  • Universal physiologic sampling pump (PSP) capable of rapid response to breathing
    Patent number: 8459098
    Abstract: The present invention discloses a physiologic sampling pump (PSP) which uses at least one valve placed near the sampling medium to modulate air sampling to follow a person's inhalation rate and to obviate the sluggishness inherent in prior art PSPs caused by varying pump speed and by the propagation time through an air tube that connects the collection medium to prior art pumps thereby also obviating limitations inherent in system response, functionality, and accuracy. Moreover, by maintaining an essentially constant air flow through a cyclone at all times and through the collection medium while sampling, the present invention operates at known collection efficiencies, and is therefore capable of size-selective sampling of particulates as opposed to prior art PSPs that by varying the magnitude of air flow, make the separation efficiencies of pre-collection devices indeterminate and the samples worthless.
