[0002] Cell culture is a technique for culturing cells in vitro for experimental research, drug production, etc. Cell culture bags are tools used to culture cells in vitro, and are widely used in fields such as cell therapy and vaccine production. Cell culture bags are usually made of plastic materials, including polyester, polypropylene, etc., and are often used in the production of vaccines, cell therapy, gene therapy, immunotherapy, and tissue engineering. The cell culture bag clamp is a device used to adjust the volume of the cell culture bag. When the cells in the culture bag proliferate to a certain number and exceed a certain density, the volume of the culture bag is adjusted by the clamp, so that the cells have enough space to continue to reproduce and divide without being contaminated by the outside world.

[0029] Example 1

[0030] like Figure 1-3 As shown, the utility model proposes a special clamp for cell culture bags, including a base 1, on which a culture bag 4 is placed, and also includes a back plate 2 fixedly installed on the base 1, on which a frame 3 is provided, and the frame 3 includes a fixed frame 31 and a movable frame 32. A placement groove 101 for placing the culture bag 4 is opened on the top of the base 1, the fixed frame 31 is fixedly installed on one side of the base 1, and the movable frame 32 is slidably installed on one side of the fixed frame 31.

[0031] Among them, a clamp seat 6 is movably installed between the fixed frame 31 and the movable frame 32. There are multiple clamp seats 6, and their lengths are different. The specific length is determined according to the different common sizes of the culture bag 4. The clamp seat 6 is movably connected between the mounting block 8 and the buckle seat 7 by bolts. A clamp plate 5 is hinged on the fixed frame 31. A slide bar 10 is fixedly installed on the fixed frame 31. The movable frame 32 is slidably sleeved on the slide bar 10. Guide rods 301 are fixedly installed in both the fixed frame 31 and the movable frame 32. The guide rods 301 are respectively slidably sleeved with the mounting block 8 and the buckle seat 7. The mounting block 8 is slidably installed in the fixed frame 31, and the buckle seat 7 is slidably installed in the movable frame 32. According to the size of the culture bag 4, the position of the movable frame 32 is adjusted, and then the clamp seat 6 of suitable length is fixedly connected between the mounting block 8 and the buckle seat 7 to complete the assembly of the device.

[0032] In addition, the clamp seat 6 is fixedly installed between the mounting block 8 and the snap seat 7. A rectangular groove 302 for sliding the clamp seat 6 is provided on one side of the fixed frame 31 and the movable frame 32 close to the clamp seat 6. A plurality of groups of grooves 601 are provided on the clamp seat 6. A plurality of groups of convex strips 501 matching the shape of the grooves 601 are fixedly installed on one side of the clamp plate 5 close to the clamp seat 6. The convex strips 501 on the clamp plate 5 enter into the grooves 601 on the clamp seat 6, so that the clamp plate 5 and the clamp seat 6 are relatively fixed, thereby realizing the transverse separation and sealing of the culture bag 4.

[0033] In this embodiment, a buckle assembly is provided on the clamping plate 5 and the clamping seat 6. The buckle assembly includes a rectangular plate 16 slidably mounted on the clamping plate 5, and the insert 9 is fixedly mounted on both sides of the rectangular plate 16. The buckle assembly also includes a mounting groove 701 opened in the clamping seat 7, and a movable plate 12 is slidably mounted in the mounting groove 701. A round rod is fixedly mounted in the mounting groove 701, and the movable plate 12 is slidably sleeved on the round rod. A control rod 14 is fixedly mounted on the side of the movable plate 12 away from the insert 9, and a handle is fixedly connected to one end of the control rod 14 located outside the clamping seat 7. Pulling the handle causes the control rod 14 and the movable plate 12 to move in a direction away from the insert 9, so that the block 15 fixedly connected to the movable plate 12 is separated from the slot on the insert 9, thereby releasing the relative fixation between the clamping plate 5 and the clamping seat 6, which is convenient for next use.

[0034] Among them, the buckle assembly also includes a block 15 fixedly installed on the side of the moving plate 12 close to the insert 9, and a slot that matches the shape of the block 15 is opened on one side of the insert 9. A spring 13 is fixedly connected between the side of the moving plate 12 away from the control rod 14 and the installation slot 701. When the insert 9 is inserted into the buckle seat 7, the block 15 fixedly installed on one side of the moving plate 12 is inserted into the slot on the insert 9 under the action of the spring 13, thereby fixing the insert 9 and realizing the transverse separation and sealing of the culture bag 4.

[0035] Example 2

[0036] like Figure 4 As shown, based on Example 1, when adjusting according to the size of the culture bag 4, slide grooves 502 are opened on both sides of the splint 5, and sliders adapted to the slide grooves 502 are fixedly installed on the inner side of the insert 9. The sliders on both sides of the insert 9 slide in the slide grooves 502. A limit plate 11 is fixedly installed on the top of the splint 5. The limit plate 11 is used to prevent the insert 9 from separating from the splint 5, so that it can be used on culture bags 4 of different sizes, further improving the practicability of the device and facilitating its popularization and use.
