Description

Technical Field

[0001] This utility model relates to the field of stem cell culture technology, and in particular to a stem cell culture bag hanging rack. Background Technology

[0002] Stem cell culture, as a crucial component of modern biomedical research, is widely applied in tissue engineering, regenerative medicine, and disease treatment. During stem cell culture, the suspension and fixation of the culture bag is a critical operational step, directly affecting the stable storage of the culture medium and the smooth progress of subsequent operations. To improve the safety and efficiency of experimental procedures, there is an urgent need for a suspension device with a reasonable structure, convenient operation, and good clamping stability to meet the high standards of stem cell culture bag management required in laboratory and clinical applications.

[0003] Currently, most commercially available stem cell culture bag suspension devices use a single hook or simple clamping structure, which can only achieve single-point suspension or partial fixation. This results in problems such as insecure clamping, easy shaking, and even detachment. Especially during liquid drainage or transportation, external forces or improper operation can easily cause the culture bag to shift or break, affecting experimental safety and the accuracy of results. Furthermore, some devices lack an effective pressure-applying structure when extruding the culture medium, leading to uneven pressure distribution and potential liquid splashing or residue, affecting operational convenience and experimental repeatability. Therefore, there is an urgent need to improve existing suspension structures to achieve multi-point stable clamping of the culture bag and provide a uniform and controllable extrusion method, thereby improving overall safety and operational efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stem cell culture bag suspension frame. By controlling the rotation of the rotating plate with a lever, the hooks and clamps can clamp the culture bag at multiple points. The ratchet spring mechanism prevents reverse rotation and improves clamping stability. The pressure plate, hanging plate and sliding silicone pressure strip are used to achieve uniform pressure, so that the culture medium can be discharged smoothly, improving extrusion efficiency and operational accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stem cell culture bag hanging rack, comprising an experimental table, a support fixedly connected to the upper end of the experimental table, a plurality of spherical hinge seats fixedly connected to the top of the inner wall of the support, a connecting rod fixedly connected to the lower end of the spherical hinge seats, a fixing plate fixedly connected to the lower end of the connecting rod, a fixing rod fixedly connected to the left side of the upper end of the fixing plate, a lever rotatably connected to the outer wall of the fixing rod, a first end face ratchet connected to the front end of the fixing rod via an elastic component, a rotating plate fixedly connected to the lower end of the lever, clamping plates fixedly connected to the lower right side of the rotating plate and the lower left side of the fixing plate, a hanging plate fixedly connected to the lower end of the fixing plate, a transparent pressure plate hinged to the lower end of the rotating plate, and a silicone pressure strip provided on the right side of the transparent pressure plate.

[0006] Furthermore, the elastic component includes a limiting block fixedly connected to the front end of the fixing rod, a spring is sleeved on the outer wall of the front end of the fixing rod, and a second end face ratchet is provided at the rear end of the spring, with the first end face ratchet engaged with the rear side of the second end face ratchet.

[0007] Furthermore, the front end of the spring is connected to the rear side of the limiting block, and the rear end of the spring is connected to the front side of the second end face ratchet.

[0008] Furthermore, both the second end face ratchet and the first end face ratchet are sleeved on the outer wall of the fixed rod, and a handle is fixedly connected to the outer wall of the second end face ratchet.

[0009] Furthermore, the rear end of the first end face ratchet is fixedly connected to the front side of the lever.

[0010] Furthermore, a hook is fixedly connected to the middle of the left side of the fixing plate, and the inner side of the clamping plate is provided with anti-slip texture.

[0011] Furthermore, a groove is provided on the inner wall of the right side of the transparent pressure plate, and a slider is slidably connected to the inner wall of the groove.

[0012] Furthermore, the silicone pressure strip is fixedly connected to the right end of the slider.

[0013] This utility model has the following beneficial effects: 1. In this invention, the rotation of the rotating plate is controlled by a lever, allowing the upper hook and lower clamping plate to work together to achieve multi-point stable clamping of the stem cell culture bag, avoiding the safety hazards such as swaying, displacement, or even detachment that are prone to occur with traditional single-point suspension. Simultaneously, during the clamping process, a spring reset mechanism automatically engages the end-face ratchet, preventing the lever from reversing, further enhancing the stability and safety of the clamping structure. This makes it suitable for various experimental operating environments, ensuring the safety of operators and experimental samples.

[0014] 2. In this invention, the stem cell culture bag is positioned and fixed by the cooperation of the pressure plate and the hanging plate, and uniform pressure is applied from top to bottom by the sliding silicone pressure strip, allowing the liquid inside the bag to be discharged smoothly and controllably, avoiding liquid splashing or residue problems caused by uneven pressure. This structural design not only improves extrusion efficiency but also enhances the convenience and precision of operation, making it particularly suitable for cell culture and biological experiment scenarios with high requirements for liquid control, thus improving the overall user experience and the reliability of experimental results.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a stem cell culture bag hanging rack, including an experimental table 1. A support 2 is fixedly connected to the upper end of the experimental table 1. Several spherical hinge seats 3 are fixedly connected to the top of the inner wall of the support 2. A connecting rod 4 is fixedly connected to the lower end of the spherical hinge seats 3. A fixing plate 5 is fixedly connected to the lower end of the connecting rod 4. A hook 6 is fixedly connected to the middle of the left side of the fixing plate 5. A fixing rod 14 is fixedly connected to the upper left side of the fixing plate 5. A lever 9 is rotatably connected to the outer wall of the fixing rod 14. A limiting block 15 is fixedly connected to the front end of the fixing rod 14. A spring 13 is sleeved on the outer wall of the front end of the fixing rod 14. A spring 13 is provided at the rear end of the spring 13. A second end face ratchet 11 is provided. The front end of the spring 13 is connected to the rear side of the limiting block 15, and the rear end of the spring 13 is connected to the front side of the second end face ratchet 11. The rear side of the second end face ratchet 11 is engaged with a first end face ratchet 10. The rear end of the first end face ratchet 10 is fixedly connected to the front side of the lever 9. Both the second end face ratchet 11 and the first end face ratchet 10 are sleeved on the outer wall of the fixed rod 14. A handle 12 is fixedly connected to the outer wall of the second end face ratchet 11. A rotating plate 8 is fixedly connected to the lower end of the lever 9. A clamping plate 7 is fixedly connected to the lower right side of the rotating plate 8 and the lower left side of the fixed plate 5. The inner side of the clamping plate 7 is provided with anti-slip texture.

[0019] Specifically, when using this device, first turn the lever 9 clockwise, causing the rotating plate 8 to rotate clockwise synchronously. At this time, the first end face ratchet 10 installed on the front side of the lever 9 will rotate accordingly, pushing the second end face ratchet 11 forward and compressing the internal spring 13. When the lever 9 stops rotating, the spring 13, under the action of the rebound force, pushes the second end face ratchet 11 to return to its original position, so that it re-engages with the first end face ratchet 10, thereby effectively preventing the first end face ratchet 10 from rotating in the opposite direction and ensuring the structural locking stability. After the rotating plate 8 completes the clockwise rotation, the stem cell culture bag can be smoothly hung on the hook 6. Then push the handle 12 forward, causing the second end face ratchet 11 to compress the spring 13 forward again, while the lever 9 rotates the rotating plate 8 counterclockwise, so that the clamping plate 7 on the lower right side of the rotating plate 8 and the clamping plate 7 on the lower left side of the fixed plate 5 cooperate with each other to firmly clamp the top of the stem cell culture bag. This surface clamping design effectively avoids the breakage risk that may be caused by single-point suspension and improves operational safety. After clamping is complete, release handle 12. Spring 13 pushes the second end face ratchet 11 to reset and re-engage with the first end face ratchet 10, preventing the lever 9 from rotating in the opposite direction and further ensuring the reliability of clamping. The ball joint 3 can reduce the impact of accidental collisions and reduce the shaking of the stem cell culture bag in the event of an accidental collision.

[0020] Reference Figure 1 and Figure 4 A hanging plate 16 is fixedly connected to the lower end of the fixed plate 5, and a transparent pressure plate 17 is hinged to the lower end of the rotating plate 8. A silicone pressure strip 20 is provided on the right side of the transparent pressure plate 17. A sliding groove 18 is opened on the inner wall of the right side of the transparent pressure plate 17. A slider 19 is slidably connected to the inner wall of the sliding groove 18. The silicone pressure strip 20 is fixedly connected to the right end of the slider 19.

[0021] Specifically, when liquid extrusion is required from the stem cell culture bag, the pressure plate and hanging plate 16 are first engaged to press down on the designated position of the culture bag. Then, the silicone pressure strip 20 is slid downwards to achieve uniform compression of the bag, allowing the culture medium to be discharged smoothly and steadily. This design not only improves the ease of operation but also ensures the uniformity and controllability of the extrusion process, thereby enhancing the overall safety and efficiency of use.

[0022] Working principle: When using this device, first turn the lever 9 clockwise to drive the rotating plate 8 to rotate clockwise. When the first end face ratchet 10 on the front side of the lever 9 rotates clockwise, it will push the second end face ratchet 11 to move forward, so that the second end face ratchet 11 compresses the spring 13. When the lever 9 stops rotating, the second end face ratchet 11 moves backward under the rebound force of the spring 13 and engages with the first end face ratchet 10, and restricts the first end face ratchet 10 from reversing. After the rotating plate 8 rotates clockwise with the lever 9, the stem cell culture bag is hung on the hook 6. Moving the handle 12 forward moves the second end-face ratchet 11 forward and compresses the spring 13. Then, rotating the rotating plate 8 counterclockwise with the lever 9 causes the clamping plate 7 on the lower right side of the rotating plate 8 and the clamping plate 7 on the lower left side of the fixing plate 5 to work together to clamp the top of the stem cell culture bag, preventing the risk of breakage due to single-point suspension. After stable clamping, the handle 12 is released. Under the rebound force of the spring 13, the second end-face ratchet 11 is pushed backward, re-engaging with the first end-face ratchet 10 and preventing the first end-face ratchet 10 from flipping, ensuring stable clamping. When it is necessary to extrude the stem cell culture bag, the pressure plate is rotated in conjunction with the hanging plate 16 to press the stem cell culture bag down. Then, the silicone pressure strip 20 is slid downward to evenly extrude the culture medium. This design makes the extrusion of the culture medium uniform and convenient.

[0023] It is worth noting that the spherical hinge, protective cover, and experimental platform involved in the above embodiments all adopt corresponding existing technologies according to the actual situation, so they will not be described in detail in the embodiments of this application.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
