitted to the processor. After processing by the processor, the driving motor 8 is powered off and self-locked through the controller, so that the support frame 3 stops rotating. At this time, the circular tube portion 501 on the rotating member 17 contacts the transmission member, and the teeth on the circular tube portion 501 can mesh with the teeth on the transmission member 7. Then the driving motor 12 is started, driving the threaded rod 13 and the transmission pulley 18 on its output shaft to rotate. The rotation of the threaded rod 13 can cause the piston 14 on it to move upward, so that the dye inside the dyeing frame 2 can be pushed out of the dyeing tube. At the same time, the transmission pulley 18 rotates the rotating member 17 through the belt, which can drive the circular tube portion 501 to rotate, and then the placement tray 4 can be rotated through the support portion 502 on the circular tube portion 501, and then the culture dish can be rotated, so that the dye can be evenly dripped into the culture dish.

[0055] The filling of the dye is timed by a timer. After the timing is over, the drive motor 12 is powered off and the drive motor 8 is restarted. Then the support frame 3 continues to rotate, and the electromagnet 39 is supplied with reverse current to repel the magnet block 41, so that the brake member 40 can fix the placement plate 4. Then the adjustment part 703 will contact the vibration-assisting plate 22 fixed inside the support bottom cover 1. The vibration-assisting plate 22 is provided with an inclined surface. Under the action of the inclined surface, the adjustment part 703 drives the entire rotating part 17 to move downward. At this time, the connecting spring 21 is compressed to the minimum. A plurality of baffles 23 are evenly arranged in an array on the adjustment part. At the same time, a plurality of vibration points are fixedly connected to the vibration-assisting plate 22. The baffles 23 contact the vibration points and vibrate. According to the density of the baffles 23 and the density of the vibration points, high-frequency and low-amplitude vibrations can be achieved, so that the rotating frame is vibrated through the rotating member 17, and then the placement plate 4 is rotated. The components of the cell fluid and the dye can be mixed, which is convenient for rapid dyeing.

[0056] Since dyeing may take a long time, the dyeing rack 2 can be removed after all the culture dishes are filled with dye. Under the action of the drive motor 12, the support frame 3 continues to rotate. After the brake member 40 is out of contact with the vibration-assisting plate 22, it will contact the inner tooth plate 28 again. Under the action of the inner tooth plate 28, the rotating member 17 rotates again to achieve the opposite movement of the arc-shaped clamping plate 6. This design makes it possible for the arc-shaped clamping plate 6 to loosen when the vibration-assisting plate 22 rotates the rotating member 17, resulting in unstable clamping or even offset. However, continuous rotation of the rotating member 17 may cause the arc-shaped clamping plate 6 to continue to pressurize the culture dish, causing the culture dish to rupture or even the support frame 3 to be unable to rotate. Therefore, the lower tooth ring 30 and the upper tooth ring 29 can move relative to each other.

[0057] As mentioned above, the upper toothed ring 29 is connected to the lower toothed ring 30 by the magnet sheet 32, and the upper toothed ring 29 is movably connected to the abutment portion 702, and the lower toothed ring 30 is slidably connected to the abutment portion 702. When the culture dish causes the arc-shaped clamping plate 6 to rotate for lunch, the extrusion force will be concentrated on the extrusion teeth 38 between the upper toothed ring 29 and the pressure plate 37, and the upper toothed ring 29 and the lower toothed ring 30 are connected by magnetic force. Therefore, when the upper toothed ring 29 cannot rotate and the rotating part 17 at the bottom continues to rotate, the lower toothed ring 30 is pressed and moves downward, and under the action of the abutment spring 33, it reciprocates up and down to realize the continuous rotation of the rotating part 17, and the arc-shaped clamping plate 6 will not move, thereby protecting the culture dish. This design is also conducive to clamping culture dishes of different sizes.

[0058] With the help of the vibration-assisting plate 22, the cells inside the cell fluid are quickly stained with the dye. After the staining is completed, it is detected by an electron microscope at the detection position. Finally, the outer tooth plate 25 moves toward the direction close to the inside of the supporting bottom cover 1 through the screw 26 to achieve the contact between the outer tooth plate 25 and the adjustment part 703. Under the action of the outer tooth plate 25, the adjustment part 703 is reversed, so that the arc-shaped clamping plate 6 can be moved away from each other through the rotating component, and the contact with the culture dish is broken, so that the culture dish can be disassembled.

[0059] Through the above scheme, the culture dish can be automatically fixed and vibrated, and dye can be added to the cell fluid, which is convenient for rapid detection of cells and shortening of dyeing time, thereby shortening the detection cycle.
