NEEDLE-FREE LIQUID INJECTING DEVICE OF A DUAL CYLINDER TYPE CONTROLLING PRESSURE CAPABLE OF MINIMIZING VOLUME BY FORMING A DUAL CYLINDER SPRAY GUN WITH A DUAL PISTON CONNECTED COMPACTLY TO THE INSIDE OF A HOUSING

摘要

PURPOSE: A needle-free liquid injecting device of a dual cylinder type controlling pressure is provided to stably inject an injection with a pressure control unit controlling high-pressure compressed air in a housing.;CONSTITUTION: A needle-free liquid injecting device of a dual cylinder type controlling pressure comprises a housing(10), a dual cylinder spray gun(20), a pressure control unit(30), and a variable injection supply unit(40). An operating rod(21) injecting air pressure to a nozzle head(11) is formed on the dual cylinder spray gun. The dual cylinder spray gun moves back and forth the operating rod by steps. The pressure control unit is connected to the dual cylinder spray gun in the housing and controls air pressure supplied to the dual cylinder spray gun. The variable injection supply unit fixes various sizes of syringes(2).;COPYRIGHT KIPO 2012
