The utility model relates to a disposable transfusion flow regulator, which is composed of a casing, a damping sleeve which is arranged in the casing, a sealing ring, a rotating core, a turn knob which is connected with the rotating core into integration and connecting nozzles of an inlet and an outlet, wherein the connecting nozzles are respectively connected with a transfusion tube, and an outer circle of the turn knob is designed into a tooth-shaped structure; an arm-shaped collapse-resistant device and a balance block which is symmetrical with the collapse-resistant device are arranged on the casing; the collapse-resistant device is engaged with the turn knob. The utility model has the advantages that the utility model can be engaged with teeth on the periphery of the turn button to play the role of positioning by the arm-shaped collapse-resistant device and the balance block which is symmetrical with the collapse-resistant device; besides, the damping sleeve in the casing can be protected, therefore deformation can not be caused to affect the accuracy of the flow. Because the regulator does not need driving by energy sources, the utility model can be operated simply and used conveniently; therefore, the utility model can widely satisfy the operating requirements in any occasion.
