Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cell separation, in particular to a high-efficiency single cell separator. Background Art
[0002] A single-cell isolator is an instrument specifically designed to accurately and rapidly isolate single cells from biological samples. This device is crucial in the fields of biotechnology, medical research, drug development, and clinical diagnostics because it can provide high-quality single-cell samples for further analysis and research.
[0003] In daily life, single cells usually need to be separated before they can be tested and detected. However, existing single-cell separation methods usually use micromanipulation to separate single cells. The solution containing the single cells must be centrifuged beforehand. However, cell centrifugation usually requires a one-to-one operation to complete, which is complicated and not conducive to the rapid completion of the single-cell solution separation operation, affecting daily work efficiency.
[0004] After searching, the patent with application number CN2020230097153 discloses a rapid single-cell separation device, including a workbench, a placement table, a mounting seat and a mounting frame, wherein a separation frame is provided inside the mounting frame, the bottom of the separation frame is fixedly connected to a rotating rod, one end of the rotating rod is fixedly connected to a motor assembly, the surface of the separation frame is provided with a fixed groove, and the interior of the fixed groove is movably connected to a separation tube. In the present utility model, the separation frame, the separation tube and the separation net provided can realize rapid centrifugal separation of different single-cell organisms in different single-cell solutions in multiple separation tubes. When in use, the staff first takes out the separation tube placed in the placement hole on the placement table, pours the single-cell solution into the separation net in the separation tube, and then places the separation tube containing the single-cell solution in the fixed groove in the separation frame, and uses the fixed clamp on the separation tube to quickly clamp the separation tube.
[0005] This structure performs synchronous cell separation by installing multiple groups of separation tubes on a separation rack. However, the structure lacks a temperature control device. Cell separation requires a certain low temperature condition, and different single-cell solutions require different temperature environments. In actual operation, multiple operations are required, which affects the separation efficiency. At the same time, the cell solution needs to be shaken before placement to prevent clumping. Shaking multiple groups of test tubes in sequence increases the workload of personnel and reduces the separation efficiency. Utility Model Content

A separation test tube 9 is installed on the top of the carrying cylinder 8. The bottom end of the separation test tube 9 is located inside the carrying cylinder 8. A solenoid valve 10 is installed at the bottom of the carrying cylinder 8. A temperature sensor 11 is fixedly installed on the inner wall of the carrying cylinder 8. A refrigerator 12 is installed on the right side of the thermal insulation shell 3. A processor 13 and a signal transmission module are integrated inside the thermal insulation shell 3. The signal transmission module, refrigerator 12, solenoid valve 10 and temperature sensor 11 are all connected to the processor 13 signal. An auxiliary component 14 is provided inside the thermal insulation shell 3.
[0024] The auxiliary component 14 includes a synchronous motor 1401, which is fixedly installed at the bottom of the centrifugal seat 5. A synchronous gear disc 1402 is fixedly connected to the output shaft of the synchronous motor 1401, and an outer gear ring 1403 is fixedly connected to the outer side of the supporting tube 8. The outer gear ring 1403 is located on the outer side of the synchronous gear disc 1402 and engages with the synchronous gear disc 1402.
[0025] A metal ring 17 is fixedly connected to the outside of the separation tube 9 , and a magnetic ring 18 is connected to the top of the carrying cylinder 8 . The metal ring 17 is located on the top of the magnetic ring 18 and is magnetically connected to the magnetic ring 18 .
[0026] A heat-insulating cover plate 19 is hinged on the top of the heat-insulating outer shell 3 , and a handle is connected to the top of the heat-insulating cover plate 19 .
[0027] When single cells need to be separated, the test tube rack 2 can be used to place the test tubes. After taking out the separation test tube 9, the single cell solution is poured into the separation test tube 9. There is a separation net inside the separation test tube 9. The user then inserts the separation test tube 9 into the through slot 7 so that its bottom end enters the interior of the carrying tube 8. During the downward movement, the metal ring 17 on the side contacts the magnetic ring 18 and is adsorbed on its top, thereby completing the limitation of the separation test tube 9. The user then inserts the separation test tube 9 into different carrying tubes 8 in turn. The user then closes the top insulation cover 19 to make the insulation shell 3 sealed. The user then controls the operation of the auxiliary component 14, and the synchronous motor 1401 drives the synchronous gear disc 1402 fixed to it to rotate slowly. The outer gear ring 1403 evenly distributed on the side begins to rotate accordingly. Multiple groups of carrying tubes 8 drive multiple groups of separation test tubes 9 to rotate, so that the inner The single cell solution is shaken to avoid cell clumping.

The processor 13 changes the opening and closing state of the solenoid valve 10 in real time to keep the internal temperature of the carrier tube 8 within the set range. The centrifugal motor 6 drives the rotating frame 4 to rotate, and the centrifugal seat 5 rotates accordingly, cooperating with the auxiliary component 14 to achieve rapid separation of the single cell solution, isolating the single cell in the separation net. When the separation is completed, the user controls the electrical appliance to stop and lifts the thermal insulation cover 19 to take out the separation tube 9.
[0028] In the present invention, the separation test tubes 9 are placed inside the carrier tube 8, the air intake rate is controlled by the solenoid valve 10, and the temperature sensor 11 is used to realize automatic temperature control, thereby realizing the simultaneous separation operation of single-cell solutions with different temperature requirements, improving the separation efficiency and reducing the number of human operation steps. At the same time, by setting the auxiliary component 14, multiple groups of separation test tubes 9 can be rotated slowly before centrifugation, so that the single-cell solution is evenly dispersed to avoid the formation of clumps that affect subsequent separation.
[0029] See also Figure 1 , wherein: a control panel 15 is fixedly mounted on the top of the mounting base 1 , and the centrifugal motor 6 , the refrigerator 12 , the solenoid valve 10 and the auxiliary components 14 are all electrically connected to the control panel 15 .
[0030] In the present invention, the setting of the control panel 15 allows users to operate the device more simply and quickly, thereby reducing the steps required by the users and improving the efficiency of single cell separation.
[0031] See also Figure 1 and 4, wherein: a flashing light 16 is installed on the outside of the heat-insulating shell 3 , and the flashing light 16 is connected to the processor 13 signal.
