摘要： An apparatus for operating a syringe has developed comprising that: an upper semi-cylindrical tube section, semi-circular groove shaped locking slot and lower semi-cylindrical tube section. The upper semi-cylindrical tube section is integrally formed an upper head part with a threaded hole for axial movement. The lower semi-cylindrical tube section forms a top portion, intermediate portion and end portion. A diameter (Dc) at the intermediate portion is larger than the diameter (Dtip) at end portion, which is gradually reduced from intermediate to end portion. The length of tapered portion is same as that of the constant diameter portion. A tip portion has formed an opened semi-circular shape to simply overlap the syringe over the syringe mounting device for easily snapping-in and out. The syringe piston moves downward with no reverse action when the piston press unit is rotated, so that it is possible to inject the precise amount of medical to a patient with constant pressure.
