Abstract
Description
Technical Field
[0001] This utility model relates to the field of stem cell separation technology, and more specifically, to a stem cell separation device. Background Technology
[0002] Stem cells are primitive cells with self-renewal and multi-directional differentiation potential. They are the origin cells of the body and can differentiate into one or more types of cells that constitute human tissues or organs under specific conditions. They can produce at least one type of highly differentiated daughter cells. Currently, most stem cell isolation methods use centrifugation. However, existing technologies have the following shortcomings:
[0003] Different types of stem cells require different angular velocities for centrifugation. Existing stem cell separation devices are often only capable of separating one type of single cell, resulting in low adaptability in practical applications.
[0004] Therefore, there is an urgent need for a stem cell separation device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the problem that existing stem cell separation devices often only allow for the separation of one type of single cell, which is insufficient for practical use because different types of stem cells require different angular velocities during centrifugation.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A stem cell separation device to improve the above-mentioned problems.
[0008] The application is as follows:
[0009] A stem cell separation device includes a worktable with a control switch on top. A drive motor is mounted on the lower surface of the worktable, and a drive shaft is fixedly connected to the output end of the drive motor. A drive gear is fixedly connected to the top of the drive shaft. A first connecting rod is rotatably connected to the top of the worktable via a first bearing. A first transmission gear meshing with the drive gear is fixedly connected to the top of the first connecting rod. A second connecting rod is rotatably connected to the top of the worktable via a second bearing. A second transmission gear meshing with the drive gear is fixedly connected to the top of the second connecting rod. A third connecting rod is rotatably connected to the top of the worktable via a third bearing. A third transmission gear meshing with the drive gear is fixedly connected to the top of the third connecting rod. A holder for placing test tubes is fixedly connected to the center of the top of each of the first, second, and third transmission gears.
[0010] As a preferred technical solution of this application, the top of the placement rack is provided with symmetrically distributed connecting blocks, and a threaded rod is provided through the connecting block with a transverse thread. One end of the threaded rod is fixedly connected to a circular block, and the other end of the threaded rod is rotatably connected to an arc-shaped block.
[0011] As a preferred technical solution of this application, symmetrically distributed guide blocks are fixedly connected to the arc-shaped block, and the guide blocks movably pass through the connecting block.
[0012] As a preferred technical solution of this application, the drive motor is electrically connected to the control switch.
[0013] As a preferred technical solution of this application, the first transmission gear and the drive gear have the same specifications, the diameter of the second transmission gear is larger than the diameter of the first transmission gear, and the diameter of the third transmission gear is smaller than the diameter of the first transmission gear.
[0014] As a preferred technical solution of this application, the connecting block is fixedly connected to the placement rack.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In the scheme of this application:
[0017] The staff placed three test tubes into three separate racks, then rotated multiple circular blocks. These blocks, in turn, rotated threaded rods, causing arc-shaped blocks to fit against the test tubes and secure them in place. A control switch then activated the drive motor, which in turn drove a drive gear via a drive shaft. This drive gear, in turn, rotated the first, second, and third transmission gears. Because these gears have different specifications, they generate different angular velocities. Since centrifugal force is proportional to angular velocity, the three test tubes experience different centrifugal forces. This allows for the simultaneous separation of multiple types of stem cells, making it more practical and applicable to a wider range of situations. It solves the problem that existing stem cell separation devices often only allow for the separation of one type of single cell, resulting in limited adaptability in practical use, as different types of stem cells require different angular velocities for centrifugation.

[0030] Example:
[0031] like Figure 1-5 As shown, this embodiment of a stem cell separation device includes a workbench 1. A control switch 2 is located on the top of the workbench 1. A drive motor 3 is mounted on the lower surface of the workbench 1. The drive motor 3 is activated by the control switch 2. A drive shaft 4 is fixedly connected to the output end of the drive motor 3. A drive gear 5 is fixedly connected to the top of the drive shaft 4. The drive motor 3 drives the drive gear 5 to rotate via the drive shaft 4. A first connecting rod 6 is rotatably connected to the top of the workbench 1 via a first bearing. A first transmission gear 7, meshing with the drive gear 5, is fixedly connected to the top of the first connecting rod 6. A second connecting rod 8 is rotatably connected to the top of the workbench 1 via a second bearing. A second transmission gear 9, meshing with the drive gear 5, is fixedly connected to the top of the second connecting rod 8. The top of the workbench 1... A third connecting rod 10 is rotatably connected via a third bearing. A third transmission gear 11, which meshes with the drive gear 5, is fixedly connected to the top of the third connecting rod 10. When the drive gear 5 rotates, it drives the first transmission gear 7, the second transmission gear 9, and the third transmission gear 11 to rotate. A placement rack 12 for placing test tubes is fixedly connected to the center of the top of each of the first transmission gear 7, the second transmission gear 9, and the third transmission gear 11. Since the diameters of the first transmission gear 7, the second transmission gear 9, and the third transmission gear 11 are different, the rotational speeds generated by the three gears are also different when the rotational speed of the drive gear 5 remains constant. The centrifugal force is proportional to the angular velocity, so the centrifugal force on the three test tubes is different, which facilitates the simultaneous separation and processing of multiple different types of stem cells.
[0032] like Figure 4 As shown, the top of the placement rack 12 is provided with symmetrically distributed connecting blocks 13. A threaded rod 14 is threaded through the connecting block 13 with a transverse thread. One end of the threaded rod 14 is fixedly connected to a circular block 15, and the other end of the threaded rod 14 is rotatably connected to an arc-shaped block 16. The staff places three test tubes into the three placement racks 12 respectively, and then rotates multiple circular blocks 15. The circular blocks 15 drive the threaded rod 14 to rotate, so that the arc-shaped block 16 fits against the test tube, and the test tube is fixed by the arc-shaped block 16.
[0033] like Figure 4 As shown, symmetrically distributed guide blocks 17 are fixedly connected to the arc-shaped block 16. The guide blocks 17 move through the connecting block 13. When the arc-shaped block 16 moves, it is guided by the guide rod 17 to prevent the arc-shaped block 16 from deviating.
[0034] like Figure 2 and Figure 3 As shown, the drive motor 3 is electrically connected to the control switch 2, and the drive motor 3 is started by controlling the control switch 2.
[0035] like Figure 2 As shown, the first transmission gear 7 has the same specifications as the drive gear 5. The diameter of the second transmission gear 9 is larger than that of the first transmission gear 7, and the diameter of the third transmission gear 11 is smaller than that of the first transmission gear 7. Since the diameters of the first transmission gear 7, the second transmission gear 9, and the third transmission gear 11 are different, the rotational speeds generated by the three gears are also different when the rotational speed of the drive gear 5 remains constant. The centrifugal force is proportional to the angular velocity, so the centrifugal force on the three test tubes is different, which makes it convenient to separate and process multiple different types of stem cells at the same time.
[0036] like Figure 4 As shown, the connecting block 13 is fixedly connected to the placement rack 12.
[0037] Specifically, when using this stem cell separation device: the operator places three test tubes into three separate racks 12, then rotates multiple circular blocks 15. These circular blocks 15 drive the threaded rod 14 to rotate, causing the arc-shaped block 16 to fit against the test tubes, thus fixing the test tubes in place. Then, the control switch 2 starts the drive motor 3, which drives the drive gear 5 via the drive shaft 4. When the drive gear 5 rotates, it drives the first transmission gear 7, the second transmission gear 9, and the third transmission gear 11 to rotate. Because the diameters of the first transmission gear 7, the second transmission gear 9, and the third transmission gear 11 are different, their rotational speeds differ even when the rotational speed of the drive gear 5 remains constant. Since centrifugal force is proportional to angular velocity, the three test tubes experience different centrifugal forces, facilitating the simultaneous separation of multiple different types of stem cells. This method is more practical and has a wider range of applications.
[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
