For example, the microscopic detection of the smear is the basic method of liquid cytology detection, which is widely used, especially for the diagnosis of various liquid diseases.

[0003] In the prior art, in order to ensure that the smear has high quality standards such as appropriate thickness and uniform distribution, the slide pushing parameters such as the slide pushing angle and the slide pushing speed are set, so that the slide pushing is performed at the set slide pushing parameters.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a perspective assembly structure schematic diagram of an embodiment of the pusher device 10 provided in the application, Figure 2 is Figure 1 a perspective exploded structure schematic diagram of the pusher device 10 in Figure 3 is Figure 2A schematic block diagram of the detection unit 13, the pusher device 10 in the embodiment comprises a conveying unit 11, a sample adding unit 12, the detection unit 13, a processing unit 14 and a pusher unit 15.

[0038] Please refer to Figure 4 and Figure 5 , Figure 4 is Figure 1 A schematic block diagram of the position of an embodiment of the pusher device 10, Figure 5 is Figure 2 A schematic block diagram of the assembly structure of the conveying unit 11 in the embodiment, the conveying unit 11 comprises a conveying driving mechanism 111 and a conveying bearing mechanism 112, the conveying bearing mechanism 112 is used for bearing the slide 110, and the conveying driving mechanism 111 is connected with the conveying bearing mechanism 112 to drive the conveying bearing mechanism 112 to move.

[0039] Among them, the pusher position P1 is arranged along the movement track of the conveying bearing mechanism 112, that is, in actual application, the slide 110 is first borne on the conveying bearing mechanism 112, and then the conveying driving mechanism 111 drives the conveying bearing mechanism 112 to move, so as to convey the slide 110 to the pusher position P1.

[0040] Optionally, in the embodiment, the conveying driving mechanism 111 can be selected from a screw motor, an air cylinder and a belt motor, and the like, and the driving mode is not limited.

[0041] Please refer to Figure 6 , Figure 7 and Figure 8 , Figure 6 is Figure 2 A schematic block diagram of the assembly structure of an embodiment of the detection unit 13 and the bearing unit 16, Figure 7 is Figure 6 A diffusion image of an embodiment of the detection unit 13 collecting samples, Figure 8 is Figure 6 A diffusion image of another embodiment of the detection unit 13 collecting samples, the sample adding unit 12 is used for adding samples to the slide 110, and the detection unit 13 is used for detecting the diffusion parameters of the samples on the slide and generating corresponding detection data.

[0042] Specifically, in the embodiment, the detection unit 13 is used for collecting a diffusion image of the samples on the slide 110, and identifying the diffusion parameters of the samples on the slide 110 according to the diffusion image.

[0043] Optionally, the detection unit 13 can be a camera, a CCD element or a CMOS element, and the like, and the like, and the driving mode is not limited.

[0044] In this embodiment, the diffusion parameter can be at least one of diffusion length, diffusion width, diffusion area, and diffusion rate.

[0045] For example, Figure 7 As shown, when the diffusion image after sample diffusion is complete is circular ( Figure 7 The shaded area in the image represents the diffusion area of ​​the sample. The detection unit 13 acquires all images of the sample diffusion and determines the start image and the completion image of the sample diffusion. Based on the completion image of the sample diffusion, the radius R of the circular diffusion image is determined, and the diffusion area of ​​the sample is calculated. Alternatively, the start time t1 of the sample diffusion is determined based on the start image of the sample diffusion, the end time t2 of the sample diffusion is determined based on the completion image of the sample diffusion, and then the radius R of the circular diffusion image is determined based on the completion image of the sample diffusion. Finally, the diffusion speed v of the sample is determined according to the formula R / (t2-t1)=v.

[0046] For example, Figure 8 As shown, the diffusion image after sample diffusion is completed is linear. Figure 8 The shaded area in the image represents the diffusion area of ​​the sample. The detection unit 13 determines the length K1 or width K2 of the linear diffusion image based on the completed image of the sample diffusion; or, as mentioned above, first determine the start time t1 and the end time t2 of the sample diffusion, then determine the length K1 or width K2 of the linear diffusion image based on the completed image of the sample diffusion, and finally determine the diffusion speed v of the sample according to the formula K / (t2-t1)=v.

[0047] Please refer to the following: Figure 9 and Figure 10 , Figure 9 yes Figure 2 A schematic diagram of the three-dimensional assembly structure of the pusher module 122. Figure 10 yes Figure 9 A schematic diagram of the pushing state of the pusher 120 and the glass slide 110 is shown. The processing unit 14 is communicatively connected to the detection unit 13. The processing unit 14 is used to receive the detection data from the detection unit 13 and determine the pushing parameters based on the detection data. The pushing unit 15 is used to coat the sample onto the glass slide 110 at the pushing position P1 according to the pushing parameters. The diffusion parameters reflect the viscosity of the sample, so that the pushing unit 15 can perform the pushing operation according to the pushing parameters corresponding to the viscosity of the sample. Compared with the prior art, it meets the pushing requirements corresponding to the sample viscosity and ensures the high quality standard of the coating formed by coating the sample onto the glass slide 110.

[0048] The processing unit 14 is configured to determine the viscosity of the sample according to the detection data, and determine the pusher parameter according to the viscosity of the sample. In actual application, the correlation between the diffusion parameter and the viscosity of the sample and the pusher parameter can be stored in the processing unit 14 in advance, for example, as shown in the following table. Taking the diffusion speed of the sample as an example, when the detection unit 13 detects the diffusion speed V of the sample, the processing unit 14 can find the corresponding viscosity N according to the correlation, and then determine the pusher parameter M.

[0049] Diffusion speed V Viscosity Y Pusher parameter M V1 Y1 M1 V2 Y2 M2 V3 Y3 M3

[0050] In actual application, the correlation between the viscosity of the sample and the diffusion parameter can be obtained according to experimental test, or according to experience, or according to the formula Y=kX -1 , where Y represents the viscosity of the sample, k represents the coefficient, and X represents any one of the diffusion length, the diffusion width, the diffusion area and the diffusion speed.

[0051] Further, the pusher unit 15 comprises a first pusher driving mechanism 15a, a second pusher driving mechanism 15b and a pusher assembly 15c. The pusher assembly 15c is configured to mount the pusher 120. The second pusher driving mechanism 15b is connected with the first pusher driving mechanism 15a and the pusher assembly 15c, so that the first pusher driving mechanism 15a drives the pusher 120 to move away from or close to the slide 110 in the first pusher direction A, and the second pusher driving mechanism 15b drives the pusher 120 to spread the sample on the slide 110 in the second pusher direction B. In an embodiment, the first pusher direction A is the vertical direction, and the second pusher direction B is the horizontal direction.

[0052] The pusher parameter can be the pusher angle a as shown in Figure 9 , or the pusher speed of the pusher 120 in the second pusher direction B, or the distance L between the pusher 120 and the slide 110 in the first pusher direction A, or other pusher parameters. Therefore, in actual application, the pusher parameter can be set according to actual needs, which is not limited herein.

[0053] Optionally, in the embodiment, the first pusher driving mechanism 15a and the second pusher driving mechanism 15b are driven by a screw motor. In other embodiments, other driving modes can be used, such as a pneumatic cylinder, which is not limited herein.

[0054] Further referring to Figure 2 , Figure 4 , Figure 6 and Figure 11The pushing device 10 in the embodiment further comprises a carrying unit 16, the conveying carrying mechanism 112 is used for carrying the first slide, the carrying unit 16 comprises a detection carrying mechanism 161, the conveying unit 11 further comprises a first pushing driving mechanism 113 and a first pushing piece 114, the first pushing driving mechanism 113 is connected with the first pushing piece 114, so as to drive the first pushing piece 114 to push the first slide from the conveying carrying mechanism 112 to the detection carrying mechanism 161, the adding unit 12 is used for adding the sample to the first slide, and the detection unit 13 is used for detecting the diffusion parameter of the sample on the first slide and generating corresponding detection data.

[0055] In an embodiment as shown in the figure, Figure 6 The carrying unit 16 further comprises a second pushing driving mechanism 162 and a second pushing piece 163, the second pushing driving mechanism 162 is connected with the second pushing piece 163, so as to drive the second pushing piece 163 to push the first slide after detection from the detection carrying mechanism 161 to the conveying carrying mechanism 112, and the pushing unit 15 is used for applying the sample to the first slide according to the pushing parameter at the pushing position P1.

[0056] Specifically, when the detection unit 13 finishes detecting the sample on the first slide, the second pushing driving mechanism 162 drives the second pushing piece 163 to push the first slide after detection to the conveying carrying mechanism 112, and then the conveying driving mechanism 111 drives the conveying carrying mechanism 112 to move the first slide to the pushing position P1, so that the pushing unit 15 completes the pushing operation on the sample on the first slide according to the pushing parameter, so that the sample on the first slide can be used for detection and pushing operation, and waste of the sample is avoided.

[0057] In another embodiment as shown in the figure, Figure 11 The conveying carrying mechanism 112 is further used for carrying the second slide, the adding unit 12 is further used for adding the sample to the second slide, and the pushing unit 15 is used for applying the sample to the second slide according to the pushing parameter at the pushing position, that is, the detection unit 13 detects the sample on the first slide on the detection carrying mechanism 161, and the pushing unit 15 applies the sample to the second slide, so that the detection operation of the detection unit 13 and the pushing operation of the pushing unit 15 are not performed on the same slide, in this way, during the detection of the detection unit 13, the conveying driving mechanism 111 drives the conveying carrying mechanism 112 to move the second slide to the pushing position P2, without waiting for the detection of the detection unit 13 to be completed, so that the time of the whole process is saved, and the efficiency is improved.

[0058] Optionally, in the other embodiment, the push piece device 10 further comprises a recovery unit 17, which is used for recovering the first slide after detection. In actual application, the second slide can be pushed from the detection bearing mechanism 161 to the recovery unit 17 in the same way as the second push driving mechanism 162 and the second push piece 163.

[0059] Further, the push piece device 10 in the embodiment further comprises a slide storage unit 18, which is used for storing the first slide. A slide receiving position P2 and a slide pushing position P3 are further arranged along the movement track of the conveying bearing mechanism 112. The conveying bearing mechanism 112 is used for receiving the first slide stored in the slide storage unit 18 at the slide receiving position P2. The first push driving mechanism 113 is used for driving the first push piece 114 to push the first slide from the conveying bearing mechanism 112 to the detection bearing mechanism 161 at the slide pushing position P3.

[0060] Specifically, in actual application, the conveying driving mechanism 111 first drives the conveying bearing mechanism 112 to move to the slide receiving position P2, so that the conveying bearing mechanism 112 receives the first slide stored in the slide storage unit 18 at the slide receiving position P2. Then, the conveying driving mechanism 111 drives the conveying bearing mechanism 112 to move to the slide pushing position P3, so that the first slide on the conveying bearing mechanism 112 is transferred to the detection bearing mechanism 161. Finally, the detection and push piece operation are completed.

[0061] Further referring to Figure 2 , Figure 4 and Figure 6 , the bearing unit 16 in the embodiment further comprises a bearing power mechanism 164, which is connected with the detection bearing mechanism 161 to drive the detection bearing mechanism 161 to move. A sample adding position P4 and a first detection position P5 are arranged along the movement track of the detection bearing mechanism 161. The sample adding unit 12 is used for adding the sample to the first slide at the sample adding position P4. The detection unit 13 is used for detecting the diffusion parameter of the sample on the first slide at the first detection position P5, and generating corresponding detection data.

[0062] Specifically, in order to collect a clear and complete diffusion image of the sample, the detection unit 13 is generally installed above the detection bearing mechanism 161. Therefore, in actual application, the bearing power mechanism 164 first drives the detection bearing mechanism 161 to move to the sample adding position P4, so that the sample adding unit 12 adds the sample to the first slide. Then, the bearing power mechanism 164 drives the detection bearing mechanism 161 to move to the first detection position P5, so that the detection unit 13 detects the sample. This way of arranging the sample adding position P4 and the first detection position P5 separately can avoid the interference between the sample adding unit 14 and the detection unit 13.

[0063] Further refer to Figure 2 and Figure 4 The pushing device 10 in the embodiment further comprises a printing unit 19, and a printing position P6 is further arranged along the movement track of the conveying bearing mechanism 112. The printing unit 19 is used for performing slide printing on the first slide at the printing position P6.

[0064] Specifically, after the conveying bearing mechanism 112 receives the first slide stored in the slide storage unit 13 at the slide receiving position P2, the conveying driving mechanism 111 drives the conveying bearing mechanism 112 to move the first slide to the printing position P6, so that the printing unit 19 performs slide printing on the first slide 110.

[0065] Please refer to Figure 12 , Figure 12 is Figure 1 the position schematic diagram of another embodiment of the pushing device 10. In the another embodiment, a second detection position P7 is further arranged along the movement track of the conveying bearing mechanism 112. The detection unit 13 is used for detecting the diffusion parameter of the sample on the slide 110 at the second detection position P7 and generating corresponding detection data. That is, in the another embodiment, after the conveying bearing mechanism 112 receives the slide 110, for example, first receives the slide 110 stored in the slide storage unit 18 at the slide receiving position P2, and after the slide printing is completed at the printing position P6, the conveying driving mechanism 111 drives the conveying bearing mechanism 112 to move the slide 110 to the sample adding position P4, so that the sample adding unit 12 adds the sample on the slide 110, and then the conveying driving mechanism 111 drives the conveying bearing mechanism 112 to move the slide 110 to the second detection position P7, so that the detection unit 13 detects the sample on the slide 110 at the second detection position P7. After the detection is completed, the conveying driving mechanism 111 drives the conveying bearing mechanism 112 to move the slide 110 to the slide pushing position P1, so that the slide pushing unit 15 completes the slide pushing operation at the slide pushing position P1. In this way, the bearing unit 16 in the above embodiment is not needed, and the receiving of the slide 110, the detection of the sample and the slide pushing operation can be completed directly through the conveying unit 11. The structure of the pushing device 10 and the entire flow action are simplified, the cost is reduced, and the time is saved.

[0067] The processing unit is used for controlling at least one of the air outlet angle, the air outlet speed and the air outlet time of the first drying unit according to the first drying parameter.

[0068] For example, when the viscosity of the sample is low according to the diffusion parameter as described above, in order to avoid blowing away the sample cells on the slide 110, the processing unit 14 can control the first drying unit 10a to blow air to the slide 110 in a direction perpendicular to the slide 110, that is, the air outlet angle between the air outlet direction of the first drying unit 10a and the slide 110 is 90°; when the viscosity of the sample is high according to the diffusion parameter, the processing unit 14 can control the air outlet direction of the first drying unit 10a to be inclined relative to the slide 110, for example, control the included angle between the air outlet direction of the first drying unit 10a and the slide 110 to be 30°, which can reduce the air resistance of the first drying unit 10a when blowing air to the slide 110.

[0069] The first drying unit 10a comprises an air supply part 100a, which dries the slide 120 by blowing air to the slide 110. In the embodiment, the drying unit 13 further comprises a heater 100b, which is used to generate drying heat, and then the air supply part 100a blows air to the heater 100b, so that the air blown to the slide 110 is hot air, and the drying efficiency is improved.
