Device having syringe dispensers for administering therapeutic substances using a high velocity liquid-gas stream

A device for administering a liquid therapeutic substance to tissue, including:

• a housing having a liquid inlet port;
• a gas inlet port connected to a pressurized gas source;
• at least one therapeutic substance supply assembly mounted onto said housing,
• each therapeutic substance supply assembly including:
• at least one syringe dispenser connector configured for receiving a syringe dispenser containing a predefined quantity or concentration of the liquid therapeutic substance, each syringe dispenser in fluid flow communication with one of at least one valve projecting from and external to said assembly, each of said at least one valve is associated with a different syringe dispenser and user operable between an open and a closed position, said at least one valve is adapted for control of a continuous flow of said at least one liquid therapeutic substance during operation of said device,
• said syringe dispenser includes a container configured to store the liquid therapeutic substance and a piston configured to be pulled into the container as the liquid therapeutic substance is removed from said container under suction so as to flow through said at least one valve;
• and,
• at least one liquid conduit in liquid communication said liquid inlet port and said at least one syringe dispenser connector;
• a stream jet delivery nozzle arrangement in fluid flow communication with said gas inlet port and in fluid flow communication with said conduit, operative to deliver the liquid therapeutic substance in an elevated velocity flow of gas discharged from said delivery nozzle arrangement at a predetermined concentration.
