Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.

[0033] As shown in the drawings, Figures 1 to 4 The cell liquid sample transfer device in an embodiment of the present application comprises a bottom plate 1, a conveying mechanism 2, a transfer mechanism 3 and a waste liquid cylinder 4.

[0034] As shown in the drawings, Figures 1 to 4 The conveying mechanism 2 is installed on the bottom plate 1, and the conveying mechanism 2 is used for conveying a cell liquid sample tube.

[0035] The conveying mechanism 2 comprises a motor 201, and the motor 201 is used for driving a rotating disc 202 to rotate. The motor 201 is connected with the rotating disc 202 at the output end, and a plurality of fixed buckles 203 are installed on the rotating disc 202. The fixed buckles 203 are installed with sample tubes, and the cell liquid sample tubes after detection are placed on the fixed buckles 203.

[0036] As shown in the drawings, Figures 1 to 4 The transfer mechanism 3 is installed on the bottom plate 1 and is arranged on one side of the conveying mechanism 2, and the transfer mechanism 3 is used for transferring the cell liquid in the sample tube.

[0037] The transfer mechanism 3 comprises a mounting plate 301, and a motor cylinder 302 is installed on the mounting plate 301. The motor cylinder 302 is used for driving a connecting plate 303 to lift, and then can drive a connecting end 304 and a hollow needle 305 to lift. The motor cylinder 302 is connected with the connecting plate 303 at the free end, and the connecting plate 303 is used for installing the hollow needle 305 and a dual-purpose pump 306.

[0038] In addition, the connecting plate 303 is installed with the connecting end 304, and the connecting end 304 is used for connecting the hollow needle 305.

[0039] Preferably, the hollow needle 305 can be installed on the connecting end 304 in a threaded connection manner, so as to replace the hollow needle 305.

[0040] Specifically, the connecting end 304 is connected with a hollow needle 305, one end of the hollow needle 305 is arranged in the sample tube. Before the cell liquid is detected, the hollow needle 305 can be inserted into the sample tube, and then the cell liquid in the sample tube can be blown by the two-purpose pump 306, so that the cell liquid is uniformly mixed.

[0041] After the cell liquid is detected, the hollow needle 305 can be inserted into the sample tube again, so that the cell waste liquid in the sample tube is sucked into the waste liquid cylinder 4 by the hollow needle 305, and the transfer of the cell waste liquid is completed.

[0042] As shown in the figure, the connecting plate 303 is installed with a pipetting mechanism, which is used for pipetting operation of the cell liquid in the sample tube. Figures 1 to 4

[0043] The pipetting mechanism includes a two-purpose pump 306, which is installed on the connecting plate 303, and the two-purpose pump 306 is connected with a connecting pipe 307. The two-purpose pump 306 is used for blowing gas into the sample tube, so that the cell liquid is uniformly mixed, and is used for sucking the gas in the waste liquid cylinder 4, so that the waste liquid cylinder 4 becomes a negative pressure state, so as to suck the cell liquid in the sample tube.

[0044] Preferably, the two-purpose pump 306 is a gas filling / sucking two-purpose pump, which can blow gas into the sample tube, and can also suck the gas in the waste liquid cylinder 4, so that the waste liquid cylinder 4 becomes a negative pressure state, so as to suck the cell liquid in the sample tube.

[0045] In addition, the connecting pipe 307 is installed with a three-way pipe 308, and the three-way pipe 308 is connected with a first branch pipe 309 between the connecting end 304. Before the cell liquid is detected, the two-purpose pump 306 is controlled to blow gas, the electromagnetic valve on the first branch pipe 309 is opened, and the electromagnetic valves on the second branch pipe 310 and the infusion pipe 311 are closed, so that the two-purpose pump 306 can blow gas into the cell liquid in the sample tube through the connecting pipe 307, the three-way pipe 308, the first branch pipe 309 and the hollow needle 305, so as to uniformly mix the cell liquid.

[0046] Specifically, the three-way pipe 308 is connected with the second branch pipe 310 between the waste liquid cylinder 4, and the connecting end 304 is connected with the infusion pipe 311 between the waste liquid cylinder 4. When the cell waste liquid in the sample tube needs to be discharged, the two-purpose pump 306 is controlled to suck gas, the electromagnetic valve on the first branch pipe 309 is closed, and the electromagnetic valves on the second branch pipe 310 and the infusion pipe 311 are opened, so that the two-purpose pump 306 makes the waste liquid cylinder 4 become a negative pressure state through the connecting pipe 307, the three-way pipe 308 and the second branch pipe 310, and the waste liquid cylinder 4 makes the sample tube form a negative pressure state through the infusion pipe 311, so that the cell waste liquid in the sample tube can enter into the waste liquid cylinder 4 through the hollow needle 305, the connecting end 304 and the infusion pipe 311, and the transfer of the cell waste liquid is realized.

[0047] ​In addition, solenoid valves are installed on the first branch pipe 309, the second branch pipe 310 and the infusion pipe 311 to control the opening and closing of the first branch pipe 309, the second branch pipe 310 and the infusion pipe 311.

[0048] like Figures 1 to 4 As shown, a stabilizer 312 is mounted on the connecting plate 303, and a stabilizing buckle 313 is bolted to one end of the stabilizer 312. The stabilizer 312 and the stabilizing buckle 313 are provided with corresponding through slots, and one end of the hollow needle 305 passes through the through slot to stabilize the hollow needle 305.

[0049] like Figures 1 to 4 As shown, the waste liquid cylinder 4 is installed on the base plate 1 and located on one side of the conveying mechanism 2. The waste liquid cylinder 4 is connected to the pipetting mechanism. The waste liquid cylinder 4 is used to temporarily store cell fluid for centralized processing.

[0050] The waste liquid cylinder 4 has a graduated groove and a drain pipe on its side wall. A control valve is installed on the drain pipe to facilitate observation of the cell waste liquid volume in the waste liquid cylinder 4 so that it can be discharged in a timely manner through the drain pipe.

[0051] In practical use, place the cell fluid sample tube after testing onto the fixing buckle 203, run the motor 201, and the motor 201 drives the rotating disk 202 and the fixing buckle 203 to rotate, so that the fixing buckle 203 moves directly below the hollow needle 305.

[0052] The electric cylinder 302 is controlled to retract, which drives the connecting plate 303 and the hollow needle 305 to descend, so that one end of the hollow needle 305 can be inserted into the cell fluid of the sample tube and close to the bottom of the sample tube.

[0053] The dual-purpose pump 306 is controlled to draw in air, opening the solenoid valves on the second branch pipe 310 and the infusion pipe 311, and closing the solenoid valve on the first branch pipe 309. The dual-purpose pump 306 evacuates the waste liquid cylinder 4 through the connecting pipe 307, the three-way pipe 308, and the second branch pipe 310, making the waste liquid cylinder 4 a negative pressure state. As the negative pressure inside the waste liquid cylinder 4 gradually increases, the cell fluid in the sample tube can enter the waste liquid cylinder 4 through the hollow needle 305, the connecting end 304, and the infusion pipe 311, thereby realizing the transfer of cell waste fluid.

[0054] When the cell fluid in the sample tube has been completely transferred, the electric cylinder 302 is extended, causing one end of the hollow needle 305 to move out of the sample tube. The motor 201 is then activated, causing the fixing buckle 203 at the next position to move directly below the hollow needle 305. The above operation is repeated to perform the pipetting operation on the next sample tube.

[0055] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims to the figures in which the reference signs are used.

[0056] Furthermore, it should be understood that although the present specification is described in terms of embodiments, not every embodiment according to the present specification needs to exhibit each and every characteristic specified in the present specification. The specification can also be described in terms of a single independent technical solution, but this does not mean that each embodiment only contains one independent technical solution.
