摘要： A manually operated hydraulic syringe includes a syringe barrel. The syringe barrel has an interior surface bounding a chamber extending from a first end to an opposing second end. A manual plunger has a distal end slidably disposed within the first end of the chamber. A hydraulic plunger is slidably enclosed within the second end of the chamber. Sealed in substantial isolation within the syringe barrel is a hydraulic fluid, such as water or oil. Coupled to the distal end of the syringe barrel is a nozzle or cartridge in which a dispensing material, such as a high viscosity fluid, can be selectively disposed. Manual advancement of the manual plunger within the first chamber results in pressurization of the hydraulic fluid. In turn, the pressurized hydraulic fluid advances the hydraulic plunger under a force greater than the force applied to the manual plunger. Advancement of the hydraulic plunger within the syringe body functions to dispense the dispensing material from the attached nozzle or cartridge.
