Patent ID: 8459098

Claim:
A physiological sampling pump (PSP) for providing rapid response to breathing, comprising: a pump body including an outer thermo-resistant housing; at least one interchangeable sampling component for collection of an aerosol for accomplishing size selective sampling and total sampling of particulates, said component including at least one interior located valve in communication with said pump body via a first air tube and a second valve control cable; said sampling component further comprising a cyclone sampling head used for size-selective sampling of particulates and including an air sampling cyclone with a funnel shaped top; a tubing extending from said cyclone sampling head to a first cassette in turn containing a dummy filter and support pad, a further PSP cassette incorporating a collection filter element and support pad and fitting onto a top of said cyclone funnel; and said valve rapidly switching in proportional response to variations in inhalation within said sampling component, in order to provide effective test sampling while maintaining constant pump speed and airflow through a pre-collector cyclone component.
