Abstract:
1. A nebulizer comprising: a nozzle member for discharging an oxygen gas from an orifice; an aerosol forming member that is disposed at a position corresponding to the orifice of the nozzle member, including a suction pore for sucking water by the oxygen gas flow discharged from the orifice and a baffle for forming the sucked water into a fine aerosol; an air suction pore that sucks air in response to the discharge of the oxygen gas from the orifice of the nozzle member; wherein the nozzle member includes the orifice that discharges the oxygen gas toward the aerosol forming member along an axial core of the nozzle member; a flow-out pore of the oxygen gas is formed on a side wall of the nozzle member, a valve that is disposed on a peripheral portion of the nozzle member at a position opposed to the flow-out pore closes the flow-out pore in a state where no oxygen gas is supplied to the nozzle member and opens the flow-out pore in response to a pressure of the oxygen gas supplied to the nozzle member; and when the pressure of the oxygen gas supplied thereto is less than a predetermined value, the oxygen gas is discharged from the orifice, and when the pressure of the oxygen gas supplied thereto is higher than the predetermined value, the oxygen gas is discharged from the orifice, while being also allowed to flow out from the flow-out pore to be mixed with the aerosol.
