Patent ID: 8603025

Claim:
A gas-assisted fluid-dispensing device configured to deliver an aerosol onto a surgical site, the fluid-dispensing device comprising: a syringe configured to contain a fluid, the syringe including a distal end and a proximal end with a plunger extending from the proximal end; a spray nozzle tip coupled to the distal end of the syringe and configured to generate the aerosol; a housing including a first housing portion, a second housing portion configured as a handle, and a docking port on the first housing portion configured to receive the syringe; a trigger coupled to the housing; an actuating member coupled to the first housing portion and operatively coupled to the trigger, the actuating member configured to apply a force to the plunger of the syringe to discharge the fluid from the syringe into the spray nozzle tip when the trigger is actuated; a self-contained pressurized gas source coupled to the housing for movement with the housing, and the pressurized gas source further operatively coupled to the spray nozzle tip; and a control mechanism operable to control delivery of a pressurized gas from the pressurized gas source to the spray nozzle tip for atomizing the fluid within the spray nozzle tip and generating the aerosol, the control mechanism operable to control delivery of the pressurized gas independent of the operation of the trigger.
