An apparatus assembly is described providing hygienic conditions to obtain sputum after aerosol inhalation. It is composed of an ultrasonic nebulizer and a half-opened exhausting hood. The patient's head is placed under the hood which inhibits the delivery of expectorated germs into the environmental space. A continuous air flow in the direction of coughing is leading the sputum particles (droplet nuclei) towards a filter system. After decontamination the air may be let off outwards or back into the room.
描述了一种用于在雾化吸入后提供卫生条件以获取痰液的设备组件。它由超声雾化器和半开放式排气罩组成。患者头部置于罩下，可防止咳出的病菌传播到周围环境空间。咳嗽方向的持续气流将痰液颗粒（飞沫核）引向过滤系统。消毒后，空气可向外排放或再循环回室内。
