Disposable biological process bag with stirring function

The utility model relates to a disposable biotechnological bag with a stirring function. The disposable biotechnological bag comprises a three-dimensional liquid storage bag, a round bag buckle connector, a first silicone tube, a second silicone tube, a third silicone tube, a first thermoplastic tube, a second thermoplastic tube, a third thermoplastic tube, a reducer union, a Luer taper, a needleless sampler, a male head, a female plug, a female seat, a male plug and a protective sleeve. A feeding valve is mounted on the three-dimensional liquid storage bag; a stirring device is mounted on the bottom surface in the three-dimensional liquid storage bag; the three-dimensional liquid storage bag has the advantages that the reaction efficiency in the reaction bag is improved, the reaction is sufficient, and due to the combined design of the Luer taper and the needleless sampler, when liquid in the three-dimensional liquid storage bag needs to be detected, a small amount of liquid can be directly taken out from th
