[0002] Liquid-based thin-layer cytology is a cervical cancer screening technology that is currently used more frequently. It involves placing cervical exfoliated cells into a sampling bottle of cell preservation fluid, and using centrifugation and other methods to make the cells into a thin layer of cells and fix them on a glass slide. This can be completed after staining and sealing. This cervical cancer screening method has a series of advantages such as favorable prices, accurate results, and fast detection time. After the preparation chamber is centrifuged, the upper layer of waste liquid needs to be cleaned. The traditional way is to use a flipping mechanism to flip the preparation chamber as a whole and dump out the waste liquid. This method requires an additional flipping mechanism, which is costly, and requires the addition of a transfer device to move the preparation chamber that has completed centrifugation to the flipping station. This not only increases costs, but also increases the space occupied by the equipment. Utility Model Content

DETAILED DESCRIPTION

[0020] like Figure 1-8 In the invention, a waste liquid cleaning structure of a film making chamber is provided, comprising a movable pipetting device 5, the pipetting device 5 comprises a pipette 501, and also comprises a rotatable second turntable 3, a plurality of film making chamber placement grooves 302 are circumferentially arranged on the second turntable 3, a rotatable film making chamber shelf plate 303 is arranged at the film making chamber placement grooves 302, the film making chamber shelf plate 303 is used to place the film making chamber, the pipetting device 5 is provided with a connecting hanger 6, a magnetic block part 601 is arranged at the lower end of the connecting hanger 6, the magnetic block part 601 absorbs one end of the film making chamber shelf plate 303 to tilt the film making chamber, and the pipette 501 is inserted into the film making chamber injection cylinder to suck out the waste liquid.

[0021] In the preferred embodiment, a bottom frame 1 is further included, and the bottom frame 1 includes a bottom plate 101 and an upper plate 102. A second rotating motor 301 is provided in the center of the upper plate 102, and the second rotating motor 301 drives the second turntable 3 to rotate. A liquid discharge head 103 is provided on the upper plate 102, and the liquid discharge head 103 is aligned with the film making chamber.

[0022] A first turntable 2 and a second turntable 3 are coaxially arranged and rotatable on the bottom frame 1. The first turntable 2 is provided with a plurality of sampling bottle placement holes 202 along the circumference, and the sampling bottle placement holes 202 are used to place sampling bottles. The second turntable 3 is provided with a plurality of film making chamber placement grooves 302 along the circumference, and the film making chamber placement grooves 302 are used to place the film making chamber.

[0023] The number of the sampling bottle placement holes 202 and the film making chamber placement slots 302 is equal and evenly distributed along the circumferential direction. On the radial line, each sampling bottle corresponds to a film making chamber.

[0024] A first rotating motor 201 is disposed on the bottom plate 101 , and the first rotating motor 201 drives the first rotating disk 2 to rotate.

[0025] The liquid outlet head 103 can be connected to the external cleaning liquid. After the pipette 501 sucks out the waste liquid in the injection cylinder of the film making chamber, the liquid outlet head 103 injects the cleaning liquid into the injection cylinder, and the pipette 501 sucks away the cleaning liquid inside the injection cylinder again, so that the waste liquid is cleaned more thoroughly.

[0026] The pipetting device 5 originally exists as a mechanism for transferring liquid from the sampling bottle to the film making chamber. A pipeline is provided at the upper end of the pipette 501, which is connected to the external air system and the control valve. Negative pressure can be connected to suction, and positive pressure can be connected to discharge liquid.

[0027] In the preferred embodiment, a multi-axis moving mechanism 4 is provided on the bottom frame 1, and the multi-axis moving mechanism 4 includes a first linear module 401. A second linear module 402 is provided on the sliding plate of the first linear module 401. The sliding plate of the second linear module 402 is connected to the pipetting device 5. The first linear module 401 and the second linear module 402 are arranged vertically. A waste bucket 7 is also provided on one side of the bottom frame 1. The first linear module 401 drives the pipetting device 5 to move above the waste bucket 7 to discharge waste liquid.

[0028] The main structure of the linear module is a screw slider mechanism driven by a servo motor.

[0029] The film-making chamber tilts along with the tilt of the film-making chamber shelf plate 303, so that the pipette 501 can absorb the waste liquid accumulated in the corner of the film-making chamber injection cylinder, and the waste liquid is cleaned more thoroughly.

[0030] In the preferred embodiment, a slot 310 is provided at the film making chamber placement groove 302, and a connecting block 306 is provided in the slot 310. Shelf plate rotating shafts 304 are provided on both sides of the film making chamber shelf plate 303. The shelf plate rotating shafts 304 are rotatably connected to the connecting block 306. A stop pin 307 is also provided at one end of the connecting block 306. U-shaped bayonet holes 308 are provided on both sides of the film making chamber shelf plate 303, and the stop pin 307 is stuck in the U-shaped bayonet hole 308.

[0031] The U-shaped bayonet 308 is located at the other end of the adsorption end, with the opening facing downward. When the magnetic block part 601 adsorbs the end of the film-making chamber shelf 303, the bottom end of the U-shaped bayonet 308 abuts against the stop pin 307 to limit the inclination angle of the film-making chamber shelf 303 to a fixed angle.

[0032] In the preferred embodiment, the connecting hanger 6 includes a fork-shaped frame 602, the open end of the fork-shaped frame 602 is connected to the pipetting device 5, a suspension rod 603 is provided at the lower end of the fork-shaped frame 602, a cross plate 604 is connected to the lower end of the suspension rod 603, and the magnetic block part 601 is arranged on both sides of the lower end of the cross plate 604.

[0033] An arc groove 309 is provided in the middle of the film-making chamber shelf plate 303, which matches the convex arc shape of the lower end of the film-making chamber. After the film-making chamber is inserted into the film-making chamber shelf plate 303, the film-making chamber naturally tilts due to the downward extension 305 provided at the rear end of the film-making chamber shelf plate 303. The lower end of the downward extension 305 is provided with a threaded hole 311, and the center of gravity is adjusted by adjusting the number and screwing depth of the bolts 312 to adjust the inclination of the lower film-making chamber during centrifugation. During centrifugation, the film-making chamber shelf plate 303 is always at the lower side and the outer side, and the film-making chamber is clamped by the arc groove 309, so it will not fall out.

[0034] Under the premise of this structural design, the two side vertical edges of the film making chamber shelf plate 303 are the adsorption positions of the magnetic block part 601, so the connecting hanger 6 needs to be designed with an avoidance structure, and the fork-shaped frame 602 is used to prevent the connecting hanger 6 from interfering with the fixed part of the second linear module 402 when it moves up and down with the pipetting device 5. At the same time, by installing the magnetic block part 601 at both ends of the horizontal plate 604, it is ensured that the magnetic block part 601 is aligned with the two side vertical edges of the film making chamber shelf plate 303.

[0035] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
