Abstract
A portable sampling device includes a housing at least partially enclosing an inner chamber and an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path. The airflow assembly includes a portion of a printed circuit board (PCB); 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; and one or more pumping elements positioned on the PCB.
Claims20
A portable 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 an inlet;
- and
- an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path from the 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);
- 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;
- and
- one or more pumping elements positioned on the PCB, each having an inlet exposed to a first environment and an outlet exposed to a second environment, wherein each outlet is sealed from the first environment at an interface with at least one of the inner surface of the manifold and the outer surface of the PCB.

- at least one pumping element positioned on the PCB, the at least one pumping element having an inlet exposed to a first environment and an outlet exposed to a second environment, wherein the outlet is sealed from the first environment at an interface with the outer surface of the PCB, the first environment comprising the at least one airflow channel.
A portable 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 an inlet;
- and
- an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path from the inlet through the sampling device to an airflow outlet of the sampling device, wherein the airflow path does not include any tubing, the airflow assembly comprising:
- a portion of a printed circuit board (PCB);
- 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, wherein the manifold is integrated with the housing;
- and
- at least one pumping element positioned on the PCB, the at least one pumping element having an inlet exposed to a first environment and an outlet exposed to a second environment, wherein the outlet is sealed from the first environment at an interface with the outer surface of the PCB, the first environment comprising the at least one airflow channel.
