PURPOSE: A syringe pump is provided to expand the life expectancy of an o-ring of a piston and simplify the entire structure of a pump by simplifying the contact part of a solution. CONSTITUTION: A syringe(10) includes a lower part in connection with an inhaling pipe(11) and an opened upper part. The inside of the syringe is hollow. A piston(20) is inserted through the upper side of the syringe and introduces a solution into the inside of the syringe through the inhaling pipe. The inhaled solution is discharged through a discharging pipe(21). An elevating unit fixes the piston and vertically elevates the syringe. The elevating unit includes a mounting block(30) and a ball screw(50). The mounting block is integrated with the syringe. The ball screw rotates by the operation of a motor(40) and vertically elevates the mounting block. |
