ABSTRACT:
A flow baffle for use in an aerosol therapy system including a jet nebulizer device, which is connected by large bore tubing to a face tent worn by a patient, with the water aerosol and oxygen-air mixture so delivered being free to pass through and out of the face tent. The flow baffle comprises a disc covering over the face tent inlet port and retained in spaced relationship thereto by a series of vanes, which fit snugly into the inlet tube of the face tent. Stop means on the vanes limit penetration thereof into the inlet tube so that the disc remains spaced from the port opening at least a predetermined amount whereby flow into the face tent is not materially impeded and there is no back pressure build up.
