    • Particle collector apparatus are used to separate particles from an entrained gas. Typically, flow is effected by means of applying a vacuum at one end, where the vacuum is produced by means of a mechanical, reciprocating piston, type vacuum generator. The present invention provides a particle collector apparatus (10), for use in testing medical devices which emit particulates, such as inhalers, comprising a collection vessel (210) having an inlet (230), for connection with the device to be tested, and an outlet (240), and a first vacuum generating unit (10) connected to the outlet, wherein the first vacuum generating unit is powered by of a first vacuum-forming fluid to produce a first at least partial vacuum thereby inducing a flow of a first sample fluid in a first direction through the collection vessel (210) from the inlet to the outlet, wherein the collection vessel is an impactor or an impinger.
    • 颗粒捕集器用于从夹带的气体中分离出颗粒。 通常,通过在一端施加真空来实现流动,其中真空通过机械的往复式活塞式真空发生器产生。 本发明提供了一种用于测试发射微粒的医疗装置(如吸入器)的颗粒捕集器装置(10),其包括具有入口(230)的收集容器(210),用于与要测试的装置连接;以及 出口(240)和连接到出口的第一真空发生单元(10),其中第一真空发生单元由第一真空成形流体驱动以产生第一至少部分真空,从而引起 第一样品流体沿着第一方向通过收集容器(210)从入口到出口,其中收集容器是冲击器或冲击器。
