Description

Technical Field

[0001] This utility model relates to the field of pretreatment devices, and in particular to an automatic pretreatment device for secretion samples. Background Technology

[0002] When testing secretions, the sample tubes usually contain a lot of mucus in addition to the original sample preservation solution. Therefore, the pretreatment of such samples requires manual shaking to remove as many exfoliated cells as possible from the mucus. Then, the mixed sample is taken for the next step of testing. When removing mucus from the sample, a digestive solution such as dithiothreitol is usually added to remove the mucus from the sample.

[0003] This step requires manual processing of each sample tube, which takes up a lot of manpower and time. Furthermore, due to mucus and other factors, cells may not be completely shed during manual processing, resulting in a low cell count during testing and thus affecting the quality of the test.

[0004] Therefore, it is necessary to provide a new automated pretreatment device for secretion samples to solve the above-mentioned technical problems. Utility Model Content

[0026] The horizontal swing device includes a rotating component, a base bracket 5, a connecting frame 6, and at least two insert rods 7. The rotating component is fixedly mounted on the base bracket 5, and the at least two insert rods 7 are fixedly connected to the base bracket 5. The insert rods 7 movably pass through the connecting frame 6, which is connected to the vertical vibration device. The rotating component includes a vertical plate 8, a drive motor 9, a swing frame 12, and a rack 14. The vertical plate 8 is fixedly mounted on the base bracket 5, and the drive motor 9 is fixedly mounted on the vertical plate 8. A turntable 10 is fixedly connected to the output end of the drive motor 9, and a pressing rod 11 is fixed near the edge of the turntable 10. The swing frame 12 is rotatably connected to the upright plate 8 at the middle position. The swing frame 12 has a compression hole 13 near the bottom for the compression rod 11 to pass through. The top of the swing frame 12 has a fan-shaped structure and multiple serrations are fixed. The rack 14 is fixed to the bottom of the connecting frame 6 and meshes with the multiple serrations. The turntable 10 is driven to rotate by the drive motor 9. The compression rod 11 compresses the inner wall of the compression hole 13, causing the swing frame 12 to swing. The multiple serrations drive the rack 14 to move back and forth horizontally, thereby causing the connecting frame 6 to move multiple sample tubes back and forth horizontally.

[0027] The vertical vibration device includes a vibration motor 15 and multiple elastic elements. The multiple elastic elements are installed between the connecting frame 6 and the placement frame 1. The vibration motor 15 is fixedly installed on the placement frame 1. The elastic elements include a movable rod 16, a sleeve 17 and a spring 18. The top end of the movable rod 16 is fixedly connected to the placement frame 1, and the bottom end of the sleeve 17 is fixedly connected to the connecting frame 6. The bottom end of the movable rod 16 is movably disposed inside the sleeve 17. The two ends of the spring 18 are fixedly connected to the placement frame 1 and the connecting frame 6. The vibration motor 15 and the elastic elements cause the placement frame 1 and the sample tube to vibrate vertically.

[0028] The lifting component includes an electric cylinder 19 and a guide rod 20. The bottom end of the electric cylinder 19 is fixed to the placement frame 1, and the telescopic end of the electric cylinder 19 is fixedly connected to the pressing plate 4. The bottom end of the guide rod 20 is fixed to the placement frame 1, and the guide rod 20 is movably inserted through the pressing plate 4. The pressing plate 4 is driven to move down by the electric cylinder 19, so that the pressing plate 4 presses on the tube cap of the sample tube, making it difficult for the tube cap to fall off during the oscillation stage.

[0029] The placement frame 1 is fixed with a first limiting plate 21 at both ends, and the connecting frame 6 is fixed with a second limiting plate 22 at both ends. The first limiting plate 21 is threaded with a bolt, and the bolt on the first limiting plate 21 is threaded to the inner wall of the through hole opened in the second limiting plate 22.

The movable frame 2 is reset, and the bolt on the first side plate 23 is rotated to insert it into the second side plate 24. The electric cylinder 19 drives the pressing plate 4 to move down, so that the pressing plate 4 presses on the tube cap of the sample tube, making it difficult for the tube cap to fall off during the vibration stage. Then, the drive motor 9 drives the turntable 10 to rotate, and the extrusion rod 11 extrudes the inner wall of the extrusion hole 13, causing the swing frame 12 to swing. Multiple saw teeth drive the rack 14 to move back and forth horizontally, thereby causing the connecting frame 6 to drive multiple sample tubes to move back and forth horizontally. Through the vibration motor 15 and The elastic element causes the placement rack 1 and the sample tube to vibrate vertically. The placement rack 1 sways in multiple directions under the action of the horizontal swing device and the vertical vibration device, improving the oscillation efficiency. In addition, this device can also oscillate the sample tube vertically and horizontally as needed. When vertical vibration is required, only the vibration motor 15 needs to be started. When horizontal oscillation is required, the bolt on the first limiting plate 21 is rotated so that the upper end of the bolt is threaded into the through hole of the second limiting plate 22. At this time, the distance between the placement rack 1 and the connecting frame 6 remains unchanged, and the drive motor 9 can be started to achieve horizontal vibration. When there is a lot of sample liquid in the sample tube, in order to minimize the sample liquid from contaminating the tube cap, only horizontal vibration can be used, improving the flexibility of the device during use.
