Abstract: A gas-assisted fluid-dispensing device configured to deliver an aerosol onto a surgical site. The fluid-dispensing device includes at least one fluid chamber configured to contain a fluid. The fluid chamber has a distal end and proximal end. A plunger extends at least partially into the fluid chamber from the proximal end. A spray nozzle tip is fluidly coupled to the distal end of the fluid chamber and is coupled to a gas supply. The tip is capable of generating aerosol with a gas from the gas supply and the fluid from the fluid chamber. A housing has an upper portion with a docking port configured to operably receive the fluid chamber. An actuating member is operably coupled to a plunger and is configured to apply a force to the plunger to discharge fluid from the fluid chamber and into the tip.

Abstract: A gas-assisted fluid-dispensing device configured to deliver an aerosol onto a surgical site, and methods of use. The device includes a support structure and a fluid chamber. The fluid chamber contains a fluid and has a distal end and a proximal end. A piston is positioned within the fluid chamber. A spray nozzle tip is fluidly coupled to the distal end of the fluid chamber and includes a gas inlet. The tip generates the aerosol with a gas from the gas inlet and the fluid from the fluid chamber. A pneumatic switch has a first stage and a second stage. The first stage permits gas flow through the pneumatic switch and into the gas inlet of the tip. The second stage permits gas flow through the pneumatic switch and into both the gas inlet of the tip and into the fluid chamber.

Abstract: A static mixer (10) for mixing a fluid flow includes a mixer conduit (12) and a plurality of mixer baffle segments (30, 32) configured to divide and rotate the fluid flow. Each of the mixer baffle segments (30, 32) may consist of a plurality of planar baffle plates (40, 42, 44, 50, 52, 54, 56) interconnected together to minimize complex geometries that are difficult to mold. The planar baffle plates may be connected by chamfered surfaces (66) to minimize sharp corners which damage sensitive fluids in the mixer conduit (12). Each mixer baffle segment (30, 32) may include three planar divider baffle plates (40, 42, 44) oriented parallel to the direction of flow (F) and four planar occluding baffle plates (50, 52, 54, 56) oriented perpendicular to the direction of flow (F). The static mixer (10) thoroughly mixes two or more fluids passing through the mixer conduit (12).
