PROBLEM TO BE SOLVED: To eliminate the need for confirmation of the liquid level of a quantifying cylinder and set accurately the optional quantity of a drug solution by providing a graduated quantifying cylinder in which a sliding member having a vent and an inlet in the upper end and a hollow pusher in the inside is provided liquidtightly and a dripping cylinder connected to the lower end of the pusher. SOLUTION: When dripping with a transfusion set 1, first of all, a dosage is confirmed and set to a graduation 131, a sliding member 15 is moved by moving a pusher 16 up and down in accordance with the dosage. Subsequently, an introduction means 11 is penetrated into an output port, and a drug solution is introduced into a quantifying cylinder 13. At this time, when air in the inside is exhausted outwardly in accordance with the quantity of an infusion and the quantifying cylinder 13 is filled with a prescribed quantity of an infusion, the drug solution stops flowing in. After that, after the cylinder is filled half with the infusion by pumping operation by compressing a dripping cylinder 17, the lower portion of a transfusion line is deaerated, and lower and the upper clamps 181 and 121 are closed to close the upper transfusion line. Subsequently, the administration speed is adjusted by adjusting the lower clamp 181 while confirming the dripping speed. |
