摘要:
The device for injecting a high viscosity material into a cannula includes a body having a material-moving member disposed therewithin which separates the body into a first cavity adapted to receive an incompressible fluid and a second cavity adapted to receive a high viscosity material. A pressure applicator, including a housing having incompressible fluid, is remote from but connected to the body by an extension line providing fluid flow between a fluid outlet of the pressure applicator and the first cavity. First and second check valves within the housing control the flow through the housing. The power piston generates negative pressure within the housing to draw the incompressible fluid in when the piston is extended, and generates positive pressure within the housing, forcing the incompressible fluid out through the second check valve and the fluid outlet and into the first cavity of the non-compliant body, when the piston is depressed.
