[0021] The utility model Figures 1 to 4 As shown, a multifunctional liquid guiding device includes a base 10, a load-bearing bracket 20, a placement platform 30 for placing a cell culture bag, a liquid guiding tube 40 for transferring liquid to the cell culture bag, and a control source 50 for controlling the flow rate of the liquid in the liquid guiding tube 40, wherein:

[0022] The load-bearing bracket 20 is vertically arranged on the base 10; the storage platform 30 can be raised and lowered on the load-bearing bracket 20; the storage platform 30 can be lowered to fit the upper surface of the base 10; the catheter 40 is connected between the control source 50 and the cell culture bag; and an anti-slip member 60 is provided at the connection position between the storage platform 30 and the load-bearing bracket 20.

[0023] The placement of the cell culture bag is facilitated by the use of the storage platform 30; the precise introduction of liquid into the cell culture bag is facilitated by the use of the control source 50 and the liquid guide tube 40, thereby improving the liquid guide accuracy and facilitating operation; the height of the storage platform 30 can be adjusted according to the requirements of use by arranging the storage platform 30 on the load-bearing bracket 20 in a liftable manner; and the stability of the storage platform 30 is ensured by the use of the anti-slip member 60 to prevent positional dislocation.

[0024] A multifunctional liquid-guiding device with a simple structure, high precision, and easy operation is provided. The device is placed in a biological safety cabinet and uses the gravity generated by the height and the extrusion potential energy provided by the peristaltic pump to quickly and accurately introduce the liquid into the container. The placement platform 30 and the load-bearing bracket 20 are fixed by mechanical extrusion force, and anti-slip parts 60 are used to prevent sliding and dislocation.

[0025] The storage platform 30 is liftably mounted on the support 20. When adding liquid, the storage platform 30 is lowered to the bottom of the support 20, allowing the liquid to flow into the cell culture bag faster due to the gravity potential energy. When collecting liquid from the cell culture bag, the storage platform 30 can be raised to the top of the support 20, where the liquid is affected by the gravity potential energy, accelerating the collection process and minimizing contact with the cell culture bag, thereby reducing the risk of contamination.

[0026] The control source 50 is a peristaltic pump, and there are two of them. The liquid guide tube 40 is a three-way hose, which includes an integrally connected manifold 41, a first branch pipe 42 and a second branch pipe 43. The two peristaltic pumps are distributed one-to-one with the first branch pipe 42 and the second branch pipe 43, and the two peristaltic pumps are symmetrically distributed.

[0027] The three-way hose adopts a Luer connector three-way liquid conduction hose; the Luer connector three-way liquid conduction hose can be used to connect two cell culture bags at the same time, thereby improving efficiency.

[0028] The anti-slip member 60 is anti-slip silica gel; there are two load-bearing brackets 20 and two anti-slip members 60, and the two load-bearing brackets 20 are respectively arranged on both sides of the storage platform 30, and the two anti-slip members 60 correspond one-to-one to the two load-bearing brackets 20.

[0029] The placement platform 30 is provided with two pads 31 for placing the cell culture bag. The two pads 31 are symmetrically distributed on the upper surface of the placement platform 30 .

[0030] Up to two 1L cell culture bags can be placed on the storage platform 30, which are connected through a Luer connector three-way liquid guide hose and a peristaltic pump is installed on the side of the Luer connector three-way liquid guide hose connected to the cell culture bag. A syringe is used as a funnel. When adding culture medium, the flow rate can be controlled by the peristaltic pump and evenly distributed into the two cell culture bags.

[0031] The two load-bearing brackets 20 are symmetrically fastened to both sides of the base 10 by welding.

[0032] The bottom plate and the load-bearing bracket 20 are connected by welding, which can ensure the strength, reliability and practicality of the connection structure between the bottom plate and the load-bearing bracket 20.

[0033] The base 10 and the storage platform 30 are both in the shape of square plates. The storage platform 30 is movable and can be raised and lowered above the base 10 . The size of the storage platform 30 does not exceed that of the base 10 .

[0034] The two pads 31 correspond to the first branch pipe 42 and the second branch pipe 43 respectively. A fastening bolt 70 is detachably provided between the storage platform 30 and the load-bearing bracket 20 .

[0035] The base plate, storage platform 30 and load-bearing bracket 20 are all made of 304 stainless steel. The use of 304 stainless steel can effectively reduce the damage to the material caused by long-term ultraviolet radiation while ensuring structural strength, and will not produce chemical reactions to disinfectants such as alcohol.

[0036] The method and principle of using the multifunctional liquid guiding device are as follows:

[0037] The peristaltic pump controls the rapid and precise introduction of liquid into the cell culture bag; the storage platform is fixed to the load-bearing bracket by mechanical extrusion force and prevented from sliding and dislocation by anti-slip parts; the storage platform is liftable on the load-bearing bracket. When adding liquid, the storage platform is lowered to the lower end of the load-bearing bracket, which allows the liquid to be affected by gravity potential energy and accelerate its flow into the cell culture bag; when collecting liquid in the cell culture bag, the storage platform can be raised to the upper end of the load-bearing bracket, so that the liquid is affected by gravity potential energy, accelerating the collection speed, reducing contact with the cell culture bag, and reducing the risk of contamination.

[0038] The design focus of the utility model is that the placement of the cell culture bag is facilitated by the use of a storage platform; the liquid is accurately introduced into the cell culture bag by the use of a control source and a liquid guide tube, thereby improving the liquid guide accuracy and facilitating operation; the height of the storage platform is adjusted according to the use requirements by arranging the storage platform in a liftable manner on a load-bearing bracket; and the stability of the storage platform is ensured by the use of anti-slip parts to prevent position dislocation.
