摘要：
An aerosol transition adapter for delivering an aerosolized active agent to a patient, the aerosol transition adapter includes a housing having a proximal end and a distal end, the proximal end having an aerosol passage for receiving an aerosol produced by a source of aerosol comprising an aerosolized active agent and the distal end having an exit port, the housing having a length between the distal end and the proximal end. The adapter also includes a carrier gas connection port for receiving a carrier gas from a gas source, the gas source being a positive pressure generator, which is in communication with a plurality of carrier gas exit ports, the plurality of carrier gas exit ports are arranged adjacent to the aerosol passage in a pattern that partially encircles the flow of aerosol. The adapter also includes an inner cavity, which is adapted to receive the aerosol from the aerosol passage and the carrier gas from the plurality of carrier gas exit ports and to direct streams of carrier gas to at least partially encircle and flow in parallel with a main direction of a flow of the aerosol along the length of the housing toward the exit port to provide a low turbulence flow of aerosol and carrier gas. The adapter further includes an exit port on the distal end of the housing for delivering the aerosol to a patient in need of an aerosolized active agent.
