Cancer cell sorting and detecting device for specific binding breast cancer cell research and development

[0004] However, in actual use, the device needs to adjust the concentration of the sample liquid through the cooperation of multiple components. More sample liquid adheres to the inner ...

Further, the bottom outer wall of baffle plate 29 is fixedly connected with bristle, and the end of bristle away from baffle plate 29 contacts with the bottom inner wall of sorting tank 9, after the sorting detection of device to sample solution is completed, people need to When the device is cleaned, people can start the baffle plate 29 of the air pump 6 to rotate again, and the bottom inner wall of the sorting tank 9 can be cleaned by the rotation of the baffle plate 29 and the bristles, thereby improving the cleaning effect of the device.

Further, the detection assembly includes a detection plate 20 fixedly connected to the inner walls of the four sides of the housing 11, the detection plate 20 is located below the second mounting plate 19, the top of the detection plate 20 is provided with a detection groove 21, and the detection groove 21 is passed through the detection plate 20 Rapid detection of cancer cells in a sample solution is possible.

Further, the four side inner walls of the housing 11 are all fixedly connected with the second mounting plate 19, the top outer wall of the second mounting plate 19 is fixedly connected with the shielding plate 18, and the top of the second mounting plate 19 is provided with a drain tank 17. The drain tank 17 and the through hole 15 are located on the same vertical plane, and the shielding plate 18 provided at the same time can shield external signals, which can ensure that the sample solution is not interfered by external electromagnetic waves during the subsequent detection process, and improve detection accuracy.

Further, the positioning assembly includes fixed ears 2 fixedly connected to the outer walls of the four sides of the cover plate 1 and the housing 11, and the top of the outer walls of the four sides of the outer walls of the housing 11 is provided with threaded holes, located on the four sides of the cover plate 1 The top of the fixed ear 2 on the outer wall is provided with a jack, and the inner wall of the threaded hole is threaded with a fixed screw 3, and one end of the fixed screw 3 passes through the inside of the jack, and forms a threaded connection between the fixed screw 3 and the fixed ear 2. The tightness of the connection between the cover plate 1 and the casing 11 can be effectively ensured.

Further, the pressurized assembly includes a fixed seat 5 fixedly connected to the top outer wall of the cover plate 1, the top outer wall of the fixed seat 5 is fixedly connected with an air pump 6, and one side outer wall of the air pump 6 is plugged with a connecting pipe 4, and the connecting pipe One end of 4 communicates with the liquid inlet pipe 13, and the air pressure inside the sorting assembly can be adjusted by starting the air pump 6, thereby improving the sorting efficiency of the sample solution by the sorting assembly.

Further, the sorting assembly includes the first mounting plate 16 fixedly connected to the inner wall of the housing 11, the top outer wall of the first mounting plate 16 is fixedly connected with the sorting groove 9, and the cross section of the sorting groove 9 is a spiral , the liquid inlet pipe 13 is located directly above one end of the sorting tank 9, and one end of the sorting tank 9 is fixedly connected with a liquid separating tank 8 and a waste liquid tank 14, and the bottom inner wall of the waste liquid tank 14 is provided with a drain hole 28, and the sorting tank The inside of 9 is provided with a turbulence component. After the sample solution is added to the inside of the sorting tank 9, the cancer cells and white blood cells inside the sample solution are subjected to different sizes of inertial force and Dean force in the spiral sorting tank 9, so that Cancer cells and leukocytes are separated at one end of the spiral sorting tank 9. During this process, the cancer cell solution enters the inside of the liquid separating tank 8, while the white blood cell solution enters the waste liquid tank 14 on the other side and is discharged. The sorting tank 9 separates cancer cells and white blood cells, and not only has a simple structure, but also does not require human intervention during the sorting process, and the sorting...
