[0039] Such as Figures 1-7As shown in the figure, in a first aspect, an embodiment of the present application provides a bracket for a pipeline of a closed transfer system, which is used to fix the pipeline connected to the upper end of the cell factory 4. The pipeline has a connection end and a free end, and includes: a bracket body 1, which is used to place the pipeline of the closed transfer system and is transported synchronously with the pipeline of the closed transfer system and the cell factory 4. The upper end surface of the bracket body 1 bulges upward along the outer periphery of the bracket body 1 to form a clamping portion 11; a first clamping groove 12, which is arranged in a coiled shape on the upper end surface of the clamping portion 11 and is used to clamp the first pipeline, and makes the first pipeline be clamped in the first clamping groove 12 in a coiled shape; a first notch 19, which is arranged on the upper end surface of the clamping portion 11 and penetrates the inner and outer side walls of the clamping portion 11; a second clamping groove 17 is arranged at the bottom of the first notch 19, and the second clamping groove 17 is used to clamp the second pipeline 42, and makes the free end of the second pipeline 42 be placed inside the clamping portion 11, and the connection end be placed outside the clamping portion 11 for connection with the cell factory 4; the second clamping groove 17 is located below the first clamping groove 12, so that when the first pipeline 41 is clamped in the first clamping groove 12, the lower end of the first pipeline 41 presses against the upper end of the second pipeline 42; and a second notch 16, which is arranged on the upper end surface of the clamping portion 11 and communicates with the first clamping groove 12, so that the connection end of the first pipeline 41 extends outwards through the second notch 16 for connection with the cell factory 4. Wherein the first pipeline 41 is a liquid guide pipe and the second pipeline 42 is a breathable pipe.

[0040] In the specific use of this embodiment, the staff first places the bracket body 1 on the upper end surface of the cell factory 4 to be transported, then holds the free end of the second pipeline and enters the second pipeline from top to bottom at the first notch 19 into the second clamping groove 17, and is positioned by the second clamping groove 17; then holds the free end of the first pipeline and makes the first pipeline enter the first clamping groove 12 through the second notch 16, and presses the second pipeline downward along the extending direction of the first clamping groove 12 and snaps it into the first clamping groove 12, and is positioned by the first clamping groove 12; when the clamping and positioning of the first pipeline are completed, the lower end of the first pipeline at the position of the second notch 16 presses against the upper end of the second pipeline, which can also achieve the effect of assisting in positioning the second pipeline that has been snapped into the second clamping groove 17; after the positioning of the pipeline is completed, the bracket body 1 can be transported together with the cell factory 4 (the bracket body 1 and the cell factory 4 are packaged and fixed as a whole). Since the connection end of the pipeline is fixedly connected to the cell factory 4, and the free end of the pipeline is reliably positioned in the first clamping groove 12 and the second clamping groove 17, it effectively avoids the situation that the connection between the pipeline and the closed transfer system is prone to looseness due to vibration during the transfer of the closed transfer system, and effectively avoids the occurrence of liquid leakage; during the entire transportation process, the connection between the pipeline and the cell factory 4 remains reliable and stable, and it also avoids the occurrence of the situation that the inside of the cell factory 4 is polluted by the outside.

[0041] In some embodiments of the present application, the first clamping groove 12 includes a head section 121 with open ends, a tail section 122 provided outside the head section 121, and a connecting section 123 provided between the head section 121 and the tail section 122. The connecting section 123 has an entry end 1231 that cooperates with the tail section 122 and a delivery end 1232 that cooperates with the head section 121. The first pipeline enters the tail section 122 through the second notch 16, enters the connecting section 123 from the tail section 122 through the delivery end 1232, then extends out from the entry end 1231 of the connecting section 123 and enters the head section 121. Eventually, the first pipeline is spirally clamped and positioned within the first clamping groove 12. In this solution, there is no connection between the delivery end 1232 and the head section 121, so that the outer wall of the part of the first pipeline that enters the head section 121 through the delivery end 1232 (the first pipeline between the delivery end 1232 and the head section 121) abuts against the inner wall of the clamping portion 11, and a certain degree of limiting effect on the part of the second pipeline between the head section 121 and the connecting section 123 is achieved through the inner wall of the clamping portion 11.

[0042] In some embodiments of the present application, a third notch 13 is further provided between the entry end 1231 and the tail section 122 and penetrates the inner and outer side walls of the clamping portion 11, and at least a part of the free end of the first pipeline extends into the third notch 13. A fourth notch 14 is also provided in the connecting section 123 and penetrates the inner and outer side walls of the clamping portion 11, and the fourth notch 14 divides the connecting section 123 into two parts. The settings of the third notch 13 and the fourth notch 14, on the one hand, make the first pipeline clamped in the first clamping groove 12 in a suspended state at the positions of the third notch 13 and the fourth notch 14. When the pipeline needs to be removed from the bracket body 1, the first pipeline needs to be taken out of the first clamping groove 12 first. The staff only needs to pull the first pipeline body on the side of the third notch 13 and the fourth notch 14 upward by hand respectively, and the first pipeline can be easily taken out of the connecting section 123 and the tail section 122. At least a part of the free end of the first pipeline extends into the third notch 13, and the staff can easily take the first pipeline out of the head section 121 by pulling upward the free end of the first pipeline extending into the third notch 13. On the other hand, due to the settings of the third notch 13 and the fourth notch 14, the self-weight of the bracket body 1 is also reduced to a certain extent, improving the portability during transportation.

[0043] After the first pipeline is taken out, at this time, the second pipeline clamped in the second clamping groove 17 is no longer pressed by the first pipeline, and then the second pipeline can be taken out of the second clamping groove 17, thereby completing the effect of removing the pipeline from the bracket body 1.

[0044] In some embodiments of the present application, at least one set of first clamping members is provided inside the head section 121, the connecting section 123, and the tail section 122. The first clamping member includes first clamping protrusions 2 provided on opposite inner side walls of the head section 121, the connecting section 123, and the tail section 122, and the first pipeline is clamped between the two first clamping protrusions 2; at least one set of second clamping members is provided in the second clamping groove 17. The second clamping member includes second clamping protrusions 3 provided on opposite inner side walls of the second clamping groove 17, and the second pipeline is clamped between the two second clamping protrusions 3; when the first pipeline is in a coiled shape and located in the first clamping groove 12, the first pipeline is clamped by a plurality of cooperating first clamping protrusions 2, thereby realizing positioning and clamping of the first pipeline in the first clamping groove 12; similarly, when the second pipeline is placed in the second clamping groove 17, it is clamped in the second clamping groove 17 by the cooperating second clamping protrusions 3, thereby realizing the effect of positioning and clamping the second pipeline in the second clamping groove 17.

[0045] In some embodiments of the present application, the bracket body 1 inside the clamping portion 11 is recessed downward to form a receiving cavity 15, which can be used to place some other spare parts used during transportation, providing a certain degree of convenience for the transportation process; making the side wall of the receiving cavity 15 flush with the inner side wall of the clamping portion 11 helps to conveniently take out or put spare parts into the receiving cavity 15.

[0046] In some embodiments of the present application, a cavity 7 is provided between the outer side wall of the receiving cavity 15 and the bracket body 1. The setting of the cavity 7 helps to further reduce the self-weight of the bracket body 1, making it easier to pick up; at the same time, a plurality of concave-convex grooves 8 are provided on opposite side walls of the cavity 7, the outer wall of the bracket body 1, the inner side wall of the clamping portion 11, and the bottom of the receiving cavity 15; this can well increase the structural strength of the bracket body 1 and also make the appearance of the bracket body 1 more beautiful.

[0047] In some embodiments of the present application, a part of the bottom wall of the receiving cavity 15 protrudes upward to form a convex platform 18. The convex platform 18 divides the receiving cavity 15 into two parts. The setting of the convex platform 18 divides the receiving cavity 15 into two parts, which can be used for storing different spare parts in different regions according to transportation requirements, improving the flexibility of the bracket body 1. At the same time, the protruding setting further improves the structural strength of the bracket body 1. The preferred material of the bracket body 1 in this solution is PET, which is obtained by thermoforming the raw material. Specifically, the thickness of the PET raw material sheet is 1.5 mm, and the thickness of each position of the bracket body 1 obtained by thermoforming is different, ranging from 0.8 to 1.3 mm, and the protruding setting is more conducive to thermoforming.

[0048] In some embodiments of the present application, the depth of the first clamping groove 12 is greater than or equal to the outer diameter of the first pipeline. When the first pipeline is clamped in the first clamping groove 12, the upper end of the first pipeline does not protrude from the upper end surface of the clamping portion 11, ensuring the flatness of the upper surface of the bracket body 1 and not affecting its packaging and transportation.

[0049] As Figure 8 shown, in a second aspect, an embodiment of the present application provides a closed transfer system, including: a cell factory 4 for culturing cells, such as liquid transfer and culture during large-scale amplification of suspension cells, bacteria, etc.; the bracket for the pipeline of the closed transfer system in the above embodiment (fixing the pipeline of the closed transfer system); the bracket is placed on the upper end surface of the cell factory 4. The upper end of the cell factory 4 is respectively connected with a first pipeline 41 (for the inlet and outlet of liquid) and a second pipeline 42 (for ventilating the inside of the cell factory 4). The first pipeline 41 enters the first clamping groove 12 from the second notch 16 and is clamped in the first clamping groove 12 by the first clamping member. The second pipeline 42 passes through the second clamping groove 17 from outside to inside and is clamped in the second clamping groove 17 by the second clamping member; a liquid stop clamp 5 (a conventional clip structure) is provided at the position of the first pipeline 41 at the fourth notch 14, and the liquid stop clamp 5 is used to control the on-off of the first pipeline 41; a filter assembly 421 is provided at the inner end of the second pipeline 42 inside the clamping portion 11 for filtering air.

[0050] Figure 8 This is a schematic diagram of the cooperation relationship between the bracket body 1 and the cell factory 4 in the present solution during transportation. First, connect the pipelines of the closed transfer system (the first pipeline 41 and the second pipeline 42) to the cell factory 4. Place the bracket body 1 on the upper end of the cell factory 4, and position the first pipeline 41 and the second pipeline 42 on the bracket body 1 respectively to position the pipelines of the closed transfer system during transportation. The cell factory 4, the pipelines of the closed transfer system, and the bracket body 1 are packaged as a whole. During transportation and handling, the generated vibration and impact will not cause the conversion cover 6 to loosen, and the filter assembly 421 will not be damaged either. After arriving at the destination, just open the package and it can be used directly, effectively controlling the risk of liquid leakage, and the user does not need to perform a tightening action anymore.

[0051] When the closed transfer system in the present solution leaves the factory, the cell factory 4 and the pipelines are all sterilized. There is no liquid in the cell factory 4, and there is no requirement for whether the liquid stop clamp 5 provided on the first pipeline 41 is in a clamped state (only when the cell factory 4 is in use, that is, when there is liquid stored inside it, the first pipeline 41 is clamped by the liquid stop clamp 5 to achieve the effect of blocking the first pipeline 41 during the culture process). The free end of the first pipeline 41 can be hot-pressed by equipment to block and seal the first pipeline 41, or install corresponding joints according to customer requirements.

[0052] In some embodiments of the present application, conversion caps 6 are provided at one end of the first pipeline 41 and the second pipeline 42 connected to the cell factory 4 (a connection port matching the conversion cap 6 is provided at the upper end of the cell factory 4), so that the first pipeline 41 and the second pipeline 42 are connected to the connection port on the cell factory 4 through the conversion cap 6. A sealing silica gel ring 61 is provided inside the conversion cap 6, which can preferably prevent liquid leakage.

[0053] The working process of the present utility model is as follows: The staff first places the bracket body 1 on the upper end of the cell factory 4, and then inserts the second pipeline 42 from outside to inside into the second clamping groove 17 and is positioned by the second clamping groove 17; then presses the first pipeline 41 downward along the direction of the first clamping groove 12 in sequence and snaps it into the first clamping groove 12 to achieve the clamping and positioning of the first pipeline, and makes the lower end of the first pipeline press against the upper end of the second pipeline, thereby further assisting in positioning the second pipeline and improving the positioning effect; when it is necessary to remove the pipeline from the bracket body 1, first, the first pipeline needs to be removed from the bracket body 1, that is, just pull the first pipeline upward by hand at several notches, and the first pipeline clamped in the first clamping groove 12 can be easily removed from the bracket body 1. Since the first pipeline no longer presses against the upper end of the second pipeline, then the second pipeline can be taken out from the second clamping groove 17.

[0054] In summary, the embodiment of the present utility model provides a bracket for a pipeline of a closed transfer system and a closed transfer system. By setting the bracket body 1 and placing it on the cell factory 4, the free ends of the first pipeline 41 and the second pipeline 42 connected to the cell factory 4 are respectively positioned in the first clamping groove 12 and the second clamping groove 17, and the connection ends of the first pipeline 41 and the second pipeline 42 are respectively connected and fixed to the cell factory 4, so that during the transportation process of the cell factory 4, the pipelines can be reliably positioned on the bracket body 1, avoiding loosening at the connection between the pipelines and the cell factory 4 due to vibration during transportation, and further avoiding liquid leakage during the transfer of the cell factory 4; moreover, after the transportation process is over, there is no need to re-tighten the conversion cap 6, which more meets the requirements of reducing the potential pollution risks in the processes of liquid transfer, sampling, etc. in the industrial production of biological products; at the same time, other accessories of the cell factory 4 can also be placed in the accommodation cavity 15 in the bracket body 1, providing convenience for the transportation work of the cell factory 4.

[0055] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
