[0029] A centrifugal staining and sealing device, see Figures 1 to 3 , comprising a workbench 1, on which is disposed:

[0030] A centrifugal staining device, used for centrifugal separation and staining of a cell smear;

[0031] The sealing device is used to dismantle the cell smear after staining the centrifugal device, drip glue and seal the slide with a cover glass in sequence.

[0032] In this embodiment, the cell smear is placed in a centrifugal staining device to perform centrifugation and staining operations. After the centrifugation and staining are completed, the stained cell smear is removed, glue is dripped, and coverslips are used to seal the slides in sequence using a sealing device, replacing traditional manual operations and reducing the burden of manual operations to ensure that the sample can be correctly separated and sealed, thereby achieving standardized cell preparation.

[0033] Specifically, the centrifugal device includes a centrifuge 11 disposed on a workbench 1 and a staining structure operating above the centrifuge 11 , and the staining structure stains the cell smear during the interval time when the centrifuge 11 is operating.

[0034] The centrifuge 11 centrifuges the cell smear. During the interval of the centrifuge 11, the staining structure intervenes to inject the corresponding stain into the cell smear in the centrifuge 11, thereby completing the double process of centrifugation and staining.

[0035] Specifically, the staining structure includes a support frame 12, a multi-axis robotic arm 13 installed on the support frame 12, a support platform 14 arranged at the end of the multi-axis robotic arm 13, and a staining outflow mechanism 15 installed on the support platform 14 for selectively selecting staining droplets for cell smears. The staining outflow mechanism 15 is connected to an integrated confluence mechanism 16 for integrating and converging multiple staining liquids. A control module for controlling the cutoff or establishing a connection relationship between the staining outflow mechanism 15 and the integrated confluence mechanism 16 is arranged between the staining outflow mechanism 15 and the integrated confluence mechanism 16. The support platform 14 is driven away from and close to the centrifuge 11 by the multi-axis robotic arm 13, and combined with the control of the control module, the cell sample in the cell smear can be selectively stained by droplets.

[0036] The staining process is carried out by connecting the dyeing liquid to the integrated confluence mechanism 16, and converging various dyeing liquids in the integrated confluence mechanism 16 through a water pump, cooperating with the multi-axis robotic arm 13 to drive the support platform 14 away from and close to the centrifuge 11, and under the control of the control module, utilizing the cutoff or connection relationship between the dyeing outflow mechanism 15 and the integrated confluence mechanism 16 to selectively perform drop staining on the cell sample in the cell smear.

[0037] Specifically, the integrated confluence mechanism 16 includes a confluence plate 161 , a liquid inlet channel 162 provided in the confluence plate 161 for the dye liquid to enter, and a liquid outlet channel 163 provided in the confluence plate 161 for the dye liquid to flow out, and one liquid inlet channel 162 is connected to one liquid outlet channel 163 .

[0038] In this embodiment, twelve liquid inlet channels 162 and twelve liquid outlet channels 163 are opened in the confluence plate 161. Each liquid inlet channel 162 and each liquid outlet channel 163 are independently arranged, and one liquid inlet channel 162 is connected to one liquid outlet channel 163, and then the liquid outlet channel 163 is connected to one dyeing tube 151, so as to avoid mutual interference between dyeing liquids and realize the circulation and transportation of dyeing liquids.

[0039] The integrated form of the manifold 161 avoids the connection arrangement of traditional pipelines and the trouble of densely arranging multiple lines.

[0040] Specifically, the dye outflow mechanism 15 includes a plurality of dye tubes 151 connected to the integrated confluence mechanism 16, and each dye tube 151 corresponds to a different dye solution.

[0041] It also includes a plurality of negative pressure pumps 152 installed on the support platform 14 , each negative pressure pump 152 is connected to a corresponding pipette 153 , and the pipette 153 corresponds to the cell smear device one by one.

[0042] In this embodiment, six dyeing tubes 151 are arranged in a set of dyeing outflow mechanisms 15. Each dyeing tube 151 corresponds to a dyeing liquid. The required dyeing liquid can be added autonomously according to the dyeing requirements.

[0043] Since the cell fluid is processed after centrifugation before staining, a layer of impurities floats on the surface of the cell fluid in the centrifuge tube. It is necessary to suck it away to avoid affecting the subsequent staining.

[0044] The pipette 153 of this embodiment is bound together with the dyeing tube 151 and moves with the dyeing tube 151. If dyeing needs to be carried out through the dyeing tube 151, the pipette 153 must be used to absorb waste liquid first, and negative pressure is generated in the pipette 153 through the negative pressure pump 152. Each group of dyeing outflow mechanisms 15 corresponds to a group of pipettes 153.

[0045] Specifically, the control module includes an electrical control box 17 and a plurality of solenoid valves 18 electrically connected to the electrical control box 17 . The solenoid valves 18 are installed on the integrated confluence mechanism 16 . The switches of the solenoid valves 18 are controlled by the electrical control box 17 to cut off or establish communication between the dyeing outflow mechanism 15 and the integrated confluence mechanism 16 .

[0046] In this embodiment, an electric control box 17 controls the solenoid valve 18, and the solenoid valve 18 is used to control the connection between the confluence channel 164 and each liquid inlet channel 162, so as to realize the control of the type selection and directional distribution of the dyeing liquid.

[0047] Specifically, the sealing device includes a gantry support 2 installed on a workbench 1 and a placement fixture 21 sliding on the workbench 1, and the gantry support 2 is provided with a grabbing component 22 for grabbing a cover glass, a glue dripping component 23 for dripping glue on a cell smear, and a removal component 24 for removing a centrifuge tube on a cell smear;

[0048] Cooperating with the sliding of the placement fixture 21, the centrifuge tube on the cell smear apparatus is removed in turn through the removal component 24, the glass slide on the cell smear apparatus is glued through the glue dripping component 23, and the cover glass is grabbed by the grabbing component 22 and covered on the glass slide to complete the sealing operation.

[0049] After centrifugation and staining, the coverslipping process will begin.

[0050] The cell smear devices are placed in the placement fixture 21 in order, and with the sliding of the placement fixture 21, the cell smear devices go through the removal component 24, the glue dripping component 23 and the grabbing component 22 in order to complete the slide sealing operation.

[0051] Specifically, the grabbing assembly 22 includes a suction claw and a first driving member that drives the suction claw to approach and move away from the workbench 1; the glue dripping assembly 23 includes an injector, a second driving member that pushes the injector to drip liquid, and a third driving member that drives the injector to approach and move away from the workbench 1; the removal assembly 24 includes a rotating jaw and a fourth driving member that drives the rotating jaw to approach and move away from the workbench 1.

[0052] The first driving member, the third driving member and the fourth driving member are lifting cylinders, and the second driving member is a propulsion cylinder. The lifting cylinders are used to lift and lower the height of the injector, the suction claw and the rotating clamp, and the injector is controlled by the pushing cylinder to perform a dripping operation.

[0053] In this embodiment, a linear module 25 is provided on the workbench 1 , and the placement fixture 21 is driven to move by the linear module 25 .

[0054] Specifically, a placement station 3 for placing a cell smear is provided on the workbench 1 , and the cell smear is grabbed by the grabbing component 22 or the removing component 24 and moved from the placement fixture 21 to the placement station 3 .

[0055] The sealing device of this embodiment can not only be used for sealing operations, but also for transporting cell smears. The grabbing component 22 or the removal component 24 grabs the cell smear from the placement fixture 21 to the placement station 3, and cooperates with an external manipulator or manual labor to transfer the cell smear that needs centrifugal staining to the centrifugal staining device to complete the transportation operation, which has the function of one thing for multiple uses.

[0056] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
