[0021] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0022] Referring to Figures 1-5 As shown in the figure, a kind of cell culture bag is hung in the rack, including support body 1, receiving piece 2 is equipped on support body 1, and the middle part of support body 1 and receiving piece 2 is rotatably connected, rotating rod 51 is rotatably connected in one end of support body 1, and is used to hang culture bag, and rotating rod 52 is rotatably connected in the other end of support body 1, and is used to place injection container and liquid receiving container, for example, when supplementing liquid to the inside of cell culture bag, syringe barrel and the like injection container can be placed in the inside of placing ring 4, then culture bag is hung in the culture bag hanging piece 5, and culture bag is communicated with injection container, according to the need of experiment, receiving piece 2 is rotated, and injection container is rotated to appropriate height, and corresponding culture bag is rotated to lower position, and because placing ring 4 and culture bag hanging piece 5 are rotatably connected on receiving piece 2, when receiving piece 2 is rotated, placing ring 4 and culture bag hanging piece 5 can be self-adaptively adjusted, so as to present vertical state, and the one end of first locking screw 3 rotatably connected on receiving piece 2 is tightly contacted with support body 1, so as to realize the fixation of receiving piece 2, at this time, solution in the inside of injection container flows to the inside of culture bag under the action of gravity, and realizes the supplement of liquid in culture bag, when liquid in the inside of culture bag is poured out, cell tube and the like liquid receiving container can be placed in the inside of placing ring 4, and receiving piece 2 is rotated, and culture bag is rotated to appropriate height, and corresponding liquid receiving container is located in lower position, and receiving piece 2 is fixed by first locking screw 3, at this time, liquid in the inside of culture bag flows into liquid receiving container under the action of gravity, in the process of operation, culture bag and injection container or liquid receiving container reach the best operating position, improve the versatility and adaptability of the whole device when using, and in some experimental needs, in the continuous operation of supplementing liquid in culture bag or pouring out liquid in culture bag, operation can be quickly carried out, and the overall efficiency of experiment is improved.

[0023] Referring to Figure 3 , Figure 4As shown, further, in order to flexibly adjust the use state of the cell culture bag, the culture bag hanging piece 5 comprises a rotating rod 51 rotatably connected with the receiving piece 2 and a support plate 52 hinged with the rotating rod 51, and a hook 7 is arranged on the support plate 52. In use, the cell culture bag is hung on the hook 7 to support the cell culture bag. When the liquid is supplemented into the cell culture bag, the cell culture bag is at a lower position. When the liquid flows into the cell culture bag, the problems such as liquid splashing and bubble generation caused by height difference and liquid impact may cause mechanical damage to the cells. At this time, the support plate 52 can be rotated to the upper side of the rotating rod 51, so that the cell culture bag is placed on the support plate 52, and the second locking screw 6 threaded on the receiving piece 2 is rotated to tightly abut one end of the rotating rod 51, so as to limit the rotation of the rotating rod 51 and prevent the cell culture bag from separating from the support plate 52. When the cell culture bag is placed horizontally, the relative position of the cell culture bag inlet and the liquid in the cell culture bag is relatively stable. Under the action of gravity and liquid supplement pressure, the liquid can flow more smoothly into the cell culture bag, reducing the problems such as liquid splashing and bubble generation caused by height difference and liquid impact, which helps to maintain the stability of the cell culture environment and avoid physical damage to the cells. However, when the liquid in the cell culture bag is poured out, the support plate 52 can be rotated to make the cell culture bag present a vertical state. At this time, the gravity makes the liquid flow more fully into the liquid receiving container, reducing the residual liquid in the cell culture bag, which is conducive to discharging the liquid in the cell culture bag as much as possible and improving the integrity of the liquid collection. Moreover, the stability of liquid outflow is higher in the vertical state, and the flow rate is not easy to change due to uneven liquid distribution or flow resistance change.

[0024] In order to keep the stability of the support plate 52, a third locking screw 8 for fixing the position of the support plate 52 is threaded on the support plate 52. When the support plate 52 presents a vertical state or a horizontal state, the third locking screw 8 can be screwed to tightly abut the hinged shaft between the support plate 52 and the rotating rod 51, so as to limit the hinged shaft and fix the use state of the support plate 52, thereby enhancing the stability of the cell culture bag.

[0025] Referring to Figures 1-4 As shown, further, in order to adapt to different experimental requirements, the receiving piece 2 is of a telescopic structure at both ends, which can be an electric telescopic rod or the like. According to different experimental requirements, the distance between the placing ring 4 and the culture bag hanging piece 5 can be adjusted. Some experiments may need to closely place the liquid injection container and the cell culture bag in order to quickly and accurately transfer the liquid, while some experiments need to maintain a certain distance to avoid cross contamination or meet specific operation procedures. The telescopic structure of the receiving piece 2 can flexibly adjust the distance according to specific experimental requirements, thereby enhancing the flexibility in use.

[0026] Referring toFigures 1-5 As shown, further, in order to facilitate the support fixed liquid container or liquid container, the inner wall of the placement ring 4 is provided with elastic ring 9 of rubber, silica gel and other materials, when the liquid container or liquid container is placed in the inside of the placement ring 4, the elastic ring 9 can provide uniform pressure around the container, ensure that the container can be stable support in all directions, adaptive adjustment of pressure, so that the container is more stable placed on the placement ring 4, and can adapt to different size of the liquid container or liquid container.

[0027] Referring to Figure 3 As shown, further, in order to maintain the stability of the whole device during the experiment, a plurality of suction cups 10 are arranged on the bottom of the support body 1, and the support body 1 is placed on the operating table surface during use and is pressed under the action of gravity. The suction cup 10 is in close contact with the operating table surface and squeezes the air in the suction cup 10, so that the suction cup 10 is tightly adsorbed on the operating table surface, and the stability of the whole device can be ensured during the experiment.

[0028] The above shows and describes the basic principle and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
