Description

Technical Field

[0001] This utility model relates to the field of cell sorting technology, specifically a cell sorting device. Background Technology

[0002] Cell sorting is a technique for separating specific cell types from a mixed cell population. It is widely used in fields such as biological research, medical diagnosis (e.g., tumor detection), and cell therapy.

[0003] In the cell sorting process, when dealing with a small number of samples, manual shaking is usually performed, mainly by manually picking up the test tubes and shaking them. However, manual shaking is inefficient, time-consuming, labor-intensive, and the shaking effect is not good, so it needs to be improved.

[0004] To address the problems mentioned in the background, those skilled in the art have proposed a cell sorting device. Utility Model Content

[0005] The purpose of this invention is to provide a cell sorting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cell sorting device includes a frame, within which a rotating shaft is rotatably mounted. Two symmetrically distributed rotating frames are mounted on the rotating shaft. A placement frame, U-shaped, is mounted at the end of each rotating frame away from the rotating shaft. The inner wall of each placement frame has a plurality of spaced-apart upper and lower test tube racks, aligned in place. Each upper and lower test tube rack has a corresponding test tube hole for placing test tubes. The device also includes:

[0008] A limiting mechanism is provided on the upper test tube rack to limit the placement of test tubes;

[0009] A transmission mechanism is provided between the frame and the rotating shaft to enable the rotation of the rotating shaft;

[0010] A drive mechanism is disposed on the inner wall of the frame and is used to drive the transmission mechanism.

[0011] As a further embodiment of this utility model: the limiting mechanism includes a mounting bracket installed on one side of the upper test tube rack, a movable shaft rotatably mounted on the mounting bracket, a pressure plate mounted on the movable shaft, and a groove provided in the mounting bracket, with a torsion spring connected to the movable shaft disposed in the groove.

[0012] As a further embodiment of this utility model: the transmission mechanism includes fixed plates installed on both sides of the inner wall of the frame, guide rods are installed on the fixed plates, racks are slidably arranged on the guide rods, and gears that mesh with the racks are installed on the rotating shaft.

[0013] As a further embodiment of this utility model: the driving mechanism includes hydraulic rods installed on both sides of the inner wall of the frame, the hydraulic rods are fixedly connected to a driving plate, and the driving plate is fixedly connected to a rack.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model places several test tubes containing a mixture in an upper test tube rack and a lower test tube rack, and then uses a limiting mechanism to limit the top of the test tubes, preventing the test tube rack from moving within the upper and lower test tube racks during the mixing process, thus improving the stability of the test tube mixing process. The drive mechanism drives the transmission mechanism, which in turn drives the rotating shaft to rotate back and forth, causing the rotating frame to drive the placement rack to swing left and right, thereby ensuring that the mixture in the test tubes is fully mixed, avoiding the problems of time-consuming and laborious manual mixing and low shaking efficiency.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Please see Figures 1-2 A cell sorting device includes a frame 1, a rotating shaft 2 rotatably mounted inside the frame 1, two symmetrically distributed rotating frames 3 mounted on the rotating shaft 2, and a placement frame 4 mounted at the end of the rotating frame 3 away from the rotating shaft 2. The placement frame 4 is U-shaped, and the inner wall of the placement frame 4 is provided with a plurality of spaced upper test tube racks 5 and lower test tube racks 6, which are aligned. Test tube holes 7 are provided at corresponding positions on the upper test tube racks 5 and lower test tube racks 6 for placing test tubes. The device also includes:

[0020] A limiting mechanism is provided on the upper test tube rack 5 to limit the placement of the test tubes;

[0021] A transmission mechanism is provided between the frame 1 and the rotating shaft 2 to realize the rotation of the rotating shaft 2;

[0022] A drive mechanism is installed on the inner wall of the frame 1 and is used to drive the transmission mechanism.

[0023] By placing several test tubes containing the mixture into the upper test tube rack 5 and the lower test tube rack 6, and then limiting the top of the test tubes through the limiting mechanism, the test tube rack is prevented from moving within the upper test tube rack 5 and the lower test tube rack 6 during the mixing process, thus improving the stability of the test tube mixing process. The drive mechanism drives the transmission mechanism, which in turn drives the rotating shaft 2 to rotate back and forth, causing the rotating frame 3 to drive the placement frame 4 to swing back and forth left and right. This allows the mixture in the test tubes to be fully mixed, avoiding the time-consuming and laborious process and low shaking efficiency caused by manual mixing.

[0024] In one embodiment, the upper test tube rack 5 and the lower test tube rack 6 are each provided with a test tube hole 7 at corresponding positions for placing test tubes.

[0025] When placing the test tubes, first activate the limiting mechanism to open it, making it easier to place the test tubes into the test tube holes 7 of the upper test tube rack 5 and the lower test tube rack 6. Then release the limiting mechanism so that it automatically limits the test tubes, thus completing the test tube placement.

[0026] In one embodiment, the limiting mechanism includes a mounting frame 8 installed on one side of the upper test tube rack 5. A movable shaft 9 is rotatably mounted on the mounting frame 8, and a pressure plate 10 is mounted on the movable shaft 9. A groove 11 is provided in the mounting frame 8, and a torsion spring 12 connected to the movable shaft 9 is provided in the groove 11.

[0027] When placing the test tubes, first move the pressure plate 10 of the limiting mechanism to rotate it to a vertical position, so that the test tubes can be placed in the test tube holes 7 of the upper test tube rack 5 and the lower test tube rack 6. Then release the pressure plate 10. Under the elastic torque of the torsion spring 12, the movable shaft 9 will drive the pressure plate 10 to reset and press the top of the placed test tubes, thereby limiting the test tubes and preventing the test tube racks from moving within the upper test tube rack 5 and the lower test tube rack 6 during the mixing process, thus improving the stability of the test tube mixing process.

[0028] In one embodiment, the transmission mechanism includes fixed plates 16 installed on both sides of the inner wall of the frame 1, guide rods 15 are installed on the fixed plates 16, racks 14 are slidably arranged on the guide rods 15, and gears 13 that mesh with racks 14 are installed on the rotating shaft 2.

[0029] Driven by the drive mechanism, the rack 14 moves back and forth along the guide rod 15. During the movement of the rack 14, it drives the gear 13 to rotate back and forth, so that the rotating shaft 2 can drive the rotating frame 3 to swing back and forth, thereby driving the placement frame 4 to swing back and forth. This allows the mixture in the test tube to be fully mixed, avoiding the problems of laborious and inefficient shaking caused by manual mixing.

[0030] In one embodiment, the drive mechanism includes hydraulic rods 17 installed on both sides of the inner wall of the frame 1. Multiple hydraulic rods 17 are synchronized by a synchronizer. The hydraulic rods 17 are fixedly connected to a drive plate 18, and the drive plate 18 is fixedly connected to a rack 14.

[0031] When driving the transmission mechanism, the reciprocating extension and retraction of the hydraulic rod 17 can drive the drive plate 18 to move back and forth, thereby driving the transmission mechanism.

[0032] The working principle of this utility model is as follows: When placing test tubes, first move the pressure plate 10 of the limiting mechanism to rotate it to a vertical position, thus facilitating the placement of test tubes into the test tube holes 7 of the upper test tube rack 5 and the lower test tube rack 6. Then, release the pressure plate 10. Under the elastic torque of the torsion spring 12, the movable shaft 9 will drive the pressure plate 10 to reset, and the pressure plate 10 will press down on the top of the placed test tubes, thereby limiting the position of the test tubes and preventing the test tube racks from moving within the upper test tube rack 5 and the lower test tube rack 6 during the mixing process, thus improving the stability of the test tubes. Stability during the mixing process; When driving the transmission mechanism, the reciprocating extension and retraction of the hydraulic rod 17 can drive the drive plate 18 to move back and forth, which in turn can drive the rack 14 to move back and forth along the guide rod 15. During the movement of the rack 14, the gear 13 will be driven to rotate back and forth, so that the rotating shaft 2 can drive the rotating frame 3 to swing back and forth, which in turn drives the placement frame 4 to swing back and forth, thereby fully mixing the mixture in the test tube, avoiding the problems of laborious and low shaking efficiency caused by manual mixing.

[0033] This invention places several test tubes containing a mixture into an upper test tube rack 5 and a lower test tube rack 6. A limiting mechanism then limits the top of the test tubes to prevent the test tube rack from moving within the upper and lower test tube racks 5 and 6 during the mixing process, thus improving the stability of the test tube mixing process. A drive mechanism drives a transmission mechanism, which in turn drives a rotating shaft 2 to rotate back and forth, causing the rotating frame 3 to drive the placement frame 4 to swing left and right. This allows for thorough mixing of the mixture in the test tubes, avoiding the time-consuming, laborious, and inefficient shaking problems caused by manual mixing.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
