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

要解决的问题:提供一种新的雾化装置,其包括具有接口管的壳体和其中流体与接口连通的流路装置。 解决方案:流路装置具有流量调节阀和阈值阀,其中阈值阀被配置为在第一真空度下打开并在低于第一真空度的第二真空度下关闭。 壳体包括允许在流体与流路装置连通的同时保持粉末的区域,并且被构造成使得经过接口管抽出的空气一旦超过第一真空度就打开阈值阀并保持打开,直到真空降至低于 第二个真空度。 通过接口管吸入的空气的流量由流量调节阀调节,保持在一定范围内,同时阈值阀保持打开。 版权所有(C)2009,JPO&INPIT
