摘要： PROBLEM TO BE SOLVED: To provide a new aerosolization device comprising a housing having a mouthpiece, and a flow path arrangement wherein fluid is communicated with the mouthpiece. SOLUTION: The flow path arrangement has a flow regulating valve and a threshold valve, wherein the threshold valve is configured to open at a first vacuum level and to close at a second vacuum level lower than the first vacuum level. The housing includes a region which is allowed to hold powder while fluid is communicated with the flow path arrangement, and is constituted so that air drawn through the mouthpiece opens the threshold valve once the first vacuum level is exceeded and remains open until the vacuum falls below the second vacuum level. The flow rate of the air drawn through the mouthpiece is regulated by the flow regulating valve to remain within a certain range while the threshold valve remains open. COPYRIGHT: (C)2009,JPO&INPIT
