Abstract
A sampling device is constructed having an airflow path from a size-selective inlet to a device outlet, without using any tubing. The size-selective inlet includes at least one of an impactor, a filter, a cyclone, and an inhalable inlet. The device includes a sampling assembly configured to be removably coupled directly to a sampling device housing (e.g., without using tubing), and an airflow assembly that may be constructed without using tubing.
Claims20
A portable, size-selective aerosol sampling device, comprising:
- a housing at least partially enclosing an inner chamber, the housing comprising an upper housing portion and a lower housing portion, the upper housing portion comprising a size-selective inlet;
- and
- an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path from the size-selective inlet through the sampling device to an airflow outlet of the sampling device, the airflow assembly comprising:
- a portion of a printed circuit board (PCB);
- and
- a manifold configured to be sealably coupled to the portion of the PCB to define at least one airflow channel disposed between an inner surface of the manifold and an outer surface of the PCB.
A portable size-selective aerosol sampling device, comprising:
- a housing at least partially enclosing an inner chamber, the housing comprising an upper housing portion and a lower housing portion, the upper housing portion comprising a sampling assembly receiver;
- and
- a sampling assembly having a coupling interface configured to be removably mated with a corresponding coupling interface of the sampling assembly receiver, the sampling assembly comprising a cyclone assembly, the cyclone assembly comprising:
- a cyclone body having an at least partially conical cavity defined therein, wherein the cavity extends from a lower end of the cyclone body toward an upper end of the cyclone body;
- a cyclone inlet aperture defined through the cyclone body;
- a cyclone floor disposed adjacent the lower end of the cyclone body;
- and
- a size-selective cyclone outlet aperture defined through the cyclone floor.
A portable, size-selective aerosol sampling device, comprising:
- a housing at least partially enclosing an inner chamber, the housing comprising a size-selective inlet;
- an airflow assembly disposed within the inner chamber, the airflow assembly comprising:
- an airflow channel;
- and
- one or more ultrasonic micropumps configured to generate a flow of air within the airflow channel.
