PURPOSE: To prevent a trouble for a long time, simultaneously, to reduce an error, and to facilitate the operations of the switching of a pump, a washing, etc., by mountable and removably linking the main moving shaft and driving shaft of the pump and using the pump in which a displacement is fixed.
CONSTITUTION: A transfused liquid from a liquid-transfusing bag 1 goes through an instillation cylinder 2 into the liquid suction port of a gear pump 4, exhausted from an exhaust port, and introduced through a filter 5 from a catheter 6 to the necessary part of a patient. In a driver 7, a power source battery, a small- sized motor, a drive control circuit, a conditions setting dial, etc., are incorporated, a driving shaft 8 of the driver is made into a hexagonal pillar for the linkage of the driver and gear pump, a fitting hole 9 is provided to the main moving gear of the pump, the pump and driver are fitted, and thereafter, a firm fixation is executed by a hinge 10 for fixing a shaft. By using the pump, for example, the gear pump, in which the displacement in the middle of the drive is fixed, a stable liquid sending can be secured for a long period.
