    摘要： Embodiments provide aerosolization device for providing aerosolized medicament to user. The aerosolization device includes conduit, aerosol generator, fluid receiving chamber, restrictor within the conduit, and indicator mechanism. Conduit has an inner wall and a mouthpiece end for causing an inspiratory flow. Aerosol generator includes a vibratable mesh laterally offset from the inner wall. Fluid receiving chamber receives liquid medicament. At least a portion of chamber is tapered such that liquid medicament is directed onto vibratable mesh for aerosolization. Restrictor defines a plurality of apertures that provide increases in pressure differential that vary with inspiratory flow rate within conduit and provide relatively laminar flow downstream of restrictor. Indicator mechanism indicates a state of flow parameters relative to a predefined range. Aerosol generator is configured to aerosolize at least a portion of liquid medicament only when flow parameters of the inspiratory flow are within range.

    摘要翻译： 实施例提供用于向使用者提供雾化药物的雾化装置。 雾化装置包括导管，气溶胶发生器，流体接收室，导管内的限流器和指示器机构。 导管有一个内壁和一个吸嘴端，用于引起吸气流。 气溶胶发生器包括从内壁横向偏移的可振动网。 流体接收室接收液体药物。 腔室的至少一部分是锥形的，使得液体药剂被引导到可振动网上用于雾化。 限流器限定多个孔，其提供随着管道内的吸气流率而变化的压差增大并且提供限流器下游的相对层流。 指示器机制指示相对于预定范围的流量参数的状态。 气溶胶发生器构造成仅当吸气流量的流量参数在范围内时才使至少一部分液体药剂雾化。
