摘要：
A gas-assisted fluid-dispensing device (10) for delivering an aerosol. The gas-assisted fluid-dispensing device (10) includes a syringe (14) that contains a fluid and includes a distal end (18), a proximal end (20), and a plunger (24) extending proximally from the proximal end (20). A spray nozzle tip (26) is configured to generate the aerosol and is coupled to the distal end (18) of the syringe (14). The gas-assisted fluid-dispensing device (10) further includes a housing (44) having first and second housing portions (52, 54). The first housing portion (52) includes a docking port (42) for receiving the syringe (14) the second housing portion (54) is configured as a handle. A trigger (50), coupled to the housing (44), is operably coupled to an actuating member (58) that is configured to apply a force onto the plunger (24) of the syringe (14) and discharge the fluid from the syringe (14) and into the spray nozzle tip (26). A self-contained pressurized gas source (72) is coupled to the housing (44) such that it moves with the housing (44) and is also coupled to the spray nozzle tip (26). Delivery of a pressurized gas to the spray nozzle tip (26) is controlled by a control mechanism (76) and atomizes the fluid to generate the aerosol.
