Cell culture bag for constant-current fluid infusion

Abstract

The cell culture bag comprises a supporting plate, a suction cup is connected to one side of the supporting plate, a first through hole is formed in the upper portion of the supporting plate, a supporting rod is connected to one side of the supporting plate, an injection body is connected to one end of the supporting rod, a clamping mechanism is connected to the upper end of the injection body, and a rotating mechanism is fixedly connected to the interior of the injection body. The lower end face of the rotating mechanism is connected with a pushing mechanism. The lower end face of the injection body is connected with a cell culture bag, the suction cup on the supporting plate is firstly selected to be adsorbed on a wall body or hung on a hook through the first through hole, the two fixing modes can also be used at the same time, and after the suction cup and the first through hole are fixed, the cell culture bag needs to be placed in the supporting groove in advance, and the cell culture bag is prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of biological cell culture, in particular to a cell culture bag used for constant flow infusion. Background technique [0002] In the field of immune cell therapy of tumors and scientific research fields such as biology, immunity, and medicine, cell culture technology is often used, and it is also the basis of almost all cell biology experiments. During cell culture, cells can continue to grow and reach a certain number by passage and rehydration. To achieve higher numbers of cells, larger cell culture bags are usually used. When using a cell culture bag to culture cells for passage or rehydration, a 50ml syringe is generally used as a funnel to connect the cell culture bag, and then the culture solution is poured into the syringe, and the culture solution flows into the cell culture bag through the syringe. Complete the passaging or rehydration process. [0003] Because the existing injection body is onl...

Problems solved by technology

[0003]Because the existing injection body is only suitable for the installation of culture fluid bottles, but the installed culture fluid bottles can only use suitable models, which are too single and cannot be multiple different The model can be installed with rehydration, and the bagged culture solution cannot be installed, which will reduce the applicability of the injection body and reduce work efficiency. The culture solution in the injection body will solidify with time, resulting in the flow channel of the culture solution being blocked or flowing. Slow, and when the culture medium is flowing in the guide tube, the guide tube sometimes bends greatly, resulting in slow flow or blockage of the culture medium
