DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7 The utility model provides a technical solution: a membrane-type liquid-based thin-layer cell preparation mechanism, comprising a machine base 1, a machine head 11 is movably connected to the outer surface of the upper end of the machine base 1, a sampling rod 12 is fixedly connected to the outer surface of the lower end of the machine head 11, a turntable 13 is connected to the outer surface of the upper end of the machine base 1 through a motor rotation, a glass slide (existing technology) is fixedly connected to the upper end of the turntable 13 through a suction cup, and a retaining cylinder 14 is placed on the glass slide, the sample is sucked by the machine head 11 and then dripped into the retaining cylinder 14, so that the sample is fully in contact with the surface of the glass slide, and then the turntable 13 rotates to throw the sample liquid out of the retaining cylinder 14 through centrifugal force, the sample on the surface of the glass slide is discharged, and then a staining liquid is dripped to stain the glass slide;

[0027] An integration component 2 is located above the turntable 13, and the baffles 14 placed on the surface of the turntable 13 are centrally separated. After dyeing, all the baffles 14 can be directly removed by the integration component 2, and no longer need to be removed one by one, thus saving time;

[0028] The separation component 3 is located inside the turntable 13 and at the lower end of the integration component 2, and is used to separate the integration component 2 and the turntable 13. The separation component 3 cooperates with the head 11 to quickly separate the retaining cylinder 14 sucked on the glass slide from the glass slide, so that the user can remove the glass slide easily.

[0029] The integration component 2 includes an integration disk 20, a card block is fixedly connected to the lower end of the integration disk 20, a card slot is opened at the upper end of the turntable 13, the card block is located inside the card slot, a socket 21 is opened on the outer surface of the ring of the integration disk 20, the blocking cylinder 14 is inserted inside the socket 21, and the lower end of the blocking cylinder 14 is in contact with the glass slide. Before use, the user inserts the blocking cylinders 14 into the socket 21 one by one, and then aligns the card block with the card slot and lowers it, and then the head 11 controls the sampling rod 12 to press the integration disk 20. While pressing, the turntable 13 rotates, so that the head 11 can better stick the blocking cylinder 14 to the surface of the glass slide (at this time, the sampling rod 12 has not inserted the sampling tube).

[0030] A retaining ring 15 is fixedly connected to the annular outer surface of the retaining cylinder 14, and a retaining groove 22 is formed on the annular inner surface of the socket 21. The retaining groove 22 corresponds to and matches the retaining ring 15, and a blocking block 23 is fixedly connected to the inner surface of the retaining groove 22. Through the design of the retaining ring 15 and the retaining groove 22, the downward pressure of the sampling rod 12 can be better transmitted to the surface of the glass slide, and the blocking block 23 can increase the stability of the retaining ring 15 inside the retaining groove 22.

[0031] The outer surface of the upper end of the integrated disk 20 is provided with a liquid storage chamber 27, and the inner surface of the liquid storage chamber 27 is provided with a transmission groove 28. The end of the transmission groove 28 away from the liquid storage chamber 27 is connected to the socket 21, and a pushing block 281 is slidably connected inside the transmission groove 28, and the end of the pushing block 281 contacts the outer surface of the blocking cylinder 14. A lower pressure plate 26 is slidably connected inside the liquid storage chamber 27, and a spring 29 is fixedly connected between the lower pressure plate 26 and the liquid storage chamber 27. If it is necessary to completely remove the blocking cylinder 14 inside the socket 21, the lower pressure plate 26 is directly pressed, and the lower pressure plate 26 moves downward inside the liquid storage chamber 27 and compresses the spring 29. At this time, the liquid inside the liquid storage chamber 27 flows to the pushing block 281 through the transmission groove 28, and the pushing block 281 is aligned with the blocking cylinder 14 to push the blocking cylinder 14 out of the socket 21, thereby completing the overall removal of the blocking cylinder 14 and saving removal time.

[0032] The separation component 3 includes a separation groove 30, wherein a separation rod 31 is slidably connected to the separation groove 30, a telescopic groove 33 is provided at the center position of the separation rod 31, and a force-bearing rod 32 is slidably connected to the telescopic groove 33. A through groove 25 is provided at the corresponding position of the integration disk 20 and the force-bearing disk, and the force-bearing rod 32 passes through the through groove 25. A spring 26 is fixedly connected to the outer surface of the lower end of the force-bearing rod 32. When the glass slide is stained and the retaining cylinder 14 needs to be removed from the glass slide surface, the sampling rod 12 is driven by the machine head 11 to move above the force-bearing rod 32, and then the force-bearing rod 32 is pressed downward. The force-bearing rod 32 moves downward in the separation groove 30 and compresses the spring 26. At this time, liquid is injected into the separation groove 30, and the downward movement of the force-bearing rod 32 reduces the space inside the separation groove 30. The liquid pushes the separation rod 31 to move upward along the separation groove 30, resists the integration disk 20 and lifts up the integration disk 20, so that the retaining cylinder 14 is separated from the glass slide.

[0033] A guide block 35 is fixedly connected to the annular outer surface of the separation rod 31 , and a guide groove 34 is provided inside the separation groove 30 at a position corresponding to the guide block 35 , so as to increase the stability of the movement of the separation rod 31 inside the separation groove 30 .

[0034] A handle 24 is fixedly connected to the outer surface of the upper end of the integrated disk 20. After the separation component 3 separates the integrated disk 20 from the turntable 13, the user can remove the integrated disk 20 through the handle 24, and at the same time hold the handle 24 and push the lower pressure plate 26 with the knuckles to facilitate the user to remove the retaining cylinder 14, aim at the trash can, and then hold the handle 24 to throw the used retaining cylinder 14 into the trash can. The handle 24 is designed as a segmented structure, which is convenient for the sampling rod 12 to squeeze the force-bearing rod 32.
