<P>PROBLEM TO BE SOLVED: To provide a light and small pumping system designed based on human engineering which can reduce force required for discharging a material from a syringe by using a low viscous and inexpensive secondary incompressible fluid in a connection tube to enable a quantity of normally expensive injected fluid to be reduced. <P>SOLUTION: This system comprises: a hand piece with a liquid pressure pump operated by a lever and a fluid storage tank; a connection tube; and a remote connector sealed to the syringe body including the viscous material. The pump discharges the fluid from the fluid storage tank to the distal end of the syringe via the connection tube and the fluid presses a plunger of the syringe to discharge the viscous material from a primary chamber of the syringe. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
