600343 A plasma separation device 500 comprising a filter comprising a microporous membrane 650 and having an upstream surface and a downstream surface, a housing 400 with an inlet 250a, a downstream chamber 202, and an outlet, and at least one air channel. The housing 400 defines a fluid flow path between the inlet 250a, the downstream chamber 202, and the outlet, with the filter disposed in the housing 400 across the fluid flow path. The outlet and the air channel are spaced apart and are arranged such that, when a negative pressure is created in the downstream chamber 202 through the outlet, air passes into the downstream chamber 202 via the air channel and sweeps plasma from the downstream surface of the filter and through the outlet. |
