した時点で液体の排出は終了する。 The float valve 4 quickly floats up and continues to rise until its upper surface collides with the lower surface of the valve stopper 5. After introducing a predetermined amount of liquid, when injecting the liquid into the patient, the clamp 16 is opened to drain the liquid in the chamber 1. The liquid is discharged through the drip tube 10, the liquid discharge tube 11, and the injection needle 12, and the discharge of the liquid ends when the lower surface of the float valve 4 comes into contact with the liquid outlet 3.
